UPDATE:5:30 p.m. The New York Times reports that one of the three attackers "had worked at the facility and recently had a dispute with fellow employees, according to law enforcement officials.

"They had their appearances covered but a witness believed it had been someone who worked there," said one official."

UPDATE:4:30 p.m. According to the most recent reports, one suspect is still on the run. One officer has been injured. The victims of the mass shooting were reportedly attending a Health Department luncheon; the attackers' motives remain unclear.

UPDATE:3:38 p.m. Live footage shows SWAT teams converging on a stationary, shot-up black SUV in San Bernadino. According to police, it is the escape vehicle from the earlier mass shooting.

In San Bernardino, CA, at least 14 people have been killed and 14 more injured after a mass shooting this morning. The San Bernadino police chief says authorities have "no idea" who or where the suspects are, and describes it as "domestic terrorism." The suspect or suspects are said to have been well armed, with "long guns" and "body armor." They came prepared, said the chief.

The first emergency call came in to 911 around 11:00 a.m. Pacific time. The San Bernardino Fire Department said victims were in the 1300 block of Waterman Avenue. Police say there are one to three suspects, all of whom were heavily armed and may be wearing body armor. The shooting happened at Inland Regional Center, one of 21 State of California facilities that serve people with developmental disabilities, a spokeswoman for the CA Dept of Developmental Services told Reuters.

The social services agency is among regional centers throughout California that administer, authorize and pay for assistance to people with disabilities such as autism and mental retardation.

On an average day, doctors at the regional centers would be evaluating toddlers whose parents have concerns and case workers meeting with developmentally disabled adults. Lungren said that the San Bernardino facility is one of the state's largest and busiest.

The president and CEO of Inland Regional Center says the shooting took place at a building that houses some 25 employees, and a library and conference center. From AP:

Marybeth Feild of the Inland Regional Center says "the incident is in the conference area" that an outside group was renting Wednesday. She says she is not at the center, which serves people with developmental disabilities and does not know what outside group rented the center.

Authorities have been seeking an SUV that fled from the shooting location. There was a report on the police scanner of a suspect in a black Chevy Yukon wearing a black mask.

Police used a robot to detonate a suspicious device found on-site, according to the sources who spoke to the Los Angeles Times.

The San Bernardino County Sheriff's Department confirmed an active shooter in the area of Orange Snow Road and Waterman Avenue.

The Los Angeles Times further reported that images on Twitter and Facebook show heavily armed police surrounding a neighborhood in San Bernardino.
