CROSSOVER: El Paso Court Upholds Exclusion of Defense Expert and Rejects Speedy‑Trial Attack in Bar Shooting—Playbook for Family‑Violence Crossover Cases

Moises Galvan v. The State of Texas, 08-23-00346-CR, March 31, 2026.

On appeal from 168th District Court, El Paso County, Texas

Synopsis

The El Paso Court of Appeals affirmed murder and aggravated-assault convictions, rejecting alleged jury-charge error, upholding the trial court’s exclusion of a defense expert opinion, and finding no cumulative error. The court also rejected a Sixth Amendment speedy-trial challenge arising from the lengthy delay between indictment and a retrial following mistrial, declining to dismiss the indictments with prejudice.

Relevance to Family Law

For Texas family-law litigators handling protective orders, SAPCRs, and divorce cases with parallel criminal exposure (family violence, weapons, assaultive conduct), Galvan is a practical reminder that (1) expert opinions must be tightly moored to admissible foundations and preserved with a clean, specific offer of proof, and (2) “delay” arguments—often repurposed as due-process/fundamental-fairness themes in family cases—require disciplined proof of prejudice and a record showing the litigant asserted the right and was harmed by the delay. When a custody case hinges on a pending or recently tried violent-offense prosecution, Galvan also gives a roadmap for attacking (or defending) “self-defense narrative” expert testimony and for leveraging credibility fractures created by shifting prior statements against video/forensic evidence.

Case Summary

Fact Summary

The prosecution arose from a January 29, 2017 shooting outside an El Paso bar (Bar Fly) that injured David Ortega and killed Rogelio Franco, Jr. Galvan admitted he shot both men but claimed self-defense, grounding his fear in prior violent encounters with Franco and asserting Ortega approached with a dark object that he believed to be a gun, which Galvan wrestled away before it discharged.

The State’s case emphasized: eyewitness testimony (including Ortega), a deputy constable’s pursuit and recovery of the Ruger pistol, gunshot residue on Galvan’s hand, DNA on the pistol consistent with Galvan while excluding Ortega and Franco, spent casings at the scene, and medical examiner testimony placing shots generally front-to-back with stippling suggesting close-range firing (within inches to feet). The State also highlighted Galvan’s post-arrest statement that initially denied involvement and conflicted with security video showing Galvan’s movements and entry/exit sequence.

Procedurally, Galvan’s first jury trial in May 2019 ended in a mistrial. His retrial occurred in September 2023, resulting in convictions and significant concurrent sentences. On appeal, he challenged the jury charge, the exclusion of a defense expert opinion, cumulative error, and asserted a Sixth Amendment speedy-trial violation based on the time between indictment and retrial after mistrial.

Issues Decided

• Whether alleged jury-charge error required reversal.
• Whether exclusion of the defense expert’s proffered opinion was an abuse of discretion and, if error, whether it caused harm.
• Whether cumulative error warranted a new trial.
• Whether the delay between indictment and retrial after mistrial violated the Sixth Amendment right to a speedy trial and required dismissal with prejudice.

Rules Applied

• Jury-charge review (Texas criminal appellate framework): preservation-dependent standards; reversible error requires showing harm under the applicable harm standard (egregious harm if unpreserved; “some harm” if preserved).
• Evidentiary rulings / expert testimony: abuse-of-discretion review; proponent must demonstrate admissibility, reliability/fit, and preserve the substance of excluded testimony through a proper offer of proof/bill.
• Cumulative error doctrine: multiple non-reversible errors may, in rare circumstances, cumulatively deprive a defendant of a fair trial; absent actual errors (or absent harm), cumulative-error relief fails.
• Sixth Amendment speedy trial: Barker v. Wingo balancing (length of delay, reason for delay, assertion of the right, prejudice), applied to the procedural posture presented (including retrial after mistrial).

Application

On the charge complaints, the court treated the alleged problems as non-reversible in the posture presented, concluding Galvan did not carry his burden to show charge error warranting a new trial under the governing harm analysis. The opinion’s through-line is pragmatic: appellate courts will not reverse on abstract “could-have-mattered” theories when the record does not demonstrate the complained-of instruction actually skewed the jury’s decision under the applicable standard.

On the excluded expert, the court credited the trial judge’s gatekeeping discretion. The appellate court’s analysis effectively reinforces two recurring constraints: (1) expert testimony must “fit” the disputed factual issues in a way that assists the trier of fact rather than merely advocate a narrative, and (2) even if the defense can articulate a theory for admission, the proponent still must show the exclusion was outside the zone of reasonable disagreement and that the exclusion probably affected the verdict. Against the State’s video/forensic and credibility impeachment proof, the appellate court was not persuaded the missing expert opinion cleared the harm threshold.

On cumulative error, the court declined to aggregate complaints into a new-trial remedy where the underlying predicates did not amount to multiple harmful errors. In other words, cumulative error is not a back door to harm when each individual complaint fails on error or harm.

Finally, on speedy trial, the court applied the Barker framework and rejected dismissal. While the passage of time was substantial, the court’s disposition reflects the familiar appellate demand for a developed record on (a) why the delay occurred, (b) whether and when the defendant asserted the right, and (c) concrete prejudice—especially impairment to the defense—rather than generalized anxiety or incarceration. The court declined the requested with-prejudice dismissal.

