Police Name Matt Lambert as Gunman in Fatal Washington DC Condo Shooting

A shooting on Thursday morning in northwest Washington, DC, killed one person and injured at least four others. Police identified the gunman as Matt Lambert, 55, a doctor who had been involved in a legal dispute with the management of his building.

The shooting took place in and around a condominium building in the Logan Circle neighborhood, near the White House. The person killed was James Stuart, 46, a manager at the condominium complex. According to The Guardian, Lambert shot Stuart inside a gym in the building just before 8am Eastern time.

Lambert then fired at four people from his apartment balcony. Those four were taken to hospital, and one was in critical condition as of Thursday. Lambert barricaded himself inside his unit, meaning he locked himself in and stayed there, and was found dead with a self-inflicted gunshot wound.

Charelle Ferguson, the building manager, spoke with Lambert by phone at around 9am that morning. The Guardian reported that Lambert told her he was tired of mold and water damage in his apartment, and that he confessed to her over the phone to shooting five people.

Lambert had sued his condo association in 2025, alleging it had failed to address water damage, mold and moisture problems in his apartment. He alleged the damage began after exterior work was carried out on the building. The association denied negligence and responsibility for the damage, and the case remained ongoing.

Joel Braithwaite, Lambert's attorney in that civil case, said he last spoke with Lambert on Tuesday and that Lambert sounded fine.
