Who is Luigi Mangione?
Mangione grew up in Towson, Maryland, as part of a wealthy and influential family. His family is known for their business ventures in real estate, healthcare, and philanthropy, as well as their ties to local politics.
He attended Gilman School, an elite all-boys private school in Baltimore, where he graduated as valedictorian of the Class of 2016. Known for its rigorous academics and exclusive reputation, Gilman School has produced many prominent alumni.

Mangione’s educational achievements continued at the University of Pennsylvania, where he earned a bachelor’s and a master’s degree in computer science with a minor in mathematics.
He was a student leader, serving as founder and president of UPenn’s Game Research And Development Environment (UPGRADE) program. His academic career was supplemented by notable internships and jobs.
He worked at John Hopkins University as a robotics researcher, interned at Firaxis Games, and served as a summer counselor at Stanford University. After graduation, he took on the role of data engineer at TrueCar Inc.

With such a promising academic and professional background, many are struggling to understand how he became a suspect in a murder investigation.
Friends and Colleagues Remember Him
People who knew Mangione have expressed shock and disbelief over his arrest. A spokesperson for R.J. Martin, founder of Surfbreak, a co-living space where Mangione stayed in Hawaii, said, “Luigi was just widely considered to be a great guy. There were no complaints.”
“It’s unimaginable,” Martin reacted to the allegations. A high school classmate recalled Mangione as “a smart kid” who was “always smiling” and socially friendly.
A former colleague from Stanford’s summer program remembered him as outgoing and socially charming, someone who never appeared troubled or antisocial. “I never got the impression he would self-destruct,” they added.
There have been consistent descriptions of him as intelligent, kind, and well-liked. However, most of those who knew him recall that he also dealt with serious health challenges.
Health Struggles and Isolation
In recent years, health struggles appeared to take a toll on Mangione’s life, with back issues and isolation being central themes. He suffered from spondylolisthesis, a spinal condition that worsened after a surfing injury while living in Hawaii.
This injury led him to undergo spinal fusion surgery, an intense procedure where screws are inserted into the spine to stabilize it. Mangione shared an X-ray image of his back on social media, revealing the large screws embedded in his spine.
But his health issues went beyond physical pain. Posts linked to his online presence mention “brain fog” that began after his college fraternity’s “hell week,” an initiation period known for sleep deprivation.

He also referenced health complications from Lyme disease, which compounded his struggles during college. His grades reportedly suffered as a result, with him calling his symptoms “life-halting.”
After his surgery, friends and family began to notice his absence. Social media posts reveal that some of his friends had been trying to reach him. One friend on X (formerly Twitter) posted, “Nobody has heard from you in months.”
Another friend urged him to check in. Some wonder if this period of isolation, combined with his health struggles, may have played a role in what happened next.
The crime that shocked New York unfolded in broad daylight. UnitedHealthcare CEO Brian Thompson was shot on a crowded sidewalk in Midtown Manhattan. At first, there were no named suspects, but police soon zeroed in on Mangione.
Police linked the evidence found at the scene to Mangione. The shell casings found on the scene were reportedly engraved with unusual words, “deny,” “defend,” and “depose” — all terms often associated with corporate health insurance practices.

During his arrest, police discovered a 3D-printed gun and silencer in his backpack. They also found a handwritten manifesto. The note reportedly referred to corporate America as “parasites” and included the phrase, “These parasites had it coming.”
He was charged with first-degree murder, two counts of second-degree possession of a weapon, and one count of possession of a forged document. Authorities have not yet established a motive for the killing but there are speculations.
Did Anti-Corporate Beliefs Motivate the Attack?
Evidence suggests that anti-corporate sentiment may have been a factor in the crime. This includes the handwritten note found at Mangione’s arrest and the shell casings from the crime scene. The words found on the casings are a known criticism of health insurance company tactics.
Further evidence comes from Mangione’s online activity. Investigators revealed that he had read and reviewed Ted Kaczynski’s manifesto, “Industrial Society and Its Future,” on Goodreads. He rated it four stars and wrote, “When all other forms of communication fail, violence is necessary to survive.”
Speculation has arisen that Mangione’s health struggles, isolation, and disillusionment with healthcare systems may have contributed to his alleged motive. Following his arrest, his family has broken their silence.
‘Shocked and Devastated’: The Mangione Family’s Reaction
Mangione’s arrest has drawn attention to his family, one of the wealthiest in Baltimore. The Mangione family has deep roots in the community, owning nursing homes, country clubs, and real estate properties.
His cousin, Nino Mangione, a state delegate in Maryland, released a statement expressing his family’s heartbreak and disbelief, saying they are “shocked and devastated” by Luigi’s arrest.
They also extended their sympathies to Thompson’s family, saying, “We offer our prayers to the family of Thompson and ask people to pray for all involved.” The family estate in Baltimore is now guarded by private security to protect their privacy.
Mangione faces charges of first-degree murder, possession of weapons, and possession of forged documents. If convicted, he could face life in prison.
What began as a promising life filled with opportunity has turned into a story of mystery and tragedy. From a great guy and his acquaintances having no complaints about him to a murder suspect facing life in prison, Luigi Mangione’s story has shocked many.
