COLUMBUS, Ohio -- The latest on reports of an active shooter on the Ohio State University campus:
Authorities say the officer who killed an attacker at Ohio State University was a university police officer who'd been on the job for less than two years.
Department of Public Safety Director Monica Moll identified the officer as 28-year-old Alan Horujko. She says he started on the Ohio State police force in January 2015.
Ohio State Police Chief Craig Stone says it was fortunate there was a nearby gas leak that the officer had gone to investigate. Stone says it helped position Horujko to respond to the attack so quickly.
Those injured in the attack included an Ohio State faculty member, four graduate students and three undergrads.
Authorities say they were able to get photos of the suspect's vehicle driving onto campus and confirmed only one person was in the car.
A director of public safety says a man who drove a car into pedestrians and began stabbing people at Ohio State was a student at the school.
Ohio State Department of Public Safety Director Monica Moll also identified the now-deceased suspect as Abdul Razak Ali Artan.
A U.S. official earlier told The Associated Press that he was born in Somalia and living in the United States as a legal permanent resident. The official wasn't authorized to publicly discuss details of the ongoing case and spoke to The Associated Press on condition of anonymity.
Authorities say Artan was shot to death by a police officer Monday morning shortly after he drove up onto a curb into pedestrians, got out of the car and began stabbing people with a butcher knife.
