Officer Kirk Griess, 46, had pulled over Jaime Bueza Manuel, 49 of Vallejo, when a vehicle driven by Walker struck and killed both of them.

Walker faces two charges of gross vehicular manslaughter and one count of reckless driving resulting in a fatality.

“This is something that could have been stopped,” said CHP Capt. Mark Headrick. “It was a combination of reckless driving and distracted driving that took the lives of Officer Griess and Mr. Manuel and that is something that we are deeply saddened about.”

Headrick drove home how easily the tragedy could have been avoided.

“We want the message to be sent that your actions have consequences. That answering a phone or sending or answering a text can result in the tragic consequences that we witnessed last week,” he said. “And lives can be unalterably changed because of those actions.”
