Mass Shooting at Las Vegas Concert Kills 59, Injures 527

Authorities identified suspect as Stephen Paddock, who fired down on outdoor country music concert from 32nd floor of Mandalay Bay Resort

At least 59 people were killed and more than 500 injured when a shooter fired round after round from a high-rise room at Las Vegas’ Mandalay Bay Resort and Casino down onto a crowded country music concert.

The suspect, identified as a 64-year-old white man named Stephen Craig Paddock of Mesquite, Nevada, was found dead on the 32nd floor of the hotel with a cache of “in excess of 10 rifles,” Clark County Sheriff Joe Lombardo said.

“We believe the individual killed himself” just before authorities entered his room, Lombardo said.

At an earlier press conference, Lombardo said, “We believe it’s a sole actor, a lone-wolf-type actor.” He said investigators were executing a search warrant to enter his home roughly 80 miles outside of Las Vegas for more evidence, including a possible motive for the attack.

It was the deadliest mass shooting in modern U.S. history, surpassing the terror attack at the Pulse gay nightclub in Orlando, Florida, that killed 49 people and injured 58 others in June 2016.

The Vegas shooting occurred shortly after 10 p.m. PT Sunday during a Jason Aldean performance on the final night of the three-day Route 91 Harvest festival, held in a lot across Las Vegas Boulevard from the Mandalay Bay hotel.

Fans dove to the ground and took cover, trying to protect themselves as bullets flew through the air from the higher vantage point for what witnesses estimated to be 10 minutes.

Lombardo said authorities also located Marilou Danley, earlier described as a “companion” of Paddock but ruled her out as a person of interest in the case. “We have located  her out of the country,” he said early Monday. “He was utilizing some of her identification and we’ve had a conversation with her and we believe her — at this time — not to be involved.”

“Tonight has been beyond horrific,” Aldean wrote on Instagram. “I still don’t know what to say but wanted to let everyone know that Me and my Crew are safe. My Thoughts and prayers go out to everyone involved tonight. It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night. #heartbroken#stopthehate”

One person tweeted images of hundreds of concert goers lying down on the ground to avoid gunshots. (Warning: This and all future videos are disturbing.)

Another video recorded the sound of many rounds being fired.

The situation diverted flights from the city’s McCarron Airport, airport officials tweeted.
