[I made a mistake yesterday and sent chapters 8 and 9 together...... Now correct the ......]

If you want to strictly follow Dai Xu's footprints, it is not a particularly easy thing for Fang Yuan, usually Dai Xu's stride, one step can almost be equivalent to Fang Yuan's one and a half steps, just now Dai Xu himself walked over with a big step, the span in the middle of each footprint is even larger, Fang Yuan almost needs to jump forward to make sure that he really steps in Dai Xu's footprints, Fang Yuan just jumped two or three steps, and finally got to the snowdrift of Fang Cai, and then she found that when Dai Xu looked at herself, There seemed to be a little smile in her eyes, which suddenly reminded her of the incident that Fang had just "stood here guarding".

"You just asked me to step on your footprints...... Is it a joke too? She asked tentatively.

Dai Xu hurriedly adjusted his expression, tried his best to show a little strictness, shook his head, and said seriously: "No, before the two of us are sure that there is a discovery, it is not good for colleagues from other departments to come over and accompany the search, but now that we are sure that there is a discovery, of course we have to pay attention to protecting the scene." ”

Fang Yuan nodded hurriedly, and then looked at the snowdrift that Dai Xu had just dug up, the tool in Dai Xu's hand was only a pointed shovel, which was not very convenient, so he didn't dig very deep, but the part he dug up had exposed the soil on the ground, and from the soil, you could clearly see a person's hand, that hand was intact, but it was a little stiff and pale from the frozen, and the arm connected to this hand was different, except for the wrist, which looked relatively normal, and the rest of the part that exposed the ground, In addition to being stained with dirt, none of them are intact, the meat on the arm has obviously been removed with a knife, but it is not clean, some places can see red and white bone traces, and some places are wrapped in meat that has not been cleaned, the color of the meat is dark red, but there is no obvious bloodstain, even if it is dry, with Fang Yuan's theoretical basis and professional knowledge, there is no way to judge whether it was the murderer who let go of a lot of blood before the deceased's blood coagulated when he disposed of the corpse, Or because of the low temperature in winter, the corpse was freeze-dried.

Looking at the intact and stiff hand, as well as the mottled arm connected to the hand, Fang Yuan's scalp was a little faintly numb, as if there were a few little ants crawling around, she was afraid that showing too strong a fear first would make Dai Xu feel that she was not competent enough, so she only stepped back a little, and then took a few breaths and asked Dai Xu: "The arm is exposed, is it that the other parts must be here?" ”

"I don't think it's very likely, when I was digging the soil just now, I found that the soil was still relatively hard, and I felt that it was difficult to reopen the soil that the murderer had moved to the side of the body, and let the murderer dig a deep pit as big as a person to bury people in, not to mention whether the target would be too big, just the body, I'm afraid it is not easy to achieve. Now the more optimistic idea is that half or more of it can be found here, and the rest is definitely in this children's park. Dai Xu looked at Fang Yuan's expression as he tried to keep his composure, took a few more steps, and then motioned for Fang Yuan to follow him.

Eyes left the exposed arm, Fang Yuan's breathing finally became smooth again, and her mind became active again, she looked at Dai Xu with curiosity, and was about to ask, Dai Xu took the first step to see her thoughts, and teased herself before she could speak.

"Do you have a feeling now that I could be the murderer?" He asked.

Fang Yuan didn't expect him to ask himself such a question at all, he didn't hold back for a moment, and laughed.

"If you weren't a policeman, I'd be suspicious of you." She laughed and told the truth, "From the moment I received the report from the scene in the morning, until now, I haven't seen any signs that people can push out that the body may be buried in the children's park, even if there is, the children's park is so big, the area of this forest alone is not small, why can you find the place where the body is buried at once, without any detours?" I don't think even if a police dog comes to find it, it may not be able to guarantee that it will be found directly and accurately so quickly. ”

After finishing speaking, she realized that her wording was very problematic, and quickly changed her words: "No, no, I don't mean to compare you with dogs, you must not be like me......"

