Background
Story County officers stopped Dartangan Leonard’s car after seeing a passenger throw a cigarette from the vehicle. The stop followed a task-force tip that the car was traveling west from Marshalltown with marijuana onboard. During the stop, an officer saw a THC vape pen in the center console. Leonard produced a valid Iowa medical cannabidiol registration card and said the pen contained medical cannabidiol.
Officers removed the vape pen, and a drug dog later alerted near the rear passenger door. Leonard and his passenger had given conflicting accounts of their travel, and Leonard denied that illegal drugs were in the vehicle. A search found more than ten pounds of illegal marijuana products in the trunk. After the district court denied suppression, Leonard entered a conditional guilty plea to possession with intent to deliver marijuana as a habitual offender.
The Court’s Holding
The Iowa Court of Appeals affirmed. Reviewing the suppression ruling de novo, it held that the totality of the circumstances gave officers probable cause to conduct a warrantless automobile search under the federal and Iowa constitutions.
Leonard’s medical cannabidiol card could not itself be used as grounds for probable cause under Iowa Code section 124E.12(9), but the court held that lawful possession of medical cannabidiol did not eliminate probable cause otherwise supported by the evidence. The dog alert was not the sole basis for the search: officers had the tip, conflicting travel accounts, Leonard’s denial of illegal drugs, removal of the known vape pen before the sniff, and an alert away from the vape pen’s known locations. Those facts supported a reasonable belief that evidence of a crime would be found in the car.
Key Takeaways
- A reliable drug-dog alert can contribute to probable cause even though some substances that may trigger an alert can be legally possessed.
- Iowa’s protection against using a medical cannabidiol card as a basis for probable cause does not bar consideration of other circumstances supporting a search.
- Probable cause rested on the combined circumstances, not on the dog alert alone.
Why It Matters
The decision confirms that Iowa’s medical-cannabidiol regime does not make a drug-dog alert legally irrelevant in vehicle-search cases. Courts must assess the entire factual setting, including the alert’s location and other corroborating indicators of criminal activity.
