UnitedHealthcare CEO’s Murder Leads to Luigi Mangione’s Indictment, Terrorism Charges Filed

Luigi Mangione, the man suspected of assassinating UnitedHealthcare CEO Brian Thompson earlier this month, was indicted on multiple charges, including first- and second-degree murder, by a New York grand jury. Manhattan District Attorney Alvin Bragg announced the charges Tuesday, which include terrorism-related allegations tied to the December 4 killing.

Thompson, 49, was fatally shot from behind on a busy Manhattan street while heading to the Hilton hotel for his company’s Investor’s Conference. Surveillance footage captured the masked assassin calmly fleeing the scene on a bike. Authorities say Mangione meticulously planned the murder, arriving in New York City on November 24 with the express purpose of killing Thompson.

Using a fake New Jersey ID under the alias “Mark Rosario,” Mangione checked into a Manhattan hostel and surveilled his target for days. After the killing, he reportedly fled New York by bus.

When Mangione was arrested on December 9 at a McDonald’s in Altoona, Pennsylvania, police recovered:

• A homemade 9mm handgun with a suppressor.

• Two ammunition magazines.

• The same fake New Jersey ID.

Investigators believe the weapon was assembled using a 3D printer, falling under the category of so-called "ghost guns," which are untraceable by authorities.

District Attorney Bragg described the murder as “a well-planned, targeted act of terrorism” designed to “shock, intimidate, and instill fear.” Mangione is charged with:

• First-degree murder as a killing in furtherance of terrorism.

• Second-degree murder, including terrorism-related accusations.

• Multiple weapons and forgery charges.

The first-degree murder charge carries a maximum penalty of life in prison without parole.

Mangione, 34, has a complex personal history. His mother filed a missing persons report with San Francisco police weeks before the attack, telling authorities she feared her son could be responsible after seeing surveillance images but declined to confirm his identity.

Authorities also uncovered a disturbing notebook allegedly belonging to Mangione, which detailed plans to target Thompson at what the writer described as “the annual parasitic bean-counter convention.” The entry read: “It’s targeted, precise, and doesn’t risk innocents.”

NYPD Commissioner Jessica Tisch condemned efforts by some to lionize Mangione’s actions, stating, “This was a senseless act of violence... Any attempt to rationalize this is vile, reckless, and offensive to our deeply held principles of justice.” Tisch and Bragg also vowed to crack down on ghost guns, which are increasingly tied to violent crimes.

Mangione is fighting extradition to New York. If he continues to resist, Governor Kathy Hochul will need to submit a formal “governor’s warrant” to Pennsylvania Governor Josh Shapiro to secure his transfer.

With its meticulous planning and shocking execution, this case has drawn national attention. It serves as a chilling reminder of the dangers posed by untraceable weapons and politically motivated violence.
