Did Mangione’s assassin video game past hint at CEO's murder?

Former Ivy League student Luigi Mangione, 26, has been arrested for the murder of United Healthcare CEO Brian Thompson. Mangione, who played the online game "Among Us," was found with a 3D-printed firearm and a manifesto. His online activity post-graduation, including engagement with the Unabomber Manifesto, is under scrutiny as police investigate his motives.
