Did Michael's Father Really Know Something About Samantha Walsh?

Samantha Walsh went missing from her home in the town of Leduc, Canada. The RCMP approached Michael Lewis' parents to put pressure on him to take a polygraph but he refused. By this point, locals had started to get angry, muttering amongst themselves that Michael Lewis was clearly the main suspect so why haven't the police done anything? A group of locals floated an idea that perhaps a group of them could go and try to speak with Michael's parents. Gordon Walsh: "I couldn't help but wonder, did Michael's father actually know something?"
