Doctor kills condo manager, wounds four, then dies in DC shooting

Matt Lambert, a 55-year-old emergency room physician, entered a ground-floor gym in a Washington condominium building shortly before 8 a.m. on Thursday and shot building manager James Stuart, 46, who died.

Lambert then barricaded himself in his seventh-floor penthouse unit and shot four more people from his patio. Three of the wounded suffered non-life-threatening injuries, while one remained in critical condition.

“I'm scared to death.”

The shooting occurred in the Logan Circle neighborhood, about a mile north of the White House. Police cordoned off much of the block on 15th Street Northwest and urged people to avoid the area.

Lambert had been locked in litigation with the condo association over mold and moisture problems in his unit. He alleged that he had been unable to enjoy his penthouse since 2024 because of water leaks following exterior work on the building.

After a standoff with police, during which he spoke by phone with negotiators, Lambert fatally shot himself. Metropolitan Police Department interim chief Jeffery Carroll said the entire incident took place in less than five minutes.

Mayor Muriel Bowser described the loss of life as devastating and called the shooting a senseless act of gun violence. Schools in the area were locked down during the police response.
