Once Luigi Mangione, the suspect in the fatal shooting of UnitedHealthcare CEO Brian Thompson, was finally located, the moment didn’t unfold in a dramatic chase or cinematic takedown. Instead, it happened quietly inside a dimly-lit McDonald’s in Altoona, Pennsylvania — an unexpectedly mundane setting for the arrest that is now at the center of a tense, multi-day hearing over what evidence will be allowed at trial. What began with a calm 911 call has now evolved into a legal battle that could determine how the case moves forward.

The 911 Call That Set Everything in Motion
The turning point came on the morning of December 9, 2024, when a McDonald’s manager phoned 911 after concerned customers approached her. Her voice was steady, even as she described their fears that the man sitting alone near the restaurant bathrooms looked exactly like the individual wanted in the Manhattan shooting.
“I have a customer here that some other customers were suspicious of and he looks like the CEO shooter from New York,” she told the dispatcher.
She described him with precision — black jacket, tan beanie, medical mask that revealed only his eyebrows, and a pharmacy bag placed on the table in front of him.
She noted that she had tried calling the nonemergency line first but couldn’t get through. The dispatcher confirmed an officer was already on the way. It was a quiet beginning to what would become one of the most scrutinized arrests of the year.
“I Knew It Was Him Immediately”
Altoona Police Officer Joseph Detwiler testified that he didn’t initially believe the tip — even joking with a supervisor about being bought a hoagie if it turned out to be the right person. But the joking stopped the moment he walked inside.
He approached the man at the table and asked him to pull his mask down. The instant he did, Detwiler said, “I knew it was him immediately.” Though the approach was casual, the tension was unmistakable. Given the nature of the crime, Detwiler testified he was alert to potential danger: “After he pulled his mask down, I knew that there was a safety issue possibly for us.”
Mangione had been frisked early in the encounter, but Detwiler said he only learned the suspect had a knife when Mangione disclosed it nearly 20 minutes later. The suspect had also given police a false name before they contacted prosecutors in New York for confirmation.
As officers prepared to read his Miranda rights, holiday music floated through the speakers — and as “I’ll Be Home for Christmas” played overhead, Mangione was handcuffed, having just finished his breakfast.
What They Found — and What the Defense Wants Suppressed
Prosecutors presented photos showing items taken from Mangione: multiple wallets, his medical mask, a Sharpie marker, and more than $7,000 in cash. His attorneys are arguing that his early statements to police — along with writings and a gun found in his backpack — should all be excluded from trial. They claim these items were obtained before officers secured a proper search warrant.
Judge Gregory Carro has sealed all body-worn camera footage for now. “At this time I will seal every exhibit,” he said, explaining that the materials fall under the suppression hearing and shouldn’t be released until rulings are made.
Inside Mangione’s Time at SCI Huntingdon
Two corrections officers testified about their interactions with Mangione while he was held at SCI Huntingdon. Officer Matthew Henry said the suspect told him he had a backpack containing foreign currency, a 3D-printed gun, and a magazine of ammunition — though Henry acknowledged he never wrote this down until questioned a month later by the Manhattan District Attorney’s office. Defense attorney Marc Agnifilo challenged his credibility, asking whether Mangione simply “blurted” these details out or whether Henry was influenced by news reports.
Another officer, Tomas Rivers, monitored the suspect for long hours and said he had been told the prison did not want “an Epstein-style situation.” Rivers described Mangione as talkative, frequently standing near his cell door to discuss topics ranging from nationalized healthcare to global medical systems. He also said they spoke about media coverage of the case — noting that traditional outlets focused on the crime itself while social media circulated broader conspiracy-style discussions about the healthcare industry.
The Video Trail
Prosecutors also outlined how investigators used surveillance footage to trace the suspect’s movements across Manhattan and eventually to Altoona. Cameras captured everything from the shooting on the sidewalk to glimpses of the suspect in a Starbucks, hostel, and taxi.
Inside McDonald’s, footage showed Mangione ordering food, walking to a corner table, and sitting alone for about 25 minutes before officers approached. By the time he was in custody, eight officers had converged on the scene. There was no audio on any of the videos.
What Comes Next
As the hearing continues, the stakes remain high. Mangione’s legal team is attempting to toss out all statements he made from the moment of his arrest on December 9 through December 19, when he was transported to New York. With the outcome still uncertain, one thing is clear: a quiet morning at McDonald’s has spiraled into a complex evidentiary showdown — and the name Mangione will continue to dominate every development as the case moves closer to trial.
