This shooter is dead. The one that she describes killed himself. He was the second shooter.

The first shooter has not been identified. They have a "person of interest" in custody for the first shooting, but they don't know if both shootings are connected. They haven't gotten the ballistics back yet to make that conclusion.

Personally, I think it isn't likely that these shootings aren't connected. Two shootings in one day, on one particular campus? Doesn't seem like a coincidence to me.
