Stuart (surname unknown) is the British boyfriend and accomplice of George Buckley. Buckley was the secretary of Emily Huntford, who the couple tried to extort for 2 million dollars when her great-niece Emma went missing.
Stuart escaped with the money, but as his British English choice of speech was recognized in the ransom calls, the couple were tracked and arrested. Stuart was found guilty of extortion, robbery, and fraud along with Buckley and was imprisoned. (CI: "Folie à Deux")
