Also, Raylan's boss Art found out that at the time of Drew Thompson's apparent death 30 years ago he was wanted in a sealed federal witness warrant, putting the search for Thompson under the purview of the Marshals. Raylan's first stop in the Thompson search is visiting Thompson's former wife. Eventually the US Marshals find out that the head honcho of a Detroit criminal organization (Theo Tonin) also wants to find Drew Thompson. According to the wife, Thompson saw Tonin kill a federal witness. Preacher Billy is killed while handling a rattlesnake.
