Preliminary results from the medical examiner suggest that Payson Police Sgt. Doug Johnson, 37, died of substantial blockage in one of his coronary arteries.
"Additional tests are being run on toxicology," Police Chief Gordon Gartner said, "but that could take four to six weeks before they get a response on those."
Johnson worked the late shift Thursday, finishing around 2:30 a.m. He went home, and went to bed. By the time his wife, Theresa, checked on him around 9 a.m., he was already dead.
"There was no history of heart disease or anything like that that we know of," Gartner said. "He was a big, healthy guy."
Johnson was an 11-year veteran of the Payson Police Department, and earned the rank of sergeant in May.
He is survived by his wife, Theresa; four children, Jessica O'Donnell, Cody O'Donnell, Dillan Johnson and Sarah Johnson; and his parents, Dennis and Lois Johnson of Payson.
A memorial service will be held at 2 p.m., Wednesday, Aug. 7, at the Payson High School auditorium. Burial will follow at Mountain Meadows Memorial Park.
