"The party group documents of the district bureau have come down, and Comrade Lin Shu officially came to our team as an intern to help, and his position was hung on the side of the forensic department to assist Xiao Zhou in following up the scene and the autopsy." Xing Xie rarely smiled, raised his cup to Lin Shu and said, "Although I don't like you very much, I still want to congratulate you on joining our criminal investigation team." Tomorrow, all the people who take turns off will give me drink, and those who want to be on duty will replace the wine with tea, and give me this stinky boy to drink one by one before I can leave. ”

That night, Lin Shu, who didn't know how many cups had been poured into it, returned to the police dormitory with Xu Rong's support. Because the school is out of class, Lin Shu quit the original rental house and moved into the police dormitory, the dormitory is not big, but the conditions are good, one bedroom and one living room, independent bathroom, and a small balcony. Glancing at Lin Shu, who had just returned to bed and fainted directly, Xu Rong helped him cover the quilt and closed the door and left.

"Bang bang bang", there was another rapid knock on the door, and Lin Shu, who had a splitting headache, even suspected that his soul had penetrated into Ma Dongsheng's case. He got up with difficulty and opened the door, and found that it was Zhou Yinglin, Lin Shu looked at his phone and said, "Forensic Doctor Zhou, why are you here, isn't it just past 7 o'clock now?" ”

"I live next door to you." Then Zhou Yinglin shook her head and continued: "No, that's not the point, the point is that I need your assistance, can you wash up for fifteen minutes?" ”

Looking at Zhou Yinglin's sincere eyes through the lenses, Lin Shu was stunned for a moment, he closed his eyes and took a deep breath to sober himself up, then opened his eyes and nodded vigorously.

Fifteen minutes later, thinking that it was the first scene he had come to the forensic department after all, Lin Shu, who was sitting in the co-pilot, looked at Zhou Yinglin, who was driving, and said, "Forensic Doctor Zhou, what did you mean when you just said that you needed my assistance?" ”

"Don't forensic doctor Zhou forensic doctor shouted like this, it's too rusty, call me hard brother in the future." Then he handed Forensic Doctor Zhou's mobile phone to Lin Shu, "You've seen this and you'll know why I need your help." ”

"Hard ..... Hard brother? Lin Shu, who took the phone, was very surprised by the name.

"Yes, in the past, I don't know who called my Ying character into a hard word, and then said that I studied forensic medicine like a boy, and then gradually developed into the name of hard brother, isn't it very handsome."

Lin Shu looked at the soft girl in front of him, in her twenties, about 1.11 meters tall, with medium and long hair, big eyes, bright eyes and bright teeth, fair skin, and a pair of glasses. Then he shook his head and looked at the photo on his phone, which showed a highly ossified corpse, with little muscle tissue on his body, and traces of animal bites.

"You have also seen that there are cases of high ossification and destruction of corpses by animals, although there are many cases of injury judgment and unnatural death judgment that I have handled, but this kind of corpse with almost no flesh is also rare for us, so I would like to ask you to use your professional knowledge to accompany me to the scene."

Lin Shu didn't speak, nodded and continued to look at the photos of the scene on his phone.

I don't know if it was because I drank too much last night or because Zhou Yinglin's car was too stable, Lin Shu fell asleep unconsciously.

Two

"Wake up. Why are you asleep again? ”

Feeling that someone was slapping his face, Lin Shu slowly opened his eyes and saw the person in front of him clearly, "Hard ...... Hard brother, I'm sorry I'm asleep again. ”

"Are you dreaming again, are you dreaming of any key information?"

Lin Shumeng saw the key information and promoted the investigation of the case, which had already been passed on by Xu Rong at the newcomer celebration last night, and everyone in the entire police station knew about it.

Lin Shu nodded helplessly, "It's a fish in the water." Although he didn't say it, Lin Shu still appeared in the sea of fire in his dream as usual. He distinctly felt that this time the strength was a little stronger than the last time, and he felt that a few more times he might be able to completely manipulate that body in his dreams.

