Luigi Mangione allegedly laid out his plot to kill UnitedHealthcare CEO Brian Thompson in a spiral notebook, including a chilling “to-do list” and plans considering using a bomb in the Manhattan attack.
The notebook was found alongside a 262-word manifesto, a ghost gun, silencer and false ID cards in the shooting suspect’s possession at the time of his arrest at a McDonald’s in Altoona, Pennsylvania, Monday, according to CNN.
