Luigi Mangione was charged with murder by NYC officials for the shock execution of UnitedHealthcare CEO Brian Thompson.

He was detained on Monday by police in Pennsylvania.

Mangione now faces three gun charges and forgery in New York.

He remains jailed in Pennsylvania on charges of possession of an unlicensed firearm, forgery and providing false identification to police.

Mangione was arrested in an Altoona McDonald's on Monday after cops 'immediately recognized' him as the suspect in the murder of UnitedHealthcare CEO Brian Thompson.

Luigi Mangione remains jailed in Pennsylvania but is expected to be extradited to New York where he faces a murder charge.

Initially, Mangione was charged with possession of an unlicensed firearm, forgery and providing false identification to police before Manhattan prosecutors added the murder charge, according to an online court docket.

It's unclear whether Mangione has an attorney who can comment on the allegations.

Asked at Monday's arraignment whether he needed a public defender, Mangione asked whether he could 'answer that at a future date.'

Mangione was arrested in Altoona, Pennsylvania, after the McDonald's customer recognized him and notified an employee, authorities said.

Altoona is about 233 miles west of New York City.

Luigi Mangione's former Hawaii roommate R.J. Martin told CNN’s Erin Burnett Monday night it is 'unfathomable' and he is 'beyond shocked' by the news of his arrest.

'He was a very thoughtful person. Communicated really well, was friendly, had good relationships with everyone. He was even, in some ways, a bit of a leader,' Martin said.

When I first interviewed him, before he moved in, I remember he said he had a back issue, and he was hoping to get stronger in Hawaii.'

Martin said Mangione told him he had surgery that left him with screws in his body and when he moved to Hawaii Mangione took a surfing lesson that left in in bed for a week.

'He sent me the X-rays,' Martin said. 'It looked heinous, with just giant screws going into his spine. After that, he called me once, I didn’t pick up.

'[Mangione] never once talked about guns, never once talked about violence. He was absolutely a not violent person, as far as I could tell.'

New York City Mayor Eric Adams called Altoona Police Office Tyler Frye who arrested suspected UnitedHealthcare CEO shooter Luigi Mangione on Monday.

Frye, who has only been on the job for about six months, said he 'recognized [Mangione] immediately' after he pulled down his face mask in the McDonald's.

Adams recorded his coversation thanking Frye for his service and posted it on X.

'We're very appreciative of the partnership between local police, state partners, and the NYPD. Together, we brought him into custody and took a dangerous individual off our streets,' Adams said.

HIs mother, Kathleen Mangione, made the report to the San Francisco Police Department on November 18, sources told the outlet.

Mangione's former high school classmate told the New York Times he and other peers were forwarded a message earlier this year because Mangione’s family was trying to track him down.

Cranston said the message claimed family members had not heard from Mangione for several months following a back surgery.

'Our family is shocked and devastated by Luigi’s arrest,' Mangione's cousin Republican Maryland Delegate Nino Mangione said in a social media post.

We offer our prayers to the family of Brian Thompson and we ask people to pray for all involved.'

UnitedHealthcare CEO shooting suspect Luigi Mangione appeared subdued as he wore a blue suicide prevention smock in his newly released booking photo.

The Pennsylvania Department of Corrections said he is being housed at the State Correctional Institution at Huntingdon.

The suspected gunman reportedly referenced UnitedHealthcare in the handwritten document found on him.

Luigi Mangione mentioned the $515.93 billion company in his manifesto noting the size of the company and how much money it makes, a senior law enforcement offical who saw the document told the New York Times.

In the 262-word handwritten manifesto, Mangione said as UnitedHealthcare’s market capitalization has grown, American life expectancy has not.

The document condemned companies that 'continue to abuse our country for immense profit because the American public has allowed them to get away with it.

He reportedly wrote that acted alone and that he was self-funded.

'To save you a lengthy investigation, I state plainly that I wasn’t working with anyone,' Mangione said.

'These parasites had it coming. I do apologize for any strife and trauma, but it had to be done.'

Suspected UnitedHealthcare CEO shooter has been in the Keystone State for 'several days' following the deadly attack, according to police.

Pennsylvania State Police Lt. Col. George Bivens said police are working to piece together where the suspect went following Brian Thompson's assassination.

