Emergency room doctor Matt Lambert, who allegedly opened fire at the VIDA Fitness Center in Washington, D.C., referenced Luigi Mangione in a pre-shooting interview, according to The Washington Sun. Lambert, who was reportedly in a dispute with his apartment building manager James Stuart, discussed the legal tactics of his condo association during a conversation with neighbor Michael Brice-Saddler in late 2025.
Reference to Mangione’s Legal Strategy
Lambert allegedly described the condo association’s legal approach as “Delay, deny, defend … the Luigi three,” a phrase linked to Mangione, who inscribed the words on the ammo he allegedly used to kill UnitedHealthcare CEO Brian Thompson, according to The Associated Press.

Lambert also described the disputes between Stuart, the management company, and their attorneys as “psychological warfare,” claiming the conflict had severely impacted his personal life, including his sleep and dietary habits. He cited black mold and severe water leaks in his million-dollar apartment unit as the root of the ongoing legal battle with Stuart.
Online Campaign and Shooting Details
Lambert started an X account, “Of Mice and Mold,” to document the issues with his apartment. A Nov. 12 post on the account reads, “My manifesto is an engineering report,” including screenshots of third-party mold testing. The shooting occurred shortly after 8:00 a.m. at the VIDA Fitness Center, where Lambert used the facility’s shower following a dispute over moisture in his unit, as reported by The Washington Sun.
The D.C. Metropolitan Police Department (MPD) confirmed that Lambert killed Stuart and injured four others during the shooting. Interim Police Chief Jeffery W. Carroll stated that the shooter was contained and died of a self-inflicted gunshot wound. The incident has sparked renewed interest in the connection between Lambert’s pre-shooting comments and the legal tactics of Mangione, who is currently facing trial in Louisiana over alleged involvement in the UnitedHealthcare CEO murder.
