Pulse-Pounding Bodycam Footage Shows Officers Responding to Las Vegas Shooting

Playing Police Bodycam Footage Shows Response to Shooting: 'Is That Firecrackers?'

A sampling of heart-stopping footage recorded on police body cams, which show officers responding to Sunday's mass shooting, has been released by Las Vegas Metropolitan Police. 

Authorities arrived at a chaotic scene as Stephen Paddock unleashed a hail of bullets down 32 stories from his Mandalay Bay hotel room and into an unsuspecting crowd of concertgoers.

The first-person footage plays out like a video game with far higher stakes as officers attempt to ensure the safety of survivors and secure the area, despite mounting chaos and confusion.

Officers are heard screaming "Get down!" to terrified festival attendees as the seemingly unending barrage of bullets rings out overhead.

It's a nightmare that turned real for concertgoers and for the officers of the Las Vegas Metropolitan Police Department, who also released audio from dispatch radio recorded during the massacre.

"We've got shots fired ... at the Route 91. Sounded like an automatic firearm," an officer said early on in the assault. "It's coming from upstairs! From the Mandalay Bay. Upstairs at Mandalay Bay. Halfway up, I see the shots coming from Mandalay Bay — halfway up! We have an active shooter! We have an active shooter inside the fairgrounds!"

Minutes later, as reports came through of "many people down" in the festival, an officer reported being just one floor away from the shooter: "I'm inside the Mandalay Bay on the 31st floor. I can hear the automatic fire coming from one floor ahead, one floor above us," an officer said.

It was another several minutes before Paddock's room was found and he was discovered by SWAT members, dead from a self-inflicted gunshot wound. 

Before he took his own life, the 64-year-old was able to murder at least 59 people and injure more than 500.
