Tashfeen Malik, the female shooter who opened fire at the Inland Regional Center in San Bernardino, pledged allegiance to the Islamic State (ISIS) group in an online posting, according to news reports on Friday. The posts increase the likelihood that the shooters were inspired by the Islamic State, though investigators have so far found no evidence to indicate that the attack was directed by ISIS. Investigators are now looking to determine whether it was Malik who was the radicalizing influence in the life of the second shooter; her husband Syed Farook, NBC News reported.
