Seeing this record, my heart was shocked, and in the dark, I estimated that seven or eight times out of ten, this morning exercise aunt accidentally saw this person, is the murderer!

The physical characteristics are also very in line with my psychological portrait, father and son, with tools to throw corpses, life is down, once a person in the system, there is a certain nostalgia.

I subconsciously quickly flipped back to look at the transcript, but unfortunately, there was no transcript of this aunt in the back.

I hurriedly asked Xia Xixi: "Hey, this aunt is very likely to be an eyewitness, why don't you continue to ask later?" What about the latter information? ”

Xia Xixi rolled her eyes: "Auntie said that she wanted to exercise in the morning, and said that she only cared about looking at the 28 beams of bicycles, and didn't care about the appearance of the cyclist, Xiao Zhang and Xiao Wang have asked, comprehensive analysis, the useful value is not much." ”

"Do you remember the contact information?" I asked.

Xia Xixi nodded: "I remember." ”

"Hoo ......"

I let out a long sigh and looked through the transcript again, but as for the others, I didn't ask for any valuable information.

But at least for now, we know that the killer had an old bicycle.

At the end of the busy work in the morning, in addition to this information, there were two other people who were exercising in the morning, saying that they saw two men three days ago, a middle-aged man and a half-old child, riding a bicycle passing by here, and when passing the section of Hongxing Road, the witnesses said that they did not see a black cloth bag hanging on the handlebar.

This is also very consistent with the place where the body was dumped, the murderer rode from Fengming Road to Hongxing Road, passing by the most sparsely populated place in the moat halfway, staying for about ten minutes, and leaving from Hongxing Road.

Red S Group Office.

Everyone was very nervous, Professor Wu and Wang Jianfei were smoking, frowning, desperately looking for the next direction to detect.

After a morning of elimination work, Tang Yu and Xia Xixi eliminated 17 of the 127 people, and there were still 110 people left.

However, the remaining one hundred and ten people don't dare to continue to exclude it drastically, because everyone has the possibility of killing, and in order to avoid missing the real murderer, they can only try to narrow the scope while expanding the scope a little.

Wang Jianfei said: "What now?" You can't really check these 110 people one by one, right? The difficulty of the work is also too great, even if the city bureau does not require us to solve the case within a time limit, these more than 100 people, one by one, will be investigated, not to mention, it will take at least a month! ”

Tang Yu shook his head: "It is impossible to solve the case within a time limit, the head is discovered by the citizens, we must solve the case as soon as possible, in order to eliminate the impact and control public opinion as soon as possible, I estimate that before noon today, the order to solve the case within a time limit should come down." ”

Wang Jianfei hurriedly pressed half of the desire into the ashtray: "It's been 24 hours of busyness, and we haven't even determined the identity of the victim!" ”

Tang Yu raised his head and asked Xiao Meng: "How is the work of finding the victim's other limb parts?" ”

Xiao Meng shook his head and didn't speak, but the meaning was already obvious, that is, there was no progress.

In fact, it is also understandable, just imagine, a huge city with a population of 14 million, mountains and rivers, moats, high-rise buildings, and busy traffic, trying to find a person's limbs, body, and corpse parts in an extreme period of time is almost difficult to find a needle in a haystack.

It's not easy to find a living person, let alone find a dead person who can dig a pit and throw corpses in the river at will?

Tang Yu instructed: "Although it is difficult, the work of finding the victim's whole body still cannot be stopped. If two kilometers can't work, it's five kilometers, and if five kilometers doesn't work, it's ten kilometers! Be sure to find it! I'll report to the city bureau shortly and apply for additional manpower to assist you! ”

"Yes!" Xiao Meng nodded!

"You don't have to report to me! All the people in the whole world can be deployed by you! Feel free to use it, no need to ask me again! ”

At this time, the leaders of the city bureau didn't know when they had appeared at the door of the office, and they were in a very bad mood and rushed over!

Tang Yu hurriedly stood up: "Thank you, leader!" ”

The director didn't continue the topic, and came up to directly blame Tang Yu: "After you received the report, why didn't you find a reason to control those two drunks?" ”

Tang Yu hesitated for a moment, and then said hesitantly: "Drunk...... Drunkards, not sinners, what reason do we have to control them? ”

"If you let them out, it's just two mouths and talking nonsense!! This morning, this matter has been in the news! Originally, I planned to give you half a month's vacation, but even if you can't rest during the holiday now, there is no need to solve the case within a time limit! But in this situation, you say, what can I do except solve the case within a time limit? Before I came to you, my superiors had already stopped calling me! This time the deadline is shorter! Only 48 hours! ”

"48 hours?" Wang Jianfei's eyes widened: "It has been almost twenty-four hours since we received the report, and there has been no progress, this time the murderer has a strong experience in counter-reconnaissance, we have no clues at all, the director ......"

