A Cadillac man could spend the rest of his life in prison after an investigation shows he provided a friend with drugs that ultimately killed her. The Traverse Narcotics Team began investigating in March after the 41-year-old Cadillac woman died at a Clam Lake home. Investigators say an autopsy shows the woman died from an overdose of cocaine and morphine. Witnesses fingered John Fleming who held a prescription for the morphine. 25-year-old John Fleming was charged on Monday for delivery of a controlled substance causing death.
