LAS VEGAS — 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 shock waves through a city still scarred by the deaths of 60 people in a 2017 mass shooting only a few miles away on the 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 and dorm rooms.
