In 2003, the Shanghai textile vocational school students in section Yina, suffered in the dormitory complex with Qing Liu school a faculty of rape, in the segment against the process, Liu died. Splash of semen found at the scene, Liu's two testicles burst, the two testicles forensic Liu bed and on the spot by the mechanical rupture, resulting in cardiac arrest and Liu's death. District Intermediate People's Court ruled that the school violated the provisions of Liu Fan Qing Yina appear in the section of the bedroom, according to statements section, Liu take off her clothes and tried to rape her, her legs together struggling to make the penis has not inserted Liu vagina, the penis was Liu ditch ejaculation in her ass in the process of ejaculation in Liu, she is not prepared to take advantage of its open Ryu and Ryu kick kicked in the crotch, then hands Ryu cover the crotch screams fell fainting on, she immediately reported, the police arrived, Liu had stopped breathing. Forensic examination, there is no section Yina vaginal semen, only secretions, and bed and have a splash of semen on the ground, the scene tussle marks belong to Liu Fan Qing attempted rape, in the tussle in the men and women, Liu was kicking leg kick with section Yina in the scrotum, caused by bilateral testicular rupture, induced cardiac arrest and died. Section Yina is self-defense, not guilty. Reported to superiors, but after the approval of the Shanghai High Court that the evidence is insufficient, the logic is very reluctant to require intermediate complex survey the scene and forensic Division Kary help women in hospital, a new trial. Division Kary re-survey the scene, read the dossier, but also re-examine the remains of the deceased, made a new inference. Kary Division found that (1) larger size of the scrotum deceased Liu, 6.5 Ã— 8 Ã— 5 cm (width Ã— height Ã— thickness), after bilateral testicular recovery 6 Ã— 7 Ã— 5 cm (width Ã— height Ã— thickness), vas deferens on each side length 12 cm, the characteristic line is easy to blow easily understood by external forces caused by the type of testicular burst. (2) autopsy confirmed bilateral testicular rupture caused by Liu's direction of the force, both before and after the positive force, vas no bruise marks. If the top of the foot or leg kick, testicle should be up and down direction of the force, suggesting that, Ryu's testes should be the woman's positive direction before the rupture force. But the lawyer segment Yina Liu Cao Yandong stressed the scrotum large, was the first open section of a body blow after kicking the process, because physical activity, may cause the scrotum and forth situation. When the scrotum back swing, swing to the bottom ditch testes when the parties happen to be female feet kicked, pushed feet testicles when the trench bottom ass rupture force. Entity from the Forensic simulated situation, the logical inference is possible.