Lin Shu, who was still indulging in reminiscing about the dream just now, was suddenly patted, "This time you guess the dream is wrong, the body was found in a cave, there are no rivers and lakes within a few kilometers nearby, it should be difficult to find a fish in the water." Let's go, don't be in a daze. ”

Lin Shu got out of the car to help carry the toolbox and followed Zhou Yinglin to the mountain, which looked like a natural mountain road, and was artificially stepped on a shallow and deep step. Surrounded by pine trees, lush and full of life, the trees seem to form a natural barrier to the entire hillside, and there are few signs of human activity nearby.

After walking for about five minutes, it seemed that we had already arrived at the place, and it was surrounded by a police cordon, the only difference was that it seemed that the people standing inside were wearing thick protective clothing.

"What's going on, why do you have to wear protective clothing?" Lin Shu asked puzzled.

Zhou Yinglin didn't answer, but handed Lin Shu a set of protective clothing, and then began to put it on herself.

The two dressed approached the cordon, Zhou Yinglin showed her police ID card to the police at the scene, and the police picked up the walkie-talkie and reported. Then a big brother who seemed to be the person in charge came out of the cave in front of him, stretched out his arm and shook hands with the two forensic professionals of the Criminal Investigation Brigade, "I am the deputy director of the Xunyang Town Police Station, my name is Wu Zhihua, hello comrades of the District Bureau, because it is the first time we have seen such a corpse, and we don't know where to start, so we asked the District Bureau for assistance, thank you so much for coming." ”

"Don't say that, we're here to learn." Zhou Yinglin said politely.

The two followed Director Wu into the cave, and before they could see the whole cave, a particularly thin figure suddenly walked over.

"We've tested the radiation levels all over the cave, all of them are below 300 rem, and we've also tested the parts of the corpse, which are normal, but just in case, you can do a preliminary autopsy here, and then we'll do a detailed test of the bone meal scraped off the corpse."

"It turned out to be Qi Xin, you are really too thin, I almost thought it was a protective suit floating."

"I can't help it, I can't get fat no matter how I eat, I also want to have a figure like Sister Lin." Qi Xin, who was talking, smiled playfully, and did not forget to touch Zhou Yinglin's body with his hand.

Just when the two girls were fighting, Lin Shu finally saw the whole picture of the cave. The cave is not big, about 10 square meters, the corpse is located on the southwest side of the cave, sitting against the wall, the head is largely decomposed, the skull can be seen, the hollow eye socket can also see the shriveled eyeballs, the mouth and nose cavity are so corrupt that only a layer of skin remains, the face of the deceased can not be distinguished, the chest and abdomen appear soft tissue liquefaction and there are traces of being bitten by animals, part of the sternum and ribs are exposed, the traces of the lower body being eaten by animals are very serious, Bai Sensen's leg bones look eerie under the illumination of the lamp, and some muscles are still attached to the tibia. But the most different thing from the other corpses was that the bones of this corpse shone faintly fluorescent, as if surrounded by fireflies, which was very obvious in the dark cave.

"This protective suit is really heavy, and I feel that it greatly affects the work efficiency." Zhou Yinglin, who was squatting next to the corpse, said with some complaints.

"That's no way, the bones of the corpse are fluorescent, it may have been exposed to some radioactive materials, let's complete the autopsy report as soon as possible."

"Well, I'll dictate the situation, and you can record it, and if you think there's something wrong with what I said, you can raise it." Zhou Yinglin threw Lin Shu a stack of sketch paper.

"Judging from the symphysis pubis and the growth of teeth, the deceased was about 31 years old, female, thin, and the body was 165cm long." After speaking, he also glanced at Lin Shu.

At this time, Qi Xin also came over and said, "She should have been dead for a short time." ”

Lin Shu nodded to Zhou Yinglin in agreement, "It's hard to say, the high temperature and rainy environmental factors in summer, as well as insects and scavengers in the mountains, will accelerate his soft tissue liquefaction and white ossification. ”

Zhou Yinglin continued her work, "The deceased had obvious wounds on the neck, and from the residual muscle and skin, there were life reactions at the wounds. This should be a fatal wound. There are obvious trailing marks at both ends of the wound and multiple flaps formed, it seems that the murderer is very emotional. ”

"There are defensive injuries on both hands, palms and radius, which proves that the deceased had fought with the murderer." Lin Shu added. Then, as if he had seen something, Lin Shu suddenly took out his tweezers and picked up some thin white threads.

