Any potential motives of the shooter are unclear and not confirmed. One student said the gunman was asking students about their religion before shooting, according to UCC's college newspaper The News Review.

"The shooter was asking people to stand up and state their religion and then started firing away," the paper reported, citing 18-year-old Kortney Moore. Moore was reportedly in a writing class when she saw a gunshot come through the window. She also said that she saw her teacher shot in the head, the News Review stated.
