This is Crime House. When you're a teenager, anything feels possible. For some of us, it's a time of exploration, when we can experiment with our identities, try new things and have all sorts of exciting adventures. But our teenage years also come with challenges. The surge of hormones brought on by puberty can make us lose control of our emotions. It's easy to get angry, irrational, even dangerous. This was the case for Joran Van Der Sloot. Despite an idyllic upbringing with a loving family, Joran's teenage years took him down a dark path. A path that eventually led to the disappearance of a girl named Natalie Holloway and Joran being accused of murder. The human mind is powerful. It shapes how we think, feel, love and hate. But sometimes it drives people to commit the unthinkable. This is Killer. A Crime House original. I'm Vanessa Richardson.

When we think about murderers, we usually assume they had a challenging upbringing. But that wasn't the case for Joran van der Sloot. As a child, he had everything he wanted and more. Joran was born in the Netherlands, but when he was around 4, his family moved to the small Caribbean island of Aruba. Joran's father, Paulus, was a lawyer and got a job there working for the Aruban government. It would be a step up in his career and a chance for his family to live in paradise. Joran took full advantage of his new surroundings. He and his younger brothers, Valentin and Sebastian, spent their days exploring the sunny island, playing on white sand beaches and swimming in the warm Caribbean Sea. Their family wasn't rich, but they were well to do by local standards. They had a nice home in a small town called Neword on the north side of the island. The van der Sloots also had enough money to join a country club and send Joran and his brothers to private school. Joran excelled academically and had a particular gift for languages. In addition to his native Dutch and English, he fluently spoke the local Aruban language, Papiamento. Learning the native language allowed Joran to fit in better with his peers, who were mostly local Aruban boys. They typically looked down on expats, but Joran was an exception. He was one of them. All in all, it was a happy childhood. Then Joran hit puberty. It happened earlier for him Than it does for most boys. Doctors called this precocious puberty, and it seems to have affected his personality drastically. Joran became violent toward his brothers, Hitting them, and at one point, destroying Valentin's cell phone. Joran also began lying to his parents. Whenever they caught him, he'd spin more lies to get out of it. But rather than punish him, Joran's parents sent him to therapy. They also urged him to take yoga classes so he could learn to handle his emotions. But nothing seemed to work. Joran's behavior just kept getting worse.
Dr. Tristan Engels
During puberty, the adolescent brain undergoes significant changes, Particularly in areas responsible for regulating emotions, Decision making, and just social understanding. For teenage males, this developmental phase involves both hormonal shifts and neurological remodeling that shapes their psychological and behavioral experiences. So neurologically, the brain's limbic system, which is responsible for emotion, Develops more rapidly than the prefrontal cortex, which is involved in rational thought and impulse control. And this imbalance can result in mood swings or impulsive behavior and intense emotional responses, like you described. But precocious puberty, which typically starts before the age of nine in males, it makes those changes that I just described more accelerated. So the brain is essentially exposed to adult level hormones before it is cognitively and emotionally ready to handle them. And I think it's also worth noting, Even though most cases of precocious puberty Are idiopathic, which means unknown, they don't know the cause. There have been instances where it was connected to a brain tumor or issues with the pituitary or adrenal glands, Both of which are involved in critical hormone production. And if this is the case for your hand, if that's somehow involved, then that could mean a lot more ongoing biological factors to consider when conceptualizing his behavior, as well as, you know, what medically could have been done to maybe help address this.
Vanessa Richardson
Can puberty actually increase aggression?
Dr. Tristan Engels
Puberty doesn't cause aggression directly, but it creates conditions that can increase the likelihood of aggressive behavior, Particularly in males. So, for example, there's an increase in testosterone, and that can increase competitive or dominance behaviors. And when you combine that with the social changes that adolescents experience, Especially in Joran's case, it can make them more prone to aggression. And studies actually suggest that boys with precocious puberty, in particular, May be more prone to conduct problems, substance use, or acting out. And this is partly due to that disconnect I mentioned between undergoing early physical maturation and the simultaneously having underdeveloped emotional and cognitive control.
Vanessa Richardson
Well, for Joran, puberty didn't only change his personality, it also changed him physically. He quickly grew bigger than most of his peers, but by age 17, he was 6 foot 4 and muscular, which made him even more dangerous. Before long, it got to a point where he wasn't just lashing out at his brothers anymore. In one troubling incident, Joran got into an altercation with a homeless man and threw him off a low bridge into the water below. In another, he allegedly pushed a classmate through a glass display case at a movie theater. Most people would probably get arrested for that kind of behavior, but. But not Joran. It's not clear if his father's connections helped, but it seems like he always weaseled his way out of trouble and he got into plenty of it. Eventually, Joran's aggression issues became so bad that his parents moved him into a detached apartment behind their house. While this made things more peaceful for the family, it also had a big unintended side effect. Joran now had unchecked freedom to come and go as he pleased. And it was something he took full advantage of. Of many of Joran's friends were local Aruban boys whose parents had jobs in hotels and casinos on the island. They often worked all night, leaving their sons free to do as they pleased. By his senior year of high school, Joran was constantly sneaking out of his detached apartment to go out partying with his friends.
