Where Is Luigi Mangione Now? All About the Accused Assassin's 'Well-Adjusted' Life in Prison By Emily Blackwood

Five days after UnitedHealthcare CEO Brian Thompson was killed outside of a New York City hotel, police arrested Luigi Mangione as their prime suspect. In the months that followed the December 2024 killing, the former data engineer’s notoriety has only grown as he faces multiple state and federal murder charges.

A billboard portraying him as a saint went up in Lower Manhattan, and supporters — some dressed as Luigi from Super Mario Bros. — have turned up at nearly all of his court appearances. He even had to ask fans to curb the flood of photos and books they send him.

Mangione previously pleaded not guilty to the federal and murder charges against him in April 2025. He was also indicted on two terrorism charges in New York, but those were dismissed in September 2025.

So, where is Luigi Mangione now? Here’s everything to know about the alleged killer’s case and his life since being accused of murdering Brian Thompson.

Luigi Mangione allegedly shot and killed Brian Thompson in December 2024

On Dec. 4, 2024, Thompson was killed by a masked gunman outside of a Manhattan hotel. Video surveillance showed the assassin firing at least three bullets at the UnitedHealthcare CEO from behind as he arrived for an investor conference.

Bullet casings found at the scene were engraved with the words “deny,” “defend” and “depose.” The phrase is similar to the healthcare industry’s description of a strategy for rejecting claims, which is “delay, deny, defend.”

Authorities arrested Mangione five days later after he was located eating breakfast at a McDonald’s in Altoona, Pa. He “became quiet and started to shake” when authorities asked him if he had been to New York recently, according to the criminal complaint.

His alleged manifesto said the “parasites simply had it coming” 

During his arrest, police collected a 9mm ghost gun, fake IDs and a notebook they alleged described Mangione’s intent to “wack” an insurance executive (“wack” is an apparent misspelling of “whack”). The alleged manifesto was highly critical of the American health insurance industry and revealed that he had allegedly written about UnitedHealthcare’s investor conference six weeks before Thompson’s murder.

“I finally feel confident about what I will do,” Mangione allegedly wrote in an August 2024 entry. “The details are coming together. And I don’t feel any doubt about whether it’s right/justified. I’m glad in a way that I’ve procrastinated [because] it allowed me to learn more about [UnitedHealthcare].”

He continued, “The target is insurance. It checks every box.”

In December 2024, independent journalist Ken Klippenstein published a transcript of the legible parts of the alleged manifesto. Newsweek later confirmed its authenticity with the police.

“I do apologize for any strife of traumas but it had to be done,” Mangione allegedly wrote in the document addressed to “the Feds.” “Frankly, these parasites simply had it coming.”

He is facing multiple state and federal charges

Days after his December 2024 arrest, Mangione was charged with one count of murder, two counts of second-degree criminal possession of a weapon, one count of third-degree criminal possession of a firearm and one count of second-degree possession of a forged document in New York. The state later indicted him on a second-degree murder charge as a “crime of terrorism.”

He was also charged with one felony count of forgery, one felony count of carrying a firearm without a license, one misdemeanor count of possessing instruments of a crime, one misdemeanor count of tampering with records or identification and one misdemeanor count of false identification to law enforcement authorities in Pennsylvania.

On Dec. 19, 2024, the Department of Justice charged Manigone with one count of using a firearm to commit murder, one count of interstate stalking resulting in death, one count of stalking through use of interstate facilities resulting in death and one count of discharging a firearm that was equipped with a silencer in furtherance of a crime of violence.

In April 2025, he pleaded not guilty to both the state and federal charges against him.

He has not entered a plea for his charges in Pennsylvania.

Prosecutors have said they’re seeking the death penalty

Hours before Manigone submitted his not guilty plea, federal prosecutors formally submitted their intent to seek the death penalty against him. The DOJ filing read that the alleged assassin sought to “amplify an ideological message” and “provoke broad-based resistance to the victim’s industry.”

“[Mangione] presents a future danger because he expressed intent to target an entire industry, and rally political and social opposition to that industry, by engaging in an act of lethal violence,” the filing read.

In response, Mangione’s lawyers called the death penalty filing a “political stunt.”

Why were Luigi Mangione’s terrorism charges dropped?

On Sept. 16, a New York state judge dropped the two terrorism charges against Mangione, citing that he found the evidence presented to the grand jury to be “legally insufficient.”

“There is no indication in the statute that a murder committed for ideological reasons (in this case, the defendant’s apparent desire to draw attention to what he perceived as inequities or greed within the American health care system), fits within the definition of terrorism. Without establishing the necessary element of an intent to intimidate or coerce,” Judge Gregory Carro said in his written decision.

The judge kept the remaining counts, which included a second-degree murder charge.

Where is Luigi Mangione now?

The accused murderer has been held pretrial at the Metropolitan Detention Center in Brooklyn, N.Y., since his arrest in December 2024. It is the same facility where Sean “Diddy” Combs has been held since 2024.

MDC has a reputation for extreme violence amongst inmates and horrid conditions, per PBS. However, Mangione appears to be well settled, federal prison consultant Sam Mangel told PEOPLE in June 2025.

“He seemed to be perfectly well adjusted,” he said.

Mangione has been working as an orderly in the prison, responsible for cleaning showers and common areas.

“There’s very few jobs somebody can get in a detention center because of the amount of restriction,” Mangel told PEOPLE. “Orderly tends to be one of the only ones, and does require mop and bucket,” adding that inmates “can be very fastidious, and they like clean showers.”

The hearings on Mangione’s state charges will begin on Dec. 1, and he’ll return to the courtroom four days later to set the trial date for his federal case. He was also ordered to appear in a Pennsylvania courtroom for a pretrial motion hearing on Nov. 7, ABC News reported.
