A 24-year-old Antioch woman died in a morning crash on Highway 24 Wednesday despite an intense effort by firefighters to resuscitate her as commute traffic crawled by.
California Highway Patrol investigators said Trista Allen was westbound on Highway 24 just west of the Acalanes offramp when her Nissan Altima abruptly strayed out of its lane and struck another vehicle before veering back into the center median and coming to rest.
Witnesses said the 8:45 a.m. incident triggered a near collision with other cars and was originally believed to have brought down a passing motorcyclist, which proved not to be the case.
Firefighters initiated life-saving measures for Allen, who was unconscious and unresponsive upon their arrival. She was transported by ambulance to John Muir Medical Center in Walnut Creek, according to the CHP, and shortly after arriving there was pronounced deceased due to apparent prior medical issues unrelated to the collision.
There are no outstanding vehicles and alcohol or drugs do no appear to be a factor in this collision. If anyone witnessed this collision or can provide further information, please contact Contra Costa CHP and Officer Adolphson.