Dr. Tristan Engels
So early intervention is critical for any healthcare related event, even if it's mental health. And therapy can be life saving and beneficial, whether it's done early or when someone is at risk or to just manage symptoms or conditions that already exist. And I say that because I don't want anyone to get discouraged when hearing that therapeutic intervention quote didn't work for Joran. There are many reasons why therapy may seem ineffective. And it's often unrelated to the therapy itself. Frequently it's related to a poor therapeutic alliance between the patient and the therapist or the individual's commitment to therapy. But also it can be related to their environment outside of therapy. So a person' can hinder progress, especially if the patient's not intrinsically invested themself. And that sounds like the case for Joran. So let me explain. On the surface, it seems like his parents are doing everything right and they have loving intentions, they provide for their family, his basic needs are met and then some. They've clearly bailed him out of trouble and they've placed him in therapy, even got him into yoga. But it also seems like they are emotionally distant from Joran. They may have assumed that therapy Alone was enough to, quote, fix him. And may not have considered that they, too, need to be a part of the solution. They need to learn effective tools like appropriate emotional support, enforcing rules, setting boundaries, and how to stop enabling or reinforcing his bad behavior. If they're not learning along with urn or they are not setting realistic expectations about how fast he can make progress in therapy, then of course it's going to appear as if it's ineffective because their next effort is is to move him out of the house. It's once again distancing themselves from the problem for their own peace without giving him boundaries or rules. Instead, what they're doing, whether they're aware of it or not, is reinforcing his negative behavior. Because for most kids his age, being given their own apartment after nearly killing a homeless man and assaulting a classmate would be considered a reward. And that's likely how he viewed it, too.
Vanessa Richardson
For Joran and his friends, their partying took on a common pattern. They would typically start their night by getting drunk on the free cocktails handed out at the casinos. Then they'd hit the clubs trying to hook up with girls. They even had a nickname for their posse, the pimpology crew. And Joran was obsessed with sex. He frequently set his sights on American girls visiting the island on vacation. Sex was just one of Joran's many vices. He also seems to have become an alcoholic and a gambler, gambling addict, all by age 17. His favorite game was poker. He was a good player, skilled at sensing weakness in others and excellent at bluffing. Before long, Joran was a regular fixture around the card tables of the island's many casinos. And even though he knew what he was doing, he still had his fair share of losses. To continue funding his addiction, Joran apparently started stealing from his parents and lying about it whenever he got caught.
Dr. Tristan Engels
So gambling taps into a complex network of psychological mechanisms that can make it highly addictive and, for some, dangerously difficult to stop. And that's where Uran's getting into. He's stealing for money. Gambling activates the brain's reward system. And when a person places a bet, anticipates a win, or experiences a near miss, the brain releases dopamine, which is a neurotransmitter associated with pleasure, motivation, and reinforcement. And interestingly, research shows that dopamine is released not just when someone wins, but even during the anticipation of a win, which sustains that excitement and engagement that makes it addictive. But there is also the psychological mechanism of intermittent reinforcement, which is part of Behavioral theory. And essentially, that's a reward schedule in which the payout is unpredictable. And this is highly addictive because the uncertainty itself is reinforcing. Incidentally, this is yet another environment in which Yoran's concerning behaviors are being reinforced because he's not of legal age to drink or gamble. Even in Aruba, the legal age is 18. So once again, no one is there setting rules and applying them to Yorin. And that, too, elevates his risk for continuing to be addicted to gambling and drinking.
Vanessa Richardson
Are there certain psychological traits that make someone more susceptible to gambling addiction? And does gambling affect young people like Joran differently than it does adults?
Dr. Tristan Engels
Yes. So people with impairment and impulse control, emotional regulation, and our sensation seeking are at a greater risk. Early exposure to gambling, especially in someone his age, can increase the likelihood of addiction because his prefrontal cortex is still developing. And adolescents experience increased dopamine activity already, which makes them more responsive to the thrill and reward cues of gambling. So all of these contribute to how he could become addicted and how much more difficult it could be for him to stop.
Vanessa Richardson
It definitely doesn't seem like Joran's parents knew how bad the problem was, because on the afternoon of May 29, 2005, 17 year old Joran and his father, Paulus, were playing in a poker tournament together. Joran's mom Anita was out of town, and it seems like Paulus was trying to bond with his troubled son. They were playing at a casino called the Excelsior. It was on the second floor of the Aruba Holiday Inn, the oldest casino on the island. After about two hours, Joran was out of chips and and folded his last hand. Palace needed to head home to take care of Joran's younger brothers. So he gave Joran his chips and told him he could just call him later when he needed a ride home. But soon after Paulus left, Joran was out of chips again. He wasn't ready to call it a night, though, so he headed to a blackjack table and settled in. A few minutes later, four teenage girls about his age sat down at the table with him. They were American high school students from Alabama. They looked like they could have been cheerleaders. Their names were Ruth, Lee, Catherine, and Natalie. None of them knew it yet. But the decision to sit down at this particular blackjack table next to this tall boy with honest brown eyes was about to change all of their lives forever and set off one of the most notorious criminal investigations of. Of all time. Okay, I'm gonna switch gears for a moment because we have Something special for you today. You might already know this, but Crime House has a sister company called Open Mind, and they recently launched a new show that I think you're really gonna love. It's called Mantra with Gemma Sbeg. And speaking of which, Gemma's actually here in the studio with me right now. Hi, Gemma.
Gemma Sbeg
Hi, Vanessa. Thank you so much for having me.