Holding

The court held that Galvan failed to show reversible jury-charge error. The convictions were affirmed because any charge complaint did not satisfy the applicable harm standard in light of the record as a whole.

The court held the trial court did not abuse its discretion in excluding the proffered defense expert opinion, and in any event Galvan failed to demonstrate harm from the exclusion sufficient to warrant reversal.

The court held cumulative-error relief was not available because the asserted errors did not collectively deprive Galvan of a fair trial.

The court held no Sixth Amendment speedy-trial violation warranted dismissal, and the court declined to dismiss the indictments with prejudice after balancing the Barker v. Wingo factors on the record presented.

Practical Application

For family-law litigators, Galvan is less about criminal doctrine and more about how appellate courts evaluate record-building, expert exclusions, and delay narratives—exactly the pressure points that appear in family-violence crossover dockets.

• Expert “self-defense dynamics” and “perception” testimony: In SAPCRs and protective orders, parties increasingly try to introduce experts to recast violent conduct as “reasonable perception,” “reaction time,” “trauma response,” or “threat assessment.” Galvan underscores that if the opinion is not tightly connected to reliable inputs and a permissible ultimate issue, the trial court has broad discretion to exclude it—and appellate courts will often affirm absent a meticulous offer of proof and a persuasive harm story.
• Video + prior inconsistent statements: The State’s use of security video to impeach Galvan’s story is the template family lawyers see with Ring doorbells, bodycam, jail calls, and phone extractions. Once the factfinder has a “truth anchor” (video/forensics), appellate courts are skeptical that an excluded expert or instruction nuance would have changed the outcome.
• Delay arguments in family cases: In family court, litigants often argue “the other side delayed the case, so I’m prejudiced.” Galvan is a reminder that delay-only themes win when they are coupled to specific prejudice: lost witnesses, degraded evidence, changed circumstances that impair the ability to present a case, or demonstrable impact on a child’s welfare. Courts want proof, not rhetoric.
• Cumulative-error framing: Family appeals sometimes stack multiple discretionary rulings (continuances, evidentiary calls, discovery limitations) into “the trial wasn’t fair.” Galvan signals the risk: if each individual complaint fails on preservation, error, or harm, cumulative-error packaging usually fails too.

Checklists

Preserving Excluded Expert Testimony (Family-Violence Crossover)

• Obtain a clear ruling on admissibility (not a “we’ll see” deferral).
• Make a detailed offer of proof outside the presence of the factfinder.
• Tie the opinion to identified, admissible facts (and show the expert reviewed them).
• Establish the methodology and why it reliably applies to the case.
• Demonstrate “fit”: how the opinion assists the court on a disputed issue (not credibility bolstering).
• Preserve exhibits/data the expert relied upon (videos, photos, medical records, phone records).
• If exclusion is likely, request a running bill or ensure the offer is transcribed and specific.

Building a “Delay = Prejudice” Record in SAPCR/Divorce

• File written requests for settings and obtain written denials/continuances in the record.
• Identify the reason for each delay (opponent, court congestion, discovery disputes, criminal case pendency).
• Prove concrete prejudice:
• witness unavailability (with dates, subpoenas, and diligence),
• lost/destroyed digital evidence,
• faded memory tied to specific disputed events,
• child-related harm (missed treatment continuity, school instability, therapy gaps) tied to the delay.
• Re-urge requests for temporary orders that mitigate prejudice while waiting (possession, injunctions, supervised visitation).
• Make the “assertion of the right” unmistakable—on the record, repeatedly, with proposed dates.

Using Video/Forensics to Neutralize a Self-Defense Narrative

• Authenticate early (business records, device extraction, custodian affidavits where available).
• Create a timeline exhibit: entry/exit, lighting conditions, distances, sequence of movements.
• Pair video with impeachment anchors:
• prior statements,
• text messages,
• social posts,
• police reports/affidavits,
• medical records.
• If the other side offers an expert, force concessions on what the video does and does not show.
• In bench trials, request explicit findings tied to the video and objective evidence.

Avoiding “Cumulative Error” Traps on Appeal

• Preserve each complaint as if it will be the only issue on appeal.
• Request findings of fact/conclusions of law where available (family cases) to isolate harmful rulings.
• Make harm specific: identify the exact piece of evidence excluded/admitted and how it changed the outcome.
• Avoid overloading the brief with weak issues that dilute the strongest preserved error.

Family Law Crossover

Family litigants weaponize criminal-case rulings in two main ways: (1) to argue the other side is trying to “relitigate” the criminal case through experts and narratives the trial judge has discretion to exclude, and (2) to repackage criminal delay as civil “unfairness.” Galvan is useful authority-by-analogy for the proposition that trial courts have broad discretion to exclude an expert opinion that does not reliably fit the issues, and that appellate courts will demand a disciplined showing of prejudice before granting the most drastic remedies. In a custody or divorce case involving alleged family violence with parallel criminal proceedings, the prevailing party can cite Galvan’s posture to argue: “The court should focus on objective evidence (video, medical records, admissions), not speculative expert gloss; and absent a record of concrete prejudice, the opponent’s delay narrative should not drive extraordinary relief.” Conversely, if you need the expert, Galvan is your warning label: build the foundation, make the offer of proof airtight, and articulate harm in outcome terms—because on appeal, “the judge kept my expert out” is not self-executing reversible error.
