Newly released cellphone video shows people running from a Las Vegas concert on Sunday while gunfire rained down from the 32nd floor of a nearby hotel.
Raymond Page, who shot the video, can be seen moving towards the Route 91 music festival venue as people streamed past him, some wounded. He can be seen stopping to help people who had been shot and can be heard shouting to people to keep their heads down and run.
After encountering a man who said he was shot in the arm, Page got his truck and returned to pick up wounded people and take them to the hospital.
The shooting was the deadliest mass shooting in modern U.S. history, killing 58 people.
