Excerpt from wikipedia below. Makes me fucking sick.
> According to their statements at their trial, the four of them raped her, beat her with metal rods and golf clubs, introduced foreign objects including a light bulb into her vagina, made her eat cockroaches and drink her own urine, inserted fireworks into her anus and set them off, forced Furuta to masturbate, cut her nipple with pliers, dropped dumbbells onto her stomach, and burned her with cigarettes and lighters. One of the burnings was punishment for attempting to call the police. It was also stated that some time after the first acts of torture, she became unable to drink water, which would cause her to vomit whenever she attempted to do so. At one point her injuries were so severe that according to one of the boys it took more than an hour for her to crawl downstairs to use the bathroom. They also related that "possibly a hundred different people" knew that Furuta had been imprisoned there, but it is not clear if this means they visited the house at different times while she was imprisoned there, or themselves either raped or abused her. When the boys refused to let her leave, she begged them on several occasions to "kill (her) and get it over with".
>On January 4, 1989, using a loss at mahjong solitaire, the four beat her with an iron barbell, poured lighter fluid on her legs, arms, face and stomach, and set her on fire. She died later that day of shock. The four boys claimed that they were not aware of how badly injured she was, and that they believed she had been malingering.
>On January 5, the killers hid her corpse in a 55-gallon drum filled with concrete; the perpetrators disposed the drum in a tract of reclaimed land in Kōtō, Tokyo.
