San Francisco Shooting: 4 killed including the gunman

A gunman shot and killed three people at a United Parcel Service facility in San Francisco on Wednesday morning before fatally shooting himself in front of police officers, authorities said.

Two others were wounded by gunfire, according to San Francisco police, and five had injuries that were probably sustained during the rush to evacuate.

The lone gunman, identified by police as Jimmy Lam, 38, shot himself in the head, Assistant Chief Toney Chaplin said. Two guns were recovered at the scene.

Authorities said the incident was not believed to be connected to terrorism. Police Chief William Scott said that investigators were uncertain about Lam’s motive.
