SAN BERNARDINO, Calif. — Two suspects — a man and a woman — are dead after hundreds of police officers swarmed a six-block area of San Bernardino in pursuit of the killers who gunned down 14 people and injured 17 others at a holiday party.
Syed Farook, 28, and Tashfeen Malik, 27, were identified late Wednesday night as the suspects in the deadly shooting, according to San Bernadino Police Chief Jarrod Burguan.
It is believed they were a couple.
Burguan said the motive still isn't known but is "confident" the deceased suspects were the only two shooters, not three as previously thought.
He also said "terrorism" has not been ruled out as a possible motive. Burguan also believes "there had to be some degree of planning" and it wasn't a spur of the moment operation.
"I'm still not willing to say that we know that for sure," said an FBI official on whether it's terrorism, saying there are some adjustments they are making to their investigation.
Several officers shot at the SUV which contained the two suspects, who were wearing tactical gear and had rifles.
Earlier police said they were hunting as many as three suspects, who had fled in a black SUV.
San Bernardino police reported that one person left a holiday party after a "dispute" and before the massacre happened — it wasn't clear if that person returned to the party at the center for people with developmental disabilities.
Witnesses told police the gunmen fled the scene of the shooting at the Inland Regional Center in a black SUV. Hours later, helicopter images showed two armored trucks approaching a black SUV riddled with bullet holes. A person could be seen on the ground in blood not moving, with a long gun by his side.
Law enforcement officials told CNN that two suspects were in the SUV armed with AR-15-type weapons and threw what are believed to be pipe bombs out the windows as police closed in. It
A police officer was also hurt, but the injury is not life-threatening, police Sgt. Vicki Cervantes said.
City spokesman Carl Baker says Redlands police are assisting San Bernardino police in the search connected to the shooting.
Residents in the area are urged to stay inside as SWAT teams search for at least one suspect in a blocked off area outside an apartment building in Redlands, California.
Earlier, police exchanged fire in San Bernardino in a pursuit that ended with a "suspect down," a San Bernardino police official said. A black SUV, which was riddled with bullet holes, was surrounded by authorities. Helicopter video shows a person splayed on the ground, bleeding.
The "active scene" is a few miles away from the site of the massacre.
Officials pursued the three culprits who "came prepared" and had long guns they used in the attack at the Inland Regional Center, according to the San Bernardino police chief Jarrod Burguan.
He said the motive was unclear. “We do not know if this is a terrorist incident,” said David Bowdich, who directs the FBI’s Los Angeles Field Office.
"They came prepared to do what they did as if they were on a mission," Burguan said.
“Up to three people had entered the building and opened fire on people inside the building,” Burguan said at an earlier press conference. “Information that I think is probably the most reliable at this point is that the suspects have fled, potentially in a dark-colored SUV.”
The president and CEO of the service center said the mass shooting happened in a conference area where the San Bernardino County Department of Public Health was hosting a banquet, the AP reported.
The call first came in about 11 a.m. local time of the incident of 1365 S. Waterman Ave.
The day before the shooting, the facility held a holiday party, video posted to the organization's Twitter page shows.
Dave Hall, whose daughter goes to the social services facility, told KTLA the center is used by those with mild to severe autism.
"Who would think of such a thing to make an attack at that kind of facility?" Hall said.
Terry Petit's daughter works at Inland Regional Center and sent her father a text saying she was hiding after gunfire erupted at her office.
Choking back tears, Petit read the message from his daughter.
"People shot. In the office waiting for cops. Pray for us. I am locked in an office," she wrote.
The Inland Regional Center is a facility run by the state of California that works with people living with developmental disabilities. Workers at the facility threw a holiday party for the people being treated at the center and posted video to Twitter with the message, "The ICF Holiday Party is in full swing!"
Aerial footage of the scene showed a massive triage operation, set up in the middle of an intersection near the scene, and multiple people being put on stretchers and loaded onto ambulances.
Survivors emerged from the facility in droves. Police searched people filing out of a building with their hands up before they reunited with loved ones.
A city of nearly 210,000, San Bernardino sits about 60 miles east of Los Angeles.
The sheriff's department there called on the public for information in the shooting. Any details can be reported anonymous to We-Tip at 1-800-78-CRIME.
President Barack Obama has been briefed on the shooting and has asked to be updated as the situation develops, according to his Homeland Security advisor Lisa Monaco.
"The one thing we do know is that we have a pattern now of mass shootings in this country that has no parallel anywhere else in the world," the president told CBS News after the San Bernardino shooting.
The incident comes five days after another high-profile shooting in which a gunman opened fire at a Planned Parenthood facility in Colorado Springs, Colo., killing two civilians and a police officer.
