Arizona Department of Public Safety troopers caught about 20 pounds of cocaine on Feb. 4. The sedan crossed through a port of entry in Nogales earlier in the day, but a trooper grew suspicious during a traffic stop and a drug-sniffing dog alerted to the load. Troopers at DPS' Tucson office found the cocaine hidden in a compartment running down the center of the vehicle. Video by Curt Prendergast/Arizona Daily Star.
