She has never been heard from again. After her disappearance, her car was found abandoned on Bolton Road in Freeport, Wisconsin, with her phone and belongings inside it. A month before Trumpy went missing, Hammer was charged with domestic abuse after Trumpy’s son told a teacher he saw Hammer hit his mother and threaten her wth a gun. A photo of Hammer is posted with this case summary. Trumpy had told a friend she was afraid of Hammer, and her three children stated she planned to leave him. He has not been charged in her disappearance or named as a suspect, but Trumpy’s loved ones believe he was involved. In May 2023, Hammer was sentenced to five years in prison for his assault on Trumpy and other offenses. Trumpy’s case is being investigated as a homicide. It remains unsolved.
