UnitedHealth Group

Brian Thompson was the CEO of UnitedHealthcare. He first joined the company in 2004 and held several positions before taking on the role of CEO in 2021.

Prior to working at UnitedHealthcare, Thompson was employed at PwC, according to his LinkedIn profile. He also graduated with honors from the University of Iowa with a Bachelor's degree in business administration as an accounting major in May 1997, the school's public relations manager Steve Schmadeke told NBC News.

Thompson, who lived in Minnesota, was married to Paulette Thompson—though according to public records viewed by E! News, they had been living in separate homes—and was the father of two sons.He was shot and killed in New York on Dec. 4, 2024. Thompson was 50 years old.

Patrol officers from the New York City Police Department’s Midtown North Precinct responded to a 911 call at 6:46 a.m. on Dec. 4, 2024 regarding a person who was shot in front of the New York Hilton Midtown hotel, NYPD Chief of Detectives Joseph Kenny said in a media briefing later that morning.

Kenny noted officers arrived at the scene at 6:48 a.m. and found gunshot wounds on Thompson’s back and leg. The chief detective said Emergency Medical Services transported Thompson several blocks to Mount Sinai West, where the CEO was pronounced dead at 7:12 a.m.

“The victim was in New York City to speak at an investor conference," NYPD commissioner Jessica Tisch said during the media briefing. "It appears the suspect was lying in wait for several minutes. And as the victim was walking to the conference hotel, the suspect approached from behind and fired several rounds, striking the victim at least once in the back and at least once in the right calf. Many people passed the suspect, but he appeared to wait for his intended target.”

Tisch said the shooting appeared to be a “pre-meditated, pre-planned, targeted attack” and not a random act of violence.

“The full investigative efforts of the New York City Police Department are well underway,” she noted, “and we will not rest until we identify and apprehend the shooter in this case.”

According to Kenny, the shooter headed to the New York Hilton Midtown on foot and arrived outside the hotel five minutes before Thompson’s arrival.

In a video, Kenny continued, Thompson was seen walking alone towards the Hilton at 6:44 a.m. after exiting his separate, nearby hotel apparently for a UnitedHealth Group investors conference that was scheduled to begin at 8 a.m. that day.

The chief detective added the shooter—who ignored "numerous other pedestrians"—approached Thompson from behind, shot him, walked towards him and continued shooting.

Kenny said the gunman then fled on foot before getting on an ebike, and the shooter was seen riding into Central Park at Center Drive at 6:48 a.m.

Kenny said three live nine-millimeter rounds and three discharged shell casings were recovered during the investigation. During a Dec. 6 press briefing, Kenny said the words “depose,” “delay” and “deny” were written on the shell casing in marker.

However, he’s noted the motive for the killing has yet to be confirmed.

During the Dec. 6 press briefing, Kenny said investigators have footage of the shooter arriving at Port Authority in New York the night of Nov. 24.

“We believe that that bus originated in Atlanta,” Kenny continued. “It has several stops along the way, so we’re not sure where he got on the bus.”

After the shooter arrived at Port Authority, Kenny continued, the gunman took a cab to the vicinity of the Hilton hotel, where he was for about half an hour before traveling by cab to an Upper West Side hostel.

On the morning of the shooting, Kenny added, the gunman left the hostel at 5:30 a.m. and arrived at the Hilton hotel at 5:41 a.m. Kenny said the gunman continued to walk in the vicinity of the hotel before then going to a nearby Starbucks, where he purchased a bottled water and a snack. He then returned to the hotel, and the shooting occurred at 6:44 a.m.

Immediately after, the gunman fled the scene. Kenny said the shooter was seen entering Central Park at 60th St. and Center Drive at 6:48 a.m. and exiting the park through W. 77th St. and Central Park West at 6:56 a.m. At 7:00 a.m., Kenny added, the gunman was spotted on W. 86^th St without the bike. And four minutes later, the chief detective continued, the shooter got in a cab at 86^th St. and Amsterdam Avenue. Kenny said the gunman was then seen in the vicinity of the George Washington Bridge at 7:30 a.m.

Kenny told CNN on Dec. 6 investigators thought the shooter left NYC after he was seen at Port Authority.

NYPD

During the Dec. 4 briefing, Kenny said the shooter appeared to be a "light-skin male" who wore "a light brown or cream-colored jacket, a black face mask, black and white sneakers and a very distinctive gray backpack."

