Seongnam Prison Monitoring Center.

The monitoring center is in an office of more than 20 square meters, or the old-fashioned computer screen, each machine is responsible for monitoring different areas.

There were only two prison guards in the monitoring room, and when they saw Zhu Haijian coming in, they hurriedly stood up and saluted.

Although Han Bin has never worked in the prison system, he has never eaten pork, and he has also seen pigs run.

During the training, they also visited some prisons, and the one that impressed him the most was Quancheng No. 2 Prison.

This is a newly built prison, and the other facilities are not mentioned for the time being, and the monitoring room alone is much worse.

The monitoring room of Quancheng No. 2 Prison is completely modernized, similar to the traffic police monitoring center, with an entire wall made into a large screen, and a row of computers a few meters away, in front of which four police officers sit to check the monitoring situation of each one.

After a brief introduction by the two sides, Han Bin and the three of them began to check the monitoring.

Han Bin is responsible for checking Zhu Weichao's monitoring, Li Qin is responsible for viewing Li Dongzhi's monitoring, and Bao Xing is responsible for checking Wang Lifei's monitoring.

The most important thing in checking monitoring is carefulness, patience and observation, Han Bin's observation is the strongest, but in terms of carefulness and patience, it is not as good as Li Qin.

Han Bin checked the surveillance of the prison visit room, and the surveillance video was not long.

There are regulations on the length of visits in prisons, and meetings are allowed once or twice a month for 30 minutes each time, and if special circumstances require an extension of time, it is necessary to obtain approval from the competent professional department, but the maximum is not more than one hour.

The surveillance video of the prison visit room can only be stored for more than a month, during which Zhu Weichao visited twice, once with his wife Mao Yamei, and once with his younger brother Zhu Wei'an.

The prison visit room is an oval room, inside are the prisoners, and the outside is the family members of the prison visitor, and there is tempered glass in the middle, so you can see each other, but the tempered glass has a certain soundproof effect, and the chat needs to be through the old-fashioned blue telephone.

"Wardens, is there a recording of the blue phone in the visitor's cell?"

"Yes. ”

"Please call up the recording of the call of the three people. ”

"Wait a minute, I'll arrange it. ”

Taking advantage of this, Han Bin took a look at the surveillance video of the visit, which was monitored at the top of the house, and the angle was not very good, and he could only vaguely shoot the side face, but he could distinguish the identity of the visitor.

Han Bin compared, and the people who visited him were indeed Li Hongshan and Li Dongmei.

Although Han Bin understands lip language, from this point of view, it is difficult to see the complete mouth of the two people, with local characteristics, he can only distinguish some special mouth shapes, but what he talked about as a whole, Han Bin can't accurately judge.

Fortunately, Zhu Haijian brought the recording of the call to visit the prison, and Han Bin and the three began to listen to the recording.

When he said it, the recording effect was not very good, and Zhu Weichao's younger brother had some accents, Han Bin had a hard time listening, and sometimes he had to pause to think about what the other party meant.

Han Bin made a record with Zhu Wei'an, and felt that the other party's Mandarin was okay, but in the call recording, he had been talking to Zhu Weichao about his hometown.

Ten miles of different sounds, a hundred miles of different customs, even if everyone is from Qindao City, Han Bin still has some difficulty listening.

Zhu Weichao obviously speaks Mandarin well, but he wants to speak his hometown dialect in the surveillance recording, in Han Bin's opinion, there should be two possibilities.

The first possibility is that he did it on purpose, that is, he wanted the person listening to hear it clearly, and deliberately wanted to hide something.

In the second case, it was an instinct and not something he did on purpose.

This situation is also very common in life, and if you look closely, you will see that many people can speak both their native dialect and Mandarin.

You may use Mandarin to communicate with your friends, but when you see your mother, you can't help but speak your hometown, which you may not have noticed.

Han Bin has this kind of experience, and the reason for this situation, Han Bin also feels that there are two possibilities, the first is because he is used to it, and it is a physiological instinct to always speak his hometown dialect to his mother when he was a child.

The second is that your mother spoke your hometown dialect first, and also hooked your hometown dialect.

Zhu Weichao's brother called the recording, Han Bin listened very carefully, after listening, he didn't find any problems in the conversation between the two, nor did he talk about the prison escape, and there was no allusion.

Han Bin analyzed that the reason why Zhu Wei'an spoke his hometown dialect was that the second possibility was greater, it should be that he couldn't help but speak his hometown dialect when he saw his brother.

Just when Han Bin wanted to listen to it again, Li Qin on the side shouted, "Team leader, I have found a problem here." ”

"What's the problem?"

The recording of Li Hongshan's call to visit Li Dongzhi seems to be alluded to. Li Qin took out a pen and paper and wrote a few words, 'New house, east side, motorcycle, pick you up.' ’

Subsequently, Li Qinyou played a recording, "Dad, how are you doing lately?"

"It's good, I just went to check it out some time ago. ”

"My son can't be filial in front of me, I'm sorry for you, tell Dongmei what you want to eat, you must be good. ”

"Don't worry, I'll be fine, I'm going to wait for you to come out, watch you marry your daughter-in-law and give birth to a big fat boy, and inherit the lineage for our old Li family. You also have to behave well in it and try to come out early. ”

"I will, I'm going to do well. ”

"That's good, I've prepared a new house for you, just east of the old house, and when you let it out, Dad asked someone to pick you up. ”

"I know, I will definitely behave well and will not disappoint your old man again. ”

"That's good, that's good......"

The recording was paused at this point.

Li Qin said to Han Bin on the side, "Team leader, do you want to listen to it again." ”

Han Bin nodded, "Put it again." ”

Moments later, the recording sounded again, and the crowd listened carefully again.

Han Bin is basically sure that there is indeed something wrong with this recording.

The recording in question is mainly focused on one sentence, "That's good, the new house has been prepared for you, just east of the old house, and when you release it, Dad asked someone to pick you up." ”

The superficial meaning of this sentence seems to be that an old man is looking forward to his son's early release from prison, if he doesn't know the actual situation, he may really believe it, but Han Bin has been to Li Hongshan's house and knows the conditions of his family.

Li Hongshan's house doesn't look like it can buy a new house.

In Han Bin's opinion, there is another level of understanding in this sentence, your hiding place has been found, just east of the prison, and someone will come to pick you up at that time.

The two were very careful in their conversations, and the rest of the conversations were normal, but this sentence had a deep meaning.

If he had not been to Li Hongshan's house on the spot, and there was no accurate way to judge his family conditions, it was naturally impossible to judge whether Li Hongshan was capable of buying a house.

According to the time of the call recording, Han Bin played back the surveillance video, compared the two, and found that when he said that sentence again, Li Hongshan seemed to hold his chin with his hand, which was also the only time he held his chin in the whole conversation.

If you look at the video alone, you may not notice that there is anything wrong, but when you look at the call recording, it seems to be a signal.

"Sister Li, do you think this Li Hongshan may be the one who helped Zhu Wei get out of prison?" asked Han Bin.

Li Qin replied, "I prefer that he is just helping to deliver the news, and it is not clear whether he is the person who answers." ”

"Moreover, Li Hongshan's grade is relatively old, and his physical condition is not very good, so it is very difficult for him to kill. ”

Bao Xing said, "I think this just explains why the murderer added sleeping pills to the liquor to stun Zhu Weichao." It shouldn't be difficult to kill someone in this situation. ”

"Tsk, this old man can really pretend, and he was almost deceived by him. ”

Regardless of whether Li Hongshan was the murderer of Zhu Weichao or not, it is basically certain that he was a participant in the prison escape case.
