The 24-hour deadline to solve the case is not only an order, but also a responsibility on the shoulders of the criminal police.

In the office of the Criminal Police Team, the case analysis meeting continues.

"This time the body was dumped at an abandoned construction site, which is not a gathering place for stray dogs. The murderer's throwing of the corpse, whether in terms of the time, location, and number of corpses, does not conform to the murderer's habit of throwing corpses in the first two times. Su Simeng analyzed seriously.

After speaking, he added: "But this time the body is dumped, and it is more certain that the murderer's vehicle is a small electric tricycle." If the killer had used an electric motorcycle and a bicycle, it would have been impossible to carry so many body bags at one time. ”

Ling Zizhen nodded, echoed and said, "That's right, the corpse pieces this time are even longer than the corpse pieces of the previous two times combined, and each bag will have more than ten catties." Moreover, the body parts thrown this time were not as broken as previously found, the edges were not neat, and the size was inconsistent. In general, the murderer was in a hurry to dispose of the body pieces. ”

As soon as the two of them finished speaking, Mo Yufei on the side slowly raised his hand.

Her move made everyone stunned for a moment.

Lu Ke gave him a look: "What's the problem?" ”

Mo Yufei put down his hand, cleared his throat again, and asked seriously: "Since the murderer was in a hurry to dispose of the corpse, why didn't he throw the deceased's head together?" These three corpse pieces can almost be put together into a complete 'person', except for the missing head. ”

Lu Ke froze and began to answer his question: "In homicide cases, headless corpses or severely disfigured corpses are relatively common, and the murderer's purpose is only one, that is, to cover up the identity of the deceased. In this case, the murderer's murder and dismemberment of the body were very calm, which shows that the murderer was thoughtful and had a strong psychological quality. At the same time, it also shows that the murderer concluded that the police could find him through the identity of the deceased. ”

After Lu Ke finished speaking, he was suddenly silent for a while, and then asked Su Simeng: "Isn't there any news from the Technical Investigation Department yet?" ”

Su Simon shook his head, "No." ”

"What about the witnesses and surveillance at the abandoned site?" Lu Ke asked again.

Su Simeng still shook his head: "I have already sent someone to check, but there is no news yet." ”

Lu Ke thought for a while and said seriously: "I can't wait, give me the map of Jing'an City." ”

As soon as Lu Ke's words fell, Su Simeng immediately pushed away the various documents on the table, took out a flat map of Jing'an City, and spread it on the table. Ling Zizhen took out another red and blue pencil and a transparent ruler and put them on the map.

The three of them didn't use too many words to communicate, and they cooperated tacitly to complete all this.

It is said that Ling Zizhen and Su Simeng are Lu Ke's right-hand men, so it seems that the three of them can really reach the point where they can understand without communication after a long period of cooperation.

Lu Ke stood up and searched the map with red and blue pencils, and he drew a circle on the eastern suburban road where the murderer first threw his body, followed by Shoushan Fitness Park, and finally the abandoned construction site in the northern suburbs.

Then, he connected the three dumping sites in a straight line, forming an irregular triangle.

There were people around the table, and Mo Yufei stood at the outermost part of the crowd, standing on tiptoe, and could only see Lu Ke scribbling around the map with red and blue pencils very intently.

Mo Yufei was afraid of disturbing Lu Ke's thoughts, so she lowered her voice and asked Su Simeng beside her weakly: "What is he painting?" ”

"Psychological safety zone." Su Simon replied.

"Oh." Mo Yufei nodded as if she didn't understand, she knew a little bit when she was flipping through the psychology books.

Su Simeng looked at Mo Yufei's appearance and explained in detail: "Psychological safety refers to a sense of security in the face of the environment in which people live, and it is a psychological mechanism that pursues stability and coping self-protection without threat. A psychological safety zone is an area that usually radiates to the surrounding areas of people's frequent activities, such as home addresses, workplaces, frequented restaurants, entertainment venues, etc. If you are walking, the radius is one kilometer, if you are cycling, it will be about three kilometers, and if you drive, it will be five kilometers, or even further. ”

"In other words, the psychological safety zone refers to the place that people are more familiar with, near the places they frequent, because they are more familiar with the surrounding environment, so they have a sense of security?" Mo Yufei continued to ask.

Su Simeng pondered for a moment and nodded: "It can be understood so. ”

After a while, Jiang Xiran walked into the office of the criminal police team with the autopsy report.

"Did the autopsy find any clues?" Lu Ke still lowered his head, didn't even look at Jiang Xiran, and immediately asked.

Lu Ke's move made Mo Yufei stunned instantly, could it be that the people in the Jing'an City Public Security Bureau have the ability to listen to footsteps and recognize people?

Jiang Xiran sat on the chair, spread out the autopsy report, and said seriously: "The deceased's nails are not long, and he has just had a manicure. She came to Jing'an City alone from Ningzhou City, must have been to see some important person. Her fingers are slender, her skin is smooth, and she is very well maintained, indicating that she does not engage in manual labor, and her life and work are relatively leisurely. Such a person is very conscious of her appearance, but I found a lot of dirt in her nails. ”

Without waiting for anyone else to ask, she gave her own answer: "Before she was killed, she was most likely detained with restrictions on her personal freedom, and the detention place was not clean." ”

"That's right, she came to Jing'an City two days in advance, but she was only killed on ......the third day," Lu Ke echoed casually, he was obviously a little absent-minded, still studying the map in his hand.

Jiang Xiran didn't care about Lu Ke's reaction, and continued: "In the past two days, the deceased should have been imprisoned at home by the murderer, restricting her personal freedom, and giving her cornmeal, cabbage and tofu soup. Therefore, the murder scene and the dismemberment scene should be at the murderer's house, judging from this......"

Before Jiang Xiran's words were finished, Lu Ke took over and continued: "Judging from this, the murderer should live in an independent house. After two days of captivity, the deceased will definitely find a way to call for help, even if the murderer covers his mouth, there will definitely be a sound of killing and dismembering the body, and there will be a smell of blood and corpses in the future, and the neighbors will definitely notice something strange. ”

After Lu Ke finished speaking, he clicked the map with the red and blue pencil in his hand: "This is the old city, there are many single-family bungalows, and the murderer is likely to live here." ”

"Team Lu, this old town is very big, how can we find it? Looking for it by electric tricycle? Ling Zizhen leaned out and looked at the map seriously.

Lu Ke raised his head and ordered seriously: "Also, investigate Gao Junliang, a transport worker in the logistics center, judging from the current situation, he is very consistent with the physical characteristics of the murderer." ”

At this moment, Hu Mingxuan of the Technical Investigation Department walked into the office of the criminal police team quickly and brought a major news to everyone......