Vanessa Richardson
Of course. You know, I have to say, I really love love Mantra. Truly. It actually really helps me balance the true crime work we do.
Gemma Sbeg
Oh, my goodness. Honestly, I can only imagine. And I can only imagine how you do it every day, considering I'm a bit of a true crime girly myself. Like, I love Killer minds. I love diving into, like, minds of serial killers. But I definitely also need to be centered in some more, like, spiritual wellness grounding exercises every now and again.
Vanessa Richardson
Oh, yeah, we need balance, for sure. It's so important. And truly, actually, the stuff we talk about on Killer Minds, also, it has a lot to do with the psychology and, of course, of Killers. But, you know, here we're. We're a lot healthier with you. I love the balance that you create also, because Mantra is so great. I listen to it just to kind of bring me back, you know, into the piece. I just love it. Now, of course, Mantra is a pretty huge shift from what we usually cover here at Crime House. And can you give our listeners a quick rundown of what the show's about?
Gemma Sbeg
Well, I feel like if you like psychology and you like going deep into the minds of killers, you might also like going deep into your own mind and kind of looking into some closets, finding some little corners that you haven't peeked into for a while. And on Mantra, I basically share a mantra, a powerful phrase every Monday. And then with that, personal stories, reflections, practical tips, wisdom, and some psychology, some lessons from science. And this season, we're really exploring some pretty impactful themes. We're releasing an episode on external validation. Learning to trust yourself, honoring your boundaries, healing your inner child. And really, my goal is to offer listeners a place to really reflect without being judged. And then also find small nuggets of wisdom, little powerful tools so that you can leave the episode and feel grounded, feel intentional, and feel more connected to yourself. No matter what's happening in your life, you have this space to come back.
Vanessa Richardson
To, and you do all of that in such a beautiful way. I love it. And at the end of today's episode, we're actually going to play a short preview from an episode of Mantra, so make sure you stick around for that I know we talk about some pretty intense stuff on Killer Minds and if you're anything like me, sometimes you just need a moment to reset and clear your head afterward. If that sounds like you, just search mantra and follow wherever you get your podcasts.

There are some people who just have a glow about them, a way of bringing joy, laughter and love into the lives of everyone they meet. Natalee Holloway had that glow. Natalee was a small girl with long blonde hair who loved Lynyrd Skynyrd and the wizard of Oz thanks to her time growing up in Mississippi and Alabama. She had a charming southern drawl and she wasn't shy about Sharing her thoughts and feelings. Natalie's friends remember her as confident and outspoken. The kind of girl who had a strong opinion about everything and wasn't afraid to share it. But she was funny too. Always cracking her friends up with ridiculous jokes. Like when she claimed that back in Mississippi, everyone called her Hootie Hoo Holloway. That little story earned her the nickname Hootie. But Natalie knew when to be serious as well. She was an excellent student who got straight A's while also juggling a part time job and a ton of extracurriculars. From dance team to studio student government. She'd been accepted into the University of Alabama for the fall of 2006 on a full academic scholarship. She planned to become a doctor. But while Natalie was exuberant and bright, she also led a pretty sheltered life. Her parents say she never drank or dated, and her friends remember her as a strict rule follower. Her mother Beth once summed up Natalie by saying she was very smart but very naive.
Dr. Tristan Engels
So we already talked about the changes that happen in the brain of males going through puberty. So let's talk about what happens with females. So females experience a surge in the sex hormones known as estrogen and progesterone in addition to rising levels of testosterone. And these hormonal surges also correlate with a rise in depressive symptoms, anxiety disorders, and even self harm behaviors. During puberty, females also experience a more reactive or sensitive limbic system, which I mentioned is the emotional center of the brain. And this can lead to mood swings, impulsivity and sensitivity to social dynamics, which is not unlike males. They could as a result, exhibit increased defiance or emotional outbursts.
Vanessa Richardson
Natalie was naturally cautious and a rule follower. But during this time in her life, Would there be a psychological reason she'd want to experiment with being more wild?
Dr. Tristan Engels
Yeah, in part. At least during puberty, the part of the brain known as the striatum is still developing. And this is tied to reward seeking, motor control and risk taking behavior. And as it's developing, it can cause an increased sensitivity to rewards or peer approval, which may lead to more experimentation or risky choices, Particularly in emotionally charged situations. And she's also with her peers right now and that can also influence that. So this puts them at an elevated risk of exploitation as well, Especially from older peers or people of authority.
