NEW YORK (AP) — Luigi Mangione is due in federal court Friday for a pivotal hearing in his fight to prevent the government from pursuing the death penalty in the murder case against him for the killing of UnitedHealthcare CEO Brian Thompson.

Mangione’s lawyers argue that the manner in which authorities handled his December 2024 arrest turned the situation into a sensationalized event akin to a 'Marvel movie'. They also contend that prior statements regarding the intention to seek the death penalty unfairly influenced the public perception before any formal charges were brought.

If their motion to restrict the death penalty fails, Mangione’s defense will seek to have the primary murder charge of firearm-related murder dismissed on the grounds of legal insufficiency.

Federal prosecutors counter that Mangione's assertions overreach, stating that the murder charge holds legal ground and citing that intense pretrial publicity does not infringe upon fair trial rights if jurors are adequately screened for bias.

Mangione has professed his innocence, pleading not guilty to both federal and state charges, which could lead to a life sentence if convicted.

This hearing marks Mangione's first appearance in Manhattan federal court since his arraignment on April 25. The hearing is also expected to address defense motions regarding the exclusion of certain types of evidence. U.S. District Judge Margaret Garnett has indicated she will likely set a trial date during this session.

Support for Mangione has been notable, with numerous supporters attending his court appearances, donning green attire and holding placards that express solidarity.

Mangione's legal team is particularly seeking to prevent the use of evidence obtained from a backpack at the time of his arrest, where a gun and a notebook detailing his intent were located. The legality of the search remains a contentious issue in negotiations, with the defense arguing for a separate hearing to thoroughly consider the evidence in question.

Thompson's murder has sent ripples through the healthcare community, as he was fatally shot on December 4, 2024. Surveillance footage captured the harrowing moment of his assassination, described by authorities as a premeditated act.

Mangione, a 27-year-old Ivy League educated individual from a wealthy family, was detained shortly after in Pennsylvania. His extensive legal battles have already seen some measure of success, with previous terrorism charges being thrown out in a state court.

U.S. Attorney General Pam Bondi previously announced the decision to pursue the death penalty, stating it was warranted for such a “cold-blooded” act, a declaration that the defense has criticized as politically motivated and damaging to the integrity of the judicial process.
