505 P.3d 689
Idaho2022Background
- April 26, 2018: Ochoa drove from a parking lot into the path of a northbound motorcycle in Nampa; the motorcyclist was transported to the hospital and later died from injuries and massive blood loss.
- State charged Ochoa with misdemeanor vehicular manslaughter (I.C. § 18-4006(3)(c)). Trial occurred May 8, 2019; jury convicted Ochoa and magistrate sentenced her.
- Victim’s toxicology showed methamphetamine, amphetamines, methadone (and later-disclosed 441‑page report suggesting possible alcohol/marijuana); a small bag of heroin was also found on the victim.
- Magistrate excluded testimony about the victim’s controlled‑substance toxicology as minimally probative and unfairly prejudicial (I.R.E. 401, 403); denied a last‑minute continuance; admitted Dr. Groben’s testimony about cause of death based on medical records under I.R.E. 703.
- District court (on intermediate appeal) vacated and remanded, finding errors on those three evidentiary/continuance rulings; the Idaho Supreme Court granted review and reversed the district court, reinstating the conviction.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Ochoa) | Held |
|---|---|---|---|
| Admissibility of victim toxicology | Toxicology is relevant to comparative negligence/causation and should be admitted | Toxicology was relevant to show victim impairment; exclusion deprived defense of evidence | Exclusion was proper: presence of drugs alone, without expert foundation proving impairment, was minimally probative and unfairly prejudicial (I.R.E. 401, 403); magistrate did not abuse discretion |
| Denial of last‑minute continuance | Delay largely due to defense; State disclosed substance results earlier; defendant failed to show prejudice or a reasonable probability of a different result | Late disclosure of full 441‑page report prevented fair preparation and investigation; Brady issue | Denial proper: defendant knew substance results months earlier; mere claim that more investigation might help insufficient to prove prejudice or Brady violation |
| Admission of Dr. Groben’s testimony (reliance on treating physicians’ records) | Dr. Groben properly relied on medical records and formed his own opinion; I.R.E. 703 permits such expert reliance | Testimony was hearsay conduit of other physicians’ findings and should have been excluded | Admission proper: Dr. Groben explained his methodology, relied on records as facts/data experts in his field reasonably rely upon, and reached his own conclusion on cause of death under I.R.E. 703 |
| Due process (right to confront/examine toxicology evidence) | — | Excluding toxicology and denying opportunity to develop it violated due process and right to present a defense | Argument waived: defendant failed to brief or argue the constitutional claim with authority; not preserved for appeal |
