A shooting in Washington DC on Thursday morning left one person dead and four injured. Police identified the deceased victim as James Stuart, 46, of northwest Washington DC. The suspect, 55-year-old Matt Wade Lambert, also of northwest Washington DC, died from a self-inflicted gunshot wound.
Two men and two women were injured in the incident, with one victim in critical condition and the others sustaining non-life-threatening injuries. Police said the victim killed inside the gym was the building manager for that location.
Authorities believe the shooting was connected to the suspect's ongoing disputes with the building's management regarding maintenance issues. Police stated that the suspect broke a gas line inside his apartment fireplace and started a fire, with visible flames and flammable materials found inside his apartment.
Three firearms – a shotgun, a rifle, and a handgun – were located inside the suspect's apartment and were all used by the suspect. VIDA Fitness, the gym where the shooting occurred, remains closed until further notice.
