This is a way of preserving data. Although there are now computer archives, original paper materials are still indispensable.

"1987?" When Hu Pingtao looked at the time on the card, he subconsciously said "yo ho" and said in surprise: "This time is long enough!"

Zhang Yixuan was sitting opposite, busy writing something in his notebook, and asked without raising his head: "Is this the man who killed his wife Xie Anguo?"

Hearing this, Hu Pingtao moved his eyes downwards and just saw the words "Xie Anguo" written in carbon ink at the bottom of the card.

"Yes, it's Xie Anguo." He raised his head and asked Zhang Yixuan: "Why, did this man kill his wife?"

Gu Dewei happened to walk to the water dispenser with an empty cup. He heard the conversation between the two and explained to Hu Pingtao with a smile: "We broke a murder case some time ago. We just handed over the materials the day before yesterday. We have nothing to do for the time being.

, just settle old scores as usual."

In the criminal investigation team, "recovering old scores" is a special term. Hu Pingtao has worked with everyone before and knows that this is to dig out old accumulations and look for new clues.

Not every crime can be solved in a short period of time. The relationship between criminals and the police is a battle of wits and courage. Whether murder, robbery, fraud or any other form of crime, a lot of manpower and material resources are required to carry out the crime.

Inspection and detection.

There is a detection rate, but one thing is certain - not all cases can be solved, and there is no 100% detection rate in any region.

There are many reasons why the case cannot be solved, and it is impossible for the police to focus all their resources on a certain difficult case. On the one hand, it is because of the lack of clues, and on the other hand, new cases are emerging one after another. Compared with those cases that cannot be solved in a short period of time,

For any difficult problems, we must first use the limited resources at hand and solve the easy ones first.

Some old cases were due to insufficient comprehensive investigation conditions at that time.

For example, some murder scenes were destroyed and became chaotic. With the technological means at the time, it was impossible to find accurate evidence.

Ten years ago, it was impossible to extract fingerprints from eucalyptus sites under limited conditions.

Ten years later, through special means, clues can be found from the on-site evidence in Mohu.

DNA, face recognition, biological gene comparison, residual genetics... many things that were once "impossible" have now become "possible".

Many old cases have been cracked in recent years, and criminals who have been hiding for many years have been caught one by one. This is the result of technological research and development.

Hu Pingtao knew this very well.

He raised his head, looked at Gu Dewei, tapped the file in his hand gently with his knuckles, and asked doubtfully: "Does this mean there are clues to this case?"

He knew Zhang Yixuan's working habits - problems that were easy to solve were usually placed at the top of the file, as were materials that were urgently needed for delivery.

Zhang Yixuan shook his head angrily: "It would be great if there were clues. There are documents on it. If you can clear a certain proportion of accumulated old money within the year, you will get extra points in the year-end evaluation, and there will also be bonuses!"

Hu Pingtao frowned and asked: "Since you can't break the eucalyptus, why did you put this eucalyptus on it?"

Gu Dewei explained beside him: "We got it done yesterday. In fact, we didn't expect any progress in this project. The main reason was that Xie Anguo himself came to the bureau yesterday and said that this project was done wrongly and that we should give him justice.

.”

Hu Pingtao became more and more confused: "Is it wrong? What happened?"

Zhang Yixuan was not in a hurry to explain, he shrugged his shoulders: "The information is in your hands, you can take a look first and then talk!"

Hu Pingtao untied the file.
