1 killed, 4 shot in DC gym shooting; police chief updates Logan Circle barricade One person is dead and four others were injured following a shooting inside a Washington, D.C., gym that led to an active barricade situation in the Logan Circle neighborhood, D.C. Police Chief Jeffrey Carroll said. During a preliminary briefing, Carroll said officers responded just before 8 a.m. to a shooting inside a gym in the 1500 block of 15th Street Northwest. Officers arrived within 30 seconds and found four people who had been shot and taken to hospitals, along with one person who died at the scene. While officers were clearing a nearby apartment building in the 1500 block of 15th Street, gunshots rang out on the seventh floor, where the suspect barricaded himself inside an apartment. Carroll said Metropolitan Police Department negotiators and the Emergency Response Team made contact with the suspect and have been speaking with him for more than an hour as local and federal agencies remain on scene. The Brief One man was killed and four other people were wounded early Thursday. D.C. Councilmember Brooke Pinto confirmed the suspect was dead. Most roads reopened by noon. WASHINGTON - One man was killed, and four other people were wounded early Thursday in a shooting that began inside a gym in Washington, D.C.'s Logan Circle neighborhood.  The suspect barricaded himself in a nearby apartment, fired at officers and died of what appeared to be a self-inflicted gunshot wound, officials said. D.C. Councilmember Brooke Pinto confirmed the suspect was dead and said the gunman targeted the building’s manager, 46-year-old James Stuart, who was fatally shot inside the gym. Police confirmed the suspect as 55-year-old Dr. Matt Lambert. RELATED: DC shooting: What we know about the suspect What we know: The shooting was reported just before 8 a.m. near 15th and P streets, D.C. Police Chief Jeffery Carroll said. Stuart was pronounced dead at the scene, and four other shooting victims, two men and two women, were taken to hospitals. One was in critical condition, while the other three suffered injuries that did not appear to be life-threatening, Carroll said. After clearing the gym building, officers began searching an apartment building in the 1500 block of 15th Street, Carroll said. While officers were clearing the building, gunfire erupted from the seventh floor, where Lambert had barricaded himself inside his condo and fired through the door at officers at least twice, Carroll said. Lambert also began shooting from the patio balcony with a rifle, hitting four victims on the ground level. Negotiators established contact with Lambert and spoke with him for more than an hour in an effort to end the standoff, Carroll said. While communicating with him, officers heard a gunshot and forced their way into the condo, where they found Lambert suffering from what appeared to be a self-inflicted gunshot wound. Emergency medical aid was rendered at the scene. D.C. Mayor Muriel Bowser said she was "devastated" and called the shootings a "senseless act of gun violence." Officers recovered three firearms at the scene: a rifle, a handgun and a shotgun. Police said Lambert was a member of the gym and had been involved in a conflict with the apartment building's homeowners association. Investigators believe the shooting was related to a lawsuit and dispute. Court documents show Lambert filed a lawsuit in March 2025 against the homeowners' association for the condo building where Thursday's shooting happened. In the lawsuit, Lambert claimed that ongoing water leaks and mold contamination stemming from facade work in 2024 had interfered with his use and enjoyment of the home. The March 2025 court filings alleged that Lambert had been displaced from his unit since November 2024 and had been unable to use his shower, HVAC, stove or dryer since October 2024. At some point, Lambert broke a gas line in his apartment and started a fire, triggering fire alarms and sprinklers and leaving significant water inside, Carroll said. The building's sprinklers helped to contain the fire. Officials said they found multiple flammable substances in Lambert's condo. Federal agencies joined local officers at the scene. The FBI Washington Field Office said it was assisting with the investigation and urged the public to avoid the area, while the Bureau of Alcohol, Tobacco, Firearms and Explosives also deployed agents to help. Authorities cordoned off much of the 1500 block of 15th Street, which includes residences, a VIDA fitness center and St. Luke's Episcopal Church, and sits around the corner from a Whole Foods supermarket. Several District of Columbia Public Schools were placed on alert status, meaning instruction continued inside while no one was allowed to enter or exit the buildings. That alert has since been lifted, and police said a shelter-in-place order for area residents has also been lifted. Residual traffic delays remained Thursday evening, though most roads reopened by noon. The Logan Circle neighborhood has experienced high-profile violence before. In early August 2025, a former member of President Donald Trump's Department of Government Efficiency was assaulted early on a Sunday morning in Logan Circle by a group of teenagers attempting to carjack him and a woman, authorities said. Trump later bypassed local authority to impose direct federal control over the city and deployed hundreds of National Guard members to reduce crime. Police said the investigation remains ongoing and asked any witnesses to contact authorities. What they're saying: Lambert's attorney, Joel Braithwaite, spoke to the press on Thursday evening, revealing that the day of the shooting was also the anniversary of Lambert burying his mother. According to Braithwaite, Lambert was set to begin a new job next Monday. Braithwaite expressed shock over the allegations and detailed the current standing of Lambert's lawsuit. "I can't tell you how surprised I am, because the person that I knew as a client was an emergency room physician, someone that was in the business of healing people. I've seen him be a humanitarian," Braithwaite said. According to Braithwaite, Lambert attended depositions last week and, in the 24 to 48 hours before the shooting, was in "great spirits." "I'm at a loss for how things took any sort of turn," Braithwaite said. When asked about Lambert's feelings toward the ongoing lawsuit, Braithwaite said, "Litigation wears on you, and it takes tolls on people…We have motions and things that are pending, but by all accounts, things were going very well for us." He also revealed that Lambert and Stuart had been using the same gym for three years during ongoing litigation. "Litigation is supposed to prevent these results, to litigate in court and not have it spill out into the streets," Braithwaite said. What we don't know: Authorities have not yet released an official motive for the shooting or confirmed whether Matt Lambert's 2025 lawsuit against the building's homeowners association was directly connected to the attack. Police have not yet identified the four wounded victims. It is unclear if Lambert had a relationship with the other victims.
