The circumstances giving rise to probable cause in this case were not “unforeseeable and spontaneous.” Those circumstances included investigating previous information from the CI and concerned citizen about defendant, the vehicle, and narcotics trafficking in the area; lengthy surveillance of defendant and the vehicle; reasonable and articulable suspicion that defendant had engaged in a drug deal; and a positive canine sniff of the vehicle. The Court therefore affirms the order suppressing the physical evidence seized from the vehicle.
