According to the preliminary judgment of the forensic doctor of the time of death of the deceased, plus the approximate time when Duan Feiyu ran away from home, the surveillance video records they need to collect should also be two to three weeks ago, which is not a simple matter, because within that range, many monitoring equipment is not official, and some street buildings and shops have installed their own security facilities, although they are required to cooperate, and there is nothing to retrieve the records, but they have no choice but to ask for a long time for Dai Xu. Many private institutions install monitoring equipment that does not have the provisions to keep so many monitoring records, many private shops are only kept for a week, and some large office buildings will be kept within two weeks, and it is not easy to collect more than two weeks.

This is also an objective situation, although it is not ideal, and there is no way, Dai Xu and all of them can only be in the attitude of talking better than nothing, and the longest can be pushed backwards to whichever day, they will be saved until about a week away, and they are all transferred out, and they dare not carry or be sloppy.

After tossing these work, it was already seven or eight o'clock in the evening, because some office buildings or individual shops had already closed down, and the relevant person in charge could not be found, and the remaining small part of the area could only be left for the next day to continue to be completed, everyone returned to the bureau and met a head, and did a further division of labor, before the deceased's information on all aspects was further confirmed, it was a waste of time to directly start screening the surveillance video, so in the end, it was decided that Dai Xu and Fang Yuan would stay and wait for the news from the forensic doctor. The others went back to rest. The rest of the work is left for the next day, and there is no need for everyone to spend here.

So the others left after work, and Dai Xu also went outside to buy two meals and came back. He Fang Yuan ate in the office, even if the problem of dinner was solved, during the meal, Dai Xu also picked up the fitness foot-binding sandbag on the table with evidence bags from time to time to take a closer look, and the two dumbbells were also placed on his desk, but that thing was a little heavier, so he didn't pick it up and play with it.

Fang Yuan knew that Dai Xu must be pondering something. And it must be related to the case, otherwise he wouldn't have fiddled with these things from the deceased while eating, after all, he didn't think about or talk about work when he ate in the past. This is Dai Xu's own principle, because he has always advocated the combination of work and rest, and he must know how to change his mind in a timely manner, so now he himself takes the lead in breaking the vows. It is enough to see how much attention he attaches to this case. It is estimated that the first day before was nothing, which did give him a lot of invisible pressure.

"Is there anything special about these things?" Fang Yuan didn't want to ask, but she saw Dai Xu pick up the four fitness sandbags one by one and weigh them one by one, and then carefully looked through them for a long time, and then finally couldn't help it, she put aside the lunch box that she had eaten half-eaten, stood up and took a sandbag over to take a look.

"The most special thing about these sandbags is that they are so ordinary. And it's very new," Dai said with a smile to Fang Yuan. "If you look at the fabric on the surface of this sandbag, I guess you girls know a little more about these things than we men, and this material is very fluffy."

Although it was separated by the evidence bag, but through the transparent bag, Fang Yuan could still distinguish the material of the sandbags that tied the feet, not to mention, these things are really the kind of fabric materials that are easier to fluff, Fang Yuan had bought a similar one when he was in school before, at that time, he had just ignited his determination to lose weight, and went to the playground to run every day, in order to make the exercise effect more obvious, she listened to other people's suggestions, and planned to buy two lighter small sandbags to put on her wrists, but because of the limited cost of living, So her choice space is not very large, and finally turned around, in the sporting goods area of a supermarket near the school, I selected a pair of cheapest small sandbags, the material is very similar to the evidence bag in front of me, I wore it for a few days, and it was hairy on it, and then used it for a few days, the hairs were tangled together, forming small bumps, it looked like how cold it was, she also had to use small scissors to cut off the small bumps on it one by one, Rao is so, within a few days, the materials will still fluff again, and then form new pimples, Cycle after week, until she ran to lose weight had no effect at all, and in a fit of anger, she entered the "cold palace" together with the two small sandbags, and disposed of it before graduation.