Vanessa Richardson
Well, in May 2005, 18 year old Natalie finally had the opportunity to break out of her shell and go a little wild. She was about to go on the Mountain Brook High school senior class trip to Aruba. The senior trip was a Yearly tradition at Mountain Brook, a chance for students to have one last bonding experience with their friends before they went their separate ways. It would be three days of relaxing in beautiful Aruba. 124 students were going with seven adult chaperones. Natalie's dad Dave was worried about his daughter going on a trip without much supervision. But her mom Beth wasn't worried at all. Natalie's stepbrother had gone on the same trip two years earlier and had a great time. Plus, with so many students going, Beth figured Natalie would always be surrounded by friends who could make sure she stayed safe. Natalie was thrilled. She and her friends painted T shirts that said Aruba and packed their bathing suits. On May 26, 2005, she and her class landed on the island and checked into the Aruba Holiday Inn. The next three days were full of classic spring break style partying. With so few chaperones, the students were largely left to do whatever they wanted. Since the drinking age there was 18. Natalie and her friends would start the morning with cocktails, then spend the day lounging on the beach. They'd go back to the hotel for a nap before dressing up for dinner, followed by dancing at the clubs and bars until the early hours of the next morning. It was all Natalie could have wanted a senior trip to be. She was finally letting loose and having a blast. On the last evening of the trip, Natalie and her friends decided to head to the hotel's casino, the Excelsior. The girls settled in at a blackjack table. A tall boy about their age was already there. Soon they began chatting. The boy who spoke perfect English told them his name was Joran. 17 year old Joran had learned a few things from his years of hitting on tourists. For one, he knew foreign girls tended to look down on local Arubans and distrust them. So when he began chatting with Natalie and her friend, Joran reportedly told them he was actually a nice a 19 year old university student from the Netherlands. He said he was a tourist just like them visiting Aruba on holiday. The girls had no reason to suspect this charming stranger was lying. They had a good time gambling together until the girls decided to quit while they were ahead and leave the casino. Before heading out, they told Joran they'd be at Carlos and Charlie's, a popular tourist bar later that night. They invited him to come. Joran played it cool and said he might show up if he had time. But in reality, he would definitely be there. After Natalie and her friends left the casino, Joran called his dad to come pick him up. Once he got home, Joran hung out in the main house doing homework, then said he was going to bed in his detached apartment. After the lights in the main house went dark, Yorin slipped out. His friends, brothers Deepak and Satish Kalpo, picked him up in Deepak's silver Hond Pacific. Then they headed to Carlos and Charlie's. They arrived at the bar about an hour before last call. The place was full of students from Middlebrook High, drinking, dancing and celebrating the last night of their senior trip. Joran quickly spotted the girls he'd met at the Excelsior. Soon he was chatting with one in particular, the pretty blonde Natalie. At 1am the bar closed for the night and the throng of students poured out into the warm Caribbean night. As Natalie's classmates waited for taxis back to the Holiday Inn, a few of them saw Deepak's silver Honda drive past. Natalie, smiling and carefree, was leaning out the back window. It was the last time any of them would see her.
Dr. Tristan Engels
So let's talk about this decision to get in the car from an evolutionary perspective. We are wired to trust other people because it's essential for survival and thriving as a species, and we're biologically wired for connection. We tend to assess a person's trustworthiness based on whether they demonstrate competence, integrity, caring, and dependability. And when it comes to strangers, we tend to trust them more if they resemble people we know or they are familiar to us. So Natalie and her friends, for example, may have been more trusting of Joran because he was presenting as a student, also from another country, and pretending to be a tourist, just like they are. To them, he is within a social system that they know and were familiar with, and therefore likely comfortable with as well.
Vanessa Richardson
Why would a normally cautious person like Natalie trust a stranger like Joran enough to get in a car with him at this point?
Dr. Tristan Engels
So we tend to push our boundaries and limit tests when we start to get more autonomy. It's part of exploring our identity and our independence. If Natalie was experiencing any degree of internal pressure, being a rule follower, or even peer pressure, then this could be a way to escape that and validate herself and her peers. But it's also important to discuss the role of alcohol in this. Alcohol disinhibits the prefrontal cortex, which is not even fully developed in Natalie, and it can greatly impair judgment and reasoning. And as a result, Natalie's ability to think rationally is diminished. They also spent most of the evening together with both of their respective friend groups, which may have lowered her appraisal of risk leading to the decision to get in the car with him. So despite whether or not she was taking a risk, she didn't know that, right? She's still the victim. And her decision to get into his car does not make her to blame in any way, shape or form. And I just want to make that very clear.
Vanessa Richardson
When Ruth, Lee and Catherine woke up on the morning of May 30, they saw their fourth roommate. Natalie hadn't slept there the night before. Her bed was still made and her luggage was laid out where she'd left it. Her passport was even on top of her suitcase so she'd be ready to go to the airport on time.
Dr. Tristan Engels
Time.
Vanessa Richardson
At first, her friends didn't think it was odd. Students had been swapping rooms throughout the trip, crashing wherever they happened to end up. At the end of the night, they assumed Natalie must have stayed with some other friends in another room. But by mid morning, as the students and chaperones gathered in the lobby to head out to the airport, it became clear Natalie wasn't there and no one knew where she was. Her friends were distraught. Natalie would never be late like this. Something was definitely wrong. The chaperones were concerned, but hopeful that Natalie would return to the hotel soon. They decided to get the rest of the students on their flight home, but leave one chaperone in Aruba until Natalie turned up. At this point, it also fell to another chaperone, Jody Behrman, to make a difficult phone call. She dialed the number for Natalie's mother, Beth, and told her her daughter was missing. Beth was in a car with a few friends when she got the call from Jody. But instead of breaking down, she stayed calm and focused. She asked her friend to pull over and let her take the wheel, then immediately started driving toward the airport. On the way, Beth dialed 91 1. She told the dispatcher her daughter had gone missing in Aruba. Next, Beth called her husband, Natalie's stepfather, George Twitty. She told him to book them a flight to Aruba as fast as possible. But he did one better. By the time Beth reached the airport, a family friend had chartered them a private jet. Soon Beth was on board with George and several friends who had volunteered to come help. They left one seat open on the plane for Natalie.
