largest marijuana bust

Costa Rican agents made the largest marijuana bust in the Central American nation's history, seizing 4.85 tons of the drug found in an abandoned boat, police said Saturday.
The marijuana was discovered Friday during a patrol with the U.S. Coast Guard off the country's Pacific coast, Costa Rican police said in a statement.
The ship's crew fled, abandoning their 48-foot-long boat near the border with Panama, where they appear to have fled, police said. No arrests have been made.
