BOSTON – A U.S. Customs and Border Protection dog sniffed out something unusual in luggage from a traveler returning from Africa – mummified monkeys. The passenger returning from a visit to the Democratic Republic of Congo reported that the luggage contained dried fish, but an inspection at Boston Logan Airport revealed dead and dehydrated bodies of four monkeys, agents said. The traveler said he brought the monkeys into the U.S. for his own consumption, Ryan Bissette, a CPB spokesperson, said Sunday.
