Charlie Kirk, the charismatic founder of the nation’s pre-eminent right-wing youth activist group, was fatally shot on Wednesday while speaking at Utah Valley University. His killing prompted grief from prominent media figures and outrage from officials of both parties, who called for an end to politically motivated violence.

美国首屈一指的右翼青年活动组织创始人、充满领袖魅力的查理·柯克周三在犹他谷大学演讲时遭枪击身亡。他的遇害引发知名媒体人士的哀悼，以及两党官员的愤慨，他们纷纷呼吁终结出于政治动机的暴力行为。

The F.B.I. director, Kash Patel, posted on social media a few hours after the shooting that the “subject for the horrific shooting today that took the life of Charlie Kirk is now in custody.” But at a news conference a few minutes later, Utah officials described an individual in custody as a person of interest who was being interviewed about the shooting, and said the investigation was ongoing to “find this killer.”

枪击事件发生数小时后，联邦调查局局长卡什·帕特尔在社交媒体上发文称，“今日造成查理·柯克死亡的恶性枪击案嫌疑人已被拘留”。但几分钟后，犹他州官员在新闻发布会上表示，被拘留者只是一名接受讯问的有关人士，并称“缉拿凶手”的调查仍在进行中。

Gov. Spencer Cox, Republican of Utah, described the shooting as a “political assassination.”

犹他州州长、共和党人斯宾塞·考克斯将此次枪击定性为“政治暗杀”。

President Trump mourned Mr. Kirk, 31, a close ally, in a post on social media. “The Great, and even Legendary, Charlie Kirk, is dead,” he wrote, adding, “He was loved and admired by ALL, especially me, and now, he is no longer with us.”

特朗普总统在社交媒体上发帖悼念他的亲密盟友、31岁的柯克。“伟大且堪称传奇的查理·柯克去世了，”他写道。“他受到所有人的爱戴和敬仰，尤其是我，如今他却与我们永别。”

Mr. Kirk was struck about 20 minutes after he began speaking on the university’s campus in Orem, Utah. The university said shortly after the shooting that a person had been taken into custody, but investigators later determined that the person who had been detained was not the gunman. Officials at the news conference said that person had been charged with obstruction of justice.

柯克在犹他谷大学奥勒姆校区开始演讲约20分钟后遭到枪击。该校在枪击事件发生后不久表示已拘留一名嫌疑人，但调查人员后来确定，被拘留者并非枪手。官员在新闻发布会上称，此人被控妨碍司法公正。
