On Tuesday, officials offered new information on Paddock and how he planned the attack. An agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) said that 47 firearms had now been found in three different locations, including the hotel room, and Verde and Mesquite, Nevada.
Of those weapons, 12 had devices known as bump stocks attached that allowed semi-automatic rifles to mimic fully automatic gunfire. The agent, Jill Snyder, said officials had determined the devices were legal. The weapons – rifles shotguns pistols – were purchased in Nevada, Utah, California and Texas, she said.
