The car braked as it approached a slower vehicle, but only the left brake light came on. Noting the faulty right brake light, Darisse activated his vehicle’s lights and pulled the car over. Vasquez sat behind the wheel, and D lay across the rear seat. Darisse gave Vasquez the warning ticket. Darisse had become suspicious, and the two gave inconsistent answers about their destination. Darisse asked whether the men were transporting various types of contraband. Darisse asked whether he could search the car. Vasquez said he had no objection, but told Darisse he should ask D because D owned the car. D gave his consent. In the side compartment of a duffle bag, Darisse found a sandwich bag containing cocaine. Both men were arrested. The State charged D with attempted trafficking in cocaine.
