LAS VEGAS (KLAS) — Two people are dead and the suspect is at large following a shooting in front of the landmark fountains at the Bellagio Resort & Casino on the Las Vegas Strip.

The shooting was reported around 10:40 p.m. Sunday when two Las Vegas Metropolitan police officers discovered two people with gunshot wounds on the sidewalk, according to Undersheriff Andrew Walsh. He said the officers had been on routine patrol when they heard gunfire and ran toward the area.

Both gunshot victims were pronounced dead at the scene.

Walsh said the suspect is known to police but not in custody, and the shooting is an “isolated incident” that stemmed from a conflict between the suspect and the victims.

“The suspect and victim had previously engaged in some type of conflict using a variety of social media platforms,” Walsh said.

Witnesses told Nexstar’s KLAS that they saw the shooter throw the gun in some bushes, and police recovered it.

Video of the purported shooting posted on social media showed a man with a gun pointing toward another man off camera. KLAS has not verified the authenticity of the video.

Police said there was a Zoox robotaxi in front of the fountains at the time of the shooting. Those vehicles have wrap-around exterior cameras.

Part of Las Vegas Boulevard was closed until around 5:30 a.m. Monday.

The identities of the shooting victims were not immediately released.
