• UnitedHealthcare CEO Brian Thompson was fatally shot in New York City on Wednesday, the police said.
• The NYPD said Thompson, 50, appeared to be killed in a targeted attack.
• Police on Monday arrested a "person of interest" identified as 26-year-old Luigi Mangione.

Police in Pennsylvania on Monday arrested a "person of interest" in connection to the fatal Midtown Manhattan shooting of UnitedHealthcare CEO Brian Thompson.

The 26-year-old man, identified as Luigi Mangione, was arrested in Altoona, Pennsylvania, and charged with local gun and forgery charges, New York Police Department officials said during a press conference.

Mangione was arraigned on Monday evening and charged on five counts, including two felonies: forgery, carrying a firearm without a license, tampering with records or identification, possessing instruments of crime, and false identification to law enforcement, according to a criminal complaint viewed by Business Insider. He was ordered held without bail.

Mangione was arrested after an employee at a McDonald's recognized him from the surveillance photos circulated by law enforcement and called the police. The complaint said Mangione was wearing a blue medical mask and looking at a laptop when Altoona police arrived.

Mangione had fake IDs, a US passport, and a gun and silencer "consistent with" the one thought to have been used by the gunman who killed Thompson, police said. The criminal complaint said the gun and silencer had been 3-D-printed.

NYPD officials said Mangione was also found with a three-page handwritten document that suggested "he has some ill will toward corporate America."

Mangione is expected to be extradited to New York to face additional charges, NYPD officials said.

The manhunt for Thompson's killer

The NYPD had released more than a half-dozen surveillance images of the man suspected to be the shooter in the December 4 attack in the hopes that tips from the public could help authorities track him down.

The latest photos of the man suspected of the shooting — which has been described by police as a targeted attack — included one showing him in the back of what appears to be a taxi, wearing a blue medical mask and a dark hood. Another image showed the man standing outside the vehicle's window wearing a mask, hood, and dark puffer jacket.

Moments after shooting Thompson dead in the heart of Manhattan Wednesday, police say the gunman fled the scene, first on foot and then on an electric bike, which he rode into Central Park. Police believe the shooter ultimately escaped New York City by bus.

Investigators believed the gunman caught a cab on Manhattan's Upper West Side and directed the driver to a bus station as he made his getaway following the shooting, Bloomberg reported.

Police officials told CNN they believed the man left New York City via the Port Authority's George Washington Bridge Bus Station in Washington Heights.

"We have video of him entering the Port Authority bus terminal. We don't have any video of him exiting, so we believe he may have gotten on a bus," NYPD Chief of Detectives Joseph Kenny said in a December 6 interview. "Those buses are interstate buses. That's why we believe he may have left New York City," Kenny said.

NYPD divers were seen over the weekend searching the waters in Central Park for any evidence in the shooting.

A law-enforcement source told CNN that investigators had found a backpack in Central Park that they believed belonged to the gunman. The backpack contained a Tommy Hilfiger jacket and Monopoly money, CNN reported, citing law-enforcement officials and sources.

It was not immediately clear if other items were found in the backpack.

Kenny said on December 6 that officials were investigating the possibility that the gunman may have used a veterinary gun, used on farms to euthanize large animals quietly, in the shooting, CNN reported.

A law-enforcement source previously told BI that the gun used by the shooter appeared to be equipped with a silencer, according to surveillance footage of the attack.

Most of the images that police have released of the man wanted in the shooting show him with a mask covering the bottom half of his face, except a set of two, which NYPD Commissioner Jessica Tisch called the "money shot," that showed the clearest images yet of the suspect unmasked.

"He's been traveling and walking around the streets of New York City largely in a mask, with his face covered. We had to go through lots of video evidence to get that one money shot with the mask down," Tisch told CNN in a December 6 interview.

Tisch said that police released the photos of the man not wearing a mask because they wanted a "wider audience to see the picture outside of New York City."

"We are right now processing a tremendous amount of evidence in this case," the NYPD commissioner told the news outlet, adding that authorities already have "lots of forensic evidence," including fingerprints and DNA evidence.

Police have called the killing of Thompson premeditated

Police have described Thompson's killing as "a brazen, targeted attack."

Thompson was set to speak at UnitedHealth Group's 8 a.m. investor conference on December 4 when a hooded gunman opened fire from behind, striking him at least once in the back and at least once in the right calf, the police said.

"Every indication is that this was a premeditated, pre-planned, targeted attack," Tisch told reporters at a press conference hours after the shooting.

"It appears the suspect was lying in wait for several minutes," Tisch added.

The NYPD offered a $10,000 reward for tips leading to the gunman's arrest, and the FBI said it was also offering a reward of up to $50,000 for information leading to the gunman's arrest and conviction.

Multiple reports said that authorities conducted forensic tests on a discarded cellphone, protein bar wrapper, and water bottle.

