Stephen Paddock, the Las Vegas shooter, had an arsenal of 17 weapons in his hotel room, mostly military-style rifles, according to a law enforcement source.
At least one of them had been modified with a legal “bump stock” style device that allows the shooter to rapidly fire off rounds without actually converting it to a fully automatic weapon, the source said.
The devices modify the gun’s stock so that the recoil helps accelerate how quickly the shooter can pull the trigger. The devices are legal in the U.S.
Bill O'Reilly, the disgraced former Fox News host who was fired after sexual harassment allegations, penned a blog post on his site about the massacre in Las Vegas that left at least 58 people dead.
"Once again, the big downside of American freedom is on gruesome display," the post on billoreilly.com begins.
"The murderer had a number of deadly weapons in his room and you can count on the gun control debate to ramp up," he wrote. He says he's covered many mass shootings and that gun control will not stop them from happening.
On Oct. 1, 2015, exactly two years before 58 people were killed and 515 more were injured during a concert shooting on the Las Vegas Strip, a gunman opened fire at the Umpqua Community College in Roseburg, Ore.
Nine died, not including the shooter, and seven others were wounded when Christopher Sean Harper-Mercer rounded up students in a classroom, asked if they believed in God, then killed them one by one before turning the gun on himself.
Stock prices of the biggest firearms companies jumped Monday as investors feared the mass shooting in Las Vegas could lead to tougher gun laws.
Gun sales have soared after previous mass shootings — and in response to other current events, including the election of Barack Obama and the death of Supreme Court Justice Antonin Scalia, who had defended a narrow interpretation of the 2nd Amendment protecting gun ownership.
American Outdoor Brands, parent of Smith & Wesson, had been trading down more than 25% so far this year. It closed Monday at $15.74, up about 3.2%.
Investigators found fully automatic guns among multiple weapons in Stephen Paddock's 32nd-floor Las Vegas hotel room, according to the top Democrat on the House Intelligence Committee, Rep. Adam Schiff.
The congressman from Burbank, who received a briefing from FBI officials in Washington on Monday, said he didn't know if the guns found in the Mandalay Bay Resort room were manufactured to be fully automatic or had been modified. Such weapons fire more than one round with each pull of the trigger.
Paddock killed himself as SWAT units converged on the room amid Sunday night's carnage, officials said.
