CROSSOVER: The ‘Lover’s’ Testimony and the ‘Mother’s’ Bias: Leveraging Criminal Liability and Witness Credibility Standards in Family Litigation

Valdez v. State, 14-23-00070-CR, February 26, 2026.

On appeal from the 174th District Court of Harris County, Texas.

Synopsis

The Fourteenth Court of Appeals held that a trial court does not err by instructing a jury on principal, party, and conspirator liability when the evidence is sufficient to support multiple theories, even if the State’s primary theory identifies the defendant as the principal actor. The court clarified that as long as a rational jury could harbor doubt regarding which specific participant committed the act while still finding the defendant assisted in the offense, all applicable theories of liability must be submitted in the charge.

Relevance to Family Law

While Valdez originates in the criminal sphere, its application to high-stakes family law litigation—particularly regarding the “reconstitution” of the community estate and civil conspiracy—is profound. In complex property disputes where a spouse and a third party (such as a paramour or a business associate) are alleged to have conspired to waste or hide community assets, the “some evidence” threshold for jury instructions remains the standard. Valdez reinforces that a practitioner is entitled to instructions on both direct and vicarious liability if the evidence allows for any rational doubt as to who performed the specific act of dissipation. Furthermore, the court’s analysis of witness bias provides a potent weapon for impeaching the “insider” testimony of relatives and lovers frequently encountered in custody and divorce proceedings.

Case Summary

Fact Summary

The defendant, Reymundo Valdez, and his accomplice, Joel Sosa, went to a residence with the intent to rob the occupants, Ernesto Hull and Colette Depaz, using a fake brick of cocaine as a ruse. During the encounter, both victims were fatally shot. The State’s primary theory was that Valdez was the shooter. The evidentiary record included DNA evidence with “limited support” for Valdez’s presence, a fingerprint on a bullet cartridge, and testimony from Sosa’s mother—who was also Valdez’s lover at the time.

The mother testified that Valdez confessed to being the shooter. However, the defense argued that the cell phone records and the disposal of the murder weapon suggested Sosa was the actual killer. Following the murders, Valdez, Sosa, and the mother fled to Louisiana, deposited blood-stained cash into the mother’s account, and purchased a new vehicle. Despite the State’s focus on Valdez as the principal, the trial court submitted jury instructions on principal liability, party liability, and conspirator liability. Valdez appealed, arguing there was no evidence he acted as anything other than a principal.

Issues Decided

1. Whether a trial court errs by submitting instructions on party and conspirator liability when the State’s primary theory of the case is that the defendant acted as the principal actor.
2. Whether the evidence of an accomplice’s presence and participation at the scene is sufficient to warrant “party” instructions even if a witness claims the defendant confessed to the primary act.

Rules Applied

• Texas Code of Criminal Procedure Art. 36.14: Requires the trial court to deliver a written charge setting forth the law applicable to the case.
• In re State ex rel. Weeks, 391 S.W.3d 117 (Tex. Crim. App. 2013): Establishes that if multiple theories of liability are supported by “some evidence,” the State is entitled to their submission.
• Ransom v. State, 920 S.W.2d 288 (Tex. Crim. App. 1994): Confirms that when evidence is sufficient to support both primary and party theories, the court does not err in submitting both, particularly when a jury could disbelieve testimony regarding the identity of the primary actor.
• Evans v. State, 202 S.W.3d 158 (Tex. Crim. App. 2006): Recognizes that a jury may disbelieve the testimony of a witness with an obvious motive to protect a relative (e.g., a mother testifying for a son).

Application

The court’s application of the law turned on the jury’s role as the sole judge of witness credibility. The Fourteenth Court noted that while Sosa’s mother testified that Valdez confessed to the shooting, the jury was free to disbelieve her because she had an “obvious motive” to shield her son, Sosa, from criminal responsibility. By disregarding the mother’s specific claim that Valdez was the shooter, a rational jury could still find that Valdez was present and aided in the robbery-murder based on the DNA, fingerprints, and his flight from the jurisdiction.

The court reasoned that because the evidence showed both men were at the scene and both participated in the subsequent disposal of evidence and flight, there was “some evidence” that Valdez acted as a party or co-conspirator. The legal story here is one of evidentiary flexibility: the State is not “wed” to its primary theory in the jury charge if the facts on the ground allow for a different rational interpretation of the roles played by the participants.

Holding

The trial court’s judgment was affirmed. The court held that the trial court did not err in authorizing the jury to convict Valdez as a party or conspirator because the evidence was sufficient to support those theories, regardless of the State’s primary focus on principal liability.

The court further held that the existence of a familial or romantic relationship between a witness and a participant creates a credibility issue that justifies the submission of alternative liability theories, as the jury is entitled to believe portions of a witness’s testimony while rejecting others.

Practical Application

For the Texas family law litigator, this case serves as a strategic guide for the “Charge Conference.” When pleading claims for breach of fiduciary duty or fraud on the community involving a third-party co-conspirator, you must ensure your proposed charge is not overly narrow. If you can show “some evidence” of a joint enterprise—such as a spouse transferring funds to a paramour who then purchases an asset—you are entitled to conspirator and “party” (aiding and abetting) instructions.

Do not let an opponent argue that because your primary trial theme was “the husband stole the money,” you are barred from a conspiracy instruction. If the jury believes the husband was involved but doubts he was the sole actor, the absence of a conspiracy or aiding-and-abetting instruction could result in a take-nothing verdict.

Checklists

Securing Multiple Liability Theories in the Charge

• Audit the record for “some evidence” of a third party’s involvement, even if that party is not a named defendant.
• Identify acts of “assistance” or “encouragement” that differ from the primary act of liability.
• Draft broad-form questions that include “acting in concert” or “conspiracy” language.
• Object to any charge that limits the jury to a single theory of liability when the evidence suggests multiple actors were involved.

Impeaching the “Insider” Witness

• Document the specific relationship (familial, romantic, or financial) between the witness and the party.
• Highlight post-conduct actions (e.g., joint travel, shared bank accounts, or disposal of evidence) that suggest a unified interest.
• Request a jury instruction on witness credibility that emphasizes the jury’s right to believe all, some, or none of a witness’s testimony.
• Use the Evans standard in closing arguments to explain why a mother’s (or lover’s) testimony regarding a “confession” or “sole responsibility” should be viewed with extreme skepticism.

Family Law Crossover

Valdez is a masterclass in how to weaponize the “conspirator” theory in a divorce where the “Mother-in-Law” or “Paramour” is a key witness. In many cases, a mother-in-law will testify to protect her child’s interest in a separate property claim or to explain away a suspicious transfer of funds. Under the Valdez analysis, her bias is not just a point for cross-examination—it is the legal foundation that allows you to request a jury charge on conspiracy. By arguing that the jury can disbelieve her “principal” story (e.g., “I gave my son that money as a gift”), you open the door for the jury to find a conspiratorial “party” liability (e.g., “The spouse and the mother conspired to hide community funds”). This ruling prevents a witness’s self-serving testimony from narrowing the legal theories available to your client at the end of the trial.
