Oregon State Police are investigating the cause of death of a 59-year-old man whose body was found Friday at a Stanfield rest area along Interstate 84.
Police believe the death of Brian L. Henderson, of Perris, Calif., is related to a medical problem, said Lt. Greg Sherman. Henderson was traveling with his elderly mother and the pair had stopped at the rest area about midnight to sleep.
He was found unresponsive in the car at 10:30 a.m., said Sherman. Medics tried to unsuccessfully to resuscitate him.
