Zheng Kaixuan shook his head and laughed: "A group of slippery heads."

"Team Zheng, I don't understand one thing. Ten years have passed since this case, and there was no movement before. Why did someone suddenly petition this year?" Han Bin asked.

"This is also what I can't figure out. The group of people was not received by us, but by the Letters and Visits Office. The documents also contain the materials they compiled. They asked the police to catch the murderer of the case. What happened? Group to check." Zheng Kaixuan said.

"Team Zheng, won't you investigate this case with us?"

"I understand the basic situation of this case. You should first visit the victim and understand the situation. When you have any clues, I will participate in the case. Old Zeng is coming back soon. I have to get some work on my hands. Get it." Zheng Kaixuan smiled.

"Really, with such a calculation, the days for team Zeng to go are not short." Li Hui said.

"Old Zeng was the deputy squadron leader and the second team leader. When he comes back from training, he will take over as the leader of the third squadron of the criminal investigation team. You used to be with him, so I don’t need to say anything, just do it. "Zheng Kaixuan said.

Hearing this, everyone was a little sad.

Li Hui couldn't help asking: "Team Zheng, you stepped down as the squadron leader, then which department are you going to go to in the future?"

"You don't need to worry about you kid. Even if I am not the squadron leader, I am still the deputy commander. It is your leader." Zheng Kaixuan scolded with a smile.

Han Bin knew that Zheng Kaixuan was going to the provincial government for training, and he was not worried about Zheng Kaixuan's future.

"I have put all the materials here. I suggest you look at the materials first, then visit the families of the victims to find out the situation before proceeding with the next investigation." Zheng Kaixuan finished speaking and left the office.

"Everyone has heard what the Zheng team said, and started to examine the materials separately, and strive to thoroughly understand the materials today, and we will visit again tomorrow to make transcripts." Han Bin arranged.

Han Bin deliberately found out Liang Zhibo's materials and compared the footprints on the scene with his shoe print photos. After a detailed comparison, Liang Zhibo had indeed been to Lu Jiawei's house.

This case had a great impact that year. A 715 task force was deliberately set up. There were as many as nine victims. In addition to the main suspect, Lu Jiawei, there were also several suspects.

There is still a difference between investigating old cases and investigating new cases. Han Bin hopes to find out the key points and sources from numerous materials.

On this day, the second group did not go out and stayed in the office to read the materials.

...

The next day.

nine in the morning.

Han Bin held a meeting in the office.

"I read the file for one day yesterday, and you can talk about what you think." Han Bin said.

"I think the key to the case lies in Liang Zhibo. He is the most likely murderer. If he can be found, the case will be solved." Li Hui said.

Han Bin didn't answer the conversation. It was natural to say that when he found it, it would be useless to find nothing. What's more, Liang Zhibo was so good at catching it, and he wouldn't wait so long.

"The scene of this case was burned down, and a lot of evidence was burned, but the dead at the first scene were two people after all. I think the suspect may be a gang committing the crime. It is difficult for one person to kill Lu Jiawei and his wife." Tian Li analysis.

"According to Sister Tian's analysis, we can check people who have a close relationship with Liang Zhibo to see who is still suspected of committing the crime and time." Zhao Ming said along the way.

"Ten years have passed. Liang Zhibo's clues are not easy to investigate, and Liang Zhibo's family may not cooperate." Sun Xiaopeng said.

Han Bin walked to the front and pulled out a white board from the wall, pasted Liang Zhibo's photo on the left, and the photos of Lu Jiawei and Zhang Shufeng on the right, and then took the whiteboard marker to mark the suspect and the victim.

The whiteboard was obtained from the Logistics Department yesterday, and it is more convenient to use than a projector.

"Our current understanding of the 715 case is limited to the information and dossier. The actual investigation I intend to start from two aspects, one is investigating the suspect, and the other is investigating the victim." Han Bin finished, and pointed. Pointing to Li Hui on the side:

"Li Hui and Xiaopeng will investigate Liang Zhibo's situation; Zhao Ming and I are responsible for investigating the victim's situation."

"Group leader, what about me?" Tian Li asked.

Han Bin took out another photo, put it under Liang Zhibo, and fixed it with red magnetic particles: "This is a blood fingerprint found at the crime scene. The blood has proven to be Zhang Shufeng's blood, but whose fingerprints have never been. Found it."

"Ten years have passed since the case, and the fingerprints were not successfully compared at the beginning. It doesn't mean that they cannot be compared successfully now." Tian Li said.

"That's right, you will send your fingerprints to the technical team in a moment, and let Ruben compare it with the database again." Han Bin ordered.

"Yes."

"Liang Zhibo has a wife and a daughter. You can check their communication records to see if there is anything unusual."

"Understood." Tian Li nodded.

"OK, let's start to split up."

...

Forty minutes later, Xidiying Village.

Before investigating the victim, Han Bin planned to take a look at the scene of the original crime. After all, the files were just information and did not feel like being there.

Ten years have passed, and Xidiying Village has already returned to its former calm.

Xidiying Village is close to the Qindao urban area. The villagers in the village are all working in the city and the conditions are pretty good.

Han Bin and Zhao Ming went near the scene of the 715 case and found the alley where the case was committed based on the image on the photo.

Zhao Ming looked around, pointed to a nearby place and said, "Brother Bin, it seems that the crime scene is in front. You see there are two other destroyed houses."

Han Bin nodded, his eyes fell in the alley, two old men sitting in Mazha and basking in the sun.

One of the old men is already bald.

Another old man had a scar on his hand, which looked like a burn mark.

Han Bin walked over, took out a box of cloud smoke, and handed one to the two old men.

"Two uncles, ask you something." Han Bin smiled.

The bald old man glanced at Han Bin and Zhao Ming, and pinned the smoke to his ears: "What's the matter?"

"I think the houses in this hutong are all well built, why are those two houses so pitch-black and unoccupied," Han Bin asked.

"Those two houses burned to death. The family in the east was unhappy and moved to the city; the adults in the house in the west were all burned to death, and only one child was left. "The bald old man said.

According to the old man's words, combined with the facts of the case, the house on the west should belong to Lu Jiawei and Zhang Shufeng, and the house on the east should have been burned and died of serious injuries.

"What do you do?" the bald old man asked.

"Uncle, what do you think we want to do?" Zhao Ming asked with a smile while holding a briefcase in his hand.

The uncle bald curled his lips, he looked like the uncle I eat more salt than you eat: "You are here to buy a homestead."

"Uncle, how did you tell?" Han Bin asked.

"We are about to requisition land here. As soon as the news spread, the price of homesteads has been rising. There have been several calls in the past few days," said the bald uncle.

Han Bin himself lit a cigarette and turned his head to look at the old man with scars on his hands. The other party remained silent.

"Master, what do you think we do?"

The old man with scars on his hands took a look at Han Bin and Zhao Ming, and took a deep breath: "Are you the police?"

Han Bin gave a thumbs up: "Master, good eyesight!"

"Are you really the police?" The old smoking man shook his hand and the ashes fell to the ground.

Han Bin showed the police officer ID: "Look at it yourself."

"It seems that the kid is right, this trick is really useful." The uncle with the scar on his hand muttered to himself.

"Master, what is your last name?"

"My name is Lin."

"Who is the kid you just mentioned?" Han Bin asked.

"That guy from the Lu family, let us go to the district government to petition, saying that as long as we go, the police will re-handle the case and find the **** who set fire." Uncle Lin touched the scar on his hand. A word squeezed between the teeth.
