Murder Trial for UnitedHealthcare CEO’s Killing Set to Begin in September
Federal prosecutors and defense attorneys gathered Friday as U.S. District Judge Margaret Garnett set September 8 as the start date for jury selection in Luigi Mangione’s high-profile murder trial. The 27-year-old defendant faces charges in the killing of UnitedHealthcare CEO Brian Thompson.
The trial timeline remains partially fluid, with Judge Garnett establishing different schedules depending on whether prosecutors pursue the death penalty. If capital punishment remains an option, the substantive phase of the trial would begin January 11, 2027—more than four months after jury selection starts. Without the death penalty in play, opening statements would commence on October 13, reflecting the significantly less complex nature of non-capital cases.
Mangione has entered not guilty pleas to both federal and state murder charges, which could result in a life sentence. The state trial date remains unscheduled.
The defendant appeared in court Friday for a hearing focused on evidence procedures, specifically regarding police seizure of his backpack following his December 9, 2024, arrest at a McDonald’s restaurant in Altoona, Pennsylvania—approximately 230 miles west of Manhattan, where Thompson was killed five days earlier.
The defense team is challenging the admissibility of crucial evidence found in Mangione’s backpack, including what prosecutors describe as the murder weapon and a notebook allegedly containing written plans to “wack” a health insurance executive. The legal dispute centers on whether Altoona police followed proper search protocols.
Altoona Police Department Deputy Chief Nathan Snyder testified for approximately 90 minutes during the hearing. Judge Garnett had specifically requested testimony regarding “established or standardized procedures” for handling personal property during public arrests. Though prosecutors noted that Snyder—who was promoted just three weeks ago—had no direct involvement in Mangione’s arrest, the judge found his testimony “very helpful” but issued no immediate rulings.
Mangione’s appearance marked a change from previous court appearances, as he attended wearing a tan jail suit with a chinstrap beard instead of his typical clean-shaven look. His next federal court appearance is scheduled for January 30 for a status conference.
The defense arguments echo those recently presented in state court, where Mangione’s attorneys contend the Altoona Police Department’s search was illegal because officers had not obtained a warrant before examining the backpack’s contents. The state judge is expected to rule on evidence admissibility in May.
Thompson was fatally shot on December 4, 2024, while walking to a Manhattan hotel where UnitedHealth Group was holding its annual investor conference. Surveillance footage captured a masked assailant shooting the executive from behind in what investigators believe was a carefully planned attack.
According to court documents, officers began searching Mangione’s backpack immediately after his arrest while he was eating breakfast. Prosecutors maintain the search was legal under Altoona police protocols, which require immediate examination of a suspect’s property for dangerous items. Officers later secured a warrant to continue their investigation.
The initial search revealed a loaded gun magazine. At the police station, further examination uncovered the alleged murder weapon, a silencer, and the notebook containing what prosecutors describe as incriminating notes, including apparent to-do lists and possible escape plans.
Prosecutors argue that the station search constituted a standard “inventory search”—a cataloging of all seized property that is mandated by department policy. The defense has suggested that examining the backpack before obtaining a warrant may have influenced how the search warrant affidavit was written, though prosecutors counter that specific details about items like notebook contents were not mentioned in the document.
The case has drawn significant attention within the healthcare industry and financial markets, as Thompson was a prominent executive at one of America’s largest health insurance companies. His killing sent shockwaves through the business community and raised questions about executive security protocols at major corporations.
