Criminal Investigation Files

At four o'clock in the morning, Lin Xiuran, who had transported the corpses back to the funeral parlor, had already started work. The two corpses were placed on two stainless steel dissection tables for dissection.The entire anatomy room has no windows, is illuminated by shadowless lamps, and is specially equipped with two super-powerful ventilation systems.

The forensic work in Nancheng is ahead of the cities. There is a modern dissection room in the city bureau, which is divided into three parts: a standardized autopsy room, a monitoring and consultation room, and a corpse storage room. It is mainly used for dissection of some difficult corpses. However, since it is more troublesome to transport the corpse between the funeral home and the city bureau, the cause of death is relatively certain. The corpse waiting to be buried will be processed in the funeral home's autopsy room.

Since there were two dead, in order to save time, besides Lin Xiuran, there was also a young forensic doctor from the city bureau who performed the autopsy together with him.Lin Xiuran was in charge of Dong Fang's body, and the other was in charge of Ma Aijing's.

The forensic doctor is called Wan Zong, nicknamed Duan Wu, a small forensic doctor with glasses. He has graduated from the forensic department for three years this year, and there are not enough forensic doctors in Nancheng. With his qualifications, he has already followed the case independently.Speaking of which, the nickname Duanwu has something to do with Lin Xiuran, because Zong’s pronunciation is the same as Zong, and Wan Zong’s nickname is Xiao Zongzi. Later, when he came here to report, he was afraid that everyone would not remember it, so he mentioned his nickname and said You can also call him that.

In those few years, tomb robbery novels were popular. Lin Xiuran frowned when he heard his nickname. Although it was said that those were feudal superstitions, but people thought that our appraisal center cheated on corpses when they called them. From now on, your nickname might as well be called Duanwu. .So this Dragon Boat Festival was called out in the city bureau, and it turned out to be more than his real name.

The dissection room was extremely quiet, and the temperature here was much lower than outside.The death time of the two corpses was about four hours. Rigidity generally appeared within 10 minutes to seven hours after death, and then gradually eased.Now the rigor of the corpse was at its most rigid, and it lay unnaturally on the dissecting table.

Duan Wu had just slipped over from his sleep, still a little dazed, observed the appearance of the corpse and said: "It doesn't seem to be too much trouble today, it should be poisoned to death."

Lin Xiuran reminded him: "Don't be careless, you have to test it before drawing a conclusion." Forensic medicine must not have the idea of ​​​​working. Sometimes, the more simple the case, the easier it is to miss some details.Duan Wu is very courageous, but some people are a bit sloppy. Fortunately, the previous case was simple and there were no major mistakes.

The two began to get busy, communicating with each other while observing. Lin Xiuran re-measured the body's temperature: "The time of death is consistent with the rectal temperature, between twelve o'clock and one o'clock in the morning." Calculated according to the current temperature, every hour, The body is about 1°C lower.Compared with Dong Fang, Ma Aijing's rectal temperature is slightly higher.

While communicating, the two filled in the various inspection forms on the form. This step is to check the corpse form, and all traces on the corpse must be checked.The two walked around the dissecting table, Duan Wu said: "There is no trauma outside the body, the deceased's pupils are constricted, the mucous membranes are congested, and the spots on the corpse are bright red, which are obvious signs of poisoning."

After Lin Xiuran checked the appearance of the corpse, he began to cut with the knife. The skin and flesh were neatly separated, and a capital Y was drawn on the corpse. There was a stronger smell of bitter almonds in the air. Beginning, gradually to the digestive glands.

"Muscles and blood are bright red. The digestive tract is edematous and congested...Because the deceased had vomited, the contents of the stomach were not too much, and there were black particles of chocolate." With Lin Xiuran's skillful movements, the stomach contents and heart blood were quickly extracted Completed, full of heart and blood, put into the test tube, waiting for the test.

The progress of the Dragon Boat Festival on that side was also very smooth, and the corpse was quickly disembowelled, and the internal organs were taken out and weighed.

Time passed quickly, and the two of them worked together for nearly two hours. The Dragon Boat Festival was finished first, and he put down the dissecting tools and said, "This side is finished, and it is basically confirmed that it is poisoned. If there is no problem, I am going to suture it here." gone."

"Wait a minute, I'll come over and take a look." Lin Xiuran put down his work, walked over, and looked at Ma Aijing's body.He is the person in charge of the identification center, and he has to sign all the inspection reports, and he is also responsible for the dead.

Lin Xiuran looked at the corpse for a few seconds, his expression became solemn, and he frowned deeply in thought. Now Lin Xiuran is a little sleep deprived and extremely tired. As soon as he closes his eyes, the girl's corpse tightly entangled with the quilt appears in front of his eyes. The image of being together, somehow lingering.It seems that he is hinting at something in the dark...

