A 46-year-old building manager was shot dead in Washington DC yesterday (November 12) by a gunman following a long-running dispute over mould in his apartment.
Police have identified Matt Wade Lambert, a 55-year-old doctor, as the gunman who targeted The Metropole building, based in the Logan Circle neighbourhood of Washington DC.
The Washington Sun had spoken to Lambert a year prior to the attack, as he described how a dispute over severe water leaks and black mold had turned into 'psychological warfare' between himself, his victim James Stuart, and the management company EJF Real Estate Services.
Speaking in December 2025, he said to the outlet: "It’s affected every part of my life - my sleep, dietary habits.

"I pride myself on my resilience, and I’ve been kind of surprised at how much it has been affected."
But at no point, the publication claim, did Lambert hint at resorting to violence as a resolution.

Speaking to a fellow resident who was also waiting for repairs, he allegedly said: "If you want to see the building manager he comes in the gym about 8 o’clock."
Following the shooting, Interim Chief of Police of the Metropolitan Police Department, Jeffery Carroll, said in a statement: "There had been an ongoing dispute between the suspect in this case and the building homeowner’s association regarding maintenance issues [and] mold."
The suspect's former attorney, Joel Braithwaite, who represented him in a civil case against his condo, said the proceedings had left him around $300,000 out of pocket.
He considered the condo 'his prized possession', Braithwaite added.
During the attack at VIDA Fitness, he also shot and injured four others, including two men and two women, from the balcony of his apartment, who were taken to hospital.
He also killed himself in the penthouse, following a standoff with police.

Shortly before carrying out Thursday morning's attack, Lambert shared what appeared to be a manifesto on X, referencing a report that documented suspected microbial growth, water damage and the substantial cost of repairing a wall inside his apartment.
Three firearms were found inside his home, as Carroll added: "We know that he used each of those firearms, so it does appear there was some level of planning associated with this."
He further noted that the whole shooting took place 'within less than five minutes'.
The gym where the shooting took place is also closed until further notice.
The building is situated in the heart of the US capital, with the White House roughly a five-minute drive away.
