Jan Manders can’t accept the finding that her daughter’s death was an accident. She walks away on her daughter Jennifer’s fifth birthday and declines into substance abuse and mental illness. Jennifer and her older brother, Christopher, are pretty much left to raise themselves. Jan hires a private detective, Norbert Kurczewski, to investigate Michelle’s disappearance. Kurczewski tracks down a waitress and several patrons at a restaurant in Black Earth, about 70 miles away, who say they saw Michelle there during the time she was missing.

A couple of months before Michelle Manders disappeared, her mother Jan befriended a woman named Teri Mueller. Teri stayed at the Manders’ house one night when her husband failed to pick her up at 10 p.m. The next morning, both she and Michelle were gone. Two and a half weeks after Michelle disappeared, Teri tells police she opened the door for Michelle that night. They base their classification of accidental death largely on her statement, even though she has an intellectual disability and suffers from schizophrenia that sometimes causes delusions.

Two-and-a-half-year-old Michelle Manders disappears from her Watertown home in the middle of the night in October 1981. About three weeks later, her body is found in the Rock River, which winds through town.

Hers was the fifth in a series of strange disappearances and deaths in Jefferson County over a seven-year period. At first, police suspect she was abducted. But after her body is found, officials deem it an accidental drowning.

The district attorney at the time doubts that conclusion, and a review by the Journal Sentinel reveals shortcomings in the investigation.
