(Cassel & Bernstein, 2007). What causes a person to commit such crimes and is it solely caused by psychological errors in one’s mind?
Brain injury is one example that could explain how somebody becomes a serial killer.
In the 1970‘s, John Wayne Gacy killed 33 young men across Chicago. There are of course some ‘logical’ explanations for these prolific murders which spaced over 3 years. Firstly, anger towards his father that led him to capture and murder young boys. He knew their weaknesses as young men and used them to his advantage. It was his inability to defend himself from his father’s attacks that led to this rampage of murders. It could have also been as a result of Gacy’s shame of being homosexual. He did not indulge in his sexual preferences and took the shame out on the young boys he took as his prey. Gacy soon became addicted to the manly power he possessed when taking his victims’ lives. Some theorists however argue that an injury that occurred in Gacy’s childhood contributed to his behaviour. When he was 11, he was struck in the head with a swing which caused a blood clot in his brain which was left undetected until he was 16. It is possible that this brain injury could have contributed to his change in behaviour and his hunger for power.
A counter argument for this is Ted Bundy. It was thought that by the end of his life had killed over 100 women in a tri-state murder spree. Bundy had parental issues as he grew up believing his grandparents were his parents and his mother was his sister, he also never knew his father which some theorists argue to be a factor
