Texas Appeals Court Overturns 'Shaken Baby' Conviction Ahead of Execution Date in Another Disputed Case
The court found scientific opinion about "shaken baby syndrome" has changed, and a man sentenced to 35 years in prison deserves a new trial.

As the state of Texas prepares for the first execution in the country based on evidence of what used to be called "shaken baby syndrome," a state appeals court has overturned a conviction in a separate, similar case.
The Texas Criminal Court of Appeals ruled on Wednesday that Andrew Roark, a Dallas man who was sentenced to 35 years in prison in 2000 in a shaken baby case, deserves a new trial because it's unlikely that a jury would convict him today if they heard current scientific testimony. Two of the state's expert witnesses at Roark's trial later recanted portions of their testimony about the unlikelihood of accidental or natural causes for the symptoms they observed.
"We find that scientific knowledge has evolved regarding SBS and its application in [Roark's] case," the court wrote. "Additionally, we find that given further study, the experts would have given a different opinion on several issues at a trial today—some already have. The admissible scientific testimony at trial today would likely yield an acquittal."
There is likely no one else in the country as interested in the case, besides Roark, than Robert Roberson, a Texas death row inmate scheduled to be executed on October 17. Roberson would be the first person in the U.S. to be executed based on evidence of what used to be called "shaken baby syndrome," now officially called abusive head trauma (AHT).
Roberson's lawyers filed another appeal this week asking the Texas Criminal Court of Appeals to reconsider its previous decisions denying him relief in light of Roark's case, especially since both trials featured testimony from the same expert witness, Janet Squires—a licensed expert in child abuse pediatrics who has testified in hundreds of child-abuse trials.
"The same prosecution expert testified in both trials making many identical pronouncements about how shaking had to be the principal explanation for the child's brain condition, when science has since demonstrated that many things, including natural disease progression and accidental short falls with head impact, can cause the same conditions," Gretchen Sween, Roberson's attorney, said in a press release. "The flaws in the expert testimony are nearly identical."
As Reason detailed in a feature on Roberson's case in August, he was convicted in 2003 of murdering his two-year-old daughter Nikki and sentenced to death. He claimed that his daughter fell out of bed in the middle of the night, but he calmed her down and eventually got her back to sleep. He says he later woke up and discovered that she had stopped breathing and turned blue. Roberson took his daughter to the hospital, where she was declared brain dead and eventually taken off life support. Medical examiners found a trio of internal head conditions that were, at the time, considered to be conclusive evidence of violent shaking and impacts.
Roberson's lawyers argue that AHT amounts to junk science and that the scientific consensus around it has shifted dramatically since Roberson's conviction. His lawyers also argued in a petition for a stay of execution, filed this summer, that they had uncovered previously undisclosed medical records that proved Roberson's daughter died of severe viral and bacterial pneumonia, not trauma from shaking or abuse.
Among those who now believe that Roberson is innocent are the former detective who arrested him as well as novelist John Grisham, who wrote a feature on Roberson's case for D Magazine last month.
However, the Texas Court of Criminal Appeals rejected his last appeal. It found that Roberson's claims did not meet the standards for filing a subsequent petition for writ of habeas corpus—Roberson was previously granted a stay of execution and additional evidentiary hearings in 2016 but denied relief—and the court dismissed Roberson's new petition without reviewing it on the merits.
The State of Texas argues in a brief opposing Roberson's new motion to reconsider that Roark's case is "easily distinguishable," despite featuring testimony from the same expert witness. Roberson's conviction, the state argues, rested on findings of shaking and multiple blunt force impacts, in addition to witness testimony that he was short-tempered and violent.
"The experts—supported by the autopsy report—established that Nikki died because of the blunt force injuries [Roberson] inflicted upon her, combined with shaking," the state's brief says. "None of these experts' opinions have been recanted, in part or in whole."
However, the court opinion overturning Roark's conviction notes that the "state theorized that Applicant caused the infant victim serious bodily injury by violently shaking her and possibly striking her with or against something, respectively referred to as Shaken Baby Syndrome and Shaken Impact Syndrome."
Squires testified in Roark's case that it was possible the victim "had a shake and an impact."
Roberson's execution would come amid intense courtroom debate over the reliability of AHT evidence. Prosecutors and pediatric abuse specialists say there's broad scientific consensus around AHT, but innocence groups and advocates for forensic reform have successfully persuaded several state courts otherwise.
According to the National Registry of Exonerations, at least 34 parents and caregivers in 18 states convicted based on AHT evidence have been exonerated.

