The gunman in a deadly shooting at a Washington, D.C. gym has been identified by law enforcement sources as Dr. Matt Lambert. The shooting, which occurred at the VIDA gym in the Logan Circle neighborhood, resulted in one fatality and four injuries. Lambert was also killed in the incident.
Authorities stated that the shooting began around 8 a.m. Sources familiar with the matter confirmed Lambert's identity to The Associated Press on condition of anonymity.
According to the AP report, Lambert had an ongoing dispute with the management of his apartment building and had filed a lawsuit against the company the previous year. Posts on an X account, identified as "OfMiceandMold," which law enforcement sources believe belonged to Lambert, appeared shortly before the shooting. One post stated, "My manifesto is an engineering report," accompanied by screenshots of what seemed to be an engineering document.
Photos of the dispute between Lambert and the Metropole Condominium Association highlighted issues such as mold and water intrusion. In an October post, Lambert criticized his HOA for what he described as "months of 'Luigi' tactics" and mentioned submitting an independent engineering report.
The incident remains under investigation.
