At Least 14 People Murdered in Mass Shooting in San Bernardino (VIDEO)

This story is developing.

At the San Bernardino Press-Enterprise, "SAN BERNARDINO SHOOTING: Massive police response following shootout with suspects in SUV (BREAKING)."

And at the San Diego Union-Tribune, "14 dead, more than a dozen wounded in California shooting":

SAN BERNARDINO, Calif. (AP) — As many as three gunmen believed to be wearing military-style gear opened fire Wednesday at a Southern California social services center "as if they were on a mission," killing at least 14 people and wounding more than a dozen others, authorities said.

Hours later, police hunting for the attackers riddled a black SUV with gunfire several miles away, and one person lay motionless in the street — dead or dying — with a gun nearby. Officers appeared to remove a second person from the vehicle.

San Bernardino Police Sgt. Vicki Cervantes said authorities had not immediately confirmed whether those in the SUV were involved in the morning carnage. And the hunt went on, apparently for a possible third gunman. A law officer suffered minor injuries in the afternoon shootout.

It was the nation's deadliest mass shooting since the Newton, Connecticut, attack in December 2012 that left 26 children and adults dead.

Police shed no light on a motive for Thursday's massacre, which came just five days after a gunman opened fire at Planned Parenthood in Colorado, killing three.

"They came prepared to do what they did, as if they were on a mission," San Bernardino Police Chief Jarrod Burguan said, noting the attackers carried long guns — which can mean rifles or shotguns.

Witnesses said several people locked themselves in their offices, desperately waiting to be rescued by police, after gunfire erupted at the Inland Regional Center, which serves people with developmental disabilities. Some people telephoned their loved ones and whispered to them what was going on.

The attack took place in a conference area where the San Bernardino County Department of Public Health was renting space to hold a banquet, said Marybeth Feild, president and CEO of the center. She said the building houses at least 25 employees as well as a library and conference center.

FBI agents and other law enforcement authorities converged on the center and searched room to room for the attacker or attackers, but it was feared that they had escaped.

Ten of the wounded were hospitalized in critical condition, and three were in serious condition, San Bernardino Fire Chief Tom Hannemann said. Police cautioned that the numbers of dead and wounded were early estimates that could change.

No weapons were recovered at the center, though authorities were investigating unidentified items in the building and brought in bomb squads, Burguan said.

San Bernardino police spokesman Sgt. Vicki Cervantes told The Associated Press there were reports from witnesses of one to three gunmen.

As the manhunt went on, stores, office buildings and at least one school were locked down in the city of 214,000 people about 60 miles east of Los Angeles, and roads were blocked off...
