Bodycam footage has captured the moment police entered the Las Vegas hotel room where a gunman unleashed the deadliest US mass shooting in modern times.
Hours of video has been released from two officers' cameras as they entered the Mandalay Bay casino on 1 October from where Stephen Paddock killed 58 people and injured hundreds at a music festival outside the hotel.
The pair entered the packed casino where people at the slot machines and the bar were unaware gunfire had been raining down from 32 floors above.
"You need to get everybody out of here," one officer told two hotel security guards.
"There's a shooter up there. He's killed multiple people already."
The video shows police checking every room on floors 29, 30 and 31 before they get to Paddock's suite on the 32nd.
An officer yelled, "Breach! Breach! Breach!" before there is a loud bang from explosives and a fire alarm sets off.
Inside the room, the bodycams show Paddock's body, with dark trousers and a long-sleeved shirt with a glove on his left hand, on his back, having killed himself.
Near his head there is a pool of blood on the carpet as a police SWAT officer walks past.
As more police enter the room, they talk about the number of firearms, with one saying there are at least 10 high-powered weapons.
"Did he have any scoped weapons over there?" an officer asked. "Oh yeah," another said.
Another says Paddock was "blasting out the window" while pointing to "a whole suitcase full of loaded AK mags," talking about the AK-47 rifle ammunition magazines.
Police then look behind curtains and one grabs an assault-style rifle from the ledge of a broken window, warning others to take care.
"I don't know what that is, but there's a wire there," the officer said before turning towards the door and adding: "He put cameras up on the peepholes and all that. That's what these wire are."
They agree it was set up so Paddock knew when officers were coming down the hallway.
The video shows the officers talking about whether there is evidence of a second shooter and finding Paddock's driver's licence.
The FBI later said they believe the 64-year-old retired accountant acted alone.
Police lawyers revealed the first officer through the door did not activate his bodycam, raising questions about whether officers followed department policy.
A police spokeswoman said nobody from the agency would comment on the videos, whether the first officer followed procedure or whether he had been disciplined.
Hundreds of hours of bodycam recordings were taken so the two and a half hours released on Wednesday evening do not show the whole picture.
Several media outlets sued the Vegas police department to obtain videos, 911 recordings, evidence logs and interview reports to reveal the emergency response as Paddock fired for more than 10 minutes.
The Nevada Supreme Court last week upheld a state judge's ruling that the records must be made public.
County Sheriff Joe Lombardo said the police investigation is still not complete but he believed releasing the footage would "further traumatise a wounded community".
"For that, we apologise," the elected head of the Las Vegas Metropolitan Police Department said.

"What is seen on those videos in no way changes the facts that we were able to clarify for you shortly after the crime."
He added that more recordings would be released in batches over the coming weeks.
