18 year old was streaming masturbating on TikTok while hanging himself for greater arousal effect, using a bed sheet for that. Getting so aroused in the process and wanting to experience even a bigger effect, he had fatally stretched both of his feet forward. Putting by this almost a full body weight on his neck. Then he let go of his last support, his hand grabbing the belt. Now putting even more pressure on his neck. Where by his following body reactions to what happened next, looks a lot like his neck got snapped/damaged. Thus making him paralyzed. And by being left helpless limp in the noose getting hanged to death on camera.
At around 1:54 mark you could hear the push up bar above slightly creaking again, from the continued pull of his body weight.
