Mystery surrounded the death of a jogger in a Montgomery County park Wednesday night.
A group of friends went for a run in Fort Washington State Park in Whitemarsh Township. At some point, the victim, later identified by the county coroner of Christopher Braun, became separated from the group.
Investigators believe Braun, 25, became disoriented from the heat and fell down a 20-foot ravine. Due to difficult search conditions, it took crews about an hour to find his body near railroad tracks.
A train didn't hit Braun and there were no obvious signs of trauma, police said.
The coroner's office performed an autopsy on the Plymouth Meeting man Thursday morning but said a cause of death pended further testing that could take up to a month the complete.
