Mitsuo was a troubled runaway teenager who came from a highly dysfunctional family. He followed a woman who was Tomoki's wife as she pushed her baby in a stroller across a bridge and down in front of the stream. Mitsuo then bludgeoned to death Tomoki's wife and drowned their infant baby. He then raped the deceased woman's body.
