Luigi Mangione's legal team on Thursday withdrew its intention to invoke a psychiatric defense in the state trial over the killing of UnitedHealthcare CEO Brian Thompson.
The Manhattan district attorney's office said the Altoona police officers acted "in deliberate and painstaking fashion" when they arrested Mangione in a McDonald's and complied with Pennsylvania search-and-seizure law.
Federal prosecutors in New York signaled in a letter to the court Friday that they would not appeal a judge's decision that removed the death penalty from consideration in the case against Luigi Mangione.
Mark Anderson, 36, allegedly went to the Metropolitan Detention Center in Brooklyn on Jan. 28 posing as a federal agent and claimed to have a court order to release Mangione.
Luigi Mangione's state murder case is tentatively scheduled to begin on June 8, Judge Gregory Carro said on Friday.
Luigi Mangione has been called to court on February 6. The summons notification did not include a reason for the unexpected court appearance.
