It took nine to 11 minutes of gunfire for Stephen Paddock to carry out the deadliest mass shooting in modern US history.
From his 32nd-floor window at a Las Vegas hotel, Paddock fired a barrage of bullets at 22,000 concertgoers below — an attack that appears to have been meticulously planned.
The gunman checked into the room days in advance, stocked a cache of weapons there and set up cameras inside his hotel suite and in the hallway.
The first call reporting shots fired came at 10:08 p.m. Sunday, and the gunfire didn’t stop until at 10:19 p.m., Clark County Undersheriff Kevin McMahill said. The shooting went off and on for nine to 11 minutes, he said.
The massacre left 58 people dead and another 500 people with gunshot wounds or stampede injuries.
No one knows why Paddock decided to spray gunfire on the crowd at the Route 91 Harvest festival.
But authorities are hoping to find answers when Paddock’s girlfriend, Marilou Danley, is questioned. She returned to the United States Tuesday night from the Philippines and is being accompanied by the FBI in Los Angeles, where Las Vegas police plan to question her, a law enforcement source told CNN.
Police believe Paddock acted alone. But the motive remains a mystery.
“There’s all kinds of things that surprise us on these kinds of events, that’s the one on this one,” FBI Deputy Director Andrew McCabe told CNBC. “This individual … didn’t leave the sort of immediate thumbprints you find on these kinds of attacks.”
The gunman had an arsenal of weapons in his hotel suite, including bump-fire stocks — legal devices that enable a shooter to fire bullets rapidly, similar to an automatic rifle.
