DC Gym Shooting Victim Count Rises To 6; Police Reveal New Details

WASHINGTON, DC — A sixth victim has been identified in Thursday's deadly shooting in Washington, D.C.'s Logan Circle neighborhood, bringing the total to one person killed and five wounded, police announced Friday.

The newly identified victim, an adult woman, suffered a non-life-threatening graze wound and treated herself, according to an updated Metropolitan Police Department news release.

Police initially reported five shooting victims, including 46-year-old James Stuart, a manager at the Metropole condominium building who was killed inside VIDA Fitness in the 1500 block of 15th Street NW.

The four other victims initially identified — two men and two women — were hospitalized. One was in critical condition Thursday afternoon.

Police also confirmed Friday that three firearms recovered from the gunman's apartment — a shotgun, rifle and handgun — were all used in the shooting. None was registered to the suspect in the District of Columbia.

The gunman, identified as Matt Wade Lambert, 55, fatally shot himself inside his seventh-floor condominium following a standoff with police.

Gunman Had Longstanding Dispute With Condo Management

Investigators believe the shootings were connected to Lambert's ongoing dispute with management of the Metropole condominium building over mold, moisture and water damage in his penthouse.

Lambert, a doctor who later worked as a medical consultant, filed a lawsuit against the condominium association and property management company in 2025, alleging they failed to address persistent problems in his unit.

He claimed exterior construction work in 2024 allowed water to enter the apartment and sought at least $300,000 in damages.

According to court records reviewed by The Washington Post, Lambert alleged that Stuart dismissed his concerns during an inspection, describing the mold odor as smelling like cologne.

The condominium association and EJF Real Estate Services denied responsibility for the damage. The association subsequently suggested that an exhaust system associated with VIDA Fitness might have contributed to the problem, an allegation the gym's owners disputed.

The lawsuit remained unresolved when the shooting occurred.

Social Media Posts Mentioned Victim's Gym Routine

New reporting also revealed that Lambert apparently discussed Stuart's gym habits in social media posts months before the shooting.

An X account believed to belong to Lambert, called OfMiceandMold, contained dozens of complaints about conditions at the building, including mold, mice and air conditioning problems.

Posts from April and May mentioned Stuart's visits to VIDA Fitness, including one suggesting that anyone looking for the building manager should check the gym.

VIDA Fitness owner David von Storch told The Washington Post that security footage showed Lambert shooting Stuart in the back at close range.

Stuart regularly exercised at the gym around the same time each morning, von Storch said.

Building Manager Says Lambert Confessed

Charelle Ferguson, another manager at the Metropole, told The Washington Post that Lambert admitted shooting five people during a telephone conversation shortly after the attack.

Ferguson said she called Lambert around 9 a.m. Thursday while checking on residents following the gunfire.

Lambert complained about mold and water damage in his condominium and suggested that drastic action was necessary to get people's attention, she recalled.

He then told her he had shot five people, including one of her co-workers, Ferguson said.

She kept him on the phone until police approached, then handed the phone to an officer.

Shooting Lasted Less Than 5 Minutes

The violence began shortly before 8 a.m. Thursday inside VIDA Fitness near 15th and P streets NW.

Interim Police Chief Jeffery Carroll said Lambert shot Stuart inside the gym before returning to his condominium and opening fire on people below from his seventh-floor patio.

"This whole incident took place in less than five minutes," Carroll said.

Witnesses described gym members scrambling to escape after hearing gunshots and seeing Stuart collapse.

James Spellman, who was exercising at the gym, estimated about 50 people were inside when the shooting began.

Anthony Mirones, another gym member, said people rushed toward the exits after a fire alarm sounded.

Lambert later barricaded himself inside his apartment and fired through the door at responding officers.

Police negotiators spoke with him for more than an hour before hearing a gunshot. Officers forced their way inside and found him suffering from an apparent self-inflicted gunshot wound.

Carroll said Lambert also cut a natural gas line and started a fire inside the condominium. The building's sprinkler system activated and contained the flames.

The shootings prompted school lockdowns, road closures and a shelter-in-place order around Logan Circle. Those emergency restrictions were later lifted.

Investigation Continues

Police have not publicly identified the five surviving shooting victims.

The investigation remains ongoing. Anyone with information is asked to call MPD at 202-727-9099 or submit an anonymous text tip to 50411.
