Although mass murder is traditionally examined as a separate construct from homicide generally, few studies have explored their similarities and differences. This study compares the incident, victim, and offender characteristics of: (1) mass murderers and homicide offenders; and (2) mass murder-suicide offenders and homicide-suicide perpetrators. Mass murderers are more likely to be male; commit suicide; kill young, white, and female victims; use firearms; co-offend; operate in public places; and kill as part of drug trafficking and/or gang warfare. The analysis demonstrates that mass murderers are distinct from both homicide and homicide-suicide perpetrators, and represent a unique type of violent offender.

尽管传统上将大屠杀作为与杀人罪分开的单独结构进行研究，但很少有研究探索其相似之处和不同之处。这项研究比较了以下事件，受害者和罪犯的特征：（1）大规模杀人犯和凶杀罪犯；（2）大规模杀人自杀的罪犯和杀人自杀的罪犯。大规模杀人犯更可能是男性。自杀; 杀死年轻，白人和女性受害者；使用枪支；共同犯罪 在公共场所操作；并作为贩毒和/或帮派战争的一部分进行杀戮。分析表明，大规模杀人犯与凶杀和自杀自杀的犯人不同，是独特的暴力罪犯类型。
