Maine State Police have identified the man who they say died when his pickup truck caught fire in Richmond early Saturday morning as Jerry Kiesow, 44, of Richmond, according to a news release Sunday afternoon.

Kiesow lived on 45 Bettle Road and the State Medical Examiner’s Office is now trying to determine the cause of his death, said Steve McCausland, spokesman for the Maine Department of Public Safety.

Richmond firefighters and police responded at 3:30 a.m. Saturday to a report about the fire, which occurred on an unpaved section of Lincoln Street, and discovered the remains inside the still-burning vehicle.

On Saturday, Richmond Police Chief Scott MacMaster said “a lot of evidence” in the case was “pointing towards” Kiesow’s death being a suicide. There’s “nothing that leads us to believe it was anything other than that,” he said.

State Police and the Office of Maine State Fire Marshal are both investigating the origins of the fire.

“At this point we have concluded it is an isolated incident,” MacMaster said on Saturday morning. “There is no threat to public safety.”
