The killer, 64, massacred 59 people from his hotel room at the Mandalay Bay in the worst rampage in the history of the US.

SWAT cops burst into his 32nd floor room and were met with the grim scene of 23 guns, ammunition littering the floor, and the dead Paddock.

Police also confirmed today the shooter had cameras hooked up into his hotel room.

Images have leaked showing Paddock lying dead on the hotel room floor with blood pouring from his mouth.

The gunman appears to be wearing a brown shirt, black slacks, loafers and a pair of gloves.

Chillingly, he appears to have left some kind of note on the side table.

Paddock’s motives remain a mystery, with the millionaire property developer having no criminal history.

He appears to have checked into the high roller hotel days before in a meticulous plot to kill.

A note left by the gunman may offer clues to his reasons for slaughtering country music fans at the Route 91 Harvest Festival.

Cops have repeatedly said investigations are ongoing and have yet to make public any details.

Graphic images – which Daily Star Online has chosen not the publish – show the close-up of the killer’s face.

His body lies splayed, with a revolver lying above him also stained with blood.

Other angles show a bipod mounted rifle at his feet.

Another weapon lies beneath his legs, and his body is surrounded with brass shell casings.

Pictures show a pile of magazines neatly stacked next to a column in the bedroom.

Weapons are scattered madly throughout the room, propped up against chairs and lying on sofa cushions.

It is believed Paddock obtained the guns legally, before modifying them himself for a faster rate of fire.

Explanations have been offered for his motive, but law enforcement has remained coy.

It has been suggested debts, a relationship collapse, or his family history may have contributed to the his drive to kill.

ISIS claimed responsibility for the Vegas slaughter – but the FBI rubbished this boast.

Paddock is understood to have racked up huge gambling bills before the shooting spree yesterday.
