DC Gym Shooter Identified as Doctor in HOA Dispute

Dr. Matt Lambert, a local physician, fired a gun inside the VIDA fitness center in Washington, D.C., on Thursday morning. The attack killed one person and wounded four others. Lambert was also killed in the incident. Law enforcement officials and one person familiar with the matter identified the doctor to The Associated Press on condition of anonymity.

Authorities stated that the shooting began around 8 a.m. in the Logan Circle neighborhood. Dispatch audio from the scene indicated that approximately 30 people took cover in the gym's basement while the gunfire erupted. The event ended with the death of the shooter and the victim.

Lambert had been involved in a conflict with his homeowner's association for some time. He filed a lawsuit against the management company of his apartment building last year. The dispute centered on building maintenance, specifically allegations of mold and water intrusion. These issues were detailed in an independent engineering report that Lambert cited in his online posts.

In the minutes before the shooting, an X account named "OfMiceandMold" shared updates on the conflict. Less than 10 minutes before the first calls regarding the gunfire arrived, the account posted the message, "My manifesto is an engineering report." The post included screenshots of the document outlining the problems with the Metropole Condominium Association. The account also contained earlier posts from early October referencing "months of 'Luigi' tactics" and the submission of the engineering report.

The shooting remains under investigation. Officials described the conflict as an apparent dispute but have not confirmed a direct causal link between the HOA lawsuit and the attack. The gym in the District's Logan Circle neighborhood was the site of the violence.
