Detective from the future

Chapter 431 Cross Comparison
Han Bin told Zhao Ming and Tian Li about his speculation.

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

"Team leader, you really guessed it right. Years ago, Zhao Xiaoshan also called for job hunting."

Because Zhao Xiaoshan disappeared only a few years later, with an interval of more than ten days, these numbers were not taken 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 interviewed by the same company."

"I need you to remind me of such a simple truth. I have compared the communication records of the two mobile phone numbers before, and there is no identical contact number." Tian Li said.

"When you go to a company for an interview, you have to call. If you have been to the same company for an interview, how could you not have the same contact number?" Zhao Ming questioned.

"I've thought about this question too." Tian Li took up the conversation,
"Zhao Xiaoshan died a year later, but the company does not work during the Spring Festival, and he has no way to apply for a job in the company. He should have applied for a job years ago. This is also shown from his communication records, but we only printed the death of Zhao Xiaoshan. For the communication records of the first half month, isn't this time frame a bit short?"

Han Bin nodded. There is 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."

"it is good."

"Brother Bin, shall we go to the traffic police monitoring center?"

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

Zhao Ming drove Tian Li to the Yuhua sub-bureau first, and asked Tian Li to check whether the hotel surveillance on No. 8, No. 9, No. 10, and No. 11 was covered. If it was covered, it needs to be sent to the technical team to restore it as soon as possible.

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

According to the hotel attendant, Ren Jianhua left the hotel at 11 am on the [-]th.

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

Han Bin started to investigate from the surveillance at this intersection.

Checking and monitoring not only requires patience and skill, luck is also very important.

There are so many different ways of transportation now that it is difficult to find them.

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

Leaving may not necessarily be on foot, and it is also possible to take a bus, taxi, online car-hailing, a friend's car, or even the murderer's car.

Han Bin and Zhao Ming checked all the nearby intersections, but they didn't find any trace of Ren Jianhua.

After six o'clock in the evening, there was still no clue, so Han Bin and Zhao Ming went home directly.

The street was still empty. On the way back, Han Bin called his mother, and originally wanted to tell her that he would not go home for dinner.

Wang Huifang didn't force it either, but just told Han Bin that the meal was ready, and asked Han Bin to say it 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 smarter.

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

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

If outsiders give some favors, they will probably be regarded as confidants.

Parental love has become a habit.

Han Bin went to his parents' house, and 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 went upstairs to eat with the food.

Open the lunch box, the food inside is still hot, very hearty, four dishes, one soup, one rice.

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

At noon, Han Bin ate something casually, and his chest stuck to his back when he was already hungry.

In less than 10 minutes, Han Bin finished all the meals and drank a bottle of iced Coke.

Although the weather is colder now, the iced taste is better.

As long as conditions permit, Han Bin is more particular about eating and drinking.

After the meal, Han Bin took a shower, read a novel while lying on the bed, and then fell asleep.

……

In the morning of the next day, Han Bin put some of the cleaned lunch boxes at the door of his parents' house, took his breakfast from the doorknob, and went to work.

In order to facilitate Han Bin to eat on the road, Wang Huifang made burritos. A freshly baked pancake is rolled with ham, bacon, fried eggs, lettuce, tomato slices, and a bag of hot milk. It is not only delicious, but also nutritious. Also comprehensive.

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

Yesterday, Ma Jingbo took people to Cheng'an Village, made notes for 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 couldn't arrive because of the lockdown.

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

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

Sometimes, solving a case also depends on probability and luck, and limited police force must be devoted to key clues for investigation.

Fulong Feed Factory is suspected, but Ma Jingbo can't guarantee that if he keeps track of this clue, he will definitely find the suspect.

Yesterday, when investigating the case at Fulong Feed Factory, he found many spectators.

This made him think of another possibility. The suspect may not necessarily be an employee of the feed factory. When Zhang Jinlin and Lao Liutou hid or retrieved the keys, they might also be seen by passers-by.

The scope of thinking about suspects in this way is too large, which makes Ma Jingbo dare not continue to invest a lot of police force in the investigation.

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

Thinking of this, Ma Jingbo couldn't help asking: "Han Bin, what's the progress of your investigation?"

Han Bin recounted the investigation and his own analysis.

After listening, Ma Jingbo agreed, "That's right, your analysis makes some sense. Since the two people have the same thing in looking for a job, let's investigate around this point."

"The monitoring investigation is also very important. Although the previous monitoring investigation did not find any suspicious vehicles and persons, there are now two cases that can be cross-compared. If the same vehicle or the same person appears near the scene of the two cases, then He is very suspicious."

"I'll rearrange the tasks. The videos cannot be checked separately, but by fixed personnel. The surveillance videos of the two cases are viewed separately by different personnel, so there is no cross-comparison effect, and it doesn't make much sense."

Zeng Ping recommended himself, "Captain Ma, let me lead someone to check the monitoring."

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

"Dong dong..."
