On April 15, 2001, people in a "support and education group" from other cities came to Dalian Detention Center and called a secret meeting with the female police unit, making plans for further persecution of the female Dafa practitioners who refused to be "reformed." In the evening, the guards started torturing the practitioners, requiring them to curse our Teacher. As a punishment for practitioners who refused to do so, the guards forced practitioners to stand in a severe and painful position, with their hands clasped behind their heads and at the same time bowing down 90 degrees. Anyone found not standing this way to the guards' satisfaction was beaten and kicked. Some of the women guards kicked the practitioners with their high heels shoes. Those practitioners who still refused to follow the instructions were shocked on the neck with electric batons. Many practitioners were shocked to the point of sustaining bruises all over their bodies. Early the next morning, after enduring the overnight torture, the guards ordered the severely tortured Yu Lixin and Xue Nan to clean up a room on the fifth floor. All the rooms in the detention center, except this one room, have iron parapets enclosing the windows. Soon Yu and Xue were seen falling from the window. Yu Lixin died on the scene.
