Luigi Mangione's high-stakes court hearing in New York resumed Thursday, exactly one year after prosecutors say he murdered UnitedHealthcare CEO Brian Thompson in Manhattan. 

The focus of the hearing returned to the 27-year-old suspect's interaction with police officers who arrested him five days after the shooting at a McDonald's in Altoona, Pennsylvania. 

Mangione's lawyers claim certain evidence, including a gun, notebook, and FBI note, should not be allowed in the state trial because they say he was not read his Miranda rights before questioning and that his backpack was searched without a warrant. 

Photographic evidence in the case was also released, providing the public a first look at some imagery from the case they may not have seen before. 

In court, photos of bus tickets taken during a search of Mangione's pockets were displayed, dated Dec. 4, 2024, the day of the shooting. One of the tickets for Drexel station at 1:06 p.m. Another reads Philadelphia to Pittsburgh, 11:55 p.m. The name on the ticket is Sam Dawson, and it lists one stored and one carry-on bag.   

A folded-up note also found in one of his pockets is a checklist, of sorts. It includes the date, 12/8, and Best Buy, USBs, digital cam, water bottles and trash bag. 

Mangione also turned over a silver chain he was wearing with a USB on it. Video shows Mangione removing the three layers of clothing he was wearing to be searched, and him giving his mother as his emergency contact. 

Second officer testifies about Mangione's arrest at McDonald's

Testimony picked up Thursday morning in Manhattan Superior Court as prosecutors called to the stand Patrolman Tyler Frye, another officer who responded to the Altoona McDonald's, where the manhunt for Mangione came to an end in December 2024.

Frye's interactions with Mangione at the McDonald's were shown on police body camera video played in court, including after Mangione presented an ID for "Mark Rosario." On the video, after telling officers his real name, Mangione tells Frye he lied because "that was the ID I had in my wallet."

Frye testified when officers approached Mangione, they asked him basic questions like where he was from and why he was in Altoona.  

Mangione is seen on bodycam being told he's under investigation, and is told if he gives police another false name he'll be arrested. Mangione was not read his Miranda rights after being warned about the possible false ID arrest. 

The defense argued the way officers were positioned, as seen on body camera, suggested was not free to leave at first, although Frye testified there was some room for Mangione to get up and leave. 

Another patrolman asked Mangione why he lied about his identity. 

"I clearly shouldn't have," Mangione said. 

The video shows officers frisking Mangione and moving his backpack off to the side before detaining and ultimately arresting him on a fake ID charge. After taking Mangione into custody, video shows an officer reading his Miranda rights, patting him down and placing him in handcuffs. 

According to Frye, Mangione's backpack was first searched after he was arrested, a procedure the officer called "very common." 

The defense argues officers didn't have a search warrant and evidence from the bag, like a ghost gun, shouldn't be allowed at trial. 

When officers called for backup, Mangione is heard saying, "Can I ask why there are so many cops here?" Another officer tells him they're "just trying to figure it out." 

Frye said they then took Mangione back to the police station in a marked car. During the ride, Frye said Mangione asked the officers for their names and apologized for the inconvenience at McDonald's. Frye said he told Mangione, "The fake ID was a bit ridiculous." 

At the station, officers performed an in-depth search of Mangione. Frye testified that after the search an officer removed Mangione's necklace, which he said held a USB drive that was put into evidence.

Another officer also noted a gun in Mangione's backpack, according to the video. 

The video shows police continuing to question Mangione about his background and escorting him to a cell. 

Frye testified he agreed that Mangione was not combative and caused no safety concerns the entire time he was in their custody that day. 

The defense pointed out Mangione didn't reach for the backpack or try to open it, and that it was Mangione who alert police to the fact that he had a pocket knife after he was initially searched. 

Mangione's defense asked Frye if prosecutors had previously gone over their questions with him, prior to his taking the stand. Frye said yes, they had been over that several times over several days. 

Police bodycam played in court

Officer Joseph Detwiler, who responded to the McDonald's 911 call with Frye, testified about the interaction on Tuesday, when the bodycam video was first played in court. It shows officers had interacted with Mangione for roughly 20 minutes before telling him he had the right to remain silent. The officers asked his name, whether he'd been in New York recently, and other questions, including: "Why are you nervous?"

The officers tried to play it cool and buy time by intimating that they were simply responding to a loitering complaint and chatted about his steak sandwich. Still, they patted Mangione down and pushed his backpack away from him. About 15 minutes in, they warned him that he was being investigated and would be arrested if he repeated what they'd determined was a fake name.  

Detwiler had testified he responded without his lights or sirens on because, "I didn't think it was gonna be him." He said his lieutenant even joked that if he caught the New York City shooter, the lieutenant would buy him a hoagie.  

Detwiler said that he asked the man in the restaurant to lower his mask and, "I knew it was him immediately." 

Mangione's lawyers say his statements should not be allowed as evidence

Mangione's lawyers argue that his statements should not be allowed as evidence in the trial because officers started questioning him before reading his rights. The defense also contends the backpack items should be excluded because police didn't get a warrant before searching his bag.

The evidence is key to prosecutors' case. They have said that the 9 mm handgun matches the firearm used in the killing of Thompson, that writings in the notebook laid out Mangione's disdain for health insurers and ideas about killing a CEO at an investor conference, and that he gave Pennsylvania police the same fake name that the alleged gunman used at a New York hostel days before the shooting.

Manhattan prosecutors have not yet detailed their arguments for allowing the disputed evidence. Federal prosecutors have maintained that police were justified in searching the backpack to ensure there was nothing dangerous inside and that Mangione's statements to officers were voluntary and made before he was under arrest.

Many criminal cases see disputes over evidence and the complicated legal standards governing police searches and interactions with potential suspects.

Mangione pleaded not guilty to state and federal charges in connection with Thompson's killing. He is being held at the Metropolitan Detention Center in Brooklyn as he awaits trial. 

Thompson, 50, was shot from behind as he walked to an investor conference on Dec. 4, 2024. He became UnitedHealthcare's CEO in 2021 and had worked within parent UnitedHealth Group Inc. for 20 years.
