OSAKA -- An Osaka woman and her brother were arrested Thursday for allegedly killing her husband, dismembering his body with an electric saw and dumping the remains in the sea.
Police found a severed human head in Osaka Bay in November and, through dental records and DNA tracing, identified the remains as those of Matsuo Ishitani, 45, president of an electrical appliance store in Minato Ward, Osaka.
Police officials, who served the arrest warrants early Thursday, had been questioning Ishitani's wife, Yoshiko, 44, and her brother, Yasunori Matsumi, 40, an employee of Ishitani's store, since Wednesday morning.
