US judge grants accused CEO killer Mangione's bid to suppress evidence due to unlawful search

A United States court judge on Monday partially granted Luigi Mangione’s bid to ‌prevent evidence found in his backpack during his arrest from being admitted at his murder trial for allegedly assassinating a health insurance executive in Manhattan.

Mangione, 28, is accused of gunning down United Healthcare CEO Brian Thompson on a Midtown sidewalk in December 2024. Public officials condemned the brazen killing, but ​it became emblematic of some Americans’ antipathy towards health insurance industry practices and rising costs.

Mangione has pleaded not guilty ​in state court to all charges. His trial is set to begin on September 8 and is ⁠expected to last six weeks.

The ruling is a legal boost for Mangione, although prosecutors say they have ample evidence of his ​guilt.

Justice Gregory Carro granted Mangione's request to suppress some of the evidence found in his backpack during his arrest in Pennsylvania, ​ruling police unlawfully searched the bag without a warrant. That evidence included a loaded handgun magazine, a cell phone and a computer chip.

However, Carro ruled that a second search of the backpack at a police station was lawful and that items recovered then, including a gun, silencer, USB drive and red notebook, ​would be admissible.

Carro denied Mangione's bid to suppress his initial statements to law enforcement, rejecting his argument that he was illegally ​interrogated.

The judge announced his decision during a brief hearing at a New York state court in Manhattan, with Mangione in attendance.

Mangione’s lawyers argued ‌that ⁠the contents of his backpack and statements to law enforcement during his arrest in Pennsylvania should be inadmissible because he was illegally searched and not given notice of his legal rights.

Prosecutors with the office of Manhattan District Attorney Alvin Bragg deny claims that Mangione was illegally searched and questioned.

In court filings, prosecutors have detailed a broad range of evidence linking Mangione to the killing, including ​DNA, fingerprints, hundreds of hours of ​video footage, a cell phone ⁠and another backpack that he allegedly dropped during his flight from New York.

Thompson, who led UnitedHealth Group's health insurance business, was shot and killed on December 4, 2024, outside the Hilton hotel ​where the company was holding an investors’ meeting.

Mangione was arrested in Pennsylvania after a five-day ​manhunt and has ⁠been jailed ever since.

State prosecutors initially charged Mangione with terrorism, but Carro threw out that charge after finding there was not enough evidence to show Mangione’s alleged actions were aimed at influencing public policy.

Federal prosecutors with the US Attorney’s Office for the Southern District of New ⁠York separately ​brought murder, weapons and stalking charges against Mangione.

The judge overseeing that case ​threw out the murder and weapons charges on a legal technicality in January. That eliminated the possibility of the death penalty, but Mangione could face life in ​prison if he is convicted of stalking.