"What is this?" Qi Xin asked with some curiosity.

"The eggs of the big-headed goldfly. It's summer, and the temperature is about 30 degrees Celsius, so it takes about 10 days to get from an ovitable. Lin Shu said as he packed the precious eggs in the physical evidence bag. In other words, the time of death should be within ten days, and I have to go back and do a mock control experiment to get the exact time. ”

Qi Xin didn't want to continue the topic, "Now that the cause of death has been guessed, and the time of death has a general direction, then who told me why she was as bright as a light bulb." ”

You look at me, I look at you, and no one has an answer.

may think that there is no result if he continues to struggle, Lin Shu can only continue to push forward the work, "The face can't be distinguished, does the physical evidence at the scene have useful identity information?" ”

"The deceased had nothing to prove his identity, nothing but the clothes on his body. I have asked Director Wu to arrange for someone to expand the scope of the search. Qi Xin shook his head.

Zhou Yinglin thought for a while and continued: "Then you extract valid DNA first, and then see if you can extract fingerprints, and then take back the deceased's dental information and compare it with the records of nearby dental clinics, I hope there will be results." ”

"The fingerprints are estimated to be helpless now, either they are decomposed or dehydrated and shrunken, let's take a look at them after the body is transported back to the district bureau." Qi Xin said as he took a sample of the corpse and took pictures.

"If the deceased is concerned, maybe when the body is transported back, I will ask one of my senior brothers to try it." Lin Shu said with some uncertainty.

After completing the autopsy report one after another, the three of them left the cave, said goodbye to Director Wu and began to return to the Public Security Bureau of the High-tech Zone. The rest of the work can only be carried out after the results of the nuclear radiation analysis of the corpse bone meal show that it is safe.

Lin Shu, who returned to the forensic building, began the simulated breeding experiment of the big-headed goldfly, which was a method of cultivating a batch of eggs of the big-headed goldfly by restoring the temperature, humidity and other environments at the scene of the crime, and comparing the eggs found at the scene to determine the exact time of death.

Half a day later, not long after the nuclear radiation safety report of bone meal came out, the corpse sister from Xunyang Town was sent to the forensic building of the Public Security Bureau of Anyang High-tech Zone. This time, it was Forensic Zhou who was in charge, and Lin Shu acted as a deputy and recorder.

Although it was not the first time that Lin Shu had come into contact with a corpse, the smell of such a highly corrupted corpse still made him frown, "I didn't feel much of it because I was wearing protective clothing at the scene, and now after the thaw, I smell it, and I'm a little close to death." ”

The police officer in charge of the video also made a retching sound in due course to express his agreement.

Although the neck wound of the corpse may no longer be used to reverse the murder weapon due to factors such as decay and animal influence, Zhou Yinglin still took out a ruler to measure the length and depth of the wound, and then cut the clothes on the deceased's body.

The soft tissues of the abdominal wall and the omentum of the corpse have long been gone, and the remaining internal organs are scattered in the abdominal cavity, which saves a lot of trouble. Zhou Yinglin, who was standing on the right hand side of the supine position of the corpse, gently cut open the chest cavity of the deceased, separated the remaining chest muscles, quickly cut off the junction between the costal cartilage and the ribs, and lifted the sternum to slowly cut the connected tissues.

Looking at the open chest, Zhou Yinglin and Lin Shu were carefully observing the situation of the corpse, hoping to find some clues that would help the case, but unfortunately there was nothing. There was no damage to the thoracic organs, and the subsequent craniotomy did not contain any useful information.

Four

As the autopsy ended, it began to get dark, and the results of the autopsy made Lin Shu very frustrated, and he still thought that his first work in the forensic department would get off to a good start.

Came to the office of the criminal investigation team with the autopsy report, and Zhou Yinglin and Lin Shu, who were about to inform the Xing team of the autopsy results, saw that the Xing team was sitting on the sofa at this time, and Wu Zhihua and a man in his fifties who looked like a farmer were sitting opposite.

