The Las Vegas hotel room of gunman Stephen Paddock, who killed 59 people and wounded more than 500 at a country music concert, was littered with assault rifles and bullet shells, photos of the room show, according to Daily News.

Boston 25 News reporter tweeted a photo of Paddock’s room that shows a hammer along with dozens of casings on the floor and a bullet magazine. Among the casings is an assault rifle fixed with a scope and bipod.

A second photo showed another long assault rifle with a long magazine and handle at the front of the stock.

Police believe Paddock used a hammer to bust a window in his Mandalay Bay Resort and Casino hotel room.

The room looked down 1,200 feet at the Route 91 Harvest festival, where about 22,000 people attended a Jason Aldean concert.

They found 23 firearms inside the 32nd floor room, where Paddock had killed himself before cops arrived. A handgun and 16 assault rifles were part of his horrifying arsenal, authorities said Monday. They believe he snuck them into the room a suitcase.

At one point, Paddock fired 280 rounds at the crowd in the course of 31 seconds.

Cops were able to find his room 20 minutes into the shooting because the tremendous amount of gunpowder triggered the hotel’s smoke alarms.

Paddock had been staying in the palatial suite since Thursday, police said.
