This almost caused the Criminal Investigation Brigade of Longxing District Branch to collapse. Why did you go there so early?

Generally speaking, when encountering this type of kidnapping case, the victim should call the police as soon as possible and let the police handle it.

However, there are also many victims who, under the threat of the kidnappers "not to call the police or else they will be killed", have compromised and just followed the kidnappers' demands like puppets on strings, giving money to the kidnappers and giving cars to the kidnappers.

When the kidnappers achieved their goal and released the hostages, you thought of calling the police.

Do you think the police are gods? Or do you think the kidnappers are idiots?

As long as the kidnapper is not stupid, he will definitely get away with it, and probably won't leave any clues for the police to solve, at least there won't be any obvious flaws.

Of course, these thoughts are only the private thoughts of some policemen in the Criminal Investigation Brigade who are handling the case. They must not be spoken out, and the case must be handled as soon as possible.

After all, the nature of this kind of kidnapping and ransom case is very bad.

But now nearly a week has passed, and they have put in countless efforts, but still got nothing.

The mobile phone card used was fake, the money withdrawn was cash, the hiding place was an abandoned building on the outskirts of the city, and the escape route was planned in advance...

The only thing that might be considered a flaw is that the kidnapped little girl had seen the suspect's appearance.

In the words of the little girl, the four people who kidnapped her were men, very tall, much taller than her, and older than her...

This is actually normal. If you ask a little girl who has just entered the second grade of elementary school to accurately describe the physical characteristics of the suspect, then the child will probably not have a headache in writing an essay.

And this was probably the main reason why Guo Tai seriously doubted that Mu Yuan could draw the suspect.

…

"Mr. Zhou, you talked to the kidnapper on the phone. Where does his accent come from?"

"He speaks Mandarin, but with a slight Northeastern accent."

"Little girl, let me draw some eyes for you. Which one do you think is more like the bad guy who captured you?"

"Um!"

"..."

"What about this nose? Is it similar to the bad guy in plaid clothes you mentioned?"

"Um!"

During the painting process, Qian Hongxian and Guo Tai kept watching.

They were at a loss when they arrived. They always felt that Mu Yuan's painting method was different from the painting methods they had been exposed to before, but they could not distinguish the advantages and disadvantages.

Qian Hongxian was not responsible for this kidnapping and extortion case, but because he was not sure whether Mu Yuan could really draw the suspect, he did not notify the captain who was directly responsible for the case.

But when the first painting was completed and the little girl shouted excitedly, "It's him! It's him!..." Qian Hongxian immediately picked up his cell phone and called the team leader.

Regardless of how high the similarity is, just by the little girl saying "that's him", we can judge that this portrait has a certain possibility of identification.

If the other three people drawn later also have the same degree of recognition, the possibility of finding out their identities will be much higher if the four portraits are put together.

By the time Zhang Huarong, captain of the Longxing District Criminal Investigation Brigade, rushed back from outside, Mu Yuan had already drawn two portraits.

But the little girl completely forgot that she was handling a case, her eyes were shining with stars, and she admired the big brother in front of her so much.

When Zhang Huarong walked in, he saw the portrait of Mu Yuan who was concentrating on it, and frowned slightly, but did not speak.

"Captain Zhang, look at that portrait!" Qian Hongxian pursed his lips towards the portrait placed on the table next to him.

Zhang Huarong followed the other person's eyes and looked over, his eyes froze for an instant.

He saw a lifelike portrait on his desk. If he hadn't known it in advance, he might have thought it wasn't a painting at all.

"What's going on?" Zhang Huarong looked confused.

Qian Hongxian called him just now and simply told him to find a good simulation artist and create a simulation portrait. The kidnapped girl said that the portrait was exactly the same as one of the kidnappers, and then...he

He just ran back in a hurry.

But now that I saw Mu Yuan's young face and that realistic and over-the-top portrait, I was completely mesmerized.

Qian Hongxian grinned and softly explained the cause and effect...

Zhang Huarong's face became extremely wonderful. Although he felt that what Qian Hongxian said was too exaggerated, the portrait that had been placed on his desk always dangled in front of his eyes.

At this moment, a footsteps came from the door.

Qian Hongxian hurriedly looked back and saw Fan Yitong walking in from outside.

"Brother Fan, are you here?"

Fan Yitong's eyes fell on Mu Yuan first, and he suddenly looked stunned.

"I was wondering why I didn't answer my call to Brother Yuan. It turns out he came here to take a portrait." Fan Yitong's tone revealed a strong sense of expectation, and his eyes were fixed on the pencil in Mu Yuan's hand.

"Brother Qian, you are lucky! If you can get Brother Yuan's portrait, your case will definitely be solved."

