New aerial photos show aftermath of Las Vegas shooting scene

Jason Aldean was playing at a country music festival when gunfire rang out.

The photos were taken from ABC affiliate KTNV-TV's chopper.

Photographer Brandon O'Neal, who was backstage during Aldean's performance, said it became total panic and confusion as the sound of rapid gunfire echoed throughout the venue.

“We had no idea if there were people in the venue with guns or if they were from the hotel,” he said. "We had no idea where to go.”

Fifty-eight victims were killed, making Las Vegas the deadliest shooting in modern U.S. history.

Police said Paddock, 64, had stockpiled weapons in his Mandalay Bay hotel room. He was found dead when authorities stormed his suite.

The motive remains unknown but police say the attack was "obviously premeditated."

Police also say Paddock may have planned to escape the scene.
