On the night of July 4, 1980, an evening of celebrations in the rural town of Anson, Maine ended in the murder investigation of a young local mother. Tire tracks at the scene raised suspicion and rumor, but despite the evidence and apparent confidence of investigators, years passed without any movement in the case. By the time it went to trial, Rita St. Peter’s case would be the longest standing unsolved homicide in the state of Maine. Yet the person believed to be responsible for her violent death had been at the top of the suspect list from the very first day of the investigation. This story is proof that even decades later, cold cases can be solved.
