Stephen Paddock's room is now roped off with police crime scene tape. Down the hallway, a room service tray of food is discarded. Through a crack in the door, one of Paddock's weapons can be seen.
The 64-year-old stayed in the Vista Suite, which boasts 1,700 square feet of space with a wraparound view overlooking the Vegas strip.
Somehow, Paddock snuck in 23 guns in 10 pieces of luggage without housekeeping ever raising a red flag.
More is also being learned about how the massacre was staged.
Paddock used a hammer to shatter the floor-to-ceiling windows. Then he opened fire into the crowd at the 15-acre concert site 32 stories below, using a two-legged bipod and a gun platform.
The killer apparently fitted a special shoulder stock to increase the rate of fire of his semi-automatic weapons.
