Dai Xu did what he said, and the first thing he did after returning to the Public Security Bureau was to call the sub-bureau in charge of Wu Xuehai's case, contact the sub-bureau colleague who was mainly responsible for this matter, and tell the other party about the situation he had mastered on his side. The other party got Dai Xu's prompt, and also expressed deep sympathy, because after Wu Xuehai was arrested, he seemed to be more nervous and flustered than the few gangsters and hooligans who were the heaviest. But the more he emphasized it, the more suspicious it became, after all, the police who handled their case were not rookies, they were still very experienced, and they had already doubted it, and when they heard Dai Xu say this, they were more sure of their feelings and judgments, so they thanked Dai Xu and said that they would investigate carefully.

After communicating this matter, in the next follow-up part, Dai Xu doesn't plan to ask too much, if there is any information feedback, they can listen to the results, after all, they are really responsible for the case of Ke Xiaowen's murder, as long as there is no direct and clear evidence pointing to Wu Xuehai to prove that he is related to Ke Xiaowen's death, then Wu Xuehai does anything else that violates the law, there will be other police to investigate and deal with it, It wasn't Dai Xu's turn and Fang Yuan to waste their energy and time on this matter.

In the morning, Fang Yuan received a message. said that someone found something that was suspected to be Ke Xiaowen's personal belongings, and it didn't take long for the thing to be sent over. It's a schoolbag of a certain sports brand, it looks half-new, it's still wet, it's covered with water, and you can smell a peculiar smell of still water when you get closer, it's not easy to ask, Dai Xu and Fang Yuan opened the schoolbag. I saw that there were several review textbooks for the third grade of high school, including textbooks and workbooks. These things are soaked wet, and there is even a faint smell.

Dai Xu rummaged through the top of the schoolbag, where there was a place for hanging signs, there was nothing there, and there was no way to find the personal information of the owner of the schoolbag. I asked for a while to find out. The reason why I suspect that this schoolbag may belong to Ke Xiaowen is because there is a red seal on a textbook in the schoolbag, which is printed with the name of the key high school that Ke Xiaowen attended, so combined with the recent disappearance of Ke Xiaowen that is being investigated, I immediately linked these two things together, thinking that this schoolbag is likely to belong to Ke Xiaowen.

So since there is no name on the bag, I have to look for it from the book. Dai Xu and Fang Yuan carefully took out the several large books in the schoolbag, which were probably together with the schoolbag. I've been soaking in water for a while, the schoolbag is okay, after all, it's fabric, in addition to being wet and with a peculiar smell, there is no other problem, but the schoolbag is not waterproof, the book inside is not very good, the paper has been soaked for a long time, it has long been wet and transparent, in addition to the book cover can barely stand up, the other papers have basically been soaked very soft and fragile, it is very difficult to open the pages, many pieces of paper are soaked together, and they don't dare to separate, I'm afraid it's going to tear it all at once. Even rough unfolding of the book requires great care, because a slightly heavier movement may knock off the book cover.

Fang Yuan and Dai Xu flipped through it very carefully, and found that the name was not written on the second cover inside the book cover, and the side of the page was not written, so those textbooks were not mentioned, and in the basic exercise book, I don't know if the original owner was more accustomed to using pencils to do exercises, after these exercise books were soaked in water for a while, only some very shallow handwriting could be seen on the pages inside, not to mention providing the owner's personal information, even if you want to see clearly what the handwriting on it is and what is written, it is very difficult, almost impossible.

However, although there was no owner's name on the book or in the exercise book, Fang Yuan still saw a clue, she found that there were two books in them, which were exactly the same as the books stored in Ke Xiaowen's locker, and it was estimated that they were all purchased by the school or distributed to students in a unified manner, so that since Ke Xiaowen's two books, Fang Yuan remembered very clearly, they were in the locker in Ke Xiaowen's own bedroom, then this schoolbag should not be Ke Xiaowen's.

To be on the safe side, Dai Xu called the school, hoping that they could find a teacher to go to Ke Xiaowen's dormitory, open his locker, and see if the two books were still there.

After all, it was the students in their school's mobile key class who had an accident, and the school still paid more attention to it, so he agreed without saying a word, and notified the dormitory manager to go to the dormitory where Ke Xiaowen lived before his death, and checked the items in Ke Xiaowen's locker, about twenty minutes later, the school called and fed back to Dai Xu The result was that Ke Xiaowen's locker did have those two books in it, and Fang Yuan was not mistaken.

Then it is even more certain that this schoolbag is not Ke Xiaowen's. But is it Ke Xiaowen's, and who will it be? Judging from the book materials, it naturally belongs to a senior high school student, and this student should also be from that key high school, because when he called the school to inquire and ask the teacher to help check Ke Xiaowen's locker, Dai Xu also asked by the way, the origin of those books and textbooks, and learned that one of the books and a set of exercise books is the secret weapon of this high school. After the college entrance examination, I don't care much about it, because this kind of "secret weapon" with a strong timeliness is worthless once it expires.

Judging in this way, this schoolbag should belong to another student from that key high school like Ke Xiaowen, but then Dai Xu raised another question.

