"This car just swerved and ran into a whole group of people," said Nicole Kreinbrink, who was walking down the street when she saw the car hit people who had evacuated an academic building during a fire alarm.
"All these people were running and screaming and yelling," she added.
Jacob Bowers, an OSU sop re, was sitting on a bench about 100 feet away when he noticed people running.
"Then I heard someone yell, 'He's got a knife.' And I saw a guy with a big-ass knife just chasing people around. When I saw that, I grabbed all my stuff and started running," Bowers said.
Bowers said he looked back to see a police officer on the scene. The officer yelled to the suspect, "Drop it and get down or I'll shoot," and then fired on the suspect, Bowers said.
"The man was going insane," he said.
