Luigi Mangione to be arraigned Friday on federal charges in UnitedHealthcare CEO’s killing

Luigi Mangione, the 26-year-old accused of in New York City last December, is set to be arraigned on federal charges on Friday.

Mangione was indicted last week by a federal grand jury in Manhattan on four charges, including stalking and murder through the use of a firearm — the latter of which carries a maximum sentence of death.

Attorney General Pam Bondi said she intends to pursue the death penalty in the case.

“Mangione’s murder of Brian Thompson — an innocent man and father of two young children — was a premeditated, cold-blooded assassination that shocked America,” Bondi said in a statement earlier this month. “After careful consideration, I have directed federal prosecutors to seek the death penalty in this case as we carry out President Trump’s agenda to stop violent crime and Make America Safe Again.”

In late December, Mangione was indicted on 11 state charges in New York, including murder and terrorism. He pleaded not guilty.

Mangione is also facing state charges in Pennsylvania, where he was arrested following a weeklong manhunt. The charges there include possession of an unlicensed firearm, forgery and providing false identification to police. He was extradited to New York before entering a plea.

He is being held without bond at Metropolitan Detention Center Brooklyn, where Sean “Diddy” Combs and other high-profile defendants are also awaiting trial.

How authorities say the killing unfolded

Mangione is accused of fatally shooting Thompson on Dec. 4 outside the New York Hilton, where UnitedHealthcare’s parent company, UnitedHealth Group, was holding its annual Investor Conference.

According to the Manhattan District Attorney’s Office, Mangione arrived in New York City by bus on Nov. 24 and checked into a hostel on the Upper West Side under the name “Mark Rosario,” using a fake New Jersey ID.

On the morning of Dec. 4, investigators say, Mangione left the hostel around 5:30 a.m. ET and traveled to midtown near the Hilton hotel.

As Thompson was walking up to the hotel, Mangione took out a 9mm, 3D-printed ghost gun equipped with a 3D-printed suppressor and shot him once in the back and once in the leg.

Mangione fled the scene on a bicycle, setting off a five-day, nationwide manhunt.

He was arrested at a McDonald’s in Altoona, Pa., on Dec. 9 with the same fake New Jersey identification and the 3D-printed ghost gun, as well as a handwritten document that police said appeared to be a “manifesto.”

Police said Mangione’s fingerprints matched those collected by the NYPD on a water bottle and a KIND bar wrapper recovered near the scene of the shooting and on a cellphone found in an alley near the hotel.

The search for a motive

Authorities have yet to officially identify a motive in Thompson’s slaying.

According to the federal complaint unsealed in December, the FBI said that writings in the handwritten notebook Mangione had with him when he was arrested showed his “hostility towards the health insurance industry and wealthy executives in particular.” In one entry, Mangione wrote that “the target is insurance,” according to the FBI.

NYPD Chief of Detectives Joseph Kenny previously told reporters that there did not appear to be “any specific threats” mentioned in the manifesto, but “it does seem that he has some ill will toward corporate America.”

Mangione was not a customer of UnitedHealthcare, but police said as one of the largest corporations in America in the document.

“So that’s possibly why he targeted that company,” Kenny later said in an interview with NBC New York.

Police also reportedly recovered shell casings at the scene with – echoing the title of a 2010 book, “Delay, Deny, Defend,” that was highly critical of the insurance industry and describes a strategy of rejecting claims.

‘Free Luigi’ movement

The killing sparked a national conversation about the U.S. health care system — with people sharing stories about denied insurance claims — and made Mangione a hero in the eyes of some who share his apparent outrage over corporate greed.

At a procedural court hearing in lower Manhattan in February, braved frigid temperatures for hours to show their support for Mangione.

“I don’t condone murder, but what he did and its focus on UnitedHealthcare has really brought to life how our health care system is broken,” Shane Solger, one of the demonstrators outside the hearing, told Yahoo News. “I’m here because the way that our health care system is designed right now hurts people. This is kind of a protest of our health care system.”
