Abdul Razak Ali Artan, the 18-year-old Ohio State student whose 2016 campus attack injured 11 other students and workers, was likely influenced by the extremist ideology of the Islamic State group but never directly contacted or received instruction from any terrorist organization, the Federal Bureau of Investigation announced Tuesday afternoon.
"We thank all of our partners involved, including the Ohio State University Police Division, Columbus Division of Police, Columbus Division of Fire, Ohio State Highway Patrol, and the Franklin County Sheriff's Office, for their efforts in the response and investigation of this horrific attack," the Cincinnati division of the FBI said in a news release.
According to the release, the investigation into the incident had been completed and investigators did not anticipate releasing any more information.
Artan, who arrived in the United States as a Somali refugee, launched his attack Nov. 28, 2016, armed with a Honda Civic and butcher knife. Less than two minutes after driving the car into a crowd of pedestrians and exiting to attack others with a knife, Artan was killed by Ohio State University Police Officer Alan Horujko.
