Robert Washburn's DNA on Jenny Bastion's Swim Suit

Robert washburn was the guy who phoned in a tip about michella's murder. He was never a suspect on her short list, only because of that genealogy analysis. The funny thing is that he was not a hygh priorty suspect. In fact, when investigators came knocking at his door, he voluntarily gave them a dna sample. More than three decades after that terrible day in the park, washburn was arrested at home.
