In his first comments since Luigi Mangione was charged Monday with second-degree murder, Manhattan District Attorney Alvin Bragg said he was confident the 26-year-old would be quickly extradited to New York, where he would be held accountable. brave shooting UnitedHealthcare CEO Brian Thompson.
“We will bring the defendant here and bring him to justice through our legal process,” Bragg told ABC News on Wednesday, adding that Mangion could face additional charges beyond the second-degree murder charges he currently faces.
“As we learn more about the motives and other things like that … there could be additional charges,” Bragg said.

Mangione is also charged in New York with several counts of possession of a forged instrument and possession of a weapon.
“We plan to learn more, and we have a lot to do,” Bragg said. “As things progress, we may incur additional expenses,” Bragg said.
Mangione’s attorney, Thomas Dickey, said his client plans to plead guilty to the charges, saying there is no evidence linking his client to the crime. Bragg said he was confident Mangione was the person who shot Thompson three times in the torso last week, killing the health care executive and sparking a storm of vitriol online.
“We wouldn’t have charged the person if we didn’t believe it was that person, and we’re ready to move forward and move toward accountability and justice,” Bragg said.
After the former Ivy Leaguer is extradited to New York, Bragg said Mangion will face a team of Manhattan’s most experienced homicide prosecutors. The DA has admitted that the nature of the alleged crime is “extremely appalling”.
“It’s very scary, and it’s something that has the attention of many who live here, the attention of many who come to work here, and rightfully so,” Bragg said.
Bragg’s comments come the same day the New York Police Department offered the first forensic evidence linking Mangione to the alleged crime. According to Police Commissioner Jessica Tisch, fingerprints from the crime scene were matched to Mangione, and three shell casings recovered after the downtown shooting were matched to Mangione’s 3D printed gun. Bragg’s office said his office has been focused on fighting so-called ghost guns since he began his tenure as district attorney.
“It’s something we’re using more and more, generally speaking. It’s also something we’ve seen younger and younger people working on,” Bragg said.
When asked if Mangione was charged with second-degree murder, Bragg told ABC News that prosecutors wanted to bring charges quickly and that first-degree murder “has some specific circumstances.”
“Murder 2 is the intentional killing of a person, punishable under New York law by 25 years to life,” Bragg said. “Murder 1 is defined by various circumstances, including, for example, a serial murder, the murder of a witness, the murder of a police officer.”

Bragg has found himself at the center of multiple high-profile cases, including the conviction of former President Donald Trump and the acquittal of Marine veteran Daniel Penny. With the Mangione case, Bragg is expected to not only face a high-profile indictment, but also an outpouring of public support for the accused killer.
“I … have spent time with families of homicide victims and survivors of violent crimes,” Bragg said. “That is the focus of our work, and it is incomprehensible to me to think that there are others who celebrate this behavior.”

Thompson’s killing sparked online outrage against the health insurance industry and some people online have celebrated the suspect.
“Celebrating the kill is terrible,” Bragg said. “I sit across the table from families who have lost a loved one. And to think of people celebrating that … it’s beyond comprehension.”

“What I would say to members of the public … who are celebrating this and maybe coming up with other actions is we’re going to be vigilant and hold people accountable,” Bragg said.

Mangion plans to contest his extradition to New York.
The Manhattan District Attorney’s office said it will seek a warrant from the governor to try to compel Mangione’s extradition. New York Gov. Kathy Hochul said in a statement that she will sign a petition for a gubernatorial order “to hold this individual accountable and prosecuted.”
