Gunman dead after killing one and wounding four at a DC gym near Logan Circle, police say

One person has died and at least four others were shot Thursday morning at and outside a Vida Fitness gym near Logan Circle in Northwest Washington, D.C., about a mile from the White House, WUSA9 reports.

The shooter is barricaded inside a building on the 1500 block of 15th Street NW. Police told Fox News Digital they no longer consider him at large and that he is "contained" by officers. D.C. police's Emergency Response Team is on scene, and the ATF is assisting.

Police have urged people near 15th and P Streets to shelter in place and stay indoors. Nearby schools were locked down, and several roads and bus routes around the area are closed.

The shooting began shortly after 8 a.m. ET. D.C. Councilmember Brooke Pinto said the shootings happened "at and outside" the gym. The victims have not been identified, and police have not released a motive. This is a developing story.

Update, Nov. 12, 11:40 a.m. ET: The gunman is dead. D.C. police interim Chief Jeffery Carroll told reporters that while officers were communicating with the barricaded suspect, they heard a gunshot inside the apartment, broke down the door and found him with a self-inflicted gunshot wound. Two law enforcement officers briefed on the situation told Fox News he has died, and D.C. Councilmember Brooke Pinto also said the suspect is dead, FOX 5 DC reported.

Carroll said the suspect, a white man, also fired at officers from inside the apartment building. One of the four wounded victims is in critical condition. The shooting was first reported around 8 a.m. inside the Vida Fitness gym near 15th and P Streets. Police are still working to establish a motive, but Carroll said they had documented a conflict between the suspect and the homeowners association of the building where he barricaded himself.

"We're devastated. Someone was killed in our city this morning in a senseless act of gun violence," Mayor Muriel Bowser said. "This lone gunman has been contained."

Update, Nov. 12, 12:55 p.m. ET: The gunman targeted and killed the manager of his apartment building, someone he had recently been in litigation with, D.C. Councilmember Brooke Pinto said, FOX 5 DC reports. (Pinto first described the victim as the building's owner; FOX 5 DC later said it was the manager.) Pinto said the suspect then left Vida Fitness and shot others outside, including several construction workers and a woman, possibly at random as he tried to flee, before going back into the building and barricading himself. She said he set parts of the building on fire before he shot himself.

Update, Nov. 12, 2:15 p.m. ET: Officials identified the gunman as Dr. Matt Lambert, a doctor who lived in a penthouse in the building above the gym on 15th Street NW, according to the Associated Press. Lambert filed a lawsuit in 2025 saying he had not been able to use his penthouse since 2024 because of mold, moisture and water problems. Police say he shot himself in the apartment while on the phone with police negotiators. D.C. police have not formally released his name.

Update, Nov. 12, 3:35 p.m. ET: Shortly before the shooting, an X account linked to Lambert posted "My manifesto is an engineering report" around 8 a.m. Thursday, attaching a report that cites "suspected microbial growth," water intrusion and a large bill to repair the wall of his penthouse, the New York Post reports. The account had posted dozens of times in recent months about leaks, mold and rodents in the building.
