At this time, the leader said: "Rest for ten minutes, you should go to the toilet, clear your mind, and come back in a while to continue!" ”

As soon as the leader's words were finished, Dalong didn't care whether Zhou Wang went to the toilet or not, and pulled Zhou Wang to go out the door.

The two of them walked out of the conference room, Zhou Wang broke free from the clutches of the big dragon, and asked in a low voice, "Do you know where the bathroom is?" ”

"I don't know, I can ask! Eh, have you noticed that what the psychology expert said is particularly right at first glance, but after careful consideration, it seems that he didn't say anything, just his last sentence......

Zhou Wang glanced at Da Long, Da Long paused, changed his expression and said, "I feel like the mouth is suddenly open!" ”

"Are you sure it's not the latrine thatching open?" Tong Sheng asked teasingly.

Dalong turned around and asked slightly embarrassed, "Teacher...... Also go to the toilet? ”

Tong Sheng laughed and said, "How can people eat grains without reincarnation?" Do you think I'm talking nonsense again? ”

Dalong was even more embarrassed, and he hurriedly explained: "Actually, I mean ......"

"Look, your sentence is also nonsense, let's go to the toilet together." Tong Sheng patted Dalong, looked at Zhou Wang again, and asked as he walked, "Have you read some books on psychology?" ”

Zhou Wang hurriedly waved his hand and said, "I want to see, I don't have time." ”

"Oh, I'll send you two books when you go back, you can read them when you have time, it's not all nonsense, there are a lot of things that can be used in the process of detecting the eucalyptus, such as the sentence I said just now, if the murderer is not a vendetta, he doesn't even know the deceased, this kind of serial eucalyptus, the victim selected by the murderer must be something that matches his heart, such as the color of the clothes, the characteristics of his appearance, the habitual movements between gestures, etc., there are places that stimulate the murderer, and this serial murder eucalyptus, may have to add family ......"

"Are you saying that the killer has the opportunity to learn about the victim's privacy before identifying the target?" Zhou Wang stood still.

Dalong hurriedly said: "This is very difficult, now all kinds of application software are allowed to fill in personal information when registering, how can this be checked?" ”

Tong Sheng said: "I just told Haitao that the families of the three victims must have some similarities......

"There are parents, mothers and children, which is no different from a person with a nose, eyes and ears, and the streets are like this." Dalong interrupted Tong Sheng and said.

Zhou Wang frowned and glanced at Da Long, who realized that he was not very polite, and hurriedly said, "I'll shut up." ”

Zhou Wang said:

"I firmly believe that the murderer has the opportunity to meet the three victims, and has the ability to know the addresses of the three victims, and what is even more terrifying is that he is very likely to meet more children who meet his standards through this ability!"

Tong Sheng nodded and said, "Therefore, it is very important to find the characteristics of the murderer's occupation or life to narrow down the scope of investigation." ”

……

Several people returned to the conference room after going to the toilet, and Chen Haitao had already written several characteristics of the murderer on the clipboard, except for the leader and Hu Yang, everyone else stood in front of the clipboard, adding bricks and tiles to the characteristics of the murderer.

The characteristics of the murderer's occupation written by Chen Haitao are: first, he can contact many children, second, he can know the children's home address, and third, the working hours are relatively fixed.

Dalong said, leaning on the clipboard, "It looks like a kindergarten teacher." ”

Tong Sheng said: "I have to continue to write so that he can show his true colors." ”

Zhou Wang said: "I can get a controlled narcotic similar to ether. ”

Lao Lu said: "Now it is impossible to determine whether the child was stunned before his death, since he is not sure, is it easy to deviate if he adds it?" ”

Dalong said: "I can't be completely sure of the first three points. ”

Zhou Wang explained:

"If the child is not stunned, the murderer will put scotch tape on the victim, unless after the victim's death, the murderer has a sense of ritual in his heart, so he put scotch tape on the child's mouth, but this process takes time, although it is not much, but it will increase the risk of being discovered, if it is tape in the process of making eucalyptus, I said that the child has a long mouth and legs, and he will run if he does not shout, the murderer did not bind the victim in any way, and the process of sticking is difficult to complete with one hand."

"What if scotch tape is a perverted manifestation of the murderer? You can't do this kind of thing without changing your mind! Regardless of how he did it, this possibility still exists. Lao Lu asked.

"Since it's all possible, you can't just write it down because you're not sure, you have to go down." Zhou Wang said with a smile.

Chen Haitao did not hesitate, and wrote the opportunity to get an anesthetic and some kind of strange belief in his heart in the fourth point.

Zhou Wang said again:

"Ether-based inhalable anesthetics themselves have a pungent odor and are easy to volatile, if the murderer wants to stun the child in this way, he must first seal the prepared ether-soaked handkerchief in the bag, otherwise the smell, he wants to approach the child from behind, and the child will instinctively look around when he smells the smell, not to mention that if he waits for a long time, the ether will have volatilized long ago, and then there is a period of time for the ether to enter the body to play a role, and the ether with higher purity, It also takes two or three minutes to cover the other person's mouth and nose to take effect, but adults generally do not obey, will struggle, will hold their breath, and in this process, ether may have volatilized. ”

"Why didn't I understand what you said? Are you saying that the killer used ether or was it useless? Lao Lu asked.

"I want to say that what is staged on TV is a lie, unless it is a child, otherwise use ether to stun adults, the chance of success is very small, children do not know how to hold their breath, it is very easy to be tricked! In addition to this method, what can be effective is the injection of anesthetic, which can be ruled out, because there is no pinhole on the child's body, if the murderer is using an inhalable anesthetic, then he needs to carry a sealed bag containing an ether cloth in addition to scotch tape, fruit knife, rope, and in order to prevent himself from being smoked, he will most likely wear a medical mask. ”

Chen Haitao muttered: "The murderer works in the hospital? ”

"Wait a minute!" Lao Lu said: "This assumption is based on the murderer's use of anesthetics such as ether, what if it doesn't work? ”

Zhou Wang said:

"If it doesn't work, you have to be able to make sense, how did the murderer put scotch tape on the victim? This goes back to the old way, but I have a little insistence, if the murderer has some kind of evil faith, then he doesn't need to be cruel step by step, the evil faith is enough to make him able to get down as soon as he comes up, or the murderer needs some sense of ritual, then the dead should be a way to die, but the part of the injury may be different. ”

"Doesn't the fact that there is a car next to each victim mean that it is a sense of ritual?" Li Jianhong asked.

Tong Sheng immediately said: "This can't be said to be a sense of ceremony, it is the murderer's own love for the child, as for which child he loves...... Tong Sheng frowned and paused and asked: "The three cars are all different colors, do you know whether this kind of car is bought separately or in sets?" ”