"So, it's very likely that these four gym foot-binding sandbags were newly bought?" Fang Yuan immediately understood what Dai Xu meant, "The purpose of buying it is to fall into the victim's limbs, so that the victim has no way to float out of the water?" If that's the case, then is it necessary for us to go to Ke Xiaowen and their high school to find out, see if there are any stationery and sporting goods stores, check if there is the same brand selling over there, and can the boss remember what the people who have bought this kind of thing look like recently? ”

"You're right, but it's not just the stores near the high school, but also the periphery, the surrounding comprehensive supermarkets, sporting goods stores and other places need to go to see, these two dumbbells, are also quite new, like this kind of dumbbells with paint treatment on the surface, if after a period of use, after bumps, the surface may have paint falling off, even if it does not reach the level of falling off, at least there will be some scratches, but these two are not," Dai Xu pointed to the weight mark on the side of the two dumbbells," Five-kilogram small dumbbells, said to be heavy or not heavy, said light or not, the volume is not large to carry, the weight is generally lifted, not difficult, but it is enough to make people drown after there is no way to float smoothly, and this thing is also different from the control knife, anyone who wants to buy can buy it, no one will pay attention to it at all, and it is easier to fix it on the body than a stone. So the murderer must have deliberately bought these things for his own ultimate goal, but there is another issue that needs to be considered, no matter how inconspicuous things are, after reaching a certain amount, they will always become very eye-catching, so I think the murderer spent so much thought on the question of how to keep the deceased's body from coming to the surface, and he must not not think about hiding himself, so he may not buy it in the same place. ”

Fang Yuan nodded convincingly. I'm afraid this is one of the aspects she admires most about Dai Xu, a lot of things, or a lot of clues. In fact, as long as everyone thinks and ponders with their hearts, is careful enough, and attentive enough, they will always think of it, and Dai Xu's excellence lies in the fact that he is always one step ahead of others and wants to go ahead of others. While others had only considered the first level, he had already thought deeper and farther.

Working with such a person, for Fang Yuan's desire to progress. In terms of the personality that can be improved, it is tantamount to a kind of pressure, and in a short period of time, it will take a lot of effort to catch up with him. It's even harder to surpass him. But Fang Yuan didn't feel frustrated because of this. First of all, the reason is naturally inseparable from Dai Xu's encouragement and inspiration, he has never been afraid of others catching up with him, especially for Fang Yuan, he is even more happy to see her progress, so he will never have reservations about her, secondly, Fang Yuan doesn't know if this is his own innovation, she likes to be around the strong. Seeing the gap between each other will make her more motivated to catch up. If she is allowed to be with a person who has a mediocre job and doesn't care, even if she won't be affected to become slack together, at least she won't have as much energy as she is now.

"But I'm afraid it won't work tonight, it's too late, it's too late," Dai Xu looked at the time, it was already nine o'clock in the evening, "This time, not to mention the small shops, the supermarkets are closed, so I can only leave it until tomorrow." And if I'm not mistaken, the brand of these two things should be quite extreme, or it is very cheap, but many stores do not sell it, or even if the price is moderate, almost every store has to sell it. ”

Fang Yuan thought for a while: "Then I'd rather encounter a very cheap situation, but many stores don't sell it, so it's either empty, once there is a harvest, it will definitely be valuable, it's better than a lot of ambiguous, specious information, it's better to say a little bit in a big supermarket, it's good to have monitoring at every cashier, I just don't know how long the image data will be kept, it's not easy to say about small shops, especially those who sell sports equipment, it is very likely that they won't install monitoring equipment at all, anyway, what they sell, or it's worthless, Otherwise, it is valuable, but the volume and weight are also considerable, and it is not realistic for ordinary people to take it secretly. ”

"yes, I'm afraid this really depends on our luck!" Dai Xu said with a smile, pushing things aside after speaking, and pointed to the unfinished lunch box in front of Fang Yuan and himself, "Eat quickly, if you don't eat again, it will be really cold, I can be regarded as setting a bad example in front of you today, I didn't eat well." ”

"I don't have many opportunities for you to set a bad example for me when it comes to eating and drinking, so I think it's good to have once in a while." Fang Yuan joked casually with him, no matter what, the male corpse was finally salvaged in the artificial lake in the park, this harvest could be regarded as helping them unload a big stone from their hearts, although they were a little tired from being busy now, but their mood was much better than when they had lunch.

