As the death toll rises in the worst mass shooting in US history, photos are emerging of the destruction and tragedy of how the events unfolded.
At least 59 people have been killed and more than 500 injured after Stephen Paddock, 64, opened fire on a crowd at a Las Vegas country music festival.
Police said Paddock, a retired accountant, killed himself before a SWAT team entered his room in the Mandalay Bay Hotel overlooking the festival venue.
Las Vegas Sheriff Joseph Lombardo law enforcement were working four separate crime scenes: Paddock's room at the Mandalay Bay hotel, the concert venue, the gunman's house in Mesquite, and another house he owns in northern Nevada which a SWAT team was poised to raid.
Here are some of the photos of the chaos and the aftermath:
