BURSTLuigi Mangione, the suspect in the shooting of UnitedHealthcare CEO Brian Thompson, was arrested Monday morning after the search for a killer behind the health care executive’s death enraptured the nation for days.
Mangione was charged with five crimes after his arrest in Pennsylvania, according to a criminal complaint, including forgery and carrying a firearm without a license. He has also now been charged with murder in New York City, where the shooting took place.
There are questions swirling around what Mangione’s motive may have been.
Here’s what to know about the potential motive of the suspect in Thompson’s shooting:
The note
Mangione wrote in a note that “these parasites had it coming," according to law enforcement officials who spoke to The Associated Press on condition of anonymity.
“To the Feds, I’ll keep this short, because I do respect what you do for our country. To save you a lengthy investigation, I state plainly that I wasn’t working with anyone,” Mangione said in the note, according to AP.
“I do apologize for any strife or traumas but it had to be done. Frankly, these parasites simply had it coming,” he added later, the AP reported.
The reported note suggests that Mangione may have viewed Thompson as meeting that description.
New York Police Department (NYPD) Chief of Detectives Joe Kenny has said that Mangione wrote a three-page document in which he voiced “some ill will toward corporate America.”
The shell casings
Police recovered three live 9 mm rounds were recovered from the scene of the shooting. According to NBC News, a top New York City law enforcement official said the shells featured the words “deny,” “defend” and “depose" on them.
The words mirrored those of the title of a book, “Delay, Deny, Defend: Why Insurance Companies Don’t Pay Claims and What You Can Do About It,” the New York Post later reported.
Shouting at the media
Mangione shouted at news media outside of a Pennsylvania courthouse on Tuesday when officers were moving him inside for an extradition proceeding. He could be heard saying “completely out of touch” and “an insult to the intelligence of the American people” when officers gathered around him and led him to a door.
