Las Vegas shootings: Paddock spent 20 years buying weapons, committed suicide after attack [PHOTOS]

Authorities have revealed that Stephen Paddock, the Las Vegas mass murderer, set up cameras in a door peephole and on a room service cart outside the room to alert him when police arrived.

After killing over 55 persons attending a music concert, SWAT teams blew the door off his room and found him dead inside.

Paddock, had over the course of more than 20 years, bought his weapons such as rifles, shotguns and handguns from Nevada, Texas, Utah and California legally.

Images that leaked yesterday show Stephen Paddock’s body on the floor of his suite in the Mandalay Bay resort and casino, which he used as a sniper’s nest on Sunday night to open fire on 22,000 innocent people attending a music festival across the street.

In the photos shared by MailOnline, only the 64-year-old’s legs, torso and left arm are visible and he wears a typical outfit for a retiree: a brown long-sleeve t-shirt, black slacks and slip on loafers with white socks.

The only thing that reveals his nefarious actions are the black gloves he’s wearing.

A SWAT team located Paddock in his room about 72 minutes after the beginning of the deadly attack – but cops estimate he only fired on the crowd for 9-11 minutes, starting at 10:08pm.

Police say he shot at officers as they broke the door, but by the time they made it into the suite, Paddock had committed suicide.

It was gathered that there were 23 firearms in the hotel room, including an AK-47, an AR-15-type gun, and a handgun.

Report further claims that Paddock had still more guns stored in his two houses in Verdi, outside Reno, and Mesquite, bringing the total across all the locations to 47, she said.