"Team Xing, I am Wu Zhihua, deputy director of the Xunyang Town Police Station, this is the informant and the forester of the pine forest at the scene of the crime."

The peasant-like man looked honest and said in non-standard Mandarin, "Hello Captain Xing, I am the forester of that area, my name is Wu Peng, I basically patrol that forest every day, and by the way, I pick up some pine nuts and go home to extract oil." This morning I got up at five o'clock and went up the mountain road, and soon it started to rain lightly. I went to the cave as usual to hide from the rain, and I saw that. Wu Peng may have recalled the original picture, with a frightened expression on his face.

Xing Xie pondered for a moment and asked, "Then when was the last time you went to this cave, and did you find anything abnormal?" ”

"Three days ago at noon, it was raining that day, and I went there to hide from the rain, but I didn't see anything." Wu Peng recalled.

Lin Shu checked the weather and confirmed what Wu Peng said, "It did rain in Xunyang Town at noon on the 16th. ”

"Does that cave usually go to a lot of people?"

"Hardly everybody goes, except for me, some hikers might go there to rest, but not much."

Xing Xie nodded, and found that there were no more clues to obtain, "Okay, thank you for your cooperation, let's do this today." Then he said to Liu Jianjian: "Lao Liu, you send this fellow back." ”

After sending Wu Peng away, several people returned to the office to discuss the case.

"Who's going to come first?" Xing Xie handed over the decision.

"Let's go first, after all, there's not much to say." Zhou Yinglin sighed and said, "The deceased is a woman, 31 years old, thin and 165cm tall. We found no injuries other than a cut on the neck and a defensive wound on both arms. Through the evaluation, our forensic department agreed that the large amount of blood loss caused by the cut of the carotid arteries on both sides of the neck was the cause of death or one of the causes of death. The neck wound was caused by repeated cuts with a sharp object, and it can be seen that the murderer either hated the deceased very much, or wanted to ensure that the victim must die. It's gone, it's your turn, Qi Xin. ”

"Yes." Qi Xin replied and then walked to the whiteboard with a pile of materials, "We worked in pairs with the Xunyang Town police to conduct a circle search within a radius of 100 meters with the crime scene as the center, but we didn't find more useful information. After speaking, he didn't forget to glance at Wu Zhihua.

Wu Zhihua nodded and said, "Our police subsequently expanded the search range to 500 meters, but still found nothing." ”

"According to our splicing results, it can be concluded that the deceased was wearing purple silk underwear, black tight sports elastic shorts on his lower body, gray sports bra and black tight crop top on his upper body, a pair of black socks on his feet, and a pair of white Nike sneakers." Qi Xin said as she pasted the photos one by one on the whiteboard.

"At the same time, we took the fingerprints of the deceased, but unfortunately we did not find a match. The dental information is still being compared at the dental hospital, but there is no result for the time being. ”

Hearing this, Lin Shu asked a little strangely: "Didn't you say that the deceased's hands were either rotten or dehydrated and shrunken, and fingerprints could not be extracted?" ”

Qi Xin's face was full of words that were about to praise me, "I found a finger that was still intact, rehydrated the dehydrated skin with a fabric softener, and removed the attached static electricity, and I got a complete fingerprint." ”

The whole team looked at this living treasure and smiled unconsciously.

"What's the reason for that glowing bone?" Zhang Dong couldn't help but ask.

Hearing this question, everyone present became interested, after all, the glowing corpse was really unprecedented.

"It's Vibrio, and some strains of Vibrio cholerae emit light. After the deceased was infected, it became like this under the action of luciferase. Qi Xin continued: "For such a large area of luminescence, two conditions must be met. ”

"Which two conditions?" Xing Xie asked immediately.

"Vibrio cholerae is commonly found in the ocean, so the deceased had been exposed to seawater before his death, and there were huge wounds in the area of contact."

