Investigators were looking into a message posted on Facebook by Artan, Ohio State University attacker, that contained inflammatory statements about being "sick and tired" of seeing Muslims killed and reaching a "boiling point," a law enforcement source told Reuters news agency. "Stop the killing of the Muslims in Burma," Artan said in the Facebook post. Violence in Myanmar, which is also known as Burma, has sent Rohingya Muslims fleeing across the border to Bangladesh amid allegations of abuses by security forces. All of Artan's Facebook postings have been removed from the social media website. Artan on Facebook also called Anwar al-Awlaki, a U.S.-born radical cleric linked to al Qaeda's Yemen wing, "a hero." Awlaki was killed by a U.S. drone strike in 2011. In its claim of responsibility for Monday's attack at Ohio State, the Islamic State news agency AMAQ posted a photo of Artan wearing a blue shirt and sitting with greenery in the background. It described him as a soldier of the group. "Brother Abdul Razak Ali Artan, God accept him, implementer of the Ohio attack, a student in his third year in university," the caption read.
