Recently, in two separate cases in the Central Texas area, several wrongfully convicted people have been released from prison on the basis of evidence that their convictions were founded upon false scientific testimony. Both cases involved the sensitive matter of child sexual abuse. To read about the “San Antonio Four,” click here. To read about the Keller case in Austin, click here.
This past legislative session, Texas adopted a new law (codified as Article 11.073 in the Texas Code of Criminal Procedure) that makes it easier for falsely convicted people to overturn their convictions on the basis of false scientific evidence. Prior to the passage of the new law, defendants had the burden of proving that newly-discovered evidence establishes their actual innocence. But now, defendants only need to show by a preponderance of the evidence that if the new scientific evidence had been presented at their original trial, they would not have been convicted. Essentially, this means that if defendants show that it’s “more likely than not” that they wouldn’t have been convicted, the court must overturn the conviction.
As an example, consider the case of Cameron Todd Willingham, who was convicted of murdering his three young daughters by burning down the house while they slept. At trial, an arson investigator testified that the burn patterns demonstrated that the fire was intentionally started with an ignitable fluid, such as gasoline or paint thinner. This scientific testimony definitively countered the defense’s theory that Willingham was asleep when the fire began, perhaps caused by faulty electrical wiring in the house. Over a decade later, scientific advances in the field of arson investigation revealed that the expert’s “burn pattern analysis” was based on an unreliable scientific theory. Thus, Willingham was convicted on the basis of false science. Even so, he was executed before the Texas Innocence Project could convince a court to overturn his conviction. The new law would prevent such a wrongful execution.
