Man kills 3 at Vegas college

Terrified students and professors cowered in classrooms and dorms as a gunman roamed the floors of a University of Nevada, Las Vegas building, killing three people and critically wounding a fourth before being shot dead by police. The gunman was a professor who had unsuccessfully sought a job at the school, a law enforcement official said. Police didn’t immediately identify the victims, the attacker or the motive and didn’t say what kind of weapon was used, although some witnesses reported hearing as many as 20 shots fired. The attack was the worst shooting in the city since Oct. 2017, when a gunman killed 60 people after opening fire from the window of a room at Mandalay Bay casino on the Las Vegas Strip.
