As Luigi Mangione faces trial for the alleged murder of UnitedHealthcare CEO Brian Thompson, his sister is embarking on a notably different journey.
MariaSanta Mangione, aged 36, is about to begin a fellowship in cardiovascular disease at the renowned Johns Hopkins University, the Daily Mail has learned.
This program is one of the most sought-after in the medical field, with aspiring cardiologists dedicating years of hard work to gain entry.
The situation underscores the divergent paths of the Mangione siblings since the 28-year-old Luigi was accused in connection with Thompson’s death.
Luigi has two older sisters: MariaSanta and Lucia Mangione Giulio, 34, who resides in Baltimore, where she pursues her career as an artist. Lucia married Paul Giulio in June 2022 in her hometown.
The family has issued only one public statement regarding Luigi’s alleged involvement, expressing that they are learning details from the media and are ‘shocked and devastated’ by his arrest.
They added that they wanted to ‘offer prayers to the family of Brian Thompson and we ask people to pray for all involved.’
And now, while Luigi sits in a cell in Brooklyn, his sister is preparing to continue her stellar career in medicine.

Pictures of MariaSanta smiling in her doctor’s coat paint a stark comparison to those of her brother that took over social media after his arrest – gaining him a devoted following of female supporters who attend court hearings.
Writing in October 2024, Mangione said he wanted to ‘whack’ the chief executive of an insurance company at its annual ‘bean counter conference’.
Six weeks later, Thompson, 59, a father of two, was shot outside the Hilton Midtown in Manhattan during a UnitedHealthcare conference.
A social media post by Johns Hopkins confirmed that MariaSanta will begin her fellowship in July – two months before her brother is due to stand trial.
Unlike her younger brother, MariaSanta has spent more than a decade building a career in medicine and scientific research.
She earned a degree in Cell Biology and Molecular Genetics from the University of Maryland before completing the highly selective M.D./Ph.D. physician-scientist program at Vanderbilt University School of Medicine, where she conducted research into the cellular mechanisms of disease.
Following her graduation from Vanderbilt, she completed an internal medicine residency at UT Southwestern Medical Center in Dallas and went on to specialize in cardiology.
Alongside her clinical training, she has published cardiovascular and biomedical research and has previously received competitive research funding during her academic career.

MariaSanta did not immediately respond to a Daily Mail request for comment.
Their family has essentially become recluses since Luigi’s arrest in Altoona, Pennsylvania, in 2024, with his mother Kathleen reporting him missing prior to the murder that shocked America.
The family was well known in Maryland long before Luigi’s arrest.
His grandfather, the late businessman Nicholas Mangione, built a real estate empire that included Turf Valley Resort and Hayfields Country Club as well as Baltimore radio station WCBM-AM after growing up in a working-class family in Baltimore’s Little Italy.
Following his death in 2008, control of the family empire passed to his children, including Luigi’s father Louis.
His mother, Kathleen Zannino Mangione, owns a boutique travel company, although its website has remained offline since her son’s arrest.
Other family members have largely disappeared from public view, though MariaSanta recently reinstated her LinkedIn profile ahead of her move to Johns Hopkins.
Gates enclosing the porch of his parents’ $2.3 million home in Cockeysville, Maryland, are locked to prevent any unwanted visitors from approaching the mansion on the grounds of the exclusive Hayfields Country Club.
On the grassy verges approaching the club are campaign signs for another member of the Mangione family reaching a milestone while Luigi remains behind bars.
His cousin, Republican politician Nino Mangione, was recently appointed to the Baltimore County Council after being selected to fill a vacant seat left by longtime councilman Wade Kach, who stepped down for health reasons.

