UTAH COUNTY (ABC4 News)- Utah County Sheriff’s Office is investigating an early morning shooting that left a man and woman dead as a possible accidental shooting and suicide.

The shooting happened just before 12:30 a.m. in Payson Canyon at Maple Bench Campground, according to Utah County Sheriff’s Sgt. Spencer Cannon.

The 911 caller told the dispatcher that a man and woman had been arguing in the area of the campground for several hours when he heard the woman scream and a gunshot.

According to detectives, the man was sitting in a vehicle and the woman was outside talking to him. Then, while the woman was speaking, the man shot himself in the head with a handgun.

Investigators believe the round from that gunshot left the vehicle and hit the woman in the neck.

The man died immediately, according to investigators, but the woman was critically injured. Medical responders with Payson Fire & Rescue, along with AirMed, responded but they were unable to save her.

Investigators say her death appears to have been an accident.

The 911 caller apparently told detectives that he, the woman, and the other man, along with two young girls had been camping together when the shooting happened. Neither the caller nor the two girls were injured.

Utah County Sheriff’s Office later identified the man and the woman who died as 27-year-old Ethan Larry Bertrum Timoko of Orem and 24-year-old Nakylee Hope Marvin of Springville.

The 911 caller told police the two victims had a 5-year-old daughter together. The other child present, a 3-year-old girl, was apparently the daughter of the 911 caller and Marvin.

Both bodies were taken to the Medical Examiner’s Office in Taylorsville.

ABC4 News will update the story when more details become available.
