The aim of this study was to differentiate between homicides committed by multiple offenders and homicides committed by lone offenders. Using data on homicide incidents that occurred in South Korea between 1985 and 2008, we compared 134 homicides committed by multiple offenders, with 369 homicides committed by lone offenders. A greater proportion of homicides committed by multiple offenders involved injuries to the victim's head compared to homicides by lone offenders. Homicides committed by multiple offenders were more likely to involve blunt instruments and ligatures, whereas homicides by lone offenders were more likely to involve sharp instruments. In addition, a majority of the homicides committed by multiple offenders were planned. The results of this study have practical implications for homicide investigations, as well as theoretical implications for homicide research on the difference in offense behaviors based on the number of offenders.
本研究的目的是区分多名罪犯实施的杀人案和单独作案的杀人案。利用1985年至2008年韩国发生的杀人事件数据，我们比较了134起多名罪犯实施的杀人案和369起单独作案的杀人案。与单独作案的杀人案相比，多名罪犯实施的杀人案中受害者头部受伤的比例更高。多名罪犯实施的杀人案更有可能涉及钝器和绳索，而单独作案的杀人案更有可能涉及锐器。此外，多名罪犯实施的杀人案大多是有预谋的。本研究结果对杀人案调查具有实际意义，同时也对基于罪犯数量的犯罪行为差异的杀人案研究具有理论意义。
