28-year-old pleads guilty to federal stalking charges in executive's death
By Corinne Ramey and Anna Wilde Mathews
NEW YORK -- Luigi Mangione, whose coldblooded killing of an insurance executive on a Manhattan sidewalk rattled the nation and struck fear into Corporate America, pleaded guilty Friday to two federal stalking charges in the death of UnitedHealthcare leader Brian Thompson.
"On the morning of Dec. 4, 2024, I shot Mr. Thompson in Manhattan and he died," Mangione solemnly told the judge during a court hearing.
Mangione, wearing tan jail garb, told the judge that he spent years enduring severe pain, including a broken back, and witnessed others with similar experiences. He said that after learning of an investor conference, he emailed UnitedHealthcare, posing as an investor at a firm managing over $50 million in assets, to request information about it.
"Unlike my previous interactions with insurers, I received an immediate response within an hour," Mangione added. He said he made part of a gun using a 3-D printer and planned the killing.
U.S. District Judge Margaret Garnett said Mangione faces up to life in prison at his sentencing, which she set for December. Jamie McDonald, the U.S. attorney for the Southern District of New York, said after Friday's hearing that his office intended to seek the maximum penalty, saying Mangione committed the crime in order to "draw public attention to his dislike of certain businesses."
"No grievance, political belief or ideological cause can ever justify murder," McDonald said. "There can be no celebrity in assassination."
Thompson's family sat in the front row of the courtroom during the hearing. "Today's guilty plea marks an important step toward justice for Brian and for our family," the family said after the hearing.
The plea resolves one criminal case against Mangione but could upend or delay a separate state murder case that is scheduled to go to trial in early September. Though the state and federal charges aren't the same, his legal team contends that he can't be tried twice for the same offense, known as double jeopardy.
Mangione's legal team is seeking to dismiss the related state charges in light of Friday's plea. A spokesman for the Manhattan district attorney's office said it was prepared to litigate the issue.
Mangione has "accepted full responsibility for the death of Brian Thompson," a lawyer for Mangione, Karen Friedman Agnifilo, said. After becoming frustrated with the healthcare and insurance bureaucracy he had to navigate to receive treatment, Mangione "believed that the system had failed him and destroyed his life," she added.
The killing of Thompson, 50 years old, came as other top executives at UnitedHealth Group, parent of the largest U.S. health insurer, were getting ready for an investor presentation inside a Hilton hotel in Midtown Manhattan.
Prosecutors said that Mangione, 28, meticulously planned the killing for months, researching Thompson and tracking his whereabouts. At 6:45 a.m. local time that day, a masked Mangione shot Thompson outside the hotel on West 54th Street, prosecutors said. The conference began as scheduled at 8 a.m., only to be abruptly paused once news of the shooting broke.
The words, "deny," "delay," and "depose" were written on the side of some of the shell casings found at the scene, according to a complaint. They were quickly interpreted to be a variation of a rallying cry adopted by some people angry at the health-insurance industry.
Mangione fled uptown on an electric bicycle, then jumped into a cab that took him to the George Washington Bridge Bus Terminal. After a frantic dayslong manhunt, he was arrested at a McDonald's in Altoona, Pa.
Law-enforcement officials found inside his backpack a pistol equipped with a silencer and a notebook, authorities said. One entry said "the target is insurance" because "it checks every box," and another described an intent to "wack" an insurance chief executive at the investor conference, according to the federal complaint.
For UnitedHealth, where Thompson was a widely liked, affable executive who had risen through the ranks to lead its insurance unit, the loss left colleagues mourning at the same time they felt under attack. The company said Friday that it was "grateful to law enforcement for bringing Brian's murderer to justice."
The company ramped up security at its Minneapolis-area headquarters. Health-insurance leaders -- who had rarely seen themselves as high-profile targets for violence -- quickly hired bodyguards and canceled public appearances, while adding new layers of online threat assessment. The killing prompted companies across industries to reassess how they protect top executives.
It also helped unleash an online backlash against the health-insurance industry, particularly authorization requirements that can block patients' access to costly procedures and drugs. Mangione's supporters have shown up to court proceedings and funded billboard trucks. An online legal defense fund has raised $1.6 million, and a handwritten log of mail he has received in jail numbers 82 pages.
The industry has more recently sought to counter consumer angst through efforts that companies said would ease the process for approving treatments. Still, doctors and hospitals continue to complain that patients face friction and denials.
Mangione was born to a prominent Baltimore family. He attended the University of Pennsylvania, where he completed his bachelor's and master's degrees in computer science in four years.
He posted on social media about various health ailments, including irritable bowel syndrome and spondylolisthesis, a condition caused by a vertebra slipping out of place. He didn't have UnitedHealthcare insurance.
State prosecutors were first to charge Mangione, and federal prosecutors followed. Despite what seemed like a straightforward case with ample evidence, both prosecutions faced setbacks. A state judge threw out two terrorism-related charges, finding the allegations that Mangione killed Thompson for ideological reasons didn't meet the legal definition of terrorism.
Garnett had previously tossed two additional federal charges, taking the prospect of the death penalty off the table. Killing Thompson was clearly a crime of violence, but murder charges can rarely be brought under federal law and only under very specific circumstances that prosecutors hadn't met in the Mangione case, Garnett said.
