A mangled CHP SUV and a twisted and wrecked Cadillac.

It's the aftermath of a horrible crash that killed CHP Officer Andrew Camilleri of Tracy.

“This is not the way we wanted to celebrate Christmas Day. It's definitely not the way we wanted the community to think of the 2017 Christmas Day holiday," said CHP Assistant Chief Ernie Sanchez of the Hayward area's Golden Gate Division.

Camilleri and fellow Officer Jonathan Velasquez were inside their patrol vehicle on the shoulder of southbound I-880 in Hayward close to 11:30 Sunday night.

Ironically, the two officers were on the lookout for drunk drivers when the suspect's vehicle, which the CHP says was driving at a “very high rate of speed” plowed into the rear of the patrol car.

“This person, a 22-year-old from Hayward, chose to drive under the influence of alcohol and also drugs and this needs to stop," added Sanchez.

Both officers were taken to a local hospital and treated for injuries.

Velasquez was treated and released, but Camilleri was pronounced dead.

The suspect, coming home from a party, was also injured and taken to the hospital. Now he will face serious felony charges.

Officer Camilleri got his first taste of what it was like to become a CHP officer working out of the Tracy CHP office and the Explorer program.

“Today he's left behind 3 children, a wife, brothers and sisters. Children that were expecting his father to come home and help open Christmas presents, but instead he chose to work today, to work in the community of Hayward," said Sanchez.

Camilleri had worked just one year and four months since graduating from the CHP Academy.

With a black stripe across officers badges, Governor Brown ordered Capitol Flags flown at half staff in honor of Officer Camilleri's service.
