Tipster Sharon Blasing gives police some of her ex-husband James Dunn’s books, which discuss black magic and the practice of baptizing Satanists with water in which un-baptized children have drowned. Police eliminate Dunn as a suspect in Michelle’s death when they realize he was in jail at the time of her disappearance, but wonder if he was involved in the deaths of 19-year-old high school sweethearts Timothy Hack and Kelly Drew, who disappeared the year before Michelle. Flashback to a point earlier in the investigation into Michelle’s disappearance, when police suspected her mother could be involved.
