Colo.2020Background
- Sandra Archuleta cared for her four‑month‑old grandson for a week; the child was healthy when dropped off but returned hours later unresponsive and died the next day. Autopsy showed multiple injuries (chemical burns, torn frenulum, several broken ribs, apparent pinch marks), pneumonia, dehydration, and bloodstream infection.
- Prosecutors charged one count of child abuse resulting in death under Colo. Rev. Stat. § 18‑6‑401(1)(a), alleging alternative theories: causing injury, permitting an unsafe situation, or engaging in a pattern of conduct that resulted in death.
- Trial evidence (including the coroner) linked multiple discrete injuries and neglect together as a chain of events that produced infection, dehydration, and death; prosecutors argued the injuries collectively caused the death.
- Archuleta asked the court to compel the prosecution to elect a theory and to give a "modified unanimity" instruction requiring jurors to agree on the same act(s) establishing the offense; the trial court denied both requests but submitted interrogatories.
- The jury convicted; the Colorado Court of Appeals reversed, holding a modified unanimity instruction was required because the charging document and evidence presented multiple alternative methods/acts.
- The Colorado Supreme Court granted certiorari, reversed the court of appeals, and held no modified unanimity instruction was required because the prosecution tried the case as a single transaction and there was no reasonable likelihood jurors disagreed about which act caused the death.
Issues
| Issue | Plaintiff's Argument (People) | Defendant's Argument (Archuleta) | Held |
|---|---|---|---|
| Whether a modified unanimity instruction was required where the child‑abuse statute lists alternate means and the prosecution presented multiple discrete injurious acts | Prosecution: No instruction required because it prosecuted a single continuous criminal transaction; when evidence supports a single pattern causing death, jurors need not unanimously agree on the same underlying act | Archuleta: Instruction required because the charge and evidence presented multiple discrete acts/alternative statutory theories any one of which could have supported conviction, so jurors must agree on which act(s) establish guilt | Court: No modified unanimity instruction required—evidence and argument treated the conduct as one transaction causing death and there was no reasonable likelihood jurors disagreed on which act caused death; conviction reinstated on the single count and case remanded for remaining issues |
