THE ASSASSINATION FAN BASE: What the Logan Circle Shooter Told Me.
Matt Lambert, a former emergency room physician and health care technology executive, shot five people and then himself on Thursday in D.C., apparently motivated by a bitter, ongoing and all-consuming legal dispute with the Metropole Condominium Association and the building’s property manager.
The back-and-forth had been dragging on for more than a year, draining his retirement savings and fueling a deepening desperation.

In a series of interviews in late November and December 2025 — including two visits inside his gutted penthouse at the Metropole on 15th Street Northwest — Lambert described how a dispute over severe water leaks and black mold had turned into “psychological warfare” between himself, building manager James Stuart, the management company EJF Real Estate Services and their insurance defense attorneys.
“It’s affected every part of my life — my sleep, dietary habits,” Lambert told me in December. “I pride myself on my resilience, and I’ve been kind of surprised at how much it has been affected.”
On Thursday, D.C. police said, Lambert shot and killed Stuart at the VIDA Fitness Center located on the ground floor of the building in a targeted attack just before 8 a.m., then shot four more people in the vicinity and barricaded himself in his apartment before shooting and killing himself. Of the other four people who were shot, one was in critical condition, while three others had non-life-threatening injuries.
While at no point in the reporting process did Lambert give any indication he would resort to violence, he did frequently use intense, combative language — and at one point, his frustration veered into what at the time felt like dark humor. During a December visit with a neighbor, Lambert criticized the condo association’s legal strategy by making an offhand reference to Luigi Mangione, the suspect in the 2024 shooting death of UnitedHealthcare’s CEO who is accused of inscribing “delay, deny, depose” on his ammunition.
“What are they called? Delay, deny, defend … the Luigi three?” Lambert said.
The left knew that elevating Mangione into a folk hero would inspire plenty of others to go down that dark route, and didn’t care.

And note this, “Lambert reached out to me in late 2025 when I was a reporter at The Washington Post, pitching a story about how his million-dollar Logan Circle penthouse had been rendered unlivable. I continued reporting the story into the new year, but the article was abandoned when I was laid off from the Post in early 2026.”
