Shaken Child Syndrome Has Been Discredited. Why Is Robert Roberson Nonetheless on Loss of life Row?
Convicted of against the law that by no means occurred, Roberson’s case is a chief instance of how the U.S. authorized system typically fails to acknowledge advances in scientific data
In a last-minute effort to avoid wasting the lifetime of a man on loss of life row, a bipartisan group of Texas legislators has simply accomplished one thing extraordinary: they’ve unanimously subpoenaed Robert Roberson, convicted in 2003 of killing his daughter based mostly on the now-discredited idea of shaken child syndrome, to testify earlier than them 5 days after he was scheduled to be executed, successfully forcing the state to maintain him alive.
Roberson is one among many individuals who’ve been imprisoned for accidents to a toddler that prosecutors argue resulted from violent shaking. However analysis has uncovered severe flaws in these determinations, and dozens of different defendants who’ve been wrongly convicted below this idea have been exonerated. But Roberson stays on loss of life row, whilst politicians, scientists and others—together with the lead detective who investigated him and one of many jurors who convicted him—have spoken out on his behalf. If his execution proceeds, they and plenty of others consider that Texas will likely be killing an harmless man for a “crime” that by no means occurred.
As our scientific understanding of shaken child syndrome has developed over the previous 20 years, justice requires that courts reexamine previous convictions in gentle of latest findings. That is very true for Roberson, who can be the primary individual within the U.S. to be executed for a conviction based mostly on shaken child syndrome. Regardless of one’s view of the loss of life penalty, the last word punishment have to be held to the last word customary of proof—and Roberson’s case falls woefully in need of that customary.

The speculation behind shaken child syndrome dates again to the early Nineteen Seventies, when two medical researchers—Norman Guthkelch and John Caffey—individually revealed the primary scientific papers explaining that shaking an toddler may cause deadly inner accidents even absent exterior accidents. Over time physicians and regulation enforcement officers, amongst others, extensively started to depend on a triad of signs—mind bleeding, mind swelling and retinal bleeding—as definitive proof that somebody had abused a toddler by shaking. To help this idea, researchers cited circumstances wherein a toddler displayed these signs and a caretaker confessed to shaking the kid, which ostensibly confirmed the triad as a dependable strategy to diagnose abuse.
There isn’t a doubt that shaking a toddler may cause accidents, together with people who comprise the shaken child syndrome triad. Newer analysis, nevertheless, has proven that shaking isn’t the solely strategy to trigger these accidents: They’ll additionally consequence from an unintentional “quick fall” (e.g., falling off a mattress) in addition to from different medical causes (e.g., pneumonia, improper medicine)—all of which have been true of Roberson’s daughter. Actually, a 2024 examine discovered that the accidents traditionally used to diagnose shaking are literally extra more likely to consequence from accidents than from shaking. In brief, fashionable science understands that the presence of those signs doesn’t essentially imply {that a} youngster was abused, nor does their absence imply that they weren’t abused.
Why did clinicians wrongly belief this triad of signs for thus lengthy? The quick reply is that correcting misconceptions requires a suggestions loop that’s typically missing in youngster abuse investigations. When a health care provider diagnoses a residing grownup and prescribes a therapy, the effectiveness of that therapy supplies suggestions on the correctness of their prognosis; if the therapy proves ineffective, docs can be taught from this misdiagnosis and alter future diagnoses accordingly. Such suggestions, nevertheless, isn’t at all times ample; as an example, docs practiced bloodletting for hundreds of years as a result of it was typically accepted and appeared to work for some sufferers, although it was an illusory correlation. With respect to shaking, docs not often be taught whether or not a toddler was really shaken as a result of the kid is often deceased or unable to articulate what occurred, and thus docs not often obtain suggestions that the triad led to an incorrect prognosis.
As for the research that used a caretaker’s confession to ascertain that abuse occurred, it’s now well-known that harmless individuals typically confess to crimes they didn’t commit, such that confessions are not synonymous with reality. Some students have even argued that the distinctive circumstances of suspected shaking circumstances (e.g., suspects’ emotional state) create an particularly excessive threat of false confession.
Additional complicating issues, youngster abuse determinations are topic to cognitive bias, wherein extraneous info leads specialists to interpret the identical harm in numerous methods—not less than one among which have to be incorrect. In a single examine, for instance, medical professionals extra typically judged the identical childhood harm as abuse quite than an accident if informed that the kid’s dad and mom have been single or drug customers—each of which seem like true of Roberson. One other examine discovered that those self same extraneous elements led emergency room docs to misdiagnose unintentional accidents as abuse in a staggering 83 % of circumstances.
Even merely figuring out a couple of prison accusation can have an effect on how a health care provider appraises a toddler’s accidents. In a single examine, unbiased specialists reviewed medical data from circumstances the place, unbeknownst to them, a fellow professional had testified that the kid was shaken. In 94 % of these circumstances, the unbiased specialists concluded that the kid’s “head accidents… probably, and even in all probability, had a non-traumatic trigger.”
Post-mortem selections are likewise unreliable. In a 2021 examine, medical experts’ opinions of whether or not a toddler’s loss of life was an accident or murder have been closely swayed by the kid’s race and who introduced them to the hospital, though the kid’s accidents and historical past have been in any other case an identical. In response, outstanding medical experts defined that method of loss of life is “not a ‘scientific’ willpower” and “typically doesn’t match nicely in court docket.” But jurors—together with some from at Roberson’s trial—typically hear and belief these tenuous opinions, which has led some students to argue that method of loss of life testimony shouldn’t be admissible in U.S. courts, as is the case in almost each different nation.
As analysis debunking shaken child syndrome has grown, so too have profitable authorized challenges to prison convictions that hinge on it, together with one other Texas case the place—simply eight days earlier than Roberson’s scheduled execution—a person was granted a brand new trial on the grounds that “scientific data has developed” since his 2004 trial and “would possible yield an acquittal” in 2024. Earlier than his 2016 loss of life, even Guthkelch—one of many architects of the idea—lamented that his “pleasant suggestion for avoiding harm to youngsters has grow to be an excuse for imprisoning harmless dad and mom.” Roberson is a type of harmless dad and mom.
Science is consistently evolving, and when it reveals a previous mistake, we don’t merely resign ourselves to it; we take corrective motion. Our authorized system ought to be no totally different. When Robert Roberson was convicted, the harm triad was extensively accepted as proof of shaking—however as science has progressed, that’s not the case. The regulation’s assure of due course of should account for such progress, particularly when an individual’s life actually will depend on it. For the regulation to disregard evolving scientific data isn’t merely unfair; it’s prison.
