Chapter 1151 Discovery of the current investigation
There were not a few cases like this in the past, but with the development of criminal investigation technology in recent years, the application of many new technologies has brought about a turn for the better in some previous backlogged cases.
In the past two years, the Criminal Police Brigade of the High-tech Zone has been involved in many cases that were not solved in the past. Pointing evidence at the crime scene was found to prove that the other party was the murderer, and the person was immediately arrested. .
Of course, with the improvement of the rule of law, this kind of thing has rarely happened in recent years. Even in the process of interrogation, fatigue interrogation methods are generally rarely used.
Of course, the main reason is that with the advancement of science and technology, criminal investigation techniques are also constantly improving.
Decades ago, fingerprint verification was not that common, but now fingerprints, blood stains, DNA footprints, etc., have become relatively common criminal investigation methods.
At the same time, technical police types such as detective detectives are now receiving more and more attention.
And with the progress of the times, there are various forms of crime. Some high-tech crimes and high-IQ crimes must use some high-IQ solutions to solve the cases.
Three months ago, the ministry reported another crime. The report of this crime was not allowed to be communicated externally as an internal report, and it was only communicated to a certain level.
As the captain of the Criminal Police Brigade of the High-tech Zone, Wang Zhaokai is the lowest level to know about this case.
This case appears to be an accidental death, but in fact it is a deliberate murder.
The deceased was killed by a falling fan at home.
When the police investigated at that time, they were actually very careful. Because the fan has a relatively heavy weight, the cable hanging on it will eventually break due to long-term stress. Therefore, if the fan falls, the people below will be killed. Smashed to death.
It was originally an ordinary accidental death case, but there was a new detective.
Follow the master to study on site. When he checked the rope, he found that the date on it was different from the production date of the fan.
The fan was manufactured 10 years ago, but the cable was manufactured a year ago.
The fan left the factory 10 years ago and was installed in this house, but the cable is actually new and was only replaced a year ago.
The quality of this cable is so poor that it broke within a year.
In fact, judging from the broken gap, there is indeed no trace of man-made damage to the cable. It broke due to excessive force.
However, this still aroused the suspicion of the police, and they were discovered after a series of careful investigations. Behind this so-called accidental death case turned out to be a deliberate murder.
The man who died was the man of the family, and the one who killed him was his wife.
This wife wanted to keep the family property for herself because she had an affair, and then she planned to kill her husband.
The wife came up with the idea of this fan because her husband has a habit of drinking tea on the sofa under the fan every day.
So his wife replaced the fan cable, and the quality of the new cable was not bad, but he used gravity to pull it apart beforehand, and it was already about to break. .
At this time, because there were no traces of man-made damage to the cable, only signs of breakage caused by long-term stress, the police would not suspect it at all.
What exposed this wife was that the cable he used had a production date on it that was only produced a year ago.
In fact, if the wife had tampered with the original cable, she would have a greater chance of success. Of course, the police checked the original cable and found that it was a chain, so there was no possibility of tampering with it. Not big.
This may be why the other party chose to replace the cable, leaving a loophole. So this kind of case not only requires carefulness, but the wife's IQ is actually very high. He did not directly destroy the Range Rover, but replaced it with a new one.
As for the cable she exchanged, she also used the method of using gravity to tear it apart, forming a shape that was almost broken but not broken.
Therefore, no matter what case we handle, whether it is a big case or a small case, evidence is very important. Once you have solid evidence, you can do other things.
Be it Wang Zhaokai or Lu Chuan, they have handled many cases, but in fact they all involved zero confession. The other party said nothing, but the evidence was dead.
As long as there is evidence and irrefutable evidence, the entire evidence chain is closed-loop, and the logic makes sense, then it doesn't matter even if the criminal suspect says nothing or refuses to admit it.
But if there is no evidence and only confession, then there is a problem with this case.
After Lu Chuan arranged for Wang Zhaokai to stare at Zhang Chao, he left the scene.
Just now when he was in the car, news came from Nanzhou.
The case where Zhang Chao and Zhang Quan exchanged identities requires cooperation in the interrogation after Zhang Chao is captured.
To be honest, according to Lu Chuan’s understanding, the case in Nanzhou was actually more difficult to solve, because there was no evidence directly pointing to Zhang Chao at the robbery scene, so Zhang Quan was arrested. .
Lu Chuan also learned about the case over there at that time. The reason why they were able to identify the suspect there was because Zhang Chao was caught on surveillance camera robbing him.
But because Zhang Chao and Zhang Quan looked exactly the same, Zhang Chao took advantage of him and let Zhang Quan go to jail for him.
But even if this is the case, bringing Zhang Chao back can only be based on the confessions of the two to determine who committed the crime.
But then again, if the facts of Zhang Chao's crime here are finalized, there is no need to go back, because the crime committed here is robbery and murder, which is enough to constitute the death penalty.
Under normal circumstances, even if it is intentional homicide, the possibility of direct execution is not particularly high. Under normal circumstances, the death penalty is suspended for two years.
But if you commit robbery and murder, it will basically be a direct death penalty.
Among various types of crimes, robbery has always been punished relatively severely, especially home invasion and robbery.
Home invasions, multiple robberies, bank robberies, public robberies, etc. are all subject to severe penalties.
If this is the case, then the case where Zhang Chao directly executed the death penalty would also be the death penalty when superimposed on this case.
The transfer took place in the evening.
All the work was progressing in an orderly manner. When Lu Chuan received the call from Yang Lin, he didn't know that there must be something discovered there.
Or maybe they just found some general clues, but Yang Lin gave Lu Chuan a big surprise.
Yang Lin called Lu Chuan and the trace evidence analysis had results!
Sure enough, the trace evidence analysis that Lu Chuan had high hopes for has made a major discovery!
