The U.S. Court of Appeals for the 8th Circuit has rejected the latest appeal from Briley Piper, a South Dakota State Penitentiary offender sentenced to the death penalty. In a ruling filed on Monday (May 4, 2026), the court affirmed the United States District Court for the District of South Dakota’s denial of Briley Piper’s petition for habeas corpus relief.
“Today, the 8th Circuit Court of Appeals affirmed Piper’s death sentence for ‘the extended and brutal nature of the murder’ of Chester Poage,” said Attorney General Marty Jackley. “Briley Piper has never accepted responsibility for his actions and has consistently tried to shift blame onto others for his sentence. The 8th Circuit’s rejection of his appeal marks an important step toward final justice for Chester Poage and his family.”
Piper had previously pled guilty in 2001 to multiple charges, including first‑degree felony murder, connected to the March 2000 killing of Chester Allan Poage in Lawrence County. A state court originally imposed a death sentence, which was later vacated by the South Dakota Supreme Court. After a jury resentencing, the death sentence was reimposed and upheld on appeal.
The 8th Circuit reviewed six issues on appeal, including: the constitutionality of federal habeas corpus review standards under the Antiterrorism and Effective Death Penalty Act (AEDPA); the application of South Dakota’s res judicata doctrine to Piper’s challenge to his guilty pleas: whether an evidentiary hearing was required regarding mitigating mental‑health evidence; whether trial counsel adequately investigated and presented impeachment evidence regarding witness testimony; issues related to testimony about alleged prison‑rule violations; and, a claim of cumulative prejudice. The 8th Circuit rejected each of Piper’s claims.
