RICHLAND -- An autopsy on what is believed to be Cody Mason's body did not determine how he died, said John Hansens, Benton County coroner.
Toxicology tests will be done and those results should be available in six to eight weeks, he said.
Dental records will be used to make a definitive identification, although the body is consistent with being Mason, Hansens said.
Mason's girlfriend Cynthia Haley said she found him Sunday in a field behind a shed in the Richland Y. Mason, 26, had been reported missing earlier in the month. He had made suicidal statements before disappearing.
Richland police have said foul play is not suspected.
