An Indiana appellate court heard Richard Allen's appeal of his 130-year sentence on September 21, 2026, after his November 2024 conviction for the 2017 Delphi murders of Libby German and Abby Williams. The defense argues solitary confinement induced psychosis and a false confession, and says the prosecution admitted Allen was psychotic when he confessed and described shootings that did not match the victims' wounds. It also challenges the exclusion of a defense cartridge expert and a police sketch of another suspect, lost recordings of early Odinist suspects, and a bullet comparison that initially failed. The state maintains the confessions were voluntary. Jurors have since said their first vote was three undecided, never not guilty.
