Fishing for the Truth - S9.E26

A two-man shrimp boat sank when a fast-moving, violent storm struck the Louisiana coast. The captain drowned, and the deckhand was rescued fourteen hours later. He told the Coast Guard that the captain's foot had become entangled in the fishing nets; they tried frantically to free him, but they failed. The deckhand was considered a hero until the captain's body was found. Eventually, the public discovers that he was coerced into confessing to the captain's murder.
