Utah Court of Appeals
Can medical examiner testimony without reasonable medical certainty support a bindover? State v. Merrill Explained
Summary
Trevor Merrill was charged with criminal homicide, child abuse homicide, and reckless endangerment after his three-and-a-half-month-old son died while co-sleeping between Merrill and the child’s mother. Medical examiner testified that positional asphyxia was the most likely cause of death, though he certified the cause as undetermined due to other possible factors.

Analysis
The Utah Court of Appeals addressed a critical question regarding the admissibility of medical examiner testimony in preliminary hearings in State v. Merrill. The case arose from the tragic death of a three-and-a-half-month-old infant during a co-sleeping arrangement.
Background and Facts
Trevor Merrill went to sleep with his infant son and the child’s mother, Echo Nielsen. The infant was positioned between the adults on his back. When Merrill awoke, the infant was not breathing and was found face-down. The medical examiner, Dr. Leis, testified that the most likely cause of death was positional asphyxia, but certified the cause and manner of death as undetermined because he could not rule out other possibilities like aseptic meningitis with medical certainty.
Key Legal Issues
Merrill challenged the bindover on multiple grounds, including that Dr. Leis’s testimony should have been excluded because it lacked reasonable medical certainty. He argued this standard was a threshold prerequisite for admissibility. Additionally, he contended there was insufficient evidence of causation and that co-sleeping did not constitute child abuse or reckless endangerment.
Court’s Analysis and Holding
The court rejected Merrill’s arguments, citing State v. Talbot and State v. Jarrell as precedent for admitting medical testimony based on probability rather than certainty. The court emphasized that expert opinions may be admitted when based on the witness’s best judgment from training and experience, even if expressed in terms of probability rather than certainty. The court noted that “uncertainties regarding the cause of death should be left for the fact-finder to resolve at trial.”
Regarding the child abuse charges, the court found sufficient evidence where Merrill had previously experienced an infant death during co-sleeping but continued the same sleeping arrangement. This created a substantial and unjustifiable risk constituting a gross deviation from ordinary care standards.
Practice Implications
This decision clarifies that medical examiner testimony need not meet a reasonable medical certainty standard to be admissible at preliminary hearings. Practitioners should focus challenges on whether opinions are speculative rather than demanding medical certainty. The court’s analysis also demonstrates how prior similar incidents can establish the requisite mental state for criminal negligence charges, even in cases involving parental conduct that might otherwise be considered ordinary.

Limited deference to the lower court’s bindover decision for mixed questions of law and fact
Practice Tip