Lin Shu struggled to recall the knowledge he had learned in his pathology class, "Vibrio cholerae infection is accompanied by violent vomiting and diarrhea, and the deceased should have been exposed to the sea shortly before his death, and the symptoms had not yet appeared, otherwise it would be impossible to go out in a sportssuit." ”

After listening to the reports of the forensic department and the trace examination department, Xing Xie immediately made a judgment: "We need to determine the source of the body immediately, judging from the clothes of the deceased, it should not be a resident of Xunyang Town and nearby towns, and our city is not connected to the coastline, and the search scope needs to be expanded to several neighboring coastal cities, Xiao Zhang, you immediately contact the city bureau and ask them to give support, Xiao Xiaoxiao, you plan to send a letter to the brother city, to help see if there is a match for the missing person within three days." The target is a woman in her 30s, 165 cm tall, who may have been to the beach before her disappearance and has a large wound. In addition, several comrades who had come into contact with the corpse remembered going to the hospital to get an injection, and heard that the mortality rate of cholera was very high. ”

"Yes."

Five

There was no word for a night, and it was difficult to carry out the work of determining the source of the corpse, on the one hand, the given information was too general, and on the other hand, the scope was too large, involving several prefecture-level cities.

It has been 33 hours since the body was found, and Xing Xie, who usually sits firmly in the overall situation, is also pacing anxiously in his office. Anyway, it was also a request for help from the town police station below, but after so long, the source of the corpse was not even determined.

At this time, there was a sharp knock on the door, and Xing Xie yelled impatiently: "Who." ”

I saw that the door was pushed open slightly and a head was stretched out, it was Lin Shu, "I, Team Xing." ”

"Report, I sent the information and photos of the deceased's skull yesterday to a senior brother of mine who specializes in skull restoration in human forensic science, this is his restored face of the deceased, you can take a look." Lin Shu walked forward quickly, and while talking in his mouth, he didn't forget to hand over his phone to Xing Xie.

Xing Xie, who took the phone, looked at it and asked, "What is the similarity rate?" ”

"It is difficult to say that craniofacial reconstruction is carried out based on the correlation between the morphological characteristics of the human head and facial soft tissues and facial features and the morphological characteristics of the skull, and there are certain errors. It will also be affected by acquired factors, such as diseases, plastic surgery, etc., but in general, the error should not be large. ”

"Okay, I'll believe you." Xing Xie looked at the photo on his phone and then at Lin Shu, and then yelled outside, "Xiao Zhang, upload this photo and see if you can find this person." ”

The case began to develop in a good direction, but the real turning point came on the morning of the third day after the deceased was found.

At nine o'clock in the morning, when everyone was thinking about whether the deceased had no relatives and friends at all to find out that she was missing and reported the case, an old couple came to the criminal investigation team.

On the sofa in the office, the old couple said that their daughter had been missing for a few days, they were from Fodong City next door, and they saw the photos sent by the Public Security Bureau last night and found that they looked like their daughter, so they came to confirm.

Lin Shu, who took the photo, carefully compared it and found that the old couple's daughter was indeed eighty percent similar to the picture restored by the senior brother, and then he nodded to Xing Xie. However, in order to ensure that nothing went wrong, Xing Xie still asked Qi Xin to help make a DNA match.

While waiting for the results, Xing Xie and Ning Xiaoxiao helped the old couple do some questions.

According to the old couple, since their daughter got married, they have lived separately from their daughter, but their filial daughter will still call them every other day, and even if they don't call, they will send us a message to greet them. But since five days ago, they couldn't contact their daughter, so they called their son-in-law, who also said he didn't know, and then they went to report the case, but there was no result.

After a while, the DNA results came out, and it was basically determined that the deceased was Ren Xiaofei, the daughter of the two old men. Hearing this, the old woman fainted on the spot, and the old man also sobbed quietly. Lin Shu once again felt the heaviness of Zhou Yinglin's words in front of the corpse room. As a forensic worker, you must have a strong psychological quality. And these qualities not only need to be practiced in the usual scene and autopsy, but also baptized in front of human feelings.

Now Lin Shu only hopes that this murder case can be solved as soon as possible, and the dead will be given peace and the living will be told the truth.

After Zhou Yinglin took the deceased's parents to the morgue to identify the body, Xing Xie immediately launched the deployment: "Immediately go investigate the information of the missing person, retrieve the call records and chat information of her mobile phone, and check the surveillance near her home, I need to know when and where the deceased last appeared." We can't let the real culprit escape for one more day, and we must give an explanation to the parents of the deceased. ”

"Yes."