'We know that he has been in Pennsylvania for several days, so part of that investigation will also focus on trying to retrace his steps,' Bivens said.

Officer Tyler Frye, who has only been on the job for about six months, was greeted with a round of applause from his fellow officers outside of the Pennsylvania court house, reported the New York Times.

Frye and his partner said they 'recognized [Mangione] immediately' after he pulled down his face mask in the McDonald's.

'We didn’t even think twice about it, we knew that was our guy,' Frye said.

'It feels good to get a guy like that off the street, especially starting my career this way, it feels great.'

Pennsylvania Gov. Josh Shapiro credited the arrest of Luigi Mangione to rookie police officer Tyler Frye.

'I want to say a special thanks to officer Tyler Frye of the Altoona Police Department,' Shapiro said.

'Officer Frye is about six months into his time serving his fellow people here in Pennsylvania and he acted swiftly, he acted with smarts and he acted with calm.'

According to court documents, Mangione was found with a black 3D-printed pistol and a black silencer in his backpack.

Gov. Josh Shapiro said suspected UnitedHealthcare CEO shooter Luigi Mangione is 'no hero' following his court appearence.

'In America, we do not kill people in cold blood to resolve policy differences or express a viewpoint,' Shapiro said.

'He is no hero. The real hero in this story is the person who called 911 at McDonald's this morning.'

Luigi Mangione's X account is back up after it was briefly deleted as YouTube removed channels belonging to the suspected killer.

Elon Musk addressed the removal of Mangione's X account stating, 'his happened without my knowledge. Looking into it.'

YouTube removed three channels belonging to Mangione, as well as a channel that was altered Monday to look as if it belonged to him, Jack Malon, Google policy communications manager, confirmed to CNN.

Luigi Mangione provide police with a fake ID when they approached him in McDonald's on Monday, but quickly admitted his mistake.

Mangione was wearing a medical mask and looking at his laptop when officers approached him, according to court documents.

Police said they asked him to pull down the mask and 'immediately recognized him as the suspect from New York City.'

The suspected UnitedHealthcare CEO shooter provided cops with a fake ID bearing the name Mark Rosario.

After police found no record for Rosario they advised him if he lied about his identity that he would get arrested.

Finally he stated his real name and when police asked why he lied, Mangione replied 'I clearly shouldn't have.'

Luigi Mangione, 26, started shaking when approached by police in an Altoona, Pennslyvania McDonald's and asked if had been to New York, court documents revealed.

The suspected UnitedHealthcare CEO shooter provided cops with a fake ID bearing the name Mark Rosario.

While police ran the information through the dispatch center they asked Mangione if he had been to New York recently.

Police said, '[Mangione] became quiet and started to shake.'

He has been charged with forgery, carrying a gun without a license, tampering with records or identification, carrying 'instruments of a crime' and presenting false Identification to law enforcement.

Mangione did not enter a plea and was denied bail. His next court appearence is scheduled for December 23 at 9 a.m. ET at the Blair County Courthouse.

The suspect in last week's high-profile shooting of United Healthcare CEO Brian Thompson is related to a Republican politician.

A member of the House of Delegates since 2019, the elder Mangione has yet to address the arrest.

Mangione, 26, looked stern in his mugshot as he wore a black jacket and scarf in the photo following his arrest at an Altoona, Pennslyvania McDonald's.

Luigi Mangione, 26, appeared somber as he arrived at the Blair County Court House in Hollidaysburg, Pennsylvania on Monday.

The suspected shooter wore a long sleeve shirt as police escorted him out of the vehicle.

He was led out of the car by two officers with both his hands behind his back.

Those close with Luigi Mangione reportedly shared messages on X letting them know they were worried about him in the days leading up to UnitedHealthCare CEO Brian Thompson's assasination.

Posts viewed by The Daily Beast showed loved ones tried to reach out and connect with him before the killing.

'Thinking of you and prayers everyday in your name,' wrote user @Collin30923201P on November 25. 'Know you are missed and loved.'

The day prior, the suspected shooter is believed to have arrived in New York City and checked into a hostel on November 24.

'@PepMangione Hey, are you ok? Nobody has heard from you in months, and apparently your family is looking for you,' wrote X user @TheRealMandusa on October 30.

