Former Louisiana death row inmate Jimmie "Chris" Duncan is officially a free man following a unanimous ruling Monday by the Louisiana Supreme Court. In the opinion, justices upheld a lower court's decision to toss out Duncan's 1998 conviction for killing his former girlfriend's toddler, Haley Oliveaux, citing flawed forensics practices used to convict him.
Duncan was convicted based largely on now-discredited bite mark evidence presented by forensic dentist Michael West and pathologist Steven Hayne. Their analysis claimed to match marks on Haley's body to Duncan's teeth. Justice Cade R. Cole wrote on behalf of the seven-member court that new evidence presented by Duncan's legal team left no doubt his conviction should be overturned.
"The post-conviction evidence undermined the core factual premises on which the state depended," Cole wrote in the official opinion. The ruling came after a 2025 Verite News and ProPublica investigation examined the reliability of the key forensic evidence used to convict Duncan, now 57 years old.
What the Right Is Saying
Conservative legal commentators noted the court's careful language about maintaining the integrity of death penalty proceedings rather than questioning capital punishment itself. Chief Justice John Weimer wrote in a concurrence that while he agreed with the ruling, the case demonstrated why courts must be "extremely careful" in death penalty cases due to their finality.
Louisiana Governor Jeff Landry, a staunch death penalty advocate who had made moves to expedite executions after a 15-year pause, has not issued a public statement on the ruling. The governor's office did not respond to requests for comment as of publication time.
Some law enforcement supporters expressed concern about setting aside convictions years after trials concluded, arguing that juries heard the evidence presented to them at the time and rendered verdicts based on available information. Defense attorneys counter that the entire purpose of post-conviction review is to apply updated scientific standards to historical cases.
What the Left Is Saying
Criminal justice reform advocates praised the ruling as a landmark moment for wrongful conviction cases. Chris Fabricant, a member of Duncan's legal team and director of strategic litigation with the Innocence Project in New York, said in an interview: "I am flooded with relief. It would have been a moral outrage for the conviction to be reinstated."
The Innocence Project argued that the case exemplifies systemic failures in forensic science practices accepted by courts decades ago. In the 28 years since Duncan's trial, nine other prisoners have been set free after being convicted in part on inaccurate evidence given by West and Hayne. Three of those men were on death row.
Civil rights attorneys have long argued that bite mark analysis lacks scientific validity and has contributed to numerous wrongful convictions nationwide. The American Board of Forensic Odontologists has acknowledged limitations in the discipline's reliability for matching marks to specific individuals.
What the Numbers Show
According to court records, Duncan was arrested on Dec. 18, 1993, and convicted in 1998. He spent approximately 28 years incarcerated for a crime he consistently maintained he did not commit.
The Louisiana Supreme Court opinion cited video evidence of West's 1993 examination of Haley that was not shown to jurors at trial. In the recording, West can be seen taking a mold of Duncan's teeth and grinding it into and across the girl's body, seemingly creating bite marks where none previously existed.
Nine other prisoners have been exonerated based on West and Hayne's work, with three of those individuals having been on death row. Duncan was described in court documents as "the last person awaiting an execution based on their work."
The National Registry of Exonerations has documented over 3,800 wrongful conviction cases in the United States since 1989, with false or misleading forensic evidence accounting for approximately 24 percent of those cases.
The Bottom Line
Duncan's release marks a significant moment in Louisiana's criminal justice history, ending what his attorneys called decades of wrongful incarceration based on debunked forensic science. The unanimous Supreme Court ruling effectively ends the state's ability to pursue capital charges against him.
The case now shifts to potential compensation claims. Louisiana law provides mechanisms for wrongfully convicted individuals to seek damages, though such cases can take years to resolve and face significant legal hurdles.
For advocates pushing for broader forensic science reform, Duncan's exoneration represents vindication of their long-standing concerns about junk science in criminal courts. The ruling may influence how lower courts evaluate similar bite mark evidence in pending cases statewide.