Qian Hongxian's eyes trembled. He felt that he had enough trust in Mu Yuan, but he didn't expect that Fan Yitong was the real fan.

Suddenly, Qian Hongxian's heart moved and he asked: "Brother Fan, I just chatted with Xiaomu and found out that he is proficient in simulation portrait technology. No, we happened to have a case here that fell into a dead end, so we had to ask Xiaomu to

Mu Yi is showing off his skills. To be honest, I don’t know what to do! The portrait Xiao Mu painted is really..."

Before he could finish speaking, Fan Yitong said, "Brother Qian, why are you thinking so much? Just take photos of these two portraits and then use facial recognition to see if you can identify the suspect."

Qian Hongxian's mood was very complicated.

In fact, he had just heard Mu Yuan talk about using simulated portraits and facial recognition to determine the identity of the suspect, but he simply listened to it as a story, not to mention the extent of its authenticity, even if it was a fact.

It's probably just luck.

But now seeing Fan Yitong's vow, he couldn't help but think again.

"Could it be that...simulated portraits can really be used for face recognition?"

Fortunately, this problem is not complicated. Although it is unbelievable, won't there be results if you try it? The police are a group that focuses on evidence, and practice will bring true knowledge. Anyway, it doesn't cost much to try.

Mu Yuan seemed not to have heard their conversation and continued to communicate with the little girl and his father. The portrait...

Qian Hongxian winked at Guo Tai, and the two of them took photos of the two already drawn portraits, and then imported the data into the face recognition system.

Soon, the feedback results came out.

Looking at the long list of personnel information, Qian Hongxian and Qian Hongxian were a little confused.

After all, they had never done this before, and some of them didn't know how to proceed.

However, as the team leader, Zhang Huarong reacted very quickly and immediately said: "You can find people with high similarities from the two sets of data, and do an analysis in the big data to see if there are any related people.

.”

"Okay!" Qian Hongxian's eyes lit up and he immediately did it.

Big data analysis is slower than face comparison...

But after all, it was only the data of more than twenty people, and the results were quickly analyzed.

Among the people identified in these two portraits, in one group there was only one person named Wang Hai who had recent activity tracks in Haibo City, but in the second group, no one had any data records in Haibo City.

.

One thing that is very gratifying is that one of the people in the second group has many records of traveling together with the person in the first group who has been active in Haibo City in recent years.

Although this cannot prove that the two people must know each other, at least the probability of knowing each other is quite high.

At this moment, Mu Yuan's third portrait was drawn again.

After placing it on the work desk, I saw that they were performing face recognition. I smiled shyly and said, "Let's recognize this one too."

After saying that, he ignored them and continued to draw the last person.

Qian Hongxian was stunned, and immediately followed Mu Yuan's request.

A few minutes later, Qian Hongxian and others were shocked to discover that one of the people identified through the third portrait was actually related to Wang Hai, and it was not an ordinary connection, but a record of staying in the hotel.

Uh, okay! Sharing a room in a hotel doesn't necessarily mean an abnormal relationship, but knowing each other is a sure thing.

After all, this is not a few decades ago, when staying in a hotel was charged by the bed...

Zhang Huarong took a deep look at Mu Yuan. He saw everything the little girl did just now. Mu Yuan finally finalized the portrait. The only criterion was that the little girl thought the portrait was exactly the same as the suspect in his memory.

Although children's memory may be biased, if four consecutive people are exactly the same, and at the same time, the people identified through the four portraits are all related to each other, this is worthy of discussion.

Three related people have been identified in the current three portraits. If the fourth portrait can also identify a person who is related to these three people, or has recent activities in Haibo City, then these four portraits

The credibility of the portrait is very high.

I don’t know if it’s because the first three portraits have made me familiar with the process, but the fourth portrait only took as long as the first portrait.

Mu Yuan touched the little girl's head and praised: "Xiao Miao, you are awesome!"

The little girl tilted her head and said, "My uncle painted it well! It was only after my uncle finished the painting that Miao Miao recognized it."

Mu Yuan paused for a moment, then pursed his lips and smiled: What kind of truth is this kid talking about?

Afterwards, Mu Yuan stopped chatting with the little girl and handed the portrait to Qian Hongxian, saying: "Captain Qian, let's try again."

Team Qian couldn't wait to take the portrait and did the same operation again.

A few minutes later, the new data was displayed in front of everyone. Everyone was shocked when they saw the person with a similarity of 97%.

Of course, the most surprised person was Xiaomiao’s father, Mr. Zhou.

This person's name is Zheng Xinsheng, which is normal, but in his personal information, there is an item about his work unit, called Hongkang Co., Ltd.
