STORY: "Will a Texas law that overturns convictions based on bad science save this death row inmate," by reporter Jolie McCullough, published by the Texas Tribune on August 16, 2018.
Roberson’s attorneys argue in part that new
scientific evidence has suggested it is impossible to shake a toddler to
death without causing serious neck injuries, which Nikki did not have,
and has linked the symptoms used to diagnose shaken baby syndrome to
other conditions as well, including short-distance falls. “There has been a tremendous amount of new
scientific evidence,” said Gary Udashen, board president of the
Innocence Project of Texas. “Biomechanical engineering studies have
shown that you can generate enough force from a short-distance fall to
cause serious head injuries.” Over time, science has become an increasingly present part
of criminal proceedings, but it’s always evolving — what may have been
thought of as irrefutable scientific evidence 15 years ago could be
balked at today. And scientific “experts” who testify in cases sometimes
lack any true expertise. The origins of the junk science law, and Roberson’s renewed
chance at an appeal, began to take form as the state’s skepticism of
forensic science grew with the science's prevalence — think DNA — and
after several high-profile cases involving “bad science” emerged. Perhaps the most well-known is the case of Cameron Todd Willingham,
a Corsicana man executed in 2004 for the deaths of his three young
daughters, despite scientists discrediting the earlier fire examination
and finding no reason to call the house fire that killed his children
arson. But while state lawmakers passed other bills related to
forensic science, like creating a statewide investigatory commission, it
took several tries for the junk science law to make it out of the
Capitol in Austin. Whitmire filed similar bills in 2009 and 2011, but
neither piqued much interest, and some prosecutors said an already
well-established appeals process made the bill unnecessary. That changed with Neal Robbins and Cathy Henderson.
Both were convicted in infant deaths after the medical examiners who
testified at their trials later recanted their certainty that the deaths
were homicides. But their appeals based on those recantations produced
opposite results. In 2011, the Texas Court of Criminal Appeals denied
Robbins’ appeal on the claim that his conviction and life sentence were
based on bad scientific testimony — the medical examiner had changed her
original conclusion that said his daughter’s death could only be
murder. Though she originally thought the child’s injuries couldn’t have
been caused by the reported attempts at CPR, she later said her
increased knowledge made her unable to determine a cause of death. The next year, the same court tossed out Henderson’s conviction and
death sentence after scientific advancements conflicted with the
medical examiner’s original testimony that dropping a baby from her arms
onto the floor couldn’t have caused the fatal brain injury. “In Robbins, this Court chose finality over accuracy; in
Henderson we did the opposite, and in 2013, the Texas Legislature also
chose accuracy over finality,” wrote then-Judge Cathy Cochran in 2014
after the court, under the new law, overturned Robbins' conviction. He
was released from prison in 2016. Robbins’ appellate attorney, Brian Wice, said the blowback
from the court’s first ruling created the support to eventually pass the
bill. “It was a watershed moment, not just in Texas but
nationally, because Texas was really the first state to enact a
provision that was able to unlock the courthouse door to defendants like
Neal Robbins,” he said. For Roberson, the junk science law has extended his life,
but it hasn’t saved him yet. His court-ordered examination finally began
in what was assumed to be at least a week-long hearing Tuesday. But it
was again delayed after several hours when it was announced that
long-lost evidence, including Nikki’s brain scans, was suddenly found in
the basement of the local district clerk’s office.
Sween, his attorney, said in court that they ultimately
want a new trial for Roberson, one that would include the changes in
science on shaken baby syndrome and short-distance falls, as well as a
deeper look into Nikki’s previous illnesses and history of breathing
problems. The child had previously suffered spells where she'd stop
breathing and turn blue, and she had been at the hospital only days
before with a violent illness that included a 104.5-degree temperature,
according to court documents. The review is also looking at whether the
original accusation that Roberson sexually assaulted Nikki, which was
dropped mid-trial when the evidence couldn't be corroborated, affected
his conviction. She said she’s optimistic Roberson can be given a fair shot. “All we have to do is show that the science that was
presented at trial and the science that was available now ... has
changed in ways that more likely than not, might have changed the jury’s
verdict,” she said in court. But the prosecution said it isn’t conceding anything,
saying in court that the evidence was “clear and convincing” that
Roberson killed his daughter. “The science has not changed as much as [Roberson’s
attorneys] say,” said Anderson County Assistant District Attorney Scott
Holden in his opening statement. “There was no explanation except for
the intentional death of Nikki Curtis.” For now, Roberson’s case is up in the air. With the
discovery of the lost evidence Tuesday, the judge put it up to the
county and Roberson’s attorneys to let her know after they’ve properly
evaluated it. After the court does reconvene again, the judge will make a
recommendation to the Court of Criminal Appeals on whether a new trial
should be granted, which the higher court can either order or reject. Likely, it will be a lengthy delay, and the wait isn't
welcome news for Nikki’s older half-brother, Matthew Bowman. He still
carries the weight of his sister’s death and has no doubt that Roberson
killed her. He was 4 when she died, and the 20-year-old sitting in the
courtroom Tuesday was in visible anguish listening to Sween proclaim Roberson’s innocence, often shaking his head with a clenched jaw. He
shook and wiped tears from his eyes when an emergency room nurse on the
witness stand described her lifeless body. “I do believe that all the science that’s coming up is
B.S., and we shouldn’t even be here right now,” he said during a break
outside the courtroom. “I think everything should have been done and
taken care of a long time ago.""
