Sean Figueroa is a young volunteer named at an anti-illiteracy program called LIFA. When volunteering at the Sing Sing Prison, he met his mother's client Wade Crewes, and Sean taught the older man how to read. Eventually, Sean revealed to Crewes that he was his son. Crewes started to tell Sean about his work and even where he stashed the shoes he took and the pistol he used. He convinced Sean to kill for him. Later that day, Holmes and Gregson went to his mother Carla Figueroa's house, where they met Sean, who told them that Carla died a few years earlier of leukemia.
