It is said that justice may be late, but it will never be absent, but unfortunately the victim can't see it, Zhu Ling, who has experienced thallium poisoning twice, can live until now It is a miracle, I hope that heaven will not be sick and go all the way.
A review of the case:
In November 1994, Zhu Ling, who was studying at Tsinghua University, suddenly fell ill and suffered pain in his limbs, and was later diagnosed with thallium poisoning in 1995, and a case was filed for investigation in May of that year. During the investigation, there was a burglary in the dormitory, only the victim's daily necessities were lost, and the theft was not investigated clearly.
There are more and more detailed articles on the Internet, interested friends can go to find and see, there are still a lot of doubts in this case.
What I want to focus on is that no matter who this case is, what you want to cover up, no matter who you are, and what you want to escape, I implore the public security organs to spare no effort to investigate this kind of case that has a great impact on society!
I also believe that many people feel the same way as I am, and the abuser must get the punishment he deserves, no matter how long it has been!If there are difficulties in the local area, then apply for an off-site survey.
I think the five suggestions given by Detective Li Changyu for the investigation of this kind of cold case are very pertinent.
First, it is the poison that is being traced**. It is possible to investigate whether any professor used this poison in his experiments, and who among the professor's students had access to and intersected with the victim. Even if the management was disorderly back then, all the people who handled it could investigate it, and there would be clues.
Second, the specific time of poisoning can be determined according to the content of poisoning in the blood, and see who was with the victim during the time of poisoning, which Li Changyu called "artificial intelligence". He said that "in this kind of poisoning case, only people who are close to her have a chance."
This may not be easy to achieve now, but the cases of that year should be detailed with the investigation data of **.
Third, trace the route of poisoning. You can look for clues in the victim's personal belongings.
This still has to start with a theft, which may already be difficult.
Fourth, investigate who would have the motive for poisoning. "When college students are poisoned, we have to see if they are jealous of others and have conflicts with anyone. "Whether the victim or suspect has a diary or other records.
This should be useful.
Fifth, it can detect polygraphs on suspects.
I think that all the students related to Zhu Ling should check this point, and they should find out.
In summary, in fact, no matter how you look at it, this case is not so difficult to investigate, why did it become a cold case, so many years of chaos in school management (thallium, and dormitory theft), * The handling is not rigorous and detailed enough, it should not be able to get rid of the relationship, as for the outside world speculation that someone intervened, it is hard for us to say.
But for a case with such a wide impact, no matter who has much influence, it should not be a factor hindering the handling of the case
