Mr. Zhang Weiyun was 62 years old and started practicing Falun Dafa in 1997. He was illegally arrested by police from the State Security Division of the Zhengzhou City Railroad Police Department and was detained. At the time, his blood pressure was as high as 220mm. He was sent to the hospital for emergency rescue many times, but the police still refused to release him. Finally Mr. Zhang was released on medical parole.

Although Zhang Weiyun was released, he was extremely weak and had an unfocused mind, which was the result of being tortured during detention. State Security Agent Wang Zhaoli (male) from the State Security Division of the Zhengzhou City Railroad Police Department often harassed and threatened Mr. Zhang at home. Mr. Zhang's son once warned the police, "My father was already tortured during detention, and cannot be frightened any more. Stop harassing us from now on!" Wang Zhaoli and the other officers never paid attention to his warning. Mr. Zhang's condition worsened and rescue effort failed. He died on October 26, 2005.