Over the next few days, the NYPD released a series of photos of the individual they were looking for with the person's face was covered with a mask in many of the pictures.

A senior law enforcement official told NBC News Dec. 5 the photos with the lowered face mask came from surveillance video at an Upper West Side hostel, and two separate law enforcement officials noted to the outlet investigators were trying to determine if the individual used a fake ID and cash for a hostel room.

As for what led the individual to lower the face mask?

"Apparently, there was an interaction while he was checking in, making casual conversation," Kenny said at the Dec. 6 briefing. "At some point, he pulled his mask down and smiled at the clerk."

Kenny has also said a cellphone was found in an alley where the shooter fled before heading to the ebike, but it's unclear if it belonged to the gunman. Two law enforcement sources told NBC News a backpack was also found in Central Park.

Kenny said investigators are "looking at everything"—including Thompson's social media and interviews with employees and family—that could help the case. They're also working with Minnesota and Atlanta law enforcement.

Pennsylvania’s Altoona Police Department arrested Luigi Mangione on firearm charges Dec. 9.  According to a criminal docket obtained by NBC News, these include two felony charges—one of forgery and one of firearms not to be carried without a license—as well as three misdemeanors: tampering with records or identification, possessing instruments of a crime and providing false identification to law enforcement.

NYPD commissioner Tisch said a McDonald’s employee recognized Mangione and that the Altoona police were then called. When asked if he had been to New York recently, Mangione "became quiet and started to shake," police said per NBC News.

Tisch also called Mangione a "person of interest" in Thompson's murder and spoke about the efforts to find him, with her thanking law enforcement partners and the public.

"For just over five days, our NYPD investigators combed through thousands of hours of video, followed up on hundreds of tips, and processed every bit of forensic evidence: DNA, finger prints, IP addresses and so much more to tighten the net," she said. "We deployed drones, canine units, and scuba divers. We leveraged the domain awareness system, Argus cameras and conducted aviation canvases, and our detectives also went door to door interviewing potential witnesses and doing the good old fashioned police work that our investigators are famous for. This combination of old school detective work and new age technology is what led to this result today."

In addition to "acting suspiciously," Tisch added, Mangione was "carrying multiple fraudulent IDs as well as a U.S. passport."

“Upon further investigation, officers recovered a firearm on his person as well as a suppressor, both consistent with the weapon used in the murder," she continued in the Dec. 9 briefing, per a video shared by NBC News. "They also recovered clothing, including a mask consistent with those worn by our wanted individual."

Tisch added officers also recovered a “fraudulent New Jersey ID” that matched the one the individual used to check into the New York hostel prior to the shooting.

"Additionally,” she continued, “officers recovered a hand-written document that speaks to both his motivation and mindset.”

NBC News

On Dec. 9, Manhattan prosecutors filed a murder charge against Mangione, according to court documents obtained by NBC News. The 26-year-old is also facing three counts of criminal possession of a weapon (two in the second-degree for loaded firearm and one in the third degree such as for a silencer) and one count of possessing a forged instrument.

He has yet to enter a plea for any charges.

According to NBC News, citing the NYPD, Mangione had three pages of writings on him that totaled less than 300 words when he was taken into custody. Three senior law enforcement officials told the outlet these writings read, in part, "Frankly these parasites had it coming."

In the writings, the officials continued, Mangione said he acted alone. However, the officials told NBC News they haven't ruled out other actors at this time.

“To the Feds, I’ll keep this short, because I do respect what you do for our country," Mangione's writings read, officials told NBC News. "To save you a lengthy investigation, I state plainly that I wasn’t working with anyone.”

Officials said Mangione also added, "I do apologize for any strife or traumas but it had to be done.”

However, Tisch noted Mangione's motive has yet to be confirmed.

"I think when we look at the manifesto, or that three-page written document that was recovered, you see anti-corporatist sentiment, a lot of issues with the healthcare industry," she said in a Dec. 10 Today interview. "But as to particular specific motive, that will come out as this investigation continues to unfold over the next weeks and months."

Mangione attended a hearing at the Blair County Courthouse in Hollidaysburg, Pennsylvania on Dec. 10. As he arrived, NBC News reported, he yelled out to families, "It’s completely out of touch and an insult to the intelligence of the American people."

