Update (2:26 CST): The attacker was first identified from the police dispatch as Ali Muhammad. But it now appears that his name is Abdul Razak Ali Artan. If we believe the police dispatch, then it's unclear whether he registered his car under a different name or whether he was driving someone else's car.
Multiple sources including CBS Evening News are now reporting that the OSU attacker was Somali Muslim. According to the police dispatch, below, he was identified from the license plate of his car (the ID is at 5:25 to 6:15).
Muhammed drove his car into a group of students on the Ohio State University campus. He then jumped out of the car and started attacking with a butcher knife.
An officer in the area responded within a minute and shot Muhammed dead.
There are nine injuries - most minor, one critical, none life threatening.