How the suspect arrived in New York is also becoming clearer.

Authorities believe he may have traveled to the city 10 days before the shooting on November 24 on a bus that originated in Atlanta and dropped him off at Manhattan's main bus depot, the Port Authority Bus Terminal. It was not yet clear where along the route he boarded the bus.

The Atlanta Police Department announced Friday that the NYPD contacted it and will provide assistance in the investigation as needed.

The unmasked images of the wanted man released by police were captured at a hostel on New York City's Upper West Side, a law enforcement official told CNN, when an employee asked the man to lower his face mask.

The Times, citing a senior law enforcement official, previously reported that the suspect in the shooting used a fake New Jersey ID to book a room at the hostel he was staying at in the days before the attack.

Retired NYPD homicide detective Salvatore Tudisco previously told BI that the photos showing the man's face were likely to speed up the manhunt.

Tudisco led the city's last big manhunt for a murdered CEO, Gokada founder Fahim Saleh, whose killer was captured in three days by traces on credit card, cellphone, and surveillance camera evidence.

"That's the best option — to send it across the country, and someone will know him," the ex-detective said of the latest images.

He added that a facial-recognition trace would be less of an option because the hostel surveillance images do not show the man's full face.

Investigators can still try to run the photo through state driver's license and arrest databases, Tudisco said. However, some states require a judge to issue a warrant before state driver's licenses can be used as evidence in an arrest and beyond.

Shooter was 'proficient in the use of firearms,' police said

Kenny said at the NYPD's press conference in the aftermath of the shooting that the gunman arrived on 6th Avenue about five minutes before Thompson. The shooter's weapon appeared to jam during the attack, he added.

"From watching the video, it does seem that he's proficient in the use of firearms, as he was able to clear the malfunctions pretty quickly," Kenny said.

Surveillance footage captured the incident, showing the gunman firing his weapon as Thompson, wearing a blue suit jacket, was walking several feet in front of him.

A law-enforcement source, who is not authorized to talk to the press, told Business Insider that the gun appeared to be equipped with a silencer. The source added that the gunman "definitely knew" where Thompson was going to be.

The police said officers found Thompson unconscious and unresponsive two minutes after the shooting. Emergency responders rushed him to Mount Sinai Hospital, where he was pronounced dead at 7:12 a.m.

Police have not identified a motive

The shooting occurred blocks from Midtown holiday tourism landmarks, including Radio City Music Hall and Rockefeller Center, whose Christmas tree lighting took place on December 4.

In the aftermath of the shooting, six evidence cups were visible on the taped-off section of the sidewalk where the attack occurred.

"That's covering the shell casings," an officer at the scene told BI, declining to give their name because they were not authorized to talk to the media.

UnitedHealth Group canceled its "investor day" conference shortly after reports of the shooting broke.

Investigators have not yet determined a motive for the killing.

Kenny said investigators were combing through Thompson's social media and interviewing employees and family members and would be talking to law enforcement in Minnesota, where Thompson lived and where UnitedHealth Group and UnitedHealthcare are based.

Thompson's wife, Paulette Thompson, previously told NBC News in an interview that her husband had been receiving threats.

"Basically, I don't know, a lack of coverage?" she said. "I don't know details. I just know that he said there were some people that had been threatening him."

The police department in his hometown of Maple Grove, Minnesota, told BI it hadn't been notified of any threats he might have received. Theresa Keehn, the Maple Grove police administrator, initially said Maple Grove had no record of calls for service to his house. Still, the department later said it had responded to a 2018 call from Paulette Thompson. An incident report said she had been walking to bed when she saw the front door deadbolt turn and grew afraid someone was inside the house. The police did not find anyone inside the home.

An unnamed senior law enforcement official told NBC News that shell cases found at the scene were inscribed with the words "deny," "defend," and "depose." BI has not independently confirmed the description of the evidence, and an NYPD spokesperson didn't return a request for comment.

Jay M. Feinman, an author and legal professor specializing in insurance law, torts, and contract law, wrote a similarly titled book "Delay Deny Defend: Why Insurance Companies Don't Pay Claims and What You Can Do About It."

The book is dubbed an exposé of insurance injustice and explains how people can be more careful when shopping for insurance policies and what to do when pursuing a disputed claim.

The NYPD said Thompson arrived in New York City on Monday and was staying at a hotel across the street from where he was shot.

Police in Maple Grove, Minnesota, told BI homes of Thompson and his wife in a suburb outside Minneapolis were targeted with fake bomb threats Wednesday evening, more than 13 hours after the shooting.

Thompson was remembered as a 'hardworking Midwest guy.'

Thompson spent 20 years at UnitedHealth Group and was CEO of UnitedHealthcare, the health-benefits unit, since April 2021.

While announcing his promotion, the company said Thompson would "drive continued growth across the global, employer, individual, specialty, and government benefits business while continuing the company's focus on ensuring access to high-quality, affordable healthcare."

