Secret Service officials confirmed in an initial press briefing that uniformed officers were dispatched to the intersection of 7th Street and Constitution Avenue NW, a high-foot-traffic area steps from the Smithsonian National Museum of American History and popular tourist gathering spots, following multiple 911 calls reporting a man wielding a kitchen knife and screaming threats at passersby. When officers arrived on scene, the suspect ignored repeated verbal commands to drop the weapon, and allegedly lunged at two responding officers without warning, prompting at least one officer to discharge their service weapon. The suspect was struck once in the upper torso, and received immediate on-scene first aid before being transported to a local trauma center with non-life-threatening injuries. During the exchange of gunfire, a 32-year-old female tourist from Cleveland, Ohio, who was visiting the National Mall with her husband and two young children, was grazed by a stray bullet on her left forearm. She was treated on site by DC Fire and EMS personnel and released less than an hour later without requiring inpatient care, according to official EMS reports. The entire surrounding area was immediately cordoned off following the shooting, with access to three nearby Smithsonian museums restricted for approximately two hours as crime scene investigators collected shell casings and interviewed witnesses. The Secret Service Office of Professional Responsibility, DC Metropolitan Police Department and National Park Service are all collaborating on the ongoing investigation to verify whether the use of force aligned with standard department protocols, and to trace the full trajectory of all bullets fired during the incident. Secret Service leadership emphasized that no protected government officials were in the area at the time of the shooting, and there is no ongoing threat to the public or nearby federal properties. Witness accounts shared on social media described chaotic scenes as hundreds of tourists and local office workers scattered when gunshots rang out, with many taking shelter inside nearby cafes and museum lobbies until law enforcement issued an all-clear notice. The officer involved in the shooting has been placed on paid administrative leave pending the conclusion of the investigation, per standard Secret Service policy for use-of-force incidents.
