Two Suspects Killed After San Bernardino Mass Shooting

At least 14 people were dead and another 17 injured in a shooting Wednesday in San Bernardino, California, when a trio of gunmen who were heavily armed and "on a mission" opened fire during a function at a center for people with developmental disabilities, police said.

Up to three shooters, armed with assault weapons and "prepared to do what they did as if they were on a mission," opened fire around 11 a.m. at the Inland Regional Center, San Bernardino Police Chief Jarrod Burguan said.

The suspects fled the scene and hours later, police found what they believed to be the getaway car in the nearby city of Redlands, California. When the car left a house there, they followed it and a chase ensued.

There was an exchange of gunfire and two of the suspects -- a man and a woman -- were killed.

Video of the scene of where police and the suspects exchanged gunfire showed what appeared to be one suspect's body lying in a San Bernardino street. The second was removed from the bullet-riddled vehicle.

The suspects were dressed in "assault-style" clothing and armed with assault rifles and handguns, Burguan said. One officer suffered non-life-threatening injuries in the shootout. San Bernardino police spokeswoman Sgt. Vicki Cervantes said earlier that the suspects may have been wearing body armor.

Police were still investigating the vehicle Wednesday night, and what was believed to be a pipe bomb recovered was found not to be an explosive, McMahon said.

Police detained a third suspect in a Redlands neighborhood after receiving reports that someone was jumping a fence, San Bernardino County Sherriff John McMahon said. But it was not clear if he had weapons or was involved in the shooting.

The initial shooting at the social services center lasted for just "a few minutes" before the suspects fled.

Investigators were still trying to determine a motive, but have not ruled out terrorism.
