[Thank you Rozenholly for dropping pink tickets!] Hug! 】

Both sides of the railway are particularly dark, because the terrain is relatively open, there are no buildings around that can even be sheltered, so the wind is also very strong, and it is also very cold, Fang Yuan and Dai Xu one is on the left side of the railway, one is on the right side of the railway, shining a flashlight under their feet and around, looking carefully, there are some debris on both sides of the railway, but many of them look like some garbage and debris that have been thrown out of the train passing from here, the two people have been looking for a long time, until the sky begins to shine slightly, and they still haven't found it, although there is no snow in late autumn, But in the early hours of the morning, the wind blowing for several hours in this uncovered outdoor still made people feel cold from the inside out, Fang Yuan's hand holding the flashlight was already a little wooden, and he felt that the temperature on his body was being carried away by the wind little by little.

"Forget it, don't look for it, we've already found it so far in both directions, it seems that the murderer didn't handle the deceased's clothes so casually." Dai Xu motioned for Fang Yuan to come over, at this time the sky was already bright, even if he didn't use the flashlight to illuminate, he could see the things around him clearly, the two of them had already looked for two or three kilometers along the railroad tracks in two different directions, and they didn't see any trace of clothes, so Dai Xu felt that there was basically no possibility of this search direction, and there was no need to waste time on this.

The two walked back to the place where the mortuary was stopped, where the scene had been basically processed, and the body was packed in a body bag and transported back by car, after all, after dawn, there might be passers-by or employees of the attached factory around, and there was no need for them to see the body. Needless frightening again.

Before he was about to finish and leave, Fang Yuan suddenly noticed the ditch on the side of the railway, the roadbed of the railway was a little higher. There is a small ditch between the road and the small ditch, and at intervals above the small ditch, there are several cement slabs paved on it, which are used for people to walk across the ditch and cross the railroad tracks, and you can take a shortcut to the railroad tracks, but the ditch is not wide. It's just over a meter, and even if there is no small bridge paved with cement slabs, most people can easily cross it. There are also man-made cement ditches on both sides of the ditch. The water in the ditch is not deep or shallow, and the position is much lower than the ground, and the water is flowing water, but it is very turbid. Squatting on a cement slab. When you get closer, you can smell the rancid smell of silt.

"You say, is it possible for the murderer to throw the clothes of the deceased into such a ditch? What if the water below is quite deep? And you see, the water is so cloudy that you can't see anything when you throw it in. Fang Yuan called Dai Xu over, pointed to the turbid and flowing dirty water in the ditch, and guessed himself.

Dai Xu looked around, and then looked at the ditch in front of him. After thinking for a moment, he walked around. Found a small branch more than one meter long, squatted on the edge of the ditch, stretched out his arm to insert the branch into it, and found that he couldn't probe to the end, so he nodded: "I think it's feasible, look for it and try it, the water in this ditch is not shallow, but the water flow is not urgent, the clothes worn in this season, if they are stained with water, they will not be too light, even if they do not sink to the bottom, they can't float far, but if they sink, the water is too turbid, and it may not be easy to find." ”

So Dai Xu found a few more people, everyone took the tools and began to look for it along the ditch, don't look at the ditch is not wide, but the ground is covered with silt and stones, especially as soon as it is stirred, the sludge under the ditch will also surge, making the water more turbid, nothing can be seen clearly, little by little temptation, little by little to find, a search is more than an hour, as more and more sludge is stirred up, the ditch also began to emit a strong rancid smell, and among the people who were looking for it, some people began to complainAfter all, the big guys get up in the early hours of the morning and come out in the cold wind, and now they are all cold and hungry, and now they can't go to breakfast, but have to stir up the stinky ditch here, and the taste is really not very pleasant.

