 note = {Although there have been significant advances in the knowledge and understanding of serial murder, its exact etiology remains unknown. In particular, the effect of environmental influences is unclear. While some researchers stress the impossibility of predicting multiple murders from an understanding of early childhood events, others posit the importance of traumatic event(s) on the deve lopment of serial killers. However, even among those who have stressed on traumatic event(s), there are clear inconsistencies regarding the timing and types of such incident(s). This study investigates the childhood environments of 52 serial killers to see if there are any patterns that appear repeatedly among their environmental backgrounds and if so, when such factors have more damaging effects on the subjects. This preliminary research intentionally uses lay literature and Internet-based information that are normally overlooked by academic researchers.},
