Luigi Mangione, the man accused of assassinating a health insurance executive in a carefully executed plot, could have a hard time convincing jurors at his murder trial that he suffered a mental health breakdown, legal experts have said.

Mangione is accused of fatally shooting UnitedHealthcare CEO Brian Thompson outside a hotel ?in Midtown Manhattan in December 2024. Defense lawyers indicated on Wednesday that Mangione plans to mount a type of legal defense ?that allows ?jurors to downgrade murder charges to manslaughter if they believe a defendant lost control of their ?actions due to an ¡°extreme emotional disturbance.¡±

But allegations that Mangione meticulously planned the assassination and concealed his identity as he led law enforcement on a five-day manhunt could cut against an argument that he lost control of his actions, according to former Manhattan state ?prosecutor Gary Galperin.
