CHICAGO - Four men have been arrested and charged with drug possession after police found what they estimated to be million worth of high-grade cocaine hidden inside a shipment of Mexican avocado pulp Friday. "This came right through the border," Chicago Police Commander Wayne Wiberg said Monday while standing in front of still-bundled 2-kilogram bricks of cocaine, each of which had been individually stuffed inside 180 buckets of frozen guacamole. Following up on a tip, police located 308 kilos of cocaine inside the buckets taken from a truck. Police found another 760 tubs of the green glop at a warehouse in a nearby town.
