"Diet?" Wu Xuerui widened her eyes and then woke up: "Are you talking about his accomplices killing people to silence?"

"Yes, this is based on their personality and psychology." Song He slowly analyzed: "I call the person who kills Chenghui an impulsive person. Because he has impulsive personality, cruel methods, and a little disregardful style. However, his robbery method is relatively sophisticated, and obviously he has had relevant experience in committing crimes before.

"I call him a submission person the second person who has traces left on the scene. He is cowardly and obeys powerful people, but he is afraid that others will hurt him, so he has been standing far away and will not take action to stop the angry impulser, because he dares not, he is afraid of angering the impulser. And everything he does has only one purpose, that is, to protect himself. I even suspect that he is a robbery gang that was threatened to join.

"I call him the observer to stop the impulsive. He was very calm during the entire robbery, probably the leader of the gang, because even when the impulsive was furious, he dared to come forward to stop it.

"After the incident, all traces were erased, obviously very cautious. And he had a lot of experience and would not easily reveal his existence.

"The most important thing is that this man is cold-blooded and decisive, able to watch the impulsive vent his anger and kill people, and stop him when he vents almost."

"I understand. They have committed robbery crimes before, so they are so skilled. In addition, they have the constraints of observers, and have never caused serious consequences." Wu Xuerui analyzed: "It is also this reason that impulsive people will become more and more unscrupulous after committing several crimes until they meet Cheng Hui."

"You are right." Song He nodded: "If I were an observer, it would be better to have an impulse, such a tool to take action on my behalf. However, an impulse who is prone to losing control and about to be exposed will inevitably lead to the observer being implicated, and the best way is to make him disappear."

"I'm afraid that when Cheng Hui hurts the impulsive, the observer decides to abandon him." Wu Xuerui agreed with Song He's statement, and then became a little puzzled: "In this way, we have two directions of investigation, one is the dead impulsive, and the other is the surrender. But we can't conduct an investigation through the province."

"Yes, the problem is here. If we investigate from the perspective of the submitter, we need to summarize the characteristics of the submitter." Song He spread his hands and smiled: "But do you have a way to obtain relevant robbery case files from Yuncheng six years ago?"

Wu Xuerui shook her head dejectedly. The police station system is not omnipotent, and the records of old cases are not comprehensive. It is okay to say that major cases are, but cases that have been old and have not caused serious consequences are hanging.

"Besides, I don't believe that Cai Mingwu will not conduct relevant investigations in secret, so there is no need for us to go deeper from this direction." Seeing this, Song He sighed: "So, we only have one investigation direction."

"The dead impulse?" Wu Xuerui understood a little.

"You must know that the observer must kill the impulsive before he is exposed. With the impulsive temper and eye injury, the longer he is not treated, the easier it is to lose control. So I guess the calmer will take action before dawn and throw the body!" Song He paused and said to Wu Xuerui: "We divide the labor. I need a map of Yuncheng, and then start from the crime scene to check the surrounding areas where the body is suitable for throwing the body. You can find out if there are any bodies similar to the impulsive after Cheng Hui's death."

"Okay!" Wu Xuerui returned to her office quickly and turned on the computer again. After a while, the map of Yuncheng was delivered to Song He, and there were ten A4 papers.

Song He looked at the map, closed his eyes, and spliced ​​it one by one in his mind, gradually drawing a map containing the towns around Yuncheng City.

He calmed down and determined the location of the crime, slowly deduced the psychological changes of the observers and impulsives. Putting aside the locations that were not easy to kill and throw away the bodies, and then combined with the time of the crime, he finally roughly determined a range.

But this is still not enough, because this roughly range includes several villages and towns.

"No, it's too big. Onlookers must ensure that they throw their bodies at two o'clock. One is that they are secluded enough, and the other is that no one will notice it in a short period of time." Song He closed his eyes and said silently: "The incident occurred on autumn nights, and farmlands were impossible. It was the busy farming season. It was impossible near the residential area, and there might be witnesses at night. It is even more impossible next to the main road. It is not a joke to be discovered when the vehicle passes. It is also necessary to leave time to hide. Damn it, where is it?"

Just as Song He Ming was thinking hard, Zhao Congjun walked out of the office, and two middle-aged men came out together.

Song He opened his eyes when he heard the sound and found a man with short beards smiling and said to Zhao Congjun: "If Director Zhao has the opportunity to come to our Yuncheng, please notify us so that we can do our best to the landlords. Our little white dragon in Yunjiang is a unique one."

"Captain Tang, don't worry, I'm going to go, sometimes it's time to bother you, haha." After saying that, he shouted at the same time: "Who will help me send team Tang and team Cai."

Zhou Kai responded, got up and left with the two of them.

Song He looked at Cai Mingwu who had never spoken and said intently: If it weren't for the system, who would have thought that you had such a big secret?

Suddenly, Song He felt a stir in his heart, and quickly came to Wu Xuerui and whispered: "Since the case, have any corpses been found along the Yunjiang River until now."

Wu Xuerui's eyes lit up, and the Yunjiang River ran through Yuncheng, which happened to be near the crime scene!

"I have it!" Wu Xuerui only searched for a moment and found it: "Five months after the incident, half of the corpse was found during the salvage process of the fishing boat in Yunjiang. After the identification department restored it, the deceased was a male, and his body characteristics were similar to those of the impulsive one!"

