The massacre ended when police stormed a 32nd-floor hotel room overlooking the concert and the shooter, identified as Stephen Paddock, 64, killed himself, Clark County Sheriff Joe Lombardo said.

Lombardo said reports of multiple shooters and explosives were false. Some of the deceased were police officers, he added.
