Cheryl A. Duvall, 38, was last known to be living on a dairy farm on South Parkview Road in Manitowoc, Wisconsin, with her boyfriend, John Neuser. She was a mother of two sons who lived with their father and visited their mother on weekends; her ex-husband reported her missing on October 1, 1988. Family and those who knew her described her as a good mother and said it would have been out of character for her to abandon her children.

After the initial missing-person report there was no confirmed contact: Cheryl’s Social Security number has not been used, and there are no records of law enforcement contact. The case went cold until a family member requested a reopening in 2006. In January 2007 investigators searched the South Parkview Road property and a second property in Cato where Neuser later lived; some items went to the state crime lab but testing was inconclusive. Neuser was named a person of interest but has not been charged.

Cheryl’s disappearance remains unsolved and the family has had few answers. Does anyone who knew Cheryl or her circle in Manitowoc in the late 1980s have information that could help explain what happened?
