Witness says woman told Las Vegas crowd 'you're all going to die' 45 minutes before shooting

In the aftermath of the worst mass shooting in recent US history, one witness to the shooting said a woman had apparently warned the crowd that they were "all going to die tonight."

A concertgoer who attended the Route 91 Harvest Festival where the shooting took place told Sky News that she saw "a lady who pushed her way forward into the concert venue into the first row."

The witness said "she started messing with another lady and told us, 'You're all going to die tonight,'" before being escorted out by security about 45 minutes before the shooting.

After that, the witness said she left the concert and headed back to her hotel room. When she heard there had been a shooting, she "thought it had a positive correlation to" the woman's warning.

It is unclear if the incident had any relation to the shooting, however. The witness described the woman and a man as "Hispanic" and "five footers."

"They just looked like everyday people," the witness said.

Police have identified Stephen Paddock, a 64-year-old white male, as the suspected gunman.

His roommate, Mailou Danley, was an initial person of interest to police. Police have now said she was out of the country.

The shooting left more than 50 dead and 400 taken to the hospital. It is believed to be the deadliest mass shooting in modern US history.
