A shooting at a Washington, D.C., gym on Thursday morning left one person dead and four others injured, authorities said. The suspect, later identified as Dr. Matt Lambert, died from a self-inflicted gunshot wound after barricading himself in a nearby apartment and engaging in a standoff with police.
Police confirmed Lambert’s identity as the gunman involved in the attack at VIDA Fitness in the Logan Circle neighborhood. The Metropolitan Police Department (MPD) reported that the initial shooting inside the gym appeared targeted, though subsequent gunfire outside the facility did not.
Lambert, who was a member of the gym, opened fire around 8 a.m. before retreating to his apartment in the same building. Authorities recovered three firearms from his residence, according to law enforcement sources. Negotiators spoke with Lambert before he died by suicide.
Ongoing Litigation and Building Dispute
Investigators stated that Lambert had been involved in an active legal dispute with the Metropole Condominium Association over alleged mold and water damage in his unit. Court documents show he had purchased his condo in September 2016 for $1,095,000 and owned a penthouse in the building.
Lambert had filed a lawsuit against the condominium association, alleging that renovations caused water intrusion and mold. He shared what he described as an engineering report on social media, writing: “My manifesto is an engineering report.” The report, attributed to CED Technologies, appeared to support his claims of building deficiencies.
Social Media Posts and Warnings
In the days leading up to the shooting, Lambert used an X account, @OfMiceandMold, to document his grievances. He accused the homeowners association (HOA) of employing “delay, deny, defend” tactics, referencing a phrase associated with a 2024 fatal shooting. On April 28, he posted: “If you're looking for the building manager, I would check the gym.”
The account contained numerous posts, photos, and videos depicting alleged issues in his unit, including lack of hot water, HVAC failures, and dryer malfunctions persisting for months. Lambert claimed the building’s management had failed to address these problems despite his complaints.
Official Response and Investigation
Interim MPD Chief Jeffrey Carroll confirmed that Lambert had been in active litigation over condo issues. Ward 2 Council Member Brooke Pinto described the dispute as a civil matter that escalated tragically. “It's just so sad and so senseless to kill someone over a dispute that should be worked out reasonably,” she stated.
The MPD continues to investigate the shooting, including Lambert’s motives and the timeline of events. Authorities have not publicly detailed the relationship between the gym shooting and the condominium dispute beyond confirming Lambert’s prior conflicts with the building’s management.
Victims and Aftermath
One victim was pronounced dead at the scene, while three others suffered non-life-threatening injuries. A fourth victim remained in critical condition as of the latest update. The gym, located in a luxury residential tower, was evacuated during the incident, with 30 people sheltered in the basement as gunfire erupted.
The building, known as Metropole Condominiums, is situated near Logan Circle. Lambert’s unit, built in 2008, was valued at just over $1 million at the time of purchase.
Broader Context of HOA Disputes
The case has drawn attention to the potential for civil disputes to escalate into violent incidents, particularly in high-stakes living environments like condominiums. While rare, conflicts between residents and HOAs have occasionally resulted in legal action, though violent outcomes remain uncommon.
Authorities have not indicated whether Lambert’s actions were premeditated beyond the immediate context of his dispute. The investigation is ongoing, with federal law enforcement officials assisting in the probe.
