A judge in the murder case against Luigi Mangione has ruled that a gun and notebook, which prosecutors argue connect him to the killing of UnitedHealthcare CEO Brian Thompson, can be presented as evidence at his trial. The decision, delivered on Monday by Judge Gregory Carro, represents a significant victory for prosecutors, allowing them to show the jury a potential murder weapon and evidence they claim indicates motive. This ruling aligns with a previous decision in Mangione's federal case.
Key Evidence and Legal Arguments
Judge Carro's ruling came after a five-month review of how police obtained the items. The defense had argued that the evidence was seized illegally, prior to the acquisition of a search warrant. However, the judge determined that the gun and notebook were admissible. Notably, the judge did order that evidence found during an initial search of Mangione's backpack at the time of his arrest—including a gun ammunition magazine, cellphone, passport, wallet, and computer chip—must be suppressed.
The state murder trial is scheduled to begin on September 8, with jury selection for the federal trial, which involves stalking charges, starting on October 13. Opening statements and testimony in the federal case are set for November 4. The state trial is expected to last between four and six weeks. Mangione, 28, has entered not guilty pleas in both cases and faces the possibility of life imprisonment if convicted in either.
Details of the Arrest and Evidence
Police discovered the gun, notebook, and other items in Mangione's backpack after he was spotted eating breakfast at a McDonald's restaurant in Altoona, Pennsylvania, on December 9, 2024, five days after Thompson was fatally shot outside a Manhattan hotel. Altoona is located approximately 230 miles (370 kilometers) west of Manhattan.
Prosecutors allege that the gun, a 3D-printed pistol, matches the weapon used to kill Thompson. The notebook, described by prosecutors as a "manifesto," contains references to wanting to "wack" a health insurance executive and rebelling against "the deadly, greed fueled health insurance cartel."
Mangione's legal team contended that the search was unlawful, arguing that police officers examined the backpack before obtaining a warrant. In response, prosecutors maintained that the search was legal because it was conducted in conjunction with an arrest and followed Altoona police protocols requiring officers to check for dangerous items that could pose a threat to themselves or the public. A warrant was eventually obtained, prosecutors added.
Background of the Case
Surveillance footage captured a masked gunman shooting Thompson from behind on December 4, 2024, as he walked to his company's annual investor conference at the New York Hilton Midtown. Police reported that the words "delay," "deny," and "depose" were inscribed on the ammunition, mimicking a phrase commonly used to describe how insurers avoid paying claims.
During a three-week hearing in December, Altoona police officers provided testimony on how they conducted Mangione's arrest and searched his backpack. Prosecutors also played body-worn camera footage of the arrest in court for the first time, with some clips later made public. Judge Carro had indicated he would review the body-camera video before reaching a decision.
According to testimony and video evidence, officers began searching the bag at the McDonald's but stopped after discovering a loaded gun magazine wrapped in a pair of underwear. This finding appeared to confirm their suspicions that Mangione was the wanted man. "It's him, dude. It's him, 100%," Officer Stephen Fox said on the video, punctuating the remark with expletives as Officer Christy Wasser held up the magazine.
Officers continued searching the bag at the police station, where they found the gun and silencer. They then conducted an inventory search, cataloging all seized property, which uncovered the notebook and other notes, including what appeared to be to-do lists and possible getaway plans. Prosecutors argued that this search was also required under Altoona police policy. The judicial warrant was obtained hours later.
Laws governing how police obtain search warrants are complex and frequently contested in criminal cases. Prosecutors have extensively quoted from Mangione's handwritten diary in court filings, including his praise for Unabomber Ted Kaczynski.
