Breaking: Female Suspect in San Bernardino Shooting Reportedly Pledged Allegiance to ISIS

The female suspect accused by the police of carrying out Wednesday's deadly rampage in San Bernardino, California, swore her allegiance to the leader of ISIS in a Facebook post that has since been deleted, according to several news outlets, including the New York Times and NBC. The post was reportedly written the same day of the shooting.

Speaking on the condition of anonymity, federal government officials say Tashfeen Malik, the 27-year-old wife of suspected gunman Syed Rizwan Farook, 28, used an alias Facebook account to write a post in support of the terrorist group.

It's unclear at this time if ISIS militants actually ordered the couple to carry out the shooting. Multiple motives are still being investigated by the police and the FBI, including a possible workplace-related grievance.

On Wednesday, Malik and Farook opened fire inside the Inland Regional Center, a social services agency, killing 14 people and injuring 21, prompting a massive manhunt and an eventual shoot-out with the police that killed the assailants.
