Adam Garcia, university police chief, said two campus officers engaged the suspect in a shootout before being was struck and killed.

Kevin McMahill, Las Vegas Metropolitan Police Department sheriff, said earlier at a press conference that they had “no idea on the motive” as of now.

One additional victim is in stable condition at a local hospital, the sheriff said at a Wednesday evening press conference. Four other people were also taken to hospital for panic attacks and two police officers were treated for minor injuries.

One student who was on campus told a local ABC station that it seemed like police were on campus right away.

Describing the scene to the reporter he said: “You don’t know what to do. You’re calling your family, texting your friends like ‘I love you guys’ because he [the shooter] could burst through the door at any minute.”
