On August 10, 2018, at approximately 9:01 AM, CHP motorcycle Officer Kirk Griess, #15810, was on a traffic stop behind an SUV on the right shoulder of westbound I-80, near Manuel Campos Parkway, when for still to be determined reasons, a white Chevrolet pickup truck veered towards his location. The pickup then collided with the CHP motorcycle, Officer Griess, and the SUV.
Sadly, Officer Griess did not survive his injuries. Kirk was a well-respected member of his Vacaville community. He was also a well-loved and respected veteran officer with over 19 years of experience with the California Highway Patrol.
