At least 14 people are dead after a shooting in San Bernardino, California — about 60 miles east of Los Angeles.

The shooting happened at the Inland Regional Center, a county agency that provides services to the disabled.

San Bernardino Police Chief Jarrod Burguan told reporters that at least 14 people are dead and 17 more were injured in the shooting, which police responded to at about 11 a.m. local time, according to emergency officials.

"They came prepared to do what they did as if they were on a mission. They came in with a purpose," Burguan added, noting that the shooters were armed with long guns rather than hand guns. "They came in with the intent to do something."

One of the three suspects has been identified as Syed R. Farook, the LA Times reported, citing two law enforcement sources. The Associated Press has also cited law enforcement sources identifying Farook as a suspect.

According to the LA Times report, an exchange was "overheard on a law enforcement radio channel" in which an official could be heard telling a dispatcher Farook "was at the meeting" at the Inland Regional Center and "was acting nervous" then "left out of the blue," minutes before gunfire began.

Hours after the massacre, Burguan said that police received a tip related to the shooting that led officers to a home in the city of Redlands, just south of San Bernardino. As police were setting up to watch that home, a dark-colored SUV was seen leaving the residence,Burguan said.

The suspects' vehicle had been described as a dark-colored SUV.

A police chase began and ended in a shootout involving San Bernardino Police. A dark-colored Ford Expedition could be seen in the street, windows shattered, less than 2 miles from the scene of the mass shooting.

Two suspects — one male and one female — were killed in that shootout with police, according to investigators.

A third person who ran away from that scene has been detained, according to David Bowdich with the FBI's Los Angeles bureau. It wasn't clear whether that person was involved.

Both of the dead suspects were armed with "assault-style weapons" and handguns, law enforcement officials report.

One police officer who was shot suffered non-life-threatening injuries.

The Press Enterprise reported thata bomb threat was called in to Loma Linda University Medical Center, where medical personnel were treating the wounded on Wednesday afternoon. Investigators later determined that that threat was not credible.

A representative for the US Bureau of Alcohol, Tobacco, Firearms and Explosives said that the agency was investigating at least one possible pipe bomb at the Inland Regional Center. Police officials said at a news conference that hundreds of people were in the building at the time of the shooting there.

Most of the victims, Burguan said, "were centrally located in one area of the facility."

"They [Inland Regional Center] had an event today, and during that event is when multiple shooters came in and just started shooting," Sgt. Vicki Cervantes, a San Bernardino Police Department spokeswoman, told ABC 7.

The event was a county-personnel banquet, Inland Regional's executive director, Lavinia Johnson, told CNN.

The center has 670 employees, according to its Facebook page. San Bernardino is roughly 60 miles east of L
