Luigi Mangione, 28, Mounts Psychiatric Defense in Brian Thompson Murder Trial

Summary
Justice Gregory Carro said Luigi Mangione’s lawyers will argue he was under “extreme emotional disturbance” when prosecutors say he fatally shot UnitedHealthcare CEO Brian Thompson in December 2024.
Carro said he will unseal records tied to that psychiatric defense, despite objections from Mangione’s lawyer that disclosure could affect his separate federal case.
The judge also dismissed one charge tied to possession of a large-capacity ammunition magazine after ruling in May that some items from an initial backpack search must be suppressed.
Other evidence from a later backpack search — including a gun and a red notebook that prosecutors say explains why Thompson was targeted — can still be used at the New York state trial expected in September.
Mangione was arrested after a five-day manhunt and still faces nine felony counts in New York, plus separate cases in Pennsylvania and federal court.
