Domestic homicide is the most extreme form of domestic violence. These deaths often appear to be predictable and preventable with hindsight, based on information from various death review process across the world. Prior research has identified citizenship status, length of stay, trauma and stress in the migration context as contributors to domestic violence. However, these factors have not been explored within the context of domestic homicide and the present study examined these factors among immigrant perpetrators.A retrospective case analysis approach was performed using domestic homicide cases that had been reviewed by the Domestic Violence Death Review Committee in Ontario, Canada. Perpetrators with a history of pre-migration trauma had significantly more identified risk factors for domestic homicide. Additionally, they were more likely to engage in stalking behaviours and have more identified post-migration stressors. However, the number of agencies involved did not significantly differ between perpetrators with or without a history of pre-migration trauma. Pre-migration trauma is a critical factor in understanding the risk profiles of immigrant perpetrators. Standardized risk assessment tools generally do not screen for pre-migration trauma and it may be overlooked by professionals when evaluating risk of homicide or when engaging in risk management strategies. It is imperative that professionals are more aware of the relationship between migration trauma and domestic violence perpetration and there is continued research and development of specialized risk assessment tools to aid in domestic homicide prevention initiatives.

家庭凶杀是最极端的家庭暴力形式。根据世界各地各种死亡审查过程中的信息，这些死亡往往是事后可预测和可预防的。先前的研究已经确定了移民状况中的公民身份，居留时间，创伤和压力是造成家庭暴力的原因。然而，这些因素尚未在家庭凶杀案的背景下进行探讨，本研究在移民肇事者中检查了这些因素。 使用安大略省家庭暴力死亡审查委员会审查的家庭凶杀案进行了回顾性案例分析方法，加拿大。有移民前创伤史的肇事者明显更多地确定了家庭凶杀的危险因素。此外，他们更有可能从事跟踪行为，并且有更多确定的迁移后压力源。然而，涉及的机构数量在有或没有移民前创伤史的肇事者之间没有显着差异。移民前的创伤是了解移民肇事者风险概况的关键因素。标准化的风险评估工具通常不会筛查移民前的创伤，专业人士在评估凶杀风险或参与风险管理策略时可能会忽略这一点。专业人士必须更加了解移民创伤与家庭暴力实施之间的关系，并且不断研究和开发专门的风险评估工具，以帮助预防家庭凶杀案。
