Bonnie Marie Repinski was 33 when she disappeared from the Town of Menasha, Wisconsin, on August 12, 1975. Recent separation from her husband left her staying with a sister while pursuing a divorce; she left behind three children and all of her personal belongings. On the day she vanished her estranged husband, David Repinski, took her out to mark her birthday and to talk about the divorce. They visited several taverns in Neenah and Oshkosh and were driving back to her sister’s home when, after an argument, Bonnie asked to be let out near the intersection of U.S. 41 and State Route 150. David last saw her walking toward her residence and she has not been seen since. Authorities suspect foul play and investigators say the case remains unsolved. New DNA technology and witness information have given hope that the case may still be solved — anyone with information should contact the Winnebago County Sheriff’s Office.

Did anyone in the area at the time see Bonnie that night or recall details about the couple’s movements that could help investigators?
