PITTSBURG — An Antioch police officer and at least three others were hospitalized after a person in a carjacked vehicle opened fire on the officer following a pursuit Wednesday evening, authorities said.

Antioch police said one of their officers spotted a black BMW that was reported carjacked in Bay Point just before 6 p.m. The officer located the car, being driven by a Hispanic male, in the area of West 10th Street and Verne Roberts Circle. The BMW sped away and the officer gave chase.

The pursuit ended at 6:12 p.m. when the suspect crashed the BMW at the intersection of East Leland and Loveridge roads, triggering a multivehicle pileup.

As officers approached the BMW, a person in the suspect vehicle began shooting and struck one officer, police said. Police returned fire, and the suspect, who was not hit, surrendered.

The injured officer was transported to a hospital after the shooting, said Pittsburg police Capt. Ron Raman. Antioch police confirmed the officer was injured but that he was treated at the hospital and released.

Neither the suspect nor injured officer were publicly identified by police late Wednesday.

Both Antioch and Pittsburg police responded to the scene. Two bullet holes were visible in the windshield of an Antioch patrol car.

Seven vehicles were involved in the crash at the intersection, Contra Costa County Fire Marshal Robert Marshall said.

The extent of the victims’ injuries was unknown.

The intersection remained closed as of 9 p.m., with at least 10 police vehicles still working the scene, their emergency lights flashing. Yellow evidence markers were scattered throughout the scene, including one spot that appeared to be a car part or bumper in the intersection.

Renee Harrington, of Antioch, was working at her job at a Shell gas station convenience store at the corner of Loveridge and East Leland roads when she heard the crash. Right afterward, she says she heard “pop, pop, pop” and more popping sounds followed. Alone at the time, she immediately ran to the front of the store and locked the bulletproof doors and crouched behind the ATM at the entrance.

“Gunfire? Yeah, I’m down,” she said.

As soon as she heard the gunshots, “I was gone,” she said, noting she hid until she thought it was safe and looked up and saw so many bystanders and police that she couldn’t even see the intersection.

The incident is being jointly investigated by the Contra Costa County District Attorney’s office, the Contra Costa Crime lab, Pittsburg and Antioch police.

Police encourage anyone with information on the suspect or the shooting to call 925-778-2441 or text a tip to 274637 (CRIMES) using the keyword “Antioch”.
