In the dark dormitory, I sat alone for a long time and thought a lot, but no matter how I analyzed, I just didn't think clearly why Chen Peng killed these people, and what was his motive for killing?

Turn on the desk lamp, find out the professional notes from the university class, and look through the records about the criminal motives that Chen Peng told us about the criminal motives.

According to Chen Peng's explanation at that time, all homicide cases evolved from a small matter, which may be trivial at the beginning, but in the end it turned into a serious homicide. At the time, I didn't know if Chen Peng's idea was right or if it was just his family talk.

However, after coming into contact with these various criminals, I realized that what he said was reasonable. In fact, in our lives, homicides are still much less than other cases, especially vicious homicides, which are even rarer.

Love kills! Vendetta! Intentional homicide! Manslaughter!

The homicide cases I have come across in Beijiang Prison these days seem to have verified Chen Peng's statement back then. But there was a kind of homicide back then, but Chen Peng only let us think about and verify it ourselves, that is, --- perverted serial murder case!

He only said one sentence, this is a homicide case that all students of criminal psychology want to know the answer, but until now there is no perfect answer, because the murderer of each perverted serial murder case, their psychology is different, and everyone's criminal motives are also strange, many of which are found impossible or absurd by normal people, but it is these impossible reasons that have become the real thoughts of those perverted murderers to kill.

******

For Bac Giang, a relatively calm and even somewhat lazy small city, a fight on the side of the street is enough for many people to talk about it for a while.

It is conceivable that a horrific serial murder case of corpse mutilation occurred in this small city, and the impact on all the citizens of Bac Giang City was huge.

It is no longer enough to describe the feelings of the citizens of Beijiang City at this moment, because the murderers of many other homicides have a clear purpose and the person they want to kill, and they will not kill unrelated people.

However, in many cases, the next target of a psychopathic homicidal maniac is difficult to predict, and as long as they do not maintain some special killing habits, it is often difficult for people to know who the next victim will be. Their choice of targets is also very much random.

In the criminal psychology class of Bac Gang University, the discussion of the "11.11 Serial Corpse Crushing Murder Case" has become a necessary topic for all students to communicate with since the moment the crime occurred.

"Catfish! Your father and mother are from our Municipal Public Security Bureau, you must know a lot of inside information about the corpse shredding case, tell us about it......" A small, round-faced boy with a thick pair of bottle-bottom glasses walked with a catfish on the path to the school building.

"I really don't know more about this corpse shredding case than you do, and you also know my relationship with my father. There is very little communication when we are together, let alone this very moment. It is estimated that all his thoughts now should be on solving the case. It is impossible to call me, let alone reveal the details of the mutilation to me. So, it's impossible for you to know some scoops from me. Nian Yu and the man with glasses walked side by side and said to him with a smile.

"Yes! How could your dad be so strict and talk to you! Otherwise, when class is over, we will ask Mr. Chen if he has any analysis of this corpse mutilation case. After thinking for a while, the man with glasses said with an excited and expectant expression.

"Didn't Mr. Chen tell me! Among all the criminals, the psychology and criminal motives of serial perverted murderers are the most difficult to analyze, and it is estimated that Mr. Chen can give you an analysis, but it may not be the truth of the matter. Nian Yu said softly.

"What? Do you have doubts about our professional knowledge of Mr. Chen? Don't you like to listen to Teacher Chen's classes? Why is he so unconfident in him? The man in glasses asked with a smile.

"Mr. Chen's professional knowledge is indeed very powerful, but he himself said that we can't generalize about serial perverted murderers, do you remember what Mr. Chen said?"

"What?"

"If you want to know what a madman thinks, you have to be a madman yourself, otherwise how can you know what's going on in the mind of a madman!" Nian Yu said with a smile.

"If, according to you, I want to know why the psychopathic murderer kills people, I have to kill a few people first? If that's the case, I'll use you as a test first. What do you think? The man with glasses pulled Nian Yu's arm and deliberately showed a fierce and vicious expression.

