While on routine patrol, you notice a car with two people inside parked behind a business that has closed for the evening. You've recognized this to be a high-crime area that has had several burglaries recently. As you pull behind the car, you shine your spotlight on the vehicle and notice the passenger in the front seat leaning down between the seats. You order the individuals out of the car and place them both in handcuffs for protection. After frisking them for weapons, you approach the passenger side of the vehicle and notice a six-pack of beer on the front floorboard. As you move the carton, you find a small container of what appears to be a controlled substance. You conduct a preliminary field test, and the substance tests positive for cocaine.
