In a case in which the parents were arrested for killing their 4-year-old second daughter by ingesting harmful chemicals, they had purchased the chemicals multiple times for about a year before the second daughter's death, but after her death, the parents were arrested. Interviews with investigators revealed that there was no evidence that the item had been purchased. The Metropolitan Police Department is investigating the details of the purchase, including its purpose and usage.
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, 4-year-old Miki, 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.''
According to the investigation so far, the Metropolitan Police Department searched her home in August last year and analyzed the smartphones and computers that were confiscated, and found that Miki had been using ``ethylene glycol'' and ``olanzapine'' multiple times over the internet for about a year before her death. I know that you purchased it.
Of these, ``ethylene glycol'' had been purchased about a month ago and a few days ago, but interviews with investigators revealed that there was no trace of it being purchased after his death.
Regarding ``ethylene glycol,'' Shiho gave an explanation to a voluntary inquiry before his arrest to the effect that ``I don't remember for sure, but if I had bought it, I would have bought it.''
The Metropolitan Police Department is investigating the details of the time, including the purpose of the purchase and how it was used.
In response to the investigation, suspect Kenichi has denied the charges, and suspect Shiho has remained silent.
