Police are working to establish the motive behind a mass shooting which left 59 people dead and another 527 injured at a Las Vegas concert.
Gunman Stephen Paddock, 64, had opened fire from the 32nd floor of the Mandalay Bay Hotel towards an open-air music festival on 1st Oct.
Police found 23 guns in his hotel room, as well as firearms and explosives at his Nevada home.
But as yet, no clear reason for the killing has emerged.
Investigators have found no link to international terrorism, despite a claim from so-called Islamic State (IS). Some investigators have suggested Paddock had a history of mental illness, but there is no confirmation of this.
