Summary
This Wyoming Supreme Court opinion addresses consolidated appeals by two defendants challenging the district court's denial of their motions to suppress marijuana found in a rental car trunk following a traffic stop. The court analyzes whether the initial stop, subsequent detention, canine sniff, and vehicle search complied with state and federal constitutional protections against unreasonable searches and seizures. Additionally, the court resolves a standing issue regarding whether a passenger has the right to challenge the constitutionality of the stop and search. Ultimately, the court affirms the lower court's decision, finding probable cause and reasonable suspicion justified the police actions.

Questions Presented
- Whether the initial traffic stop was justified under the Wyoming and Fourth Amendments
- Whether the detention and questioning were reasonable
- Whether the canine sniff detention was lawful
- Whether the search of the trunk was supported by probable cause
- Whether a passenger has standing to challenge the stop, detention, and search
- Whether a passenger loses standing by denying ownership of the trunk’s contents
Holdings
- The stop was justified because the officer observed a traffic violation; the stop did not violate Article 1, § 4 of the Wyoming Constitution nor the Fourth Amendment.
- The detention and questioning were reasonable in scope, duration, and intensity and therefore did not violate constitutional rights.
- The brief detention of the appellant during the dog sniff was justified by articulable suspicion and was reasonable in scope.
- The dog’s alert near the trunk gave the officer probable cause to search the trunk, and the search was lawful.
- A passenger who is lawfully present in a vehicle has a reasonable expectation of privacy and therefore standing to challenge the stop, detention, and search.
- A passenger who merely states she did not put anything in the trunk has not unequivocally abandoned ownership; therefore she retains standing to challenge the search.
