Police have identified the perpetrator of the worst mass murder in US history, which happened last night in Las Vegas at a country music concert. Reports so far are over 50 dead, over 400 wounded.

From the 32nd floor of the Mandalay Bay Hotel, the perpetrator, local resident Steven Paddock, was shooting concertgoers crowded together in the outdoor venue with automatic rifle fire which some have described as sounding like AK-47 fire. God Bless the victims and their families.

Authorities have identified 64-year-old Stephen Paddock of Mesquite, Nev., as the suspected gunman in the massacre that left at least 50 dead and more than 400 wounded Sunday night at a Las Vegas casino, according to The Daily Caller.

Paddock opened fire from the 32nd floor of the Mandalay Bay Hotel on the crowd of 22,000 gathered below to watch Jason Aldean perform at the Route 91 Harvest Concert. SWAT officers found him dead from a self inflicted gunshot wound after breaching the door to his hotel room.

Las Vegas Metropolitan Police Department (LVMPD) Sheriff Joseph Lombardo said Paddock, who was employed as an accountant, had a pilot’s license and a hunting license and no criminal record. Authorities found ten unspecified weapons in his hotel room and a camera system, which authorities believed Paddock set up to monitor their approach.

406 people were transported to the hospital including two on duty Las Vegas police officers. One unnamed off duty officer is among the dead, according to an LVMPD press release.

Police have located the suspect’s wife, Marilou Danley, a 62-year-old Asian female, believed to have been traveling with Paddock prior to the attack. They do not believe she was involved in the incident.

The suspect’s brother, Eric Paddock, said his brother had no history of mental illness or known political or religious affiliation.

There was “absolutely no indication he could do something like this,” Eric Paddock told the Daily Mail. “He was just a guy. Something happened, he snapped, or something.”

Meghan Karney described the horrific scene that unfolded after the shots began to rein down on the concert.

“We heard what sounded like firecrackers going off. Then all of a sudden we heard what sounded like a machine gun. People started screaming that they were hit… When we started running out there were probably a couple hundred [people] on the ground,” she told MSNBC.

“People kept dropping and dropping… People were getting shot one foot away from us,” she said. “People were trying to save their friends. There were gunshots everywhere. Helping them would’ve meant that we got shot too.”

Videos taken at the scene show mass hysteria as gun shots rang out and the band fled the stage.
