Doctor Identified as Suspect in Deadly Washington Gym Shooting
Police in Washington DC have identified 55-year-old doctor Matt Lambert as the gunman who killed condominium manager James Stuart, 46, and wounded at least four other people on Thursday in and around a Logan Circle building, not far from the White House. Officers said Lambert fatally shot Stuart inside a gym in the complex just before 8am ET, then returned to his apartment and fired from his balcony at four people, who were taken to hospital; as of Thursday, one was in critical condition. Lambert later barricaded himself in his unit and was found dead of a self-inflicted gunshot wound.
Building manager Charelle Ferguson told the Washington Post she reached Lambert by phone around 9am while checking on residents. He said he was tired of mold and water damage in his apartment, told her that “the only way people will pay attention, you have to do something,” and confessed to shooting the five people. Ferguson said she had previously heard his complaints and been sympathetic, and that she never thought he would act this way.
Court records show Lambert sued his condo association in 2025, alleging it failed to fix water damage, mold and moisture that began after exterior work on the building. The association denied negligence and responsibility; the case was still ongoing. His civil attorney, Joel Braithwaite, said he last spoke with Lambert on Tuesday and that he had sounded fine, adding that he was deeply shocked because the client he knew was “in the business of healing people.” On Thursday evening, residents held a vigil in the neighborhood.
