2019 COA 64
Colo. Ct. App.2019Background
- Sandra Archuleta cared for her four‑month‑old grandson for a week; the child was healthy at drop‑off and later returned unresponsive and died the next morning.
- Autopsy showed dehydration and bacterial infection (sepsis) as cause of death, with contributing injuries: chemical burns to face/mouth, a torn frenulum, and broken ribs.
- Prosecution charged a single count: child abuse resulting in death, alleging the conduct occurred during the week Archuleta cared for the child and argued three alternative theories under § 18‑6‑401(1)(a): (1) causing injury, (2) permitting placement in a dangerous situation, or (3) a continued pattern of conduct.
- At trial the prosecution presented evidence of multiple discrete acts/injuries and invited conviction under any of the three alternative theories; the court refused defense requests for a modified unanimity instruction and gave only a general “verdict must be unanimous” instruction.
- Jury returned a general guilty verdict and answered interrogatories that the abuse resulted in death, serious bodily injury, and other injury; Archuleta was sentenced and appealed, arguing failure to secure a unanimous verdict under Colorado’s unanimity statute (§ 16‑10‑108) and constitutional due process.
- The Court of Appeals reversed and remanded for a new trial, holding that a modified unanimity instruction (or prosecutorial election) was required because evidence of multiple discrete acts supported non‑continued‑pattern theories and the prosecution did not elect the act(s).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the trial court erred by failing to require election or give a modified unanimity instruction under § 16‑10‑108 when prosecution presented multiple discrete acts supporting a single count | People argued no reversible unanimity error because interrogatories and sufficient evidence supported the verdict | Archuleta argued jurors may have convicted on different acts so unanimity on specific act(s) was required; trial court should have instructed or required election | Reversed: under Thomas/§ 16‑10‑108, when multiple discrete acts can each constitute the charged offense and there is a reasonable likelihood jurors disagree which act occurred, prosecution must elect or court must give a modified unanimity instruction; here error was not harmless and requires retrial |
| Whether due process (state or federal) independently requires jury unanimity on the specific acts underlying conviction | People and trial court treated the issue as constitutional in part, but argued no due process violation here | Archuleta argued due process requires unanimous verdict on the acts that establish the offense | Court declined to resolve constitutional question (applied statute); special concurrence concluded no due process right to unanimity but agreed reversal was required under the statutory unanimity rule |
