June 7 (UPI) -- Las Vegas Metropolitan Police released new surveillance video from the roof of the Mandalay Bay hotel and a nearby street that captured images of the Oct. 1 shooting at the Route 91 Harvest music festival.
More than 500 audio files of 911 calls from the massacre that killed 58 people and injured hundreds more were also released through a court order Wednesday.
The soundless video shows people running, then stopping and ducking, then sprinting again across the grass, as some stop to help the wounded. The 911 calls reveal sounds of chaos, agony and confusion as dispatchers try to calm and instruct the callers.
The release is the fifth batch of records handed over as part of a court order for Las Vegas police to comply with requests to make police body-camera video, dispatch logs, witness accounts and officer reports available to the public.
Last month, more than 1,000 pages of documents were released that detail the shooting on the south end of the Las Vegas Strip as shooter Stephen Paddock opened fire on the country music concert.
Police have already released dramatic body camera footage from when they first arrived at the hotel.
Authorities are still trying to determine a motive for Paddock, who shot himself in the hotel room before police could apprehend him.
