Automated Summary
Key Facts
The Colorado Court of Appeals reversed Daniel Michael Boerner's conviction for sexual assault on a child and incest due to prosecutorial misconduct. The prosecutor improperly asked Boerner to opine on the truthfulness of the victims' testimonies, which is a well-established violation of legal principles. The court found this error obvious and substantial, necessitating a new trial. While the evidence was deemed sufficient for the charges related to the daughter, the case was remanded for retrial on those counts. The misconduct involved repeated impermissible 'were they lying' questions during cross-examination, undermining the trial's fairness.
Issues
- The defendant raised a claim of cumulative error. The court did not address this issue as the reversal on prosecutorial misconduct made it unlikely to arise on remand.
- The defendant claimed the court admitted improper testimony related to the detective's 'screening' of cases, his arrest warrant, and references to department of human services cases. This issue was not addressed due to reversal on prosecutorial misconduct.
- The defendant argued the district court erred by allowing the jury unfettered access to the victims' forensic interviews during deliberations. This issue was not addressed as the case was reversed on prosecutorial misconduct grounds.
- The court found that the prosecutor engaged in misconduct by asking the defendant to opine on the veracity of other witnesses, which was deemed obvious and substantial error requiring reversal.
- The court determined that there was sufficient evidence to support the sexual assault and incest convictions related to the daughter, allowing for a retrial on those counts after reversing the judgment due to prosecutorial misconduct.
Holdings
- The court concluded that the district court erred by allowing the prosecutor to engage in misconduct through impermissible 'were they lying' type questions during the defendant's cross-examination. This error was deemed obvious and substantial, warranting reversal of the judgment and remand for a new trial.
- The court determined that there was sufficient evidence to support the sexual assault and incest convictions relating to the daughter, despite her contradictory trial testimony. The jury's credibility determination was deemed valid, allowing retrial on those counts.
Remedies
The court reversed the judgment of conviction and remanded the case to the district court for a new trial. This remedy was granted because the prosecutor engaged in obvious and substantial misconduct by asking the defendant to opine on the veracity of other witnesses' testimony, which undermined the fundamental fairness of the trial. The reversal applies to all charges, but the court also determined there was sufficient evidence for retrial on the daughter-related convictions.
Legal Principles
The court applied the well-settled legal principle that prosecutors may not ask a testifying defendant to opine on the truthfulness of other witnesses, as such questioning is categorically impermissible and infringes on the jury's role in assessing credibility. This rule was established in Liggett v. People, 135 P.3d 725 (Colo. 2006), and reaffirmed in People v. Lopez, 2024 COA 26, ¶ 27.

Passage Text
- The lack of physical evidence presented at trial meant this case turned on the credibility of those who testified. And it is well established that credibility determinations are a 'matter solely within the province of the jury.'
- We conclude that the court allowed the prosecutor to engage in misconduct and that the error was obvious and substantial, requiring reversal.
