The deranged Washington, DC, doctor who gunned down his building manager Thursday over his moldy $1.1 million penthouse chillingly knew the victim’s morning routine — and name-dropped Luigi Mangione.
In an interview with a then-Washington Post reporter, Matt Lambert railed about the building manager-turned-slay victim James Stuart, saying the fight over the mold that turned his 7th-floor home into a hell hole had turned into “psychological warfare,” The Washington Sun reported Thursday.
He also eerily noted to a fellow resident who had also been waiting for repairs to be done to his apartment: “If you want to see the building manager he comes in the gym about 8 o’clock.”
Lambert used a handgun to kill Stuart just after 8 a.m. inside the building’s ground-floor Vida Fitness in the ritzy Logan Square neighborhood.
“There had been an ongoing dispute between the suspect in this case and the building homeowner’s association regarding maintenance issues [and] mold,” Interim Chief of Police of the Metropolitan Police Department Jeffery Carroll confirmed at a press conference Thursday.
The crazed killer also referenced Mangione, the UnitedHealthcare CEO killer, in conversations with the journalist, Michael Brice-Saddler, who penned a piece about his encounter with the now-dead ER doctor for The Washington Sun.
Last December, Brice-Saddler recalled Lambert mentioning the three words inscribed on Mangione’s bullets he used to kill Brian Thompson.
“What are they called? Delay, deny, defend … the Luigi three?” Lambert said at the time.
The DC gunman also mentioned Mangione on X, as he ripped management for dragging its feet on repairing the Logan Circle building.

“After months of ‘Luigi’ tactics (delay, deny, defend) by the HOA, we were finally able to submit an independent engineering report into the record,” Lambert wrote on Oct. 1.
“The report addresses 704, the facade rehabilitation more broadly , and lists other units affected. When the time is right, I will share the report on X, with other Metropole owners, and with Logan Circle realtors.”
He also shot and injured four others, including two men and two women, from the balcony of his apartment who were rushed to the hospital.
Lambert then killed himself in the mold-ridden penthouse following an hour-long standoff with cops where he railed about “the HOA and challenges” with it, Carroll noted.
Speaking with Brice-Saddler in December, Lambert stressed the ongoing mold battle has “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,” the doctor told the then-WaPo reporter.
Lambert also hauntingly referenced Sun Tzu’s “The Art of War,” noting that he goes “through every emotion every day on this.”
“Do I keep fighting? Do I not fight?” he questioned. “And ‘The Art of War’ talks about, you know, the battle’s won before it’s ever fought.”
“It says if you’re going to commit, don’t half commit, fully commit,” Lambert eerily told Brice-Saddler.
Moments before Thursday morning’s attack, Lambert posted a twisted “manifesto” on X, citing a report which detailed “suspected microbial growth” along with water intrusion and a hefty bill to “rehabilitate” the wall of his home.
The crazed physician sued the homeowners’ association of his swanky building over the black mold and other problems last year.
“They’re trying to make me quit. They’re trying to make me go broke,” Lambert said of his legal fight in an interview with Brice-Saddler.
“If I come out of this and I don’t get a satisfactory outcome, I won’t have a bunch of money, but I can live with that better than rolling over. … They don’t have my permission to treat me this way,” the deranged gunman warned.
