*(Via Huffington Post) – Police in San Bernardino, California, are still piecing together the details of a shooting that killed 14 people and wounded 17 others at a social services center.

The shooting was deadliest in America since the 2012 attack on Sandy Hook Elementary School in Newtown, Connecticut. Wednesday’s shooting took place during a holiday party at the Inland Regional Center. The suspected attackers, Syed Rizwan Farook and his partner Tashfeen Malik, were later fatally shot during a police chase.

Police have not released any clues as to why Farook and Malik opened fire on the party, which Farook had attended earlier in the day and reportedly left angry. But David Bowdich, a regional director with the FBI, said that they couldn’t rule out terrorism.

The couple “came prepared to do what they did as if they were on a mission,” San Bernardino Police Chief Jarrod Burguan said. Police said that the pair carried two assault rifles, two handguns, and wore masks and tactical gear. A spokeswoman for the Bureau of Alcohol, Tobacco, Firearms and Explosives told the Los Angeles Times that at least two of the guns were purchased legally.

An official with the Council on American-Islamic Relations cautioned against speculation.

“Is it work? Is it rage-related? Is it mental illness? Is it extreme ideology,” CAIR-Los Angeles executive director Hussam Ayloush said. “We just don’t know.”
