On the Evening of Saturday, June 28, 2014, 21 year old John Corwin was sitting at his apartment inside the Marine Corps Air Ground Combat Center Military base in Twentynine Palms, California. Racking his brain, he had no idea where his 19 year old wife Erin was. And it was getting later and later. The last time they'd spoken was around 7am that morning when Erin left their place to visit Joshua Tree National Park. Her plan was to take some time to herself and scout out scenic areas in the park that she and her mother Lore would visit. When Lore flew in from Tennessee for Erin's birthday, which was on July 15, when they'd last spoken, Erin had told John she would be home by 4pm but that time had come and gone and Erin had still not called, texted or otherwise contacted her husband. So Starting shortly after 4pm, John dialed his wife's cell phone a few times, but each attempt went straight to voicemail. Not wanting to think the worst, John convinced himself that Aaron was probably just at a friend's house or had bad cell phone reception. But as the hours ticked by, his resolve waned. It was unlike Aaron to not pick up the phone. So by midnight, fraught with worry and waiting desperately for her to call him, he dialed her a few dozen times, but once again was unsuccessful at reaching her. By sunrise the following morning, Sunday, June 29, he knew something was very wrong. So he got in touch with the San Bernardino County Sheriff's Department and reported Aaron missing. He also called Lore, Aaron's mom, and explained what was going on. The last time Lore had spoken with Erin was on Thursday, June 26, two days before she disappeared. During that phone call, the two women discussed Laura's upcoming trip to California and ironed out some of the details of their trip to Joshua Tree. And they also had plans to go to a zoo and theme park in San Diego. Before hanging up the phone, Erin had told her mom she loved her, and Laura responded in kind. Not long after John made the official missing persons report, two officials came out to the military base and met with him at his apartment. Those investigators took down basic information about what Erin looked like when she'd last been seen, and Contact information for her family members and friends who lived in Tennessee. The deputies also canvassed the Corwin's apartment building and talked with neighbors to see if anyone had heard from or seen Aaron, but no one claimed to have. In particular, they chatted with a man named Chris Lee, who lived in the unit next to John and Aaron with his wife Nicole and a young daughter. Chris answered authorities questions but wasn't much help because he claimed he didn't really know Erin well and hadn't noticed her leave or come home recently. However, when the investigators spoke with a couple who lived in an apartment beneath the Corwins and Lees, they learned something totally different. A woman in that unit told police that not only did Chris know the Corwins well, he'd had an extramarital affair with Aaron several months prior, which had ended badly and taken a toll on the friendships between everyone in the building. Now, this revelation immediately piqued the authorities suspicions because it completely contradicted what Chris Lee had just communicated to them minutes earlier. But when they walked back upstairs to speak with him to sort out the discrepancy, he was nowhere to be found. He'd left his family's apartment abruptly while detectives attempted to track him down. The sheriff's department launched a full scale search for Aaron in and around the national park. They utilized ground teams as well as an aircraft overhead to cover as much of the desert as possible. John jumped in as well and wrangled several marines he knew to help search for his missing wife. It seemed that everyone's initial assumption was that Erin had likely gotten lost or become dehydrated. It was a common occurrence, especially during the summer months, so time was of the essence to locate her and get her some help. Meanwhile, in Tennessee, Erin's mom, Laur, was growing more and more concerned about her daughter's well being. Flurries of messages and phone calls steadily flew between her family members and people in their community who were worried about what was going on. To help get the word out and manage the influx of support, Erin's loved ones created a Facebook page titled Locate Erin as a means to update folks on the search for her, as well as drive tips and information to California authorities. The physical description that investigators put out about Erin was that she was white, weighed 120 pounds, was 5ft 2 inches tall, and had brown hair and blue eyes. The vehicle she and John owned, which authorities had established was missing from the couple's apartment, was a blue 2013 Toyota Corolla. Around noon that same day, authorities who'd remained at the Corwin's apartment complex, spotted Chris Lee returning and immediately confronted him about his prior affair with Aaron and the fact that he'd failed to reveal that information when they first spoke with him. In a taped statement taken at that time, Chris admitted to having had an affair with Aaron several months earlier, but claimed it was over and the only reason he'd gotten involved with her was because he was dealing with depression and she'd manipulated him by lying about being a victim of spousal abuse. Investigators weren't sure what to make of Kris claims Since Aaron wasn't around to give her side of the story. So for the time being, they kept their eye on him and continued to look for her. At that point in time, they didn't have any evidence that the couple's illicit affair was connected to her disappearance. And furthermore, they knew that Chris wasn't the only guy in the apartment building that would have been affected by that relationship. John Corwin, Aaron's husband, was someone authorities needed to take a harder look at, as well as when investigators questioned him one on one, John answered their questions to the best of his ability. But unfortunately, he