At least 58 people have been killed and at least 515 injured in the deadliest mass shooting in modern US history. A gunman fired on the Route 91 Harvest country music festival in Las Vegas from an overlooking hotel.

Police have named the suspect as Stephen Paddock, a 64-year-old local man. They believe he shot and killed himself on the 32nd floor of the Mandalay Bay hotel and casino. At least 10 guns were found in his hotel room. Police found a number of rifles in Paddock’s hotel room.

Guns and ammunition were also found in Paddock’s home in Mesquite, Nevada after authorities executed a search warrant early Monday morning. A police spokesman said there was “nothing unusual” at Paddock’s “nice, clean home” in a newer part of Mesquite.

Videos taken by concertgoers at the festival show people screaming and running as multiple gunshots can be heard.

A witness says it sounded like a “machine gun.”

According to scanner reports, multiple people have been shot, including a police officer.

The conditions of the victims were not immediately available.
