New surveillance video of Stephen Paddock in the days before he killed 58 people from his hotel room window in Las Vegas shows nothing out of the ordinary, and that's what troubles Randy Sutton. "A guy who can order lunch knowing that he's going to kill people … that's not normal," the retired Las Vegas Metropolitan Police Department lieutenant tells CBS News, adding that Paddock's calm demeanor "is the true mark of a sociopath." NPR reports MGM Resorts says it released the surveillance footage "in the interest of providing greater context around Stephen Paddock's actions" in the six days he was at the hotel and casino prior to the October shooting. "As the security footage demonstrates, Stephen Paddock gave no indication of what he planned to do and his interactions with staff and overall behavior were all normal," MGM Resorts says in a statement.
The footage shows Paddock eating sushi, watching TV, visiting the hotel VIP desk, and gambling, appearing to prefer video screens to human opponents, CNN reports. Paddock is seen checking into his room, tipping hotel staff, and buying snacks. The footage from security cameras also shows Paddock repeatedly coming and going from his room with luggage. He brought 23 guns to the room in at least 22 pieces of luggage during his stay, but even then the footage shows him using different bellhops to avoid suspicion. The footage brings authorities no closer to discovering a motive for the shooting, and Sutton doesn't think they'll ever find one: "Why would a guy who supposedly has a fairly happy, successful life … has plenty of money, has a home, has a girlfriend … what goes on inside a brain like that that suddenly triggers a mass murder?"