The suspected killer of UnitedHealthCare CEO Brian Thompson is set to appear in a Pennsylvania court on Monday evening.

Mangione, 26, is scheduled for a 6 p.m. ET preliminary arraignment at the Blair County Court House in Hollidaysburg, a spokesperson for the Pennsylvania State Courts told Fox News.

He is reportedly refusing to talk to police.

'Suspect didn't say a word. He refused to talk,' a law enforcement source told the news outlet.

Several fake Facebook accounts impersonating Luigi Mangione have been created since his arrest.

An unconfirmed YouTube account using the alleged shooters name and photo posted an eerie message hours after his arrest.

'If you see this, I'm already under arrest,' the silent 84 second clip is captioned.

The video displayed a 60 second countdown then jumped to screen that said,'Soon... Dec 11th.'

'All is scheduled, be patient. Bye for now,' stated the final message displayed on the screen.

The suspected killer of UnitedHealthCare CEO Brian Thompson is the heir to a holiday resort fortune created by his grandparents - and the brother of a top doctor.

Luigi Mangione, 26, comes from a powerful Maryland family centered around the late patriarch Nicholas Mangiano, a first-generation American who built a real estate empire in the state that included country clubs and media.

Nicholas, who died in 2008 aged 83 after suffering a stroke, was the owner of Turf Valley Resort and Hayfields Country Club, as well as the radio station at the WCBM-AM.

Nicholas was born in Baltimore's Little Italy to a poor family but worked his way up from nothing. He also founded the nursing home Lorien Health Services. Luigi volunteered at his grandpa's nursing home in 2014, according to his LinkedIn.

Nicholas had 10 children, including Luigi's father Louis, and was married to his wife Mary until his death. The couple lived in a $1.9 million mansion situated on their country club, with Mary dying in 2013.

Details from the suspected shooter's social media reveal that he was obsessed with the back pain - and had read two books on the matter.

'Crooked: Outwitting the Back Pain Industry and Getting on the Road to Recovery' by Cathryn Ramin, and 'Back Mechanic' By Dr Stuart McGill are two books that were on Mangione's Goodreads account.

On his X account, his cover photo included an image of a Pokemon, a spinal surgery X-ray, and a photo of himself on a hike.

It is unclear if he ever underwent surgery for back pain.

The suspect in the shooting of CEO Brian Thompson proudly showed off his education on his LinkedIn page.

Mangione showed he had two degrees from the University of Pennsylvania, and that he graduated from his high school with the highest cumulative four-year GPA.

NYPD detectives have arrived in Pennsylvania, where Mangione was arrested.

He will now be questioned in relation to the death of Brian Thompson.

The suspect would need to be extradited to New York to face any charges there.

In an unearthed Facebook post from six years ago, a 'Penn Crush' was written about Luigi Mangione.

The page was set up for anonymous college kids to write love notes to their crushes.

The post read: 'Luigi Mangione. Hot damn. Are you single? You make us engineers have hope!'

Mangione, who graduated from UPenn in 2020, responded: 'Despite all my best efforts... yup still single.'

Mangione often flexed his private school and Ivy League education on X.

In one interaction, he added to a debate about what is a worse crime - homicide or rape.

The suspect said that the poll results showed that people think homicide has worse consequences, but rape is a result of worse virtues.

While not giving his own opinion, Mangione's conclusion seems to show that homicide can be virtuous if the action is utilitarian - as in, being an action that maximizes happiness and well-being for the greatest number of people.

Luigi Mangione, a 26-year-old Ivy League grad from Maryland, posted at least half a dozen quotes from the homegrown terrorist, who plagued the nation for nearly 20 years with his homemade bombs.

'Imagine a society that subjects people to conditions that make them terribly unhappy then gives them the drugs to take away their unhappiness,' read one excerpt from a Kaczynski quote on Mangione's Goodreads page.

He also included quotes ranging from Socrates and Marcus Aurelius to Aldous Huxley and Dr. Seuss.

'They say a healthy person has a thousand wishes but a sick person has only one wish - to get well,' read another quote on his Goodreads page attributed to bestselling fitness author Joe De Sena from The Spartan Way: Eat Better. Train Better. Think Better. Be Better.

Some of the other Kaczynski quotes included, 'The conservatives are fools: They whine about the decay of traditional values, yet they enthusiastically support technological progress and economic growth.'

