Because of the follow-up reaction of the fifth positive, Ding Hua, who once again had a new understanding in his heart, left with the notebook evidence, and it seemed that he really had nothing to do with the fifth positive.

Just like this notebook passed down by the criminal syndicate, the meaning contained in it is closely related to the Fifth Positive, but before it is truly spoken, it has nothing to do with the Fifth Positive at all, only related to the Fifth Positive's associative ability, and related to the current focus of the Fifth Positive.

In this atmosphere of becoming anxious again, time reappeared in a binary entanglement that was both long and short, and the fifth Zheng, who was a little distraught behind a pile of dossiers, ran directly to the part that Huang Xia was responsible for, wanting to personally ask for information about the little boy who sent the letter.

After all, under the current situation, even if there is all kinds of relevant information about the suspect who sent the letter, it is extremely difficult to break through, and the fifth positive can only try it first.

At this time, the parents of the little boy had come to the public security bureau, and they seemed to be apprehensive about the child's loss, but they were also a little irritable and puzzled by the police's refusal to let go.

"We still have something to do at home, officer, you just let us go back first, if your police need it, we can cooperate with your police to do a follow-up investigation."

Children's time is not valuable, but we adults are busy with each other, and everyone is here to delay each other's time, you see how bad it is. ”

Although the boy's father's words were a little polite, there was already a hint of impatience in his tone, and if they were really allowed to leave, it might be difficult to get their sincere cooperation even if the relevant investigating police officers came to the door in person.

Sometimes, people just remember to eat and not remember, for other people's help seems to be taken for granted, for their own responsibilities and appear very indifferent, from the point of view that the boy will be deceived by strangers, the boy's parents usually control their children is the culmination of this indifferent characteristic.

"This gentleman, we still need your cooperation, otherwise if the traffickers come again next time, it may be too late to regret it."

For this kind of person, the easiest way is to kidnap him with the pain points he cares about the most, so that he does not dare to despise the current temporarily useless social relationships.

Hearing this persuasion of the fifth positive, the boy's father's expression was also immediately stunned, and he seemed to really realize the inappropriateness of his current behavior, if his child was really lost that day, he would eventually have to trouble the police in front of him to help find it.

But when he turned his head to look at the Fifth Positive and found that it was a young policeman who interjected, he immediately showed a little contempt for the Fifth Positive when he doubted the authority of the Fifth Positive.

The meaning of this expression could not be more obvious, just a little policeman, what if I offend you? Is this kind of work like finding someone not something that your leader said a word about?

"Your child is involved in two previous public terrorism cases and needs to be questioned and investigated by our police.

I am the leader of this task force, and with the authorization of the provincial department, I can temporarily mobilize the strength of the entire L City Bureau to fully investigate these two terrorist cases. ”

In the face of this kind of ordinary person who completely writes his emotions on his face, the fifth Zheng, who is already irritable and abnormal, has no leisure to entangle with him at all, and pinched his weakness between words, so that he can't regain the slightest contempt and neglect.

The deterrent effect of the fifth Zheng's words is indeed very good, and when he heard that his son was related to the previous two violent and terrorist cases, the man in front of him instinctively trembled.

If it is not handled well, for them ordinary people, it will be the end of their families.

The man, who was already a little afraid of this, heard again that the fifth positive was actually the leader of the task force of this case, and even at this time, he was able to command the security force of the entire city bureau, and the fifth positive with such a strong background seemed to know how to face it with his toes.

He is in an extremely unfavorable environment, and the young man in front of him is an absolute leader who can determine his life and death with one word, and it is impossible for you to say that this young father is not afraid.

"The sheriff is young and promising, and he will definitely be able to catch all the criminals as soon as possible and restore peace to our L city.

My son is actually fine, kindergarten is not a must, and it is very easy to take two days off, and we will fully cooperate with the police officers and fulfill our obligations as law-abiding citizens. ”

In the case of an instant change in mood, the young father, whose momentum was more than a notch lower, instantly exhausted what he had learned all his life and expressed his willingness to cooperate.

The internal police who were a little annoyed by the young father's entanglement before, at this time, when they saw the fifth positive, they got rid of this thorn, and instantly felt refreshed, and their eyes at the fifth positive were also a little more admiring.

