Criminal Investigation Notes

The whole dormitory building of Nancheng University was renovated the year before last. Now there are four people in one bedroom. Under the bed are computer tables and cabinets. The upper berth sleepers. On the side of the dormitory, there is a small bathroom, which can only go to the toilet and wash, but can't take a bath. Song Wen walks in with Lin xiuran on his toes. The bedroom is in chaos, with bedding and various books and articles Scattered on the ground.

In the south side of the bedroom, there are two young female corpses only wearing pajamas. One of them is curled up in a corner in pain. The girl is wearing a lace nightgown with light fans. Although her face is somewhat ferocious, it can be seen that her skin is fair.

The other one is not far away from her. It seems that she rolled down with a quilt. The female corpse is a girl with long curly hair. She is thin and has dark red fingernails on her hand. Because of the extreme pain before death, she and the quilt are almost twisted together. Both hands and feet are embedded in the quilt. Now it has formed a stiff body. A famous forensic medicine officer is trying to put her and the quilt separate.

The two girls were both in their early twenties. They were in their prime years of life, but now they died in their dormitories one night. Although Song Wen had been used to life and death in the past few years, he could not help but feel helpless when he saw such a scene.

Before their death, the two men obviously experienced a struggle. Their faces were ferocious and fierce. Due to poisoning, their lips were not normal. There were some vomit on the ground, which also caused incontinence, which made the whole bedroom have a pungent odor.

Lin xiuran's body has been simply checked. At this time, there are physical evidence taking photos to collect fingerprints. In order not to interfere with their work, Lin xiuran pulls Song Wen into the corridor and introduces: "the two dead people have been identified. They are senior students in civil engineering department. Dong Fang is curled up and Ma Aijing is holding a quilt. It should be a strong poison poisoning, from the onset to death within an hour and a half. "

"Senior, civil engineering, should be preparing graduation thesis, defense and looking for a job at this time?" Song Wen asked, "is the cause of death confirmed?"

Lin xiuran said: "they belong to acute poison poisoning. After the attack, they cause dyspnea and die of heart and lung failure. We have just collected some samples and need further autopsy." After thinking about it, he added, "at present, the students in other dormitories have not responded. It should be aimed at the poisoning incident in this dormitory. The poison is suspected to be green gasification."

"Where did the poison come from?" Song Wen shook off his gloves and put them on, "isn't this kind of poison famous for its fast speed and less pain?" The two girls were apparently tortured before they died.

"It's probably a small dose, but it's small enough to kill." Lin xiuran explained, "after poisoning, the onset time and state are mainly related to blood concentration..."

As they were talking, a strong light burst out of the dark night and stabbed Song Wen's eyes. Lin xiuran was also shaken by the light, and his head turned away. Song Wen opened his five fingers to block his eyes and went to the corridor to have a look. There was an Audi at the door of the dormitory building.

Song Wen suddenly remembered a sentence, there are two kinds of lights in the world, one is other lights, the other is Audi lights. I just want to ask which blind leader drove this car. I don't think this case is enough? Then he saw Lu Si Yu open the door and get out of the car

The dark clouds in the sky have not dispersed, but the wind has disappeared. The air is still stuffy. It feels like a rain will come at any time. In the girls' dormitory building at 2 a.m., teachers began to appease the students one after another, asking them to turn off the lights to sleep and not to go out.

In the dormitory downstairs, Luchi locked Audi, put the car key in his pocket, and walked in from the door of the building.

Song Wengang was dazzled by the car: "little ancestor, do you know you should keep a low profile in handling a case? How about this? Are you going to drive a Ferrari next time? "

At this time, Lu Si Yu can not see the confusion of last night, nor any lack of sleep. Under the effect of large dose of pain relief drugs, he is now the most excited and sober moment. Lu Si Yu didn't mention what happened last night, as if everything had been turned over. He played his role as a police trainee. He came to the front and looked at Song Wen calmly and seriously: "Song team, you are also quite eye-catching."

Song Wen rolled up his sleeve and said, "this is an accident." The tone was not full of confidence in the past. He was usually vigorous and vigorous. Most of the time, he was strict. If he was tough, people would forget his age. At this time, it reminds people that he was not much older than the students in these schools.

"It's nothing. It's good. It's long legs." Lu Siyu talks and looks at Song Wen. Under the illumination of incandescent lamp, his white shirt and snow-white skin become light plates for each other. I don't know whether it's the style of his clothes or the design of the shirt. The buttons on the cuffs and necklines are unbuttoned. Under the shirt, a thin wrist is revealed, which is even more attractive.

Song Wen was in a daze. He didn't expect that someone could wear a white shirt so clean and beautiful.

Lu Siyu stood in front of Song Wen a few steps closer, reached out to help him trim the collar corner of his jacket, and whispered, "Song team, in fact, you can call me and ask me to bring it for you. Fortunately, there is a spare set of clothes in the trunk of my car. Otherwise, you can change it in my car." After Lu Si Yu finished speaking, he thought of something and whispered, "change your coat and shoes, or it's not very harmonious." With that, he put the heavy car key in Song Wen's hand.Song Wen took the key and ran out.

