Police continue to negotiate with the active shooter suspect, who is barricaded inside of an apartment at 1517 15th Street NW, over the phone. It appears a fire has been intentionally set inside that same area. DC Fire & EMS not able to gain access inside. https://t.co/deG6Nx8tAu

The shooter was identified as Dr. Matt Lambert, and his motive apparently stemmed from black mold reportedly building up in his residence; he blamed Vida’s washers and dryers for contributing to the condensation in his penthouse. The attack occurred near Logan Circle. The person who was killed was the building manager (via City Cast DC):

The suspect who unleashed gunfire in a popular Logan Circle gym Thursday morning, killing one person and wounding four others, was Matt Lambert, a federal law enforcement official confirmed to City Cast DC.
NBC Washington also identified the suspect as Lambert, citing two federal law enforcement officials. Lambert is a board-certified emergency physician, according to his website.
Court records show Lambert, a resident of Metropole Condos, had an active lawsuit against the condo association, alleging that work on the building’s facade caused water to leak into his penthouse unit resulting in more than $100,000 in damages.
Lambert also appears to be connected with an X account that complained about mold in the Metropole building and how his unit — an “uninhabitable penthouse” — wasn’t getting repaired like the others in the building.
At 8:06 a.m. Thursday, the account posted screenshots of what it called a “manifesto,” an engineering report showing how water damage and lack of care in the building had led to mold and disrepair.
Some of the posts appear to be screenshots from emails with VIDA Fitness, which is below Metropole Condos. In the lawsuit, the condo association claimed that VIDA’s laundry dryers caused excess moisture buildup in his unit. The account also posted about the issue in June.
Lambert opened fire at officers as he barricaded himself inside.
There’s also a paper trail: he filed a lawsuit in D.C. Superior Court in 2025, alleging that black mold was found during façade repairs. He claimed he had been unable to live in the residence since November 2024 because of the infestation.
