Gunman Kills 1, Wounds 4 at D.C. Gym a Mile From the White House, Then Dies After Standoff

A gunman shot five people in and around a gym in Washington, D.C.'s Logan Circle neighborhood on Thursday morning, killing one, before he was found dead of a self-inflicted gunshot wound in his apartment above the gym, police said. The scene is about a mile from the White House.

Early posts on social media described a shooting "near the White House" with the attacker still at large. By late morning police said the threat was over: the suspect was dead and a shelter-in-place order for the area had been lifted.

What happened

Police received the first call just before 8 a.m. local time on Nov. 12 and said officers reached the VIDA Fitness gym within about 30 seconds. They found one person dead at the scene and four others with gunshot wounds, who were taken to hospitals. Some of the victims were hurt at a construction site across the street, according to CBS News and NBC Washington.

One of the wounded is in critical condition and three have injuries that are not considered life-threatening, police said. The victims have not been publicly identified.

The gunman, who police believe used a handgun, went back to an apartment unit believed to be his in the building above the gym and barricaded himself inside. Negotiators spoke with him for about an hour, police said. After officers heard a gunshot, they forced their way in and found him with a self-inflicted gunshot wound. Police said three guns were found in the apartment.

The barricade ended and the scene was declared safe at about 11:10 a.m. The gym's Logan Circle location is temporarily closed.

What is known about the motive

Police have not released an official motive. They said the suspect had a conflict with the building's homeowners association. D.C. Council member Brooke Pinto said the shooter was targeting a person in the gym "that he had been in active litigation with over a condo issue." Fox 5 DC reported, citing an official, that a building manager was targeted.

Police have not publicly named the suspect. NBC News, citing two federal law enforcement officials, identified him as Dr. Matt Lambert.
