Police were searching on Monday for a third person in connection with a shooting that wounded a Fullerton police officer during a traffic stop over the weekend.
Two suspects, a man and a woman, were already in custody in connection with the case.
Investigators, meanwhile, were trying to determine if there was a man in the back seat of the car during the shooting, police said.
The shooting occurred at Woods and Knepp avenues at 12:15 a.m. Sunday, police said.
The officer, identified as J. Boline, a seven-year veteran of the department, was in good condition on Monday at a hospital.
He was shot several times in the upper body.
His external armored vest was credited with saving his life, said Fullerton police Sgt. Jeff Stuart.
The first round went into the officer's bullet-resistant vest, but the others, just outside of it, he said.
Stuart described the pain from the bullets as like someone hitting the chest with a bat.
Marcos Allen Bush, 29, of Santa Ana, was behind the wheel of the Pontiac Grand Prix and allegedly opened fire on the officer, Stuart said.
Police tracked Bush to a home in Anaheim where he was arrested Sunday after a short foot chase, police said.
While trying to run away from officers, Bush allegedly threw a pistol to the ground.
The gun was recovered and investigators were trying to figure out whether it was used in the shooting.
Bush was booked into the Fullerton jail on suspicion of attempted murder on a police officer, Stuart said.
"We're very confident that he's the shooter," Stuart said.
He has a “lengthy arrest record,” including arrests on suspicion of robbery, aggravated assault, carjacking and participation in a criminal street gang, police said.
He was released from custody less than two weeks ago after a jury acquitted him of attempted murder, his attorney, Doug Myers, told City News Service.
Bush was acquitted March 6 of carjacking and second-degree robbery in a case that involved a fistfight with a man accused in testimony of carrying on a relationship with an underage girl, who was the niece of Bush's girlfriend, according to Myers.
Also arrested in the Fullerton police shooting case was a woman identified as Sjanee Duhart, 27, of Riverside. He was arrested in Riverside while driving the Grand Prix, police said.
The car allegedly belongs to a relative.
She was booked into the Orange County Sheriff's Intake and Release Center on suspicion of being an accessory to the attempted murder of a police officer.
The Orange County District Attorney has until Tuesday to file charges in the case, Stuart said.
The Fullerton Police Department urged anyone with information on the shooting to call police at (714) 738-6838.
