A driver was killed along Interstate 580 after losing control on the Altamont Pass and rolling approximately 300 feet down an embankment on Easter Sunday, according to the California Highway Patrol.

The Alameda County Coroner's Bureau identified the victim as 62-year-old Patrick Doherty. His city of residence was still in the process of being confirmed, a coroner's representative said Monday.

The crash occurred just before 11:15 a.m. Sunday when a white pickup truck heading eastbound on I-580 east of Flynn Road North at approximately 60 mph toward increasing traffic made an abrupt turn to the right and went off the roadway for unknown reasons, according to CHP Officer Tyler Hahn.

The truck traveled out-of-control down an embankment, rolling several times before coming to rest approximately 300 feet down the hill, according to Hahn.

Responding CHP-Dublin officers climbed down the embankment to try to render aid, but they could not immediately access the driver because the truck's cab was crushed and the man -- later identified as Doherty -- was trapped. He was the only occupant, according to Hahn.

Alameda County Fire personnel soon arrived and removed the man using the Jaws of Life, according to Hahn. A Contra Costa County Fire and Rescue helicopter landed in a dirt turnout next to the freeway to assist as well.

The cause of the fatal crash remains under investigation, according to Hahn. Any potential witnesses can contact the CHP Dublin office at 925-828-0466.
