AP Source: Woman in shooting pledged allegiance to ISIS

SAN BERNARDINO, Calif. (AP) — The woman who helped her husband kill 14 people at a holiday banquet for his county co-workers pledged allegiance to the Islamic State group and its leader on Facebook using an alias, then deleted the messages before the attack, a U.S. law enforcement official said Friday, providing the strongest evidence to date that the rampage may have been a terrorist attack.
The remarkable disclosure about the online activities of Tashfeen Malik provided the first significant details suggesting a motive for her participation with her husband, Syed Farook, in the shooting.