"I guess ......" Dai Xu did not express any displeasure because of this sentence, but seemed to be very funny, thought for a while and said, "I don't have a good sense of smell as a dog, but my brain should be a little smarter than a dog." No kidding, in fact, there must be a lucky element in this matter first, and secondly, if you want to solve the case, you must first learn to empathize, if you not only stand on the opposite side of the criminals in the role, but also the way of thinking, then it is not good, knowing yourself and knowing the other party can win all battles, if you want to see through the other party's tricks, you have to bring in his way of thinking. Before we came over, didn't the two of us already talk in the car, do you still have an impression of the content of the conversation? ”

Of course, Fang Yuan remembered that Dai Xu had asked her a lot of questions at that time, and now that he thought about it, it turned out that when he expressed his opinion, Dai Xu had already made such a series of analyses and judgments in his mind.

In the urban area, there is no need to consider the transportation of the corpse to the suburbs and the wild, there are few people in the park in winter, the woods are far away from other facilities in the park, and the soil layer is thick, and it just happened to catch up with the reconstruction construction of the park, only the time period of construction on the site is left, and it will not attract attention. But how do you know there's work going on? Fang Yuan asked.

"Oh, there is a program on the local life channel in City A, which specializes in solving the problem of citizen feedback or something, a few days ago the program also mentioned that many citizens reflected, saying that the children's park was very dirty because of the winter construction and transformation, several gates were open all day, and there were often various trucks in and out, morning exercises, scattered citizens do not like to come, even the people who used to bring children to play are also suspicious of miscellaneous cars, do not like to bring children, many people call to complain about this, The host of the show also asked the audience to try to be patient now in order to have a better place to relax after the spring flowers bloom. Dai Xu raised his eyebrows, "I can watch TV to know about this, and the murderer must be able to do it too." ”

"I really didn't expect that kind of show to be a helpful source of clues to solve the case!" Fang Yuan was young after all, and he was never very interested in that kind of citizen program, and he had the impression that only the old people in the family liked to sit in front of the TV and watch it after dinner or dinner, but he didn't expect Dai Xu to know about it.

"A lot of times, important information is hidden in the right place, and even the street tabloids that specialize in celebrity gossip and scandal can't guarantee what information can be provided." Dai Xu said.

"But I still have one more question, why did you go straight to the birch forest? The rest of the park also has a green area covered with vegetation, and the soil is very thick. Although Fang Yuan learned about Dai Xu's source, the doubts in her heart were not completely solved, from Dai Xu's prompt, it became well-documented to lock the scope to the children's park, but all of a sudden, she found the snowdrift where the body was buried, which was still a bit unbelievable.

"You're right, there are other places where you can dig pits and bury the bones in, but if you think about it, let's drive all the way over, the places you said are relatively close to the playground area that is being constructed and renovated, and if someone comes out to walk around at night, it is difficult to guarantee that you will not bump into the murderer digging a pit and preparing to bury the body, which is obviously not enough insurance. If the weather wasn't so cold now, I might still consider the artificial lake," Dai Xu pointed in the direction of the artificial lake that was no longer visible in the distance, "If you tie stones to the bones and push into the lake, after all, the artificial lake is also claimed to be more than ten meters deep, and the chance of being found under the water is smaller and buried in the soil, and the rate of decay is a little faster than in the soil, but now there is a very thick layer of ice frozen on the surface of the lake, and it is safe for people to walk on it, there will be no problems, and the thickness of the ice is estimated to be almost half a meter or more. Half a meter of ice is much more tiring than digging in the soil. ”

"There are so many snowdrifts on this side of the woods, why are you so sure it's this one?" Fang Yuan looked at it, and there were only a dozen large and small snowdrifts around here.

"Snowdrifts are only one aspect, the focus is on the wheel prints of the bikes, which I told you and you can see. As for what's so special about this pile of snow...... Dai Xu took out his phone and handed it to Fang Yuan, "I took a few photos before I dug it up, you can take a look." Although this pile of snow is not the largest pile around, but you look at other piles of piles, because they are piled up layer by layer, there should be that kind of faint black and white layer division, but the situation here is a pile of snow, black black, white white, the layers are completely messed up, and the snow blocks are relatively loose together, the surface does not have the kind of hard shell surface that is repeatedly formed because of melting and freezing, and fine soil chips can be seen on the surface, which has obviously been turned over recently, and has moved the soil layer. So when backfilling, the tool is stained with soil and left on the surface of the snow. ”

"Your analysis and judgment are too accurate!" Fang Yuan praised from the bottom of his heart.

Dai Xu touched the back of his head a little embarrassed: "Actually, I'm not sure if I'm right in my judgment, so I still think, if I don't dig it out, I won't admit it, otherwise it will be too shameless." ”
