The gunman who killed one person and injured four others in Washington, D.C.’s Logan Circle neighborhood Thursday morning has been identified in media reports as an emergency room doctor embroiled in a legal battle over mold and water damage in his condominium.

Dr. Matt Lambert, 55, had sued the Metropole Condominium Association over conditions in his $1.1 million residence, according to the New York Post. He was later found dead from a self-inflicted gunshot wound after barricading himself inside his home. 

The shooting began at the ground-floor VIDA Fitness shortly before 8 a.m. ET. Officers arrived within 30 seconds. One victim died, and four others were rushed to the hospital, with one listed in critical condition and the others suffering non-life-threatening injuries, The Daily Wire reported. 

Authorities said the gunman had an ongoing “conflict” with the building’s homeowners association. D.C. Councilmember Brooke Pinto suggested the attack was targeted.

“We believe the suspect walked into Vida to target somebody that he had been in active litigation with, over a condo issue,” Pinto said.

After the shootings, Lambert barricaded himself inside his seventh-floor condo and fired at police. Authorities communicated with him for more than an hour before hearing a gunshot inside. Officers then entered and found him dead.

According to the New York Post, Lambert filed a seven-figure suit against the Metropole Condominium Association in March 2025, alleging that building repairs resulted in water intrusion, moisture accumulation, mold growth, and other damage inside his residence at 1515 15th St. NW.

An X account linked to Lambert detailed his frustrations, posting Wednesday: “Two years of living in luxury (and the start of 6 months with no shower, dryer, HVAC, and cooking).” The same account posted screenshots of an engineering report about the water damage, referring to the document as a “manifesto,” according to local outlet City Cast DC. 

A personal page belonging to Lambert described him as a “board-certified emergency physician with over two decades of clinical experience.” 

“He brings a unique blend of leadership, technology expertise, and policy acumen to his work,” the website reads. “Beyond his professional pursuits, Dr. Lambert is a published author, musician, and a dedicated philanthropist,” adding that he split his time between the nation’s capital and the West Virginia mountains. 

The shooting sparked a massive law enforcement response throughout Logan Circle, an up-and-coming residential neighborhood approximately a mile north of the White House. 

“Feels like a war zone in DuPont right now,” one resident told The Daily Wire. “Helicopters and cops everywhere. We are in an emergency shelter in place.”

Nearby schools were temporarily placed on lockdown as officers secured the surrounding area. Social media footage showed scores of law enforcement personnel rushing to the scene.

D.C. Democrat Mayor Muriel Bowser confirmed that the White House had been briefed on the shooting, calling it a “senseless act of gun violence.”
