One person was killed in a traffic collision on state Highway 4 in Antioch Friday afternoon.
The collision occurred at 1:38 p.m. on westbound state Highway 4 east of Hillcrest Avenue, according to the California Highway Patrol. Investigators said four vehicles were involved in the collision.
According to police, the driver of a white Infiniti G37 was traveling between a Chevrolet Tahoe and a semi truck when the Infiniti collided with the Chevrolet.
The Tahoe driver lost control of his vehicle, crashed into a guardrail, was struck by the semi truck and was then struck by a Toyota Corolla.
The driver in the Tahoe, a 56-year-old Discovery Bay man, suffered fatal injuries and was pronounced deceased at the scene, according to the CHP. None of the other people involved in the collision were transported to the hospital.
Investigators said it does not appear alcohol or drugs played a factor in the collision. The CHP asks that anyone who witnessed the collision or events leading up to it to contact the Contra Costa division at (925) 646-4980 if they have not yet spoken to CHP,
The Contra Costa County Sheriff’s Coroners Office will later release the man’s identity.
