A woman from upstate New York survived Sunday's massacre in Las Vegas with her daughter, telling reporters the horrifying event "seemed like it was never-ending."

Jennifer Bryan, who lives in Webster, NY in Monroe County, told Rochester's ABC affiliate that she had taken her daughter to the Route 91 music festival as a 21st birthday present. The two were near the stage on Sunday night when Stephen Paddock, 64, opened fire. "We saw a girl go down right behind us, probably 10 feet away, so I knew we couldn't sit there. We had to move," Bryan said.

Bryan and her daughter fled into a nearby tent, and Bryan lay across her to shield her from the bullets, pulling a piece of metal over both of them as protection. "He just kept reloading and reloading and reloading — it just seemed like it was never-ending," she told the outlet. Investigators say Paddock fired for between nine to 11 minutes after the first 911 call came in.

She said she hasn't slept since Sunday's attack. So far, 59 people have been confirmed dead, making it the deadliest mass shooting in modern history. The deadliest mass shooting in U.S. history to date is still the Wounded Knee Massacre of 1890, when 150 to 300 Native Americans were slaughtered by the U.S. army in South Dakota.
