Criminal Investigation Notes

At four o'clock in the morning, Lin xiuran, who carried the corpse back to the funeral home, had already started work. Two corpses were placed on two stainless steel anatomical tables waiting for dissection. There are no windows and no shadow lights in the whole dissecting room, and two super strong ventilation systems are specially installed.

The forensic work in Nancheng is ahead of other cities. There is a modern autopsy room in the Municipal Bureau, which is divided into three parts: standardized autopsy room, monitoring and consultation room and corpse storage room. It is mainly used for the dissection of some difficult corpses. However, since it is difficult to transport the corpses between the funeral parlor and the Municipal Bureau, the cause of death is relatively determined and waiting for burial The body will be disposed of in the autopsy room of the funeral home.

As there were two dead people, in order to save time, in addition to Lin xiuran, a young forensic doctor from the Municipal Bureau also dissected with him. Lin xiuran is in charge of Dong Fang's body, and another is in charge of Ma Aijing's.

The forensic medicine named Wan brown, nicknamed the Dragon Boat Festival, is a small forensic with glasses. This year, the forensic medicine department graduated three years ago. The number of forensic doctors in Nancheng is not enough. His qualifications have long been independent with the case. Speaking of the Dragon Boat Festival, the nickname also has something to do with Lin xiuran, because the sound of Brown is the same as zongzi, and wanbrown's nickname is xiaozongzi. Later, when he came here to report, he was afraid that it would not be easy for everyone to remember. He mentioned his nickname and said that he could be called that way.

In those years, tomb robbing novels were very popular. Lin xiuran frowned when he heard his nickname. Although he said that those were feudal superstitions, others thought that our appraisal center had cheated corpses. In the future, you might as well call it Dragon Boat Festival. So the Dragon Boat Festival was opened in the City Council, and later it was more than his original name.

The anatomy room is very quiet. The temperature here is much lower than that outside. The death time of the two bodies was about four hours. The stiffness usually appeared within 10 minutes to 7 hours after death, and then gradually eased. Now the corpse's rigidity is the most rigid time, lying on the autopsy platform unnaturally.

The Dragon Boat Festival was just lifted from my sleep and was still a little dazed. After observing the appearance of the corpse, he said: "today, it seems that there is no too much trouble. It should be poisoned to death."

Lin xiuran said to him, "don't be careless. You should test it before you reach a conclusion." Do forensic medicine, but do not have the idea of living, sometimes, the more simple the case, the easier it is to miss some details. The Dragon Boat Festival is very bold, but some people are a little careless. Fortunately, the previous case is simple, and there is no big mistake.

Two people began to work, while observing and communicating, Lin xiuran retested the temperature of the body: "the time of death is consistent with the anal temperature, between 12:00 and 1:00 in the morning." According to the present temperature calculation, every hour, the corpse is reduced by about 1 ℃. Compared with Dong Fang, Ma Aijing's Anal temperature was slightly higher.

While communicating with each other, they fill in the forms of various examinations. This step is to check the corpse form. All traces on the corpse must be checked. Two people walked around the dissection table for a circle, and the Dragon Boat Festival said: "there is no external trauma. The pupil of the dead person has shrunk, the mucous membrane is congested, and the corpse spot is bright red, which is a very obvious poisoning feature."

After examining the body's appearance, Lin xiuran began to cut the body. As the knife went on, the flesh was neatly separated, and a capital Y character was drawn on the body. There was a stronger bitter almond smell in the air. The examination started from the top and gradually reached the digestive gland.

"Muscles, blood are bright red. Gastrointestinal edema, congestion Because the deceased vomited, there was not much in the stomach, and there were dark particles of chocolate With Lin xiuran's skillful movements, the stomach contents and heart blood were quickly extracted, and the heart blood was full, and put into the test tube, waiting for the test.

That side of the Dragon Boat Festival is also very smooth, soon the body was rifled, viscera taken out to weigh.

Time passed quickly, and the two people were busy working for nearly two hours. On the contrary, the Dragon Boat Festival was completed first. They put down the anatomical tools and said, "this is done. It can be determined that it is poisoning. If there is no problem, I am going to sew it up here."

"Wait, I'll come and have a look." Lin xiuran put down his work and came to see Ma Aijing's body. He is the person in charge of the identification center. He has to sign all the test reports and be responsible for the dead.

