Police say DC gunman killed manager and wounded five

Washington police say Matt Lambert killed condominium manager James Stuart, wounded five other people and died by suicide during a shooting at a Logan Circle building on Thursday. The attack began inside a gym in the building, where police say Lambert shot Stuart, then continued from Lambert’s condominium unit above it.

Interim Police Chief Jeffery Carroll said Friday that the sixth victim was a woman grazed by a bullet inside the gym. She was treated at the scene and released. Police said five other people were wounded, including one who remained in critical but stable condition; three others had been briefly hospitalized with minor injuries.

Police said Lambert, 55, later barricaded himself in his seventh-floor unit. After negotiations, officers entered and found him dead from a self-inflicted gunshot wound. Carroll said investigators found several hundred rounds of ammunition and an accelerant used to start a fire in the unit. Police said the fire was stopped by the building’s sprinkler system.

Carroll said Lambert had an ongoing dispute with the condominium association over maintenance, mold and water damage, and that investigators believed the shooting was related to it....