Dr. Tristan Engels
Let's talk about fear and panic because they're not just emotional reactions to a crisis situation like this. They are a neurobiological response for survival. They are adaptive emotions, but they contemporarily override rational thought, distort memory and drive behavior. That doesn' always reflect the person's normal functioning. When someone is experiencing fear or panic, the brain shifts power away from the prefrontal cortex, which I've covered already, and what that function is, and then it hands it over to the amygdala and that's the brain's emotional and emergency response center. This can result in decision making that becomes reactive, impulsive and emotionally driven rather than reflective and deliberate.
Vanessa Richardson
I'm curious, in a crisis situation, are there psychological reasons that some people are able to remain calm and others just completely pan?
Dr. Tristan Engels
So that comes down to a complex mix of biology, experience, personality, and learned coping skills. So let's talk about Beth, for example. She seemingly remains calm. She's been a mother for at least 18 years, and perhaps her experiences as a mother have taught her that maintaining calm in a crisis is essential for her to remain rational, deliberate, and solution focused. She may have learned appropriate coping skills from past experiences, or her personality is one of high emotional stability. Also. Also, she's not in the same country as Natalie. And Beth seemingly has learned how to focus on what she has control of in the moment of a crisis. And that's exactly what she did. She first went to report her daughter missing while driving to the airport to get to Aruba, where she could have more control over searching for her daughter.
Vanessa Richardson
Beth. George and the others landed in Aruba around 10pm the night of May 30, 2005, less than 12 hours since Natalie had been been reported missing. They started the search at the Holiday Inn, where they met with the school chaperone who had stayed behind. She had no news on Natalie, but by now Beth and her family had pieced together a few clues from what Natalie's classmates had told them over the phone. Natalie was last seen in a silver car with a boy named Yorin. Her friends remembered him from the Excelsior Casino. He said he was a Dutch student staying at the Holiday Inn in Beth found someone who worked at the hotel and described Yorin. The employee knew who she was talking about instantly. But Yorin wasn't a guest at the hotel. He was a local punk who hung around the casinos. Beth would never forget the exact words the employee said. Next, he tends to prey upon young female tourists.

After Natalie Holloway's family arrived in Aruba on May 30, 2005, they learned that she was last seen with a local boy named Joran Van der Sloot. Aruba isn't very big, just about 75 square miles. It only takes an hour or so to drive across the whole island. But there were still plenty of places for Joran to hide. So Natalie's mom, Beth, and her stepdad George, along with a growing group of volunteers, fanned out across the island looking for anyone who might have more information. Eventually, they found a teenager on the beach who knew Joran and where he lived. By the time they could get the police to meet them there, it was 2 in the morning in the early hours of the June 1st. The officers sounded their car's patrol siren and a few moments later Yorin's dad, Paulus, came out, bleary eyed and looking confused. When the police asked him where his son was, Paulus said Yoran was probably sleeping in the detached apartment behind the house. However, when Paulus called Yorin's cell phone, he said he was out gambling at the Windham Resorts Casino just down the road from the Holiday Inn in so the search party piled into their cars and headed down to the Windham along with palace and the police. But when they got there, Joran was nowhere to be found. Apparently they'd just missed each other. When palace tried his cell again, Yorin said he'd already gone home. Exasperated, the group headed back to the Vandersloot residence. Joran and his friend Deepak Calpo were waiting for them in the driveway, sitting on the hood of Deepak's silver Hana while Beth and George watched. The police questioned Joran. At first, he said he didn't know anything about Natalie, not even her name, but he couldn't lie his way out of this one. Eyewitnesses had seen them together when Joran learned this, he changed his story. He admitted he had met Natalie and her friends at the Excelsior the night before and later joined them at Carlos and Charlie's. He claimed Natalie was drunk and hitting on him. They'd danced together and he'd taken shots with her at the bar. After Carlos and Charlie's closed, Yorin said he, Natalie and the Calpo brothers got into Deepak's car. They drove around the island for a while as Yorin and Natalie fooled around in the back seat. Then, around 2am, Yorin claimed they dropped Natalie off at the Holiday Inn and a security security guard helped her inside. At the search group's insistence, Joran led them to the Holiday Inn and showed them where he had allegedly left Natalie. However, he couldn't find the security guard who'd supposedly helped her.
Dr. Tristan Engels
So I think we can all agree that Joran is not being truthful here, especially those of us who know how this really turns out. And there are a few reasons why your end would seemingly lie about something that could be so easily disproven like this.
Vanessa Richardson
This.
Dr. Tristan Engels
First, it could be an impulsive emotional decision intended to bring him short term relief. Almost like a coping strategy used to escape anxiety, shame or fear. It would give him the temporary relief and sense of control over the situation that he might feel he needs in that moment. Second, it could be a form of denial or self preservation, as if he truly believed that they wouldn't find out. Third, this could be due to disordered thinking. For instance, he may genuinely believe that he could outsmart the police and the authorities in the search group since he has no real history of consequence. And lastly, there are personality traits or even disorders that can explain this as well. Specifically antisocial, narcissistic or borderline traits. And if this was the case, lies would not be reflexive, but rather strategic, especially if we understand the motivation. And given that he has a history of predatory behavior and is already known for his antics around the island island, it's likely more personality based, but certainly it could be a mix of any of these.
