Intimate partner homicides (IPH) are serious offenses by a heterogeneous group of offenders with diverse risk factors that are too unspecific for the successful prediction of an offense. Recent research suggested several warning signs that may precede IPH and enhance its prevention, but little is still known about “leaking.” Leaking comprises all offense-related statements, behaviors, or actions that express the perpetrator’s thoughts, fantasies, ideas, interests, feelings, intentions, plans, or positive evaluations of an own violent act or previous similar offenses prior to the own attack. This review aims to identify the forms, recipients, and media of leaking as well as potential subgroup differences in cases of IPH. We identified 47 relevant publications via a systematic search of eight databases and additional methods. We included publications that did not explicitly use the term, but described behaviors that could be interpreted as leaking. Up to now, leaking has not been systematically researched in cases of IPH. Nevertheless, publications described several behaviors that are in line with our definition of leaking and were categorized into five broader categories: (a) homicide announcements, (b) previous severe acts of violence, (c) suicidal behavior, (d) planning activities, and (e) interest in similar offenses/offenders. Information on recipients and media as well as subgroup differences was sparse. Leaking is relevant in IPH, but more systematic research is needed to understand its potential role in future risk analyses procedures and prevention of IPH.

亲密伴侣凶杀案的泄密：系统回顾

亲密伴侣凶杀案 (IPH) 是由一群异质犯罪者实施的严重犯罪行为，其风险因素多种多样，这些因素对于成功预测犯罪而言过于不具体。最近的研究提出了一些可能先于 IPH 并加强其预防的警告信号，但对于“泄漏”仍然知之甚少。泄密包括所有与犯罪相关的陈述、行为或行动，表达犯罪者的想法、幻想、想法、兴趣、感受、意图、计划或对自己的暴力行为或在攻击之前的类似犯罪行为的积极评价。本次审查旨在确定泄露的形式、接收者和媒介，以及 IPH 病例中潜在的亚组差异。我们通过对 8 个数据库和其他方法的系统检索，确定了 47 篇相关出版物。我们纳入的出版物没有明确使用该术语，但描述了可能被解释为泄漏的行为。迄今为止，IPH 病例中的渗漏尚未得到系统研究。尽管如此，出版物描述的几种行为符合我们对泄密的定义，并被分为五个更广泛的类别：(a) 杀人公告，(b) 以前的严重暴力行为，(c) 自杀行为，(d) 策划活动， (e) 对类似罪行/罪犯的兴趣。有关收件人和媒体以及亚组差异的信息很少。泄漏与 IPH 相关，但需要更系统的研究来了解其在未来风险分析程序和预防 IPH 中的潜在作用。
