 Authorities suspected 61-year-old retiree Charles Smithart of the murder when another local man, Dave DeForest, told police he had observed Smithart driving near Mandy's house on the day she went missing.Police and forensic investigators found considerable trace evidence in Smithart's truck that suggested Mandy's presence in the vehicle, and learned from Smithart's eldest daughter that he had raped her and her sisters when they were Lemaire's age.In 1993, Smithart was tried for and convicted of first-degree kidnapping, first-degree sexual battery on a minor, and first-degree murder.
