A former resident of an Alaska assisted living facility has pleaded guilty to murdering a caregiver there, according to the state Department of Law.

Gilbert Nashookpuk entered the plea to a first-degree murder charge on Thursday. In exchange for the plea, the state dismissed a count of second-degree murder against him.

As McKnight’s Senior Living previously reported, Nashookpuk was a resident at Eye to Eye Assisted Living Home when on Nov. 7, 2015, he called the Anchorage Police Department to report that he had “strangled, kicked and punched” to death his caregiver, Glenna Wyllie, 57, because she “had made him angry,” according to the department. Nashookpuk, who was 25 at the time, said he hid Wyllie’s body behind a freezer in the basement of the facility and then left on foot, but he later was taken into custody without incident.

The Alaska Department of Labor and Workforce Development subsequently cited and fined the facility $75,000 for not providing a safe workplace and for not notifying the department’s Alaska Occupational Safety and Health section of Wyllie’s death within eight hours. At the time, Eye to Eye owner Margaret Williams told the Alaska Dispatch News that she did not agree with the claims. “I am not responsible for the death of that woman,” she reportedly told the media outlet.

Nashookpuk is scheduled to be sentenced April 14, according to the Department of Law. He had faced a sentence of 20 to 99 years in prison if convicted of murder in the first degree, but his plea agreement calls for a sentence of 60 years in prison, an additional 20 years of suspended prison time and 10 years of probation. A judge can accept or deny the agreement at the sentencing hearing.
