据执法消息人士和法庭文件显示，周六白宫外枪击事件的嫌疑人去年曾试图进入白宫区域后被捕，且他可能存在心理健康问题。
消息人士确认，这名21岁的涉案枪手是来自马里兰州邓多克的纳西尔·贝斯特（Nasire Best）。哥伦比亚广播公司新闻获取的文件显示，贝斯特曾在2025年6月封堵白宫一处入口通道，并告诉特工他是耶稣基督，希望被逮捕。贝斯特随后被送往接受精神评估，并于2025年7月再次试图进入白宫区域。
贝斯特随后被特勤局特工逮捕，并被控非法进入华盛顿联邦管控场所。据法庭文件显示，法官下令他远离该区域。
哥伦比亚特区高等法院的记录显示，贝斯特在就非法侵入指控进行传讯后获释，但他未出席2025年8月7日的庭审听证会，因此法院签发了仅适用于华盛顿特区的无保释逮捕令，授权执法人员将其逮捕。
执法消息人士告诉哥伦比亚广播公司新闻，贝斯特于周六再次出现在白宫附近的西北区第17街和宾夕法尼亚大道，从信使包中掏出左轮手枪，向美国特勤局检查站开枪。

执法消息人士称，多名身着制服的分局警员——包括至少一名驻守在白宫安全检查站外警车内的警员——还击并击毙了枪手。
一名旁观者在枪击事件中受伤，但目前尚不清楚子弹是来自嫌疑人还是赶来的警员。据执法消息人士透露，伤者已于周六晚间成功接受手术，目前情况危急但稳定。
执法官员表示，枪击事件发生在西北区宾夕法尼亚大道上的一家星巴克附近。周日可见白宫历史商店的玻璃被打碎，墙上留有弹孔。
大都会警察局将牵头开展使用武力调查，这是哥伦比亚特区特勤局人员开火后的标准流程。这意味着大都会警察局内部事务局武力调查小组的侦探将负责处理这起警员涉枪枪击案的调查工作，包括勘查现场、收集弹道和视频证据、询问证人和涉案人员，以及确定枪击和受伤的先后顺序。

华盛顿特区美国检察官办公室也会审查所有警方涉枪致死案件，以确定证据是否支持提起联邦民权或哥伦比亚特区刑事指控。
此次调查与特勤局该局职业责任办公室牵头的内部审查，以及针对嫌疑人涉嫌行为的刑事调查相互独立。

Alleged gunman outside White House had previous run-ins with Secret Service, court documents show
May 24, 2026 / 5:50 PM EDT / CBS News
The suspect in Saturday’s shooting outside the White House was arrested last year after trying to gain access to the White House, and he may have had mental health issues, according to law enforcement sources and court documents.
Sources identified the 21-year-old alleged gunman as Nasire Best of Dundalk, Maryland, and documents obtained by CBS News show Best previously blocked a White House entry lane in June 2025, telling agents he was Jesus Christ and wanted to be arrested. Best was sent for a mental evaluation and again tried to access the White House area in July 2025.
Best was then arrested by Secret Service agents and charged with unlawfully entering a federally controlled property in Washington. He was ordered by a judge to stay away, according to court documents.
D.C. Superior Court records show Best was released after an arraignment on the unlawful entry charge, but he failed to appear for an Aug. 7, 2025, status hearing, prompting a no-bond, D.C.-only bench warrant that authorizes law enforcement to arrest him.
Best reappeared outside the White House near 17th Street and Pennsylvania Avenue NW on Saturday, pulling a revolver from a messenger bag and began firing at a U.S. Secret Service checkpoint, law enforcement sources told CBS News.

Multiple uniformed division officers, including at least one stationed in a cruiser outside the White House security checkpoint, returned fire and killed the gunman, law enforcement sources said.
A bystander was wounded in the shooting, but it was unclear whether the gunfire came from the suspect or from responding officers. The victim had a successful surgery Saturday night and remains in serious but stable condition, according to law enforcement sources.
Law enforcement officials said the shooting took place near the Starbucks that is located on Pennsylvania Avenue NW. Broken glass and bullet holes can be seen on Sunday at the White House History Shop.
The Metropolitan Police Department will lead the use-of-force investigation, the standard process in D.C. when Secret Service personnel open fire. That means detectives with MPD’s Internal Affairs Bureau Force Investigation Team are expected to handle the officer-involved-shooting inquiry, including processing the scene, collecting ballistic and video evidence, interviewing witnesses and involved personnel and determining the sequence of gunfire and injuries.

The U.S. Attorney’s Office for D.C. also reviews all police-involved fatalities to determine whether evidence supports federal civil-rights or D.C. criminal charges.
The investigation is separate from the internal Secret Service review led by the agency’s Office of Professional Responsibility and from the criminal investigation into the suspect’s alleged conduct.