On the fifth day, it really lived up to its name.

After a while, Huang Xia, who was organizing people to desperately review the video of the last disappearance of the little boy, also rushed over, and saw that the fifth was asking the little boy in person, and he was also very curious about it.

Could it be that the Fifth Zheng has found some other shortcut to the south?

"Kid, my uncle asked you a few questions and answered that not only do you have lollipops to eat, but you can also buy you all kinds of snacks to eat."

"Did the person who gave you the lollipop wear a mask?"

"Is the collar of the dress high?"

"Do you wear a hat or not?"

"Uncle or brother?"

"Were you wearing gloves?"

"What color is the overall outfit to wear?"

"What color are the pants?"

For this kind of little kid who can run after a lollipop, if you want to make him concentrate, then you must give him a reward that is more exciting than a lollipop.

Under the temptation of the fifth positive heavy reward, the eyes of the little boy, who was originally a little boring, instantly lit up, and it felt like it was about to be the New Year.

Children's potential is unlimited, and their memory is better than everyone expected, but because of the method and motivation of recall, it will seem that children will forget everything they see.

As a very simple example, if you hide what your child likes to eat out of his reach, anyone will be ashamed of his child's level of intelligence and perseverance.

Reward has always been the most essential motivation for human beings to engage in boring memories and boring repetitions, and this biological nature will only be more obvious in children.

And in the process of questioning, the fifth positive did not make any requirements for the correctness of the answers, but only asked him to answer these questions.

In this way, the child's response will be the most accurate first image, and the first overall effect he will have when he meets the criminal member, that is, the child's best image memory ability.

Under the fifth positive quick question, the child's answer also seemed very enthusiastic, and the answer was also very fast, and after this arrangement, it was finally revealed that the member of the criminal group only used a turtleneck jacket and hat to partially cover his facial features.

He was uncle-level, wore gloves, and the color of his shirt was gray and his pants were blue.

After the child happily answered the question, the fifth was gesturing to the stunned young father with his eyes, and motioned for him to buy snacks for his child.

The young father was a little unhappy, but when he thought of the identity of the fifth positive and the drastic methods of the fifth positive, he could only admit that he was soft and used his own money to pay for the promise of the fifth positive.

In the face of such quick questions and quick answers, it seems that a lot of information has been asked, but in fact, there is no use at all, first of all, this set of makeup is worn in an unmonitored location, after sending the little boy away, judging from the characteristics of Zhang Yun's many changes of clothes, it will inevitably show completely different clothing characteristics when he passes through the first monitoring point.

Even if it is more daring, it faces the surveillance with normal facial features, in order to completely drown out its whereabouts through the flow of people.

Among the pieces of information, there is only one thing that is useful, and that is the clothing of the members of the crime.

Judging from the characteristics of its high-necked coat, it is impossible to wear the upper body short, which is not only conducive to the initial disguise, but also conducive to hiding more other clothing accessories.

From the analysis of the characteristics of the cameras that the criminal members need to go through repeatedly, the optimal way to camouflage is to pass through the cameras in the process of a complete set of ordinary clothing, and only when luring the little boy, they can wear a set of disguises that the little boy roughly describes.

In general, a person's pants are the most difficult to change, and the offender is either wearing a pair of pants that can be easily put on and taken off through the zipper on the outside of the thigh, or the pants have not changed at all times.

In both cases, there are their own flaws, and the former only needs to look for an abandoned pair of pants at the point where the little boy originally disappeared.

The latter is much easier, focusing on sifting through passers-by in blue pants.

"Huang Group, what progress has you made in checking the video inspection work you are responsible for?"

Before arranging the follow-up tasks, the Fifth Zheng naturally needed to ask Huang Xia about their video viewing progress in advance.

"We had asked the boy some questions, but because he was not cooperative, we could only learn from his father about his eventual disappearance.

With this information, we transferred some of the nearby street shop monitoring and intersection monitoring to check some of them.

It's just that due to the fact that the flow of people in the area is really huge, we have not found any suspects who deliberately obscured their facial features. ”

Regarding the fifth positive move of being able to instantly extract the due information from the little boy's mouth through a reward, Huang Xia only habitually admired it at this time, and he was already thinking about the problem from the perspective of the fifth positive.
