Criminal Investigation Notes

The entire dormitory building of Nancheng University has been remodeled the year before. Now there are four people in one dormitory. Under the bed is a computer desk and a cabinet. The upper bunk sleeps people. On the side of the dormitory, there is a small toilet where you can only use the toilet. Washing and washing, not taking a bath, Song Wen followed Lin Xiuran and walked in on his toes. The bedroom was already in chaos, with bedding and various books scattered on the ground.

On the south side of the bedroom, there are two young female corpses wearing only pajamas. One of them is curled up and shrank in pain in the corner. The girl is wearing a fan-like lace pajamas. Although her face is a bit hideous, she can see Get fair skin.

The other one was not far away from her. It appeared to be rolled down with the quilt. The female body was a girl with long curly hair. She was thin and had dark red nails on her hands, because of the extreme pain before her death. She and the quilt were almost twisted together, with both hands and feet embedded in the quilt. Now a dead body has formed, and a famous forensic doctor is trying to separate her from the quilt.

Both of these girls were just in their early twenties. They were originally at a good age in life, but now they died tragically in their dormitory one night.Even though Song Wen has been accustomed to seeing life and death in the past few years of work, he still can't help but feel helpless when he sees this scene.

The two obviously experienced a struggle before they died, their faces were hideous like ghosts, because they were poisoned, their lips were not normal, there was some vomit on the ground, and they also caused incontinence, giving the whole bedroom a pungent smell. .

Lin Xiuran has briefly checked the corpse. At this time, physical evidence was taking photos to collect fingerprints. In order not to interfere with their work, Lin Xiuran dragged Song Wen back to the corridor and introduced: "The identities of the two deceased have been confirmed. They are both from the Department of Civil Engineering. In the senior year of China, Dong Fang is curled up, and Ma Aijing is holding the quilt. It should be poisoned by a strong poison, and it takes no more than one and a half hours from the onset of the poison to death."

"Senior year, civil engineering, should I be preparing my graduation thesis, defending and looking for a job at this time?" Song Wen asked, "Is the cause of death determined?"

Lin Xiuran said: "They are acute poison poisoning. After the attack, they caused breathing difficulties and died of heart and lung failure. We just collected some samples and need further autopsy." After thinking about it, he added, "At present, other dormitories The student did not respond. It should be for the poisoning incident in this dormitory. The poison is suspected of being a blue gas."

"Where did the poison source come from?" Song Wen shook his gloves and put on them. "Isn't this kind of poison known to be faster and less painful?" The two girls were obviously tortured before they died.

"Maybe the dose is not large, it's only a small amount, but it is enough to kill." Lin Xiuran explained, "After the poisoning, the time and state of the attack are mainly related to the blood concentration..."

As the two of them were talking, a strong light suddenly shot from outside, cutting through the dark night, and piercing Song Wen's eyes. Lin Xiuran was also dazzled by the light, and turned his head away. Song Wen opened his five fingers to block his eyes. When I checked the corridor, I saw an Audi slowly stopping 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 wanted to ask which blindly leader drove this car, and still think this case is not enough?Then he saw Lu Siyu open the door and get out of the car...

The dark clouds in the sky have not yet dissipated, but the wind has disappeared. The air is still stuffy, and it feels like a rain will come at any time.In the girls' dormitory at two o'clock in the morning, the teacher began to comfort the students one after another, telling them to turn off the lights to sleep and not to go out.

Downstairs in the dormitory, Lu Siyu locked the 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, did you know that you have to be low-key when handling the case? So eye-opening? Are you planning to drive a Ferrari next time?"

At this time, Lu Siyu could not see the embarrassment of last night at all, nor could he see any lack of sleep. Under the action of large doses of painkillers, he was now at the most excited and awake moment.Lu Siyu didn't mention what happened last night, as if everything had been turned over. He played his role as an intern policeman.He walked closer and looked at Song Wen indifferently and seriously: "Team Song, you are dressed very well."

Song Wen rolled up his sleeves and said: "This is an accident." His tone was not as confident as he was in the past. He is usually vigorous and vigorous, most of the time stern. Being tough will make people forget his age. At that time, it reminds me that he was not much older than the students in these schools.

"It's nothing, it's pretty good, it looks very long." Lu Siyu looked at Song Wen while speaking. Under the light of the incandescent lamp, his white shirt and snow-white skin were used to light the board. I don't know it was him who dressed. The style of the shirt is still the style design of the shirt. The cuffs and collar buttons are unbuttoned. Under the shirt, a thin wrist is exposed, which is even more attractive.

Song Wen was in a daze for a while, he didn't expect anyone to wear a white shirt so clean and beautiful.

