LOS ANGELES (CBSLA.com) — The first image of accused San Bernardino killer Tashfeen Malik has been released by the media.

Investigators have said she posted a pledge of allegiance to ISIS on her facebook page around the same time as when the attacks began.

The FBI says that evidence suggests that both Malik and her husband Sayd Farook were both radicalized by Islamic fundamentalists.
