Thompson's death received widespread attention in the United States and led to polarized reactions.[21] Several public officials expressed dismay and offered condolences to Thompson's family, while many used the event to call attention to the practices of the US health insurance industry. Opinion polls have shown that a majority or plurality of American adult respondents find the killing unacceptable, with younger and more left-leaning respondents more likely to view the killing as acceptable or to sympathize with the killer. On social media, reactions to the killing included widespread contempt and mockery toward Thompson and UnitedHealth Group, sympathy and praise for Mangione, and broader criticism of the American healthcare system and health insurance industry – primarily regarding claim denial practices.[22][23] Inquiries about protective services and security for CEOs and corporate executives surged following the killing.[24]
Background
Thompson and UnitedHealthcare

Brian Thompson was the chief executive officer (CEO) of UnitedHealthcare, the insurance arm of UnitedHealth Group, from April 2021 until his death. He had worked for UnitedHealthCare since 2004.[4][5] UnitedHealthcare insures 49 million Americans and generated $281 billion in revenue for the 2023 fiscal year.[25] Under his leadership, UHC's profits increased from $12 billion in 2021 to $16 billion in 2023.[26] At the time of Thompson's death, the company was the largest health insurer in the United States.[27]
UnitedHealthcare has repeatedly faced criticism for its approach to handling claims.[28] It and other insurers were named in an October 2024 report from the United States Senate Homeland Security Permanent Subcommittee on Investigations showing a surge in prior authorization denials for Medicare Advantage patients.[25] Reports of increasing rates of prior authorization denials prompted investigations by ProPublica and the United States Senate, investigations which were described as a "stain" on Thompson's time of leadership by Fortune.[26] According to Thompson's widow, he had been receiving threats related to a "lack of [insurance] coverage".[29]
Suspected assailant's preparations
The suspect arrived in New York City on November 24, 2024, on a Greyhound bus. The bus route began in Atlanta, Georgia, but authorities do not know from which city or town he boarded.[30][31] He checked into the HI New York City Hostel on the Upper West Side of Manhattan on November 24, 2024 with a falsified New Jersey identification card; he paid for his stay in cash.[32] He stayed all but one night of the 10 days he was in New York City at the hostel, checking out on December 3, 2024.[31]

Investigation

Three fired
A water bottle, candy wrapper, and phone were recovered from the scene and are believed to be connected to the shooter.[58] Police said they believed they found the shooter's backpack in Central Park on December 6, 2024.[59] The backpack contained a Tommy Hilfiger jacket and Monopoly money.[60]
The New York City Police Department offered a reward up to $10,000 for information about the shooter on December 4, 2024.[61] The following day, authorities released images of a suspect taken by surveillance cameras at the hostel and a Starbucks café.[62] Two stills show the suspect's face, including one with him smiling widely at a female desk attendant at the hostel.[63][58] Sources told CBS the front desk worker asked to "see his pretty smile."[15] The FBI joined the investigation and separately offered a reward of up to $50,000 for information leading to an arrest and conviction.[64]
The shooter was described by police as a white man, approximately 6 ft 1 in (185 cm) tall, wearing a light brown or cream-colored hooded jacket, dark pants, and black sneakers with white soles. He had a gray backpack and concealed his face with a black face mask.[35][46][65][66] Police said the suspect appeared to be proficient in the use of firearms[34] and was described as being "extremely camera savvy".[67]
Suspect

