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

Chapter 391 Three Photos
"Teacher Lu, thank you for your help this time. On behalf of the Huangzhou City Criminal Investigation Detachment, I thank you!"

Liao Junlong was really happy. He valued Lu Chuan. On the one hand, Lu Chuan was the murderer of Wu Qizhou's murder case. There were not many opportunities to meet experts of this level.

On the other hand, for this husband-murder case, I originally just had the idea of ​​giving it a try, but I didn't expect that the other party solved the case in less than 10 minutes.

And the fingerprints that he wanted the other party to help turned out to be deliberately left by the murderer to divert attention.

Footprints are the key to solving the case.

I have been a criminal police officer for so many years, so I have a lot of experience, but from a purely technical perspective, I really can't keep up with the pace.

"Captain Liao, you're welcome. Although the fingerprint is not easy to identify, I heard that the provincial department is already queuing up, and the results will be available in a week or two. By then, the skills will reveal that the fingerprint is actually that of the deceased."

"At that time, the attention of the case will naturally shift to the footprints."

Liao Junlong shook his head: "We have done our own on-site inspection and analysis of the footprints, but we have not come to your conclusion. We simply cannot find that the murderer wore shoes three sizes too big and deliberately left footprints, and even entered the scene upside down."

Lu Chuan said it was easy, but in fact, ordinary people couldn't do it.

The provincial department does have footprint identification experts, but to what level?
Liao Junlong felt that there might still be some gap compared with Lu Chuan.

It doesn't mean that the problem can be seen just by placing the footprints there.

They also saw the footprints, but did not report them to the provincial department for help in identifying them.

On the one hand, the waiting time is too long, and on the other hand, there are fingerprints.

There are fingerprints on the murder weapon, so why analyze the shoe prints?
Moreover, there is another possibility. The provincial department has not successfully analyzed the fingerprints with the identification, so the case may become unsolved.

"Anyway, it's thanks to you this time. I will be the host and treat my brother to dinner tonight."

There may be trouble in the future. No, there must be trouble with others. It is very necessary to build a good relationship and keep in touch.

After all, Huangzhou and Haizhou are far apart, not in the same province, and their connection is not close enough. It is basically impossible to get Lu Chuan to help through formal means.

But private relationships are much easier to handle.

The two drank tea and chatted about Huangzhou's customs and customs, and soon it was afternoon.

The investigation by Zhang Hui and others also has some clues.

The investigation of seventeen people has basically concluded.

In the conference room, Zhang Hui, Lu Chuan and others, as well as the criminal police involved in the investigation from the Huangzhou City Criminal Investigation Detachment, were having a meeting.

"Among these 17 people, I think the people who went to the bar together to drink and have fun can be eliminated as suspects first."

Although Zhang Lijun is from the Criminal Police Brigade, he has been following Wang Lili's disappearance case, so he also participated this time.

Zhang Lijun's judgment was recognized by most people, including Zhang Hui and Lu Chuan.

Lu Chuan had already read the records of the parties involved in the investigation. Among the people who went to the bar together, they could prove to each other that they all went home after playing.

In addition, if the other party lures Wang Lili to go to the chemical factory, the probability of going with others to play is very small.

In addition, Haizhou's investigation results on the disappearance of the second body, Su Xiaochen, were also sent to Zhang Hui.

Although there is currently no substantial evidence to prove when and where Su Xiaochen disappeared, according to the fact that Su Xiaochen often visited Slow Bar, KTV and other entertainment venues, combined with Wang Lili's disappearance, there is a high probability that Su Xiaochen disappeared in Slow Bar.

After all, the environment is noisier than bars, KTVs, and rocking bars, and it is easier for strangers to strike up a conversation and get to know each other. "The murderer is used to looking for prey in places like slow bars."

This is the behavioral judgment given by the Haizhou City Criminal Investigation Detachment.

Although it is still unknown how many people the murderer killed, from the analysis of the known life patterns of the two deceased people, there is a high probability that such a person can be concluded.

"Now among these 17 people, we have basically found people in Huangzhou City and conducted investigations. From the current point of view, there are no particularly big doubts. The key is that there are still three people."

Among the 17 people, the information of 10 people has been confirmed through consumption records. The remaining 7 people have also confirmed relevant information this morning. Four people in Huangzhou City have all done research, and there are three people from other places.

These three people are currently the focus of the investigation.

"These three people... can the surveillance side get photos of faces for comparison?"

"I've already seen it, it's only a profile photo, and it's not very clear."

Lu Chuan had studied these photos personally. The light was too dark and the definition was not high. The key was that only two of the people had only half of their faces, and one person had only the back of his head.

There was no way to determine the identity.

The case appears to have reached an impasse.

The investigation of these people in Huangzhou has been completed, and the remaining three are not in Huangzhou. Now it seems that it is very likely that the murderer is hidden among these three people.

Lu Chuan and Zhang Hui, who had no choice but to take three photos, boarded the plane back to Haizhou City.

"Brother Hui, just forget it?"

On the plane, Lu Chuan was still a little unwilling.

This time I came to Huangzhou, I certainly gained something, but it was not as big as Lu Chuan expected.

I thought that Wang Lili had always left more clues and could find clues about the murderer from the other party, but I didn't expect that I only got three unclear photos.

Lu Chuan himself had done image enhancement on the three photos, but unfortunately, there was no way to compare the half face and the back of the head.

Make bricks without straw.

Zhang Hui is not willing to give in, but there is no way, the reality is this.

"Actually, three photos are already very good. I have been working in the front line for so many years, and I am satisfied if I can achieve something like this."

This situation is the normal situation in the daily work of frontline detectives. After running around for a long time, there may be no clues.

But the technical detective is different. The job of the technical detective is 1 is 1 and 2 is 2. There is only yes and no, no intermediate state, no ambiguity.

For example, when Lu Chuan was doing fingerprint identification analysis, he could not come to a conclusion that proved that the fingerprints were both similar to this person and that person.

Others, such as DNA identification analysis, footprint analysis, etc., are similar situations.

The first-class treatment was not canceled because the clues in the case were unsatisfactory. In Lu Chuan's words, the case was not solved yet, so he had to show some sympathy to himself.

The pressure on your mind is already so great, so don’t let your body suffer too.

Zhang Hui said it would be great if detachment leader Qin Yong could think like Lu Chuan.
