Two women killed, man wounded in attack at San Francisco jewelry market

Two women were killed and a man was wounded in an attack at a store in a busy San Francisco jewelry market Friday, authorities said. Police arrested a blood-covered man who they said twice opened fire on officers.

Officers initially responded to reports that multiple people had been shot at the GiftCenter & JewelryMart in the city's South of Market district about 2 p.m. (5 p.m. ET) and encountered a man running out of the store.

San Francisco Police Chief Greg Suhr said the man, who was covered in blood, opened fire on the officers. He then fled to a nearby restaurant, where he opened fire on a second group of officers before he apparently ran out of ammunition, at which point he surrendered.

The man had a revolver and an "edge weapon" — described as a folding knife — when he was taken into custody. He was being treated for superficial wounds, Suhr said. 

It wasn't clear whether the blood that covered him was from his wounds or from the victims, Suhr said..

Inside the market, police found the bodies of two women and a man who had been wounded in the lobby of one of its many jewelry stores. The cause of their wounds hadn't been determined, Suhr said, and no further information about them was immediately available.

Suhr said the male victim was stable at a hospital.

Suhr said police believed there was only the one suspect, but he said officers were scouring the area "out of an abundance of caution." He asked people in the area to stay indoors and shelter in place for the time being.

The block where the shootings occurred is lined with jewelry stores and is near the Concourse Exhibition Center, a venue for large conventions and trade shows. No events were taking place there Friday, according to the site's event calendar.
