On December 2, 2015 at 11:00 a.m. PT (1:00 p.m. CT), 14 people were killed and 17 wounded during a holiday party at Inland Regional Center, a facility for developmentally disabled people, in San Bernardino, California. At the center of the shooting was a married couple, Syed Rizwan Farook and Tashfeen Malik. Dressed in black and each carrying a semi-automatic rifle and a handgun, the authorities said that the two “unleashed a massacre Wednesday at the party hosted by the San Bernardino County, California health department.”

Afterwards, they led the police on a chase ending with their deaths. According to the city’s police chief, there was a dispute at the holiday party between Farook and a co-worker. Regardless what the argument was over, it appeared that this shooting was planned out based on what they did and the firearms they had. “We do not know yet why this terrible event occurred,” said President Barack Obama.

Obama noted that terrorism and “mixed motives” were possibilities, but the extent of their plans and their motivations were unknown. At 12:13 p.m. ET today, December 3, law enforcement officials said that Farook “was apparently radicalized and in touch over the phone and via social media with more than one international terrorism subject who the FBI were already investigating.”
