New York University (NYU) students attend a vigil for the victims of the mass shooting in Las Vegas, on October 2, 2017 in New York. The death toll from the deadliest mass shooting in US history rose to 58 on Monday as officials reacted cautiously to an Islamic State claim of responsibility for the massacre at a concert on the Las Vegas Strip. Police said Stephen Craig Paddock, 64, a wealthy former accountant, smashed windows in his 32nd floor hotel room Sunday night and trained bursts of automatic weapons fire on concert-goers below. / AFP PHOTO / Jewel SAMAD
