In March 2021, a woman in Aomori, Japan called emergency services and delivered a chilling message. "I stabbed my boyfriend."

When police arrived, they found 30-year-old Kyohei bleeding from a severe neck wound. But the most heartbreaking discovery was made inside another room.

Four terrified children were hiding together, listening to everything unfold.

The Perfect Family

From the outside, Sakiko and Kyohei seemed happy. Both were single parents who had found love again and built a blended family together.

They were raising four children, sharing family photos online, and appeared to be creating a new life together. But behind closed doors, their relationship was slowly falling apart.

When They Drank

Friends and neighbors rarely saw the darker side of their relationship. According to investigators, both became different people when alcohol was involved.

Arguments turned into screaming matches. Police had previously been called to the home.

There were also allegations of domestic violence and repeated conflicts that the children witnessed firsthand. Then one night, after drinking together for the first time in a while, everything exploded.

Suspicious

"Was alcohol the cause, or did it expose a relationship that had already been breaking apart for years?"

After stabbing Kyohei in the neck with a bread knife, Sakiko did something investigators could never fully explain. Instead of immediately calling for help, she took out her phone and began recording.

Later, she claimed she acted in self-defense. Prosecutors argued it was an act of rage.

The recording became one of the most important pieces of evidence in the case.

Final Thoughts

The court ultimately rejected the claim of self-defense and sentenced Sakiko to prison.

But the people most affected were neither the victim nor the defendant. They were the four children hiding behind a closed door that night.