Luigi Mangione was born in Towson, Maryland[68] on May 6, 1998.[69][70][71][8] He graduated from the University of Pennsylvania.[72] Prior to his arrest, Mangione had no criminal record.[73] His last known residence was in Honolulu, Hawaii.[74] In November 2024, Mangione was reported missing by his mother, who said the family had not heard from him since July of that year.[75]
Arrest and charges
Local police in
Mangione was charged in
Mangione hired Karen Friedman Agnifilo, former prosecutor at the Manhattan District Attorney's Office and former legal analyst with CNN, as his New York case defense attorney.[86] On December 17, New York prosecutors charged him with first-degree murder as murder committed in furtherance of terrorism.[a][87] This charge and indictment modified the murder charge with which he was already charged, as the charge of murder as an act of terrorism holds more weight than just a simple murder charge.[88][89] He was extradited to New York on December 19 and transferred to the Metropolitan Detention Center in Brooklyn following his first appearance in the Manhattan federal court.[90][91][92] On December 23, Mangione pleaded not guilty to all New York state charges.[93][94] In addition to the eleven state charges, he faces four new federal charges, including two counts of stalking, a new firearms-related offense, and murder through use of a modified firearm.[16][95] On April 1, U.S. Attorney General Pam Bondi directed prosecutors to seek the death penalty in the federal case. The state charges carry a maximum sentence of life imprisonment.[20]
Handwritten letter
Upon Mangione's arrest, police said they found in his possession a 262-word handwritten document, which many media outlets characterized as a "manifesto". According to NYPD commissioner Jessica Tisch, the handwritten document spoke to Mangione's "motivation and mindset".[96][97] Journalist Ken Klippenstein published a transcription of the document police said was found on Mangione. Police confirmed that the transcription was legitimate.[98][99][100] The document reads as follows:
To the Feds, I'll keep this short, because I do respect what you do for our country. To save you a lengthy investigation, I state plainly that I wasn't working with anyone. This was fairly trivial: some elementary social engineering, basic CAD, a lot of patience. The spiral notebook, if present, has some straggling notes and To Do lists that illuminate the gist of it. My tech is pretty locked down because I work in engineering so probably not much info there. I do apologize for any strife of traumas but it had to be done. Frankly, these parasites simply had it coming. A reminder: the US has the #1 most expensive healthcare system in the world, yet we rank roughly #42 in life expectancy. United is the [indecipherable] largest company in the US by market cap, behind only Apple, Google, Walmart. It has grown and grown, but as [sic] our life expectancy? No the reality is, these [indecipherable] have simply gotten too powerful, and they continue to abuse our country for immense profit because the American public has allwed [sic] them to get away with it. Obviously the problem is more complex, but I do not have space, and frankly I do not pretend to be the most qualified person to lay out the full argument. But many have illuminated the corruption and greed (e.g.: Rosenthal, Moore), decades ago and the problems simply remain. It is not an issue of awareness at this point, but clearly power games at play. Evidently I am the first to face it with such brutal honesty.[101]
The complaint filed by the U.S. Attorney's Southern District of New York calls the letter "The Feds Letter" because it is addressed "To the Feds."[102] The complaint was unsealed on December 19, 2024.[103]
Possible motives
As of mid-December 2024, investigators' theory of Mangione's motive is ill will towards the health insurance industry.[104] Police believe the motive was partially related to an injury that Mangione had suffered that caused him to visit the emergency room in July 2023. Online photos posted by Mangione showed screws in his back, though the identity of the person pictured is unverified.[105][104] Mangione wrote online that he had spondylolisthesis, a lower back condition.[106] Sources told CBS they believed Mangione had resentment towards UnitedHealthcare as well as other health insurance companies.[15] According to UnitedHealthcare, he was not one of their customers.[107] New York Police Chief of Detectives Joseph Kenny believes Mangione may have targeted them because of the company's size.[107]
Police believe that Mangione was inspired, in part, by Ted Kaczynski's Industrial Society and Its Future.[14] Mangione's account posted a Goodreads review of Industrial Society and Its Future,[108] describing Kaczynski as "rightfully imprisoned" and was critical of his use of violence against innocent individuals. The review, which gave the manifesto four out of five stars, also contained a quote that the reviewer claimed to have found online. The quote contained the lines "'Violence never solved anything' is a statement uttered by cowards and predators," and "When all other forms of communication fail, violence is necessary to survive."[109][110][111]
A report on the killing by the New York City Police Department's Intelligence & Counterterrorism Bureau[112] was obtained by independent journalist Dan Boguslaw, and published in full by Klippenstein on December 26. The intelligence report focused on Mangione's motive and people who express sympathy for him, whom the bureau labeled as "extremists". The report assessed that Mangione was motivated by "what he perceives as a 'parasitic' health insurance company and industry as a whole, as well as broader objections to corporate greed and a concern for modern society".[113]
Reactions
Public and online


