An Aum Shinrikyo biologist testified at cult founder Shoko Asahara's trial Thursday that he did not think much about the sarin produced at an Aum facility when he was first shown a sample.
Taking the stand for Asahara's defense team at the Tokyo District Court, Seiichi Endo, 38, said he was shown the sample in a triangular flask in November 1993 by cult chemist Masami Tsuchiya.
Endo said this occurred in a visit to Tsuchiya's lab at the Aum complex in Kamikuishiki, Yamanashi Prefecture. He said he merely thought the substance was a poison gas.
