Samuel Colpepper is the main murder victim of So It Goes (episode). After his boss, Angus Clarke, uncovered evidence that his protégé, Gareth Godfrey, had arranged for six Naval officers to be killed in a manner that was made to look like an accident and replace them with Albanian-American members of the same Albanian mafia that he was running, he stayed behind in America, and was on his way over to the NCIS compound to deliver this information. While in Washington, he did a shopping spree and also planned to visit the Smithsonian.
