It is indeed regrettable that Zhu Ling's case remains unresolved, and nearly half a year has passed between the time Zhu Ling showed symptoms of poisoning and the time when the public security organs officially took over the case. The passage of this time has undoubtedly brought great difficulties to the investigation of the case. Especially in the absence of monitoring facilities and the loss of criminal traces and physical evidence, the investigation work is even more difficult. However, this does not mean that the case cannot be solved, nor does it mean that a murder cannot be solved in a place where there is no monitoring facility.
The success of a criminal investigation does not depend solely on the availability of surveillance facilities. Although surveillance facilities play a vital role in modern criminal investigation, the investigation work also includes many aspects such as scene investigation, witness questioning, and physical evidence identification. In the absence of surveillance facilities, there is a need to rely more on other means to gather evidence.
Criminals are indeed likely to avoid places with surveillance facilities when choosing where to commit crimes. But this does not mean that they will be able to go completely unpunished in places where there are no surveillance facilities. **Suspects can be tracked and located by other means, such as analysis through communication records, whereabouts, etc. With the development of science and technology, more advanced technical means can also be used to assist in investigation, such as big data analysis, face recognition, etc.
For a complex case like the Zhu Ling case, the investigation work also needs to take into account various possible factors. Are there more than one suspect?Is there a complex motive and background for the crime?All of these factors may have an impact on the investigation of a case.
Criminal investigation is a long-term and arduous task. Even though 30 years have passed since the case, ** still has the obligation and responsibility to continue investigating the case until the real culprit is found.
The suspense in Zhu's case cannot simply be attributed to factors such as the lack of surveillance facilities or the passage of time. Criminal investigation is a complex and arduous task that requires a great deal of effort and patience. It should also be recognized that the development of science and technology has brought new possibilities and challenges to criminal investigations. In the face of similar complex cases, I heard that it is necessary to remain calm and rational and give the necessary support and understanding, and also look forward to using more advanced technical means and investigation concepts to solve similar cases.
