Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 1151 Discovery of the current survey

There were quite a few cases of this kind in the past, but with the development of criminal investigation technology in recent years, the application of many new technologies has brought turning points to some of the old cases.

In the past two years, the High-tech Zone Criminal Police Brigade alone has been able to solve many cases that were previously unsolved. They found evidence pointing to the murderer at the crime scene, proved that the murderer was the one who was arrested directly.

Of course, with the improvement of the rule of law, such incidents have rarely occurred in recent years. Even during the interrogation process, fatigue interrogation methods are rarely used.

Of course, the main reason is that with the advancement of science and technology, criminal investigation techniques are constantly being improved.

Decades ago, fingerprint verification was not so common, but now fingerprints, bloodstains, DNA footprints, etc. have become more common criminal investigation methods.

At the same time, technical police types such as on-site investigation criminal police are now receiving more and more attention.

Moreover, with the progress of the times, the forms of crime have become more diverse. 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. This crime report was an internal one and was not allowed to be disclosed outside. Moreover, it was only circulated to a certain level.

As the captain of the High-tech Zone Criminal Police Brigade, Wang Zhaokai is the lowest-level official who can know about this case.

On the surface, this case was an accidental death, but in fact it was a premeditated murder.

The deceased was killed by a falling fan at home.

When the police were investigating, they were actually very careful. The fan was very heavy, so the cable hanging on it was under long-term stress and eventually broke. The fan fell and happened to kill the person below.

It was originally an ordinary accidental death case, but there was a new detective.

When he followed the master to learn on site, he found that the date on the rope 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 was manufactured 10 years ago and installed in this house, but the cable is new and was replaced just a year ago.

The quality of this cable is so poor that it broke in just one year.

In fact, judging from the broken gap in the cable, there is indeed no sign of human damage. It broke because of excessive force.

However, this still aroused the suspicion of the police, and after a series of careful investigations, they found that this so-called accidental death was actually a deliberate murder.

The man of the house died, and it was his wife who did it.

Because the wife had an affair, she wanted to take all the family property for herself, and then she planned to kill her husband.

The wife set her sights on the fan because her husband had a habit of drinking tea on the sofa under the fan every day.

So his wife replaced the fan's cable. The quality of the new cable was not bad, but he had used gravity to pull it apart in advance, and it was already on the verge of breaking.

At this time, the police had no suspicion at all because there were no signs of human damage to the cable, only signs of breakage due to long-term stress.

What exposed the wife was that the cable she was using had a production date that showed it was only produced a year ago.

In fact, if the wife had tampered with the original cable, the chances of success might have been greater. Of course, the police checked the original cable and found that it was a chain, so the possibility of tampering with it was not high.

This may also be the reason why the other party chose to replace the cable, thus leaving a loophole. So this kind of case not only requires carefulness, but also the wife's IQ is actually very high. He did not directly destroy the Range Rover, but replaced it with a Range Rover.

As for the cable she got, she used gravity to tear it apart, creating a shape that was almost broken.

So no matter what case you are handling, no matter whether it is a big case or a small case, evidence is very important. Only after you have solid evidence can you do other things.

Whether it is Wang Zhaokai or Lu Chuan, they have handled many cases in which there was actually no confession. The other party would say nothing, but the evidence was dead.

As long as there is evidence, solid evidence, the entire chain of evidence is closed and the logic is tenable, then it doesn't matter even if the suspect says nothing and refuses to admit it.

But if there is no evidence but only confessions, then there is something wrong with the case.

After Lu Chuan arranged for Wang Zhaokai to keep an eye on Zhang Chao, he left the scene.

Just when he was in the car, news came from Nanzhou.

In the case where Zhang Chao and Zhang Quan exchanged identities, we still need to cooperate in the interrogation after we catch Zhang Chao.

To be honest, according to Lu Chuan's understanding, the case in Nanzhou was actually more difficult to handle, because no evidence that could directly point to Zhang Chao was found at the robbery scene, so Zhang Quan was arrested.

Lu Chuan also learned about the case at that time. The reason they were able to identify the suspect was because the surveillance camera captured Zhang Chao robbing.

However, because Zhang Chao and Zhang Quan looked exactly the same, Zhang Chao took advantage of the situation and had Zhang Quan go to jail for him.

But even in this case, if we bring Zhang Chao back, we can only determine who committed the crime based on the confessions of the two people.

But then again, if Zhang Chao's crime here is confirmed, then he doesn't have to go back, because he is guilty of burglary and murder, which is enough to constitute the death penalty.

Generally speaking, the possibility of direct execution of the death penalty even for intentional homicide is not particularly high. In general, the death penalty is suspended for two years.

But if the home robbery is combined with murder, it is basically a direct death penalty.

Among all types of criminal acts, robbery has always been sentenced to heavier penalties, especially home robbery, which is punished severely.

Home robbery, multiple robberies, bank robbery, robbery in public places, etc. are all subject to severe punishment.

In this case, the case in which Zhang Chao was directly executed would also be a death sentence when added to this case.

The turning point occurred in the evening.

All the work was progressing in an orderly manner. When Lu Chuan received the call from Yang Lin, he actually didn't know that there must have been some discovery over there.

Or it could be said that he just found some general clues, but Yang Lin gave Lu Chuan a big surprise.

Yang Lin called Lu Chuan, and the results of the trace evidence analysis were out!

As expected, the trace evidence analysis that Lu Chuan had high hopes for had made a major discovery!
