Japanese police said they have found three bodies under the floor of a house in the industrial city of Amagasaki in Hyogo prefecture. Police sources told the Yomiuri Shimbun the discovery was made after the body of a woman who died last year was found in a drum filled with concrete. Miyoko Sumida, 64, has been charged with beating the woman to death. Police said seven people who knew Sumida have disappeared and may have become crime victims. The house where the three bodies were found was reportedly occupied by relatives of Sumida\'s daughter-in-law. Identities of the victims have not been released but sources said it was a man and two women.
