One person has died and four others were injured following a shooting in Northwest Washington DC on Thursday morning, local police confirmed. Law enforcement identified the suspect as 55-year-old Matt Wade Lambert, who later died from a self-inflicted gunshot wound.
The victim was named as 46-year-old James Stuart, the building manager for the Vida Fitness gym located in Lambert’s building. Law enforcement stated that Lambert allegedly fired his handgun inside the gym before continuing to fire from his apartment patio.
Two men and two women were among those injured and were transported to hospital. One individual is in critical condition, while the others sustained non-life-threatening injuries. Police said the shooter had a "conflict between him and the homeowners association of that building." Court records indicate Lambert had been involved in a civil dispute with the association since March 2025.
Interim police chief Jeffery Carroll stated that officers were dispatched just before 8am ET to the 1500 block of 15th Street. After an hour of negotiations, officers forced entry into Lambert's apartment following another gunshot, finding him with a self-inflicted wound. Lambert was also found to have broken a gas line and started a fire in the apartment.
