On August 12, 2024, 38-year-old Kacee Terry spent the day with her best friend at her home in Highland, Utah. By that evening, Kacee was unconscious. When family members discovered her struggling to breathe, three people sat quietly in the room beside her, and one woman insisted no one should call 911. Days later, Kacee was dead.

What investigators uncovered next would transform this case into one of the most shocking and complicated criminal investigations we’ve ever covered. In this episode, Ashley Flowers and Brit Prawat examine thousands of pages of court records, trial testimony, digital evidence, and more than 28,000 text messages exchanged between Kacee Terry and her best friend, Meggan Sundwall. What began as the investigation into a mysterious death ultimately revealed years of deception, manipulation, fabricated illnesses, and a friendship built on lies.

You’ll hear about the events of August 12, 2024, that led to Kacee Terry’s hospitalization, the discovery that Kacee’s blood sugar had dropped to life-threatening levels, the insulin evidence investigators say became central to the case, the digital trail hidden inside more than 28,000 text messages, the shocking truth investigators uncovered about Kacee’s medical history, the role a supposed $1.5 million life insurance policy played in the investigation, and the courtroom battle over who was truly in control during Kacee’s final hours

This episode also explores the complicated relationship between Kacee Terry and Meggan Sundwall, how investigators reconstructed the final day through phones, messages, and digital evidence, the challenges prosecutors faced proving criminal intent, and why this case left jurors with difficult questions about manipulation, influence, and responsibility. Following trial, Meggan Sundwall was found guilty of manslaughter and obstruction of justice. -------- Are you apart of Ashley's Summer Watch Challenge?
