Survivors of Aum Shinrikyo's criminal mayhem and the next of kin of its victims said Monday that the case is not closed even though the Supreme Court issued a ruling that effectively ended 16 years of investigations and trials.

By rejecting the appeal of condemned cult killer Seichi Endo, the top court effectively finalized his sentence. Endo was convicted of making the sarin used in both the 1995 Tokyo subway gassing and the deadly 1994 attack in Matsumoto, Nagano Prefecture.

At a news conference in Tokyo, Shizue Takahashi, 64, who lost her husband Kazumasa, 50, a senior official at Kasumigaseki subway station, in the 1995 sarin attack, expressed her scorn for the cult after hearing the top court's decision Monday.
