Santaquin woman charged with aggravated murder in insulin death of her friend

HIGHLAND — Criminal charges have now been filed against a Santaquin woman accused of killing her friend to get her million dollar life insurance policy — only to find out that she didn’t have a policy.

Meggan Randall Sundwall, 47, is charged in 4th District Court with aggravated murder, a capital offense, and obstruction of justice, a second-degree felony. According to charging documents, “conviction of this offense may carry the death penalty.”

On Aug. 12, 2024, Kacee Lyn Terry, 38, was found unconscious in her basement bedroom in Highland. Her blood-sugar level had plummeted and could not be stabilized, according to charging documents.

Sundwall, who used to live with Terry, was also in the room. Sundwall’s parents had arrived at her request to give Terry a religious “blessing of release,” the charges state. Sundwall allegedly told another relative not to call an ambulance because Terry had a “do not resuscitate” medical order and Sundwall “had her power of attorney.”

But police investigating Terry’s death say that “no documentation of either was ever located.” Furthermore, detectives learned that Terry “was not diabetic and had no reason to have a glucose monitor or to take insulin,” according to the charges.

As the investigation continued, police learned that Terry had told Sundwell “numerous times over the years that (Sundwall) was Terry’s life insurance beneficiary of a policy worth over a million dollars,” the charges state.

The investigation also revealed that Sundwall and Terry “had discussed using insulin to cause death many times since 2020, with (Sundwall) consistently urging (Terry) to do it and (Terry) regularly pretending that she had done so, but claiming it ‘didn’t work.'”

Terry’s sister told police that Terry “had been diagnosed with leukemia several years earlier” while Sundwall and Terry were roommates, according to a series of search warrant affidavits filed by police during their investigation in 2024. “She stated that she moved Kacee out of the shared apartment and into her grandfather’s house … due to Kacee complaining about Meggan bringing insulin home and trying to talk Kacee into treatments to help end her suffering.”

Her sister told doctors at the hospital that Terry “had terminal cancer for four to five years,” according to a police booking affidavit. But doctors, “while getting information about (Terry’s) medical history from her primary care physician they were told that she never had cancer. The autopsy performed revealed no cancer and no health problems.” Court records do not indicate why Terry may have told her sister she had cancer.

Sundwall sent several text messages over years to Terry encouraging her to “kill herself by insulin overdose,” such as: “You have to let go! It is past time!” and “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” and “I can give you insulin over and over until it works … I will come and help you,” according to charging documents.
