Investigators: Ohio State attacker was inspired by ISIS and Al-Awlaki

Authorities say Abdul Razak Ali Artan, who was killed by an Ohio State University campus policeman Monday after a short stabbing spree, was inspired by both ISIS. The sources point to Facebook posts made by Artan about deceased Yemeni-American cleric Anwar al-Awlaki and the style of the attack encouraged by ISIS in a recent online magazine. Investigators couldn't say whether Artan had communicated with either ISIS or al-Qaeda.
