Luigi Mangione to assert psychiatric defense in murder trial
A New York judge said Wednesday that Luigi Mangione will assert a psychiatric defense in his trial in the 2024 killing of United Healthcare CEO Brian Thompson.

TL;DR
- Luigi Mangione will assert a psychiatric defense in his trial for the killing of United Healthcare CEO Brian Thompson.
- The defense will argue Mangione was suffering from "extreme emotional disturbance" at the time of the killing.
- Success with this defense could result in Mangione being sent to a psychiatric treatment facility instead of prison.
- New York law requires defendants to pass three tests to establish an extreme emotional disturbance defense.
- These tests include demonstrating a profound loss of self-control, an objectively reasonable explanation for the disturbance, and the homicide being committed under its influence.
- Mangione faces state and federal charges, but the psychiatric defense is only applicable in state court.
- Prosecutors stated Mangione was not insured by UnitedHealthcare and his alleged notebook expressed hostility towards the health insurance industry.
