This is a right arm, except for the fracture, there are no other wounds on the arm. From the fracture, the tools used are the same, that is to say, it is still the same hand saw. After Xu Yiman checked the DNA, he was even more certain that the two limbs belonged to the same person.

Jiang He carefully observed the palm of his hand. He found a thicker callus on the first knuckle of his middle finger. The callus will gradually become smaller or even disappear with the loss of time, but the callus on the **** is still very obvious. This kind of callus is unique to the student party, mainly because it is too much to write with a pen. .

Seeing this, Jiang He said, "I have a 70% probability that the deceased person should be a high school student. Compared with college students, high school students use a pen refill every five days on average. In addition, Except for the callus here, the rest of the fingers are not, so it is certain that he will not be a learner of painting or design."

Shao Lao said: "That is to say, a high school student who is about eighteen years old, so this student is about to graduate."

The body of an 18-year-old high school student was cut into several pieces that cannot be determined at present, and was placed in various objects and thrown. And these limbs may be scattered in all corners of Shangxi City, and it is really troublesome to find them.

That rainy night, the murderer threw the body of the deceased away piece by piece, no one knew.

Plush toys also appeared in front of everyone.

Several people carefully observed the plush toy. At this moment, there were still some traces of soil on the plush toy. It seemed that it was stained in the garden of Xingfu Community. The line was torn on the stomach of the plush bear. Jiang He went to observe, this thread is also the thread used to sew the ball, and the manual work is also not very good, the stitches are messy.

"Football, plush toys." Shao Lao said: "The murderer must be young!"

Jiang He shook his head, expressing that he did not understand.

Shao Lao opened his mouth and said: "I still say that, any choice everyone thinks is arbitrary, in fact, the subconscious has already made a choice for you, if the subconscious can't make a choice for you, then you have eight to nine It's hard to choose..."

"I was also walking on the road. When I saw a looming red paper, most adults would think that they might have found money, but if it was a child, the answer would be much more." Shao Lao's words were very profound: "And people's cognition can't go beyond their own knowledge. It's like a child who has never seen a train. If you take him to a car, his first reaction is definitely a car instead of a train."

Seeing that Jiang He and Xu Yiman were both a little ignorant, Shao Lao had to say: "I won't explain the principle to you. In short, he must be under twenty-five years old, and the deceased was a student, so the murderer …”

Although this sentence is not spoken, the hint is already obvious.

"Is it such a big hatred?" Xu Yiman couldn't help but say: "After killing people, it is not possible for ordinary people to calmly divide the body and throw it away."

"Vendetta?" Shao Lao murmured to himself.

"Someone came to recognize the body!" Captain Li's voice came from outside.

"Bring it in!" Shao Lao responded.

After a while, seven or eight people came in. These people were men, women, young and old, and they were all dressed in different industries. The leader was a dark-skinned man in his forties. When he saw a few people, he was a little cowardly: "Here, is this the place to recognize corpses?"

Xu Yiman nodded, looked at the middle-aged man, turned his head to take the head, and halfway through, Xu Yiman turned his head and said, "I really don't want this to be your child, but I also hope that you can have Prepared mind."

Saying that, Xu Yiman took the head over. The moment he saw the head, a howling sound came out. Seeing that a middle-aged woman in the crowd gasped and fell to the ground instantly, the scene was momentary. Chaos. Everyone hurried to help, but found that the woman was breathing more and less, and it was about to die.

Jiang He said, "Xu Yiman, aren't you a surgeon before? Go and see what's wrong."

But after hearing Jiang He's words, Xu Yiman stepped back secretly, without any intention to lend a helping hand.

Shao Lao obviously noticed this, and he was a little surprised.

At this moment, Xu Yiman's eyes were fixed on the middle-aged woman on the ground. Her forehead was sweating, her chest was rising and falling rapidly, and the blood vessels on her face were even pierced by the force. It was highlighted, her breathing accelerated significantly, her hands clenched tightly into fists.

Jiang He couldn't equate the middle-aged woman's fainting with Xu Yiman's behavior, because there was no way to combine the two pieces of information. He didn't understand what happened to Xu Yiman: "Xu Yiman..."

However, Elder Shao held Jiang He back. Shao Lao could see Xu Yiman's mood at the moment from Xu Yiman's subtle movements - fear, these are the movements and expressions that people only have when they are afraid.

Xu Yiman held a dead head without the slightest fear, but when he saw the middle-aged woman collapsed in front of him, he was so scared. Shao Lao knew that there must be a story behind it.

