The Contra Costa County Coroner's Office has identified the driver killed in a solo-vehicle crash in the unincorporated area of Danville on Friday night as 22-year-old Danville resident Austin Nixon.
Nixon was found unresponsive in his vehicle at approximately 11:27 p.m. Friday after his car struck a tree along northbound Camino Tassajara, north of Blackhawk Drive, according to California Highway Patrol Officer Tyler Hahn.
Nixon -- a Monte Vista High School alumnus -- was removed from the vehicle and transported by helicopter to John Muir Medical Center in Walnut Creek, where he eventually died from his injuries, according to Hahn. The driver was the only occupant.
The cause of the crash remains under investigation, and CHP officers are still working to determine if alcohol and or drugs played a role.
