 A gunman killed three people and critically wounded a fourth Wednesday at the University of Nevada, Las Vegas, before being killed in a shootout with police, authorities said. The attack sent shockwaves through a city still scarred by the deaths of 60 people in a 2017 mass shooting only a few miles away on the famous Strip. Reports of shots fired at about 11.45 a.m. sent police swarming onto the campus while students and professors barricaded themselves inside classrooms in dorm rooms, .unlv. Chief Adam Garcia said at an evening news conference that campus and local police rushed to the scene, a building housing UNLV's lead business school, where two university detectives killed the suspect during a shootout.
