A former senior Aum Shinrikyo member was sentenced Sept. 17 to 14 years in prison for designing a nerve gas laboratory and building the spraying device used in the June 1994 nerve gas attack in Matsumoto, Nagano Prefecture.

According to the Tokyo District Court ruling, Kazumi Watabe, 38, helped kill seven people and injure 144 others in the Matsumoto attack by designing a machine to spray sarin nerve gas. Between November 1993 and December 1994, Watabe plotted to murder an unspecified number of people by designing a laboratory to produce intermediate chemicals to synthesize sarin, the ruling said.
