My 4-year-old second daughter died from poisoning. There was no evidence that she had purchased any chemical substances after she died.

In March of last year, Kenichi Hosoya (43), a company executive in Tokyo's Taito Ward, and his wife Shiho Hosoya (37) exposed their second daughter to poisonous chemicals contained in car antifreeze. He was arrested on suspicion of murdering her by ingesting her with ``ethylene glycol'' and the antipsychotic drug ``olanzapine''
