New aerial photos show aftermath of Las Vegas shooting scene

— -- New aerial photos show was left behind at the Route 91 Harvest Music Festival as gunfire sent country fans scrambling for their lives on Sunday.

The venue's grounds, where country music fans were enjoying the final night of the three-day festival, remains littered with trash and belongings days after the massacre.

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

Suspected gunman Stephen Paddock fired into the crowd of more than 22,000 from across the street at the Mandalay Bay Resort and Casino as country star Jason Aldean was performing.

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.
