"This human head has given us too few clues. At present, I haven't formed a high-probability clue provided by this human head in my brain." Jiang He looked at Lao Shao and said seriously.

Shao Lao shook his head: "Actually, you can see it, but you didn't use it in the reasoning. You can also see that this football is bigger than the footballs used in the competition on the market, which is actually a good reasoning. , because if it is really an ordinary football on the field, it is impossible to put the head in, so he bought a larger football."

Jiang He nodded and said earnestly, "Yes, I can see that. According to my experience, I have a 100% probability that this is a No. 7 football."

"You watch a football match?" Shao Lao looked at Jiang He.

Jiang He shook his head: "Before, my aunt loved to watch football. She told me a lot about football, so I kept it all in my head. The football model goes from the beginning to seven, and as the number gets bigger, The bigger the diameter of the football, it is the largest size of the football, and size 5 is the ball used in adult games.”

Shao Lao nodded and said, "So we have a clue now, this person is a football fan."

Jiang He shook his head, "I don't understand."

Shao Lao explained: "If you think about it, very few people know that football is divided into these models. Most people see football as a No. 5 football, and you rarely say that you want a No. 7 when you buy a football. Those who can make this request must have a good understanding of football. And since the No. 7 football is about the same size as basketball, and he doesn’t choose basketball, it shows that this person likes football far more than basketball.”

"I bought a No. 7 football on purpose." Shao Lao said: "The whole city is looking for such a person."

"Understood." Captain Li sent someone to arrange again.

Jiang He, however, shook his head: "I don't agree with the analysis of perceptual psychology from rational information. Information should deduce objective reality, not lead to a person's psychology. Human psychology is the most complex, and there is no can figure it out.”

Shao Lao said: "In that case, do you want to gamble with me?"

"What are you betting on?" Jiang He asked.

"Just bet whether the murderer is a football fan." Shao Lao said.

"Bet." Jiang He did not hesitate.

"That is, after the case is over, please eat watermelon." Shao Lao said.

Jiang He nodded, "Okay. But if you pass a football and say the murderer is a football fan, I have a 70% probability that you don't have enough information to support this, so there is a high possibility of failure. ."

Shao Lao shook his head: "It seems that you like to speak with data and probability, but you should understand that when people do any action, it is the action after the order is given in their heart or subconsciously, you think it is casual Actions are actually subconsciously controlling you, as long as you can realize the psychology of the characters behind all the actions in this world, you will find that this is not metaphysics, but real science.”

Xu Yiman listened to the two of them clearly, and she interrupted their conversation: "When you were observing and discussing just now, I carefully dissected this head. According to the previous observation, I found that in the After washing the blood on the head, the face of this head was swollen and swelled, and the face was cyanotic. You can see the corpse stains, the corpse stains are purple-red, so I cut open the deceased's skull and determined that the deceased died of suffocation. "

"Asphyxiation." Jiang He muttered to himself.

"That's right." Xu Yiman said: "Death by suffocation, I will let people test the blood collected so far to see if the blood contains poisons or drugs. So until there is no more information, there is no Until I find the rest of the limbs, I can't tell if it's mechanical or non-mechanical suffocation."

The two nodded.

Xu Yiman added: "Because there is only one head, after clearing the congestion in the eyes, I can see from the degree of corneal turbidity that the cornea has become completely turbid at this moment, and the pupils cannot be seen, so I injected atropine into the eye chamber. , the reaction is no longer positive. And the masseter, neck muscle stiffness has completely disappeared, that is to say, the corpse should have died for more than seventy-two hours. That is to say, it has been about three days and three nights. "

Jiang He estimated the time. It was now August 12th, and three days ago, August 9th, between 3 and 3 o'clock in the afternoon.

It's been a day and a night since the children saw football.

If we calculate from the time, the murderer is likely to be a resident of any district in Shangxi City for such a long time, and he can throw the bodies everywhere in one day and one night. This person can sew the head into the football to throw the body, so I am afraid that the rest of the limbs are also hidden.

"No one came to claim it?" Shao Lao looked at the head and asked Captain Li next to him: "Judging from the appearance, the deceased was not very old, he should have been a high school or a college student. Are you sure you haven't received any reports of disappearance in this area? "

"No." Captain Li said, "We also posted the photo, but no one came to claim it."

Shao Lao nodded and said nothing.

