Profiler 2: Criminal Investigation Brigade

Yan Shuguang said that he used this word only because, a few years ago, a master said that he had a disaster and wanted to avoid it, so he gave him the word to block evil.As a business person, this kind of thing has always been more credible, so he thanked the master and printed this word on his business card.

Because he is a businessman engaged in sales, Yan Shuguang's business card is sent out as if he does not want money, so it is not surprising that people who are not familiar with him see his name.

Therefore, this so-called "Zhuang Yannian", knowing Yan Shuguang's name, does not mean that he has a very good friendship with Yan Shuguang and is very familiar with him.

In this way, although "Jingxiang" is a clue, it is not easy to investigate further.

Jiao Yang decided to start checking the report letter itself.

The wording has already been said, and there is something archaic.The handwriting is very scribbled. However, to Jiao Yang, who was pressured by his parents to practice brush calligraphy for many years, it looks like it was written by someone with calligraphy skills, and it can even be called cursive script.

The envelope is an ordinary khaki kraft paper envelope specially used for mailing. The circulation may not exceed hundreds of millions, so it is meaningless to trace it.

However, the last letter paper caught Jiao Yang's attention.Although it is said to be letter paper, it is not the kind of transparent paper with red grids.Thick and soft, with some twill.

It's not like ordinary industrial paper, so what kind of paper is it?

The handwriting seems to have been practiced, so this letter paper, is it rice paper? !

The task force invited several paper experts to help identify them, and the experts all agreed that these papers just look similar to rice paper, but they should not be.The craftsmanship of this batch of paper seems to be a bit old, and it seems that it is not very different from the current paper production process. It is more like bamboo pulp soil paper for paper-cutting in some places.

Jiao Yang asked a few experts to help them find out what kind of paper this is.

Now that the suspicion of Yan Shuguang has been gradually ruled out, the attention of the task force has been shifted to the informant.

After reconvening the meeting to discuss, Jiao Yang asked: "Now that Yan Shuguang's suspicion has been ruled out, let's assume that the person who sent the letter is the murderer. Then his purpose should be to divert our attention from the investigation. Why did he risk exposure?" the danger of doing so?"

Lu Yuanli said: "Because he felt threatened, he did not hesitate to take the risk of exposure and sent a letter of accusation to blame others. He should have been investigated by the police, or he should be infinitely close to the person under investigation."

When Lu Yuanli said this, everyone present immediately became excited, because it meant that the investigation by the task force had involved the murderer.

They reorganized all the investigations since these days.There were actually only three suspects who were the focus of the investigation, namely Wang Ning, Jiang Weishen and Yan Shuguang who had some emotional entanglements with the deceased.

They were not regarded as suspects, but it was Qiao Beisha's three close friends and her mother, Qiao Yazhen, who had been in contact with her many times.

After discussing, everyone believed that although the three men were all investigated and ruled out as suspects, they were divided into two situations.

Both Wang Ning and Jiang Weishen are aware of this point. It is in their interest for the police to continue to investigate the case, and there is no need to divert the police's attention.As for Yan Shuguang, it is even more impossible for him to report himself properly, so these three people can be ruled out.

From this point of view, it was Zhao Lingling, Li Xiao, Liu Mei, and Qiao Yazhen who had not been suspected by the special case team before.

However, none of the three girlfriends seemed to know that Qiao Beisha had Yan Shuguang as a friend.And because Qiao Yazhen paid off the debt once for Qiao Beisha, she naturally knew about her daughter's relationship with Yan Shuguang, and she might also know from Yan Shuguang's business card that Qiao Beisha brought back that the owner of the jewelry store also had the word "Jingxiang" .

But, first, Tiger Poison does not eat children. Even if Qiao Beisha is very incompetent, with Qiao Yazhen's financial resources, it is far from being unable to afford Qiao Beisha's expenses. There is no reason at all to kill her only one. daughter.Second, on the night of the incident, Qiao Yazhen had been busy in the western restaurant until very late, and she didn't go out until 11 o'clock in the evening. workers, many employees of the western restaurant, can confirm.Qiao Yazhen herself had no time to commit crimes.

These two are also the reasons why no one in the task force has ever suspected her.

However, the reason is reasonable, and the investigation still needs to be investigated.What's more, Jiao Yang thought of such a point.Qiao Yazhen married earlier and has been single since the divorce. She is only 46 or seven years old this year, she still has charm and financial resources.Who knows if she has some emotional entanglements outside, and Qiao Beisha wants to prevent her mother from remarrying, so that other men have murdered Qiao Beisha in order to marry Qiao Yazhen or plot her property?

Jiao Yang arranged for the police to investigate Qiao Yazhen.At this time, Zhou Ying received a call from the Federation of Returned Overseas Chinese, saying that Qiao Yazhen was going to bury her daughter in the near future, and she hoped that the task force would return the things they had taken away to her.

