Luigi Mangione Wants a Laptop in Jail So He Can Review '15,000 Pages' of Evidence

Luigi Mangione is asking for a laptop in jail while he awaits his trial so that he can keep up with the "voluminous" amount of discovery evidence prosecutors are expected to provide. 

Mangione, who is in custody at Brooklyn's Metropolitan Detention Center in connection with the Dec. 4 killing of UnitedHealthcare CEO Brian Thompson, made the request in a court filing this week. 

In a filing in New York State Supreme Court reviewed by PEOPLE, his defense attorneys Karen Agnifilo, Marc Agnifilo and Jacob Kaplan said that given the volume of discovery material, there “are not enough visiting hours” for the suspected shooter to review the prosecution’s evidence that includes “thousands of hours of video.”

The discovery information includes more than 15,000 pages of information and 800 GB of data, per the filing. 

The Manhattan District Attorney's office is resisting the request, Mangione's attorneys claim, because of purported "threats" against witnesses. His lawyers say these claims should not be taken seriously.

The DA's office "has no basis to believe that Mr. Mangione has any connection to the alleged witness threats," Mangione's attorneys claim in the filing.

Furthermore, the fact that prosecution has reportedly not yet shared information about witnesses with the defense is an indication that Mangione is not connected to the threats, the filing said.

A laptop at the facility is not entirely uncommon, according to Sam Mangel, prison consultant currently working with other inmates at the same facility hosting Mangione.

Mangel echoed the defense's note in the filing that other prisoners have access to laptops, which are disconnected from the internet to comply with federal prison regulations.

"There's a procedure for doing this, but it is not difficult," Mangel tells PEOPLE.

Mangione's jailmate at MDC, Sean "Diddy" Combs, was granted access to a laptop in December to review discovery in his case; the hip hop mogul is accused of sex trafficking by federal prosecutors.

Mangione is currently being held at held at MDC, a federal facility, on murder charges in connection with Thompson's shooting. He has pleaded not guilty to the state charges but has not yet entered a plea on the federal charges.

A spokesperson for the Manhattan DA's office said prosecutors will "respond in court paper" to the motion. Mangione's lawyers did not immediately respond to PEOPLE's request for comment.
