Terrance Gilroy is a victim of The Gravedigger, and is known to be their first victim. His burial and body were discovered many years after his death. The convicted Gravedigger killer used clues to lead the Jeffersonian team to his location as a taunt to them, believing that the discovery of his body would lead to the prosecutions against them to be dismissed, and freedom for The Gravedigger. Ironically, he was the vital key in locking away his killer, as he had bit his assailant, holding DNA evidence, which led to The Gravedigger's imprisonment.
