Utah County sheriff's detectives do not suspect foul play in the death of an Orem man whose body was found Sunday by motorcyclists in a rugged area west of Lehi.

Detectives identified the man as Rex Chamberlain, 36. A gun was found near Chamberlain's body, but detective Doug Witney said an autopsy performed by the state medical examiner's office showed Chamberlain did not suffer a gunshot wound.Chamberlain was on medication and Witney said detectives believe he had been drinking prior to his death. Chamberlain was last seen Friday and could have died from exposure. Witney said toxicology reports will help determine the exact cause of death.
