Melissa Trumpy, a 37-year-old woman from Wisconsin, remains missing five years after her disappearance on October 26, 2021. She was last seen at the home of her on-again, off-again boyfriend, Derek Hammer, near Shannon, Illinois. Investigators later discovered her vehicle abandoned on Bolton Road in Stephenson County. Despite the passage of time, Carroll County Sheriff’s investigators assert that the search will continue until Trumpy is found. The case has drawn involvement from the Illinois Attorney General’s Office and various local, state, and federal agencies, who are actively reexamining evidence and pursuing new search warrants. Derek Hammer, who was arrested on October 27, 2021, on unrelated outstanding warrants, had previously been charged with domestic battery in Green County, Wisconsin, one month prior to Trumpy's disappearance. Benny Affrunti, the father of Trumpy’s two youngest children, expressed the profound impact the unresolved case has had on the family, noting that the children have never had the opportunity to say goodbye or hold a funeral. He highlighted the trauma the children endured, stemming from incidents involving Hammer. Investigators are urging anyone with information regarding suspicious activity on the night of October 26 or early October 27, 2021, to come forward.
