The Texas pardons board rejected a clemency appeal on Wednesday from an autistic man on death row whose murder conviction was based on what his lawyers say was a misdiagnosis of “shaken baby syndrome.”
Robert Roberson, 57, is scheduled to die by lethal injection at the state penitentiary in Huntsville on Thursday for the February 2002 death of his two-year-old daughter, Nikki.
The Texas Board of Pardons and Paroles took up Roberson’s case on Wednesday and declined by a 6-0 vote to recommend that Texas Governor Greg Abbott grant clemency.
Abbott is unable to grant clemency without a recommendation from the board, but he can grant a 30-day reprieve of Roberson’s death sentence.
Gretchen Sween, one of Roberson’s attorneys, urged the governor to grant the reprieve “so we can continue to pursue Mr Roberson’s innocence claim.”
“We pray that Governor Abbott does everything in his power to prevent the tragic, irreversible mistake of executing an innocent man,” Sween said.
Roberson’s case has drawn the attention of the Innocence Project, which works to reverse wrongful convictions, as well as best-selling American novelist John Grisham, Texas lawmakers and medical experts.
Also among those seeking to halt his execution is the man who put him behind bars — Brian Wharton, the former chief detective in the town of Palestine.
“Knowing everything that I know now, I am firmly convinced that Robert is an innocent man,” Wharton said at a recent press conference organized by Roberson’s supporters. “The system failed Robert.”
Grisham, author of the legal thrillers “The Firm” and “A Time to Kill,” also appeared at the event and said: “What’s amazing about Robert’s case is that there was no crime.”
Roberson’s lawyers say the diagnosis of shaken baby syndrome, made at the hospital where his chronically ill daughter died, was erroneous and the cause of death was in fact pneumonia, which was aggravated when doctors prescribed improper medication.
Sween, Roberson’s attorney, said there is “overwhelming new medical and scientific evidence” that shows that the little girl died of “natural and accidental causes, not abuse.”
According to his lawyers, Roberson would be the first person executed in the United States based on a conviction of shaken baby syndrome.
‘Unscientific’
According to Kate Judson of the Center for Integrity in Forensic Sciences, more than 30 parents and caregivers in 18 US states have been exonerated after being wrongfully convicted using “unscientific” shaken baby testimony.
Sween said Roberson’s autism spectrum disorder, which was not diagnosed until 2018, contributed to his arrest and conviction.
“It is quite possible that Mr Roberson would not be on death row today, but for his autism,” she said.
Sween said staff at the hospital where his daughter was admitted did not know he had autism and “judged his flat affect as a sign of guilt.”
A bipartisan group of 86 Texas state lawmakers has also urged clemency for Roberson, citing the “voluminous new scientific evidence” that casts doubt on his guilt.
There have been 19 executions in the United States this year.
