Concert goers were told You're all going to f***ing die" less than an hour before the Las Vegas shooting started, it has been claimed. A woman in the crowd is said to have yelled the warning about 45 minutes before the Route 91 Harvest festival became the venue for the worst mass shooting in US history. After her outburst, it was claimed, the woman and her male companion were made to leave the venue by security. Less than an hour later, an attack began that left at least 50 people dead. Witness Brianna Hendricks... said: "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. "It felt like she had knowledge of what was about to happen." Ms Hendricks returned to the Mandalay hotel about 15 minutes before the shooting, and witnessed the subsequent carnage from her hotel room. She described the woman who gave the warning as "Hispanic, probably about 5ft 5, [with] brown hair", and said the woman's boyfriend was also Hispanic. The authorities have yet to comment on whether the woman's warning was just a bizarre coincidence, or whether it actually did have something to do with the mass shooting.
