The Case Against William Perry

Perry was investigated by police at the time of the murder due to his history of stealing and his relationship with the Wallaces. His alibis for both the night of the phone call and the day of the murder, they hold up until his death in 1980 when it's discovered that his alibis were fabricated. So overall, the case against Perry is considered much stronger than the case against William. But sadly, the case remains unsolved.