"Where are the other forensic doctors in the bureau!" Shao Lao said.

Hearing the commotion, the criminal police from outside also rushed in. Naturally, there were also forensic doctors in the bureau. Several forensic doctors immediately began to examine the condition of the middle-aged women, and they carried the women away after a while. go out.

Those people also helped out, and there were only three people in the autopsy room.

Shao Lao gently patted Xu Yiman's shoulder.

Jiang He said, "I don't understand what you're doing. You're the doctor closest to her. I'm 100%..."

Shao Lao gently blocked Jiang He's mouth: "When I was young, like you, I always wanted to understand everything in the world, and I didn't care if it would hurt a person. But then I gradually understood, Sometimes the truth brings only pain, and this kind of irrelevant truth, in fact, there is no need to know at all."

Jiang He couldn't understand what Elder Shao was saying, but he still kept his mouth shut.

Xu Yiman also slowly came over, Shao Lao did not ask Xu Yiman anything, but looked outside.

And a few minutes later, the woman woke up leisurely, and Shao Lao understood that he had found the right person.

In order to fear that the corpse would cause another injury to the women, there were only a few men in the autopsy room at the moment.

"You know this head?" Jiang He asked.

The middle-aged man said, "Why, why only one head."

Jiang He shrugged, "So far we have only found a human head and right arm."

The man's hands trembled, and he tried to speak several times but failed to speak. Finally, a young man in his twenties next to him revealed the identity of the deceased:

The deceased's name was Song You. He was a senior in the No. 4 Middle School in Anxiang District, Shangxi City. To be precise, Song You had already graduated. After the summer vacation, he would go to another city for university. But who would have thought that, Just two-thirds of the way through the summer vacation, Song You was brutally murdered.

Song You's parents were honest farmers who were usually farmers in the countryside. They were kind to others and never had enemies.

Song You left home on the afternoon of August 8th, saying that he was going to the city to find his classmates to play with. Song You's parents didn't care. Summer was the busy time for farming. Song You's parents didn't take care of him since he was a child. When the child was older, he became more relaxed, and the child was a good candidate. Although he didn't get into any major university, at least he didn't have to work and farm with him in the future.

For the next four days, there was no news from Song You. Before, Song You would also go to the city to find classmates, and go home after playing for two days at most, but this time there was no news after a few days. Three days later, Song You's family called Song You. The phone was turned off, and the neighbors sent QQ, WeChat, etc., but there was no response.

So Song You's family became anxious and called the police today.

The technical section of the Criminal Police Team has been comparing the body information, and it happened to receive a missing person. The information was roughly the same, so he asked him to identify the body, and it turned out to be Song You.

According to the information provided by several people, Song You's parents have absolutely no enemies, and they said that Song You usually doesn't talk much at home. He is a child who is as honest as his parents. He is usually not seen bullying others. Who could he have a grudge against himself?

However, Jiang He never really believed what was said from people's mouths. He only believed what he saw with his own eyes. Because Jiang He never had any expressions when he lied, he thought witnesses were the most unconvincing.

Jiang He once compiled all the cases he knew, and then came up with a set of benchmarks through probabilistic analysis.

Among the murder cases Jiang He learned about, 50% of them were dismembered because they were afraid that the police would find the body, and they were dismembered for convenience. Thirty percent is because the murderer and the victim have hatred, and death alone cannot express his hatred. Eighteen percent of the people are because of fear. After dismembering the corpse, it is not a whole, but only pieces of meat, which can reduce the fear in their hearts.

Another 2% believe that killing and dismembering is an art. They will peel off human skins to make furniture, carve the human body as a material, and cut the human body into thousands of pieces. In the eyes of these people, there is no difference between murder and painting, music and art, but another kind of beauty.

At this moment, Jiang He still has no way to determine the motive of the murderer in this case, because with so many probabilities, it seems that it can be explained in any way. The current information is still too little, Jiang He needs more information to deduce some clues.

After learning about the situation, Mr. Shao said: "Find the last person who saw Song You. Since he came out to find a classmate, this classmate must be found. It's summer vacation and the school hasn't started yet. Captain Li, immediately contact Anxiang District. No. 4 Middle School, find Song You's classmates and investigate who Song You was looking for four days ago."

After speaking, Lao Shao comforted: "I can't say anything to appease everyone's grief, but I promise that this case will be investigated clearly."

At this time, Song You's father suddenly knelt in front of Lao Shao. He burst into tears and spoke in a strong local accent: "I beg you to catch the murderer, my son died so tragically..."