I don’t know if it was affected by the high-power refrigerator next door. The temperature here is much lower than outside. The internal organs of the two girls’ corpses on the dissecting table were taken out, and they lay there side by side. The skin was illuminated by the white shadowless lamp. A frightening light.

The funeral parlor in Nancheng City is located in the northern outskirts of the city. The building is very grand, but the land is sparsely populated, not to mention that in this dark night, except for the on-duty staff, there are only the two of them, and there are many more dead than living.I didn't feel it when I was working before, but this quietness made the courageous Duan Wu a little bit unbearable.He looked at the serious Lin Xiuran, a little guilty, and carefully compared the corpse in front of him, but still couldn't see the clue, and asked in a low voice, "Aren't these all typical characteristics of green gas poisoning?"

"This corpse is not right." Lin Xiuran didn't draw a conclusion quickly, but went to Dong Fang's corpse to check again, then he opened the dead man's eyelids and looked into the dead man's eyes for a moment.Then he let go of his hands before continuing, "There is nothing wrong with being poisoned, but this corpse is obviously different from mine. For example, poisoning will not cause blood spots on the eyelids and cheeks..."

As Lin Xiuran spoke, he stretched out his hand and pulled a white lamp over. Under the light, some bright red blood spots on the face of Ma Aijing's corpse could be clearly seen. These traces were not clear when she just died. , has become more and more obvious.

Duan Wu came over to observe, the red dots scattered on the face were very small, not easy to find without careful observation, as if all the capillaries on the face burst for some reason.Looking at it so closely, it was a bit weird, as if someone had sprinkled a handful of cinnabar on the face of the corpse.

"Also, she painted her nails to cover up the cyanosis of her fingers." Lin Xiuran pointed to the front of Ma Aijing's fingers, where the color was purple.He poured some chemicals on the cotton wool and wiped off Ma Aijing's remaining nail polish. The girl's fingertips were bruised and purple, and the color of her nails was abnormal, and the traces of cyanosis were more obvious.

"Others are..." Lin Xiuran pointed to some spots on the internal organs of the deceased.

With the emergence of clues one by one, a chilling truth gradually surfaced, Lin Xiuran felt his heart shrink leisurely, this murderer was too insane.

"Ta Diao's spot..." Now Duan Wu recognized it. Ta Diao's spot refers to some spotting bleeding under the mucous membrane, which is one of the characteristics of suffocation death. "So... the real cause of death is... suffocation?"

Lin Xiuran opened the mouth of the deceased and observed the teeth of the deceased. The neck of the teeth showed a pink color.This phenomenon has a romantic name, called rose teeth.

Seeing this, Lin Xiuran made a serious conclusion, "Yes, the victim was smothered to death by the quilt." Then he straightened up and added: "The poison had already started to develop when the deceased died, so some of the characteristic poisoning phenomena in the corpse , for example, the plaques are bright red, so you ignore the features of suffocation."

Because it was suffocated and at the end of poisoning, it did not have some characteristics of mechanical suffocation, such as hyoid bone fracture, so it was easy to be confused with death by poisoning.

This is the result of terrific thought. The two victims died together almost at the same time, but the cause of death was completely different.Perhaps something happened during the poisoning process, and the murderer couldn't even wait for Ma Aijing to die.But she must let her die as soon as possible, poisoning, suffocation, all of which are extremely painful, it is hard to imagine what kind of process this girl went through before she died.

"It's because I didn't look carefully." At this time, Duan Wu faced up to his mistake. The reason why he judged wrong was because the signs of poisoning in the corpse were too obvious. He had a subjective assumption when he came up, thinking that he must have been poisoned to death, so he He didn't consider other possibilities. Now that Lin Xiuran pointed it out, Duan Wu realized that he had almost made a big mistake, and broke out in fright. "Director Lin, does this cause of death have a big impact on the case?"

Lin Xiuran glanced at him: "Naturally, the dormitory has no trace of intrusion. In this way, the murderer is confined to the dormitory, and this murderer is too cruel." He said, looking at the lying on the bed. On the dissecting table were two disemboweled corpses, and two young girls with their eyes wide open, dying with regret.

At the scene, Ma Aijing's body was entangled with the quilt. At first they thought it was because the poisonous hair was more painful, so the victim grabbed the quilt tightly. Now that they think about it, the quilt should be the murder weapon. At that time, afraid that she would yell, someone directly straddled her body, suppressed him with both hands, covered her head with the quilt, and suffocated her to death in the quilt, which caused her to hold onto the quilt tightly , lethal cannot be separated.It was also this action when she was about to die that helped Lin Xiuran determine the real cause of her death, and further pinpointed the murderer, who was in the 108 dormitory.

At 05:30 in the morning, the criminal police continued to interrogate, Bai Xiaoxiao was sent away, and the person in front of Song Wen and Lu Siyu was replaced by Deng Jia.It was this girl who found Guo Wei lying at the door with poisonous hair. Now her face is still pale, and she seems to be still immersed in that nightmare.