Shaken Clump of Cells Syndrome not a thing?
Shaken baby syndrome is junk science because the tail can’t possibly generate enough force to wag the bathwater.
You can order your sacrifice to old ones shaken or stirred, frozen or on the rocks.
“because it’s unlikely that a jury would convict him today if they heard CURRENT scientific testimony”
I can’t wait to see DNA become outdated science.
(because, remember, DNA can’t even tell male from female)
Oh, FFS:
So the idea that she suffered abusive head trauma is junk science but the fact that she suffered brain damage as the result of a concussion on a coffee table and then *again* when she either fell in the tub *or* fell out of her bed is *the* *definitive* explanation (and we all just ignore the genital bruising, the inconsistent testimonies, etc.)?
“The science of pushing someone down the stairs is junk science!” – Reason
My younger son has actually had several concussion because he is injury prone and ran into a soccer goal post once, fell off a skateboard once, and off a bike another time. Would an MRI be able to tell the difference between this and child abuse?
No, but if Mad has his data correct, this is once again Reason ignoring inconvenient data to push a narrative, something they do all to often when it comes to justice reform.
An actual impact to the head is entirely different from shaking with no actual impact in terms of concussion injury potential. The two aren’t comparable.
Right. There was impact to the head. It caused the rebleed. Nobody knows where it came from and there were other signs of abuse affirmed by EMTs, nurses, and other doctors.
The “SBS is junk science.” narrative is a logic fallacy. It’s like saying thrusting a knife up under someone’s sternum and turning it isn’t an exact science, it only ruptures the ventricle and kills people 75% of the time, so all these murderers are innocent.
Police aren’t out peeping in windows to find baby shakers. They are pressing teachers at school to coax/en trap hapless kids into saying their unsuspecting parents shake them. The kid shows up in the ER and the people there responsible for trying to potentially save their life try and figure out what happened.
Maybe, like with abortion and the Dobbs decision or gays being denied access in violation of medical POA, there are rogue doctors out there looking to hang shaken baby on any hapless mother and father but, would you bet on Reason to give you the impartial truth one way or the other?
It’s not even the data. It’s the utter retardation and pervasiveness of “social justice” and bleeding heart liberalism/libertinism. It’s old-school pre-Dark Ages “Holy Grail”-style *hypocritical*, just a fundamental disregard for logic and justice in pursuit of a dopamine hit in support of their own self-righteousness.
The thinking is, rather literally, along the lines of “If you can’t identify the murder weapon, then there was no murder.” The same dishonest notion that “Excited delirium was invented to excuse cops killing black people.” when their own citations show the term was invented by a coroner doing research with a half dozen bodies that weren’t involved in any police cases that had suffered spontaneous cardiac arrest but didn’t have lethal doses of cocaine/drugs in their system.
Somebody was in charge of the kid. On their watch the kid suffered brain damage. The idea that nobody should even think of investigating or prosecuting based on the fact that the kid suffered brain damage is itself brain-damage-inducing. Let alone the idea that it fundamentally overturns all the science and every case involved.
If you left your kid in the car, we can’t know if you did it on purpose or not. There is no scientific device that’s going to tell us one way or the other. Make sure not to leave your kid in the car.
Similarly, if your kid suffers a concussion and you chase them out of the tub and they slip and fall, and then you chase them to bed and they fall again… rebleeds two weeks later don’t just happen. You may not have intended to kill them any more than the guy who accidentally locked their kid in the car. No medical test is going to tell us whether you pushed them or not and the fact that you’re using that as an excuse is it’s own dishonesty (to say nothing of the fact that more than half the fuckers walking around free were wearing masks and forcing everyone six feet apart on the premise of saving Grandma).
All kinds of mammals can and do flail, crush, and kill shake animals to death. Animals that, because of dramatically lower or higher mass, poorer leaver arms, and differing biomolecular makeup are far less capable of force generation than humans. Dogs, Wolves, all manner of primates, alligators and crocodiles, Orcas… Frequently, but not always, it’s the result of a fractured skull or vertebra. The idea that just because an average human can’t sever a particular neuron in a specific way through rate of force production means that no human anywhere could’ve ever killed another by shaking, flailing, crushing, or a combination of the three is patently absurd. The idea of flippantly going around overturning cases on the declaration of “Junk science!” is proving to be every bit as dishonest as going around shouting “Witch!” and lighting people on fire.
Would an MRI be able to tell the difference between this and child abuse?
1, 3, 6 mos. apart? Absolutely. Two weeks, maybe, maybe not. That said, as indicated in the story, after the first ~72 hours, rebleeds don’t just happen. There has to be more trauma from somewhere.
This, however, is still dishonest and/or hypocritical. If I shove your kid into the wall and give them brain damage, the MRI isn’t going to show whether he slipped or I pushed him. If there’s bruising on his genitals as noted by every medical professional who saw him, but they didn’t run his groin through the MRI, it obviously won’t show whether anyone abused him or not. It may seem stupid that I have to say this latter point but that’s the level of hypocritical stupidity you’re operating at.
Moreover you would, however, be perfectly correct in calling for a more thorough investigation into what happened. Even perfectly correct in going so far as pressing criminal charges, hiring your own TBI specialist to testify, etc. That’s how the law is supposed to work.
Not by going around shouting “Junk Science! Innocent!”.
It may seem stupid that I have to say this latter point but that’s the level of hypocritical stupidity
you’rewe’re operating at.The royal “you’re”.
As indicated in the article. The ‘good’ case leans pretty hard in the “SBS/TBI wasn’t the only reason abuse was suspected.” direction. The fact that they’re trying to extrapolate it to another case where the testimony is effectively, ‘Yeah, this kid suffered multiple concussions back to back to back within the span of a couple hours and died. Either someone beat him to death or he fell into an empty, running cement mixer.’ just demonstrates they aren’t operating in support of objectivity, honesty, or any strict adherence to impartial individual judgement or strict/maximal moral good.

“Shaking babies – 100% safe and effective, with no downsides.” – Reason
It bothers me that Reason refuses to accept the results of a court case. It’s not helpful when people on one side won’t accept the outcome.
Not just won’t accept the results of a court case, the results of one court case should be extrapolated to all the others.
It’s (mob action generally, of course, but specifically) activist legislation.
In what way is Reason refusing to accept the results of a court case?
“Andrew Roark, a Dallas man who was sentenced to 35 years in prison in 2000 in a shaken baby case, deserves a new trial…”
That court case. Reason refusing to say they accept that outcome “isn’t helping.”
Not just that.
I have been told in no uncertain terms that only insurrectionist conspiracy theorists question a scientific “consensus.”
All the people who unwound the shaken baby syndrome consensus should be stocked and pilloried.
