Dozens killed, more than 500 hurt in Las Vegas mass shooting

Gunman Stephen Paddock kills himself in hotel room

DETROIT – At least 59 people were killed and more than 500 were injured Monday in what's become the deadliest mass shooting in modern U.S. history.

Police said Stephen Paddock, 64, was the lone gunman who opened fire from the window of his hotel room on the 32rd floor of the Mandalay Bay in Las Vegas. His target was a packed country music concert below.

Panic and chaos took over the Las Vegas strip as Paddock opened fire and hundreds of rounds rained down from the 32 floor of the hotel.

"Everyone dropped, and everyone just got up, and everyone said, 'Run,'" a witness said. "Everyone started charging and stampeding."

Nevada Gov. Brian Sandoval compared the scene to a war zone as people dove for cover. The horrific attack came on the last night of the Route 91 Harvest Festival.

"We were laying down on the floor," witness Sarah Haas said. "I didn't know to get up, to run, to stay, to duck. I didn't know if it was safe to move."

Heavily armed SWAT teams moved in and cornered the gunman, who killed himself as they burst through his hotel door.

"Their selfless actions saved the lives of hundreds of people," said Steve Sisolak, the Clark County commissioner.

Paddock lives in Mesquite, Nevada. Authorities said he acted alone.

"This is a crazed lunatic full of hate," Las Vegas Mayor Carolyn Goodman said. "We don't know much about his background."

Inside Paddock's hotel room, police found multiple weapons.

Paddock's family was shocked by the incident.

"There's no affiliation that I know of at all," said Eric Paddock, Stephen Paddock's brother. "There's no church. There's no religion. There's no politics. There's no anything."

President Donald Trump called the attack "an act of pure evil."

Trump pledged the full support of the FBI and Department of Homeland Security to help in the investigation.

"To the families of the victims, we are praying for you and we are here for you," Trump said. "We ask God to help see you through this very dark period."

Trump said he will travel to Las Vegas on Wednesday to meet with first responders and families of the victims.

"It was the scariest time of my life," witness Sydney Sievers said. "I thought it was over."

But for many people, the trauma, like the investigation, is just the beginning.
