R: 3 / I: 3Revenge During Fetish Game
Source: Rechtsmedizin, Burkhard Madea Hrsg. (German Forensic Medicine Textbook by Burkhard Madea MD). Germany. Case from 2004.
Auto-translated. 24 year old man had intentionally caused the death of his 28 year old domineering gay partner. During the strangulation fetish session he was acting as a safe spotter. But was on purpose strongly encouraging the 28 year old to push it further and further, while hand and mouth “stimulating” his partner's penis so he would not want to stop. And when finally his partner went too far and had passed out, he just stood and watched him getting strangled to death. And immediately right after that calling police to report accidental death and that he had found him like that when he came to his home.
But police got suspicious. And upon further interrogation the 24 year old had finally admitted of planning death of his gay lover. As a self-defense against his partner sexually using him for months in very domineering degrading rough way, like a s-ex toy slave. With his hands being tied behind his back on many occasions. And blackmailing him by threatening to reveal certain legal issues from the 24 year old's past to his government job employer, if he dared to leave him.
On scene photos the deceased can be seen as he was found (right after the paramedics had taken away the life detecting sensors from his chest). There was large dripping stain of his dried sperm on the mirror. Indicating large volume ejaculation before passing out. A metal kitchen tray was under him, so his sperm would not get on the carpet. Corpse’s penis also kept some of its erect status. A condition known as "rigor erectus"/death erection.
