2 Suspects Dead in San Bernardino

Big developments in the San Bernardino mass shooting: Police chased a black SUV—the type of vehicle seen fleeing the shooting—resulting in a shootout that left two suspects dead, a man and a woman, reports the Los Angeles Times. Both are still unidentified, and Police Chief Jarrod Burguan said they were armed with assault weapons and handguns. One officer was wounded in the shootout. A third person seen running from the original shooting scene has been detained, but he hasn't officially been declared a suspect. Burguan said police, acting on a tip after the mass shooting, went to a residence and soon saw the SUV leaving the home, prompting the police chase.

Earlier reports said three suspects wearing body armor and armed with long guns opened fire in an auditorium of a social services facility, killing 14 and wounding 17. The auditorium was reportedly being used at the time by employees of the county health department for a holiday party. There's still no official word on a motive. "Is this a terrorist incident? We do not know," said David Bowdich of the FBI. But reports are emerging that the shooting was sparked by an argument at the party. (More mass shootings stories.)
