Background
Demetrius Anthony Lucero was charged with three counts of sexual assault, along with trespass, unlawful sexual contact, and false imprisonment, after M.T. reported that Lucero sexually assaulted her in her apartment following an encounter at her apartment complex’s pool area. The jury convicted Lucero of sexual assault based on penile penetration and acquitted him of the other charges. The trial court imposed an indeterminate term of ten years to life on sex-offender intensive supervised probation, with ninety days in jail as a probation condition.
On appeal, Lucero argued that the trial court improperly limited his cross-examination concerning whether M.T.’s relationship with her boyfriend was monogamous; admitted improper bad-character evidence arising from his later interaction with police; compelled disclosure of a defense investigative report; permitted multiplicitous sexual-assault charges; and allowed improper closing argument. He also asserted cumulative error.
The Court’s Holding
The Colorado Court of Appeals affirmed. It held that the court did not abuse its discretion by excluding testimony about the boyfriend’s unilateral belief that the relationship was monogamous. Because the defense had not elicited evidence that M.T. knew or shared that understanding, the boyfriend’s belief alone was not relevant to M.T.’s alleged motive to fabricate. The defense was otherwise allowed to present its theory that M.T. falsely claimed assault to protect her relationship.
The division found two errors but held both harmless. Lucero’s antagonistic demeanor during a separate, post-assault police encounter was not intrinsic evidence under Rojas and did not satisfy CRE 404(b). The court also erred by requiring disclosure of the defense investigative report because the defense had not used the report to impeach the witnesses whose testimony was at issue. Neither error warranted reversal, however, given the limited prejudice, the defense’s cross-examination, and the jury’s split verdict. The remaining unpreserved claims did not amount to plain error, and the combined errors did not deprive Lucero of a fair trial.
Key Takeaways
- A witness’s belief that a relationship was monogamous does not by itself establish the complainant’s motive to lie without evidence that the complainant knew of that belief.
- Post-offense conduct at a different location is not intrinsic evidence merely because it occurred near the charged crime in time and place.
- Defense work product is not waived simply by questioning a witness about information learned during an investigation; waiver under People v. Small requires use of the report to impeach the witness with that witness’s prior statements.
Why It Matters
The opinion applies Colorado’s post-Rojas intrinsic-evidence framework strictly, while illustrating that erroneous admission of character evidence may still be harmless where the evidence did not affect the verdict. It also limits compelled disclosure of defense investigation materials absent actual impeachment use.
