Answer Key

1. Brian Thompson was the CEO of UnitedHealthcare, America’s largest healthcare company. He was shot and killed on a Midtown Manhattan sidewalk outside the New York Hilton Midtown hotel on December 4, 2024, while in the city for an annual investors' meeting. The words "delay," "deny," and "depose" were written on the spent ammunition casings found at the scene.

2. Mangione was arrested on December 9, 2024, at a McDonald's in Altoona, Pennsylvania, following a five-day nationwide manhunt. A restaurant manager called 911 after customers noted his resemblance to the suspect's police description. Police reported that Mangione was "visibly shaken" when they approached him.

3. Upon his arrest, police reported finding a 3D-printed gun and a 3D-printed suppressor similar to the weapons used in the shooting. They also found a fake New Jersey driver's license with the name "Mark Rosario" and a 262-word handwritten document.

4. The handwritten document, addressed "To the Feds," states that the author acted alone and details motivations related to the U.S. healthcare system. It cites the high cost of care versus lower life expectancy and references critics of the industry like Michael Moore and Elisabeth Rosenthal. The document is seen by authorities as speaking to Mangione's "motivation and mindset."

5. Corrections officer Thomas Rivers testified that Mangione was placed under constant watch, a measure typically for suicidal inmates, because the facility's supervisor "did not want [a Jeffrey] Epstein-style situation." This was to ensure his security and prevent him from dying in custody.

6. Mangione and Rivers had wide-ranging conversations that included the difference between private and nationalized healthcare, literature by authors like George Orwell and Henry David Thoreau, and the Unabomber, Ted Kaczynski. Mangione also reportedly expressed disappointment that online commenters were comparing him to Kaczynski.

7. The goal of the suppression hearing is for Mangione's lawyers to bar prosecutors from using key evidence in his state trial. The defense argues that items seized from his backpack, including the alleged murder weapon and a notebook, were obtained through a warrantless search and that statements he made to police were given before he was read his rights.

8. The four federal charges against Mangione are two counts of stalking, murder through the use of a firearm, and a general firearms offense. U.S. Attorney General Pam Bondi announced that prosecutors would seek the death penalty in his federal case.

9. Polls indicate a mixed and polarized public opinion. An Economist/YouGov poll found 43% of American citizens held an unfavorable view of Mangione versus 21% favorable. Support was notably higher among younger (18-29) and more liberal respondents, while older and more conservative individuals viewed him unfavorably.

10. The "good faith" exception prevents the suppression of evidence that was acquired by officers through an unlawful search or seizure if the mistake was made by a non-law enforcement government employee (like a judge or court clerk) and the officers reasonably believed they were acting lawfully. The exception focuses on the objective reasonableness of the officers' actions, not their subjective "good faith."
