NEW YORK (AP) — Six weeks before UnitedHealthcare CEO Brian Thompson was gunned down outside a Manhattan hotel in December, suspect Luigi Mangione mused about rebelling against “the deadly, greed fueled health insurance cartel” and said killing the executive “conveys a greedy bastard that had it coming,” prosecutors revealed Wednesday.

His defense lawyer, Karen Agnifilo Friedman, requested that the top charge be dropped because, she said, it should not be applied to the death of a single person. The Manhattan District Attorney filed an 82-page brief opposing Luigi Mangione's effort to drop his terrorism charges.

Luigi Mangione reportedly mapped out his thought process before allegedly killing UnitedHealthcare CEO Brian Thompson in a journal found on his person during his detainment.
