COLUMBUS, Ohio – A police officer credits his training for allowing him to quickly stop the man responsible for a car-and-knife attack at Ohio State University a year ago, according to a video released Monday. That training "kept my whole world from collapsing in on me" during the moments during which he shot and killed the attacker, Ohio State Officer Alan Horujko said in the 14-minute video produced and released by the university. Horujko has declined interview requests. The university said he agreed to share his experiences through the video as the attack's one-year anniversary approached on Tuesday. The school plans a commemorative event Tuesday on campus.

COLUMBUS, OHIO – A Somali-born student who carried out a car-and-knife attack at Ohio State University might have been inspired by the Islamic State group and a former al-Qaida leader, investigators said Wednesday. Law enforcement officials said that it's too soon to say the rampage that hurt 11 people on Monday was terrorism. They said they aren't aware of any direct contact between the Islamic State group and the attacker, Ohio State student Abdul Razak Ali Artan. "We only believe he may have been inspired" by the group, said Angela Byers, the top FBI agent overseeing federal investigations in the southern half of Ohio. Artan also might have been influenced by Anwar al-Awlaki, a U.S.-born cleric who took a leadership role in al-Qaida before being killed in a 2011 U.S. drone strike in Yemen, Byers said.
