A significant evidentiary struggle took place in a Manhattan courtroom on Monday as prosecutors, for the first time, presented the complete 911 call and surveillance footage that resulted in the arrest of Luigi Mangione, who is accused of killing UnitedHealthcare CEO Brian Thompson. This set the stage for a high-stakes hearing that could influence what evidence the jury ultimately sees.
Mangione, 27, reportedly appeared highly focused throughout the day’s proceedings. He leaned forward, took notes, and watched without showing any visible reaction as prosecutors presented a series of videos to the judge. These included footage of the Midtown shooting, images of the suspect that circulated online last year, and previously unseen footage of Mangione’s arrest on December 9, 2024, inside a McDonald’s in Altoona, Pennsylvania.
THE 911 CALL THAT SPARKED THE ARREST
The centerpiece of Monday’s session was the prosecution’s dramatic decision to play the entire 911 call made by a McDonald’s manager who recognized Mangione from police bulletins.
“I have a customer here that… looks like the CEO shooter from New York,” the manager said on the muffled recording, telling the dispatcher that patrons were becoming “really upset,” per ABC. Identifying him only by a black jacket, surgical mask, and tan beanie, the manager admitted the only visible facial feature was “his eyebrows.”
Mangione listened silently, occasionally jotting down notes.
DEFENSE: ILLEGAL ARREST, ILLEGAL SEARCH
The day was dominated by the defense’s attempt to exclude nearly all evidence found on Mangione at the time of arrest, including a 3D-printed handgun, ammunition, and a notebook in which prosecutors say he laid out a motive aimed at the health-insurance industry.
Defense attorneys argued officers in Altoona questioned Mangione for around 20 minutes before reading Miranda rights, boxed him in with an “armed human wall,” and searched his backpack despite an officer on body-camera acknowledging they likely needed a warrant.
One Altoona officer testified she kept searching because she wanted to ensure there “wasn’t a bomb” in the bag, a claim the defense called a “made-up excuse” meant to justify an unconstitutional search.
CORRECTIONS OFFICERS TESTIFY: ‘EPSTEIN-STYLE SITUATION’
Two Pennsylvania corrections officers reportedly told the court that after his arrest, Mangione was held in an isolated unit under constant supervision to prevent an “Epstein-style situation.” One officer, Tomas Rivers, recounted conversations with Mangione about health care systems and travel abroad; another testified Mangione spontaneously mentioned possessing a 3D-printed gun, a statement the defense cast doubt on.
PROSECUTORS PUSH TO CONFIRM IDENTITY, MOTIVE
Prosecutors countered by showing footage of the suspect approaching Thompson and firing multiple rounds, then calmly walking away. Additional images showed the suspect at a Starbucks, on a bicycle, in a taxi, and checking into a Manhattan hostel under the name “Mark Rosario,” the same name Mangione allegedly gave police during his arrest.
They also reportedly argued that even if the backpack search is ruled illegal, much of the evidence would have been uncovered through standard investigative steps.
THE STAKES
This week’s suppression hearing will determine whether prosecutors can use:
- the alleged murder weapon
- a loaded magazine
- electronic devices
- foreign currency
- Mangione’s handwritten journal entries, prosecutors say, outline anti-insurance rhetoric, praise for Ted Kaczynski, and an intent to “wack” an insurance executive
If Judge Gregory Carro suppresses these items, it would be a blow to the prosecutors’ murder case.
Earlier this year, Carro scrapped the terrorism charges facing Mangione, The Dallas Express reported.
Nearly two dozen Mangione supporters attended Monday’s hearing, some wearing shirts declaring “Justice is not a spectacle.”
The hearing resumes on Tuesday and is expected to continue for several days.
