Charges that Kenji Kamimine (上峯 憲司), a former leader of Hane-gumi, ordered Jo to kill Murai were dismissed by the Tokyo High Court. Jo had claimed Kenji had ordered him to kill any Aum Shinrikyo leaders that he could. It is believed that this was done out of fear of the yakuza's connections to the cult being made public.{{cite news | title = High court clears mob boss of ordering Murai hit | url = http://search.japantimes.co.jp/cgi-bin/nn19990329a5.html | publisher = Japan Times | date = 1999-03-29 | accessdate = 2007-09-17 }}{{Cite news |last=Adelstein |first=Jake |date=2018-07-09 |title=Aum Shinrikyo: The Japanese Killer Cult That Wanted to Rule the World.
