Luigi Mangione's Friends React to His Guilty Plea

On Friday, Luigi Mangione pleaded guilty in federal court to stalking and killing Brian Thompson, the CEO of United Healthcare. Thompson was shot and killed on a street in Manhattan in December 2024. Mangione entered his plea in front of a judge, while Thompson's family watched from the front row of the courtroom. The case has drawn attention across the country because many people see Mangione as a symbol of anger toward the American healthcare system. His friends and family had mostly stayed quiet since his arrest, but some are now speaking out.

Mangione has been held at the Metropolitan Detention Center, a federal jail in Brooklyn, New York. He has stayed in touch with some friends while locked up there. However, none of his friends or family were in the courtroom on Friday. Friends who spoke with Rolling Stone said they had no idea he was planning to plead guilty. His federal trial had been set to start in January 2027, and a state trial was scheduled to begin next month.

One of Mangione's friends, R.J. Martin, said Friday was 'deeply emotional.' Martin was Mangione's friend and former landlord in Hawaii, where Mangione lived after college. He described Mangione as a real person with close friends who care about him. Martin also said he believed the government had already decided Mangione was guilty before any trial took place. He said that made it hard to imagine Mangione ever getting a truly fair trial.

Other friends said they were surprised he chose to plead guilty instead of going to trial. Many said they were sad knowing their friend would likely spend much of his life in prison. They chose not to speak on the record, meaning they did not want their names published. A former friend who did computer programming with Mangione in high school said the guilty plea felt 'really weird.' He called it a stark shift from the person he used to know.

That former friend, who asked to be identified only as R.K., said Mangione never seemed like a political person growing up. R.K. said the situation shows how much radicalization has grown in the United States. He called the crime 'unacceptable and deeply sad.' But he also said he hopes people keep talking about problems with the American healthcare system. R.K. said he has seen those problems up close as someone from another country now living in the U.S.

When Mangione was first arrested in December 2024, students at his old high school in Baltimore were stunned. Gilman School is a well-known, highly regarded private school. Students were texting each other right away, asking things like 'Did you see the news?' and 'OMG, Luigi?!' One of his former classmates described Mangione as part of a group of students who were clearly heading to top colleges. But unlike the others, Mangione was also easy to talk to and had a cool, relaxed personality.

A former teacher at Gilman said Mangione always chased perfection because being smart was a big part of who he was. The teacher thought Mangione would grow up to work in science or build artificial intelligence programs. Friends who knew him in Hawaii described him as thoughtful, kind, and caring. After his arrest, his family went into a kind of lockdown, with his parents stopping their mail and his sisters deleting their social media accounts. Friends brought baked goods to the family's home to show support.

The Mangione family released a short statement in December 2024, saying they were 'shocked and devastated' by his arrest. They offered prayers to Brian Thompson's family and asked others to pray for everyone involved. That statement is the only thing the family has said publicly. During his guilty plea in court, Mangione himself spoke more publicly about the crime than he ever had before. He said that after years of dealing with serious back pain, he had struggled greatly with the health insurance system.

To learn where United Healthcare's conference would be held, Mangione emailed company leaders pretending to be an investor managing more than 50 billion dollars. He said that, unlike his past experiences with insurers, he got a reply within just one hour. After he finished speaking, Thompson's family released a statement saying they were grateful the legal system held the person responsible accountable. They also said they hoped the sentencing would reflect how serious the crime was.

Since his guilty plea, Mangione's supporters have expressed disappointment, sadness, and frustration online. Many said they had hoped he would go to trial so more attention would be paid to flaws in the U.S. healthcare system. His legal team has filed a motion to dismiss the state murder case, arguing that trying him again would be double jeopardy — meaning a person cannot be tried twice for the same crime. A New York judge is expected to rule on that motion in December. His federal sentencing hearing is set for December 18.
