Police have identified the West Linn man who died in his truck after pulling over on Interstate 205 July 7.
Detective Sgt. Kirk Tonkin said the man was Ronald Williams, 49.
'It was a natural death,' Tonkin said.
West Linn Police Sgt. Neil Hennelly said authorities believed the man suffered some sort of medical emergency while on his way to play golf.
'We're still trying to determine what happened, but no foul play is suspected at all,' Hennelly said.
Woodburn resident John Will discovered Williams' body. He was driving to work at Alpine Building Materials in Portland when he spotted Williams' vehicle about 100 yards away from I-205's Willamette viewpoint.
'His blinkers were on,' Will said. 'At that point I hadn't noticed he'd ran into the guardrail.'
Will took the next freeway exit and circled back, parking at the viewpoint before walking to the stopped truck.
He found Williams still buckled into the driver's seat but unresponsive and called 9-1-1.
'I don't know how long he had been there,' Will said. 'It saddens me that nobody else would stop.'
No one stopped to help when passing by Will at the vehicle either.
The car was close to passing traffic - 'There were maybe 3 feet before you'd get hit by a car' if trying to perform CPR on Williams, Will said.
Part of the freeway's northbound section was closed during the initial investigation.