"Looking at the age of the bones, it should be about eighteen years old." Xu Yiman added.

"Go to various schools with the photos." Mr. Shao said, "This person is probably a student in eight to nine out of ten."

Just when Shao Lao finished saying this, he saw the funeral home hurriedly walk into a criminal policeman: "The body has been found."

"Have you found the rest of the limbs?" Shao Lao asked, "Where are they?"

Only then did the criminal police tell the ins and outs of the matter:

August 12, around ten in the morning.

In the Garden of Happiness Community in Zhongshan District, Shangxi City, many elderly people are walking and exercising in the garden. Aunt Li takes her little granddaughter ~ Tongtong to the garden to play. On the way, Aunt Li met a few acquaintances, so she let Tongtong play while she chatted with her acquaintances. Tongtong ran around alone and found a stuffed toy in the weeds in the distance.

This is a medium-sized plush toy with a height of about fifty or sixty centimeters, and it looks like a cute bear. Tongtong couldn't put it down and kept playing with it. About an hour later, Aunt Li took Tongtong home, and Tongtong also brought the plush toy home.

Aunt Li went home to cook, and she didn't care about Tongtong.

After Tongtong's parents came home, they opened the door and smelled a stench. This is an indescribable odor, as if something rancid in the house, sour and stinky, and it comes in bursts, sometimes it can be smelled, sometimes it can't be smelled.

They wondered where the smell came from, until Tongtong ran over with a bear-sized stuffed toy. Only then did Tongtong's parents know the source of the odor, but they didn't buy this stuffed toy for Tongtong.

Only then did Tongtong say that he picked it up by himself. Tongtong's parents asked Tongtong to throw the teddy bear away, and Tongtong cried.

Seeing this, Aunt Li hurriedly comforted her. Maybe the sponge inside was smelly. Just wash it.

But Tongtong's mother said that the ones she picked up were too dirty. Who knew if someone who was sick had thrown them away, so she would grab them and throw them away.

Grandma Tongtong didn't want to see the child cry, so she said that it would be fine to wash it.

The two of you are fighting for each other, and at this moment, Tongtong's father was annoyed: "Eating, this thing is so stinky, I dragged it over the rice because I think it has no taste, and I want to add some seasoning to it. , let me loose your hands."

Saying that, Tongtong's father wanted to pull the plush toy hard.

With a click, this plush toy was torn apart from the middle.

With a "click" sound, something fell on the table.

When everyone saw this clearly, they almost fainted from fright. Where is the cotton stuffed in this stuffed toy? It's clearly a human arm! The arm was severed from the shoulder, and the forearm and forearm overlapped and were stuffed into the belly of this stuffed toy.

After it fell out, the arm was straight, the palm of the hand was facing up, and the rest of the people hadn't let go, but this hand was loose.

This arm is lying quietly on the food, like begging for a red envelope during Chinese New Year.

The family immediately called the police, and the local police station rushed to the scene first and took the arm back. They thought the case might be related to the football head case, so they reported it to the city council to see if it was the same case.

After hearing this, Elder Shao and Jiang He said at the same time, "Don't look at it, let's investigate together."

The technique was exactly the same, Jiang He had a 90% probability that it was done by the same person.

It's just that only the other arm was found, and the rest of the limbs were not found.

Jiang He said, "This is the way the murderer throws the corpse. He cuts the corpse into several pieces, and then stuffs them into different things. These things are things that won't arouse suspicion, so that he can find them before everyone else. Throw the corpse if you can't."

"Is Xingfu Community and Fengyang Street far away?" Jiang He asked.

Captain Li replied: "It's quite far. It's not in the same district at all. It will take about two hours by car."

Hearing this, Shao Shao shook his head secretly and said, "This is not easy to handle, while it's still dark, you go to inform your director, and let all the police stations below look carefully for each community, roadside, garbage In the place where things can be hidden in the pile, be sure to retrieve all the limbs of this person."

"Understood!" Captain Li saluted.

Shao Lao looked at Jiang He Xu Yiman: "The murderer spends one day and one night dismembering the body and throwing it away. If the murderer has transportation, he can throw these limbs in any corner of Shangxi City for such a long time. ."

"In this way, even if we find all the limbs, there is no way to determine where the murderer lives." Jiang He looked at the two of them.

The three of them were silent, but in their hearts, they all understood the fact that the victim's body might be hidden in any corner of the city at this moment.