Luigi Mangione’s great-grandfather Nicholas founded the nursing home Lorien Health Services. Luigi volunteered at the nursing home in 2014, according to his LinkedIn page
Mangione was chosen from a field of seven Republican applicants and could represent roughly 120,000 constituents through the end of the year. He did not respond to a request for comment.
The 38-year-old, who previously served in the Maryland House of Delegates, has said he was ‘very excited to hit the ground running’ after being sworn into the role and pledged to ‘do the best we can for the people of Baltimore County’.
He is a prominent supporter of President Donald Trump, once describing the president as the person he admires most. He resigned his delegate seat after being sworn into the council.
Nino was also the family member who publicly addressed Luigi’s arrest in December 2024, issuing the statement on behalf of the Mangione family.
Since then, he has largely declined to discuss his cousin publicly while continuing his political career.
The developments offer a glimpse into how life has continued for members of the family even as Luigi’s future hangs in the balance.
While he awaits his day in court, relatives have continued to build careers in medicine and politics far from the legal battle that has made headlines around the world.
The latest family milestones come as Mangione’s criminal case continues to generate controversy.
UnitedHealthcare CEO Brian Thompson was shot and killed outside Manhattan’s Hilton Hotel in December 2024
Last week, a New York state judge held a closed-door hearing after granting a request from the defense team, excluding both the public and the press and drawing objections from media organizations seeking access to the proceedings.
Mangione scored a partial victory in May after a judge threw out some of the key evidence recovered during his arrest – but ruled jurors will be allowed to see his alleged ‘manifesto’ and the 9mm ghost gun at his murder trial.
Judge Gregory Carro decided the jury will be shown the notebook that was found in Mangione’s backpack by police in which the Ivy League graduate allegedly wrote that he wanted to ‘whack’ a senior figure in the health insurance industry.
According to prosecutors, a journal entry from October 2024 allegedly described the investor conference as ‘a true windfall’.
The journal is said to state: ‘It embodies everything wrong with our health system.’
In another entry from August 2024, Mangione allegedly wrote: ‘I finally feel confident about what I will do. The details are coming together.
‘And I don’t feel any doubt about whether it’s right/justified. I’m glad, in a way, that I’ve procrastinated because it allowed me to learn more about (UnitedHealthcare).
‘The target is insurance. It checks every box.’
Police who arrested Mangione said that the bullets in the magazine convinced them he was the killer.
According to prosecutors, the bullets used to kill Thompson had the words ‘delay’, ‘deny’ and ‘depose’ written on them in reference to the language allegedly used to deny health insurance claims.
The family’s patriarch, the late Nicholas Mangiano, was the owner of Turf Valley Resort, pictured, and Hayfields Country Club, as well as the radio station at the WCBM-AM

Mangione also caught a break in the separate federal case, which is taking place in New York in a courtroom a few blocks from the state court.
US District Judge Margaret Garnett dismissed four of the federal counts, including murder through the use of a firearm and a related firearms offense.
Critically, the dismissal of the murder charge meant Mangione is no longer eligible for the death penalty.
Mangione still faces two counts of interstate stalking, which carry a maximum sentence of life in prison without parole.
The federal case is due to go on trial next year once the state matter is concluded.
His defense team has argued that investigators misrepresented comments allegedly made by his mother, Kathleen, in the days after Thompson’s killing.
New York authorities previously suggested she had told police she could see her son carrying out such a crime, but a San Francisco police sergeant later testified that he never heard her make the remark and never relayed any such statement to investigators.
At a previous hearing, ‘One plus one equals two,’ Mangione yelled, per Fox5 reporter Michelle Ross, who was in court.
‘This is the same trial twice. This is double jeopardy by any common-sense definition.’
Double jeopardy means that a person cannot be prosecuted for the same offense twice.
However, alleged criminals can face the same charge in both state and federal courts if the crime occurred in multiple jurisdictions.
His attorney, Karen Friedman Agnifilo, said Mangione is stuck in a ‘tug of war between two different prosecution offices’.
Mangione is currently being held at the grim Metropolitan Detention Center, a federal prison in Brooklyn whose previous inmates included R. Kelly and Diddy.
