In 2024, Luigi Mangione allegedly shot UnitedHealthcare CEO, aiming to target the health insurance industry, prosecutors say.

Luigi Mangione, 27, is accused of killing UnitedHealthcare CEO Brian Thompson in December. Prosecutors claim Mangione's diary shows he wanted to target the health insurance industry, calling it a "greed-fueled cartel." The diary also mentions admiration for the Unabomber. Mangione faces state and federal charges, with prosecutors using his writings to uphold the state charges, while his lawyers argue for double jeopardy. Mangione has pleaded not guilty in both cases.
