Ivy League suspect in UnitedHealthcare CEO's killing pleads not guilty

Luigi Mangione, the individual accused of taking the life of UnitedHealthcare CEO Brian Thompson on December 4 in Manhattan, entered a plea of not guilty in a Manhattan court in New York State on Monday morning.

Mangione, aged 26, faced 11 charges in court, which included first-degree murder, second-degree murder as a terrorist act, and various weapon-related charges. Should he be found guilty of the most severe offense, he could potentially be sentenced to life in prison without the possibility of parole.

The charges encompass one charge of first-degree murder, categorized as a class A-I felony; two counts of second-degree murder, also class A-I felonies; two charges of illegally possessing a weapon in the second degree, classified as a class C felony; four charges of unlawfully possessing a weapon in the third degree, a class D felony; one charge of being in possession of a weapon in the fourth degree without authorization, a class E felony; and one charge of having a forged document in the second degree, categorized as a class D felony.

Mangione’s attorney, Karen Friedman Agnifilo, claimed during the court appearance that statements made by government officials, such as New York City Mayor Eric Adams, were putting her client’s right to a fair trial in jeopardy.

“I’m very concerned about my client’s right to a fair trial,” Agnifilo said, raising further concerns over Mangione’s treatment since he arrived in New York City.

“He’s a young man and he’s being treated like a human ping pong ball” between two warring jurisdictions, Agnifilo said, adding that the overwhelming police presence at his arrival in New York City on Thursday was the worst perp walk she’d ever seen.

“This has to stop and my client is entitled to a fair trial and presumption of innocence,” Agnifilo said, vowing to fight the charges. 

Mangione will remain in federal custody until a transfer is worked out between state and federal authorities. His next court date was scheduled for Feb. 21.

As Mangione departed the court alongside an escort of police, he appeared to raise his eyebrows and shake his head in response to a question from the media.

Protesters were seen outside the courthouse chanting “free Luigi” and holding signs that read: “United States healthcare stole my livelihood prosecute, malicious profiteers” and “family court has blood on their hands.”

Since Mangione’s capture, both his alleged actions and physical appearance captivated users on social media, which erupted with positive posts about the murder suspect.

New York prosecutors say Mangione plotted to travel to New York, find Thompson, a Minnesota resident in town for UnitedHealthcare’s annual shareholder conference, and kill him. Mangione allegedly shot Thompson from behind with a 3D-printed ghost gun and suppressor. 

Thompson was appointed the CEO of UnitedHealthcare in April 2021. He is survived by his wife Paulette “Pauley” Thompson, 51, and their two children.

Prosecutors say Mangione fled New York City within an hour after the crime and traveled to Altoona, Pennsylvania.

Altoona police arrested Mangione in a McDonald’s five days later on Dec. 9, after receiving a tip from an employee. The suspect allegedly presented local police with a fake ID and appeared to start shaking when they asked if he had been in New York recently.

Officials also found a handwritten manifesto condemning the health care industry, as NYPD Chief of Detectives Joseph Kenny previously told Fox News. The manifesto specifically mentioned UnitedHealthcare.

While officials have not commented on an official motive, the public has speculated that the suspect had strong grievances with both the health care and insurance industries.

Fox News’ Maria Paronich, Grace Taggart and Audrey Conklin contributed to this report.
