Authorities in a southern Arizona city near the Mexico border have found two feces-covered bales of marijuana tied to a rope feeding into a sewer system.
Nogales police say public works employees hauled out an estimated 39 pounds of pot while investigating a clogged sewer line Wednesday.
Investigators told the Nogales International newspaper that the bales were smaller than the size of a suitcase and tied to 900 feet of rope in a narrow pipe that connects systems in the U.S. and Mexico.
Police Lt. Carlos Jimenez says it's the first time they've discovered marijuana tied to a rope they believe smugglers were planning to maneuver through the line.
Police say a search at the Rio Rico sewer plant, where the feed ends, did not turn up more drugs.
The drugs' street value was estimated at more than $20,000.
