The county Coroner's Office is listing the death of a 20-year-old Chino man, who was struck by a Amtrak passenger train Sunday in Glamis, as an accident.
County Coroner Investigator Deputy Gary Hayes said based on evidence uncovered during an autopsy Tuesday, the death appears to be accidental rather than a suicide.
Hayes did not release details about the evidence.
Officials will have a toxicology test done to determine whether the man had alcohol or drugs in his system when he died.
The man, Michael Black, had been in the Imperial Sand Dunes Recreation Area with family and friends for the Presidents Day weekend.
