 note = {Mass murderers have received relatively little academic interest compared with serial murderers. Although a solid basis set for understanding mass murderers already exists , there seem to be certain inconsistencies in the understanding of the environmental backgrounds of mass murderers, especially from the viewpoint of the presence or absence of abuse, bullying, and isolation. This study examines the environmental background s of 28 mass murderers to see if there are some patterns that appear repeatedly. In particular, this study focuses on clarifying whether these patterns are neglect oriented, abuse oriented, or both and whether various factors are of equal importance in cre ating mass murderers. This preliminary research intentionally used lay literatures on true crimes and Internet-based information that are normally overlooked in academic research.},
