The gunman responsible for a deadly shooting at a Washington, D.C. gym Thursday morning has been identified as an emergency room doctor embroiled in a bitter legal dispute over mold and water damage in his $1.1 million condominium, according to multiple reports.

Dr. Matt Lambert, 55, opened fire at the VIDA Fitness center in Logan Circle shortly before 8 a.m., killing one person and wounding four others before barricading himself inside his seventh-floor unit at the nearby Metropole condominium. After an hour-long standoff with police, officers found Lambert dead from an apparent self-inflicted gunshot wound.

Targeted Attack Over Condo Dispute
D.C. Councilmember Brooke Pinto told reporters the shooting appeared targeted, with Lambert allegedly seeking someone involved in his ongoing litigation against the Metropole Condominium Association. “We believe the suspect walked into Vida to target somebody that he had been in active litigation with, over a condo issue,” Pinto said.

Court records show Lambert filed a seven-figure lawsuit in March 2025 alleging the building’s repairs caused severe water intrusion, mold growth, and living conditions that left him without basic amenities for months. “Two years of living in luxury (and the start of 6 months with no shower, dryer, HVAC, and cooking),” Lambert posted on social media just one day before the attack, according to local outlet City Cast DC.
Medical Career to Murder Suspect
The violent incident stands in stark contrast to Lambert’s professional background as a board-certified emergency physician with over 20 years of experience. His personal website described him as a published author, musician, and philanthropist who split time between D.C. and West Virginia.
The shooting triggered a massive police response in the upscale neighborhood just north of the White House, with helicopters circling overhead and nearby schools placed on lockdown. One resident described the scene to The Daily Wire as feeling “like a war zone.”
D.C. Mayor Muriel Bowser condemned the “senseless act of gun violence” while confirming the White House had been briefed. Of the four wounded victims, one remains in critical condition while the others sustained non-life-threatening injuries.
