(Vancouver, WA) -- New details are coming to light regarding the police killing of a man holding a replica gun in Vancouver over the summer. Emergency dispatch audio files obtained by the Columbian show multiple witnesses told police the gun was just a replica before Officer Brandon Riedel shot and killed 43-year-old Vadim Sashchenko on June 8th. Police had responded to the area on reports Sashchenko's German shepherd was acting aggressive and had bitten several people. Calls to 911 stated Sashchenko was carrying a replica gun, and one witness at the scene could be heard shouting at officers, quote, "He's got a fake gun. That is a fake gun. That is not a real gun." The files also show responding officers discussing the possibility the gun was just a replica just moments before Riedel shot and killed him. Police did not reveal to the public that the gun was just a replica until weeks after the incident.
