At least 14 dead, 14 wounded in San Bernardino shooting

NBC Los Angeles reports that San Bernardino, California police officers are in a standoff with possible suspects from the shooting that killed at least 14 people at the Inland Regional Center earlier Wednesday.

The standoff is taking place on San Bernardino Avenue north of Interstate 10, NBC Los Angeles reports. The shooting at the Inland Regional Center started at about 11 a.m., and left at least 14 people dead and 17 wounded, according to police officials who spoke at an afternoon press conference. Police said there are as many as three suspected shooters who may have fled the scene in a dark vehicle; details as to who the shooters are, if the shooting was an act of terrorism, and the motive behind the shooting remain unclear.

"These were people who came prepared," San Bernardino Chief Jarrod Burguan said, adding that the attackers were believed to have used "long guns," not hand guns. No weapons were recovered at the scene.

Marybeth Feild, Inland Regional Center Board of Trustees president, said the shooting took place in a large conference room rented by a healthcare provider. She was not inside the building at the time, but received phone calls from employees saying three shooters went into the room. "I don't even understand why they would target these individuals," she told the Los Angeles Times. "This is very bizarre. I don't know why anybody would want to hurt people who provide disability services."

Schools across San Bernardino are on lockdown, with no one allowed on or off campus, NBC Los Angeles reports. Victims have been taken to nearby Loma Linda University Medical Center and Arrowhead Regional Medical Center, where police officers and SWAT members are guarding the ER and other hospital entrances, the San Bernardino Sun reports.
