A YCSO K-9 unit conducted a traffic violation stop of a vehicle on I-40 eastbound last night, only to find 56,000 fentanyl pills. During a search (based on the K9’s alert), the deputy located 3 fire extinguishers in the vehicle. Based on the interviews with the occupant and suspicious circumstances, the Deputy removed the extinguishers from the vehicle. He then deployed his K9 partner Maximus who “alerted” to the odor of narcotics. Based on the dog’s alert, the deputy confiscated the evidence and opened the extinguishers to find the pills inside. The driver was arrested and booked into the Yavapai County Jail.