Lin xiuran looked at the corpse for a few seconds. His expression became dignified and he frowned deeply. Now Lin xiuran was a little sleepless and very tired. As long as he closed his eyes, he saw the picture of the girl's body tightly entangled with the quilt. Somehow, he couldn't shake it. As if, in the dark, he implied something

I don't know if it is affected by the high-power cold storage next door. The temperature here is much lower than that outside. The viscera of the girl corpses on the two autopsy tables were taken out and lying side by side. The skin was illuminated by the white shadowless lamp, which gave out a ghostly light.

The funeral parlor in the southern city is located in the northern suburb of the city. It is very spacious and sparsely populated, not to mention in the dark night, except for the staff on duty, there are only two of them. The dead are much more than the living. Before the work did not feel that this quiet, let the courage of the Dragon Boat Festival also some can not stand. Looking at the serious Lin xiuran, he felt a little guilty. After carefully comparing the corpse in front of him, he still couldn't see the clue. He whispered, "isn't this all the typical characteristics of green gasification poisoning?"

"This body is not quite right." Lin xiuran didn't make a quick conclusion. Instead, he went to Dong Fang's body and looked at it again. Then he broke off the eyelids of the dead and looked at the dead's eyes for a moment. Then he let go of his hands, then opened his mouth and continued, "there is nothing wrong with poisoning, but this corpse is obviously slightly different from mine. For example, poisoning will not cause blood spots on eyelids and cheeks..."Lin xiuran spoke and reached for a white lamp. Under the illumination of the light, we could see some bright red blood spots on Ma Aijing's face. These traces were not clear when she just died. As time went on, they became more and more obvious.

Dragon Boat Festival came to observe, the red dot scattered in the face is very small, not easy to find, like the face of all the capillaries because of what reason burst open. So close, it's a little weird, like someone sprinkled a handful of cinnabar on the face of the corpse.

"And she painted her nails to cover up the cyanosis of her fingers." Lin xiuran points to the front of Ma Ai Jing's finger, where the color is purple. He poured some chemicals on the cotton wool, rubbed Ma Aijing's remaining nail polish, maiden's fingertips were blue and purple, and the color of his nails was abnormal. The traces of cyanosis were more obvious.

"The others are..." Lin xiuran pointed to some spots on the internal organs of the dead.

With the emergence of a clue, a chilling truth gradually surfaced. Lin xiuran felt that his heart was relaxed. The murderer was too insane.

"Ta Diao Shi ban..." At this time, the Dragon Boat Festival recognized that TA Diao's spot refers to some spot bleeding under the mucosa, which is one of the characteristics of suffocation death, "so The real cause of death is Suffocation? "

Lin xiuran opened the mouth of the dead and observed the teeth of the dead, showing a pink color at the neck of the teeth. This phenomenon has a romantic name called Rose teeth.

See here, Lin xiuran looks dignified ground to conclude, "yes, this victim, is suffocated by quilt." Then he straightened up and added, "the poisoning started at the time of death, so some of the characteristics of the body, such as the bright red of the spots, are ignored by you."

Because it is suffocating and at the end of poisoning, there is no mechanical asphyxia characteristics, such as hyoid bone fracture, easy to be confused with poisoning death.

This is a result of careful thinking and extreme fear. The two victims died together almost at the same time, but the cause of death was completely different. Maybe something happened in the process of poisoning. The murderer couldn't wait for Ma Aijing to die. But she had to let her die as soon as possible, poisoned and suffocated, which was extremely painful. It was hard to imagine what kind of process the girl went through before she died.

"I didn't look carefully." At that time, the Dragon Boat Festival faced up to his own mistakes. The reason why he made a wrong judgment was that the corpse was poisoned. He had a subjective assumption that he must have died of poisoning. He did not consider other possibilities. Now he was pointed out by Lin xiuran, and he realized that he had almost made a big mistake. He was scared out of sweat. "Director Lin, this is the cause of death Say, does it matter? "

Lin xiuran looked at him: "naturally very big, there is no sign of breaking into the dormitory, so that the murderer was confined to the dormitory, and the murderer, too cruel." As he spoke, he looked at the two disembodied corpses lying on the autopsy table. The eyes of the two girls were wide open, and they were still dying.

At the scene, Ma Aijing's body was entangled with the quilt. At first, they thought it was because the poison was more painful, so the victim grasped the quilt. Now they think that the quilt should be the murderer's weapon. When the murderer was poisoned, he was afraid of her shouting. Someone directly sat on her body and suppressed him with both hands. The quilt covered her head and made her live Live suffocated in the quilt, which led to her has been clinging to the quilt, death can not be separated. It was her act on the verge of death that helped Lin xiuran determine the real cause of her death and further targeted the killer, who was in the 108 bedroom.

at 5:30 a.m., the interrogation of the criminal police continued. Bai Xiaoxiao was sent away, and the person in front of Song Wen and Lu Si Yu was replaced by Deng Jia. It was this girl who found Guo Zhen who was poisoned at the door. Now her face is still pale and seems to be immersed in the nightmare.