Many social media users expressed their contempt for Thompson, UnitedHealthcare, and the nation's health insurance system while expressing sympathy for and praising the assailant for his actions.[114][115][116][117] Social media users shared stories of health insurance claim denials online,[118][119][120] and joked about the killing with memes and gallows humor.[121] NBC News reported that the "main theme animating many of the posts about the Thompson killing was that UnitedHealthcare and other insurance companies harm and kill Americans by denying coverage in the name of profit".[122] One physician told The Daily Beast that they believed the perpetrator should be brought to justice, but they also stated that Thompson's role as CEO had led to a great amount of suffering and loss of life, which he described as "on the order of millions", adding that "[it is] hard for me to sympathize when so many people have suffered because of his company".[123] Internet culture journalist Taylor Lorenz analyzed the responses on social media and wrote on her blog: "No, that does not mean people should murder them. But if you've watched a loved one suffer and die from insurance denial, it's normal to wish the people responsible would suffer the same fate."[124]

According to the
Crowdfunding
A GiveSendGo fundraiser has remained live,[151] and as of March 2025, it has raised over US$720,000 from crowdfunded donations.[152] Several donors have cited the "politicization" of the death penalty and the case, due process, and their frustration with the healthcare system as their reasons for donating.[153][154] On February 14, 2025, Mangione's New York legal defense team created a website to provide information about his cases due to the "extraordinary volume of inquiries and outpouring of support". The site shared an official message from Mangione, who expressed his gratitude for the public's support, stating that "the support has transcended political, racial, and even class divisions".[155][156]
Health insurance corporations

After Thompson's death, UnitedHealthcare's parent company, UnitedHealth Group, published a statement on Facebook detailing the death and their official condolences. Though the post's comment section was deactivated, over 100,000 Facebook users responded to the post with a "Haha" (or "laughing") reaction.[157][122][158] UnitedHealth Group CEO Andrew Witty defended the company's claim denial practices in an internal video which was leaked after the fatal shooting of Thompson. Recorded on December 5, the day after Thompson's death, Witty emphasized the company's role in ensuring "safe and appropriate" care and that the insurance giant will continue to prevent "unnecessary care".[159] Two months after the shooting, UnitedHealth hired a defamation law firm to take action against social media posts critical of the company.[160]

