After their deaths, Bruce became obsessed with the search for meaning in their loss. He thought perhaps the mythical Court of Owls was responsible, but he never found anything to prove it.[6] Troubled by grief, Bruce attempted to erase his memory with electroshock therapy, but chose not to go through with it, and to use his pain as a motivator.[7] At the age of 18, he used his relationship with Erin McKillen[8] - a daughter of the Irish mob, and with whom he attended Roxbury Academy[9] - to locate Joe Chill, and learned that he had simply needed the money, and there was no deeper meaning to his parents' deaths.[10]
