TOKYO: Murder detectives were on Monday investigating the case of a young nurse whose corpse was sent by parcel post across Japan in a box that claimed to contain a doll. The body of Rika Okada was found in a storage lock-up in Tokyo. Investigators also found the 2-meter box in which it had been transported from the southern city of Osaka, reports said. The delivery service that ferried the package—marked with the Japanese word for “doll”—400 kilometers (230 miles) to the capital had been paid in Okada’s own name. The bill for the lock-up’s short-term rental had been settled using her credit card. The body of the 29-year-old, who had been missing since late March, had more than a dozen stab wounds, local media reported, but no defensive injuries on her hands or arms.
