Police confirmed a sixth victim in a shooting that began at a VIDA Fitness gym in Washington, DC's Logan Circle on 12 November 2026, leaving building manager James Stuart dead and five wounded. Police say the suspect, 55-year-old doctor Matt Wade Lambert, targeted Stuart in a dispute over condo maintenance, then barricaded in his apartment, fired at officers, and was found dead of an apparent self-inflicted gunshot wound. Court records show Lambert had spent over $300,000 suing over mould and water problems in his penthouse since 2024.
