A Pennsylvania police officer testified Monday that bullets wrapped in damp underwear were discovered inside the backpack of Luigi Mangione, the man accused of fatally shooting UnitedHealthcare CEO Brian Thompson on a Midtown Manhattan street last year, as reported by the New York Post.

The testimony came during an evidence suppression hearing in Manhattan Supreme Court, where prosecutors also revealed handwritten notes and checklists allegedly recovered from Mangione’s belongings.
Officer Christy Wasser of the Altoona Police Department testified that she opened a pair of gray Hanes underwear found in Mangione’s bag following his Dec. 9, 2024, arrest at a McDonald’s in Altoona.

This Could Be the Most Important Video Gun Owners Watch All Year
“When I opened it up, it was a magazine,” Wasser said, adding that the magazine was fully loaded. Body camera footage played in court captured another officer reacting to the discovery, saying, “Damn dude, it’s f–king him – 100%.”
Mangione, 27, was taken into custody five days after Thompson’s killing. Authorities also conducted a second search of his belongings at the police station, where additional items were documented.
Manhattan Assistant District Attorney Joel Seidemann said investigators recovered handwritten notes that included a reminder to “pluck eyebrows” and listed several cities in Ohio, including Columbus, Cleveland, and Cincinnati. Photos released by prosecutors showed tweezers among the contents of the backpack.
Prosecutors also presented a hand-drawn map of Pittsburgh, approximately 100 miles from Altoona, that showed possible escape routes.
Pictures of Luigi Mangione’s red notebook and to-do list dated Dec 5 have been released.

Another note, styled as a checklist, included the instructions “Check Pittsburg redeyes,” “keep momentum,” and “FBI slower overnight.”
The gun allegedly used to kill Thompson, a silencer, and a red notebook described as Mangione’s manifesto were also recovered, according to testimony.
A photo of the notebook was displayed in court during the fourth day of the pre-trial hearing.
The defense is seeking to block several pieces of evidence, including the firearm, arguing that the Altoona officers did not have a warrant when they discovered the materials.
Prosecutors maintain the searches were lawful.
Wasser, a 19-year police veteran, testified she checked the bag because she did not want to “pull a Moser,” referencing an incident involving a former officer who unknowingly transported a bomb back to the station.
She said she routinely searches the bags of individuals placed under arrest.
Authorities testified that some evidence—such as a hoagie and a laptop—was placed into a McDonald’s bag before officers transported Mangione to the station.
Additional photos released by prosecutors over the weekend showed a checklist detailing a planned trip to Best Buy with items such as a USB 256 flash drive, digital camera, and light source dated Dec. 8.
The note also included “Hot meal + water bottles,” trash bags, “Intel check in,” and “survival kit” listed under “Future TO DO.”
Prosecutors also displayed items recovered at the time of the arrest, including a small flashlight, a USB drive attached to a silver necklace, a pocket knife, and thousands of dollars in $100 bills.
Mangione also had a bus ticket under the name “Sam Dawson” for travel from Philadelphia to Pittsburgh on Dec. 4, 2024—the same day Thompson was shot. It remains unclear who purchased the ticket.
Mangione appeared in court on Monday after missing Friday’s session due to illness. Before proceedings began, he briefly flashed a fist pump toward the camera while seated at the defense table with his attorney, Karen Friedman Agnifilo.
Mangione has pleaded not guilty in both the Manhattan case and an unrelated federal matter. The hearing is scheduled to resume on Tuesday.
Luigi Mangione returned to court this week as prosecutors played surveillance footage of the kill*ng of Brian Thompson, the CEO of UnitedHealthcare.