Deng Jia was a year older than Bai Xiaoxiao, at first she just shook her head and said she didn't know, she said she was not familiar with the dormitory next door, halfway through the conversation, Lu Siyu went out and poured some hot water for her, Deng Jia gradually relaxed down.

"There are a total of [-] students in their civil engineering class, most of them are boys, only four of them are girls, Dong Fang is the richest and generous, Ma Aijing is the most beautiful, and was chosen as the department flower..."

"Do you know how Dong Fang treats Ma Aijing?"

"It's not good for her. I saw Dong Fang jokingly say that Ma Aijing is a sycophant, a little follower, picking up things she doesn't want, but I think Ma Aijing should have heard the truth in her heart." Go, she has a bit of a grudge."

"Do you know about Dong Fang's bullying of Guo Hua?"

Deng Jia hesitated for a moment, nodded and shook her head, and then said timidly: "Bai Xiaoxiao is familiar with Guo Wei, and I have a normal relationship with her."

Song Wen understood it, even if she knew it, ordinary girls like them didn't dare to care about it, if they saw it, they could just pretend they didn't see it.They asked Deng Jia a few more questions, and they basically said the same thing as Bai Xiaoxiao's description.

It was already getting bright outside, the sun poured in through the not-so-drawn curtains, the dark clouds dispersed, and the rain still did not fall in the end.

Song Wen and Lu Siyu glanced at each other, and when they were about to finish, he asked routinely: "We have almost covered what we want to know, do you have anything else to add?"

Deng Jia bit her lip, as if she had made a lot of determination, "Half a month ago, very late, at about 11:30 in the evening, I left my things in the study room, and I went to pick them up at night. From afar, I saw Ma Aijing coming in with a middle-aged man, that man seemed to be a professor from their civil engineering department..."

"Did you see clearly at that time?" Song Wenjia asked. According to Deng Jia's description, it was very late and far away, so it was easy to misread.

"It should be Ma Aijing..." Deng Jia recalled, "I recognize her umbrella. She has a very unique flower umbrella printed with Van Gogh's sunflowers, which is particularly conspicuous on rainy nights."

Song Wen nodded: "Thank you for providing clues, we will find out these things later." He sent Deng Jia out.

The inquiry on Fu Linjiang's side has also ended, and several criminal policemen gathered together to collect the information.

Song Wen briefly talked about their results here, then raised his head and asked Fu Linjiang, "How is your place? Is there any result?"

"We asked their head teacher and several teachers who taught the class, but they didn't know anything. Their head teacher became very emotional at first, saying that it was definitely not Guo Hua or Lin Wanwan. Her own students knew it by themselves. They are all good kids. When I asked her if Guo Hua was bullied and if she knew about it, she changed her mind and said that she didn't know or understand." Fu Linjiang sighed, "She is a 26-year-old female teacher who just graduated from a graduate school, and she herself Not much older than a student."

Song Wen nodded. He didn't expect to find more clues on the Internet. The age difference is like an insurmountable gap. One side is an adult who has entered the society, and the other side is still an adult on campus. child.

If a class in a university compares students to a flock of sheep, the teacher is like a shepherd dog. They only care about which sheep are left behind, but they are always slow and indifferent to the fighting among the flock.

Song Wen turned his head and asked Lu Siyu, "What do you think after finding this out?"

Lu Siyu was not on guard and was pointed again. He thought for a while and said, "The exact source of the poison and the person who poisoned him still have no idea. The relationship between the characters seems simple, but I always feel that something is not right."

Fu Linjiang interjected: "That's right, students from the Department of Civil Engineering, but not from the Department of Chemistry, how can they obtain such controlled highly toxic materials? Do they know students from the Department of Chemistry, so they can take out poisonous substances from the laboratory?"

Song Wendao: "Universities have all kinds of drug control methods. If you want to get poison out of them, it's hard not to leave traces. You can call down the monitoring later and ask the teachers here." In the past few similar cases in China, There have been cases where poisons have been removed from chemical laboratories, and after those cases, laboratories in universities and colleges around the world have tightened controls.

At the end of the conversation, Song Wen's cell phone rang. Seeing that it was Lin Xiuran's call, he raised his hand and pressed the answer button, "Hello, Lao Lin? How's the situation?"

After Song Wen answered for 2 minutes, he turned his head and said to others, "Part of the results of the autopsy came out. Dong Fang was poisoned to death, and Ma Aijing was smothered to death. The main ingredient in the poison is sodium green gas. , and a small amount of anesthetic was also found in their bodies."

The expression on Lu Siyu's face changed slightly, and his brows suddenly relaxed. It seemed that the doubts that had been bothering him had finally been confirmed, and then he lowered his head and said, "Then the suspects are Guo Hua and Lin Wanwan. between?"
