FBI介入调查多名科学家神秘死亡，国会议员致信NASA要求彻查
联邦调查局（FBI）正对近期一系列美国科学家的神秘死亡事件展开调查，引发国会关注。据10月2日报道，国会众议员已致信包括NASA在内的多个联邦机构，要求说明这些事件是否涉及针对美国科研人员的国家安全威胁。特朗普总统听取简报后称情况"相当严重"（pretty serious stuff），预计几周内会有答案。
报道指出的关键案例包括四名洛杉矶地区科学家，其中三人与位于拉肯纳达弗林特里奇（La Cañada Flintridge）的NASA喷气推进实验室（JPL）有关：加州理工学院天体物理学家卡尔·格里尔梅尔（Carl Grillmair）遭枪击身亡，嫌疑人已被控谋杀；退休空军少将威廉·"尼尔"·麦卡斯兰（William "Neil" McCasland）2026年自新墨西哥州家中失踪，调查人员暂未发现谋杀迹象；NASA工程师约书亚·勒布朗（Joshua LeBlanc）死于一辆烧毁的汽车内。这些事件横跨2022年至2026年，涉及JPL和洛斯阿拉莫斯等实验室。
NASA表示正全力配合调查，但未发现当前存在国家安全威胁；FBI则强调正在评估所有可能性，在没有初步证据显示案件有关联的情况下，不排除谋杀可能。
FBI Probes Mysterious Deaths of Scientists; Lawmakers Press NASA for Answers
The FBI is investigating a series of mysterious deaths of U.S. scientists, drawing congressional attention. According to October 2 reports, House members have written to multiple federal agencies including NASA, asking whether the incidents point to a national security threat against American researchers. President Trump, after a briefing, called the situation "pretty serious stuff" and said answers are expected within weeks.
Key cases cited include four Los Angeles-area scientists, three of them tied to NASA's Jet Propulsion Laboratory (JPL) in La Cañada Flintridge: Caltech astrophysicist Carl Grillmair was shot dead and a suspect has been charged with murder; retired Air Force Maj. Gen. William "Neil" McCasland vanished from his New Mexico home in 2026 with no sign of foul play found so far; NASA engineer Joshua LeBlanc died inside a burned-out car. The cases span 2022 to 2026 and involve JPL and Los Alamos laboratories.
NASA says it is fully cooperating but has found no current national security threat; the FBI stresses it is evaluating all possibilities and is not ruling out homicide even without preliminary evidence linking the cases.
