Luigi Mangione

• 1. Introduction

  ›

  Luigi Nicholas Mangione is an American man accused of killing a health insurance executive, and the case began with three words on spent ammunition. Investigators found delay, deny and depose written on shell cases and on an ejected cartridge at the scene. The first two words echo a phrase familiar across the insurance trade. The accused was born in 1998, so he was in his twenties when he was arrested. After his arrest, strangers painted murals for him, donors sent him over a million dollars, and pollsters measured how divided Americans felt about him. How does a person with a prestigious degree and a quiet working life become the center of that argument? What did the police say they found? What have the courts decided so far? And why do some people cheer for a man charged with murder?

  Mangione was born in Towson, Maryland, on the 6th of May 1998, to Kathleen and Louis Mangione, a Baltimore-area couple of Italian descent. He has two older sisters. His paternal grandfather, Nicholas Mangione, was a successful Baltimore businessman with 10 children and 37 grandchildren. One of those grandchildren, Nino Mangione, later joined the Baltimore County Council.

  At Gilman School, an all-boys private secondary school in Baltimore, Mangione played soccer and wrestled, and he also ran track and cross country. He taught himself to code out of a love for video games. He co-founded an iOS game development company called AppRoar Studios. In 2016 he graduated as valedictorian. His speech thanked teachers, praised classmates, and acknowledged parents for an expense it called "far from a small financial investment." He said nothing about himself.

  At the University of Pennsylvania, he earned two degrees by 2020. One was a Bachelor of Science in Engineering in computer engineering, and the other was a master's in computer and information science, which he took with a focus on artificial intelligence. He graduated cum laude and minored in mathematics. In 2016 he founded UPGRADE, the university's first game development club, meant to link artists, programmers and other creative people. In a 2018 interview he described the welcome: "We don't turn people away for not having experience. Passion is what we're looking for." The club grew to about 60 members and was still active in January 2026.

  His summers and internships ran along the same lines. He did a robotics research internship at the Whiting School of Engineering at Johns Hopkins University. From May 2016 to August 2017 he was a user interface programming intern at Firaxis Games, where he worked on Civilization VI. In the summer of 2019 he served as a counselor in a Stanford University artificial intelligence program for high school students.

  In November 2020 he started working remotely as a data engineer for TrueCar. He left at the end of February 2023, telling a former classmate that the work "paid super well but was mind-numbingly boring." He said he wanted to "spend more time reading and doing yoga."

• 3. Midtown Morning

  ›

  Early on the morning of the 4th of December 2024, Brian Thompson walked toward an entrance of the New York Hilton Midtown hotel in Manhattan. Thompson was the CEO of UnitedHealthcare. He was in the city for an annual investors' meeting held by its parent company, UnitedHealth Group. A gunman shot him in the leg and the back. Video captured the attack, and Thompson died.

  Police first described the suspect as a masked white man. He fled on foot. Investigators later concluded that the gunman had reached New York by bus from Atlanta. Cameras also showed the suspect at a bus terminal after the shooting.

  The writing on the ammunition drew immediate attention. It resembled "Delay, Deny, Defend," a well-known phrase in the insurance industry. The phrase alludes to the claim that insurers try to avoid paying claims. The altered final word, depose, was left for investigators to puzzle over.

  In a wooded part of Central Park, New York police found a backpack that the gunman supposedly threw away. Inside were Monopoly money and a Tommy Hilfiger jacket. Then the trail went cold. A nationwide manhunt would last five days.

• 4. The Altoona Search

  ›

  The break came at a McDonald's on East Plank Road in Altoona, Pennsylvania, about 280 miles west of New York City. A customer there noticed a resemblance between a man in the restaurant and the images of the suspect that the New York City Police Department had released. An employee called the police. The date was the 9th of December 2024.

  When officers asked the man whether he had recently been to New York, they described him as "visibly nervous." Testifying later, the arresting officer was asked how he could tell. He answered, "I saw his fingers shaking a little bit." At about 10 a.m. police arrested the man, Mangione, for forgery and for giving false identification to law enforcement.

  They handcuffed and searched him and went through his backpack. A gun magazine turned up, so the officers decided to take everything to the Altoona police station. Rolling Stone reported what the body-worn camera footage showed. An officer, Fox, put a large McDonald's bag of evidence, including a laptop, into his SUV. His colleague, Wasser, took the backpack. Both officers switched off their cameras when they left the restaurant, leaving 11 minutes with no footage. Wasser testified that they pulled over on the way so Fox could hand her the bag.

  At the station, police said a second search of the backpack found a 3D-printed gun and a 3D-printed suppressor. They also reported a fake New Jersey driver's license in the name "Mark Rosario." A man who checked into a Manhattan hostel in late November had used an ID with that same name. Police later said the shell casings from the scene matched the gun.

  Police said they found one more item, a handwritten document of 262 words, partly about the American healthcare system. Many media outlets called it a "manifesto." NYPD Commissioner Jessica Tisch said it spoke to Mangione's "motivation and mindset." Journalist Ken Klippenstein published a transcription, and police confirmed it was authentic. Mangione had no prior criminal record. Defense lawyers contested the legality of the backpack search and moved to suppress the evidence.