Hearing someone complaining in a low voice, and then looking at the situation in front of him, Fang Yuan's face also became a little embarrassed, and he looked at Dai Xu a little crampedly: "Is it not quite right what I just thought...... Otherwise......? ”

"There was nothing wrong with what you thought just now, but what you think is wrong now." Dai Xu shook his head, "When we go out of the scene, we should have ruled out all possibilities, you think of the direction of the ditch, which is completely correct in itself, if anyone has complaints, it can only be said that the person's personal consciousness is not high enough, and it has nothing to do with you." ”

Fang Yuan nodded, didn't say anything more, and silently continued to look for it.

About half an hour later, everyone divided into two groups, along the edge of the ditch all the way to find, has found out about three or four kilometers away, seeing that the ditch is about to turn into a factory yard wall, and finally they found a lump of wet and dirty clothes in the mud, hooked up with a stick, spread on the ground against the pungent stench to check it, found that it was a sportswear top, plus a sports pullover, the style is relatively ordinary, sportswear tops have no brand, from the appearance and color of the look, It is possible that it was a school uniform, and the pair of sportswear pants worn by the deceased were a set, and the two clothes were wrapped in several large stones, presumably to add weight, so that the clothes could sink directly to the bottom of the water and sink into the mud to hide people's eyes.

With the harvest, everyone's feelings naturally improved a lot, put the two wet and smelly mud clothes into a bag, ready to take them back to the public security bureau together, busy all morning, now it is a temporary end, the group got into the car separately, left the scene, and returned to the main city.

Dai Xu didn't go back to the Public Security Bureau directly with Fang Yuan, but turned to a breakfast shop near the Public Security Bureau, asked for a few fried dough sticks and two cups of hot soy milk, and the two of them sat down to fill their stomachs, busy all morning, and now they are hungry.

Half a cup of hot soy milk drank down, Fang Yuan felt that the whole person was warm, while biting the fritters, pondering, she always felt that the sportswear jacket found from the ditch looked quite familiar, but for a moment she couldn't remember where she had seen it, and she tried to recall, but she actually forgot to chew the fritters in her mouth.

Dai Xu stared at her for a long time, and saw that she didn't react at all. couldn't help but feel funny, and stretched out his hand and shook it in front of Fang Yuan: "Soul Recovery!" If you don't return to your soul, soy milk will be drunk in your nose! ”

Fang Yuan suddenly came back to his senses. Only then did she find that she had a mouthful of fritters in her mouth, and she had been stunned for a long time, her face was red, and she hurriedly ate the fritters in her mouth in two bites, and then said to Dai Xu: "I think the style of that sportswear seems to be quite familiar, and I feel as if I have seen it somewhere, but I can't remember it very well." ”

"It can't be the same as your tracksuit from high school, right?" Dai Xu asked. Because the deceased was a little older than a junior high school student, plus a set of sportswear and sneakers. Therefore, almost everyone's initial speculation is that this person may be a student in high school or vocational high school.

Fang Yuan shook his head: "No, of course I can recognize what kind of school uniform the high school I attended, and our high school is very lazy." I saw a few high school students on the street the other day wearing school uniforms after school. The clothes are exactly the same as when we were back then, so I will never admit mistakes or remember clearly. I do vaguely remember that the style is a little familiar, I should have seen it somewhere, but I am not impressed, it may be that I have seen it somewhere in a hurry, and it feels as if I can remember it immediately, but I can't remember it. ”

"Then don't think about it, the more anxious you are, the more you can't remember. Let your mind relax and relax. It may not be possible that something you want to remember will suddenly come to your mind. Dai Xu couldn't think of it after thinking about it for a long time, and he looked a little anxious, and opened his mouth to persuade her to relax.

Fang Yuan nodded, put this matter aside for the time being, and continued to finish his breakfast.

Back to the Public Security Bureau, there is no need to investigate the missing person, Forensic Doctor Liu said that judging from the condition of the deceased's corpse and corpse spots, when they arrived at the scene, the time of the deceased's death should be four or five hours, that is, around midnight, so that is to say, twenty-four hours ago, the deceased was still alive and well in the world, such a short time, it is impossible for anyone to report the disappearance, so I want to confirm the identity of the deceased, First, we want to see if there are any things that can prove the identity of the deceased's clothes found, such as ID cards, wallets, mobile phones, etc., and second, we need to look at the doctor's judgment on the age of the deceased.

