The aim of this study is to investigate potential differences between homicide-suicide cases in which the perpetrator does or does not write a suicide note. As homicide-suicides are complex types of lethal violence for which the aggressor cannot be held accountable, suicide notes may be a valuable source of information about the background of these cases and the perpetrators' motives. We use a national sample of N = 288 homicide-suicide cases in Germany applying group comparisons and chi-square tests for relevant variables. Perpetrators killing their own children and perpetrators leaving children behind before killing themselves write significantly more suicide notes than other perpetrators. Even though note writers and no note writers are similar regarding most sociodemographic characteristics, other differences question the generalizability between these 2 groups.
本研究的目的是调查行凶后自杀案件中，行凶者留下或未留下遗书的潜在差异。由于行凶后自杀是一种复杂的致命暴力形式，行凶者无需承担责任，遗书可能是有关这些案件背景和行凶者动机的宝贵信息来源。我们使用德国全国范围内N = 288起行凶后自杀案件的样本，对相关变量进行组间比较和卡方检验。杀害自己孩子的行凶者以及在自杀前留下孩子的行凶者比其他行凶者写下遗书的比例显著更高。尽管写遗书者和不写遗书者在大多数社会人口统计学特征方面相似，但其他差异对这两组之间的普遍性提出了质疑。
