Luigi Mangione will assert psychiatric defense in murder case in UnitedHealthcare CEO’s killing

Luigi Mangione will use an extreme emotional disturbance defense in his state murder trial for killing UnitedHealthcare CEO Brian Thompson, which could result in a manslaughter conviction with up to 25 years in prison instead of a potential life sentence for murder. Judge Gregory Carro confirmed the defense strategy, which is not available in Mangione's separate federal trial, and stated the state trial is set to begin on September 8.
