An unusual autopsy case of a victim stabbed during sadomasochistic prostitution

A 29-year-old male who lived alone was found dead with his back leaning against the wall of his room. He had been stabbed in his abdomen with a survival-type knife. The victim's mouth was plugged with a pink-colored glove and was sealed with packing tape. His wrists were tightly tied behind his back with the same type of packing tape. The cause of death was diagnosed as hemorrhage from the right common iliac artery and vein. Due to the strange circumstances of the crime scene, the police initially considered the possibility of homicide by a group of assassins. Two months later, the police arrested a male suspect who was a member of a vice racketeer. The victim was characterized as a masochist and bisexual. He often hired the male suspect to perform sadomasochistic activities. On the day of the crime, the victim prepared a survival-type knife and packing tape himself to experience fear and pain more strongly. The victim hoped to use the knife to increase sexual excitement. In this case of sadomasochistic prostitution leading to death, the legal issues of homicide for money, malicious request of injury by the victim and accidental death were involved.
