Erick Steven Silva was 21 and working as a security guard for Contemporary Services Corporation at the Route 91 Harvest festival in Las Vegas on October 1, 2017. Stationed in front of the stage amid thousands, he remained at his post when gunfire erupted and helped concertgoers climb over a barricade to reach safety. Witnesses and colleagues say he shielded and guided people during the attack and was fatally struck by a bullet while doing so.

Silva’s actions are credited with saving numerous lives during what became the deadliest mass shooting in modern U.S. history. The shooter was later found dead from a self-inflicted wound in a hotel suite; no arrests were made in connection with the attack and investigators have not determined a clear motive.

Did anyone at the festival know Erick or have memories of his actions that could add to the record?
