It is confusing. The article didn't mention TEP. Last night on the news it was reported a student was hit by a stray bullet after exiting their fraternity house. Then they showed the TEP house and interviewed a student on the front steps of the house. TEP is at 38th and Walnut where the student was shot. Maybe it was a guest that was shot or maybe it is a coed fraternity. I don't know for sure.
