Since last Friday, on the morning of November 9th, Wu Weifan was taken to the cafeteria by Chen Xianwen and imprisoned, and on Monday the 12th, Wu Jun flew to the school to shout for dignitaries. It wasn't until the morning of the 17th that Tian Yuyi and Qiao Mang teamed up to deceive him away, who knew that he got out of the tiger's den and entered the wolf's den again. Wu Weifan was imprisoned by his stepmother for two more days, and on the 19th, he was about to come to an end, who knew that this would be the result.

On the operating table in the dissection room, Wu Weifan's body lay calmly on it. The bleeding from his wound had stopped. Zhang Lanshan and her assistant, as usual, wore dissecting surgical gowns, held dissecting tools, and stabbed the corpse again and again with expressionless faces. Jiang Chonglang was still standing beside him, quietly observing.

Zhang Lanshan calculated, Wu Weifan had a total of fourteen knife wounds. Three were fatal wounds, around the heart and neck, and the rest were scattered around the body. After testing, the time of death will definitely not be earlier than 8 o'clock today.

Zhang Lanshan pointed to several wounds on Wu Weifan's body and said: "Although there are three fatal wounds, what really killed him should be the knife wound on his neck." Because there is a life reaction in the wound, but not in the other two. ”

The so-called life reaction: because when a sharp weapon pierces the body of a living person, due to the pain, the body will shake to a certain extent, so it will leave some small wounds on the flesh near the wound, and when stabbing a person to death with a sharp weapon, because there is no intuition, the wound is relatively flat, which is the manifestation of no life reaction.

Immediately afterwards, Zhang Lanshan said: "Look at the fourteen knives on the deceased's body, their depth, strength, or piercing angle are different. For example, the knife on the left leg and the knife on the abdomen, the wounds have life reactions, both of which were caused by the deceased before his death. However, the depth of the former's strength is much greater than that of the latter, and for example, the wounds on the left thigh and calf can be analyzed through the angle of the piercing, and the murderer's posture holding the knife is also different: the former wound is sharp at the top and blunt at the bottom, indicating that the murderer is holding the knife with the blade facing upwards; The latter's wound is blunt at the top and sharp at the bottom, indicating that the murderer is holding a knife with the blade facing downward. There were also two wounds, apparently left with a knife, which should have been stabbed by a left-handed man. So there should be more than one murderer, and it is roughly estimated that there are at least five or more. ”

Five people killed one person, and there may be more than five people, and the number of murderers still shocked Jiang Chonglang. How brutal this scene is. The suspects who were just caught were investigated: Tian Yuyi was eating, drinking and having fun near his hometown, but was held down by the police; Xia Qiaona was at home before eight o'clock in the morning, and after meeting Qiao Mang at 9 o'clock, the two drove to the airport. Qiao Mang didn't have time to commit the crime, and besides, if he wanted to tear up the ticket, there was no need to bring so many people over. Therefore, their suspicions can be ruled out.

At the same time, the Traces Section identified blood-stained bed sheets and a large number of disorganized shoe prints at the scene. The blood-stained sheets had a small amount of plastic fibers on them. And after analyzing the shoe prints at the scene, it can be determined that the murderer is more than one person. At least 3 to 4 people. According to the size of the shoe print, the height and weight of these people can be reversed. It's just that to their surprise, based on the data provided for height and weight, an experienced veteran detective in the bureau judged that these murderers might all be ********.

At the same time, Han Yuchao found a blood-stained plastic sheet in the garbage heap in this shantytown. There were a lot of knives stabbed on it. It has been verified that almost all the wounds on the plastic sheet can be found on Wu Weifan's body, and the blood stains on it are Wu Weifan's after laboratory testing. Xue Ran and Shen Bin visited a department store wholesale market near this shantytown, and the owner inside confirmed that there was a group of people on the morning of the 19th, about 6 or 7. Came to him and bought a short knife. They all look like a bunch of high school students. At the same time, the owner of another shop also confirmed that the group bought a large sheet of plastic sheeting from him.

Through video surveillance, you can clearly see the height and size of these people, a total of 7 people. Through the camera, Jiang Chonglang saw the four boys around Chen Xianwen that day, and none of them fell.

The case can basically be closed, the police car is on the way to Yangcheng Y, Jiang Chonglang's heart can't help but become heavier and heavier, he thinks about his childhood, and he has also been rebellious and rebellious. But the price of the most blood paid is to fight in groups, but it has never been a life.

After arriving at Y Middle School, Chen Xianwen with a suitcase came up to him.

Chen Xianwen saw Jiang Chonglang and them coming, and said: "Captain Jiang, I am leaving the school today, I am alone, I don't want anyone to send me, leave quietly, I don't want my students to know, I hope you don't tell them these days." ”

Jiang Chonglang continued with his words: "Teacher Chen, although you think so. But there is no impermeable wall in this world, and if you just walk away like this now, I am afraid that your students will not be at ease for the rest of their lives, and you will not be able to feel at ease for the rest of your life. As he spoke, he asked the person behind him to take Chen Xianwen's suitcase back, and he walked towards the school with Chen Xianwen with a puzzled face.

At this time, it was almost noon to get out of school, and Jiang Chonglang led Chen Xianwen to the boys' dormitory quickly. Directly asked the dormitory manager Wang Boyan where he lived in which room, Chen Xianwen said 302.

The boys' dormitory is always mixed with all kinds of strange smells, and when he walked to the door of 302, Jiang Chonglang said to Chen Xianwen: "Were all the students in your class in the class yesterday morning?" ”

Chen Xianwen said: "Yesterday morning, the school organized an inspirational meeting, which was held in the lecture hall for almost two hours, and I was preparing for classes in the office at that time, so I didn't follow along. ”

Jiang Chonglang said: "Teacher Chen, don't leave yet, I'm afraid your students will give you a very big farewell gift." ”

When he walked into 302, he heard a swarm of flies "buzzing", and Jiang Chonglang found that in addition to these flies concentrated on the table, under the bed, eating dirty clothes and smelly socks, there were also some flies, which had been circling around outside a student's cabinet. Jiang Chonglang opened the cabinet, and sure enough, he found a knife inside. Although the top of the knife had been wiped clean, a closer look could still smell some blood.

Jiang Chonglang sent someone to take the knife back to the Traces Section of the Public Security Bureau for testing, saying that the results would come out soon. After Jiang Chonglang told Chen Xianwen that Wu Weifan was dead, and the murderer was a student in Chen Xianwen's class. Seeing that the students had finished school, Wang Boyan and a few boys walked into the dormitory.

As soon as Wang Boyan entered the dormitory, he saw Jiang Chonglang, and found that his cabinet had been opened by outsiders. understood what was going on, and without waiting for the two to ask, Wang Boyan said directly: "I know what you are doing here, Wu Weifan's grandson was killed by me." If he returns to our class, he will inevitably make trouble again, and his brother will definitely be retaliated by him. I already knew that my brother had already handed in his resignation letter, and we didn't want him to leave, so I slaughtered the grandson. I did it alone, and it had nothing to do with anyone else. Captain Jiang, don't be embarrassed, I'll just go with you. ”
