Officer Stewart was an FBI agent during the 1970s. In 1975, his colleague Will Graham was gravely wounded by Dr Hannibal Lecter, who had been exposed as a cannibalistic serial killer. FBI agents arrived at Lecter’s home to arrest him and to gather evidence. Stewart was the first officer to discover Lecter’s basement. Although not revealed to what he saw, it can be assumed that remains of Lecter’s victims or other trophies were stored there. Stewart soon retired, being traumatised by the ordeal. In 1978, Graham visited Lecter in hopes to capture the Tooth Fairy. Lecter remarked about Officer Stewart, saying he was a promising agent.
