Chapter 411 The root lies in the past
Ren Qiang’s analysis is more specific than the speculation about vendetta put forward during the case analysis meeting.
"Well, go on."
"Vendetta, lumber mill, peeling, and why did the other party choose to do it in the storage warehouse of square wood?"
"In the lumber factory, except for the dormitories, all the warehouses are empty in the middle of the night."
"Also, head, take a look at this."
Ren Qiang picked up the pen and paper on the table: "This is the schematic diagram of the factory building in the lumber factory. The warehouse for installing square lumber is closer to the gate for the convenience of transportation. "
"But the location where the murderer dragged Zhang Xiaofeng over the wall was actually the farthest away from the warehouse."
"Why?"
"The other party chose. The place to climb over the wall must not be chosen randomly. It is most likely carefully selected by the other party. First, you must try to avoid people you may encounter, and second, you must ensure that there are no nail boards inside the wall.”

"After the murderer chose this crossing point, the warehouse on the left is used to store scraps. No one usually comes here. Wouldn't it be safer for him to choose to kill there?"
"So, I think the murderer The choice of the killing place must have a deeper purpose."
"What do you mean?"
"Focus on the workers in the lumber factory, especially those who have resigned, but with Zhang Xiaofeng. There are workers who are having trouble.”
“Although the murderer only left footprints at the scene and no other clues, the entire process of his crime revealed that he was very familiar with the lumber mill.”
"This is definitely not something that can be figured out by just staying in the factory for a day or two."
This analysis...
It is indeed a direction. In fact, the second action team was at the very beginning At that time, we conducted a survey of workers in the factory, but the focus was on existing workers. Workers who had resigned before were only asked for a list.
"I agree with this direction. Please report to me any resources needed at any time."
"Yes!"
The action team is working hard to advance the case, but the scene in the investigation office is in a different state.
Lao Bai was half lying on the sofa: "Lao Yang, how is the case over there?"
The current investigation work was at the scene, immediately after the incident.
It was daytime yesterday. In one night, they had done everything they could.
The analysis and identification of the footprints identified the suspect's physical characteristics, which is the biggest contribution of the current investigation.
"I'm still working on it, but I heard that two major clues have been broken now, and the case is difficult to solve."
Lao Yang just made some inquiries and found out that neither Su Xiaogang nor Wang Qianqian was the murderer.
"Have the results of the DNA identification analysis come out yet on Xiao Lu's side?"
"It's almost time. I only found out about the hair in the middle of the night yesterday. I don't know if it belongs to Zhang Xiaofeng. If not, that would be great."
Lao Bai nodded: "I hope, if the questioning doesn't find it, but there are DNA analysis results, then maybe the case will be solved directly."
"That's true, but I'm afraid that the murderer's DNA information is not in the database, which would be troublesome."
The data in the DNA information database is unlikely to include everyone's data.
Compared with fingerprint collection, which is simple and widely used, the process of DNA information identification is cumbersome and takes a long time. In terms of convenience in handling cases, fingerprints are obviously more widely used.
DNA comparison is often used when the suspect has been roughly identified.
Lao Bai has encountered a case before. After the incident, the whole town was sealed off. The murderer must be in the town.
Nothing else was found at the crime scene, but there was a hair from the murderer.
So, the criminal police who handled the case collected DNA information from hundreds of thousands of people. Hundreds of thousands of people...
This is the horror of the murder case being solved.
Criminal suspects will never imagine how desperate the police will go to solve a murder case.
"Whether you are in the library or not, having it is better than not having it. By the way, do we still have to accompany the class today?"
"Then we must accompany you. The people in the first and second groups did nothing last night. Let’s just sleep in the office. If we go home..."
During the case handling process, every piece of information reported to Qin Yong or even Ren Qiang was not obtained out of thin air.
A video of several hours can cost one person, and one person’s background information may require that person to work overtime all night to complete it.
So, everyone seems to be doing the work step by step, but in fact they are very busy. This busyness may not necessarily help solve the case, but it is very important to eliminate the selection. It is cumbersome and has a low sense of value, but it is necessary. Do.
For others, at this time, it is necessary to accompany you to work overtime. Everyone forces you, but you will do it consciously.
There is no way to go back to the forensic department. All the lesbians in the office are living in the dormitory. Who dares to leave at this time?
“Brother Bai, what are you talking about?”
Just as he said this, Lu Chuan completed the hair DNA information identification, and the results came out.
"It's okay, it's just about the case. How are you doing?"
Current surveys may not be able to turn the tide every time.
At least this time, Lu Chuan didn't make any big discoveries.
“The hair found under the wall belongs to Zhang Xiaofeng.”
Lao Bai was stunned, and Lao Yang sighed.
No way, this is luck.
Zhang Xiaofeng lost his hair at that time, but the murderer didn't, it's that simple.
If it was dropped by the murderer, it would be so simple and a matter of probability.
Liu Guodong has reported the relevant results to Qin Yong.
Time passed quickly and it was the morning of the next day.
The elites of Group 2, including Ren Qiang and Zhang Hui, have spent one night in the lumber factory.
Each of the thirty-six workers had a conversation, but what Ren Qiang didn't expect was that the first time these workers came to work was two years ago.
These workers don’t know anything about past events, such as which workers Zhang Xiaofeng hired before, what conflicts they had with each other, and whether anyone had any conflicts with Zhang Xiaofeng.
"This matter... I think you can ask Mr. Zhang's wife."
The doorman has not been here long and is not very clear about the past: "I heard that Mr. Zhang The president’s wife stayed here for a long time when he opened the factory, and she must be familiar with the past things.”
In the afternoon, after summarizing the information, Zhang Hui was keenly aware of the problem.
"Brother Qiang, there is a problem with the recruitment time of workers here."
Ren Qiang also discovered that some of the existing workers in the lumber factory were recruited two years ago, and some were recruited in the past year. Recruiting more.
It stands to reason that since Zhang Xiaofeng’s lumber factory has been open for five years, it shouldn’t have no workers at all, right?
So, what is the reason that makes all the old workers leave?
An hour later, Ren Qiang and Zhang Hui met Zhang Xiaofeng’s wife.
When asked why there were no old workers, Zhang Xiaofeng's wife's expression suddenly changed.
"This...what happened that day...is so embarrassing, I..."
