Inside the family of Luigi Mangione, suspect in UnitedHealthcare CEO's killing

Luigi Mangione, a 26-year-old man has been charged by investigators with murder over last week's fatal shooting of United Healthcare's chief executive, Brian Thompson, in New York City. People in his inner circle and those who knew his prominent and well-respected business family in Maryland are in disbelief and are struggling to comprehend Luigi's transformation from a star student to murder suspect.
Smart, accomplished and talented, Mangione, is an Ivy League tech graduate and quite popular in his circle. He is known to have interest in discussions on philosophy, psychology and evolutionary biology. In the last few months Mangione began experiencing severe back pain, which he described as a misalignment of his spine, causing nerve issues that left him in constant discomfort. The pain grew so intense that it disrupted his ability to participate in activities he once enjoyed, including surfing lessons with members of a community he had joined.
Apart from his physical struggles, Mangione’s mental health appeared to deteriorate. He grew distant from his friends and family, which was a cause of concern for them. While his earlier social media posts were more about technology, self-improvement, and healthy living, they started to grow more erratic. One of his last posts included a review of the Unabomber’s manifesto, a chilling hint of his shifting mindset.

As the valedictorian of his high school class in 2016, Mangione was praised for his intellect and ambition. He excelled in computer science and in fact created a mobile app in high school that allowed users to fly a paper airplane through obstacles. In college, he furthered his passion, earning bachelor’s and master’s degrees at the University of Pennsylvania and becoming a member of the Eta Kappa Nu academic honor society.
Friends from his high school and college days recall Mangione as bright, friendly, and ambitious. Race Saunders, a former classmate, remembered him as a dedicated student and a hard worker. “We were all definitely leaning toward computer science,” Saunders said. Mangione’s work ethic and popularity with his peers painted the picture of a young man poised for success in the tech world.

Mangione’s grandfather, Nick Mangione Sr., and grandmother, Mary C. Mangione, made their mark by purchasing the Turf Valley Country Club and developing the surrounding golf course community. The Mangione family also owns Hayfields Country Club and founded Lorien Health Services, a nursing home company. The family is well-known for their charitable work and connections to Baltimore’s Italian-American community.
Nick once shared with the Baltimore Sun the story of his humble beginnings, recalling how he lost his Italian immigrant father at the age of 11 and grew up with barely any money. “I didn’t have two nickels to rub together when my father died when I was 11, yet I still became a millionaire,” he said. “What other country can you do that in? None that I can think of.”
Nick and his wife, Mary, earned widespread admiration in the Baltimore community for their philanthropy. They donated over $1 million to the Greater Baltimore Medical Center, where all 37 of their grandchildren were born, leading the hospital to name its obstetrics unit in their honor. The Mangione Family Foundation has also contributed significant funds to institutions such as St. Jude Children’s Research Hospital and the St. Joseph Medical Center at the University of Maryland.
The couple raised 10 children, six of whom attended the local college, and their legacy extends into Maryland’s political sphere. One of their grandchildren, Nino Mangione, serves as a member of the state’s House of Delegates.
The Mangione family, well-known and respected in Maryland, was left in shock after Luigi’s arrest. His cousin, Nino Mangione, a member of the Maryland House of Delegates, issued a statement on behalf of the family. “Our family is shocked and devastated by Luigi’s arrest,” Nino wrote. “We offer prayers to the family of Brian Thompson and we ask people to pray for all involved.” The statement concluded with a heartfelt message: “We are devastated by this news.”
The Mangiones also founded Lorien Health Services, which has nine locations. Lorien’s facilities can be found in Baltimore, Howard, Harford, and Carroll counties.
Nino Mangione, the cousin of Luigi, is a state delegate. He is a Republican candidate for Baltimore County Council. Nino Mangione wrote on Facebook on December 10 that he was postponing a fundraising event at Hayfields on because “of the nature of this terrible situation” involving his cousin.

The suspect’s late grandfather was born to Sicilian immigrants and developed real estate for his family, including a 1,000-acre golf club and resort hotel, according to his obituary on FamilySearch.org. He also went on to own two hotels, seven nursing homes, and two talk radio shows.
The suspect's grandmother Mary Mangione, passed away in 2023 at the age of 92 and was deeply involved in the community service. She held significant roles as a trustee for the Baltimore Opera Company, served on a county tourism board, and worked with various organizations, including the American Citizens for Italian Matters, as highlighted in an obituary from Loyola University.
Kathleen, Mangione's mother, is the owner of a funeral home in the area, as per Baltimore Fishbowl.

Mangione has two sisters MariaSanta and Luciana. The former is a physician at the University of Texas Southwestern, according to her Vanderbilt School of Medicine profile. Luciana, is a visual artist.
Luciana Mangione wrote “Praying for you,” in a now unavailable Insta post that had snapshot of her and her brother smiling on a beach.
