Chilling footage shows Las Vegas shooter's final massacre preparations

Video has emerged revealing the final movements of Las Vegas gunman Stephen Paddock just days before his deadly shooting claimed 58 lives.

CCTV footage, obtained by the New York Times, shows Paddock repeatedly wheeling suitcases to his room, amassing at least 21 items of luggage over a seven day period.

Staff at the Mandalay Bay Resort and Casino can be seen helping Paddock take his bags from his car to his 32nd floor room, oblivious that over 20 rifles and ammunition were inside the luggage.

At one point, staff help Paddock take seven bags to his room in one go. The casino's owner has defended the staff for not voicing concern over the large amount of baggage saying guests regularly bring large amounts of baggage to the hotel.

Following his arrival at the hotel on September 20, the never-before-seen footage shows Paddock eating sushi, watching television and even celebrating a $1000 win at one casino.

He can be seen chatting with hotel and casino staff, seemingly at ease ahead of his planned massacre.

Days later on October 1, Paddock used his newly assembled arsenal to fire more than 1,100 bullets onto the crowd the Route 91 Harvest Music festival below, leaving 58 dead and over 800 injured.
