达拉斯ICE设施枪击事件致一名被拘留者死亡，两人受伤；嫌疑人自杀身亡
摘要
达拉斯ICE现场办公室发生枪击事件，导致一名被拘留者死亡，两人受伤，嫌疑人自杀；当局将此事件视为针对性暴力进行调查。
周三上午，美国移民与海关执法局（ICE）达拉斯现场办公室发生枪击事件，导致一名被拘留者死亡，另有两人重伤。嫌疑枪手为29岁的乔舒亚·贾恩（Joshua Jahn），因自残枪伤身亡。事件中无执法人员受伤。
袭击发生在上午6:40左右，枪手从高处向设施的安全转运区（sally port）开火，该区域用于转移被拘留者。国土安全部（DHS）将此事件描述为“对ICE执法人员的攻击”。
联邦调查局（FBI）负责人约瑟夫·罗斯罗克（Joseph Rothrock）特工表示：“我们早期获得的证据显示，在嫌疑人附近发现的弹壳上含有反ICE性质的信息。”
FBI正将此次枪击事件作为针对性暴力行为进行调查。此事件发生在近期德克萨斯州其他针对移民执法设施的袭击之后，包括7月4日阿尔瓦拉多拘留中心遭袭和7月7日麦卡伦边境巡逻设施枪击事件。
德克萨斯州州长格雷格·阿博特（Greg Abbott）表达了对ICE的支持，称：“德州公共安全部和德州国民警卫队与ICE密切合作。这次暗杀不会减缓我们逮捕、拘留和驱逐非法移民的步伐。”
当局继续调查袭击动机，并呼吁公众提供相关线索，以协助正在进行的调查。
