Man Charged with Impersonating FBI Agent in Attempt to Free Accused UnitedHealthcare CEO Killer

A Minnesota man has been accused of attempting to secure the release of Luigi Mangione, the man charged with the murder of UnitedHealthcare CEO Brian Thompson, by falsely claiming to be an FBI agent. The incident unfolded at the Metropolitan Detention Center in Brooklyn on Wednesday, raising serious security concerns.
Mark Anderson, 35, was arrested after presenting a Minnesota driver’s license and claiming possession of weapons to prison staff, according to a complaint filed in the U.S. District Court for the Eastern District of New York. He allegedly asserted he had paperwork “signed by a judge” authorizing Mangione’s release.
Anderson’s attempt to gain access to Mangione was quickly thwarted when prison workers requested to verify his credentials. According to the court document, Anderson “claimed to be an FBI Agent” and displayed numerous documents that appeared to be related to claims against the United States Department of Justice. He reportedly “displayed and threw at [Bureau of Prisons] officers” these documents during the confrontation.
A search of Anderson’s backpack revealed a barbecue fork and a “round steel blade” resembling a pizza cutter. Law enforcement sources indicate Anderson had recently traveled to New York from Minnesota seeking employment, and had been working at a pizzeria prior to the incident.
The Mangione Case: A High-Profile Murder and Political Undertones
Luigi Mangione, 27, has been detained at the Brooklyn federal lockup since December 2024, following his arrest in connection with the death of Brian Thompson. Thompson was fatally ambushed in midtown Manhattan. Mangione faces charges in New York for second-degree murder, as well as four federal charges, including two counts of stalking, one count of murder, and one count of using a firearm in the commission of a murder. He has entered a plea of not guilty to all counts.
The case has garnered national attention, particularly after U.S. Attorney General Pam Bondi announced in April the government’s intention to seek the death penalty. Bondi characterized the murder as “an act of political violence” and a “premeditated, cold-blooded assassination that shocked America.”
Concerns Over Radicalization and Public Support
Federal prosecutors have expressed concerns that Mangione continues to pose a threat to public safety, arguing in an August filing that he is actively attempting to inspire others to emulate his actions. “Simply put, the defendant hoped to normalize the use of violence to achieve ideological or political objectives,” the filing stated. Prosecutors noted that since the murder, some individuals identifying as supporters of Mangione have begun to view violence as an acceptable means of political expression.
Despite the severity of the charges, Mangione’s legal defense fund has reportedly raised over $1 million in donations. This influx of support is attributed to public anger surrounding the nation’s for-profit medical system, suggesting a degree of sympathy for the accused among those critical of healthcare practices.
The investigation into Anderson’s motives and any potential connections to Mangione or his supporters is ongoing. This incident underscores the challenges faced by law enforcement in securing correctional facilities and addressing the potential for politically motivated violence.
