Woman Suffers Medical Crisis While On Westbound Highway 24 In Lafayette Wednesday


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.

  1. Can’t imagine. The only thing worse than passing out while driving would be having it happen whilst flying. Thoughts and best wishes for her.

  2. caught in this but it looks like it is clearing. There was a motorcycle there but you say it didn’t crash?

    • Hey, Adam… it is clearing from what we can tell. The woman either brushed the cyclist when she passed out or a cyclist stopped to help (which is way cool if it went down that way.) People see car/motorcycle and think crash… this was a medical emergency.
