Man shot dead in Washington DC gym is named

A man shot dead in a Washington DC gym on Thursday has been named.

Building manager James Stuart, 46, from northwest Washington DC, was killed just before 8am on Thursday, Metropolitan Police Department interim Chief Jeffery Carroll told reporters.

The gunman - identified as Matt Lambert, a doctor - wounded four others at the VIDA Fitness gym before barricading himself in his apartment and turning the gun on himself, law enforcement officials have said.

Chief Carroll said: "We do know that there has been an ongoing dispute between the suspect in this case and the homeowners association management regarding maintenance issues, mould and the like.

"There was a civil case that he filed against them. So we believe that it's related to that."

One of the wounded is in a critical condition, Chief Carroll added. The three others have non-life-threatening injuries.

Sky has learnt that Lambert had owned and lived in the apartment, which has an estimated value of more than $1m (£755,000), since 2016.

An account on X, believed to be Lambert's, posted 200 times about issues with his apartment building over a 13-month period. A "manifesto" was posted by the account shortly after the shooting.

James Spellman, who was at the gym, said there were about 50 people inside when the shooting began.

"Within seconds there was a man who fell to the ground, and a pool of blood came out," he said. "One gym member rushed to help him. He was instantly dead. He had been shot in the neck."

Officers had arrived on the scene within seconds of the initial call, Chief Carroll said.

While clearing a nearby residential building, police heard gunfire coming from ​the seventh floor, where the suspect had holed himself up in his ⁠own apartment.

Negotiators heard a gunshot while talking to him on the phone during a standoff.

"He did fire through the door at officers, at least on two occasions, while he was barricaded inside," Chief Carroll told a news conference.

When officers forced their way into the flat, the suspect was found dead from a self-inflicted gunshot wound.

Washington ⁠Mayor Muriel Bowser praised the swift law enforcement response ​to what she described as a "senseless act of gun violence", adding that the ​White House had been briefed.
