Detective: I have a split personality, but I’m really not a murderer

Chaoyang Investigation Bureau!

After the technicians obtained the video of the suspect, they immediately repaired and identified the footage.

Almost an hour later, they contacted Sun Changming

"Director, after we repaired the suspect's appearance, we compared it with the criminal database.

But the match could not be completed! Sun

Changming frowned:

"That is to say, the suspect does not have any criminal record?!"

"That's right!"

The technician continued:

"Next, we have two ideas.

One is to obtain facial scan data of passengers at Dajing bus station, train station, airport, etc. for comparison.

This requires your approval!

Then again!

You can send several teams to investigate where the suspect may be.

What do you think?"

"No problem, I'll arrange it right away!"

After Sun Changming completed the relevant matters, he immediately contacted Gao Ting and asked him to wait.

In the personality hall!

Guan Hongyu said in surprise:

"Well, with the suspect's photo, why is it so difficult to confirm her identity?

According to 253, the suspect must have applied for an ID card, and there should be photos in the corresponding system.

The image of the suspect outside the concert venue is entered into the system for comparison.

Can't you confirm your identity directly?"

"No way!

Brother, you take this for granted!"

White Night God Detective Guan Hongfeng looked at Guan Hongyu and explained:

"The core of the method you mentioned is facial recognition.

In many movies and TV dramas, as long as investigators have a photo of a person's appearance, they can perform facial recognition on the computer through surveillance, identity systems, etc., and lock the target's location and identity.

This actually exaggerates the ability of facial recognition!

The principle of facial recognition is that each person's facial features are specific enough!

The principles of fingerprint identification and DNA identification are actually the same.

The core of this type of identification technique is naturally to record and compare this specificity.

This cannot be done by just looking at it with the naked eye or scanning it casually with a machine.

Just talk about facial recognition!

We now have photos of the suspect from multiple angles. By summarizing these photos, we can basically grasp the specificity of her appearance.

But the problem is!

For some reasons, even fingerprints and DNA have not established a complete citizen database. Only criminals, missing persons and other special persons have established databases.

There is no corresponding database for facial features.

As for what you said, the photos in the citizen ID card system are not of much use.

Because to fully describe a person's facial features, not only do you need photos from multiple angles, but you also need to identify many feature points in the appearance.

This is not available in the ID card system. to be honest!

Even if technicians require it, facial scan information from bus stations and other places is often not enough to serve as a basis for matching."

"That’s right! Guan

Hongyu suddenly realized:

"I thought that as long as I got a photo of a person and confirmed his or her identity, it would be easy!"

Sheriff Black Cat:

"For the most part, it's really simple.

For example, if you post a photo of a suspect online, you will be able to get clues soon.

But the other party is a murderer after all, and a serial killer.

We must not only avoid alerting others, but also avoid jumping over the wall in a hurry.

It’s better not to issue a bounty directly until there is no other way."

Feng Yuxiu was obviously impatient:

"Now what?

Passenger data at stations and airports may not be valid.

Even if it is effective, the suspect may not have been to these places.

(cgaa) It is time-consuming and labor-intensive to investigate places where suspects may be.

In other words, in a short period of time, the suspect's identity may not be confirmed and the arrest cannot be completed?"

"Not so pessimistic!

Having the suspect's image data is equivalent to mastering Wang Zhao.

Catching him is just a question! (To read Baoshuang novels, go to Feilu Novel Network!)

Of course, the specific search methods must be carefully considered."

High Court thought for a while:

"Judging from the results of the criminal profiling of the murderer that we have previously obtained.

The murderer's temperament, hobbies, etc. may all be weird.

This may cause her to be withdrawn and withdrawn from others!

But even if we live in isolation, we must still have basic living needs such as food, clothing, housing and transportation.

Among them, the most essential thing is food!"

Highgarden said, Holmes added:

"The murderer's economic situation should be average, at least without independent income.

Because we have analyzed it before, judging from the murderer’s dissection technique!

Either she is studying to be a nurse!

Otherwise, he has dropped out of school!

Both situations mean she has no regular job.

It’s impossible to order takeout or eat out every day.

If she was studying medicine, it would be impossible to go to the cafeteria.

Because according to the requirements for refining zombies, she needs to go to the Crow Mountain from time to time to sprinkle quicklime, crow blood, etc.

It was therefore impossible for her to remain in school.

I even suspected that she might not live on campus.

Because Deng Ling temporarily escaped from the murderer's control, it means that the murderer has a foothold in the mountains and forests west of the moat. therefore!

Even if the murderer was a medical student, he would often need to stay upstream from where Deng Ling fell into the water to get food and drinks done.

She would either go to a cheap restaurant!

Or buy and cook your own food!

It would be even easier if the murderer dropped out of school!

The probability of her buying and cooking her own food is higher!"

Hannibal nodded:

"Therefore, in order to identify the murderer, it is best to search the surveillance cameras near the place where Deng Ling fell into the water, in wet markets or supermarkets.

There are also cheap restaurants worth investigating!"

The Riddler:

"The murderer probably doesn't have a car. You can also search the surveillance cameras near the bus station!"

……

During the personality discussion, the investigation ideas quickly took shape.

The High Court immediately extracted the surveillance of wet markets, supermarkets, etc. in specific areas and shared them for everyone to view.

He originally thought that the search would take a long time.

But less than half an hour later, Di Renjie, who had always been steady, suddenly said excitedly:

"found it!

I think I found the murderer!

Look at this meat buyer, is he a suspect?".
