A person is most likely to forget inadvertent things, but the things that impress people at the time may not be forgotten after a long time. Liu Jia asked the drunk if anything unpleasant had happened to him, which was based on the characteristics of the drunk who would not lose consciousness when he was drunk, and would go crazy drunk.

Being conscious ensures that the drunk may remember the basis of the consciousness of what he saw or happened at that time, and will go crazy, which will put the drunk in an extremely easy way to get angry, or see nothing that is not pleasing to the eye. In this way, it is likely that a small thing will make the drunk feel uncomfortable and thus remember.

This is what Liu Jia asked: unpleasant things.

Hypnosis belongs to psychology, or has an intersection with psychology, and I suddenly found that Liu Jia has become a little more mature. She no longer uses simple hypnotic methods, but completely integrates hypnotic methods with psychology and applies them to all levels.

All of a sudden, I saw Dr. Liu's shadow on Liu Jia's figure. Give her time, maybe it won't be long before Liu Jia surpasses Dr. Liu and becomes another Dr. Liu of the Police Academy, famous all over the country. It's just that Dr. Liu's shadow disappeared quickly, and I was worried about Liu Jia's safety.

I don't want Liu Jia to die in the actions of our task force.

was asked by Liu Jia, and the drunk immediately recalled it carefully. We all set our eyes on the drunkard, and finally found a potential witness, if he didn't know anything, the woman in red serial murder case may be over, and no clues can be found to solve the case.

He's almost our last hope.

While we all waited anxiously, the drunkard finally spoke, and said that one night, when he came home, he walked and rested, and was drunk more than usual, so that he walked longer than usual. And on the road, the drunk man crashed into a garbage truck.

It was a street sweeper wearing a hat, tattered clothes and rain boots, and the sweeper was pushing a stinking garbage truck forward. The drunk was so drunk that he couldn't get out of the way, so he crashed into it in a daze, and the drunk said that he was very angry, and he scolded the street cleaner and punched him twice in the head.

When Shen Cheng heard the words of the garbage cart, he couldn't hold it anymore, and he asked, "That cleaner, what is your reaction?" ”

The drunk man thought for a while: "I can't remember clearly, it seems that I have been standing, I have been lowering my head, I haven't said a word, I haven't left immediately, I look quite tall, I can't see my face clearly." ”

After Shen Cheng listened, he immediately rushed out, and Liu Jia asked a few more questions, but the drunk couldn't answer. The drunk man said he was so angry partly because he was drunk and partly because the garbage truck was so smelly.

Unable to ask anything, the police let the drunk go back for the time being.

And half an hour later, Shen Cheng came back sweating profusely, and I asked Shen Cheng how it was, and Shen Cheng said that the street cleaner might be the murderer. The street cleaners are hired by the neighborhood committees and the neighborhood department at low salaries, and the wages are very low, and they are usually elderly people who have no other life skills, and they live on the low wages of the neighborhood department and the sale of bottles and cans.

Each street cleaner will sweep a block, because there are many people during the day, in order not to affect the block, the sweepers go out to sweep the floor late at night or early in the morning. Shen Cheng found the cleanup in charge of that street, and the cleaner said that he was assigned to that block because the previous cleanup worker was sick and died.

Shen Cheng found that the new clean-up workers took up their posts a few days after the headless female corpse was found. Shen Cheng found the street department, and through the street department, he found the home of the original cleaner. When asked about the specific situation, Shen Cheng had basically determined that the cleaner that the drunk man bumped into was the murderer.

Because, before the cleaner died, he was sick for a few days, and the illness was very sudden, and he couldn't even speak for a few days when he was sick, and in this state, he naturally couldn't sweep the floor. Shen Cheng asked the old man's family, and they said that they were so worried that they didn't bother to notify the street department at all, and they didn't let anyone else sweep the neighborhood on their behalf.

In order to further confirm, Shen Cheng also managed to ask all the street cleaners in the vicinity of that area, and found that no one cleaned the cleaner at all. In other words, a day or two before Rena's body was found, that block should have been cleaned by no one.

This kind of dirty work, if no one pays a salary, it is absolutely impossible to push a garbage truck to clean, even if it is a volunteer, it is impossible to sweep the floor alone in the middle of the night, and he is dressed exactly like a cleaner.

"There is definitely something wrong with the cleaner that the drunk man bumped into, the sweepers in that block are all old people, with their bodies on their backs, and their height is not high, but the drunk man said that the people he saw were relatively tall." Shen Cheng's expression was solemn: "Moreover, an ordinary old man, where can he afford a drunk man to punch him twice in the head, even if he is not knocked to the ground, he will be frightened and hurry away." But the drunk man said, the man kept his head down, and he didn't mean to leave, Liu Jia, what did you say about that person, what was he thinking at the time. ”

Liu Jia thought for a while and replied: "It's not like he's afraid, if he's afraid, he won't say a word, and he still stands in place, he should be angry, perhaps, he was already murderous at that time, but if he killed someone on the street, it would cause more trouble, so he was hesitating." ”

Shen Cheng nodded: "It should be a young man or middle-aged person, looking at his height, he is a man, his real personality should be relatively cold, so after colliding with a drunk, he will stand there for so long." Shen Cheng said, and asked Tang Yingxuan to bring all the files of the woman in red case, and he turned over all the photos of the corpses in every case since 1988.

I have seen these photos more than once, and Shen Cheng said that through these photos, the character of the murderer may be more certain. What Shen Cheng said comes from the concept of criminal psychological portrait, which refers to the character of the murderer inferred by the police based on some details of the crime scene.

When the murderer commits a crime, he often deliberately or inadvertently leaves some clues, which can indicate the character and characteristics of the murderer, which is the criminal psychological portrait.

"Look at this one, the arm was amputated, but the wound was very neat, it was cut with a sharp weapon." Shen Cheng said, pointing to a photo: "There is also this one, the thigh was dismembered, but the wound was unfair, the flesh and blood were blurred, and it was cut open by a blunt object." ”

Soon, we found that in these cases, the wounds of the corpses were not regular, some of the wounds were very neat, like a one-size-fits-all cut, and some of them were very blurry, especially the neck of the headless female corpse Rena, and even the trachea and bones were cut off.

"I don't think that the murderer left different traces of corpse wounds because of the limited tools of the crime, he must have thought about how to kill the victim for so long, and the tools were naturally prepared. He did it on purpose, sometimes with sharp objects, sometimes with blunt objects, and did not have severe obsessive-compulsive disorder. Shen Cheng said to me.

Shen Cheng's speculation can be regarded as a negation of my earliest inference. At that time, I saw that these organs were about to be able to form a person, and I thought that the murderer had severe paranoid obsessive-compulsive disorder, but a person with such obsessive-compulsive disorder, when doing great things, would never tolerate such a big difference in each wound.

"It is even said that the character trait of the murderer is a very unruly person!" Shen Cheng said.

Liu Jia used psychological questioning to completely open everyone's minds, although we don't know who the murderer is, but we have already speculated about the murderer's personality traits.

"An unruly person, but he also wants to piece together a person's actions, Li Ke, what do you think such a person will do?" Shen Cheng asked me suddenly.

I frowned, and at this time, Shen Nuo suddenly said: "I have a guess, I don't know if it's right." ”