Lu Siyu walked a few steps closer and stood in front of Song Wen, stretched out his hand to help him trim the collar corner of his shirt, and whispered: "Song team, you can actually call me and let me bring it for you. There is a set of spare clothes in the trunk of my car, or you can change it in my car." After Lu Siyu finished speaking, remembering something, he whispered softly, "Change the coat and shoes. Otherwise, it's not very coordinated." After speaking, he stuffed the heavy car key into Song Wen's hand.

Song Wenla thanked him, hurriedly took the key and ran out.

Lu Siyu put on his gloves, took a pen and paper, and began to record. Xiaocheng was taking a picture inside. He nodded when he saw him. There was also a male physical evidence who also waved his hand to say hello.

There were four or five people standing in the small dormitory, and they had to be careful not to step on anything on the ground, which made people unable to move their feet.After remembering the time and location, Lu Siyu came to Dong Fang’s corpse. Due to struggle, under Dong Fang’s pajamas, he could see that corpses had formed on his body over time. Too the same, showing a bright red.Lu Siyu stretched out his fingers again and carefully looked through the gloves under the deceased’s eyes and the mucous membranes in his mouth. They were all in a state of fuchsia red hyperemia. He raised his head to look at Lin Xiuran and asked, "Cyan vapor?"

Lin Xiuran nodded: "Suspected, but further testing is needed." After this kind of poisoning, the body's oxygen utilization will be insufficient, and the oxygenated hemoglobin in the blood will increase, so the corpse spots will be different from the general situation and appear bright red. This is obvious One of the characteristics is also the basic common sense in forensic medicine.But for the sake of rigor, he did not make a decision now.

Lu Siyu looked at the time again and found that the time of death was about an hour or so, that is, one o'clock in the morning. If the poisoned dose is large, lightning coma or death will occur, and people will die within a few seconds. Rescue is too late.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, there is a process of attack. After the poison is taken, the latent time is about half. After more than an hour, there was a fifteen to forty minute poisoning process.

Lin Xiuran was on the side, watching Siyu Lu busy. This newcomer was not only a criminal policeman, but also a forensic doctor. His good grades and professionalism enabled him to cope with the work at hand well.

People say that medicine is an industry of Buddha's mind and ghosts, but Lin Xiuran feels that this Buddha's mind has dragged him down, preventing him from going beyond the world, seeing more cases, punishing more criminals, and helping more people. people.

Lin Xiuran has been working hard to become more professional, but he has been in the industry for nearly ten years, and after all the battles, he still can't be indifferent to death.He can tolerate more terrible corpses, more unpleasant smells, and has more exquisite technology, but whenever he faces victims, he can never overcome his compassion for these people. There is always kindness and sympathy in his heart. cause trouble.

Lin Xiuran feels that Lu Siyu is different from ordinary people. This newcomer has impressed him from the first time he came to the scene. Now the second cooperation is also the same. Lu Siyu has a different kind of "indifference" to life and corpses. , This is a commendatory description.Lin Xiuran felt that as a forensic doctor, he was indifferent and cold enough to restrain his humanity and enable him to devote himself to the case better.Only by not allowing the sympathy and fear of those human beings to influence oneself, can all truth be explored objectively.

Lu Siyu seemed indifferent to these victims, but he was fully committed. He was cold and ruthless, but he was also fearless. Any misery seemed to make him unmoved.

Now standing in the bedroom, Lu Siyu seems to be able to see everything the girls have experienced before.

At around eleven o'clock in the evening, the girls took the poison almost at the same time, but the dose was large or small. The lights in the bedroom were turned off at twelve o’clock, and they went to bed on time after washing. At first they just felt a little numbness in the mouth. She wanted to moisten her throat with saliva, but she started to salivate uncontrollably at the corners of her mouth. Then Dong Fang, who had taken the largest dose, started to vomit. She didn't have time to get off the bed, so she tilted her head and vomited on the pillow, so she left it on the pillowcase. There was a pool of vomit.

The girls who heard the sound got up one after another, but because of the silence of the night, they did not attract the attention of other bedrooms.The two girls with milder 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 turned his head and looked at the bed on the side. After Dong Fang, Ma Aijing also began to have a seizure. She was more violent and fell directly from the upper bed wrapped in a quilt. The vomiting did not relieve their symptoms. Headache, nausea, chest tightness, and difficulty breathing.At that time, the women who had studied chemistry should already know what had happened, but the onset of the poison was so rapid that they had no time to do other reactions, or did they deliberately didn't 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 quickly choked her and couldn't make a sound. She left some blood stains on the door of the next bedroom with her finger.

In the end, the fourth girl also started poisoning... But what was she doing before?What did you do after that?Lu Siyu frowned slightly and returned to the messy bedroom.

The girls were struggling, unable to call for help, irregular heartbeats, weakness in their limbs, pupils diminished, and then convulsions... Finally they entered a period of paralysis and went into a deep coma until they died.

This is the end of the hallway in the dormitory. With such a movement, no one was disturbed except for the 107 next to it.
