In 2001, Boston police officers received a tip that a Kmart employee, Thomas Wright, was engaging in suspicious activity. The informant reported that Wright repeatedly received phone calls at work, after each of which he would be picked up in front of the store by a blue sedan, and would return to the store a short time later. The police set up surveillance in the Kmart parking lot and witnessed this precise sequence of events. When Wright got out of the car upon his return, one of the officers detained and searched him, finding four clear white plastic bags containing a substance resembling cocaine. The officer then signaled other officers on the scene to arrest the two men in the car-one of whom was petitioner Luis Melendez-Diaz. The officers placed all three men in a police cruiser.

During the short drive to the police station, the officers observed their passengers fidgeting and making furtive movements in the back of the car. After depositing the men at the station, they searched the police cruiser and found a plastic bag containing 19 smaller plastic bags hidden in the partition between the front and back seats. They submitted the seized evidence to a state laboratory required by law to conduct chemical analysis upon police request.
