Las Vegas shooting death toll rises to 59, no apparent connection to international terror

— -- At least 59 people were killed and 527 injured in Las Vegas Sunday night when a gunman opened fire on a music festival crowd from the 32nd floor of the Mandalay Bay Resort and Casino, in what is now the deadliest shooting in modern U.S. history.

The death toll from the incident could possibly go up, said Clark County Coroner John Fudenberg in a press conference Monday afternoon.

Jason Aldean was the headliner of Sunday night's concert; video showed him rushing off the stage amid the gunfire. Other performers from this weekend included country stars Jake Owen, Big & Rich, Luke Combs and Dylan Scott.
