Falun Dafa practitioner Zhang (complete name is unknown), female, 49 years old, is from Tanggu District, Tianjin. She is a retired employee of Tianjin Harbor Department. Police caught her and forcibly sent her to a so-called "transformation class" held in a drug rehabilitation center on January 15, 2001. Over 100 practitioners were arrested at the same time. Since Zhang persisted in practicing Dafa and definitely refused the transformation, she was sentenced to a one and a half year term of labor re-education at the end of March. Around 5 am on May 11, Zhang suddenly fell down while cleaning. She was sent to a hospital and died after ineffective rescue. Doctors informed her family that she died of "a sudden heart attack".
