Building manager shot dead by doctor in condo mold dispute

James Stewart, 46, the property manager of the Metropol Condominium Association, was killed in a shooting on Wednesday afternoon at the Vida Fitness gym located in the Logan Circle area of Washington DC. According to a report by Hindustan Times, the shooting was carried out by Dr. Matt Lambert. Five other people were also injured during the incident.

Matt Wed Lambert, 55, a doctor, is under investigation by the Washington Metropolitan Police Department (MPD). According to ABC News and other sources, Lambert had a handgun when he entered the gym, which he used to attack Stewart. Stewart was pronounced dead at the scene. No one other than Stewart died in the attack, but five people were injured.

According to Interim Chief Jeff Carroll, the primary motive behind the attack may be a long-standing dispute with the condominium association. In March 2025, Lambert had initiated legal proceedings against the building's home-owners association, the Metropol Condominium Association. The case alleged that problems with mold and water leakage had arisen in the apartment following repairs in the building. The MPD is investigating this legal dispute as a potential motive for the shooting.

Lambert had also posted about his legal case and issues related to the condo on the social media platform X. In a screenshot of a legal document shared by Lambert, James Stewart was listed as a defendant. According to a report by City Cast DC, Stewart had also appeared as a witness in court for this case. He testified regarding Dr. Lambert's reports on water ingress and mold, the management company's response, and communications with the board and engineers concerning inspections and insurance matters.

Ward 2 Council Member Brooke Pinto stated that Stewart was Lambert's sole target. Providing information about the injuries to the other four individuals, Chief Carroll stated that on Wednesday morning, Lambert was firing from the patio (balcony) of his seventh-floor condo, which resulted in four other people being injured. In this manner, a total of five people were injured.

During the police investigation, three weapons were recovered from Lambert's apartment: a handgun, a rifle, and a shotgun. Police believe that the handgun used for the attack in the gym is one of these. Chief Carroll stated that it is not yet clear how these weapons were purchased, and the investigation is ongoing. Furthermore, none of these three weapons are registered in Washington DC.

Following the entire incident, the police are focusing on various aspects of the investigation, including the legal dispute and the acquisition of the weapons. Proceedings against Lambert are currently underway, and police are gathering further details in this matter.

James Stewart served as the property manager of the Metropol Condominium Association in the Logan Circle area. He managed the maintenance and administrative affairs of the building.
