"Mulvey said a legitimate shipment of dried fruit was behind the packages and that the drugs were likely loaded near a set of doors so as to be easily accessible to smugglers. The ship was headed next to the Belgian city of Antwerp.
Mulvey said it was not yet clear whether the drugs were intended to remain in the US or to continue on to Europe."

I am inclined to agree with the Antwerp Theory. But who knows.
