A chilling case out of Utah has ended with a guilty verdict—and a story that sounds more like a crime thriller than real life.
After nearly 10 hours of deliberation, a jury found 48-year-old nurse Meggan Sundwall guilty of aggravated manslaughter in the death of her friend, Kacee Lyn Terry, 38. The verdict, delivered on March 25, caps a disturbing case involving alleged manipulation, fake illnesses, and a deadly dose of insulin.
Prosecutors painted a dark picture in court, accusing Sundwall of deliberately injecting Terry with insulin in a calculated plan to cash in on what she believed was a $1.5 million life insurance policy. According to investigators, the injection left Terry unconscious. She died days later.
The case took an even stranger turn when authorities revealed Terry had never actually been sick.
When first responders arrived at Terry’s home on August 12, 2024, they found her unconscious and struggling to breathe. Sundwall, who was there at the time, told them her friend had terminal cancer and didn’t want to go to the hospital. But investigators later determined Terry had no cancer or any serious illness at all.
An autopsy found she died from a toxic mix of promethazine, insulin, and other drugs.
In court, jurors heard that Terry had spent years convincing people—including her own family—that she was terminally ill. She even sent emotional messages to Sundwall expressing fear about dying, including one chilling plea: “Tell me that I’m not dying.”
Prosecutors argued those messages didn’t justify what happened next.
They presented thousands of texts between the two women, claiming they revealed a disturbing pattern—Sundwall allegedly encouraging Terry to end her life and offering to help. In one message shown in court, prosecutors said Sundwall wrote, “There is nothing left for you here,” and “You have to let go, it is past time.”
In another, she allegedly admitted her own financial struggles, writing, “If you dying would get me out of this mess and darkness I am in, I would take it.”
One of the most shocking pieces of evidence came from a message prosecutors say Sundwall sent before arriving at Terry’s home: “Do you want to take some promethazine when I get there so that you are asleep when this is happening?”
Jurors also heard that Sundwall sat nearby for hours as Terry’s condition worsened. A glucose monitor showed Terry’s blood sugar steadily dropping as it was repeatedly checked, according to testimony.
But the defense pushed back hard, arguing Terry’s death was a suicide. They claimed she had been “begging” for help and had a long history of lying about being terminally ill, suggesting she had both the intent and means to end her own life.
There was one point both sides agreed on: Terry had deceived people about her health for years. But while prosecutors called it a cry for help, the defense described it as manipulation.
In the end, jurors sided with prosecutors.
Sundwall, who had pleaded not guilty, now faces up to 15 years in prison. Sentencing is scheduled for May 4.