Vanessa Richardson
Although it seemed obvious that Joran was lying about what had happened between him and Natalie, there wasn't any evidence that he'd actually hurt her. So the Aruban police had no choice but to let him go. Natalie's family was furious. They were positive that Yorin knew what really happened to their daughter. But if he wouldn't help them find her, they'd do it themselves. Beth and George began organizing more search parties to look for Natalie. Hundreds of tourists and locals volunteered to help. They plastered the island with posters featuring Natalie's photo, asking for information about her disappearance. Over the next several weeks, the Aruban authorities followed dozens of leads. None of them panned out. George even went to the island's Dutch military base and got some of their marines to search the area with helicopters and four wheel drive vehicles. But even they couldn't find any trace of Natalie. Meanwhile, the media was starting to pick up on the case. The story was like cable news catnip. A pretty teenage girl missing under mysterious circumstances in a tropical paradise. Paradise. Soon, hundreds of reporters from all around the world had descended on the island. Beth was doing interviews almost every night to help spread the word. All of a sudden, Aruba was in the spotlight, and not in a good way. With an economy dependent on tourism, Natalie's story was a worst case scenario. Before long, the pressure on the Aruban police to make an arrest became overwhelming. Yorin and the Kalpo brothers were still the prime suspects, but without any solid evidence, the case against them would be flimsy. Under normal circumstances, the police would have taken time to monitor Joran and the Kalpos and wait for them to slip up. But under the onslaught of pressure, the police chief eventually relented and gave the go ahead to arrest them on nothing but suspicious. It was a decision he later regretted.
Dr. Tristan Engels
So whenever anyone is under intense pressure and there is a sense of urgency as well, it narrows the focus and limits a person's ability to think rationally. And in this particular instance, we have a missing person's case with national scrutiny. This could cause officers to disregard or undervalue evidence, or lack thereof, focus intensely on one subject or theory and cause unnecessary delays. Delays? The pressure they face, not just from the public, but from government officials who are worried about the impact on tourism can certainly lead to errors in judgment and even confirmation bias. And that can impair objectivity, cause burnout and lead to rushed decisions.
Vanessa Richardson
On the flip side of the coin, there are many people who say they thrive under pressure. Are there psychological reasons for that?
Dr. Tristan Engels
Yes, kind of similar to the reasons I outlined with Beth, Natalie's mother, who was able to remain calm after getting news that her daughter was missing. It's a mixture of past experiences, coping skills, personality traits, and support or resilience. So those who thrive under pressure have likely been exposed multiple times to high pressure environments. Their bodies may be accustomed to adrenaline, they're more confident in their abilities, and they have a healthier mental framework as a result. And by that I mean rather than Looking at a high pressure environment as a threat, they look at it more like a challenge and that they can draw upon their strengths to overcome.
Vanessa Richardson
Regardless of what motivated the police to arrest Joran, they took the opportunity to question him intensely. It wasn't long before his story about his night with Natalie began to change. Now, Yorin said that he and the Kalpo brothers had not dropped Natalie off at the Holiday Inn like he originally claimed. Instead, the Kalpos had dropped him and Natalie off at the beach a half mile north of the Holiday Inn. He said said that Natalie wanted to have sex, but Yorin refused because he didn't have a condom. According to Yorin, the night ended awkwardly. He said he left Natalie there on the beach alone. The last time he saw her, she was sitting by herself in the sand, staring out at the ocean. The police conducted a thorough search of the beach, but once again there was no trace of Natalie. Yoren and the Kalpo brothers were held in custody for weeks, weeks and questioned almost daily by the Aruban police. And because Natalie was American, the FBI got involved too. But the boys didn't give up any useful information. Finally, on August 31, 2005, 93 days after Natalie went missing and a Reuben judge declared there wasn't sufficient evidence to continue holding them, all three were set free. To the many people following the case, it seemed like Joran Van Der Sloot had just gotten away with murder.
Dr. Tristan Engels
Getting away with a crime has profound psychological effects that go beyond simply feeling relief because it can be reinforcing, increase confidence, and even encourage more offenses. This is especially true for people with antisocial traits, which Joran appears to have because they are driven by impulse, thrill seeking and a desire for dominance or power. It can also desensitize them to empathize any fear of consequences, which may be especially true for him because he's not had any lasting consequences. So as a result, he's going to become increasingly less afraid of any ramifications for his behavior.
Vanessa Richardson
How can holding onto a big secret like the truth about a murder affect someone psychologically?
Dr. Tristan Engels
And that's going to depend on who you're referring to. So if it's your Aun, he's likely unaffected since he already exhibits antisocial traits and appears completely desensitized to consequences like I mentioned. But for for most, it can be psychologically destabilizing. They will be exposed to prolonged stress, especially if they experience fear, guilt, or moral conflict regarding the nature of the crime and the secret they're holding. They will be living in fear of being exposed. And this can cause some fragmentation in their identity because the version everyone sees is not in alignment with the truth. And that can place them into a cognitive dissonance. And that internal conflict can lead to substance abuse and reckless behavior. And eventually they can reach a breaking point where they confess or they just break down entirely.
