State of Louisiana vs. Jimmie C. Duncan, 2025-KP-01014

Duncan was convicted of first degree murder for the death of 23-month-old Haley Oliveaux and sentenced to death, and his conviction was affirmed on direct appeal. 1
At trial, the State theorized Duncan bit Haley, sexually assaulted her, and forcibly drowned her, while the defense argued she drowned after a seizure in the bathtub. 2
The State's case relied heavily on bite-mark and forensic pathology testimony from Drs. Hayne, West, Riesner, and Gustavson, plus jailhouse informant Michael Cruse. 3
In post-conviction proceedings, Duncan presented new expert and documentary evidence undermining the bite-mark, sexual-assault, drowning, and confession evidence. 4
After a six-day hearing, the trial court granted factual-innocence and ineffective-assistance relief, vacated the conviction and death sentence, and the State sought writ review. 5
The Supreme Court of Louisiana affirmed, holding Duncan met article 926.2's clear-and-convincing factual-innocence standard. 6

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did Duncan present qualifying new evidence under article 926.2? 7	Duncan said post-trial scientific and documentary evidence was new and reliable.	The State said much was merely impeachment and not qualifying new evidence.	Yes; Carrington's corroborated evidence satisfied article 926.2(B)(1)(a). 8
Did the new evidence prove no rational juror would convict? 9	Duncan argued the evidence destroyed the State's bite-mark, rape, and drowning theories.	The State argued the proof was still sufficient overall.	Yes; the court found the State's core theory was substantially undermined. 10
Was the trial court's grant of factual-innocence relief an abuse of discretion? 11	Duncan contended the trial court correctly weighed the new evidence.	The State contended the trial court erred in granting relief.	No; the court affirmed the relief and vacatur. 12
Should the court decide Duncan's ineffective-assistance claim? 13	Duncan also sought relief for ineffective assistance.	The State opposed that additional basis for relief.	No; the court pretermitted that claim after affirming factual-innocence relief. 14
