(NewsNation) — Fingerprints taken from Luigi Mangione match those found on a water bottle near the place in New York City where United Healthcare CEO Brian Thompson was fatally shot last week.
The water bottle was in an alleyway Mangione allegedly ran to after the shooting, sources told NewsNation affiliate WPIX.
Thompson, 50, was killed just before 7 a.m. Dec. 4 near a Midtown Hilton Hotel while he was walking to UnitedHealth Group’s annual investor meeting.
NYPD officers searched for the gunman in New York and Georgia. On Dec. 9, police in Altoona, Pennsylvania, responded to reports of a man matching authorities’ description of the suspect at a local McDonalds.
It was there that Mangione was arrested. The NYPD said Mangione matched the description authorities were searching for, and that he had with him a mask, firearm, suppressor and fake New Jersey ID that connected him to the shooting.
New reporting shows Mangione also had a manifesto and spiral notebook with a “to-do” list. Mangione allegedly wrote in the manifesto he acted alone, and that he “apologizes for any strife or traumas, but it had to be done.”
“Frankly, these parasites had it coming,” the manifesto says.
Luigi Mangione’s extradition hearing
As he was escorted into a Pennsylvania courthouse Tuesday after his arrest, Mangione shouted to reporters gathered outside.
“It’s completely an injustice and an insult to the American people,” he said.
During his extradition hearing Tuesday, Mangione tried to interrupt and talk with his attorney, Thomas Dickey.
The state of Pennsylvania is pursuing a governor’s warrant for 26-year-old Mangione, who is currently at the State Correctional Institution Huntingdon. That process could take 30 days, especially as Mangione is trying to fight it.
Dickey told NewsNation’s Chris Cuomo that he believes that Mangione will plead not guilty.
“We’ve seen no evidence. We’ve seen nothing,” Dickey said on “CUOMO” Tuesday. “I don’t want people to jump to these prejudgment things because nobody would ever want that if they were accused, or one of their loved ones were accused.”
In the months leading up to the shooting, Mangione’s mother reported him missing to police in San Francisco, California, the New York Police Department’s Chief of Patrol, John Chell, said.
Mangione’s mother told law enforcement that her son wasn’t returning phone calls and text messages or posting on social media.
Several GoFundMe accounts have been set up so people can donate to pay Mangione’s legal bills. GoFundMe says they are quickly working to shut these down.
