Federal Criminal Procedure and Death Penalty

Judge Gregory Carro set the New York state murder trial for June 8, 2026 (with a Sept. 8 fallback if a federal appeal delays proceedings), telling defense to be ready as Luigi Mangione — accused in the 2024 killing of UnitedHealthCare CEO Brian Thompson — protested the scheduling as “double jeopardy.” Federal Judge Margaret M. Garnett has ruled Mangione ineligible for the death penalty, ordered an Altoona officer to testify as the defense seeks suppression of backpack evidence (including a 3D‑printed handgun, magazine, notebook and alleged anti‑insurance writings), demanded the affidavit supporting the federal search warrant, and prosecutors say the items would have been inevitably discovered.
