In a case in which a couple was arrested for killing their 4-year-old second daughter by ingesting a harmful chemical substance, the Metropolitan Police Department suspected that the husband's sister, who died six years ago in 2018, was also killed by ingesting the same substance. He was re-arrested.
The Metropolitan Police Department is investigating the matter, suspecting that there was some trouble over heritage.
The suspects who were rearrested were Kenichi Hosoya (43), a company executive from Taito Ward, Tokyo, and his wife Shiho Hosoya (37).
The two were arrested in February last year for murdering their second daughter, 4-year-old Miki, by forcing her to ingest ethylene glycol, a harmful chemical found in car antifreeze, in March last year.
Six years ago, in April 2018, Kenichi's older sister Minako Hosoya (41 at the time), who lived on a different floor of the same apartment complex, suddenly died, and the Metropolitan Police Department is investigating the circumstances surrounding her death. I was there.
As a result
, ``ethylene glycol'' metabolites were detected in Minako's organs
, and the suspect couple had a history of purchasing the chemical at the time, so the
Metropolitan Police Department determined that they had her ingest it in some way and murdered her. On the morning of the 6th, he was arrested again on suspicion of murder.
The Metropolitan Police Department believes that there was a dispute over the inheritance of Kenichi's father, who ran a hotel, etc., and the management rights of the company, and is working to uncover the full story.
