Justice for Jeff

Jeff was taken in for questioning later that day and fully cooperated with investigators. He voluntarily surrendered his clothing, provided a DNA sample, consented to testing of his skin, and allowed detectives to photograph his entire body. 

Although Jeff was questioned on April 24, 1999, investigators did not have enough evidence to hold him or charge him with the murders. There were no eyewitnesses, no murder weapon, and no confession. Testing found no gunshot residue, accelerants, or other physical evidence linking him to the shootings or the fire. A search of Jeff’s home also failed to uncover evidence connecting him to the crime. 

Because the evidence did not support criminal charges at the time, Jeff was released, and the case eventually went cold.

The State suppressed favorable evidence regarding its use of informants and the DNA testimony in violation of the Due Process Clause. 

The writ argues that prosecutors withheld evidence that could have helped Jeff’s defense, including information about the jailhouse informants and evidence that undermined the State’s DNA theory. It further argues that this suppressed evidence would have given the defense powerful grounds to challenge both the credibility of the informants and the prosecution’s interpretation of the DNA evidence presented to the jury.

After Prible’s right to counsel had attached, the State used a covert agent to obtain information from him in violation of his Sixth Amendment rights pursuant to

Massiah v. United States.

The writ argues that, after Jeff had already been formally charged and had the right to have his attorney involved, the State used a jailhouse informant to secretly question him. It contends that Beckcom was effectively working for the prosecution and should not have been used to deliberately elicit information from Jeff outside the presence of counsel. The writ separately argues that the confession Beckcom later claimed Jeff made never actually occurred, as discussed in Claim 3.

The State sponsored false or misleading testimony through informant Beckcom in violation of Prible’s due process rights.

The writ argues that the prosecution presented testimony it knew—or should have known—was false or misleading and failed to correct it. It contends that this allowed the jury to hear a distorted version of key evidence, particularly concerning the State’s witnesses and the circumstances surrounding the case, in violation of Jeff’s right to a fair trial. 

Prible is entitled to habeas relief under Article 11.073. 

The writ argues that advances in DNA science have fundamentally undermined the DNA testimony used against Jeff at trial. Multiple experts now agree that the State’s interpretation of the evidence was scientifically unsound. Most significantly, the State’s own trial DNA expert, Dr. William Watson, has signed a sworn declaration acknowledging that he would testify differently today and cannot determine when the biological material found in Nilda Tirado’s mouth was deposited in relation to her death. Watson goes even further: he states that prosecutors misrepresented his testimony to the jury, attributing conclusions to him that he never gave and, in some instances, that he now says were not scientifically valid.

Prible is actually innocent.

The writ argues that the new evidence does not merely weaken individual parts of the prosecution’s case—it dismantles the case as a whole. The State’s DNA theory is no longer supported by contemporary science, and its own trial expert now acknowledges serious problems with the conclusions attributed to his testimony. The alleged jailhouse “confession” has likewise been undermined by evidence of false testimony, undisclosed dealings with informants, and the State’s use of an informant to deliberately question Jeff after he had been charged. The writ argues that these were the two pillars of the State’s case, and both have now collapsed.

Claim 5 also relies on new evidence pointing away from Jeff. A threatening letter sent to Steve Herrera’s parents—evidence the State possessed since 1999—was finally subjected to DNA testing in 2025, and Jeff was definitively excluded as a contributor. The writ also presents new testimony supporting Jeff’s account of his relationship with Nilda Tirado and evidence suggesting that another person or persons had the motive, knowledge, and willingness to commit the murders. Taken together, Jeff’s attorneys argue that the full record now establishes his actual innocence and that no reasonable jury hearing this evidence would convict him.