Vanessa Richardson
Natalie's parents, Beth and George, were still confident Yora knew what happened to Natalie. They continued their campaign to uncover the truth for years. Meanwhile, Yoran escaped any serious repercussions, just as he had since he was a child. A few days after being released from police custody, he flew back to the Netherlands and enrolled in college there. But but the world didn't forget about Natalee holloway, and almost 20 years later, her family would finally get some closure when the full extent of Yoren's crimes were exposed. And it turned out Natalie wasn't his only victim. Thanks so much for listening. Come back next time to learn how Joran van Der Sloot was accused of committing another murder exactly five years to the day after Natalee Holloway disappeared and what he says really happened to Natalie.

For this week's Mantra. I honor my emotions as they guide me through grief. I want to begin by saying this, if it's not already clear. But grief does come in many forms. Our first thought often goes to the grief that, of course, we encounter with the death of a loved one. Because that kind of loss is so profound, leaves so many unanswered questions. You know, where does the love go? How do I live? How can we survive without them? What happens next? All questions we have and many, many more. It's very shocking, it's paralyzing. It defines every other experience we have, at least for a while. But I think grief is also appropriate and also needs to be acknowledged in the face of any loss. Loss of a relationship, a breakup, some might even say loss of a pet. Grief over a time in our lives that we no longer have. It's this intense love mixed with. With pain. And they're in this constant battle. Are we grateful for what's happened, or are we terrified and devastated that it's no longer there? You know, we do sometimes feel so lucky to have the memories and the moments. And then other times, it just feels like this thing is so heavy, we're never going to get out from under it. Such as being human. I think that is the definitive human experience right there. Trying to hold two equally large and heavy truths at once. But yes, there is a hidden beauty in it all. And when we honor our emotions and ride the roller coaster and hold on, just hold on for the dips and the highs, I think we can at least learn something. At most, we feel more in touch with the human experience and like this very deep pool of love that exists in each of us. And the truth is, we need to grieve grief. If someone has passed, if a death has occurred, you need to grieve. Grieving is remembering. Grieving is continuing to hold space for the person and the good feelings. And in a weird way, we really do need that. Grief is definitely hard, but I think society's reaction to it is the main problem, or lack of reaction. That's what makes it so much harder. It often feels like the moment you start grieving, the moment someone passes, the moment that something ends, this, like, timer starts, and you only have a certain amount of time to, like, get over it before it becomes unacceptable. As a society, we are not very good at dealing with grief. We are okay with happiness. We are okay with anger, even grief. No, the moment you say to someone, oh, you know, this person is no longer in my life. My grandfather died. My mother passed away. Oh, you know, I used to have a sister, but she's not here with us anymore. You can see it in someone's eyes. There's like this immediate reaction from most people to like shy away from it. Even though most of us have experienced something similar in our lives, we just can't talk about it. In Western culture in particular, we have such a clinical perspective on death that it makes it really hard to fully feel it. And we also don't have any of like these sacred traditions or the holidays or the celebration celebrations that other cultures do. We don't hold space for those who pass in the same way. You know, in Mexico they have the Day of the Dead. In Japan, when I was there recently, I was in Okinawa. And they literally have people who they hire just to maintain the graveyards and make them into these almost shrines and monuments of remembering. Pitru Paksha is a 16 day Hindu holiday where families pay homage to ancestors who have departed from the material world. There's so many more examples. If you live in like the US or the UK or Australia, or like in a very Western culture, what do we have? We have funerals where everyone wears black and then homemade lasagnas and then nothing. People will show up for the day, but the support slowly fades away. You stay right where they left you. You just stay still in that moment. And there is very limited space or opportunity to continue to celebrate this person. And you know what? Grief is too big to ever be held by just one person. It's a collaborative community emotion. It's something that needs to be spread across multiple souls. I really believe that. And you can't really do that the way you need to in practice in the society we have today. Like, you can't create community around your grief. There's not as many rituals. It's harder to talk about this shared emotion.

Killer Minds: Inside the Minds of Serial Killers & Murderers Episode Summary: MURDEROUS MINDS: The Disappearance of Natalee Holloway Pt. 1 Release Date: May 12, 2025
In the gripping premiere of the MURDEROUS MINDS series, hosts Vanessa Richardson and Dr. Tristan Engels delve into one of true crime’s most enduring mysteries: the disappearance of 18-year-old Natalee Holloway in Aruba and the subsequent accusations against Joran van der Sloot. This episode meticulously unpacks the psychological transformation of Joran from a seemingly well-adjusted youth to a suspected murderer, exploring the intricate factors that may have driven him to commit heinous acts.
Vanessa Richardson opens the episode by painting a picture of Joran van der Sloot's early life, highlighting a seemingly perfect upbringing. Born in the Netherlands, Joran moved to Aruba at the age of four when his father, Paulus, secured a government position. The family enjoyed a comfortable life, with their residence in Neword providing access to private schooling and a local country club.
Despite this idyllic setting, Joran's adolescence was marked by significant behavioral issues. Early onset of puberty—referred to as precocious puberty—played a pivotal role in his psychological development. "Joran became violent toward his brothers, hitting them and at one point destroying Valentin's cell phone," Vanessa narrates (00:06).
Dr. Tristan Engels provides an in-depth analysis of how precocious puberty can alter an adolescent’s psychological landscape. He explains, “During puberty, the adolescent brain undergoes significant changes, particularly in areas responsible for regulating emotions, decision-making, and social understanding (07:01).” The imbalance between the rapidly developing limbic system and the still-maturing prefrontal cortex can lead to increased aggression and impulsive behavior, especially in males experiencing early hormonal surges.