"Also, what's going on with those bugs of yours?" Xing Xie asked the pensive Lin Shu again. "Do you know the exact time of the crime?"

"I'll check it out now."

Six

On the afternoon of the day after the deceased's parents identified the body, the office of the Criminal Investigation Brigade held a final seminar on the facts of Ren Xiaofei's case.

Zhang Dong first stood up and said his findings: "According to the surveillance video near the victim's home and along the way, we restored the victim's route, at about 7 o'clock in the morning on the 17th, Ren Xiaofei left her home by car, and drove to the direction of our city through the ring highway, and was photographed at 8:33 for the last time after parking on the village road in Xunyang Town and walking away in the direction of the crime site." Ren Xiaofei in the surveillance footage is dressed the same as when she was killed. ”

Lin Shu also proposed at the same time: "The results of my insect egg simulation control experiment show that the eggs on the deceased are the closest to the 48-year-old eggs I cultivated under the same environmental conditions, and I started cultivating them at about 9 am on the 19th, and the time when the deceased was killed should be between 7 am and 11 am on the 17th." ”

In other words, the time of death should have been between 8:33 and 11 a.m. on the 17th. Find out why the victim went there? Xing Xie asked again.

"We extracted her chat records by contacting the operating company of Ren Xiaofei's commonly used chat software, and found that a person named Li Hong made an appointment with the deceased on the afternoon of the 16th, and judging from the chat records, the deceased had an improper relationship with this Li Hong." Ning Xiaoxiao took out a few screenshots of the chat for everyone to circulate, "We think that Li Hong is suspected of committing a major crime, and Uncle Liu has already brought someone to control it." ”

Xing Xie immediately dialed Liu Jianjian's phone to inquire about the situation, but then his disappointed expression seemed to predict that the real culprit was not this Li Hong, because he had acute gastritis on the night of the 16th, and now he is still lying in Fodong Central Hospital.

Xing Xie stroked his beard again and thought, "What about Ren Xiaofei's husband, I think he is also very suspicious of committing a crime." ”

"It's true that even parents who don't live in the same household can find out that their daughter is missing, but the husband who lives with them doesn't notice anything?" Lin Shu also agreed.

Zhang Dong immediately checked it on the computer at this time, and then said: "Ren Xiaofei's husband Huang Hui flew to Linjiang City at 10:15 this morning. ”

"Immediately contact the local public security and cooperate with the arrest of Huang Hui."

"Yes."

When Huang Hui saw that the police found him, he seemed to know that he couldn't escape, and he explained everything to 1510.

Because Huang Hui was not in good health, Ren Xiaofei hooked up with fitness coach Li Hong very early, and Huang Hui didn't know about it until the evening of the 16th, when Li Hong sent Ren Xiaofei home and was met by Huang Hui. But who would have thought that Ren Xiaofei was not only afraid, but ridiculed Huang Hui for his weak body, and forced him to divorce and divide half of his property. That night, Huang Hui secretly opened Ren Xiaofei's mobile phone while she was taking a shower, and found that the two had a tryst at the place where the crime occurred. At this time, Li Hong sent a message saying that he was unwell and would not be able to go tomorrow. Huang Hui thought about it and came up with a plan, he first secretly deleted the chat history of Li Hong's unwellness to create the feeling that the date would continue tomorrow. Then on the second day, he went to Xunyang Town early with the murder weapon and waited for Ren Xiaofei's arrival......

"So how did the deceased get Vibrio cholerae?" Zhou Yinglin, who was sitting in the cafeteria, asked puzzled.

"It seems that I went to the beach and was cut in the thigh by a sea fish." Ning Xiaoxiao said while chewing the meatballs in her mouth.

"It's really a fish in the water." Zhou Yinglin looked at Lin Shu with a smile.

"What fish?" Ning Xiaoxiao also looked at Lin Shu and asked with a puzzled expression.

"No, no, Brother Hard said she wanted to eat fish." Lin Shu didn't want to be dissected as a monster yet.
