Han Bin told Zhao Ming and Tian Li about his speculation.
Tian Li found Zhao Xiaoshan's phone records and searched them online.
"Team Leader, you guessed it right. Zhao Xiaoshan also called for a job before Chinese New Year."
Because Zhao Xiaoshan only disappeared after Chinese New Year, and there were more than ten days between then, these numbers were not taken seriously at first.
Zhao Ming interrupted, "Brother Bin, let's not go to the Traffic Police Surveillance Center. Let's compare the two people's records. As long as they have the same number, it proves that they went to the same company for an interview."
"I don't need you to remind me of such a simple principle. Previously, I compared the records of the two numbers, and they didn't have the same number," Tian Li said.
"You have to make a phone call if you want to go to the company for an interview. If you went to the same company for an interview, how could you not have the same contact number?"
"I've thought about this too," Tian Li said.
"Zhao Xiaoshan died after Chinese New Year, but the company doesn't work during Chinese New Year, so he couldn't go to the company for an interview. He probably went for a job before Chinese New Year. This is also shown in his records. We only printed the records of Zhao Xiaoshan's phone half a month before his death. Isn't this a little too short? "
Han Bin nodded. This was indeed a possibility. "Extend the phone records of the three victims to one month and then compare them."
"Tian Li, I'll leave it to you."
"Okay."
"Brother Bin, are we still going to the Traffic Police Surveillance Center?"
"Yes, time is running out. We can't just wait and put all our hopes on checking the phone records. If we find out where Ren Jianhua went before he disappeared, we can still find clues about the suspect. "
Zhao Ming drove Tian Li to Yu Hua Branch and asked Tian Li to check if the surveillance cameras of the hotels on the 8th, 9th, 10th, and 11th were covered. If they were, they had to be sent to the technical team to recover.
Han Bin and Zhao Ming went to the Traffic Police Surveillance Center as planned.
According to the hotel staff, Ren Jianhua left the hotel at 9 am on the 11th.
The hotel was located near the intersection of Huacui Road and Changyuan Street.
Han Bin started his investigation from the surveillance cameras at the intersection.
Checking the surveillance footage not only required patience and skill, but luck was also very important.
Nowadays, there were many different modes of transportation, so it was quite difficult to find them.
The hotel was closest to this intersection, but Ren Jianhua might not necessarily leave from this intersection.
He might not have left on foot. He might have taken a bus, a taxi, an 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.
At six o 'clock in the evening, there were still no clues. Han Bin and Zhao Ming went home directly.
The street was still empty. On the way back, Han Bin called his mother. He wanted to tell her that he wouldn't be coming home for dinner.
Wang Huifang didn't insist. She just told Han Bin that the meal was ready and asked Han Bin to let her know when he was almost 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 smart.
As for the words of gratitude, Han Bin didn't say it, and he couldn't say it.
Parents' love for their children had become a common instinct.
If an outsider gave something good, it was very likely that the person would become a confidant.
Parents' love had 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 and chatted with his mother, grandfather, and uncle for a while. Then, he took the lunch upstairs to eat.
When he opened the lunch box, the food inside was still hot. It was very sumptuous. There were four dishes, one soup, and one bowl of rice.
The rice and soup each took up a layer, and the four dishes were divided into two layers.
At noon, Han Bin only ate casually. He was so hungry that his chest was sticking to his back.
In less than 20 minutes, Han Bin finished all the food and drank a bottle of iced cola.
Although the weather was cold now, it tasted better when it was chilled.
As long as the conditions were met, Han Bin was more particular about food and drink.
After the meal, Han Bin took a shower, lay on the bed, and read a novel for a while. Then, he went to sleep.
…
The next morning, Han Bin washed the lunch box and placed it at the door of his parents' house. Then, he took the breakfast from the doorknob and went to work.
In order to make it convenient for Han Bin to eat on the way, Wang Huifang made a roll. It was a freshly baked big roll with ham, bacon, fried eggs, lettuce, tomato slices, and a bag of hot milk. Not only did it taste good, but it was also nutritious.
When he reached the office, Ma Jingbo called everyone for a meeting to summarize the progress of yesterday's investigation.
Yesterday, Ma Jingbo brought people to Cheng 'an Village to make a statement on the employees of Fulong Feed Factory. He investigated all the local employees, but he didn't find any clues.
There were also two employees from other places who couldn't make it because the road was blocked.
Ma Jingbo decided to temporarily give up on the investigation of Fulong Feed Factory.
Investigation was a very complicated matter. Theory and practice were two different things.
Sometimes, solving a case also depended on probability and luck. He had to invest the limited police force to investigate the key clues.
Fulong Feed Factory was a suspect, but Ma Jingbo couldn't guarantee that he would be able to find the suspect if he followed this clue closely.
Yesterday, when he was investigating the case at Fulong Feed Factory, he found a lot of people watching the scene.
This made him think of another possibility. The suspect might not necessarily be the employees of the feed factory. When Zhang Jinlin and Old Liu hid or took out the keys, they might have been seen by passersby.
Thinking about it this way, the range of suspects was too big. Ma Jingbo didn't dare to continue to invest a lot of police force into the investigation.
The day before, Han Bin had called him to complain about the lack of manpower.
Thinking about this, Ma Jingbo couldn't help but ask, "Han Bin, what's the progress on your side of the investigation?"
Han Bin narrated the situation of the investigation and his analysis from beginning to end.
After listening, Ma Jingbo expressed his agreement. "Not bad, your analysis makes some sense. Since the two of them have something in common – looking for a job, let's start the investigation around this point."
"The investigation of the surveillance is also very important. Although the previous surveillance investigation didn't find any suspicious vehicles or people, there are two cases now, so we can cross-compare them. If the same car or the same person appears near the two crime scenes, then he is very suspicious. "
"I'll rearrange the task. The surveillance videos can't be checked separately, but by a fixed person. The surveillance videos of the two cases are checked separately by different people, so there's no cross-comparison. It's not very meaningful. "
Zeng Ping recommended himself. "Captain Ma, let me bring someone to check the surveillance videos."
"Sure." Ma Jingbo nodded. Just when he was about to speak again, there was a knock on the door.
"Knock knock …"
