Han Bin told Zhao Ming and Tian Li about his speculation.

Tian Li found out Zhao Xiaoshan's mobile phone communication records, and also searched for those mobile phone numbers on the Internet.

"Team leader, you really guessed right, a few years ago, Zhao Xiaoshan also called for a job. ”

Because Zhao Xiaoshan disappeared after the year, there was a gap of more than ten days, so these numbers were not taken too seriously at first.

Zhao Ming interjected, "Brother Bin, let's not go to the traffic police monitoring center, compare the communication records of the two people, as long as they have the same contact number, it proves that they have been to the same company for an interview." ”

"Such a simple reason is still reminded by you, before, I have compared the communication records of two mobile phone numbers, and there is no same contact number. Tian Li said.

"If you go to the company for an interview, you have to call, if you have been to the same company for an interview, how can you not have the same contact number. Zhao Ming questioned.

"I've thought about this question too. Tian Li took over the conversation,

Zhao Xiaoshan died after the year, but the company didn't go to work during the Spring Festival, and he couldn't go to the company to apply. He should have applied for a job a year ago, which is also shown in his correspondence records, and we only printed the correspondence records of Zhao Xiaoshan for half a month before his death, is this time frame a bit short. ”

Han Bin nodded, there was indeed such a possibility, "Extend the communication records of the three deceased to one month, and then compare them." ”

"Tian Li, I'll leave it to you. ”

"Good. ”

"Brother Bin, then let's not go to the traffic police monitoring center. ”

"Go, time is pressing, we can't wait, put all our hopes on checking the communication records. Figuring out where Ren Jianhua went before he disappeared can also find clues to the suspect. ”

Zhao Ming drove Tian Li to the Yuhua Branch first, and asked Tian Li to check whether the hotel monitoring at No. 8, No. 9, No. 10, and No. 11 was covered, and if it was covered, it needed to be sent to the technical team for recovery as soon as possible.

Han Bin and Zhao Ming went to the traffic police monitoring center as planned.

According to the hotel waiter, Ren Jianhua left the hotel at 9 a.m. on the 11th.

The hotel is located near the intersection of Huacui Road and Changyuan Street.

Han Bin started from the monitoring of this intersection.

Checking and monitoring requires patience and skill, but luck is also important.

Nowadays, there are many ways to get around, and it is still difficult to find them.

The hotel is the closest to this intersection, but Ren Jianhua may not necessarily leave from this intersection.

Leaving is not necessarily on foot, but also on a bus, a taxi, a ride-hailing, a friend's car, or even a murderer's car.

Han Bin and Zhao Ming checked the nearby intersections, but they found no trace of Ren Jianhua.

After checking until six o'clock in the evening, there were still no clues, so Han Bin and Zhao Ming went home directly.

The street was still empty, and on the way back, Han Bin called his mother, originally wanting to tell her not to go home for dinner.

Wang Huifang didn't force it, but just told Han Bin that the meal was ready, and asked Han Bin to say when he was about to get home, Wang Huifang put the meal at the door of the house, and Han Bin could take it upstairs to eat.

Han Bin had to admit that his mother was still smart.

As for the words of thanks, Han Bin didn't say it, and he couldn't say it.

The love of parents for their children has become a universal instinct.

Outsiders give some good, and they are likely to take it as a confidant.

Parental love has become a habit.

Han Bin went to his parents' house, there was a green insulated lunch box at the door, Han Bin knocked on the door, chatted with his mother, grandfather, and uncle, and then took the rice upstairs to eat.

When I opened the lunch box, the food inside was still hot, very hearty, four dishes, one soup, and one rice.

Rice and soup each occupy one layer, and the four dishes are divided into two layers.

At noon, Han Bin ate casually, and his chest was pressed against his back, which was already hungry.

In less than twenty minutes, Han Bin had eaten all the meals and drank a bottle of cold Coke.

It's colder, but it's better chilled.

As long as there are conditions, Han Bin is still more particular about eating and drinking.

After the meal, Han Bin took a bath, lay on the bed and watched for a while, and then went to sleep.

......

The next morning, Han Bin put the cleaned lunch box at the door of his parents' house and went to work with breakfast from the doorknob.

In order to make it easier for Han Bin to eat on the road, Wang Huifang made a burrito, a freshly out of the pan with ham, bacon, fried eggs, lettuce, tomato slices, and a bag of hot milk, which not only tastes good, but also has comprehensive nutrition.

After arriving at the office, Ma Jingbo called a meeting to summarize the progress of yesterday's investigation.

Yesterday, Ma Jingbo took people to Cheng'an Village to make a record of the employees of Fulong Feed Factory, and investigated all the local employees, but found no clues.

There are also two out-of-town employees who could not arrive because of the closure.

Ma Jingbo decided to temporarily abandon the investigation of Fulong Feed Factory.

Investigating a case is a very complicated matter, and theory and practice are two different things.

Sometimes, solving a crime also depends on probability and luck, and the limited police force must be invested in the investigation of key clues.

Fulong Feed Factory is suspicious, but Ma Jingbo does not dare to guarantee that if he stares at this clue, he will definitely find the suspect.

Yesterday, when investigating the case at the Fulong Feed Factory, he found a lot of people watching the excitement.

This made him think of another possibility, the suspect may not necessarily be an employee of the feed factory, Zhang Jinlin and Lao Liu Tou may also be seen by passers-by when they hide the key or take the key.

Thinking about the scope of the suspect in this way is too large, so that Ma Jingbo does not dare to continue to invest a lot of police investigation.

Yesterday, Han Bin called him to complain about the lack of manpower.

Thinking of this, Ma Jingbo couldn't help but ask, "Han Bin, what is the progress of your investigation over there?"

Han Bin narrated the situation of the investigation and his own analysis in its original form.

After listening, Ma Jingbo agreed, "Yes, your analysis has some truth, since these two people have in common that they are looking for a job, then let's investigate around this point." ”

"The surveillance investigation is also very important, although the previous surveillance investigation did not find suspicious vehicles and people, but now it is two cases that can be cross-compared. If the same car or the same person is in the vicinity of the scene of two crimes, then he is very suspicious. ”

"I rearranged the task, and the video could not be checked separately, but viewed by a fixed person. The surveillance video of the two cases is viewed separately by different personnel, so there is no role in cross-comparison, and there is no great significance. ”

Zeng Ping then recommended himself, "Captain Ma, I'll take someone to check the monitoring." ”

"Yes. Ma Jingbo nodded, and was about to speak again when there was a knock on the door outside.

"Knock Knock ......"
