Three men suspected of dismembering and barbecuing the remains of their victim were being held by authorities in Japan, police and reports said Thursday. Police said the trio used a hammer to cut up Kazuyuki Kobayashi, before grilling parts of his body and getting rid of it in mountains in rural Japan. Broadcaster TV Asahi said two of the men had confessed to killing Kobayashi and stewing some of his flesh in a curry, in an effort to hide the smell. Tasuku Shimaoka, 34, Keita Yoshida, 30, and Koji Kawamura, 40, were arrested last week on charges of dismembering Kobayashi, who had been missing for about three years, a police spokesman said. It is common for Japanese police to arrest suspects on lesser charges initially in order to extend the time they are allowed to keep them in custody. Media reported Kobayashi\'s body had been stored in a warehouse refrigerator in Tokyo before being taken to Niigata in the country\'s north. \"The suspects conspired between July and August of 2011 and used a hammer-like object to destroy (Kobayashi\'s body). They then cooked the flesh on a barbecue grill,\" the spokesman said. Local reports said there had been a dispute over money. Yoshida has admitted all charges against him, Kawamura has confessed to some, while Shimaoka is maintaining his innocence, police said.