Lu Siyu, wearing gloves and holding a pen and paper, begins to record. Xiaocheng is taking pictures inside. He nods when he sees him. There is also a male material evidence, and he waves his hand to say hello.

There are four or five people standing in the small bedroom, and they should pay attention not to step on the ground at any time. It is a bit too hard for people to move their feet. After remembering the time and place, Lu Siyu came to Dong Fang's body. Due to the struggle, under Dong Fang's pajamas, we can see that the body has formed with the passage of time, but the spot is not the same as the general one, showing a bright red color. Lu Si Yu stretched out his finger again and carefully looked through the glove at the dead man's eyes and the mucous membrane of his mouth. All of them were cherry red and congested. He looked up at Lin xiuran and asked, "blue gasification?"

Lin xiuran nodded: "suspected, need to further test to determine." This kind of poisoning will cause insufficient use of oxygen in the body and increase the oxygenated hemoglobin in the blood. Therefore, the necropsy will be different from the general situation and will be bright red. This is one of the obvious characteristics and is also the basic common sense in forensic medicine. However, in order to be strict, he did not make a decision now.

Lu Si Yu looked at the time again. The time of death was about an hour, that is, at 1:00 a.m. at night. If the dose of poisoning was large, lightning type coma or death would occur, and the person would die within seconds, even there was no time to rescue. But it seems that these girls are still normal when they are preparing to go to bed, so the poison may be taken before going to bed. Because the dose is not large, this has a process of attack. After taking the poison, the hidden time is about half an hour. After that, there is a 15 to 40 minute poisoning process.

Lin xiuran was on the side, watching Lu Si Yu busy. The new man was not only a criminal policeman, but also like a forensic doctor. His good grades and professional quality enabled him to deal with the work in front of him at the scene.

People say that forensic medicine is a kind of business of Buddha's heart and ghost hand, but Lin xiuran feels that this piece of Buddhist heart is a drag on him, making him unable to escape from the world, see more cases, punish more criminals and help more people.

Lin xiuran has been working hard to make himself more professional, but he has been in the business for nearly ten years and experienced many battles, but he still can't be indifferent to death. He can tolerate more terrible bodies, smell worse and have more exquisite skills. However, when facing the victims, he can never overcome his pity for these people. There is always kindness and sympathy in his heart.

Lin xiuran thinks that Lushi language is different from ordinary people. This new man has made him look at the scene from the first time he came to the scene, and now the second cooperation is even more so. Lushi language has a kind of "indifference" to life and corpses, which is a kind of commendatory description. Lin xiuran felt that as a forensic medicine, he was cold enough and restrained human nature, so that he could better devote himself to the case. If we do not let the sympathy and fear of human beings affect us, we can explore all the truth more objectively.

Lu Si Yu seems to be indifferent to these victims, but he is totally devoted. He is cold and merciless, but he is not afraid. Any desolation and tragedy seems to keep him unmoved.

Now standing in the bedroom, Lusi seems to be able to see what the girls have been through before.

At about 11 o'clock in the evening, the girls took the poison almost at the same time, but the dosage was large or small. The lights were turned off at 12 o'clock in the bedroom. They went to bed on time after washing and gargling. At first, they just felt a little numb in their mouth. They tried to moisten their throat with saliva, but they began to salivate uncontrollably at the corners of their mouths. Then Dong Fang, who took the largest dose, began to salivate When she vomited, she didn't have time to get out of bed, so she vomited on the pillow, leaving a pool of vomit on the pillow case.

The girls who heard the sound got up one after another, but in the dead of night, they did not attract the attention of other bedrooms. The two girls with mild poisoning even came to investigate Dong Fang's condition, but at that time Why didn't they call for help and call the police in time?

Lu Siyu turns his head and looks at the bed beside him. After Dong Fang, Ma Aijing also begins to attack. She falls down from the upper bunk with a quilt. Vomiting does not relieve their symptoms. At the same time, she has headache, nausea, chest tightness and dyspnea. At that time, they should have known what had happened to them after studying chemistry, but the rapid attack of poison made them have no time to do other reactions, or did they deliberately not do other reactions?

At this time, a girl ran out and came to the corridor. At that time, she had already begun to attack. The poison soon suffocated her and could not make any sound. She left some blood stains on the door of the next bedroom with her fingers.

Finally, the fourth girl began to poison But what was she doing before? What did you do after that? Lu Si language slightly frowned, and returned to the messy bedroom.

The girls are struggling, unable to call for help, arrhythmia, limb weakness, pupil narrowing, and then convulsion Finally, they entered a period of paralysis, deep coma and death.

This is the end of the corridor in the dormitory. Except for 107 nearby, no one else was disturbed.
