In the wake of last night's deadly mass shooting at Las Vegas country music fest Route 91 Harvest Music Festival, EDM DJ Marshmello has cancelled his show at Las Vegas' XS Nightclub, which was scheduled for tonight (10/2). He also urged anyone in Vegas to stay off the strip. See his tweets below.

The shooting left at least 58 dead and over 500 injured, making it the most deadly shooting in US history. The suspect is believed to be 64-year-old Stephen Paddock, who killed himself after the shooting.