Per the outlet, Mangione did not waive extradition to New York and was denied bail. As a result, he will remain in Pennsylvania's SCI Huntingdon prison.

His lawyer Thomas Dickey told reporters that Mangione will plead not guilty in Pennsylvania and will likely do the same in New York.

"I haven’t seen any evidence that says he’s the shooter,” he said, per NBC News. “Remember, and this is not just a small thing: A fundamental concept of American justice is the presumption of innocence, and until you’re proven guilty beyond a reasonable doubt."

Mangione is a suspect in the murder of Brian Thompson and is facing several other charges in both Pennsylvania and New York, including forgery and criminal possession of a weapon.

He's an Ivy League graduate, having received a Bachelor of Science in engineering in 2020 and a Masters of Science in engineering at the University of Pennsylvania, the school confirmed to NBC News.

NYPD Chief of Detectives Kenny shared additional details on Mangione's upbringing, saying he was born and raised in Maryland. His most recent address is listed as Honolulu but he also has connections to San Francisco, Kenny told NBC News.

After Mangione's arrest, his family released a statement on X.

"Unfortunately, we cannot comment on news reports regarding Luigi Mangione," they said in the Dec. 9 post. "We only know what we have read in the media. 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. We are devastated by this news."

After learning of the shooting, Thompson’s family mourned his passing.

“We are shattered to hear about the senseless killing of our beloved Brian,” a family statement obtained by NBC affiliate KARE in Minneapolis on Dec. 5 read. “Brian was an incredibly loving, generous, talented man who truly lived life to the fullest and touched so many lives. Most importantly, Brian was an incredibly loving father to our two sons and will be greatly missed. We appreciate your condolences and request complete privacy as our family moves through this difficult time.”

Thompson’s wife Paulette also recalled how her husband had received threats prior to his death.

"Yes, there had been some threats," she told NBC News Dec. 5. "Basically, I don’t know, a lack of coverage? I don’t know details. I just know that he said there were some people that had been threatening him."

UnitedHealth Group, the parent company of UnitedHealthcare, also expressed how it was "deeply saddened and shocked at the passing of our dear friend" Thompson, flying its flags at half-mast at corporate headquarters in Minnesota.

"Brian was a highly respected colleague and friend to all who worked with him," a Dec. 4 statement from the organization read. "We are working closely with the New York Police Department and ask for your patience and understanding during this difficult time. Our hearts go out to Brian’s family and all who were close to him.”

And while the company noted "our hearts are broken," it shared in a Dec. 5 statement that it has also "been touched by the huge outpouring of kindness and support in the hours since this horrific crime took place."

"So many patients, consumers, health care professionals, associations, government officials and other caring people have taken time out of their day to reach out," the message read. "We are thankful, even as we grieve. Our priorities are, first and foremost, supporting Brian’s family; ensuring the safety of our employees; and working with law enforcement to bring the perpetrator to justice. We, at UnitedHealth Group, will continue to be there for those who depend upon us for their health care. We ask that everyone respect the family’s privacy as they mourn the loss of their husband, father, brother and friend."

However, there's also been public criticism about UnitedHealthcare, Thompson and America's healthcare system overall.

This has included online conversations about insurance companies' claim denial rates as well as a look at accusations against Thompson.

For instance, in a class-action lawsuit filed by the City of Hollywood Firefighters' Pension Fund in May 2024 and obtained by NBC News, Thompson was accused of selling more than $15 million of his personal UnitedHealth shares after allegedly learning of an investigation of the company by the U.S. Department of Justice before the public did. When asked about the trades allegedly made by Thompson and other executives, a UnitedHealth spokesperson told Bloomberg in April 2024 "these directors and officers followed our protocols and received approval from the company."

The lawsuit, per the BBC, remains active.

And while a motive for the shooting hasn't been revealed, many outlets have noted the words “depose,” “delay” and “deny” on the shell casings are similar to the title of the 2010 book Delay Deny Defend: Why Insurance Companies Don't Pay Claims and What You Can Do About It.

Pennsylvania Governor Josh Shapiro slammed "deeply disturbing" online reactions to the killing: "In America," he said at a Dec. 9 press conference, per NBC News' video, "we do not kill people in cold blood to resolve policy differences or express a viewpoint."
