(NewsNation) — New York City Police have confirmed that Luigi Mangione is the only person of interest in the shooting of UnitedHealthcare CEO Brian Thompson.
He was arrested on firearms charges in Pennsylvania after questioning by authorities.
Luigi Mangione named person of interest
Mangione, 26, was found in possession of a fake New Jersey ID that matched the one used to check into the hostel, a firearm, suppressor and mask.
The weapon was described as a “ghost gun” or firearm without a serial number, which may have been 3D printed. Mangione also had a fraudulent New Jersey ID on him that matched the one used to check into a New York hostel prior to the shooting.
Mangione has no prior arrests and police said they do not believe he was attempting to flee the country.
Who is Luigi Mangione?
A person by the same name attended a private high school in Baltimore, Maryland, where they were a wrestler and graduated as valedictorian.
A spokesperson with the University of Pennsylvania confirmed that Mangiano attended and graduated with both bachelor’s and master’s degrees in engineering.
NewsNation affiliate WPIX confirmed that Mangione was employed as a head counselor for the Stanford Pre-Collegiate Studies program in 2019.
What is Luigi Mangione’s manifesto?
Investigators said a three-page handwritten document was found that they described as a manifesto.
While they said they don’t believe there are specific threats to others in the document, they described it as showing “ill will” toward corporate America.
Authorities say it gives insight into the mindset of motives in what they described as a “targeted” killing.
UnitedHealthcare CEO killing
Thompson was killed while walking to the company’s annual investor meeting. Police say they believe the attack was targeted and not a random act of violence.
The words “deny,” “depose” and “defend” were written on the shell casings found at the scene of the shooting, police sources said to NewsNation local affiliate WPIX.
The words appear to be a possible reference to a book titled “Delay, Deny, Defend,” which details the ways insurance companies use to reject requests for medical coverage deemed necessary by doctors.
UnitedHealthcare has the highest claim denial rate among insurance companies, rejecting 32% of submitted claims compared to the industry average of 16%.
Thompson, 50, was a father of two. He became CEO of UnitedHealthcare in 2021 and helped the company bring in $281 billion in profits in 2023. Between salary and other benefits, he was estimated to have more than $10 million in compensation last year.
Earlier this year, Thompson was sued by the Hollywood Firefighters’ Pension Fund for insider trading and fraud. Executives at United Healthcare were being investigated by the Department of Justice over allegedly running a monopoly and unfairly blocking out competitors.
The Department of Justice also launched an antitrust investigation into the UnitedHealthcare Group following a cyberattack on a subsidiary that handled healthcare payments. During the attack, many patients were forced to pay out of pocket for care and medications or were unable to get them because medical facilities were unable to process payments.
Search for the UnitedHealthcare CEO gunman
Police released surveillance photos of a person of interest they hoped to question, which showed an individual in a dark, hooded jacket with a backpack. The backpack was later located and found to contain Monopoly money.
Authorities said a McDonalds employee in Pennsylvania identified Mangione based on the photos and responding officers noticed he was acting suspiciously.
