Mary Mangione's said she didn't want anything to go to a "lineal descendant" who is "charged, indicted, convicted of or pleads guilty to a felony."

Luigi Mangione yelled to the press about "an insult to the intelligence of the American people" as he was physically dragged into a Pennsylvania courthouse.

In his notebook, Mangione deliberated: "What do you do? You wack the CEO at the annual parasitic bean-counter convention. It's targeted, precise, and doesn't risk innocents," It's not yet known how he got the gun and how he got the specific timing of Brian Thompson's arrival at the hotel where he executed what he considered a mission.

Mangione, 26, was arrested on Monday and charged with the murder of UnitedHealthcare's chief executive Brian Thompson.