Politicians
Public officials including Minnesota governor Tim Walz and Senator Amy Klobuchar expressed dismay and offered condolences to the family; Walz said that he knew Thompson.[166] Maryland state delegate Nino Mangione, cousin of Luigi Mangione said, "Our family is shocked and devastated by Luigi's arrest. We offer our prayers to the family of Brian Thompson, and we ask people to pray for all involved".[167]
Outgoing White House Press Secretary Karine Jean-Pierre said that the government said that "violence to combat any sort of corporate greed is unacceptable".[168] Pennsylvania Governor Josh Shapiro commented that "Some attention in this case, especially online, has been deeply disturbing, as some have looked to celebrate instead of condemning this killer."[169] At the time President-elect Donald Trump also condemned the killing and called celebration of Mangione "a sickness".[170] Outgoing Department of Homeland Security secretary Alejandro Mayorkas said that social media rhetoric about the killing was alarming, and that "It speaks of what is really bubbling here in this country, and unfortunately we see that manifested in violence, the domestic violent extremism that exists".[171][172]
California Democratic House representative Ro Khanna said, "There is no justification for violence" and added that the public reaction to Thompson's killing did not surprise him because "We waste hundreds of billions a year on health care administrative expenses that make insurance CEOs and wealthy stockholders incredibly rich while 85 million Americans go uninsured or underinsured".[173] Massachusetts Democratic Senator Elizabeth Warren stated, "The visceral response from people across this country who feel cheated, ripped off, and threatened by the vile practices of their insurance companies should be a warning to everyone in the health care system. Violence is never the answer, but people can be pushed only so far."[174] New York Democratic Representative Alexandria Ocasio-Cortez said, "This is not to say that an act of violence is justified, but I think for anyone who is confused or shocked or appalled, they need to understand that people interpret and feel and experience denied claims as an act of violence against them."[175] Vermont senator Bernie Sanders condemned the killing, but said the public response showed that many people were angry at health insurance companies and their practices.[176] Oregon senator Ron Wyden commented that "I've long said violence, murder, are always unacceptable, always. But I think that there is a context, you know, here that is hugely important".[177]
Opinion polling
An Emerson College poll surveyed 1,000 American registered voters about the Thompson killing between December 11 and 13, 2024. The poll found that a majority (68%) of voters viewed the actions of the suspected killer as unacceptable. Among young voters aged 18–29, 41% found the killing "acceptable or somewhat acceptable", while 40% in the same age group did not.[178][179]
NORC at the University of Chicago conducted a poll of 1,001 American adults between December 12 to 16. When asked about the factors contributing to Thompson's death, 78 percent of respondents said the killer has "a great deal or a moderate amount of responsibility". A majority of respondents said that denials for health care coverage by insurance companies (69%) or the profits made by health insurance companies (67%) bore a "great deal or moderate amount" of responsibility for Thompson's death. A majority of respondents (53%) also said "wealth or income inequality in general" shared a "great deal or moderate amount" of responsibility for the killing. Young Americans were the age group least likely to say that the killer was responsible for the killing.[180][181]
An Economist/YouGov poll conducted from December 15 to 17 surveying 1,553 U.S. adult citizens found that 43% of American citizens had a "somewhat unfavorable or very unfavorable" view of Mangione, while 21% had a "somewhat favorable or very favorable view of him." Mangione received the most support from citizens aged 18–29 and "very liberal" citizens. He was viewed least favorably by citizens aged 65 and older and "very conservative" citizens.[182]

The poll found that "61% of respondents said they have a strong or somewhat negative perception of Mangione", while 19% had a positive or somewhat positive view. Opinions on Mangione varied "dramatically" by age.[184] The poll also found that young Americans view Mangione "far more favorably" than they viewed Thompson and UnitedHealthcare.[185][186]
A poll of 6,000 U.S. adults was conducted by CloudResearch on December 19, utilizing AI. The poll found that 27% of respondents were sympathetic to Mangione, with 12% supporting the murder. Support for the murder was higher among those under 30 and the political left.[187]
Generation Lab conducted a poll of 1,026 U.S. college students between December 19 and 23. When asked about who they sympathized with more, 45% of respondents said the suspect, 17% said Thompson, and 37% said neither. Most respondents (81%) said they have an extremely or somewhat negative view of Thompson.[188]
USA Today/Suffolk University conducted a poll of over 1,000 registered voters between January 7 and 11. The poll found that almost two-thirds of respondents thought the killing was wrong and that the killer should be prosecuted. Most of the rest agreed that the killing was wrong, but that they understood the killer's anger.[189]

Notes
- ^ a b c The state of New York defines first- and second-degree murder differently than most states. Usually premeditated murder is first-degree; in New York it is second-degree, with first-degree being reserved for a premeditated murder with one of a list of aggravating factors.[190] The only possibly applicable one in this case is murder committed as an act of terrorism. See Murder in New York law.

An internal New York Police Department report obtained by The Times walks through parts of the three-page manifesto the suspect had at the time of his arrest and the potential for others to see him as "a martyr and an example to follow." The suspect "appeared to view the targeted killing of the company's highest-ranking representative as a symbolic takedown and a direct challenge to its alleged corruption and 'power games,' asserting in his note he is the 'first to face it with such brutal honesty,'" according to the intelligence analysis report drawn up by the Police Department's Intelligence and Counterterrorism Bureau.
