In a heartbreaking twist of fate, Robert Roberson is poised to become the first individual in the United States to face execution based on the controversial and largely discredited “shaken baby syndrome” theory. With his execution date set for October 17, advocates are urging Texas officials to take action before it’s too late.
Recently, Roberson’s legal team filed an emergency motion with the Texas Court of Criminal Appeals, pleading for a stay of execution. His attorney, Gretchen Sween, shared with ABC News the emotional turmoil Roberson is enduring. “He fluctuates between despair and a flicker of hope when he receives support,” Sween explained.
“Witnessing his struggle adds another layer of cruelty to this already painful process.”
The tragic case dates back to 2002 when Roberson discovered his 2-year-old daughter, Nikki, unresponsive on the floor beside his bed. After attempting to comfort her and returning to sleep, he awoke to find her lips blue and rushed her to the hospital, where she was sadly pronounced dead. Roberson was subsequently convicted based on a pediatrician’s testimony that attributed Nikki’s condition to shaken baby syndrome, a diagnosis that has faced increasing skepticism from the medical community.
Experts have raised questions about the validity of this diagnosis, citing a lack of robust evidence to support it. In fact, as new research has emerged, the theory has been scrutinized in both medical and legal circles. The medical examiner’s report suggested Nikki had suffered multiple head injuries and classified her death as a homicide.
Roberson’s legal team has highlighted that he is autistic, which affects his emotional expression—a factor that was also a concern during his trial. Since his conviction, significant new evidence has surfaced, indicating that Nikki was suffering from pneumonia and had been prescribed respiratory-suppressing medications shortly before her death. Experts assert that these drugs, including codeine and promethazine, could have severely impaired her breathing.
A toxicology report revealed concerning levels of promethazine in Nikki’s system, and lung pathology expert Dr. Francis Green found that she was battling both chronic and acute pneumonia, leading to sepsis and eventual organ failure.
In a powerful show of support, over 30 medical professionals have urged the Texas Board of Pardons and Paroles to reconsider Roberson’s conviction, emphasizing that no reputable doctor today would overlook alternative explanations for such medical conditions. “Accidental falls and natural diseases can produce similar symptoms to those attributed to inflicted injuries,” their letter stated.
Legal arguments continue to unfold, with Roberson’s team citing Texas law Article 11. 073, which allows for the review of wrongful convictions based on advancements in scientific understanding. A bipartisan coalition of 86 Texas House members has rallied behind Roberson’s plea for clemency, asserting that he deserves a new trial.
State Representative Lacey Hull expressed her deep concern after meeting Roberson, noting his enduring hope despite the dire circumstances.
In 2013, the Texas Court of Criminal Appeals denied Roberson’s request for a retrial, citing insufficient evidence. Most recently, the court dismissed his latest petition, labeling it an “𝓪𝓫𝓾𝓼𝓮 of the writ” without addressing the merits of his claims.
Adding to the complexity of the case, former lead detective Brian Wharton, who initially arrested Roberson based on the shaken baby theory, has since expressed remorse. In a heartfelt letter, he called for Roberson’s release, stating, “I will forever be haunted by the role I played in helping the State put this innocent man on death row.”
The shaken baby syndrome hypothesis has seen over 30 individuals exonerated since 1992, according to the National Registry of Exonerations. As the clock ticks down to Roberson’s execution date, the question remains: will Texas officials intervene to prevent a potential miscarriage of justice?
