Chilling toll of the mass killers
THE Las Vegas slaughter is the worst in a list of US shootings with huge death tolls.
Omar Mateen, 29, killed 49 in a gay nightclub in Orlando in June last year.
At Virginia Tech in Blacksburg, student Seung-Hui Cho, 23, went on a rampage in April 2007, slaughtering 32. And at Sandy Hook school, Newtown, Connecticut, in December 2012, Adam Lanza, 20, killed 20 pupils aged six and seven, and six adults.
Since 1966 there have been 12 gun rampages in which a dozen or more died.
