(Maquoketa, IA) — A published report says the suspected gunman in last month’s triple-murder at Maquoketa Caves State Park used a “ghost gun.” The Des Moines Registered quotes the parents as saying the 23-year-old suspect ordered parts for the untraceable weapon online and built it himself at home. Authorities say he used that gun to kill Tyler, Sarah Schmidt, and their daughter, Lula. The victims were in their tent at the park at the time. There is no known motive for the killings. The alleged gunman later turned the weapon on himself and his body was found nearby.
