Oral history interview with David Becker conducted by Claytee D. White and Barbara Tabach on May 15, 2018 for the Remembering 1 October Oral History Project. In this interview, Becker recalls being on a three-day assignment at the Route 91 Harvest Country Music Festival across from the Mandalay Bay Resort in Las Vegas, Nevada. Thinking the gunfire was produced by malfunctioning equipment, he took photos of the scattering crowd. Moments later, in a now silent venue, he realized he captured a horrific massacre. Becker recalls photographing people leaving the venue as they performed acts of heroism, helping the fallen or the slow to reach safety. He discusses how difficult it is to comprehend the acts of that night, and how his photojournalist instincts allowed him to capture such devastating images.
