Nurse arrested, accused of killing Highland woman to gain access to nonexistent life insurance policy

The doors outside of the Lone Peak Police Department in Highland are pictured Friday, March 21, 2025.A Santaquin nurse is facing multiple felony charges stemming from allegations that she killed a woman whom she was caring for in an effort to obtain her life insurance policy.
According to court documents, Meggan Randall Sundwall, 47, a licensed registered nurse, is accused of intentionally administering insulin to Kacee Lyn Terry, 38, despite Terry being nondiabetic.
“Meggan Randall Sundwall believed she was the beneficiary of a rumored 1.5 million dollar life insurance policy held by Kacee. Detectives were told by Kacee’s family and friends that Meggan had been trying to kill Kacee, with insulin, for years,” court documents allege.
According to Terry’s sister, Kylee Clark, no such life insurance policy existed.
While she declined an interview regarding the matter at this time, Clark did clarify in a Facebook message with the Daily Herald on Friday that her sister never had a life insurance policy. She said information was relayed to Sundwall “multiple times over the years” but the nurse refused to believe it.
Back on Aug. 12, 2024, officers from the Lone Peak Police Department and first responders were called out to a medical emergency at a home in Highland. Terry’s uncle reportedly told police in a 911 call that he found her unconscious and struggling to breathe in a bedroom with Sundwall, court documents said.
When the uncle asked Sundwall how long Terry had been like that, she responded with “a couple of hours,” the probable cause statement said.
During the call with police, the uncle described Terry as having “major, major health issues” and that “it sounds like she’s drowning,” the affidavit states.
Sundwall allegedly told Terry’s uncle that Terry had a “do not resuscitate” medical order and did not want to be placed in a hospital. However, a DNR order was never located by police, nor were any documents that listed Sundwall as Terry’s power of attorney, according to court documents.
While crews were at the home, a paramedic located a diabetic needle, though the documents note that Terry was nondiabetic.
Terry was taken to a hospital in Lehi where her blood sugar was found to be at a dangerously low 14. A blood sugar level below 40 is considered life-threatening.
While at the hospital, Terry’s family told doctors she had suffered terminal cancer but was getting better, court documents noted; however, Terry’s primary doctor revealed she never had cancer.
Terry never regained consciousness and was declared brain dead by doctors. She died three days later on Aug. 15, 2024.
An autopsy performed showed no cancer or any other health problems.
A report from the Office of the Medical Examiner confirmed that the cause of death for Terry was an overdose of Promethazine, probable exogenous insulin and other drugs.
The manner of death was listed as undetermined, court documents stated.
Terry was described in her obituary as a social butterfly during her years attending Lone Peak High School who made many friends, some of whom she stayed close with until she passed.
Prior to Terry’s death, she and Sundwall had also supposedly been friends.
A search of their social media accounts showed they both worked for the same disability service provider, though it’s uncertain if their tenures were at the same time.
During their investigation, detectives reported they found more than 20,000 text messages between the two dating back to 2019.
According to the court documents, some messages allegedly detailed the different ways Sundwall would kill herself if she was Terry and even offered to “help” Terry die.
“They also discuss Meggan’s money problems being solved by Kacee dying and Meggan receiving her life insurance payout,” court documents allege.
Detectives said further evidence revealed Sundwall “continuously searched for Terry’s life insurance policy after her death” through calls and emails, and she deleted more than 900 texts from her phone, which police believe was an effort to hide information from investigators, the affidavit said.
Sundwall was booked into the Utah County Jail on Thursday on suspicion of aggravated murder and obstruction of justice.
As of Friday, Sundwall was being held without bail.
