Luigi Mangione, the Baltimore County native who’s accused of killing UnitedHealthcare CEO Brian Thompson, captured national attention after his arrest last month.

Two broadcast documentaries — “Manhunt: Luigi Mangione and the CEO Murder – A Special Edition of 20/20” and “TMZ Investigates Luigi Mangione: The Mind of a Killer” — have already aired and more are in the works about the former Gilman School valedictorian.

Neither special, both of which can be found on Hulu, includes huge revelations. But if you’re unfamiliar with the details of the killing or Mangione’s well-connected family, they provide some illuminating context.

Thompson, 50, was shot and killed on Dec. 4, 2024, outside a hotel in Manhattan, where he had traveled for an annual investors meeting. His death led to a nationwide manhunt, with Mangione arrested at a McDonald’s in Altoona, Pennsylvania, on Dec. 9. The case sparked fierce debate, and Mangione has become a cause célèbre for some frustrated with the health care industry — inspiring internet memes and merchandise.

Mangione is facing multiple state and federal charges, including murder as an act of terrorism. Here are some key takeaways from the specials, including information that had not been previously reported.

Missing persons report

TMZ referenced a missing person report that Mangione’s mother called police in San Francisco after losing contact with him. TMZ said a detective in San Francisco reached out to his mother after initial suspect photos were released, before Mangione’s arrest.

When talking about the missing person report, the “20/20″ special said Mangione’s voicemail inbox was full, and that his family was unable to reach him via phone and text message.

Details from traveling

The TMZ special interviewed two men identified only as “Max” and “Paul” who said they met Mangione while traveling in Thailand last year. Mangione, they said, told them he went to a shooting range while others went to the beach. The two men said Mangione told them it was “expensive.”

Paul and Max said Luigi was not “arrogant” but had strong opinions. “He felt his way was the right way to do stuff,” one of the travelers said.

They also said Mangione attempted to help support an Indian author’s book by ordering hundreds of copies. The book, “Hit Reverse: New Ideas From Old Books,” was released in early December last year, and is from internet personality Jash Dholani.

TMZ says they verified that Mangione traveled to Mumbai, and Dholani confirmed the two met and spoke for about an hour. TMZ said Dholani did not provide specifics about their conversation.

NYPD intelligence analysis report

A NYPD Intelligence Bureau report said Mangione viewed the killing of Thompson as a symbolic takedown of the health care insurance industry, according to the “20/20″ special.

Police found notes in Mangione’s backpack at the time of his arrest and said he ruminated on ways to carry out his attack, according to the special. He considered using a bomb but “decided he didn’t want to kill innocents,” ABC7′s Josh Einiger said during the program.

Prosecutors allege Mangione had written material with him that expressed hostility toward the health insurance industry and especially wealthy executives.

More Mangione to come

Mangione in December pleaded not guilty in a New York state court to multiple counts of murder, including murder as an act of terrorism. He’s also facing federal charges that could carry the possibility of the death penalty. The two cases will proceed on parallel tracks, prosecutors have said.

Last month, an attorney for Mangione told a judge that government officials have turned him into a political pawn. “I am very concerned about my client’s right to a fair trial,” said Karen Friedman Agnifilo.

As the duel cases unfold, more documentaries on Mangione and the killing are in the works.

At least two feature-length documentaries have been announced, according to Vulture, and Investigation Discovery is working on an hourlong special that could air as soon as next month.

Mangione is being held in the Metropolitan Detention Center in Brooklyn, the same facility where Sean “Diddy” Combs is currently and where Sam Bankman-Fried was held for months.