didn't have a rock solid alibi for Saturday the 28th. He'd been home by himself all day while Aaron was out. He claimed he hadn't left the military base at any point and had no idea where exactly in the national park his wife had planned to go. His phone data and computer records later confirmed his account of not having been off base, and that, in tandem with the fact that he passed a polygraph test after 20 total hours of being interviewed, seemed to convince authorities he was telling the truth. The next day, Monday, June 30, investigators discovered a clue that was both useful but also deep in the mystery. An area water district employee found Aaron's blue Toyota Corolla parked about five miles outside the boundary of the national park. It was locked, covered in dust, and pulled off to the side of the road. The location was noteworthy because it was only a couple miles away from the back gate of the military base. A local resident quickly came forward and told police she noticed the vehicle parked on the side of the road on the morning of the 28th, and she had photos to prove it. This witness said the only reason she grabbed her phone and snapped the pictures on Saturday morning was because a random car being parked in such a remote area felt oddly out of place to her. So much so, she felt like she needed to document it. She gave her pictures to detectives, and that was all the proof they needed to feel confident that something had likely happened to Aaron. And shortly after she left the military base on the morning of the 28th, while processing the car, investigators noticed there was a single set of shoeprints that led away from the driver's side and disappeared next to a set of tire tracks that didn't belong to Aaron's vehicle. That clue suggested she'd likely gotten into another car. But whose car? And why? Authorities weren't sure, but they had their suspicions. The next day, July 1, the sheriff's office obtained search warrants for Chris Lee's Jeep and the Lee's in Corwin's apartments. They didn't find anything in John and Aaron's place that suggested foul play, but they did discover a sticky note on Aaron's laptop with the name of an apartment complex on it that an investigator later determined was located in Anchorage, Alaska. They also found a love note in her jewelry box, which John confirmed wasn't from him, which implied someone else had held deep feelings for Aaron. And detectives suspected that someone else was Chris Lee. Inside his and Nicole's apartment, investigators found a scope for a.22 caliber Winchester rifle, but the gun was nowhere to be found. They also knew Chris owned a machete, various knives, a blowgun, and a.357 revolver. Following the search of the apartments and the seizures of Chris Jeep, he agreed to speak with investigators at the sheriff's department. And it was that conversation, combined with what they'd already learned from speaking with Aaron's family and friends, that gave investigators a much fuller picture of who the Corwin's and Lee's were and what the heck was really going on. John and Aaron had grown up in Tennessee and known one another since they were kids. In their teens, they reconnected and began dating. John was a little more than one year older than Aaron, and after graduating high school, he'd enlisted in the Marines. Despite doing long distance while he was in basic training, their relationship blossomed and moved quickly. About two weeks before Aaron's 18th birthday, they got engaged. A few months after that, in early November 2012, they eloped in Las Vegas after attending a Marine Corps ball there together. For most of their engagement and the start of their marriage, they'd lived long distance with him either overseas or in California and her in Tennessee. However, in late September 2013, they'd managed to secure base housing, and so Erin officially moved into her apartment in Twentynine Palms. At that time, John was deployed, but later joined his wife. By the end of 2013, Shanna Hogan explained in her book that it wasn't uncommon for young couples like the Corwins, who were living on base. To quickly find community with other Marine families. John and Erin started hanging out with the Lees, who lived in the unit directly next to them. And their friend group only got bigger from there. It included another couple with young kids who lived one floor below them. All of the husbands were Marines and grew close and the wives bonded as well. They regularly leaned on one another for childcare and handling bouts of loneliness whenever their husbands were working. A few months into their new life, though, things in the Corwins marriage had begun to show signs of cracking. The couple burned through money quickly and as a result, they built up significant credit card debt. So to help supplement their income, Erin had gotten a job at a tractor supply store near Twentynine Palms. But that gig didn't last long because she didn't like the 45 minute commute. And some health issues had prevented her from working as many shifts as she hoped to. As an alternative source of income, she began babysitting for women on base who needed childcare. And among those families were the lees. By early February 2014, Erin and John's marriage was in a bad spot. They'd experienced a heartbreaking pregnancy loss and continued to bicker over their finances. Each of them handled Erin's miscarriage differently, with John bottling up his emotions and Erin confiding in other people. Her mom, Lor, told me that during her conversations with Erin throughout this time, she never sensed that anything was wrong. She believes Erin felt like she needed to be strong and not allow too many people to see her in pain. Also, unbeknownst to lore, after Aaron experienced a miscarriage, she began hanging out more and more, one on one with Chris Lee. And what began as a harmless friendship quickly turned into a full blown extramarital affair on both their parts. People in their lives eventually picked up on signs that something seemed to be going on between the two of them. They