Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 411 The roots are in the past

Ren Qiang's analysis was more specific than the speculation about vendetta raised during the case analysis meeting.

"Well, you go on."

"Vendetta, lumber mill, peeling, and why did the other party choose to do it in the Fangmu storage warehouse?"

"In the lumber factory, except for the dormitories, all the warehouses are empty in the middle of the night."

"Also, head, 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 where the square lumber is installed is relatively close to the gate for the convenience of transportation."

"However, the location where the murderer dragged Zhang Xiaofeng over the wall was actually the farthest away from the warehouse."

"why?"

"The place where the other party chooses to climb over the wall must not be a random choice. It is most likely carefully selected by the other party. First, they must try to avoid people who may encounter them, and second, they 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 if he chose to kill there?"

"So, I think the murderer must have a deeper intention in choosing the place to kill."

"Then what do you mean?"

"The investigation will focus on workers in the lumber factory, especially those who have resigned but had issues with Zhang Xiaofeng."

"Although the murderer only left footprints and no other clues at the scene, 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 conducted a survey of workers in the factory at the very beginning, but the focus was on existing workers. Workers who had resigned before were only asked for a list.

"I agree with this direction. If you need any resources, please report to me 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 is at the scene, immediately after the incident.

Yesterday, during the day.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 of the bigger clues have been closed now, making the case difficult to solve."

Lao Yang just made some inquiries and found out that neither Su Xiaogang nor Wang Qianqian was the murderer.

"Xiao Lu, have the results of the DNA identification analysis come out yet?"

"It's almost time. I didn't know if the hair I only found out about in the middle of the night yesterday was Zhang Xiaofeng's. If not, that would be great."

Lao Bai nodded: "I hope, I can't find it after questioning, but if there are DNA identification and 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 library, and that 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 had encountered a case before. After the incident, the entire 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.

Therefore, the criminal police officers handling the case collected DNA information from more than 10,000 people. 10,000+ people…

This is the horror of the murder case being solved.

A criminal suspect would never imagine how hard the police would go to solve a murder case.

"Whether he's in the library or not, it's better than nothing. By the way, do we still have to accompany the class today?"

"Then we must accompany you. The people in Group [-] and Group [-] didn't sleep much last night. It's okay for us to sleep in the office. If we go home..."

During the handling of the case, every piece of information reported to Qin Yong and 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 compile it.

Therefore, everyone seems to be following the steps, 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 must be done.

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.

There's no way, it's just luck.

Zhang Xiaofeng lost his hair at that time, but the murderer didn't. It was as simple as that.

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 next morning.

Ren Qiang, Zhang Hui and other elites from the second group have spent one night in the lumber factory.

Each of the 36 workers was interviewed, but what Ren Qiang didn't expect was that the first time these workers came to work was two years ago.

None of these workers knew about past events, such as which workers Zhang Xiaofeng had hired before, what disputes 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 guard had not been here long and was not very clear about the past: "I heard that Mr. Zhang's wife stayed here for a long time when he opened the factory. 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 something wrong with the recruitment time for 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 or so.

Logically speaking, Zhang Xiaofeng's lumber factory has been open for five years, so it shouldn't have no laborers, 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..."
