As Siegler’s TV star has been rising over the last decade, a parallel reality has been playing out in Texas courts, where allegations of prosecutorial misconduct have tarnished Siegler’s reputation. Appellate litigation in murder cases handled by Siegler has exposed a history of withholding exculpatory evidence from defense attorneys, including in death penalty cases. One prominent criminal defense attorney has called on the Harris County District Attorney’s Office to review all of Siegler’s convictions.

Some of the most disturbing evidence of Siegler’s conduct is documented in the files of a case that has largely gone unnoticed: the 2002 conviction of Ronald Jeffrey Prible. Prible was sent to death row for the murder of a Houston family. The evidence tying him to the crime was entirely circumstantial. He has maintained his innocence for more than 20 years.

In 2020, a federal district judge overturned Prible’s conviction on the basis of Siegler’s suppression of evidence, ordering the state to retry or release him within six months. Instead, Texas fought the order, persuading the 5th U.S. Circuit Court of Appeals to reinstate Prible’s death sentence on procedural grounds. The court did not address Siegler’s actions. Prible appealed to the U.S. Supreme Court, but in June, the justices declined to intervene.

Today, Prible faces execution despite the fact that the case against him has unraveled. A monthslong investigation by The Intercept — including a review of thousands of pages of court records — shows that Prible’s case contains numerous hallmarks of wrongful convictions, from a shockingly inept police investigation to unsupportable junk science peddled by prosecutors at trial.
