Luigi Mangione should be spared the death penalty because prosecutors are more interested in putting on a “Marvel movie”-esque show than getting justice, his lawyers argued.

The 27-year-old’s legal team called for the entire case to be dismissed, or at the minimum his death penalty provision, saying his perp-walk was staged for the “political needs of federal and local officials and not for public safety.”

“In a show of force befitting a captured cartel chief or comic book villain, Mr. Mangione, at the time a 26-year-old who had never been in trouble with the law, was ‘perp walked’ before scores of television cameras and press reporters, surrounded by armed law enforcement officials in tactical SWAT gear and raid jackets,” his lawyers said in the 114-page Manhattan Federal Court filing.

Parading the handcuffed Mangione in front of news cameras after his arrest while more than one dozen officers and Mayor Adams were present poisoned the potential jury pool, his lawyers contended. 

“Potential jurors … were imprinted with a scene out of a Marvel movie, with dozens of agents needed to protect the public from the shackled monster Mangione.”

The accused killer‘s “beautiful, promising life” has been “derailed” by the murder allegations, they whined in court papers, citing his “intellect and character,” and “large, close, loving family,” adding, “he is now fighting for his life against a government that seeks to execute him.” 

Local and federal law enforcement compromised the case by declaring Mangione a “terrorist” in media appearances and violating his rights by “explicitly basing a death penalty decision on a political agenda,” his lawyers argued. 

Adams was facing his own indictment for accepting bribes at the time, and used Mangione as an opportunity to portray himself as a hero rather than a criminal, the accused killer’s reps contended. 

Meanwhile, US Attorney General Pam Bondi fumbled the case by “gratuitously telling the public that she has received death threats for seeking the death penalty against Mangione,” they griped.

“A more prejudicial statement by the nation’s Attorney General is hard to imagine,” Mangione’s lawyers argued.

Law enforcement also leaked notes they found on Mangione after his Dec. 9 arrest in Altoon, Pennsylvania to news media, his lawyers alleged.

“Law enforcement leaked these writings to the press as early as December 10, 2024, and …falsely described them as a ‘manifesto,’ a term used only by law enforcement to cast Mangione as a terrorist and to generate even greater amounts of press attention and public interest in the case,” the filing stated.

Neither the NYPD nor Tisch’s offices immediately returned requests for comment about the fresh allegations. A rep for Bondi referred inquiries to Manhattan Federal Court, which did not immediately respond to comment. 

Mangione is facing a second-degree murder charge and eight other counts for the cold-blooded killing of UnitedHealthcare CEO Brian Thompson outside the company’s investor conference in Midtown late last year.

Prosecutors allege the Maryland-native intentionally chose the Manhattan murder site in an attempt to stoke fear and usher in a “revolution” in the health insurance industry.

Video of the chilling murder showed Thompson walking alone along a Midtown street in the early morning of Dec. 4, before a backpack-clad hooded figure stepped up behind him with a long-barreled gun, and fired.

Mangione was arrested after a five-day manhunt. Cops in Altoona, Pa., allegedly discovered the red notebook, a partially 3D-printed pistol, zip ties and rolls of duct tape inside his backpack, authorities said.

On Tuesday, a Manhattan Supreme Court Justice tossed first- and second-degree murder as terrorism charges against Mangione.

He still faces 25 years to life in prison on the second-degree murder charge, but the judge’s ruling to toss out the terrorism charge means he will be eligible for parole if convicted at trial.
