The personal information of Zhu Ling is as follows:
Zhu Ling (November 24, 1973 - December 22, 2023), a native of Beijing, was admitted to Tsinghua University in 1992. In 1994, Zhu Ling developed symptoms of thallium poisoning such as general paralysis and damage to his brain nerves, which caused lifelong damage. Zhu Ling's roommate Sun was a major suspect, and the police also identified the murderer as "around" Zhu Ling, but in the end the case was dropped. In August 1998, the public security organs lifted the suspicion against Sun and lifted the previous restrictions on her traveling abroad.
There is little evidence in Zhu Ling’s case except for thallium poisoning. Even with regard to thallium poisoning, there are still many details that have not been clarified. The specific time and method of Zhu Ling's poisoning are unknown. On April 16, 2013, with the conclusion of the Fudan poisoning case, calls for a thorough investigation of the Zhu Ling case also emerged again. On May 8, the Beijing Municipal Public Security Bureau responded via its official Weibo, stating that it could not be investigated due to the loss of evidence and that there was no interference in the process, calling on the public to view the case rationally.
On November 24, 2023, Zhu Ling celebrated his 50th birthday in his hospital bed. After thallium poisoning, Zhu Ling was diagnosed with a brain tumor in 2023 and was in critical condition; at 22:59 on December 22, Zhu Ling passed away in Beijing at the age of 50.
