An autopsy found that Ashland High School graduate Jesse Golden died Monday after jumping or falling 28 feet from an Interstate 5 overpass near Yoncalla, police said Thursday.

There is no evidence that Golden, a Eugene resident, was struck by a vehicle or that anyone else was involved in his death, according to Oregon State Police. Police are not investigating the death as a crime.

Golden was found dead on the northbound shoulder of the freeway, underneath the Cox Road overpass, at about 3 a.m. Monday.

A commercial truck driver traveling northbound on I-5, near milepost 156, found Golden's body in the shoulder of the freeway, near a green 1994 Honda Accord, registered to a relative of Golden, Hastings said.

The truck driver did not have cell phone service but 10 minutes later he flagged down another motorist who was able to call 9-1-1. OSP troopers from the Roseburg Area Command office and North Douglas Fire Department personnel responded.

Golden graduated from Ashland High School in 2002. He attended the University of Oregon from 2002 to 2009 and studied architecture but did not receive a degree, said Jim Barlow, spokesman for the university.

He worked as a server at the Keystone Café, a vegan restaurant in Eugene, until the time of his death, said server Rachel Whitney.
