Photos of the hotel suite used by the gunman who killed 58 people in Las Vegas on Sunday provide a glimpse of the arsenal of guns and ammunition that were in his possession.

Police officials confirmed the authenticity of the photographs of the scene at the gunman’s hotel suite.

From his perch on the 32nd floor of the Mandalay Bay Resort and Casino, the gunman, who was identified by the police as Stephen Paddock, used rapid-fire weapons to shoot at concertgoers at a music festival.

At least three AR-15-style rifles were visible on the floor and on the furniture, along with at least a dozen high-capacity magazines, which can hold up to 100 rounds. (A standard American infantry soldier's magazine is 30 rounds.)

AR-15-style rifles are a civilian variant of a standard service rifle used by the American military for more than a half-century. Unlike the military versions, they support only semiautomatic fire.

Two of the rifles were outfitted with medium-magnification scopes and two-legged supports, known as bipods, attached to the undersides of the weapons. These additions would have helped Mr. Paddock target specific individuals.

At least one of the weapons in the photographs appears to have been modified with a “bump stock,” a device that allows a semiautomatic rifle to fire rounds faster, at a rate similar to a fully automatic weapon. Officials said that 12 of the rifles found in the suite were outfitted with bump stocks. The diagram below only shows the location of the guns that were visible in photos and videos.

Mr. Paddock brought at least 10 suitcases into his hotel suite over a period of time, the police said. More than 20 guns and hundreds of rounds of ammunition were also found in the suite.

The suite was at the end of a hallway, with windows facing the concert grounds. A composite image of hotel photos, below, shows the layout and furniture of a similar suite with a different view. The image is flipped from its original perspective to match the orientation of the gunman’s suite.

Police officials said they found two video cameras in the hallway, including one on a service cart, and a third over the suite door’s peephole.

A hotel worker said that Mr. Paddock checked in on Thursday and kept the “Do Not Disturb” sign on his door for the next three days.

Mr. Paddock used a hammerlike device to break two windows on the 32nd floor, and he fired on the concertgoers about 400 yards away.
