Megan Sundwal is a nurse in Utah who has been accused of killing her former roommate, Casey Lynn Terry, for her life insurance policy. In March 2025, Megan was arrested for fatally dosing Casey with insulin. For years, Megan claimed that it was an act of mercy and that she wanted to help her friend, who was dying of cancer, pass away without pain. Megan was also financially struggling. She thought she would be the recipient of Casey's life insurance policy. But there's a twist because Casey didn't have a life insurance policy or cancer. And the craziest thing. Prosecutors have no idea why Casey would have lied about it. This is a case with a ton of layers and it's still playing out. So how did we get here? Let's get into it. Casey was born on May 30, 1986 and grew up in the town of Alpine, Utah. She was described as a social butterfly who was close with her family and loved helping others. So it's no surprise that as an adult she got a job working as a house manager for an organization called Chrysalis, a care facility for physically and developmentally disabled adults. Casey loved her job and would often say it didn't even feel like work because she loved all of the people she worked with so much. She had a lot of love in her heart for everyone she was close to, and that included her roommate, Megan Sundwall. Megan had been a nurse since 2007 and lived in the city of Highland, which is about 30 miles from salt Lake. By all accounts, she was good at her job and loved what she did. Being a nurse meant that she got to help people who really needed it. She and Casey bonded over this and became close friends and roommates. But then Casey got sick. Very sick. Sources say that four or five years before Casey's death, which would be around 2019, she started telling people that she had leukemia and that it was terminal. She ended up having to take a step back from work and all of the things she loved to do. But according to her sister, Casey made it clear that she wanted to fight her cancer even as her symptoms got worse. Her sister described sitting with her for hours as she threw up and said she personally took Casey to doctors appointments and picked up medication for her. It has not been Specified what kind of appointments they were, but it likely wasn't chemo or radiation, because, as we know, Casey did not have cancer. However, it was enough to convince her friends and family that she was really sick. And through all of her health struggles, Megan was by her side to help her and give her guidance, but not in the way you'd expect. As far back as 2019, Megan started texting Casey strange things. According to court documents, Megan mused about how she would kill herself if she was in Casey's position. One way she theorized she would do it was with insulin, because as a nurse, it would be easy to get her hands on. It didn't seem like Casey wanted to die, but Megan couldn't let go of the idea. She sent thousands of texts urging her to go through with the plan. One message said, you have to let go. It's past time. I can give you insulin over and over until it works. I will come help you. Another text read, someone should probably be me. Should stay with you and continue to give you doses so it will actually stay low and you can pass. Casey was put off by Megan's constant pushing and started getting unnerved After Megan apparently brought insulin home from work with her. Casey complained to her sister about Megan's behavior, and her sister jumped into action. She moved Casey out of her apartment with Megan and moved her into their grandfather's home. But that didn't appear to stop Megan's insistence that Casey needed to end her life. She was relentless, and it seems like there might have been another reason why. Casey apparently told Megan that she had taken out a $1.5 million life insurance policy and named Megan as the beneficiary. Megan reportedly double checked with Casey about the status of her life insurance policy often and asked if the policy was in danger of expiring. But Casey told her not to worry. She was fully paid up on it. It turns out Megan and her husband were struggling to pay the bills. They had young kids and had just bought a home that they had to readjust the mortgage on Twice in just a year and a half. Megan complained a lot about her money troubles to Casey. She described her financial situation as dismal. In one message, she wrote, if you dying would get me out of this mess and darkness I am in now, I would take it an absolutely wild thing to say to anyone dying of cancer, let alone one of your alleged closest friends. But even though Casey's cancer was supposedly terminal, she maintained her positive outlook on life. She cared enough to fix a knee issue with a full knee replacement surgery and had a dog she loved. Her family says she was focused on getting better and fully living her life bit by bit. But even that didn't seem to stop Megan thinking she needed to die. On August 12, 2024, Megan allegedly decided to follow through on the plan she had created for Casey. And it appears that she had told Casey because before she left for Casey's house, she texted her quote, do you want to take some promethazine when I get there so that you are asleep when this is happening? Megan arrived at Casey's house around 10am that day and according to prosecutors, she injected Casey with the promethazine before administering a fatal dose of insulin. She continued monitoring Casey's blood sugar levels as they plummeted below the safe levels even after Casey became unconscious. Megan stayed with Casey for hours as her condition worsened. Around 9pm that night, Casey's uncle came by and found her unresponsive. With Megan by her side, he called 911 telling them that his niece with major, major health problems wasn't waking up and that it sounded like she was drowning. When EMTs arrived on the scene, Megan told them that she held power of attorney for Casey and that Casey had a do not Resuscitate order or dnr. Casey was rushed to the hospital and when she got there, the doctors tried to find her dnr, but it didn't exist. Plus, Megan didn't have any power of attorney like she had claimed. This was the authorities first indication that that things may not have been what they seemed and it was far from the last.