Leaders in the healthcare industry shared their condolences in the hours after Thompson's death.

UnitedHealth's shares were broadly unchanged after the shooting. They've gained about 12% in the past 12 months, less than the 32% increase in the S&P 500, but outperforming competitors, including CVS Health, Humana, and Elevance Health. During its third-quarter results in October, it gave what UBS called a "more conservative than usual" outlook for fiscal 2025. Ahead of Wednesday's investor day, it gave more detailed guidance for next year, forecasting revenue of $450 billion to $455 billion and adjusted earnings of $29.50 to $30 a share. The company also suffered a ransomware attack that disrupted pharmacy deliveries earlier this year.

By the afternoon of the shooting, UnitedHealth Group had removed the names of its executives from its website, an archived version of its site shows. Some executives also appeared to have deleted their LinkedIn profiles, though it's unclear when.

Thompson had previously served as CEO of the group's government programs, running its programs for Medicare and Medicaid recipients.

Thompson's former brother-in-law, Bassel El-Kasaby, told Business Insider that Thompson was "a good guy, very successful and very humble — just a decent, hardworking Midwest guy."

"Whoever did this is a coward and a loser," El-Kasaby said.

Correction: December 4, 2024 — An earlier version of this story misstated Thompson's work history at United Health. He worked at the company for 20 years but was not an executive there for 20 years.

Update December 9, 2024: This story was updated with details on the arrest of a "person of interest" in the shooting.

• Sean "Diddy" Combs will spend Thanksgiving behind bars at a Brooklyn jail.
• A turkey roast, mashed potatoes, and a peanut butter and jelly sandwich will be served to detainees.
• "It's not top-grade food," a former federal inmate turned prison consultant told BI.

Sean "Diddy" Combs may be spending this Thanksgiving behind bars at a notorious Brooklyn jail, but at least he won't miss out on turkey.

A menu obtained by Business Insider through the Federal Bureau of Prisons shows that a turkey roast, a non-meat option of hot and sour tofu, mashed potatoes, mixed vegetables, cranberry sauce, gravy, dinner rolls, and assorted holiday pie will be served for lunch on Thursday at the Metropolitan Detention Center.

Combs has been locked up at the infamous federal facility since his September arrest and indictment on federal charges of racketeering conspiracy, sex trafficking, and transportation to engage in prostitution.

The wealthy hip-hop mogul has denied the charges against him and has made several unsuccessful attempts to be released on bail ahead of his criminal trial scheduled for May.

Thanksgiving Day jailhouse dinner of PB&J

Combs and the more than 1,000 other people housed at the facility — who include crypto fraudster Sam Bankman-Fried — will also be offered a Thanksgiving Day breakfast of fruit, cereal, pastries, and skim milk as well as a dinner option of a peanut butter and jelly sandwich, potato chips, whole wheat bread, and more fruit, according to the menu.

"It's not top-grade food," Sam Mangel, a former federal inmate turned prison consultant, told Business Insider. "It's not spoiled or rancid, but it's leftovers, or food very close to its expiration dates."

Mangel, who says he has worked with five people currently detained at the Brooklyn jail, including Bankman-Fried, told BI that the Thanksgiving turkey spread, will be served at 11 a.m. and will feature only sliced or "pressed" turkey meat for security reasons.

"A bone from a turkey leg can be fashioned into a knife," said Mangel. "At an MDC, or detention center, where there are all levels of security mixed together, they're not going to put turkey bones into an inmate's hands."

By 12:30 p.m. on Thanksgiving, detainees can expect to be handed a bag with a peanut butter and jelly sandwich inside for dinner later on, Mangel said.

"And then all the kitchen staff go home early," he said.

Commissary seasonings help with flavor

Combs and others at the jail will have to use plastic "sporks" and the same plain plastic dishes as any other day when chowing down on the Thanksgiving grub, Mangel said, adding that there will be no Turkey Day decor.

People detained there, the prison consultant said, often get creative with their meals, buying seasonings and cheese from the commissary to add some flavor to the meat.

"They'll make it into burritos, or nachos, or a wrap," said Mangel.

Combs is being held in the specialized housing unit of the jail, which is separate from the general population.

A source told BI in September that Bankman-Fried and Combs were bunking in the same dormitory. Bankman-Fried, the founder of the collapsed cryptocurrency exchange FTX, was sentenced to 25 years in prison earlier this year after a jury found him guilty of all seven counts of fraud and conspiracy. He is appealing his conviction.

Combs, Bankman-Fried, who had been on a vegan diet, and a small group of others being housed in the same jail unit will likely share their Thanksgiving meal together, Mangel said.

"When it comes to the holidays, you'd be surprised," Mangel told BI. "The guys do tend to become very sullen, and they commiserate with each other."

Attorneys for Combs and Bankman-Fried did not immediately respond to a request for comment by BI for this story.