"I'm not here to hear from you how complicated this case is and how difficult it is to solve it!"

The leader waved his hand: "The murderer has experience in counter-reconnaissance, which of you doesn't have strong experience in investigation?" This in itself is a contest between good and evil, and the murderer racked his brains to destroy the corpse and escape after killing someone! When you receive a report, you should do your best to lay a net to arrest the murderer! It's a vocation! I don't want to hear any more complaints! ”

"Yes!"

Everyone stood up in unison, nodded, and the sound of killing shook the sky!

The director sighed: "If you need any technical and manpower support, you don't need to report to me, just call my office directly!" Comrades! This case is not trivial! Murder and dismemberment, bloody to the extreme! This is simply a challenge to our public security organs! This is a war letter against us! In forty-eight hours, I hope to see you catch the real culprit! Give the people justice! Give an account to the deceased! ”

"Yes!"

"Get moving!" The director yelled!

"Yes!"

Xia Xixi and Tang Yu continued to quickly conduct the second in-depth elimination and screening of the one hundred and ten suspects!

Wang Jianfei took Xiao Meng to expand the search scope and determine the identity of the victim as early as possible.

At the same time, Xiao Zhang and Xiao Wang, who ordered the serious crime team, took turns on duty to go to the 110 police center to wait for the call.

The originally smoky office of the Red S team, after the director came to lecture, quickly quieted down, only me and Professor Wu were left, I sat down to smoke, Professor Wu knocked on the table at me: "Give me one too." ”

I smiled and asked Professor Wu, "Can you find me a detailed map of Dongyang City?" ”

Professor Wu's eyes lit up, carefully lit the cigarette, and looked at me: "What do you think?" ”

I thought about it for a moment and said, "I had a bold guess, but I'm not sure if it's correct, so I didn't say it just now." ”

Professor Wu was really satisfied, and quickly took out a map of Dongyang City, spread it out, put it on the table, and beckoned me over: "Tell me, what do you think?" ”

I took out a marker, walked to the front of the map, and used the black marker pen to determine the center of the moat where the victim's head was located.

"What does that mean?" Professor Wu asked me.

I said: "When I was studying at the police academy, my teacher once recommended me to read a book called "The Origin of Crime", which mainly talks about the three psychology of criminals, namely before committing the crime, the process of committing the crime, and after the crime. ”

"Psychological safety zone?"

"Yes, it's a psychological safety zone."

Professor Wu hesitated, squinted his eyes and put the cigarette in his mouth, looked at the map, and said with interest: "I have heard of this proposition before, but in previous cases, no one has used the psychological safety zone formula to solve the case, after all, this is a very abstract and idealistic concept......

"Isn't what Red S wants is imagination?" I said, "Let's let them go ahead according to normal investigative thinking, and I'll see if I can find the murderer's psychological safety zone." ”

"You can give it a try!" Professor Wu patted me on the shoulder: "The future is terrifying!" This idea of yours is really interesting! Maybe you can find a clue! ”

"Try it." I didn't say anything more, and quickly marked out a few points.

Centered on the place where the body was dumped.

Take Fengming Road and Hongxing Road as the east-west depth direction.

In accordance with the formula of the psychological safety zone, a circle of 10 kilometers was demarcated.

After marking on the map, map from the center to the surrounding areas according to the arrangement of the roads and the actual situation.

A circle, a few lines.

I draw it one stroke at a time, and strive to make each stroke horizontal and vertical, without the slightest deviation!

Eventually, the mapping area overlaps in two places.

One is "the most dangerous place is the safest place", which we label as Psychological Safety Zone A, located in a community 0.5 kilometers away from the moat where the body was dumped, called Fenghua Community.

Another intersection of the map mapping curves is a neighborhood near a school called "Datong Community" 10 kilometers away from the dumping site.

When I was done, I let out a long breath, and just as a cigarette spontaneously burned between my fingers, I almost didn't jump!

Professor Wu's eyes widened and he nodded in admiration: "It's amazing, it's amazing!" These two places, according to the psychological safety zone of the murderer in psychology, are indeed very realistic...... The murderer may not only think that the most dangerous place is the safest place, deliberately expand the scope of his tracks, in fact, the hiding place is near the corpse dumping point, or he may run a little farther away to throw the corpse, ten kilometers is the psychological safety distance of a normal person, that is to say, these two places, one of them, must be hiding the murderer!! ”

I shook my head and said firmly: "The murderer is in the Datong community far away from the city center, not in the Fenghua community......"