  Police filed a criminal complaint at 5:13 p.m. that day, adding charges of carrying a gun without a license, tampering with records or identification, and possessing instruments of crime.

• 5. Two Courtrooms

  ›

  At 6:30 p.m. on the day of his arrest, Mangione was arraigned at the Blair County Courthouse and denied bail. He was sent to the State Correctional Institution at Huntingdon, a close-security facility. Meanwhile, NYPD officers and Manhattan prosecutors had traveled to Altoona to question him. Later that day Manhattan prosecutors issued an arrest warrant for second-degree murder, three counts of illegal weapons possession, and forgery.

  The next day, on the 10th of December, he was led into a courthouse for another hearing. He shouted at the gathered press: "Your coverage of this event is completely out of touch and an insult to the intelligence of the American people and their lived experience."

  On the 17th of December 2024, the Manhattan district attorney's office indicted him on eleven state charges. They included first-degree murder in furtherance of terrorism and two counts of second-degree murder, one of them as a killing in the act of terrorism. The rest covered weapons possession at several degrees and one count of possessing a forged instrument.

  On the 19th of December, Mangione was extradited to New York City. Federal prosecutors issued a complaint that same day charging him with four federal crimes. One was murder through the use of a firearm, a charge that carried the possibility of the death penalty. His arrival was a highly publicized perp walk, with many heavily armed officers and New York City mayor Eric Adams escorting him.

  Stanford Law School professor Robert Weisberg said the FBI and the city's prosecutors could have moved him discreetly but chose a public show. Jorge Camacho of the Yale Law School Justice Collaboratory warned that such displays can backfire when a suspect has public sympathy. On the 23rd of December, defense attorney Karen Friedman Agnifilo called it the "biggest staged perp walk I've ever seen in my career." That day he pleaded not guilty in New York Supreme Court.

  The federal case then turned on politics. President Donald Trump, in his second term, had signed an executive order requiring the death penalty wherever possible. On the 1st of April 2025, Attorney General Pam Bondi announced that prosecutors would seek it against Mangione. On the 17th of April he was formally indicted on four federal charges: murder with a firearm, another firearms offense, and two counts of stalking. The indictment said he crossed state lines to stalk and kill Thompson. He pleaded not guilty on the 25th of April at the Thurgood Marshall United States Courthouse. He is held at the Metropolitan Detention Center in Brooklyn under number 52503-511.

  On the 16th of September 2025, Judge Gregory Carro dismissed the state's two terrorism-related murder charges. He ruled that prosecutors had presented "no evidence" meeting the legal threshold of acts meant to intimidate or coerce the public. A second-degree murder charge remains.

  Suppression hearings began on the 1st of December 2025 and ran three weeks. Body camera footage played in court captured officers arguing over whether a warrant was needed to search the bag. On the 18th of May 2026, Carro ruled that the search at the McDonald's was an "improper warrantless search." Evidence found there was suppressed, including the handwritten document. Items from the station, including the alleged 3D-printed gun, were allowed. He tentatively set the state trial for the 8th of September 2026.

  In the federal case, Judge Margaret Garnett acted on the 30th of January 2026. She dismissed the murder-by-firearm charge and a firearms offense as "legally incompatible" with the two stalking charges. The death penalty is no longer possible. She allowed evidence from the backpack at trial. Hundreds of potential jurors were to receive questionnaires, with in-person questioning scheduled to begin on the 5th of October 2026 and opening statements on the 26th of October.

• 6. Lawyers and Donors

  ›

  Mangione retained Thomas Dickey for his Pennsylvania case. On the 13th of December 2024 he hired Karen Friedman Agnifilo for New York. She is a former Manhattan district attorney's office prosecutor and a former legal analyst at CNN. He later brought on prison consultant Craig Rothfeld to help with matters connected to his incarceration. He pleaded not guilty to every charge in Pennsylvania and New York.

  When the Justice Department announced it would seek the death penalty, his New York defense team asked the judge to block it. They called the decision a "publicity stunt." They argued it was "consistent with the new culture of the highest levels of the Justice Department, one that values personal will over process, publicity over discretion and partisan politics over justice."

  Money followed his supporters' sympathy. By the 13th of December 2024, GoFundMe had removed fundraisers set up for him, citing its rule against raising money for the legal defense of violent crimes. A GiveSendGo campaign stayed up. By January 2026 it had raised over US$1.4 million. Donors named the politicization of the case, the possible death penalty, due process, and frustration with the healthcare system.

  Agnifilo told Newsweek that Mangione knew of the fund and "very much appreciates the outpouring of support." She said he planned to use it to fight "all three of the unprecedented cases against him." On the 14th of February 2025, his New York team launched a website with updates, citing an "extraordinary volume of inquiries."

