The man charged with murder in the killing of the CEO of UnitedHealthcare made it clear he wasn’t going to make things easy on authorities, shouting unintelligibly and writhing in the grip of sheriff’s deputies as he was led into court and then objecting to being brought to New York to face trial.

The displays of resistance on Tuesday (December 10, 2024) weren’t expected to significantly delay legal proceedings for Luigi Nicholas Mangione, who was charged in last week’s Manhattan killing of Brian Thompson, the leader of the United States’ largest medical insurance company. Little new information has come out about possible motivation, though writings found in Mr. Mangione’s possession hinted at a vague hatred of corporate greed.

In his first public words since he was arrested at a McDonald’s in Pennsylvania after a five-day search, the 26-year-old Ivy League graduate from a prominent Maryland real estate family emerged from a patrol car shouting about an “insult to the intelligence of the American people” while deputies pushed him inside a Courthouse.

A law enforcement bulletin obtained by The Associated Press (AP) said that at the time of his arrest, Mr. Mangione was carrying a handwritten document expressing anger with what he called “parasitic” health insurance companies and a disdain for corporate greed and power. He wrote that the U.S. has the most expensive healthcare system in the world and that profits of major corporations continue to rise while “our life expectancy” does not, according to the bulletin.

Mr. Mangione remained jailed in Pennsylvania, where he was initially charged with possession of an unlicensed firearm, forgery, and providing false identification to police.

Manhattan prosecutors were beginning to take steps to bring Mr. Mangione to New York, but at a brief hearing Tuesday (Dec. 10), defence lawyer Thomas Dickey said his client will not waive extradition and instead wants a hearing on the issue. Mr. Mangione was denied bail after prosecutors said he was too dangerous to be released. He mostly stared straight ahead at the hearing, occasionally looking at papers, rocking in his chair or looking back at the gallery.

“You can’t rush to judgment in this case or any case,” Mr. Dickey said afterward. “He’s presumed innocent. Let’s not forget that.” Mr. Mangione was arrested in Altoona, Pennsylvania, after a McDonald’s customer recognised him and notified an employee, authorities said.

New York police officials have said Mr. Mangione was carrying a gun like the one used to kill Thompson and the same fake ID the suspected shooter had used to check into a New York hostel, along with a passport and other fraudulent IDs.

A law enforcement official who wasn’t authorised to discuss the investigation publicly and spoke with The AP on condition of anonymity said a three-page, handwritten document found with Mr. Mangione included a line in which he claimed to have acted alone.

“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,” the document said, according to the official.

Thompson, 50, was killed on December 4, 2024, as he walked alone to a Manhattan hotel for an investor conference. From surveillance video, New York investigators determined the shooter quickly fled the city, likely by bus.

Mr. Mangione was born into a life of country clubs and privilege. His grandfather was a self-made real estate developer and philanthropist.

“Our family is shocked and devastated by Luigi’s arrest,” Mr. Mangione’s family said in a statement posted on social media late Monday (Dec. 9) by his cousin, Maryland Del. Nino Mangione. “We offer our prayers to the family of Brian Thompson and we ask people to pray for all involved.”

From January to June 2022, Luigi Mangione lived at Surfbreak, a “co-living” space at the edge of touristy Waikiki in Honolulu. Josiah Ryan, a spokesperson for owner and founder R.J. Martin, said he was widely considered a “great guy,” though he had long dealt with severe back pain that interfered with many aspects of his life.

UnitedHealthcare CEO Brian Thompson was killed Wednesday (December 4, 2024) morning in what investigators suspect was a targeted shooting outside a Manhattan hotel where the health insurer was holding an investor conference.

The killing was a “brazen, targeted attack,” Jessica Tisch, the New York City police commissioner said. New York Governor Kathy Hochul called it a “horrific and targeted shooting.”

Mr. Thompson, 50, was set to speak at an investor meeting when he was gunned down around 6,45 a.m. outside the New York Hilton Midtown by a shooter who fled on foot and then took an e-bike into Central Park, according to the New York Police Department.

Mr. Thompson was taken to a hospital but could not be saved. Police were still searching for the shooter as of late morning and no arrests had been made. Though officials said the attack appeared to be targeted, they did not yet have a motive for the shooting.

Mayor Eric Adams said police were reviewing evidence from the scene, including video. “It seems to be clearly targeted by an individual and we will apprehend that individual,” Mr. Adams said.

UnitedHealthcare is the insurance arm of the health care giant UnitedHealth Group Inc. The Minnetonka, Minnesota-based company was scheduled to have its annual meeting with investors in New York City to update Wall Street on the company’s direction and expectations for the coming year, according to a company media advisory. An announcement was made to attendees Wednesday (December 4, 2024) morning that the conference was ending early.

The Hilton is in a bustling part of Manhattan, a short walk from tourist sites such as the Museum of Modern Art and Rockefeller Center, and often dense with tourists and office workers on weekday mornings. The popular Rockefeller Center Christmas Tree lighting is set to take place Wednesday (December 4, 2024) evening.

Part of the block where the shooting took place was cordoned off with police tape, with a large contingent of police officers at the scene. Many security cameras are nearby. Mr. Thompson had served as CEO for more than three years and had been with the company since 2004.

Minnesota Gov. Tim Walz tweeted that the state is “sending our prayers to Brian’s family and the UnitedHealthcare team.” “This is horrifying news and a terrible loss for the business and health care community in Minnesota,” the Democrat wrote.

UnitedHealthcare is the largest provider of Medicare Advantage plans in the U.S. and manages health insurance coverage for employers and state-and federally funded Medicaid programs.