After the three daggers were identified by the technical investigation, they were not found to be involved in the case and have been sent back to the task force.

After hearing Zhou Ying explain the reason, Jiao Yang said that after the photo was taken and archived, return the three daggers to Qiao Yazhen.

Hou Xiyong said: "Boss, the fact that the remnants cannot be identified does not mean that the three knives must not be murder weapons. They may have been treated technically! Besides, we are going to investigate Qiao Yazhen now. If she, or The person she was related to was really involved in the case, and the murder weapon was one of these three daggers, and after she took it back, she destroyed the murder weapon, wouldn't she be dead without evidence?!"

"It's because of the investigation that I have to return the things to her! Otherwise, if she is really involved in the case, she is deliberately tempting us. If she has already begun to suspect her, wouldn't it be a surprise?"

Jiao Yang said with a smile: "Although it is reasonable to ask for the daughter's things to be buried with her after returning, it is also human nature. But now they are all cremated, such a big cemetery, and Qiao Beisha's collection is so big. Many, can they all be buried together? It’s actually quite strange and suspicious.”

Hou Xiyong laughed and said, "Boss, the thief is still your thief!"

In order to observe Qiao Yazhen's reaction, Jiao Yang personally took Hou Xiyong to return the three daggers. Considering that Qiao Yazhen was a woman, Zhou Ying followed.The three of them arrived at the western restaurant, found Qiao Yazhen at the front desk, returned the dagger to her, and asked her to sign for acceptance after confirming that it was correct.

In order to find the person who wrote the report letter, recently, Jiao Yang has suffered from an occupational disease. No matter where he goes, whenever he sees a piece of paper, he has to touch it with his hands, and when he sees good handwriting, he has to take it for a closer look. look.

While Qiao Yazhen was looking for a pen and paper to write the receipt, Jiao Yang casually touched the books on the front desk while looking at them. When he touched one of them, he stopped his hand suddenly, his heart pounding.

This is a work log. Jiao Yang picked it up and opened it, and felt that the words on it seemed familiar.He immediately pretended to ask the cashier casually, "Isn't there paper here? Whose book is this? Why did you bind it yourself?"

The cashier was also happy to chat with this handsome young police officer, and said with a smile: "This is our manager Wei's notebook. He likes to use this kind of soft paper, saying it is better for writing."

Wei Dalun!Jiao Yang immediately tore off a blank page from the notebook and asked Qiao Yazhen to use this paper to write the receipt.

Qiao Yazhen didn't understand, so although she felt that it was not very formal for Jiao Yang to tear up a piece of torn paper and write a receipt like this, but since the police officer said so, she took it and wrote the receipt without thinking too much, and followed Jiao Yang's instructions. According to the requirements of the signature, I pressed my fingerprints at the signing place.

Jiao Yang took it over and looked at it, pretending to take pictures on the spot for proof, so he took the notebook as a pad, casually opened a page where there was a lot of handwriting, and took several photos with his mobile phone.

After Jiao Yang went back, he immediately found the two letters of accusation in the file bag, and compared the handwriting on the letter paper with the words in the photo.But, disappointingly, not quite.

However, when he touched the letter paper carefully, he found that the feel of the two papers was almost exactly the same.

Jiao Yang was afraid that it was his own illusion, so he also called Hou Xiyong and Zhou Ying and they all touched it in turn, and everyone felt that it was very similar.

But the handwriting is different, could it be that someone else stole Wei Dalun's paper, and this person is also in the western restaurant... Wait a minute!Jiao Yang looked at Wei Dalun's handwriting for a while. From his point of view, it was very skillful, as if he had practiced calligraphy for many years.

The handwriting on the report letter is also, is it just a coincidence, or... Could this person write with his left hand? !

An idea flashed in Jiao Yang's mind, and he immediately copied out the photo he took, and sent it to the technical detective together with the receipt paper.

After the professional technical appraisal of several paper experts, this paper is the same as the paper used for the anonymous letter in terms of texture, pulp, texture, and production process.Moreover, this piece of paper is not only the same as the paper used in the report letter, it is even cut out with one knife, and it belongs to within 100 sheets.

At the same time, the police learned through a secret visit to the clerk of the western restaurant that Wei Dalun really loves calligraphy, he can write with both hands, and he knows a variety of fonts.The clues of the case point to Wei Dalun.

Experts from the Municipal Bureau judged by the universal principle of handwriting identification: no matter whether a person writes with his left hand or his right hand, his writing habits will basically not change.And the writing speed can't change some handwriting characteristics.

The results of the appraisal finally concluded that the handwriting on the report letter and the handwriting on the photo should belong to the same person, and Wei Dalun is suspected of committing a major crime!

Although it was already late at night, the task force set off immediately and went straight to Qiao's Western Restaurant.The western restaurant is still open, but the female boss Qiao Yazhen and Wei Dalun are not there.
