DC shooting suspect identified, previously sued building's HOA: sources

FOX 5 sources and the Associated Press have identified the gunman in Tuesday's shooting as Matt Lambert. According to court records, Lambert filed a lawsuit in March 2025 against the homeowners association for the condo building where the shooting took place, alleging ongoing water leaks and mold contamination from 2024 facade work left him displaced from his unit and without basic appliances or HVAC.
