RESUMO
The worldview that portrays a serial killer as being a white male an evil monster with unusual appearance having dysfunctional behaviours and relationship, engaging in animals torture or being sexually abused in childhood and therefore sadistically killing a targeted or specific population for sexual gratification should be challenged (Bearby-2004) Every serial killer drives to kill multiple victims which may be unique, dependent on his/her childhood history and experiences We try to find out commonalities and differences between them as route to identify possible life events and factors that converted a normal man into serial killers Following factors were identified Ÿ Stress and trauma Ÿ Need for belonging and loneliness Ÿ Power or Control Ÿ Low self-esteem Ÿ Sexually sadistic and violent pornography Ÿ Parents relationship pattern Ÿ Neurodevelopment complication
