The body of a Sidney man last seen alive on Sunday was found Tuesday in an area south of the central Montana town of Stanford, according to the Sidney Police Department.
Foul play is not suspected in the death of the man, identified as William Russell Atkinson, according a press release from Sidney Police Lt. Travis Rosaaen.
Rosaaen declined to say more about the cause of death, other than saying Atkinson is not believed to have died of natural causes.
Atkinson was last seen at 11 a.m. Sunday leaving a Sidney gas station. He had reportedly not been in contact with family since April 19, and police were asked to perform a welfare check on him Monday.
Atkinson's cellphone provider, responding to an emergency request made Monday for his cellphone location, showed he was about three miles south of Stanford.
The Judith Basin County Sheriff's Office found Atkinson's body Tuesday in his vehicle "in a remote area," about 15 miles south of Stanford. Rosaaen said it was a wooded, mountainous area.
"Based on the information received by this agency foul play does not appear to be involved," the press release says.
Atkinson was originally from Poplar. The Roosevelt County Sheriff's Office notified Atkinson's family Wednesday.
During the search for Atkinson, law enforcement agencies in Montana and North Dakota were notified he was missing, according to the press release.
