Background

Officers responded after Tremayne’s vehicle left the road and entered a residential front yard. They found Tremayne unresponsive and slumped across the passenger seat inside the locked vehicle. Officers broke windows to reach and remove him, and one officer saw a blue pill on foil near the center console. Believing Tremayne had overdosed on fentanyl, another officer administered Narcan.

While paramedics evaluated Tremayne, officers found a device used to ingest narcotics outside the driver-side door and a bag containing five additional blue pills on the front passenger seat. The State charged Tremayne with possession of a controlled substance, possession of drug paraphernalia, and a persistent-violator enhancement.

Tremayne moved to dismiss under Idaho’s overdose-immunity statute, Idaho Code § 37-2739C(2). After the district court denied the motion, he conditionally pleaded guilty to controlled-substance possession while preserving his right to appeal. The State dismissed the remaining charges.

The Court’s Holding

The Idaho Court of Appeals held that Tremayne was not entitled to statutory overdose immunity because his medical emergency and need for assistance were not the sole cause of the discovery of the contraband. The court therefore affirmed the district court’s denial of his motion to dismiss and his judgment of conviction.

Applying the Idaho Supreme Court’s interpretation in State v. Soliz, the court treated the statute’s phrase “as a result of” as requiring the medical emergency and need for assistance to be the sole cause leading to the evidence. Tremayne’s driving behavior—leaving the road and entering a residential yard—combined with his medical emergency to bring officers to the vehicle and lead to the contraband’s discovery.

Key Takeaways

  • Idaho’s overdose-immunity statute applies only when the drug-related medical emergency and need for assistance are the sole cause of the discovery of the evidence supporting the covered charge.
  • Immunity did not apply because both Tremayne’s medical condition and his driving behavior led officers to discover the fentanyl and paraphernalia.
  • The court affirmed Tremayne’s conviction for possession of a controlled substance following his conditional guilty plea.

Why It Matters

The decision applies the Idaho Supreme Court’s narrow construction of overdose immunity in State v. Soliz. A defendant’s need for emergency medical assistance does not bar prosecution when an independent circumstance, such as dangerous or unusual driving, also leads law enforcement to the evidence.