When Casey Lind Terry arrived at the hospital on August 12, 2024, her blood sugar levels were at 14, which is shockingly low. Anything lower than 40 is potentially lethal. Doctors and investigators had a lot of questions about how this was possible. A forensic pathologist was interviewed and said that the only way this could have happened to Casey was was through exogenous insulin, meaning someone had injected her with it. This made sense considering investigators discovered both a diabetic needle and a blood glucose monitor at Casey's home, even though she wasn't diabetic. When investigators interviewed Casey's sister, she told them about Megan's many, many texts, trying to talk Casey into assisted suicide using insulin. But her sister made it very clear that Casey didn't want to die. All of this evidence, plus her strange behavior at Casey's house, made Megan their prime suspect. Megan was likely worried that things didn't look good for her because she went into her phone and started deleting any text between the two of them that made her look guilty. Ultimately, she deleted over 900 messages. But that didn't even put a dent into the five years worth of conversations she she had with Casey about insulin. Meanwhile, Casey was fading fast. A few days after she was brought in, the doctors declared her brain dead, and Casey's sister had to make the horrible decision to remove her from life support. Sadly, on August 15, 2024, Casey Lynteri died. And while her family mourned, Megan Sundwal was busy trying to dig up any documentation about Casey's life insurance policy. Megan allegedly turned to the police for help. She told them about the policy and asked if they could help her find any papers in Casey's room. But still, nothing turned up. Megan eventually got in touch with the company behind the policy, and that's when she learned it had never even existed. And when she asked the police to help her track down the life insurance policy, she had tipped them off about her motive. A little while later, investigators got a search warrant to go through Megan's phone. When they confronted her about the deleted text messages, she came clean about deleting them. She said she didn't want it to look like what she was being accused of. Investigators already had plenty of compelling evidence against Megan, though She had the means, the motive, and the opportunity to kill Casey. But then a twist in the case stunned everyone, especially Casey's family. When the medical examiner's office performed Casey's autopsy, they found evidence of the insulin, promethazine, which is the sedative Megan had texted her about, and traces of other drugs. But the one thing they didn't find was any sign of cancer in her body. And when investigators followed up with Casey's primary physician, it was confirmed that she was totally healthy and had been the entire time. Casey never had cancer to begin with. This came as a huge shock to Casey's sister, who had been there every step of the way through her treatment. Not only that, it made Megan suspected actions look even worse. She had apparently given insulin to someone who is perfectly healthy and did it for money that never even existed. This, of course, led to more scrutiny about Megan's actions before Casey's death. Considering her prolonged gaslighting to try and convince Casey to die by suicide, some people started to suggest that Megan was the one responsible for convincing Casey she had cancer in the first place. And it's important to note the media picked up on this, too. If you Google this case, a lot of articles will mention that Megan is the one who made Casey think she had leukemia. But it turns out that this wasn't the case. When investigators went through Casey's messages, they found that she had been the one to tell her family and friends that she had terminal cancer. She kept up the ruse for years, going to doctor's appointments and getting medication. Or at least she did a good enough job of making her loved ones think she was. So Casey hadn't just lied about the life insurance policy. She had lied about the entire cancer diagnosis. And it seemed like Megan actually believed Casey was very sick. Which still does not excuse Megan's alleged actions. No one, especially a nurse, should react to a friend's cancer diagnosis by planning how to assist in their death, even if it means a massive payout. But it raises questions about Casey's mindset. Why did she convince her loved ones that she had cancer even though she was totally healthy? Why did she tell Megan that she had made her the beneficiary of a $1.5 million life insurance policy after learning about her financial troubles? Again, none of this makes any of Megan's alleged actions okay, but it adds a mystifying element to this case, one that Casey's family is still struggling with. However, regardless of what Casey's motivations were police were certain that someone had wanted her dead. And they believed that someone was Megan Sundwal.

On March 20, 2025, seven months after Casey Lynn Terry's death, Megan Sundwalt was arrested and charged with aggravated murder and and obstruction of justice for killing her friend and former roommate. At her first hearing, prosecutors pointed to Megan's deletion of hundreds of texts as proof she couldn't be trusted. Deputy attorney Lauren Hunt had said Megan had, quote, attempted to interfere with this very investigation. Her history of deceit, her financial desperation and her manipulative conduct makes her both a profound flight risk and ongoing danger to the community. In the state of Utah, the aggravated murder charge has the potential to carry the death penalty. But after consulting with Casey's family, prosecutors decided to only pursue a punishment of life in prison without possibility of parole. Meanwhile, Megan's community rallied around her. Each preliminary hearing was packed with people from Megan's life, family, friends and former patients. Additionally, they wrote hundreds of letters attesting to Megan's character. They testified that she would never do anything to harm someone, especially someone she knew so well. Megan's attorney highlighted her lack of criminal record and the need for her to be present in her children's lives as reasons she should be allowed to post bail, and also pointed out that the prosecution had mentioned some recorded jailhouse calls in their statements without notifying him. He criticized the prosecution's tactics as a dragnet against Megan and said that they were doing it to try and paint her in a worse light. Despite these arguments, Last month, on September 18, 2025, Judge Sean Patterson sided with the prosecution and denied Megan's bail as of this recording. That's where the story ends for now, at least until the trial, which hasn't been scheduled yet. And we should be learning more with every court appearance between now and then. As the case against Megan comes into focus, there is there should be more clarity about her, about Casey, and about all the pieces that still don't add up. We'll be keeping a close eye on this one and hopefully we'll get more answers to the lingering questions here. And as always, we'll be sure to bring you all of the major updates.
