Body of Japanese woman Rika Okada mailed across country in a 'doll' box

Japanese detectives have opened a murder investigation after the body of a young woman was found in a storage locker after being mailed 230 miles from Osaka to Tokyo in a 6.5-foot box labeled "doll." Rika Okada had been missing since late March. According to the company that delivered the package, the order was paid in Okada's name. The 29-year-old's credit card was also used to rent the storage locker where her body was found. Okada's body was found with more than a dozen stab wounds, but authorities say there were no defensive wounds to indicate a struggle. Prior to disappearing, Okada posted on Facebook that she was going to visit an old friend. Police have refused to confirm a report that a woman used Okada's passport earlier this month to leave the country and fly to Shanghai.
