Stephen Paddock prepared meticulously for the mass shooting in Las Vegas on Sunday, setting up a number of cameras in and around his hotel suite and adapting 12 semiautomatic rifles to mimic fully automatic gunfire, according to authorities.
Paddock, who killed at least 59 people and injured more than 500 at a Las Vegas concert, set up two cameras in the hallway and one in the peephole of his suite on the 32nd floor of the Mandalay Bay hotel so he could see “if law enforcement or security were approaching,” police said.
He also fitted so-called “bump-stocks” to 12 guns, allowing them to mimic fully automatic gunfire, according to Jill Snyder, special agent for the US Bureau of Alcohol Tobacco and Firearms.
Schneider said officers determined that “bump-stocks” were legal, as the weapons being used were still technically semi-automatic.
She added that Paddock had nearly 50 guns, including rifles, shotguns and pistols, in three locations.
Clark County Sheriff Joseph Lombardo told reporters that the deadliest shooting in modern US history was “pre-planned extensively.”
“This individual was premeditated. Obviously premeditated, the fact that he had the type of weaponry and the amount of weaponry in that room… I’m pretty sure he evaluated everything he did in his actions,” he said.
Undersheriff Kevin McMahill suggested the attack may have ended when Paddock, 64, was disturbed, shooting a security guard.
Paddock moved $100,000 (85,000 euros) into an account in the Philippines a week before the shooting on the country music festival, NBC News reported, citing senior law enforcement officials.
Paddock’s live-in girlfriend, Marilou Danley, who was abroad at the time of the attack, has family ties to the country.
It is unclear whether the money was for Danley, her family, or another purpose.
It comes as police released CCTV footage of Paddock in 2011.
