A 55-year-old doctor identified as Matt Wade Lambert opened fire at a Logan Circle gym on Thursday morning, killing the building’s manager before barricading himself in a nearby apartment where he later died from a self-inflicted gunshot wound.
The violence erupted just before 8:00 a.m. inside the VIDA Fitness center located in the 1500 block of 15th Street Northwest. According to Metropolitan Police Department (MPD) Interim Chief Jeffery Carroll, the department received reports of a shooting and dispatched officers who arrived on the scene within 30 seconds. Inside the gym, the gunman fatally shot James Stuart, the 46-year-old manager of the building.
CRITICAL ALERT: MPD is on the scene of an ACTIVE SHOOTING in the area of 15th and P Street, Northwest. MPD’s Emergency Response Team is on scene. AVOID THE AREA.
Witnesses described the sudden panic as approximately 50 people were inside the facility at the time. James Spellman, a gym member, recounted that within seconds of the shots, a man fell to the ground, and one member attempted to provide aid to the victim, who had been shot in the neck.
The Dispute at Metropole Condos
Authorities, including Chief Carroll, confirmed that the incident stemmed from an ongoing dispute between the suspect and the building’s homeowners association regarding maintenance issues, specifically citing moisture, water intrusion, and mold. Lambert, a board-certified emergency physician, had purchased his unit for $1,095,000 in 2016. Court records indicate that Lambert was engaged in active litigation against the building management, with mediation previously scheduled for next March.
Update: The barricade has concluded. The scene is safe. Significant traffic closures remain in place. MPD is still asking the public to avoid the area.
Lambert reportedly maintained an online presence under the handle “OfMiceandMold,“where he shared engineering reports and photos of his unit. He had previously expressed feelings of being in”psychological warfare“with building management. His attorney, Joel Braithwaite, told reporters he was”deeply shaken and saddened” by the violence, noting that Lambert had invested more than $300,000 into pressing his legal claims.
Chaos in Logan Circle
The shooting triggered a response involving law enforcement. As the situation escalated, residents were issued emergency text alerts ordering them to shelter in place, an order that remained in effect until approximately 11:30 a.m. Anthony Mirones, who was on a treadmill during the attack, described the initial sounds as a loud bang that made the floor shake, followed by the sight of a body on the floor with blood nearby.

Gym members scrambled to escape, with many forced to step over the victim to exit the building.
Nearby businesses, including the Call Your Mother deli, became temporary sanctuaries for those fleeing the area. Oscar Vazquez, the deli manager, reported hearing fire alarms from the apartment building followed by aggressive gunfire.

Outside, workers like John Brooks, who was opening a nearby business, witnessed crowds running in terror, describing a scene where it felt as if “every police officer in the city” had arrived. During the incident, four additional people were wounded by gunfire, including a construction worker who was grazed in the arm while near the building.
Lambert Barricaded Himself and Fired at Officers
After the initial shooting, Lambert retreated to his seventh-floor unit, where he barricaded himself and fired at officers through the door. Law enforcement discovered evidence that the suspect had ripped out drywall and utilized gasoline inside the apartment.
The shooting in Logan Circle this morning is horrifying. A life was lost in this unthinkable tragedy and I’m sending my sincere condolences to all the victims, their families, and DC residents living through this fear.
During a standoff, hostage negotiators attempted to communicate with Lambert, who reportedly launched into a tirade about his homeowners association. Chief Carroll said that while negotiators were speaking with the suspect, they heard a single gunshot, at which point communication ceased. Police later found a shotgun, a handgun, and a rifle inside the apartment.
While local officials and witnesses said that the Logan Circle neighborhood is generally considered safe, the event left a profound impact on the community. Authorities continue to investigate the sequence of events, and Metro Transit Police have increased their presence at nearby stations to ensure public safety.
