Ohio State University Police chief Craig Stone told reporters in a press conference early Monday afternoon that a male suspect struck pedestrians with a motor vehicle before exiting the vehicle and "cutting" bystanders with a butcher knife.
"Our officer was on scene in less than a minute and he ended the situation in less than a minute," Stone told reporters. "The investigation is ongoing."
Asked if the attack was planned, Stone said that it was "too early to say" but that the attack "was done on purpose."
The university’s Department of Public Safety director, Monica Moll, told reporters that a state police officer shot and killed the suspect. The Columbus Department of Public Safety confirmed this report to ABC News as well and said that it is searching for other possible suspects.
Stone said that nine people were transported to hospitals after the attack, eight of whom were in stable and one of whom was in critical condition.
Chief medical officer Andy Thomas of Ohio State University Wexner Medical Center said that his center received five wounded individuals, out of which two had stab wounds and two "with wounds related to being hit by the car." He told reporters that two other individuals were taken to Grant Medical Center and two "motor vehicle accident victims" were taken to Riverside Methodist Hospital.
Ohio Gov. John Kasich (R) responded to the situation:
Ohio's thoughts and prayers go out to the Ohio State community. Be safe, listen to first responders. https://t.co/5qtfH3Fb6d
