SAN FRANCISCO -- An Antioch man has been identified as the gunman in a jewelry store shooting that left two dead and one critically injured Friday, police said.

Barry White, 23, was booked into San Francisco County Jail on suspicion of two counts of murder and seven counts of attempted murder after being treated for superficial hand wounds at San Francisco General Hospital, according to a San Francisco Police Department spokesman.

White attacked three employees of Victoga Inc., a jewelry store in the GiftCenter & JewelryMart complex at 888 Brannan St., with a handgun and a knife, police said. Two of the employees, both women, died at the scene; the third employee, a man, is in critical condition at a hospital.

After the attacks, White left the GiftCenter and walked east on Brannan Street, where six San Francisco police officers attempted to stop him as they responded to the scene.

White raised his handgun and fired at the approaching officers, then retreated to a nearby restaurant and again fired at them, police said. No officers were struck by the gunfire, and the officers did not return fire before White surrendered.

According to police, it appears White had at least one prior business transaction at the jewelry store before Friday's attack.

Robbery does not appear to be the motive, and police said it appears White acted alone in the attack. A cause has yet to be revealed.

A call to White's Antioch home was answered by an unknown individual who said the family does not wish to comment, adding: "He was not the shooter," before hanging up.
