Although the series of thefts were complicated, they were investigated methodically under the auspices of Zheng Kaixuan.

During this period, Xu Yan, the first informant, came twice to ask about the progress of the case.

Her father will have an operation tomorrow. She is very anxious and hopes to solve the case today.

The members of the criminal police team have been investigated separately, and Zheng Kaixuan cannot give her exact time to solve the case without analysis and summary.

At three o'clock in the afternoon, several personnel with previous records summoned by a group had already finished their transcripts.

The second group, Li Hui, Zhao Ming, and Tian Li, also checked the surveillance.

Zheng Kaixuan called everyone to the conference room and prepared to summarize the facts of the case. The clues are not one-liner. Sometimes they can confirm each other to find the suspect more accurately.

Time is running out, Zheng Kaixuan did not have any opening remarks, and directly asked: "Li Hui, did your second group's investigation and monitoring find out?"

"We checked the monitoring of elevators, gates, and underground garages before and after the time of committing the crime, but none of the suspicious persons were found." Li Hui said.

"Is it clear?"

"Yes." Li Hui nodded and analyzed: "We guess that the reason why the suspect did not appear in the surveillance should have two possibilities. The first possibility is that the suspect did not leave the community, or even the residents of the community. ."

"go on."

"The second possibility is that the spider man commits the crime. Linfang community is surrounded by second-story shops. If the suspect can climb up to 30 floors, he can leave without going through the gate and climb out directly from the surrounding shops. Li Hui explained.

"Team Zhao, what do you think?" Zheng Kaixuan asked.

"We have made transcripts of personnel with a history of theft, including the spider man Zhang Deshui. Based on his testimony, we have investigated his whereabouts. The time of the crime was not in the city, but went to the mountains to teach students rock climbing. You can rule out his suspicion." Zhao Ying said.

"At present, are there any other suspects?" Zheng Kaixuan asked.

"According to the clues provided by Zhang Deshui, someone looked for him after he was released from prison and asked him about his experience of stealing and climbing at heights. I think this person is also very suspicious."

"Do you know the identity of this person?"

"Zhang Deshui is not familiar with him, only knows his nickname is Yongzi."

"What do you think?"

"According to the current clues, the suspect should have entered the room through a window, and high-altitude theft requires a high quality of the suspect. I think this is a very important investigation direction." Zhao Ying analyzed.

"Yeah." Zheng Kaixuan nodded: "Check this nickname is Yongzi."

"I have been looking for someone to check."

Zheng Kaixuan glanced, a group of players were present, Zhao Ying should have used an informant, he did not ask much.

"Boom."

There was a knock on the door outside the meeting room, and then Han Bin opened the door and walked in.

"Team Zheng, Team Zhao."

"I'm back." Zheng Kaixuan pointed to the chair next to the conference table and motioned Han Bin to sit down: "Research the scene again. Did you find it?"

Han Bin picked up the mineral water on the side and took a sip: "Nothing found."

"I didn't find it, your kid is still running outside for so long." Zheng Kaixuan hummed.

"I went to the scene this time and surveyed the vicinity of the glass window again to see if the suspect left obvious shoe prints when he climbed, but after some survey, whether it is the window stand or the outside wall, There are no shoe prints for climbing." Han Bin said.

"The exterior walls of the building are relatively hard. As long as the soles are not dirty, it is difficult to leave clear shoe prints." As an old criminal policeman, Zhao Ying also has some understanding of footprint identification.

"You are right, I thought so at the beginning." Han Bin replied, changing the subject:

"Later, I asked Zhao Ming to take a side view of the exterior wall of the floor with a drone, and found that the exterior wall was very clean, and there were no signs of climbing."

Zheng Kaixuan has rich experience, and he immediately saw the problem; "The suspect must be borrowed during the climbing process. Even if there are no obvious shoe marks, there will be traces of climbing."

"It is also based on this clue, I speculate that the suspect did not climb into the room." Han Bin said firmly.

A team of team members Wei Zimo had doubts: "If you didn't enter the room through the window, why the glass in each house was either open or damaged."

"It may be misleading the police and investigating along the wrong clues. As long as you follow the clues of climbing high, you will not find him." Zheng Kaixuan analyzed.

"What about aerial video?" Zhao Ying asked.

"Here." Han Bin handed a tablet to Zhao Ying, who was aside.

Zhao Ying checked it carefully and sighed; “There are indeed no signs of climbing. It seems that the suspect entered the room through a window.”

Seeing Han Bin showing his face, Li Hui's backs straightened up a lot, but Zeng Ping was absent, and the three of them were lacking in confidence.

Coupled with the short time for the establishment of the second group, whether it is the number of crimes solved or the detection rate, it has been suppressed by the first group until Han Bin joined the second group, and this situation changed.

"Team Zheng, judging from the surveillance investigation, no trace of the suspect was found. According to previous judgments, the suspect probably did not leave the community or was a ‘Spiderman’.”

Li Hui coughed lightly and struck while the iron was hot: "The possibility of spider-man can now be ruled out. Then, I guess the suspect may be hiding in the community, or the residents of the community."

"I investigated a person with a history of theft today. He lives in Linfang Community." Zhao Ying said.

"What about people?"

"Let it go." Zhao Ying sighed and explained:

"His name is Chen Kangning, he is 176 in height and weighs about 190 kg. Because of the direction of investigation at the time, the suspect should have climbed into the room from the window, so he was temporarily ruled out."

"The recorded video of the law enforcement recorder." Zheng Kaixuan said.

"Yes." Wei Zimo got up and left the meeting room.

It didn't take long for Wei Zimo to return, holding a USB flash drive in his hand, inserting the video into the computer, and playing it on a projector.

The video shows a fat man sitting on a chair. He seems to feel that the chair is a bit small and twists his body.

"Name, gender, age, hometown..."

"Chen Kangning, male, 29 years old..."

"Chen Kangning, I invite you over today. Is there something I want you to assist in the investigation?"

"what's up?"

"A theft occurred in Linfang community, do you know?"

"I haven't heard, when?"

"Just yesterday morning."

"Police officer, what do you mean by calling me?" Chen Kangning looked calm.

"We would like to ask at 11 o'clock in the morning on August 11th, and at 5 o'clock in the morning on August 12th, where are you?"

"Are you suspicious of me?"

"It's just a routine inquiry."

"I admit that I made mistakes before, but I have not done it. I am now a legal citizen and have a legitimate industry." Chen Kangning showed indignation.

"Don't get excited, we are just making a transcript, not an interrogation." Wei Zimo comforted.

"If something goes wrong, you should investigate me and let me not get excited. I just want to be a normal person. Is that so difficult?" Chen Kangning clenched his fists and showed aggrieved expression.

Chen Kangning's remarks moved many police officers a little.

Especially Zhao Ming, Tian Li, etc., all the young police officers looked a little ugly.

Zhao Ying's eyes were firm. Judging from the traces of the investigation on the scene, this series of cases was definitely done by veterans. Investigating people with a history of theft is the correct direction for investigation.

When Zhao Yinggang was a criminal police officer, he was willing to give people with criminal convictions a chance, and he was also willing to try to believe them.

However, many years of experience from the police prove that the possibility of criminals committing crimes again is much higher than that of ordinary people.

For a criminal policeman, reason is more important than emotion.

If you want to fight crime, you must be more rational.

In order to better protect the safety of the people.
