Luigi Mangione describes daily prison routine in letter to nursing student following killing of UnitedHealthcare CEO

Luigi Mangione’s daily routine at a Brooklyn detention facility consists of reading, eating ramen, and attending chess nights with his fellow incarcerated ‘brothers’, according to a new notice.

Last year, 26-year-old Mangione was charged with the murder of Brian Thompson, 50, the CEO of UnitedHealthcare, who was fatally shot outside of a hotel in New York City on December 4.

Following a nation-wide manhunt, the suspect was taken into custody at a McDonald’s restaurant in Pennsylvania, on December 10, before being indicted on eleven New York state charges, including murder in the first degree and criminal possession of a weapon in the second degree, by the Manhattan district attorney’s office on December 17.

Two days later, Mangione received an additional four federal charges, including two counts of stalking, murder through use of a firearm, and a firearms offense.

Mangione has pled not guilty to the charges he is facing.

Currently, the suspected murderer is being detained at the Metropolitan Detention Centre in Brooklyn without bond—the same establishment that Sean ‘Diddy’ Combs is currently being held in ahead of his trial on racketeering and sex trafficking offenses.

Mainly used for post-arrest detention for people awaiting trial in federal courts in Manhattan or Brooklyn, past and current high-profile inmates of MDC Brooklyn include rapper 6ix9ine, Smallville actress Allison Mack, R. Kelly, and luxury real estate agents Tal, Oren and Alon Alexander.

The United States federal administrative detention facility was opened in the 1990s and is reported to have had around 1,174 detainees, according to the Federal Bureau of Prisons.

According to U.S. District Judge Gary Brown, ‘chaos’ and ‘uncontrolled violence’ reign at the jail, with defense lawyer Xavier Donaldson claiming MDC has ‘a way of breaking people’, as per NBC News.

As well as an outdoor recreation facility, MDC Brooklyn consists of a medical unit with examination rooms and a dental suite, as well as a separate wing for educational programs and the jail’s library, reports the Associated Press.

Well, Mangione, who was transferred to the notorious detention building on December 19, has apparently now lifted the lid on what his life is like inside its four walls.

As reported by The Express Tribune, a social media user has taken to Reddit to share a picture of a letter she claims is from the University of Pennsylvania graduate.

The image of the letter was first shared via the popular Chinese social media app, RedNote.

After thanking Genevieve, the woman the letter is addressed to for reaching out, Mangione allegedly reported on February 26 that he had a ‘fair’ holiday season and that he was doing ‘just fine’ while awaiting trial for the murder of Thompson.

“My usual routine includes reading, eating lots of ramen, exercising, and spending time with my fellow brothers here,” the letter reads.

“We have chess nights on Wednesday, and it’s a fun way to pass time together.”

Mangione then apparently goes on to recommend that the letter reader read a book by Kristin Neff titled Self-Compassion: The Proven Power of Being Kind to Yourself, remarking it was a ‘great source of support for [him] during [his] freshman year of college’.

“I understand the feeling of wanting to give up at times,” the letter continues. “Navigating young adulthood can be tough, but I believe we can all find our way through.

“I wish you the best of luck with your graduation next semester. You have a bright future ahead.”

The Reddit post has proved popular, with hundreds of users coming out to debate the letters’ contents.

“Wow. I'm surprised he is able to comfort people who write to him even in his circumstances.

“At least he seems to be enjoying his time with his inmates who he's referring to brothers lol,” one wrote of Mangione, who has been described as a ‘model prisoner’ by veteran of New York City's criminal justice system, Karen Friedman Agnifilo.

Someone else responded: “50 years from now they’re going to sell books of all these letters over the years. It’s wild what has evolved from what he did.”

“Is there any chance these letters would be used in his upcoming trial to defend him?,” a third commented.
