Paddock is also seen on the casino floor, riding an elevator and talking with valets, among other actions.
Authorities have said Paddock opened fire onto a crowd at the Route 91 Harvest music festival from a room at the Mandalay Bay on Oct. 1, 2017. He was found dead in his room from a self-inflicted gunshot wound a short time later.
Attorney Catherine Lombardo represents several Las Vegas shooting victims. She said the videos will likely play a key role in future lawsuits.
“Paddock knew that the Mandalay Bay was the perfect place to carry out this slaughter,” said Lombardo, adding: “Paddock knew that Mandalay Bay and MGM had subpar security and that he could walk right past them and that's exactly what he did.”
