Presumption of a suspect based on the skin fragment attached the rope.
An eight-year-old girl (second-year of elementary school) was strangled in an irrigation canal near her house and was left unconscious. The body of a male who hanged himself to death was discovered on the next day. The hanging mark on the neck of the man and the ligature mark on the neck of the girl were caused by double nooses of a rope, the width of the rope mark was nearly the same, and similar Zwischenkammblutung (subcutaneous bleeding in the middle of the rope mark) was observed in both cases. Therefore, we evaluated whether the marks were caused by the same rope. As a result, the DNA type of the skin fragment (keratinized epithelial cells) attached to the rope used by the man to hang himself was identical to that of the girl. On the basis of this evidence, the man who hanged himself to death was presumed to be the suspect who strangled the girl.
