A Louisiana man who spent 27 years on death row was released on bail after his murder conviction was overturned earlier this year in the 1993 death of his girlfriend’s toddler, his lawyers said.

The release Wednesday of Jimmie Duncan, 57, marked a “significant step forward in his long fight for justice,” one of his attorneys, Chris Fabricant, said in a statement.

Fabricant noted the role of what he called “fraudulent forensics” in Duncan’s conviction and described his incarceration as “a gross miscarriage of justice.”

“His execution would have been a moral outrage,” Fabricant added.

Duncan, who was convicted of first-degree murder in 1998 and had been incarcerated at Angola state prison, was released on $150,000 bond, The Associated Press reported.

The Innocence Project, whose attorneys have represented Duncan, said in a news release that 4th Judicial District Judge Alvin Sharp’s ruling finding Duncan “factually innocent” of the murder was appealed to the state’s high court and is set for oral arguments early next year.

The district attorney’s office that prosecuted Duncan could not be reached for comment Friday. In a statement cited by NBC affiliate KTVE of West Monroe, Louisiana, 4th District Attorney Steve Tew said his office is preparing to challenge the ruling.

Twenty three-month-old Haley Oliveaux died on Dec. 18, 1993, after Duncan briefly stepped away from the bathtub, according to the Innocence Project. When Duncan found her unconscious, he tried to perform CPR and sought help from neighbors who called 911.

She died shortly afterward at a hospital.

Duncan was convicted of the killing in part through forensic evidence. Experts for the prosecution linked what they described as bite marks found on the girl’s body to Duncan’s teeth, according to the Innocence Project.

In an April ruling, Sharp cited an expert for Duncan who rejected that conclusion and described bite mark analysis as “junk science” that is “not scientifically defensible.” Two experts who testified for Duncan said the toddler appeared to have died by accidental drowning and not homicide, according to the ruling.

The ruling from Sharp also found that Duncan’s trial attorney provided ineffective assistance of counsel.

According to the Innocence Project, at least 39 wrongful convictions and indictments across the United States have been attributed to the forensic techniques used in Duncan’s case. The group said that of the nearly 3,800 cases that have been documented by the National Registry of Exonerations since 1989, false or misleading forensic evidence has played a role in a quarter of them.
