It's now the deadliest mass shooting in US history, and the current count of those injured is staggering, too: 400, per Las Vegas police. In a Monday morning news conference, Sheriff Joe Lombardo confirmed that more than 50 are dead and provided more details about shooter Stephen Paddock, whom Lombardo now says took his own life prior to the SWAT team entering his room (the Daily Mail has audio of the breach here) on the 32nd floor of the Mandalay Bay hotel; they found 10 weapons there.
Lombardo says police have turned up nothing "derogatory" in the 64-year-old Paddock's history, and no items in the room or his house shed any light on motive, reports the Guardian. Lombardo also said that Paddock checked into the room on Thursday. "I have no idea whether he prevented the house keepers from entering the room or not. That is a matter for continued investigation."
