Almost a year before the tragic shooting in Logan Circle, D.C., perpetrator Matt Lambert mentioned Luigi Mangione, the leftist terrorist known for murdering UnitedHealthcare CEO Brian Thompson, during an interview about his condo problems.
In late 2025, Lambert talked to then-Washington Post reporter Michael Brice-Saddler about the incessant water leaks and mold issues plaguing his unit. He described the legal maneuvers from the condo association as “psychological warfare.”
Lambert made a cryptic comment regarding the Metropole Condominium, using the phrase “the Luigi three”—a reference that echoes the actions of Mangione. Brice-Saddler now works with the Washington Sun.
This phrase closely mirrors language linked to Mangione, who infamously shot Thompson in Manhattan. Investigators found ammunition with inscriptions like “deny” and “defend,” which are often used to describe tactics in handling insurance claims.
Lambert’s comments cleverly framed his grievances with the association’s repairs in this context. Brice-Saddler later noted that Lambert did not indicate any intention of violence during their conversations.

Lambert continued to reference Mangione publicly. In an October 2026 post on X, he criticized the homeowners’ association for its “Luigi” tactics (delay, deny, defend) while sharing plans for an independent engineering report addressing issues in the building.
The violent incident unfolded at the VIDA Fitness gym on November 12, around 8 a.m. Lambert, aged 55, shot and killed James Stuart, the building manager, and subsequently injured others.
Following the shooting, he fortified himself in his apartment, expressing frustrations over his issues with the building’s owners for about an hour before taking his own life.
A former emergency room physician, Lambert had two decades of experience in healthcare technology. He bought his luxury unit for approximately $1.1 million in 2016 and authored several healthcare-related books, including Unrest Insured.
He contended that rehabilitation work between 2023 and 2024 caused severe water intrusion and mold problems. Lambert reported spending nearly $200,000 by late 2025 on legal and engineering fees, having stripped his unit to reveal damage while living minimally.
In March 2025, he filed a suit in D.C. Superior Court citing negligence and nuisance, but the condo association refuted his claims. Lambert conveyed to Brice-Saddler how the ordeal disrupted his life and mental health, likening his reputation in the building to being “radioactive.” He actively disseminated his message via social media and flyers.
