The case of Zhu Ling has hit the headlines again recently. Zhu was a promising chemistry student at Beijing's prestigious Tsinghua University before she was left paralysed after being poisoned with thallium, a toxic chemical, nearly two decades ago. The renewed interest in her tragic case was ignited by a similar poisoning case in April that led to the death of a Fudan University student.
Zhu Ling, born in 1973, is the victim of an unsolved 1995 thallium poisoning case in Beijing, China. She survived the poisonings but suffered serious neurological damage and permanent physical impairment. One roommate of Zhu Ling was questioned and later released during the investigation.The Beijing police closed the case in 1998 without making any arrest.The case drew national media attention in China. Zhu Ling's supporters have since been urging the Chinese government to re-examine the case through online campaigns.
