Police are working to establish the motive behind a mass shooting which left at least 59 dead and another 527 injured in Las Vegas. Gunman Stephen Paddock opened fire from the 32nd floor of the Mandalay Bay Hotel towards an open-air music festival. Police found 23 guns in his hotel room, as well as "in excess of" 19 firearms and explosives at his Nevada home. As yet, no clear reason for the killing has emerged. But Las Vegas Sun reporter Adam Candee tells us stories of heroism are emerging about those at the concert.
