Background
Santos Renteria-Delgado was convicted by a jury in Douglas County District Court of two counts of first degree sexual assault of a child — one count each involving victims J.S. and X.S. — and sentenced to an aggregate mandatory minimum of 30 years with a maximum of 50 years’ imprisonment. On direct appeal, he argued his trial counsel was ineffective for failing to call the victims’ grandparents as promised during opening statements and for failing to properly impeach the victims with prior inconsistent statements. The Court of Appeals found the record insufficient to resolve those claims but otherwise affirmed the convictions and sentences.
After the mandate issued, Renteria-Delgado filed a verified motion for postconviction relief in August 2023. He reasserted the two ineffective-assistance claims from his direct appeal and added a third — that trial counsel failed to disclose a conflict of interest with a trial witness. An evidentiary hearing was held in February 2025, at which the district court received trial counsel’s deposition testimony, depositions of both victims, and an affidavit from the victims’ grandmother.
The district court denied relief on all claims. It found the decision not to call the grandparents was reasonable trial strategy, that J.S.’s deposition and trial testimony were not materially inconsistent, that the record refuted prejudice as to X.S.’s impeachment, and that the conflict-of-interest claim was procedurally barred because it had not been raised on direct appeal. Renteria-Delgado appealed on the three claims preserved from his direct appeal, abandoning the conflict-of-interest issue.
The Court’s Holding
The Court of Appeals affirmed across the board. On the grandparents claim, the court found that trial counsel’s decision not to call the grandparents after promising them in opening statements was supported by a detailed and articulated strategic rationale: family tension, the grandmother’s volatile temperament, the grandfather’s unwillingness to participate, and the risk that her testimony would reinforce doubts about Renteria-Delgado’s credibility. Because those reasons fell within the wide range of professionally competent conduct under Strickland v. Washington, counsel was not deficient. The grandmother’s two-page affidavit, the only evidence of what she would have said, did not undermine confidence in the verdict, so prejudice was also absent.
On the impeachment claims as to both J.S. and X.S., the court rejected Renteria-Delgado’s arguments because he never identified — not in his postconviction motion, not at the evidentiary hearing, and not in his appellate brief — the specific deposition passages he contended contradicted the victims’ trial testimony. The court emphasized that in postconviction proceedings the defendant bears the burden to demonstrate constitutional ineffectiveness, and an appellate court will not scour the record to supply specifics the appellant failed to provide. The district court had independently reviewed J.S.’s entire deposition and found it consistent with her trial testimony; the court of appeals found no clear error in that factual determination.
Key Takeaways
- Failing to call witnesses promised in opening statements is not per se ineffective assistance; a well-articulated strategic rationale — documented in counsel’s deposition — can satisfy Strickland‘s performance prong.
- A postconviction claim of improper impeachment will fail if the defendant never identifies the specific deposition passages that allegedly contradict trial testimony; the burden to prove ineffective assistance rests squarely on the defendant.
- An ineffective-assistance claim not raised on direct appeal (here, the conflict-of-interest allegation) is procedurally barred and cannot be revived in postconviction proceedings.
- Appellate courts review a trial court’s factual findings from a postconviction evidentiary hearing only for clear error and will not substitute their own findings where the record supports the lower court’s conclusions.
Why It Matters
The decision reinforces the high bar defendants face when challenging trial counsel’s witness decisions through postconviction relief. Strategic choices — even those that diverge from promises made in opening statements — are evaluated with deference to counsel’s judgment at the time, provided counsel can articulate a legitimate reason. Defense attorneys should document their mid-trial strategic pivots carefully, as counsel’s deposition testimony here was the dispositive evidence against the ineffectiveness claim.
The ruling also serves as a practical reminder to postconviction practitioners: vague allegations of impeachment failure, unmoored from specific transcript citations, will not survive scrutiny. Courts expect pinpoint record references, and the absence of them is fatal — the appellate court expressly declined to search the deposition record on the defendant’s behalf.
