Officer Alvin L. Foss

​Officer Alvin L. Foss, 23, was preparing to go on duty when his revolver fell from its holster, struck the concrete floor, and discharged a round that struck the officer in the head.  The weapon apparently fell on the back of the handle, jarring the firing pin firmly enough to trigger the fatal bullet.

Officer Foss joined the CHP a year earlier and had recently transferred to duty on the San Francisco-Oakland Bay Bridge from Los Angeles.​