The deceased's belongings, except for two stinking clothes stained with sludge, had not been found, Fang Yuan was a little puzzled, if the other party was really a student based on his age, and he was still wearing clothes similar to school uniforms, what about his schoolbag and belongings? As far as she knows, not to mention middle school students now, even elementary school students don't leave their mobile phones on weekdays, could it be that the murderer threw the deceased's clothes outside the stinky ditch and took away some other things? Will they be discarded elsewhere, or will they be taken home by the killer and hidden? If it's the latter, it's probably not easy to find it before the case is closed.

Because the body found this time is relatively complete, and the time of death is relatively short, so the difficulty of conducting an autopsy is naturally lower than the previous case of Luan Shangzhi, after the examination of the body, the forensic doctors determined that there was no fatal trauma on the body surface of the deceased, and the most suspicious thing was the needle eye in the vein of the arm, because the body of the deceased did not show any signs of poisoning, Liu Forensic Medicine decided to do a chest X-ray of the body, and it was found that it was in the heart of the deceased. There are a lot of bubbles, and these bubbles that should not be stored are the real cause of the death of the deceased.

"The murderer's modus operandi...... It's quite technical. Forensic doctor Liu said to Dai Xu and Fang Yuan, who came to inquire about the progress, "We examined the corpse and found that the right ventricle of the deceased's heart was blistered and caused the heart to stop beating, which should be the real cause of death, and we also analyzed several possibilities for the formation of those bubbles, one possibility is that the murderer artificially injected a large amount of air into the blood vessels of the deceased, and the bubbles traveled in the blood vessels, and finally entered the right ventricle, but this hypothesis has certain difficulties to operate, Because if you inject air into the blood vessels of the deceased with a syringe, it may turn into many small bubbles, and when these small bubbles circulate to the lungs, they will be filtered out by the lungs and have no chance to reach the heart. Another possibility is that the murderer may have used some kind of chemical reagent that will react after entering the blood and form a large amount of gas, such as hydrogen peroxide, which is much more successful and operable than simply injecting air into the blood vessel with a syringe, and hydrogen peroxide is not difficult to obtain. ”

"In this way, the murderer this time, the level of cultural knowledge seems to be not bad." Dai Xu said.

Forensic Doctor Liu nodded: "I can think of using this method, and then lying the body on the railroad tracks on its stomach and faking suicide, this is indeed quite a smart and cunning approach." If the train passing there was an hour or two earlier, if the train driver didn't have time to brake urgently, and really crushed the corpse, I'm afraid we wouldn't be so easy to find the eye of the needle and the bubble in the heart. ”

Fang Yuan originally listened to the conversation between Forensic Doctor Liu and Dai Xu, but when she heard Dai Xu's evaluation of the level of cultural knowledge, and Forensic Doctor Liu's statement that the murderer was smart and cunning, a picture suddenly flashed in her mind, this time, she didn't let that fleeting memory slip away, but accurately grasped it.

"I remember where I've seen that uniform!" She came back to her senses all of a sudden, and said to Dai Xu with a little excitement.

Dai Xu nodded at her and motioned for her to continue.

"Some time ago, one night when I was on night shift, I went out to a nearby Malatang restaurant, planning to pack a copy and go back for dinner, just a few high school students who came in for self-study next night, also waiting there to buy food, there were two people standing next to me, and then another one came, the school uniform is not the same as theirs, all three people know, come in and say hello, the third person is suspicious, unwilling to wait, so he left, the two people who came before casually talked a few words, one said he changed his clothes? Did you enter the key class? That said yes, this exam score entered the top 50 of the grade, so I entered the top class and changed into the class uniform of the top class. The person they said was in the top class, and the clothes he wore were exactly the same as the one we found! ”

"If that's the case, our deceased this time, is it possible that he is still a scholar?" Dai Xu muttered. (To be continued......)
