California shooting: What we know so far

A SWAT vehicle carries police officers near the scene of a shooting in San Bernardino, Calif. on Wednesday, Dec. 2, 2015.

One or more gunmen opened fire Wednesday at a Southern California social services center, shooting multiple people, authorities said.

“They came prepared to do what they did as if they were on a mission”, said San Bernardino police chief Jarrod Burguan.

Police were still hunting for the shooter or shooters, saying one to three possible suspects were being sought, and said it was not immediately clear what the motive was.

A police officer suffered injuries in the confrontation and was hospitalized with injuries not believed to be life threatening. Preliminary info is a suspect is down, officers are ok.

An FBI official on the scene said investigators do not know at this time if the attack has anything to do with worldwide terrorism. Courts, schools and other facilities in San Bernardino were placed on lockdown for security. He did not say if the dead and wounded worked at the center or were clients. “People shot.” Pettit told KABC his daughter told him 10 to 20 people were shot. A third person was detained while fleeing the scene of the shootout, which took place in a street a few miles from the Inland Center.

“We’re in a locked office”, she added in a second message.

Authorities have found several suspicious items in the building, one of which may be an explosive, police said. Police responded to reports of an active shooter at a social services facility. He said a shooter entered the building next to his wife’s office and opened fire.

The residential area not far from where the shooting at the Inland Regional Center occurred was flooded with law enforcement following a chase that ended with police and the suspects exchanging gunfire. “We must take action to stop gun violence now”, Hillary Clinton, the Democratic presidential, candidate said.

The Inland Regional Center coordinates support services for people with developmental disabilities in Riverside and San Bernardino counties “so they can live more independently in the community”, California Department of Developmental Services spokeswoman Nancy Lungren said.
