New photos have emerged from the mass shooting that took place at the Mandalay Bay Resort and Casino in Las Vegas on Oct. 1, 2017, according to TMZ. The Las Vegas Police have released an 81-page preliminary report on the massacre, which reveals disturbing images on how the shooter, Stephen Paddock, concealed cameras, and turned his hotel room into an  armory. There are also photos of his dead body.

The images uncover how Paddock set up the mass murder, by hiding a camera in a food cart outside his room, and affixing a camera to the peephole on his door—the photos also show the window he broke from where he aimed and shot his assault rifle. His room was also filled with dozens of automatic weapons.

Paddock opened fire shortly after 10 p.m. PT, during the Route 91 Harvest music festival, which took place on the Las Vegas Strip. Perched on the 32nd floor of the hotel, he shot into the crowd for around 10 minutes. The gunman, who was 64-years-old, killed himself after carrying out the shooting. With 58 people killed that day (59 including Paddock), and 500 more injured, it is known as the deadliest mass shooting by an individual in U.S. history.

Following the shooting, police searched Paddock’s home in Mesquite, Nevada and found over a dozen firearms, multiple explosives, and thousands of rounds of ammunition. Prior to Las Vegas, the U.S.'s deadliest mass shooting took place in Orlando at the Pulse nightclub.
