Attorneys for Luigi Mangione, the Towson, Maryland, man accused of gunning down a United HealthCare CEO, are requesting he have access to a laptop while in federal custody to review documents and other material related to his case, according to a court filing Monday in the Supreme Court of New York.

Without a laptop, counsel would have to print out more than 15,000 pages of discovery for Mangione to keep in his cell pending his trial, his attorneys, Karen Friedman Agnifilo, Marc Agnifilo and Jacob Kaplan, said in the court filing.

However, prosecutors “do not plan on consenting to a personal laptop at this time” because of the sensitive nature of many of the documents and alleged threats to witnesses in the case.

Mangione, 26, faces federal and state charges in connection with the death of CEO Brian Thompson. Mangione, a 2016 Gilman valedictorian and graduate of the University of Pennsylvania, is charged with multiple counts of murder, including murder as an act of terrorism.

“There is no good reason why Mr. Mangione has not been provided with complete discovery, all of which is entirely in law enforcement’s possession,” Mangione’s attorney said in the court filing. “Not only is there no legitimate basis for a protective order to withhold this information from the defense, but there is also no connection between Mr. Mangione and any purported threats to anyone.”

Mangione’s counsel noted that many other federal inmates at the prison are provided laptops to review their discovery. In those cases, counsel obtains a laptop and provides it to an approved vendor to modify in compliance with the prison’s regulations by disabling the laptop’s connections to the internet, printers, wireless networks, games, and entertainment programs.

Mangione’s legal team declined to comment, referring all questions to the latest court filing.

This case has generated international interest and has become a rallying cry for those who share Mangione’s apparent anger with the health insurance industry.

Mangione is accused of shooting Thompson outside a New York City hotel on Dec. 4 as he headed to UnitedHealth Group’s annual investor meeting. He is accused of carefully planning the murder — traveling to New York to find him, carrying a gun with a silencer to carry out the killing and developing a document that chronicled his disdain for the insurance industry, which law enforcement said they found on him at the time of his arrest.

He was later arrested at a McDonald’s in Altoona, Pennsylvania, with a gun suspected of being linked to the three shell casings discovered at the crime scene. Investigators said his fingerprints matched those investigators found on a water bottle and snack bar wrapper.

Mangione has 11 New York state charges, including first-degree murder in furtherance of terrorism.

Federal charges against him include two counts of stalking and one count each of murder through the use of a firearm, which carries the possibility of the death penalty, and one count of discharging a firearm that was equipped with a silencer in “furtherance of a crime of violence, which carries a maximum potential sentence of life in prison and a mandatory minimum sentence of 30 years,” according to U.S. Attorneys in the Southern District of New York.

In addition, he has been charged with gun and forgery offenses in Pennsylvania. He was held there until Dec. 19, when he was extradited from the Blair County Courthouse to New York to face the most serious offenses.

Last month, more than 100 mostly female supporters crowded into the hallways of a New York criminal court to support Mangione in a court appearance. His attorneys have questioned whether he will be able to get a fair trial because of the publicity surrounding the case and some tactics by the prosecutors, who allegedly discussed evidence publicly without sharing it with the defense team.

“To make matters worse, while the prosecution is deliberately withholding discovery from the defense, law enforcement is routinely providing information to the public, including confidential Grand Jury information, in clear violation of Mr. Mangione’s constitutional rights,” the latest court filing reads. “Since the inception of this case, the defense has learned a great deal about the discovery in the People’s possession from leaks and interviews given by law enforcement, even as recently as 11 days ago in a New York magazine profile of the police commissioner.”

A fundraiser on GiveSendGo that is raising funds to help Mangione pay for his legal defense has reached $757,702 toward its goal of $1 million.

Officials with the Manhattan district attorney’s office could not be reached for comment.

Mangione’s next federal court hearing is scheduled for April 18. He is set to make another appearance in state court in June.
