Douglas August Nowak, 30, was last seen in Milwaukee, Wisconsin, on June 9, 1986. His mother reported him missing after he was not heard from again. At the time he vanished he was described as a white male, 6 feet 1 inch, about 185 pounds, with blond hair, blue eyes and wearing wire-rimmed eyeglasses.

Douglas was known to be dealing with unspecified mental health issues when he disappeared. Investigators have considered that he might have traveled after he was last seen, with unconfirmed suggestions he could have gone to Adams County, Wisconsin, to Minnesota or into Canada, but no evidence has ever placed him in those locations. The Milwaukee Police Department’s investigation has remained open for decades but has produced few answers.

Does anyone who knew Douglas, or who was in the Milwaukee or Adams County area in June 1986, have information that could help clarify his movements or whereabouts?
