The Guardian reports on a fatal shooting at a Vida Fitness gym in Washington DC that left building manager James Stuart dead and four others injured. Police identified the suspect as 55-year-old Matt Wade Lambert, who had been in litigation with his building's homeowners association since March 2025 over mold and water damage, and who died from a self-inflicted gunshot wound after barricading himself in his apartment and starting a fire; officials including mayor Muriel Bowser condemned the attack, and the gym's Logan Circle location is closed until further notice.
