Luigi Mangione, the defendant of CEO of Unitedhealthcare, may have influenced last month’s deadly attack against the NFL headquarters in New York City, federal prosecutors argued in a new judicial presentation.
When carrying out the murder in the murder style of the CEO Brian Thompson last year on a Midtown Manhattan street, Mangione “hoped to normalize the use of violence”, instead of the reasoned dialogue, to achieve political objectives, prosecutors said. Prosecutors used the massive shot last month at the NFL headquarters in Midtown as an example.

On July 28, Shane Tamura brought an assault rifle to 345 Park Avenue, not far from where Mangione supposedly shot Thompson. Tamura fired and killed four people and, like Mangione, left writing so that the researchers would find it. Tamura, in a letter found in his body, blamed the NFL and football for causing CTE. Tamura played football in high school, but not beyond that level. (
CTE, or chronic traumatic encephalopathy, is a brain -related brain disease repeated in the head, often seen in military veterans and athletes, including soccer players, hockey players and boxers. It can only be diagnosed after the death of a person.
Mangione allegedly wrote “Deny”, “Depos” and “Delay” about the bullets used to kill Thompson, authorities said. In a notebook found after his arrest, Mangione supposedly wrote in a newspaper: “The goal is safe” because “verifies each box.”

“The murder was thus, by the defendant’s own admission, calculated to resonate beyond this specific victim and generate contempt, outrage or fear of the healthiest health insurance sector,” prosecutors said. “In a nutshell, the defendant hoped to normalize the use of violence to achieve ideological or political objectives. Since the murder, certain trimesters of the public, which are openly identified as acolytes of the accused, have increasingly begun to see violence as an acceptable, or even necessary, replacing the reasoned political disagreement.”
The Government believes that Mangione is part of partly because it represents a continuous danger in trying to influence others.
Federal prosecutors elaborated their reasoning to pursue capital punishment, as they urged a federal judge to deny a defense motion that requested additional evidence to support government theories.
Prosecutors said Mangione has no right to additional information at this stage of the case and argued that “the defendant is already in possession of probative support for aggravating government factors and there is no risk of surprise.”
Mangione declared innocent of Thompson’s murder on December 4. Mangione is accused of shooting the CEO several times using a 9 mm gun equipped with a silencer. He was captured in Altoona, Pennsylvania, several days later.