New York Police cops, including Deputy Commissioner Kaz Daughtry, arrive at Altoona Police Department following the arrest of Luigi Mangione.

Mangione often posted his ideas of self-improvement on social media - and his X account was littered with him responding to big thinkers.

He interacted with people like neuroscientist Andrew Huberman and writer Tim Urban.

Watch his valedictorian speech below:

Adams told a Monday afternoon news conference he thinks people wearing face masks should pull them down and show their faces when entering shops and taxis.

Mangione was wearing a Covid-style face covering in many of the surveillance images police used to track him down.

This obscuration proved a major roadblock in their search, Adams said.

'Last year or earlier this year we called to say, when you go into a business or establishment, ask people to temporarily remove their mask,' he said.

'We can close these cases in hours if everybody would cooperate.'

It was the image of Mangione briefly seen without his face covering at a Starbucks which led to his identification by a McDonald's employee in another state.

Police recovered a fake New Jersey driving license from Mangione when they detained him in Altoona on Monday.

Mangione had been using multiple fake IDs, including the below license issued in June, where he is posing as 'Mark Rosario'.

Gilman School in Baltimore, where Luigi Mangione graduated as valedictorian in 2016, has sent an email to alumni in the wake of his arrest.

'This is deeply distressing news on top of an already awful situation,' school head Henry P.A. Smyth wrote, per the New York Times.

'Our hearts go out to everyone affected.'

Tuition at the private high school currently costs almost $40,000 a year.

The suspect had been working as a data engineer at TrueCar Inc for the past four years, according to his LinkedIn profile.

TrueCar is a car pricing and digital retailing website based in Santa Monica, California.

The LinkedIn profile also listed his college education - including an Engineering BA and MA both from UPenn.

The health insurance company released a statement in response to Mangione's arrest.

'Our hope is that today’s apprehension brings some relief to Brian’s family, friends, colleagues and the many others affected by this unspeakable tragedy,' the firm said.

'We thank law enforcement and will continue to work with them on this investigation. We ask that everyone respect the family’s privacy as they mourn.'

In the manifesto, Luigi Mangione said he acted alone and that he was self-funded.

According to CNN, the alleged CEO shooter's words suggested violence was the answer.

Some details from Luigi Mangione's manifesto, which was found on him when he was arrested, have been published by CNN.

The document, which spanned two pages, read: 'These parasites had it coming.

'I do apologize for any strife and trauma, but it had to be done.'

The document was two pages long, and is currently being investigated by law enforcement.

The suspected CEO shooter was interested in strange, anti-establishment literature, according to what seems to be his online Goodreads account.

He left a positive review for the manifesto of domestic terrorist Theodore Kaczynski, the infamous 'Unabomber', praising him as a 'political revolutionary'.

In January this year, the account left a four-star review of the book, called Industrial Society and Its Future.

'Clearly written by a mathematics prodigy. Reads like a series of lemmas on the question of 21st century quality of life,' the review reads.

'It’s easy to quickly and thoughtless write this off as the manifesto of a lunatic, in order to avoid facing some of the uncomfortable problems it identifies,' it continues.

'But it’s simply impossible to ignore how prescient many of his predictions about modern society turned out.'

Luigi Mangione was arrested on firearm charges on Monday - and has been named as a person of interest in the death of Brian Thompson.

Apart from his intellectual, Ivy League-educated background, questions have been raised about the suspect's history with the medical community.

As of Monday afternoon, he has not been charged in the death of Brian Thompson.

Mangione allegedly has an ailing relative who was mistreated by the health system.

He also lost his grandmother in 2013, and his grandfather in 2017.

The 26-year-old also used to work in an assisted-living facility for the elderly while he was studying at his $40,000-a-year high school in Maryland.

The handwritten manifesto found on Mangione indicated that he 'has some ill will toward corporate America,' NYPD's Joseph Kenny said.

He added that there was no indication that anyone else would be in danger.

Joseph Kenny, the chief of detectives at NYPD has said the ghost gun found on Mangione may have been created using a 3D printer.

He added that it can fire a nine-millimeter bullet.

Luigi Mangione is originally from Towson, Maryland, and is an anti-capitalist former Ivy League student, according to the New York Post.
