A Customs and Border Protection drug-sniffing dog at the Port of Nogales alerted to marijuana within the floor of a Chevrolet sedan Sept. 21, 2013. As a result, officers arrested a 42-year-old Tucson woman and seized 22 packages of marijuana weighing more than 102 pounds. The weed had an estimated street value in excess of $46,000.
