Luigi Mangione's full arrest and strip search seen on newly released bodycam footage

New bodycam footage showed the moment Luigi Mangione was questioned inside a Pennsylvania McDonald's and strip-searched after killing UnitedHealthcare CEO Brian Thompson in Manhattan. In one video, officers ask Mangione to lower the face mask he was wearing to hide his identity.'That's 100 percent him,' one officer eagerly said as they stepped outside to speak out of Mangione's earshot.'I told you, man,' another responded off camera.Later, an officer searched Mangione's belongings and smiled widely as she pulled out a gun cartridge, seemingly confirming they found their suspect.The trove of videos comes from Mangione's December 9, 2024, arrest in Altoona, five days after Thompson, a 50-year-old Minnesota executive, was gunned down as he walked to a midtown Manhattan hotel for his company's annual investor conference.A Manhattan judge unsealed the recordings on Friday after CNN petitioned for their release. Parts of the videos were shown during a December court hearing as Mangione's lawyers unsuccessfully sought to get key evidence thrown out, including his initial statements to police and items seized at the time of his arrest.

The officers say they're responding to a call about a suspicious person and ask for his name and identification.'You're a little nervous right now. Why are you nervous?' an officer asks at one point.They order him to put his hands on his head and ask him if he's been in New York recently. They confront him about a phony New Jersey driver's license he offered up bearing the name Mark Rosario.'You're under official police investigation right now,' one officer warned. 'You give a false name to us again, you're gonna be arrested for false ID.'When Mangione finally came clean, they asked why he had lied.

They also recovered the journal that prosecutors would later say revealed Mangione's intent to 'whack' a health insurance executive, as well as his other handwritten notes.'He has a checklist for today,' another officer said, ticking off the seized items to someone on the phone.

I observed that the annual conference of America's largest health care organization and the stated mission to make health – excuse me – with the stated mission to make the health system work better for everyone, would be attended by company executives, the board of directors, and hundreds of investors, not doctors, nurses, and patients.'Mangione went on to reveal how he got Thompson's location and acquired the murder weapon.He said: 'In November of 2024, I traveled from outside of New York State to Manhattan. I then emailed UnitedHealthcare leadership posing as an investor at a firm managing over $50 billion in assets and requesting information about the conference.'Unlike my previous interactions with insurers, I received an immediate response within an hour. Before traveling to New York, I used a 3D printer to make part of a gun, and I equipped the gun with the silencer and magazine. My travel to New York and email to UnitedHealthcare was with the intent to shoot Brian Thompson.'Mangione concluded: 'On the morning of December 4, 2024, I shot Mr Thompson in Manhattan and he died. When I did so, I understood that my actions would place him in fear of death or serious bodily injury. I knew what I was doing was illegal.'The federal stalking charges he admitted to carry a maximum sentence of life in prison.His sentencing hearing has been scheduled for December 18.The Daily Mail reached out to Mangione's attorney for comment.
