OSHKOSH - University of Wisconsin-Oshkosh chancellor Richard Wells has outlined steps the university is taking in response to last weekend's shooting on campus.UW-Oshkosh police say they were called to Reeve Memorial Union around 11 p.m. Saturday for a report of a fight during a Black Student Union-sponsored dance. While police were there, they say someone fired a handgun into the ceiling. No one was hurt. The shooter has not been identified, but police do not believe he is a student.Meanwhile, some students have questioned why it took the university hours to send out a text-message alert about the incident."We must ... own what we did not do so well," Wells wrote in a statement issued Thursday.According to Wells, the university is taking steps including designating and training more staff members and university police officers on sending out text-message alerts; creating stronger event management planning to incorporate reliable attendance projections and capacity limits; and improving planning by hosts, staff members and police, and making more security measures available, including tools such as metal detection wands.Wells also says a temporary moratorium on most nighttime events has been put in place while security improvements are being discussed.Wells believes there is no ongoing threat to campus safety.