As soon as the two of them finished eating, the forensic doctor called, saying that the corpse had been autopsied and some preliminary conclusions had been drawn, Dai Xu and Fang Yuan hurriedly went over to find Forensic Doctor Liu and asked him about the situation.

"Yo, Forensic Doctor Liu, it's a misfortune that we're here, you eat first, and then you'll talk after eating." As soon as Dai Xu entered Forensic Doctor Liu's office, he saw that he hadn't finished eating, so he didn't hurry to ask and sat down with Fang Yuan.

Forensic Doctor Liu waved his hand: "It's okay, it's okay, didn't you just finish it, I'm hungry, they helped me buy the food back and put it here, I just thought about hurrying up and taking a bite, have you eaten?" You've just finished your work, right? ”

"Yes, we just came back for a while, we finished eating, you eat first, don't worry." Dai Xu and they worked hard, and Forensic Doctor Liu was not easy for them, especially Forensic Liu was not the same age as them, so Dai Xu was embarrassed to affect other people's meals no matter what.

"Don't delay, I'll eat while we talk." Forensic Doctor Liu said as he pulled rice into his mouth.

Fang Yuan's expression was slightly embarrassed and looked at Forensic Doctor Liu, and then looked at the lunch box in his hand: "Let's talk about it after eating in a while, will it be ...... to talk about this kind of topic during dinner?"

If it was usual, the corpse this time was really a bit lethal, it looked like one thing, if he got closer and smelled it, it was another matter, now when he thought of the appearance of that corpse when it was salvaged out of the water, Fang Yuan still couldn't help but feel that a faint rancid smell seemed to come into his nose, mixed with the unpleasant smell of stinky water and mud, and his stomach was not disgusting, but it was not very pleasant.

"Don't worry about me," Forensic Doctor Liu heard what Fang Yuan was trying to express when he was embarrassed to finish, so he smiled, "If I had just joined the company, it might not be very good, now for so many years, I have already boiled it out, this kind of can still be carried out, and I have seen a lot of heavier tastes than this." ”

Since Forensic Doctor Liu said so, Dai Xu didn't intend to continue to pretend to politely resign with him, so he asked Forensic Doctor Liu to ask the question he was most concerned about while eating: "Is it suicide or homicide?" ”

"He killed," Forensic Doctor Liu replied very simply, "After the autopsy of the deceased, we can be very sure that the deceased did not drown, but after being killed, he tied up the burdens and pushed them into the lake, which can rule out the possibility of wanting to find a short-term suicide and tying the weight to throw himself into the lake." ”

"And what was the cause of death?" As soon as Fang Yuan heard this, her heart could be regarded as a stone falling to the ground, she was actually very worried before, in case it took so much effort, the male corpse that was finally salvaged was finally forensically identified, and it was just a short-term suicide by herself, then the previous excitement would become empty joy, in that case, whether Duan Feiyu was dead or alive, there was still no way to draw conclusions, this was very difficult to do.

"It should be poisoned, and from the condition of the deceased's organs, he should have suffered a certain amount of pain before he died, we examined the deceased, and found no fatal trauma, and then after the autopsy, a small amount of liquid residue was extracted in his stomach, and now it has been sent to the laboratory for testing, it is estimated that it will not take long to draw conclusions, and then you can tell what kind of poison caused death." Forensic Doctor Liu replied. (To be continued......)