"Thank God, God is still on our side." Song He breathed a sigh of relief: "At that time, there were still nine months before Cai Mingwu was transferred to the criminal police team, and he could not get in touch with this case. When he joined the criminal police team, this case had become one of many unsolved cases. It was not that he was deliberately looking for it, and he would never find it."

"It's not a unsolved case, because there is no case filed at all, and there are only some records in the system." Wu Xuerui shook her head and said, "After the body was salvaged, the appraisal department restored the appearance of the deceased, issued a reward notice, and was taken away three months later."

"Have you taken it away? Three months?" Song He raised his eyebrows in surprise: "Who is the person who took it away? Is there any record?"

"There is only one name and ID number." Wu Xuerui clicked a document and said, "Jiang Qinghua, ID number is said to be the deceased's fellow villager. He used to have contact occasionally, but later he lost contact."

"Have you investigated?" Song He asked.

"Yes, after all, it's a human life, but the investigation results show that there is nothing wrong with this person." Wu Xuerui understood what Song He said, and added: "The police officer visited the deceased's friend and said that he had alcoholism and many bad habits, had a bad temper, and had a poor interpersonal relationship. The last time he appeared was to eat and drink with his friends at someone else's wedding banquet. As a result, he drank too much and never appeared again after leaving the wedding banquet."

"So the local police officers determined that it was an accidental death caused by falling from the river after drinking?" Song He frowned: "This decision is too hasty."

"I understand that most people will float up after drowning in a few days, but the Huayun District Police Station, who made the identification, has their reasons."

Wu Xuerui looked at the report in the system and said: "There is an omnivorous freshwater fish in Yunjiang, called Snow Pompeoensis, also known as Xiaobailong. It is usually good, but once you smell the blood, it will swarm and become very dangerous. However, because the meat of this fish is delicious and is the favorite edible fish of the locals, there is a special breeding area in Yunjiang, and the corpse is found in the breeding area.

"The local police determined that the deceased wanted to steal the snow pompeo after being drunk, but accidentally got injured and fell into the river, causing him to be attacked by the snow pompeo and did not leave a complete body. The police station in Huayun District said that there had been the same case before, which was exactly the same as the characteristics of this corpse."

Song He still frowned. It is said that the criminal died, Cai Mingwu could no longer find his target, and there was no way to talk about revenge.

However, there are two people in the three-person criminal gang at large, especially the bystanders, who are the most dangerous among the three, but they hide the deepest.

Wu Xuerui was also indignant. Whether it was her, Zhao Congjun or other senior brothers, they had the same attitude towards criminal behavior, which means they would never tolerate it!

But now the Huayun District Police Station of Yuncheng has closed the case first and lost firearms behind her, which makes her unable to see it.

"No matter what, Cai Mingwu will not have any problems for the time being, this is the best result." Song He paused and comforted Wu Xuerui and said: "As for Cheng Hui's case, we will find an opportunity to settle it in the future. Also, don't tell your master about this matter, otherwise you can think of the consequences with his temper of jealousy."

When Wu Xuerui heard this, she nodded helplessly. It was difficult for both of them to investigate the case across the district. If they crossed the province, they would not even think about it at their current level, so they could only do this.

In fact, compared to Wu Xuerui's helplessness, Song He was in a more complicated mood. Both Cai Mingwu and the criminal made him feel helpless.

This feeling is different from the inability to tell the story of Bai Hewei at the beginning, but it is a feeling that makes people feel depressed, as if they are walking on a road where they can see the end but can't finish it no matter how hard they go.

Song He let out a long sigh, sorted out his thoughts, and remembered the name Jiang Qinghua. If his guess is correct, the key point of solving the case lies with this person. So sooner or later, he will find this person, and then there will naturally be a way to dig out what he wants.

Seeing Wu Xuerui asking Zhao Congjun to report the exchange meeting, Song He followed. Wu Xuerui was in a low mood. Even if she didn't say it, the possibility of being seen was extremely high.

When he walked into Zhao Congjun's office, he saw him looking at Wu Xuerui curiously. Song He quickly smiled and said, "Old Zhao, fortunately, he has not been humiliated and completed the task successfully."

Zhao Congjun turned his gaze to Song He, then looked at Wu Xuerui, as if he understood something, stared at Song He's head and said, "I found out that you are floating! You dare to make that person angry before you do anything? Apologize to me quickly, otherwise I won't spare you!"

Wu Xuerui: "Hmm?"

Song He: "Hey?"

Lao Zhao, please wait, what are you thinking about in your mind!

After Song He repeatedly explained, Zhao Congjun finally believed that he had not done anything to Wu Xuerui. After all, his apprentice covered his mouth and laughed at him, which was not like the reaction after being bullied. As for Wu Xuerui's other things, he would not worry as long as he didn't ask for him. Anyway, Song He's loyalty

Walking out of Zhao Congjun's office, the shadow in Wu Xuerui's heart dissipated a lot, and the corners of her mouth were raised, and she kept having fun.

Seeing this, Song He smiled wickedly: "Ware you smile a little longer now, your master has already handed you to me in his subconscious mind."

Wu Xuerui was stunned when she heard this, her mind turned around and she realized, and her eyebrows stood up: "Get out!"

"I seriously doubt your senior brothers will do this."
