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.
