'Active shooter on campus!' You can hear the Mommies and CSGV typing as you read it,

but:
An Ohio State spokesman says some students were stabbed, others injured after being hit by a vehicle. Other injuries are also being evaluated.

So I check another news site:
Hospital officials told the Associated Press eight patients they received from the scene have non-life-threatening injuries. The eight patients were split among OSU Wexner Medical Center, OhioHealth Grant Medical Center and OhioHealth Riverside Methodist Hospital.
The injuries include stab wounds, injury by motor vehicle and other injuries that are being evaluated.
So far it sounds like the only 'active shooting' was the cops punching his ticket.