• 7. Pain, Books, Silence

  ›

  Mangione holds dual American and Italian citizenship, a status he has had since 2008. In January 2022 he moved to Honolulu and lived at Surfbreak, a co-living space, until June. A devoted reader, he co-founded a book club there in 2023. The club ended when he left Hawaii later that year.

  His health appears throughout his online writing. He wrote about getting Lyme disease at age 13 and about brain fog since high school. He asked for advice online about irritable bowel syndrome and visual snow. At Penn he wrote that he had thought about dropping out as his health worsened but decided against it. "Staying in college has at least let me maintain some semblance of normality," he said.

  He also wrote that he has spondylolisthesis, a spinal condition. In Hawaii a surfing mishap made his back pain worse, and he voiced his worry to others. In July 2023 he had spinal fusion surgery and posted that it went well. Police have stated that UnitedHealthcare did not insure him.

  In February 2024, he told a friend he was "going backpacking for awhile." He traveled alone through East and Southeast Asia, including Japan and Thailand. In June 2024 he stopped posting on social media. His family asked his past friends for help finding him, without success. On the 18th of November 2024, his mother reported him missing to the San Francisco Police Department. The family had not heard from him since July. She chose that department because she believed he lived in San Francisco and still worked for TrueCar, which had an office there.

  After the arrest, news outlets read his accounts closely. His Twitter handle, PepMangione, covered religion, history, ethics and politics. Analysts called him fascinated by AI and decision theory, pro-technology but anti-smartphones, and secular and scientific in outlook. He showed skepticism toward both Joe Biden and Donald Trump. Reports said he followed Alexandria Ocasio-Cortez and Robert F. Kennedy Jr., among others. Time said it could not tell whether his views leaned left or right. The Spectator said his worldview was not pinned to a standard left-right axis. Jacobin described a hodgepodge of beliefs. Maryland voter records list him as having no party affiliation.

  He also posted a Goodreads review of Industrial Society and Its Future by Ted Kaczynski, the "Unabomber." The review called Kaczynski "rightfully imprisoned" and criticized his violence against innocent people. It also said the text "reads like a series of lemmas" and gave it four out of five stars.

• 8. The Folk Hero Question

  ›

  Rolling Stone called Mangione the "most debated and polarizing murder suspect in recent history." The hashtag "#FreeLuigi" and its variants were shared over 50,000 times on Twitter. Supporters called him a modern-day Robin Hood. Memes spread, and merchandise appeared on Etsy and Amazon. A billboard went up in Riverside County, California, and a mural appeared in Seattle. During a live NewsNation interview at SCI Huntingdon, inmates could be heard shouting "Free Luigi" from their cells.

  On the 14th of February 2025, Mangione made his first official statement since his arrest. He thanked the public and said that "the support has transcended political, racial, and even class divisions."

  Charlie Warzel of The Atlantic wrote that, to some, Mangione is an "expression of the depth of righteous anger present in American life right now, a symbol of justified violence." After the killing, anger flared online at Thompson, UnitedHealth and the health insurance system, and many people praised the shooting. A December 2024 poll from NORC at the University of Chicago found that most American adults believed health insurers bore a moderate amount or a great deal of responsibility for Thompson's death, because of coverage denials or profits. The case has strengthened calls for reform.

  Polling shows a split by age. An Economist/YouGov poll in December 2024 found 43% of citizens viewed him unfavorably and 21% favorably. Support ran higher among those aged 18-29 and those who called themselves very liberal. A poll that month by the Center for Strategic Politics found 61% negative and 19% positive. It also found that younger respondents viewed him far more favorably than Thompson and UnitedHealthcare.

  Some acts of violence have been linked to him. Prosecutors alleged that the man accused of starting the Palisades Fire in January 2025 was fascinated with Mangione and had searched for terms such as "free Luigi Mangione." In April 2026, a Los Angeles warehouse was allegedly set on fire, causing more than $600 million in damage. Authorities said the suspect was "motivated by anti-capitalism sentiment" and likened himself to Mangione.

  Attention also turned to his looks. Kara Alaimo, writing in Time, said he had become "somewhat of an online sex symbol." After his court appearance on the 23rd of December 2024, users misidentified the brand of his burgundy sweater as Maison Margiela. It was a washable Merino crewneck from Nordstrom, and it sold out in one day. After a February 2025 hearing, photos of his shackled ankles in brown loafers went viral. Searches for "luigi mangione loafers" jumped 1,400% and for "luigi mangione ankles" 500%. In early September 2025, the Chinese retailer Shein listed a shirt with an edited, AI-generated image of Mangione modeling it, then removed it. Criminologist Diana Rickard called him a "fashion folk hero."

  He has been the subject of several documentaries, news specials and a satirical comedy musical, and a song carries his name. In September 2025, Ryan Murphy, creator of the Netflix anthology Monster, expressed interest in a season about Mangione. In the 2025 Simpsons episode "¡The Fall Guy-Yi-Yi!", Bart says, "What's the use of having a badass in the family if you can't brag about him? Now I know how the Mangiones feel."