were just getting a little too close, stealing quiet moments alone, were caught kissing when they thought no one was watching, those sorts of things. All the while, neither Aaron's husband John, nor Chris wife Nicole knew what was up. Chris and Nicole were originally from Alaska, but had been living in Twentynine Palms for several years before the Corwins showed up. While dating in high school, they'd found out they were pregnant with their daughter. And a few months after she was born, Chris had enlisted in the Marines thanks to a deferral program. He didn't actually have to go to boot camp though, until six months later, in early 2009, Chris was considered well suited for military service. He was the second eldest of four siblings and had grown up with a love of the outdoors. He'd learned from a young age how to proficiently hunt, fish and camp. And over the years, he'd developed an interest in sharp weapons, including knives, throwing stars and swords. And this hobby didn't go unnoticed by people in the Lees and Corwin's friend group. A downstairs neighbor who would regularly watch Kristen, Nicole's daughter, told author Shanna Hogan that Chris had an unusual obsession with weapons and death in general. His personality was what she described as immature. She said he would frequently talk about killing people or he'd crack jokes referring to killing people. Authorities later learned from speaking with personnel on base that Chris had been disciplined for carelessly using some of the military's rocket launchers and guns. Folks who knew him had also mentioned that he often went to the desert and acted recklessly, which included blowing things up, shooting guns, going off roading, and having bonfires. Publicly, though, or at least in his military service record, Chris was viewed as an upstanding Marine. He'd been deployed to Afghanistan for a period of time between 2012 and 2013 and served honorably. He'd even been given several service awards, including a good Conduct medal. Privately, similar to what had been happening with the Corwins, his marriage with Nicole was less than ideal. According to Shanna Hogan's book, the couple often butted heads over their finances and keeping their house in order. Friends often noticed that their place was unkempt, and they didn't seem to have much regard for tidiness or cleanliness. The Lees had also experienced a pregnancy loss while living on base, which only made their relationship more strained. To help deal with the aftermath of that loss, Nicole had found comfort in volunteering at a horse rescue near Twentynine Palms. And though Chris volunteered at that same place sometimes, he hadn't found as many meaningful outlets to tend to his mental health struggles. After he'd returned from deployment and experienced the pregnancy loss with his wife, he'd become withdrawn, apathetic, and wasn't performing as well at work. He'd also developed a short temper, and that only made tensions worse between him and his wife. According to what Chris told investigators, his affair with Aaron was his escape from reality. Author Shanna Hogan wrote in her book that Erin had apparently been experiencing something similar. She regularly texted a good friend of hers in Tennessee that she'd become completely infatuated with Chris, to the point where she was Even researching Alaska online because she genuinely thought she might move there with him. So that probably explains the sticky note authorities eventually found on her laptop with the name of that Anchorage, Alaska apartment complex on it. On Chris side of the equation, though, unbeknownst to Aaron, he'd resolved himself to keep his nuclear family, meaning Nicole and their daughter together. Divorce wasn't something he wanted, and the possibility of losing regular access to his daughter was completely out of the question for him. But that nearly happened because it only took a few weeks before his wife got suspicious of him and eventually got into his phone's SIM card and read all of his many texts with Aaron. It was clear at that moment that the jig was up. The fallout of the affair resulted in Chris and Nicole having a huge blow up argument. And later, during a get together with friends, Nicole revealed to John that Aaron had been cheating on him with Chris. That interaction had led to a confrontation between Nicole and Aaron, which ultimately ended with John and Aaron returning to their apartment with a neighbor and discussing the whole thing in private. John told producers with Dateline that discovering his wife's infidelity broke his heart, but he was committed to making their marriage work to try and repair the damage in his family. Chris Lee claimed to his wife that he and Aaron had never actually had sex. They'd only kissed a few times. He told his wife that his relationship with Aaron meant nothing to him and it was just something he'd done to help him cope with his depression. After returning from deployment, he assured Nicole that the affair would end and he begged her for a second chance at keeping their family whole, and that seemed to be that. However, on June 22, one week before Erin disappeared, she and John had found out that she was pregnant again. According to doctors at the hospital they went to, she was about three weeks along when they discovered she was expecting. The news was a bit of a surprise to the couple considering the fact that they'd been through so much after the whole affair drama and hadn't found much time to be intimate. But because it seemed that all of that was in the past by the time June came along, John was actually kind of excited to learn that he and his wife were going to be parents. Erin, on the other hand, was much more reserved in her excitement. Unlike the first time they'd found out they were going to have a baby, she didn't post about her pregnancy online or tell many people, not even her own mother lore. The only person Erin confided in about the pregnancy was her friend Jesse in Tennessee. And that's because secretly, Erin suspected the baby wasn't John's.
