Addie Sparks was a young girl who was kidnapped and murdered by John Lee Roche in June 1975. She was taken from her home in King of Prussia, Pennsylvania. In a dream sequence, Fox Mulder was led to her grave, which he and Scully found to be real. They informed her father, Frank Sparks, of their discovery. Like all of Roche's victims, a cloth heart had been cut out of her clothing as a souvenir. (TXF: "Paper Hearts")
