Call to re-examine similar casein 1994 that remains unsolved

AN unsolved case from 1994, where a student at Beijing's Tsinghua University suffered thallium poisoning, is back in the news following the death of a Fudan University student allegedly poisoned by his roommate.

Zhu Ling, now 39 years old, then a chemistry student at Tsinghua, suffered neurological damage that left her unable to take care of herself, besides facial paralysis and the loss of nearly all speech and eyesight.

Her roommate Sun Wei was a suspect but the case was never solved. Jealousy of Zhu's talent and beauty was reportedly the motive of the poisoning.

Sun is believed to be living abroad and married.

Bei Zhicheng, Zhu's high school classmate, is urging police to take another look at the case by disclosing a document found when someone hacked into Sun's e-mail inbox in 2006.

At that time, Sun published an announcement again denying she was the poisoner.

Bei told the Nanfang Daily that the document was two pages of "guidelines on online posting" where Sun encouraged friends and classmates to publish online posts supporting her to prove her innocence.

The guidelines asked what Sun called her "backup team" to publish posts saying things such as "Sun has a very good relationship with her roommate and they never had any conflicts," or "As a close friend to Sun, I know she is not the person to poison her roommate."

Another post that Sun is said to have encouraged friends to post was "I have tried to speak for Sun to prove her innocence for several times but she stopped me. But this time, I cannot bear it anymore that I have to come forward to tell the public that we support her."

The guidelines advised: "You should publish the posts slowly every day and should avoid commenting on each other's posts. But when other people leave comments, you should make fast response to them.

"If the journalists want to arrange an interview with you, never trust their sweet words. The best solution is that you refuse to be interviewed."

Zhu lost her hair within several days and suffered stomach pains at the end of November 1994. She was in hospital for a month but doctors couldn't find the reasons for her ill health.

In March 1995, about 10 days after she returned to Tsinghua, Zhu was again admitted to hospital. She fell into a coma for five months. Doctors were still unable to diagnose her disease.

Zhu's classmates and Bei, who was then a Peking University student, sent e-mails describing her condition to experts across the world and they received about 3,000 replies with a third of them mentioning thallium poisoning.

A Beijing medical agency said the amount of thallium in her body would have been enough to kill her. Zhu's parents alerted the police.

Sun was a suspect as it was believed she had access to thallium and was close to Zhu.

Several days after police launched an investigation, items including Zhu's toothbrush and mug were stolen from her dorm.

Bei told the Nanfang Daily that he revealed the guidelines to appeal to the police to re-examine the case and to raise money for Zhu's family by bringing the case back to public attention.
