A woman in the crowd screamed 'They're all around...You're all going to f***ing die today' just 45 minutes before a gunman opened fire at a Las Vegas music concert killing at least two people and injuring dozens more, DailyMail.com has learned.

The woman, described as Hispanic and in her 50s, made the terrifying outburst before her and a male companion were escorted out of the venue by security.

Less than an hour later automatic gunfire peppered the music festival crowd turning it into a bloodbath and sending terrified concert goers diving for cover.

Police say they are now hunting for a woman named Marilou Danley, who they described as Asian, saying she has information that could help their inquiries.

Brianna Hendricks, who is in Vegas celebrating her 21st birthday, said: 'There was a lady who came running up behind us in the concert and she started to play with people's hair acting crazy and she told us that we're all going to f***ing die.

'She said they're all around us and we were going to die.

'She was Hispanic, probably about 5ft 5, brown hair. It felt like she had knowledge of what was about to happen, her and her boyfriend who was also Hispanic.

'The woman was saying her boyfriend couldn't breath so they could get through the crowd. It seemed she was telling us to either warn us or she was part of it and she was telling us because she knew we were going to die, it was so scary.'

Brianna from Springfield, Colorado, was interviewed by police at a police cordon not far from Mandalay Bay.

It's not clear whether what she witnessed is related to the shooting or not.

Her and her mother, Shawn Hendricks, had returned to their room at the Mandalay Bay shortly before the shooting began and were evacuated shortly after.

Brianna added: 'It was terrifying, we witnessed the shooting from our room, we heard constant gunfire.'

In among crowds at the country festival another witness who was in his room on the 32nd floor of the Mandalay Bay when the shooting erupted described the moment hundreds of rounds were fired from a nearby room.

The man, who asked not to be named, said: 'I was in room 135 and I heard over the police scanner that the shooting came from room 137.

'It was non-stop, I would say well over 100 rounds. We hit the floor and took cover.

'I called the front desk and she was remarkably calm and said she was aware of the situation and told us to stay in our room.

'After around 10-15 minutes it just kind of stopped. You could smell the gun powder.

'Right before we got out I heard an explosion, maybe a flash bang, but windows were blown out.

'The cops came on to the floor and they were clearing rooms room by room and six or seven cops came into our room and we were evacuated.'

Other sobbing concert goers told DailyMail.com that the gunfire was so intense, it sounded like 4th of July.

Derek and Karen Bernard, from Los Angeles, California, were in town for the Route 91 country festival and were close to the stage when the shooting began.

'We were inside,' said sales manager Derek, 53. 'All of a sudden, we saw the band disappearing - they were like running off the stage.

'We were off to the left side of the stage, we were running off there and there were staff security there.

'There was a woman bleeding - that's when we realized it was real shots. She just fell. She was shot. There was a lot of blood.

'It was so many - it sounded like 4th of July - just pop, pop, pop, pop, pop. So many. I didn't think it was real because I couldn't see or feel anything. I was so panicked.'

Wife Karen, a retired teacher, added: 'We heard shots fired, it sounded like firecrackers. We thought it was part of the concert.

'People were saying get down, get down and so we did. It was like mass havoc, panic, people were trampling over each other trying to get down.

'People were saying get behind the stage, get down and we crawled behind the stage. The shots they started coming much louder and closer.'

Describing their escape, she added: 'We jumped behind the stage. Someone made a ramp up to the top of the wall - we crawled, jumped and they caught us. We didn't know where to go. There was just an exodus of people.'

The couple said they were with a group of 14 friends who all ended up getting split up. All of them are accounted for and understood to be safe.