As Joran grew older, his behavioral issues intensified. By age 17, he had become physically imposing—standing at 6 foot 4 inches and muscular—and his aggression became more severe. Incidents included throwing a homeless man off a bridge and pushing a classmate through a glass display case at a movie theater. Despite these violent actions, Joran managed to evade serious consequences, likely aided by his father's connections.
In an attempt to address his escalating behavior, Joran's parents moved him into a detached apartment, granting him more freedom. However, this lack of supervision further enabled his reckless partying and substance abuse, setting the stage for his eventual downfall.
Joran's social circle on Aruba consisted largely of local boys with parents who worked night shifts in hotels and casinos, leaving them unsupervised. By his senior year, Joran was deeply entrenched in a lifestyle of partying, alcohol, and gambling. His affinity for poker not only showcased his strategic mind but also masked his gambling addiction. Dr. Engels explains the addictive nature of gambling: “Gambling activates the brain's reward system, releasing dopamine not just when winning but also during the anticipation of a win (13:53).” This biochemical response, combined with intermittent reinforcement, made it difficult for Joran to curb his addictive behaviors.
On May 29, 2005, 17-year-old Joran and his father were engaged in a poker tournament at the Excelsior Casino in Aruba. Shortly after, Joran continued gambling at a blackjack table where he met Natalee Holloway and her three friends—Ruth, Lee, and Catherine—from Alabama. The group enjoyed a night of carefree partying, culminating in a visit to the popular tourist bar Carlos and Charlie's.
At approximately 1 AM, as the bar closed, Joran reportedly accompanied Natalee and the Kalpo brothers in their car. Witnesses last saw Natalee leaning out the back window of a silver Honda driven by Deepak Kalpo, Joran’s brother, marking the final sighting of her.
Vanessa raises a critical question: “Why would a normally cautious person like Natalie trust a stranger like Joran enough to get in a car with him at this point?” Dr. Engels responds by discussing the evolutionary and psychological factors at play. He notes that humans are biologically wired to trust others who exhibit traits such as competence and integrity. Additionally, prior social interactions and the influence of alcohol can significantly impair judgment, making individuals more susceptible to risky decisions (30:22).
By the morning of May 30, Natalee had not returned to her room, prompting widespread concern. Chaperones initially believed she might have switched rooms, but as hours passed, her absence became undeniable. Beth Holloway, Natalee’s mother, took swift action by chartering a private jet to Aruba alongside her stepfather, George Twitty, and a group of volunteers.
Under immense media scrutiny and pressure to resolve the case swiftly to protect Aruba's tourism-dependent economy, Aruban police faced mounting tension. Despite a lack of concrete evidence, Joran and the Kalpo brothers were arrested based on "suspicious behavior" rather than definitive proof. Dr. Engels analyzes, “Under pressure, people may disregard evidence or focus intensely on a single theory, leading to rushed and possibly flawed decisions (33:28).”
Initially, Joran denied any involvement but soon altered his account under police interrogation. He shifted from claiming Natalee was dropped off at the Holiday Inn to asserting they were left alone on a beach. Dr. Engels discusses potential motivations for Joran's deceit, including denial, desire for control, and possible antisocial personality traits. He states, “Lies in such contexts can be a form of self-preservation or strategic manipulation, especially in individuals with predatory behaviors” (40:12).
Despite the intense search efforts and media frenzy, Natalee was never found, and Joran was released due to insufficient evidence. Dr. Engels highlights the psychological impact of evading justice, noting that “getting away with a crime can reinforce antisocial behaviors, desensitize individuals to consequences, and diminish empathy” (46:15). Joran returned to the Netherlands, enrolling in college and eluding further scrutiny until additional crimes were later uncovered nearly two decades later.
Vanessa concludes the episode by emphasizing the unresolved nature of Natalee Holloway’s disappearance and the psychological complexities surrounding Joran van der Sloot. As the series progresses, listeners can expect a deeper exploration into Joran's subsequent criminal activities and the eventual exposure of his true nature.
Vanessa Richardson (07:01): “Joran became violent toward his brothers, hitting them and at one point destroying Valentin's cell phone.”
Dr. Tristan Engels (07:01): “The adolescent brain undergoes significant changes, particularly in areas responsible for regulating emotions, decision-making, and social understanding.”
Dr. Tristan Engels (13:53): “[Gambling activates the brain's reward system, releasing dopamine not just when winning but also during the anticipation of a win.]”
Dr. Tristan Engels (30:22): “[Natalie's ability to think rationally is diminished. They also spent most of the evening together with both of their respective friend groups, which may have lowered her appraisal of risk.]”
Dr. Tristan Engels (40:12): “[Lies in such contexts can be a form of self-preservation or strategic manipulation, especially in individuals with predatory behaviors.]”
Dr. Tristan Engels (46:15): “[Getting away with a crime can reinforce antisocial behaviors, desensitize individuals to consequences, and diminish empathy.]”
The episode sets the stage for an in-depth psychological analysis of Joran van der Sloot, intertwining true crime storytelling with expert insights. As the hosts unravel the layers of this complex case, listeners are invited to ponder the dark corridors of the human psyche that can lead to unspeakable acts.
