President Trump responds to Las Vegas shooting in national address [LIVE VIDEO]

According to Fox News, 64 year old Stephen Paddock, a white male, turned the sold-out Route 91 Harvest festival into a killing field Sunday night. Using at least 10 guns, Paddock fired into the crowd of concert goers from his balcony on the 32nd floor of the Mandalay Bay Resort and Casino, murdering at least 50 people and injuring more than 400 others in one of the deadliest mass shootings in modern United States history.

The suspect was a resident of Mesquite, Nevada. He died of a self-inflicted gunshot wound. At first, police were searching for Marilou Danley, as a person of interest and who was also believed to be Paddock's roommate. Detectives later made contact with her, and "do not believe she is involved with the shooting on The Strip."

Authorities first received calls about an active shooting at about 10:08 p.m. Country music star Jason Aldean was performing his last song of the night. Initially, those in attendance said they thought the sound was firecrackers. But as the shots continued, Aldean stopped singing and some concertgoers could be heard yelling to each other to get down.

The gunfire was rapid and some in attendance reportedly confused the sounds with firecrackers.

Clark County Sheriff Joseph Lombardo said an "excess of 10 rifles" were found in the room, but did not immediately reveal a motive. Paddock had been in the hotel room since September 28, according to Lombardo.
