Leopold was last seen in Jewell, Iowa, on October 13, 2016. He was working his shift at W&G Marketing, a meat processing plant, when he left at 6:30 p.m., shortly before his lunch break. He informed his supervisor that he needed to retrieve his medication. However, he never returned to work and has not been heard from since. On October 16, Leopold’s truck was discovered on Canyon Road in Ledges State Park. The vehicle was unlocked, with the keys left in the ignition. Inside the truck, his work smock was draped over the steering wheel, and his work boots were found in the back. The truck had been parked there since at least October 15, as evidenced by a parking warning issued that day. Leopold’s family has expressed concerns that a mental health crisis may have contributed to his disappearance. Additionally, there have been unverified rumors suggesting foul play or potential drug involvement. Since his disappearance, there has been no activity on his cellphone or bank accounts.
