达拉斯移民与海关执法局设施枪击案：枪手背景新细节曝光
摘要
新公布的记录揭示了袭击达拉斯移民与海关执法局（ICE）设施枪手约书亚·扬的背景，透露了他的心理健康问题及事发前的准备情况。
新公布的记录揭示了29岁枪手约书亚·扬的背景，他于2025年9月24日在达拉斯移民与海关执法局（ICE）设施开枪。扬杀害了两名被拘留者，另有一人受伤，随后自杀。
根据记录，扬的父母描述他在搬到华盛顿州之前是“完全正常”的。几年前返回德克萨斯州后，他认为自己患有辐射病，开始戴棉手套以避免接触塑料。袭击前大约一个月，扬在俄克拉荷马州用新购的步枪练习射击。
枪击当天，扬的父母向联邦调查局（FBI）透露他是个“孤僻者”，痴迷于人工智能技术。他们指出，扬未被诊断出任何心理或身体疾病，也未接受相关治疗。记录还显示，扬合法获得了用于枪击的栓动步枪。
联邦当局此前表示，扬在一颗子弹上写有“反ICE”的字样，并留下手写笔记，表明他意图伏击并恐吓ICE特工。调查仍在进行中，官员们试图了解袭击背后的动机。
达拉斯联邦调查局现场办公室负责人约瑟夫·罗斯罗克特别探员表示：“我可以确认，目前FBI将此事件作为有针对性的暴力行为进行调查。我们从在嫌疑枪手附近发现的弹药中看到的早期证据包含反ICE性质的信息。”
