Police got a call just after midnight on May 15th, 2021, that Yui Inoue had destroyed her ex-husband’s electronics with a meat cleaver after they had fought.

Police went to her apartment and saw that her children, 7-year-old Kai Inoue and 9-year-old Mia Inoue, were sleeping.

After the police left, Yui took the meat cleaver and used it to end both of her kids’ lives.

Police went to her home and found the kids dead.

At her sentencing on May 2nd, 2025, she told he court, “My children are not dead. My parents have them. They are spending their time with my parents.”
