Creighton officials announced Wheeler’s banning and the frat’s suspension at a press conference Monday afternoon.

“I would like to emphasize that this was an isolated attack and there is no ongoing threat to the campus community,” Berscheidt said.

Creighton spokesman Jim Berscheidt said another student reported that Wheeler knocked him down in a dorm elevator before the knife incident. That student suffered minor injuries and was treated at Creighton University Medical Center and released.

Harner said she was in the elevator during that altercation. It occurred roughly 15 minutes after she had left Wheeler lying on the dorm floor. She and a group of friends had gone back to take Wheeler to another friend’s room. In the elevator, he shoved a member of the group. After the doors opened, Wheeler ran off.

“He was clearly scared and was not in his right mind,” she said. An attempt by The World-Herald to reach that student was unsuccessful.

About 1 a.m. — Harner didn’t know if it was before or after the slashing — Wheeler met up with the group and they talked with him. But, still paranoid, he again ran off.

Wheeler could be allowed to return to campus, based on the outcome of the investigation.
