In a case in which a couple living in Tokyo were arrested for murdering their 4-year-old second daughter by ingesting harmful chemicals, the mother appears to have been taking psychotropic drugs on a regular basis that were detected in the second daughter's body. This was revealed through interviews with people involved in the investigation. The Metropolitan Police Department is investigating the suspect, suspecting that he may have ingested something he had purchased himself.
In March 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 harmful chemicals contained in car antifreeze. He was arrested on the 14th for killing him by ingesting the substance ``ethylene glycol'' and the psychotropic drug ``olanzapine.''
In response to the investigation, suspect Kenichi has denied the charges, and suspect Shiho has remained silent.
Subsequent investigation revealed that Shiho was believed to have been taking olanzapine on a regular basis, and when the Metropolitan Police Department searched his home in August last year, the pills were seized, according to investigators and the Tokyo Metropolitan Government. got it.
The suspect couple had been purchasing these drugs over the Internet for about a year, and the Metropolitan Police Department is investigating the possibility that they may have ingested the drugs they had purchased themselves.
Meanwhile, it has been confirmed that Kenichi's older sister, who died six years ago, appeared to have ingested ``ethylene glycol,'' and we will also investigate this connection.
