Chiba woman arrested over 89-year-old mother’s 2024 killing
The suspect has denied the allegation to police, who are investigating the possibility of a money dispute.
Chiba police have arrested a 54-year-old woman, Hideko Ishigami, for allegedly killing her 89-year-old mother, Shizuko Ishigami, in their home in Isumi city, Chiba Prefecture. The woman, who works part-time, is suspected of strangling her mother to death by asphyxiation sometime between 2 p.m. and 4:40 p.m. on August 5, 2024. Ishigami denies the allegations and it is unclear why she allegedly killed her mother.
Police found that Hideko Ishigami managed her mother's bank account and had taken more than ¥10 million ($68,000) from it to pay online video streamers. The mother lived alone in Isumi while her daughter lived separately in Mobara. Police discovered that security sensors in the home stopped registering activity after the killing and found her collapsed on the floor of a second-floor bedroom.
An autopsy determined she died from asphyxiation. Police are investigating whether a financial dispute may have led to the killing.
