Oral history interview with Stephen Round conducted by Claytee D. White on October 25, 2017 for the Remembering 1 October Oral History Project. In this interview, Stephen A. Round, a career military contractor, describes his experiences during the 2017 mass shooting in Las Vegas, Nevada. Round mentions moving to Las Vegas in 2013 and in later years staying at the Aria on the evening of October 1. He describes the chaos of the shooting and the 12-hour-plus lockdown at the Aria hotel and casino. The day after the shooting, Round built a memorial around the shooting site and protected it. Once the memorabilia of that first site was taken to the Clark County Museum, he moved to protect the second memorial at the "Welcome to Las Vegas" sign where crosses devoted to the victims had been placed. Along with his preservation of the memorials, Round describes his preparation of a book that was signed by many who visited the sites. Round explains that he was able to see some of the best and worst of humanity during those days of watching and caring for the memorial sites as well as helping any victims, families of the victims, and sympathizers of the Las Vegas 2017 shooting.