"You say, how many students in this world who have just entered the third year of high school and are still sprinting and struggling will choose to throw away their school bags? I've seen it because it's too stressful. So irritable, or very irritable because of a failed exam. Then I impulsively tore the book and the exercise book, but I haven't seen it thrown away along with the schoolbag. Dai Xu said thoughtfully to Fang Yuan, "And this schoolbag and books are so wet, and there is a smell of stinky water, it is obvious that they have been thrown into some wild still water, throw the schoolbag and throw the schoolbag, and there are so many places not to throw it." Why do you have to throw it into the water? ”

Fang Yuan leaned his nose closer to the books again, and sniffed them carefully, in the peculiar smell that had been soaked for a long time. There is also a little bit of fishy smell, this fishy smell is different from fishy, different from bloody, but with a bit of earthy. She thought for a moment. I tried to speculate: "Smelling this smell, it feels like one kind of lake where the water doesn't flow much, and throwing my bag in that kind of place, I can think of only one purpose, and that is to make people unable to find it." ”

"yes, it's not very easy to salvage if it's thrown to the bottom of the lake, if it's just a prank. That joke was a bit big. Dai Xu nodded and picked up the phone. The person who helped Fang just deliver the schoolbag to them called and asked where the schoolbag was found.

Before the call was over, a colleague from the criminal technique over there also came over and brought a handwriting analysis of the scratches on Duan Feiyu's runaway letter. Fang Yuan thanked him and took it, the other party didn't stay longer when he saw that they were still busy, he left in a hurry, Fang Yuan looked at the conclusion on the report, his eyes lit up obviously.

When Dai Xu asked clearly where the schoolbag was salvaged and hung up the phone, she hurriedly handed the report to Dai Xu like a treasure, and said to him: "Look, this is the conclusion report just sent, the runaway letter that Duan Feiyu left to his parents, the traces on it are really herself, and the content after being identified and restored according to those handwritings, you will definitely find it particularly interesting after reading it." ”

Dai Xu raised his eyebrows, took the conclusion report from Fang Yuan's hand, and quickly browsed the content on it, this report said that the traces on the runaway letter were indeed handwriting, and after careful identification and restoration, as well as the scrutiny of the content, they believed that the words written on those traces were exactly the same as the content on the runaway letter, except for a slight difference in individual words, there were basically no major changes.

In addition, it is worth mentioning that after some identification and identification of the handwriting, the staff in charge of the document inspection believes that although the handwriting on the runaway letter has a high degree of similarity with the handwriting on Duan Feiyu's language scroll, from the perspective of the strength and writing habits of some comparisons, it should not be from the same person's handwriting, but someone is very careful and careful, and the handwriting of Duan Feiyu can almost be imitated as fake.

"Don't say it, this thing is really interesting," Dai Xu smiled after reading the contents of the report, "The results of the handwriting identification and the handwriting marks on the runaway letter, these two conclusions can be said to complement each other, the actual writing content of the scratch marks illustrates the conclusion of the handwriting identification, and the conclusion of the handwriting identification also gives a very reasonable explanation for those scratch marks." Whoever writes a letter of running away from home by himself, the content is not particularly complicated, the form is even simpler, just leaving the book and running away, a very impulsive behavior, for Duan Feiyu, maybe he is still familiar with it, so where can he be nervous? A child who has been able to run away from home with the family's money silently since he was a child, do you think he will not only change his mind this time and leave a book to run away, but also need to be nervous to the point of repeatedly typing drafts when writing a letter to run away from home? This is obviously unreasonable, and there is only one reasonable explanation for the need for a draft-"

He dragged out a long note, and did not say the conclusion directly, but motioned for Fang Yuan to finish speaking for himself, Fang Yuan had been following the train since he heard him say this, and now when he heard him say this, he naturally immediately understood it, and said: "Unless someone wants to imitate Duan Feiyu's handwriting and create the illusion that Duan Feiyu has run away from home, and they are afraid that the imitation is not similar enough, so they need to practice repeatedly, or try to write a few words first, and repeatedly adjust to the point that they feel that the feeling of writing is the most realistic, It's really the official start of writing. ”

"Let's go," Fang Yuan said the same conclusion as his own thoughts, Dai Xu nodded with satisfaction, then stood up and stretched, "Although it's not warm today, it's still a beautiful day, let's go out for a walk, go to the park, relax and breathe fresh air!" ”

"You want to go to the spot where the bag was salvaged, right?" Of course, Fang Yuan knew that Dai Xu didn't look at what he said lightly, as if he was going out to fish in a hurry, in fact, he was going to get down to business, the stinky water and earthy smell on the schoolbag meant that it was fished out of the deep water, but the schoolbag itself was not stained with too much mud, which showed that the place where the schoolbag was thrown was just a pool of still water with some unpleasant smell, and the surrounding environment was not necessarily bad, so the surrounding environment was not bad, The most likely place where there is not much dirt in the water but is a little still smelly is the park.

"It's true that I'm going to see the place where the schoolbag is salvaged, but that place is in the park, and the two of us walked through the park, which in itself can be regarded as visiting the park and getting some fresh air, right?" Dai Xu said with a smile, "People, the most important thing is to combine work and rest, have fun in hardship, and relax your nerves when you see stitches." ”

The two of them set off immediately, they are going to a park in city A, this park is located in the center of the city, it is the most noisy and quiet place in the whole city, it is quite well-known in city A, there are not too many landscapes or other amusement facilities in the park, a park was planned here, the original intention is also to give residents living near the city center a green environment that can breathe fresh air and move their bodies, and by the way, it is equivalent to decorating some greenery in the cement forest in the urban area. Therefore, although the park is not small, it contains only a large area of woods and meadows, and a very large artificial lake.

The most famous of the whole park is probably the huge artificial lake, after all, a park only has trees, only grass, and it seems a little monotonous, and the pedal boat on the artificial lake can attract many young couples who come here to stroll and date in summer.

And Fang Yuan and Dai Xu's goal this time is the artificial lake that this couple prefers. (To be continued......)
