A 49-year-old man who was serving an 18-year prison term for killing a 17-year-old girl in Hitoyoshi, Kumamoto Prefecture, in May 2014, committed suicide in his cell last week.
According to police and prison authorities, Wataru Akaishi hanged himself by tying his underwear around a bar in his cell and formed a noose, Sankei Shimbun reported. He was found hanging by a guard making the rounds on Aug 18 and died in the Kumamoto prison hospital on Aug 20.
Akaishi was convicted in June 2014 of the murder of missing high school girl Mayuko Arakawa. Police found her body after Akaishi, already under arrest for sexually assaulting an Okinawan woman in Aichi Prefecture, confessed to killing her and dumping her body on the mountain.
Police later discovered that Akaishi had befriended Arakawa on the Internet and made arrangements to meet her. Akaishi rented a car and came to Hitoyoshi in early May and stayed in a business hotel.
Akaishi met Arakawa on May 4 -- the day she disappeared -- and checked out of his hotel the same day.© Japan Today