Deng Jia is one year older than Bai Xiaoxiao. At the beginning, she just shakes her head and says she doesn't know. She says that she is not familiar with the dormitory next door. After half of the conversation, Lu Siyu goes out and pours some hot water for her. Deng Jia gradually relaxes.

"There are 30 students in their civil engineering class, most of them are boys, only four of them are girls. Dong Fang is the richest and most generous, while Ma Aijing is the best looking and selected as the Department flower..."

"Do you know what Dong Fang did to Ma Aijing

"It's not good for her. I saw once that Dong Fang said that Ma Aijing was a flatterer and a little Valet, picking up things she didn't want. But I think Ma Aijing should have heard her heart go, and she had a bit of resentment."

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

Deng Jia hesitated for a moment, nodded and shook his head, and then timidly said: "Bai Xiaoxiao and Guo Zhen are familiar with some, I have a general relationship with her."

Song Wen understood, even if they know, they are ordinary girls also dare not tube, see can only be regarded as not to see. They asked Deng Jia a few more questions, which were basically the same as Bai Xiaoxiao's description.

It was almost light outside. The sun poured in through the poorly drawn curtains, and the dark clouds dispersed. The rain did not come down in the end.Song Wen and Lu Siyu looked at each other and were ready to finish. He routinely asked, "we have almost everything we want to know. Do you have anything else to add?"

Deng Jia bit her lip and seemed to have made up her mind. "Half a month ago, very late, at about 11:30 p.m., I left my things in the study room and went to pick them up at night. I saw Ma Aijing coming in from the outside with a middle-aged man, who seemed to be a professor in their civil engineering department..."

"Did you see it then?" Song Wen added a question. According to Deng Jia's description, it was very late and far away, and it was easy to misinterpret it.

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

Song Wen nodded: "thank you for the clues. We will find out these things later." He sent Deng Jia out.

Fu Linjiang's inquiry has also ended, several criminal police came together to gather information.

Song Wen briefly described their results here and raised his head to ask Fu Linjiang, "how are you doing there? Is there any result? "

"We asked their teacher in charge of the class, as well as several teachers who taught the class. They were all asked but did not know. Their head teacher began to be very excited, saying that it was definitely not Guo Zhen or Lin wanwan. Her own students knew that they were good children. When I asked her if Guo Zhen had been bullied and if she knew about it, she changed her mind and said she didn't know Fu Linjiang sighed, "she is a 26 year old female teacher who has just graduated from graduate school, and she is not much older than her students."

Song Wen nodded. He didn't expect to find more clues there. The gap between the ages of a couple of years is like an insurmountable gap. On one hand, there are adults who have stepped into society, and on the other hand, they are children on campus.

If the class in the university compares the students to sheep, the teacher is like a shepherd dog. They only care what sheep have fallen out of the team, but they are always slow and indifferent to the fighting among the sheep.

Song Wen turned his head and asked Lu Si Yu, "what do you think about this?"

Lu Si Yu was not on guard and was ordered again. After thinking about it, he wanted to open his mouth: "the exact source of the poison and the person who poisoned it still has no clue. The relationship between the characters seems simple, but there is always something wrong. "

Fu Linjiang interjected: "yes, students from the civil engineering department, but not from the chemistry department, how can they get such highly toxic materials? Do they know students in chemistry department, and they can take poison out of the laboratory? "

Song Wen said: "there are all kinds of drug control methods in universities. If you want to take out poisons from them, it's very difficult to leave traces. Later, you can transfer the monitoring and ask the teachers here." In the past few similar cases in China, there were cases in which poisons were taken from chemical laboratories. After those cases, laboratories in Colleges and universities all over the country strengthened control.

The words are chatting here, Song Wen's mobile phone rings, he saw Lin xiuran's call, raised his hand to answer, "Hello, Lao Lin? What's the situation? "

After listening for two minutes, Song Wen turned to other humanitarians and said, "some of the autopsy results come out. Dong Fang was poisoned to death. Yes, Ma Aijing was suffocated. The main component of the poison is sodium cyanate, and a small amount of anesthetic has been found in their bodies

The expression on Lu Si Yu's face changed slightly, and his eyebrows suddenly expanded. It seemed that the suspicion that had been bothering him was finally confirmed. Then he bowed his head and said, "so, is this suspect between Guo Gu and Lin wanwan?"
