(Missouri) - A startling discovery was made by FedEx workers in St. Louis. They found two human legs and an arm inside three boxes, station KMBC reported. Workers opened the boxes when one of them started leaking. Kirkwood police said the boxes were on their way from Las Vegas to a suburban St. Louis man who provides doctors with body parts for research. The packages were too damaged to be delivered, so the man had to come pick them up. Because the limbs were shipped across state lines, the FBI and other state agencies got involved. Authorities found the limbs were from a legitimate business and had paperwork to prove they were disease-free. ***** Now that's one thing I would not want to see in My FEDEX Box! Hello!
