One Dead in DC Gym Shooting: Police Identify Suspect

A 55-year-old emergency room doctor shot and killed a condominium building manager inside a Washington D.C. gym before shooting himself after a standoff, according to CNBC Indonesia.

Matt Wade Lambert opened fire inside VIDA Fitness on November 12, killing 46-year-old James Stuart, who managed the property where the suspect lived. Four other people sustained injuries during the attack in the Logan Circle neighborhood, located near the White House.

“Orang-orang hanya bersembunyi di balik pot tanaman dan furnitur,” said VIDA Fitness member Michael Carney.

Police and court records show Lambert had been fighting the condominium association over water leaks and mold in his penthouse unit. Court documents indicate he claimed the damage made his home uninhabitable and spent around $300,000 on repairs. The association disputed the claims and filed a cross-complaint against the ground-floor gym’s commercial dryers.

“There has been a longstanding dispute between the tersangka in this case and the management regarding building maintenance, mold, and similar issues,” said Jeff Carroll, Acting Chief of the Metropolitan Police Department, as reported by Liputan6.com. “We suspect this shooting is related to that dispute.”

Joel Braithwaite, Lambert’s lawyer, described the apartment’s condition as a war zone due to the unresolved maintenance issues. Braithwaite told reporters he was completely devastated and shocked by the violence.

Following the initial shooting in the gym, Lambert went to his seventh-floor apartment and used a rifle to fire down from his balcony at people on the ground floor. “Dia memiliki teras balkon di sana dan kami yakin dia menembak dari lokasi itu, mengenai empat orang lainnya yang menjadi korban dalam kasus ini. Mereka berada di lantai dasar,” said Jeff Carroll of the Metropolitan Police Department Jeff Carroll.

Emergency responders evacuated four injured victims—two women and two men—to local hospitals. One of the wounded individuals remained in critical condition by Thursday afternoon, while tactical SWAT teams secured nearby rooftops and streets.

Negotiators attempted to end the standoff before officers breached the apartment and found Lambert dead from a self-inflicted gunshot wound. The incident shut down the 1500 block of 15th Street as law enforcement cleared the scene.

The shooting took place on November 12, 2026, in Washington D.C.