"Don't take me as a test subject, if you don't kill me, you will be disgusted to death first." Nian Yu smiled and knocked off the hand of his glasses and walked forward quickly.

While Nian Yu, a student of criminal psychology, was still using his imagination to guess the corpse shredding case on campus, the police officers of the special case team of the Beijiang City Public Security Bureau were in the store of the Chengbei District Farmers' Market, collecting evidence on the scene on the scene of the fragmented remains of the entire room of victims.

This is a nearly 200 square meters of street stores, and many such street stores in the surrounding area, facing the street is an iron roller shutter door, after entering the door is two or three meters long wooden counter, the counter board is soaked with old blood stains have seen the original color of the wood, size, different shades of knife marks densely covered the entire board.

Behind the counter are two rows of freezers against the wall, in which all kinds of livestock and poultry meat products are stored in refrigeration, and on the shelves above the freezers, all kinds of ready-to-eat foods have been packaged.

In the storage at the back, several busy forensic doctors are conducting on-site investigations at the moment.

On the simple gas stove, a half-meter-high white steel drum has been cooling for a long time. The outside of the white steel barrel is as clean as new, but a thick layer of grease inside the barrel is condensed on the top layer, covering the soup in the entire barrel underneath.

A middle-aged male forensic doctor endured the churning of his stomach and used a colander to try to remove the thick layer of grease and check what was underneath.

"How much hatred does this have to be to do this?" The middle-aged male forensic doctor had to swallow a mouthful of stomach acid that had just returned, and muttered to himself at the victim's skull in the white steel bucket.

Behind the male forensic doctor, Li Jie is taking a younger female forensic doctor to investigate the traces of some moldy sauce bones on the shelves and take video shots.

This is already the third group of forensic doctors who have entered the scene to investigate, the first two groups of forensic doctors ran out of the store not long after they came in, many people retched directly outside the store, and a female forensic doctor who had just joined the work for a long time directly vomited vomit into the mask that he didn't have time to take off.

Nian Hong stood outside the roller shutter door of the store room, whenever the forensic doctor put the human tissue at the scene into the evidence bag, Nian Hong's brows were deeply locked, looking at those large and small evidence bags, Nian Hong's mood had never been so irritable.

Although eleven human fingers were found at the scene of the hot pot restaurant a few days ago, Nian Hong did not expect that this would be the case at the scene of the crime.

At this moment, Nian Hong looked at the scene in front of him, it did not look like a murder scene, but it looked like a messy kitchen, except that what was cooking in this kitchen was not ordinary livestock and poultry meat, but pieces of human flesh one after another.

"Director, I just asked the surrounding shops, this has not been open for a while, and the last time I saw this place open was at the beginning of the month, probably around November 7 or 8." Zhang Haoming, the head of the Beijiang City Criminal Investigation Detachment, walked to Nian Hong's side and said softly.

"Has the owner of this shop checked?" Nian Hong asked in a deep voice, and after giving Zhang Haoming a look, he walked outside the cordon.

"Checked! The couple disappeared half a month ago, and his family is still looking for them everywhere, if it weren't for the police in the sub-bureau below who felt that the couple's disappearance was suspicious, and saw our internal investigation notice, I'm afraid we wouldn't have found this for a while. Zhang Haoming followed behind Nian Hong and whispered.

"When did you get a report of disappearance?" Walking outside the cordon, Nian Hong lit a cigarette and took a puff, then handed the cigarette case in his hand to Zhang Haoming.

Zhang Haoming took the cigarette case handed over by Nian Hong, put it to his mouth and lit one, and said: "On October 30, the son of the owner of this shop went to report the case. ”

Outside the cordon, the entire farmers' market is close to the shops at the scene of the crime, and the streets of more than 50 meters are all blocked by the police and police cars on duty, and some onlookers can only keep looking at this side from a distance, and some media reporters are mixed with the onlookers, holding a camera with a high-powered lens to take some valuable pictures, but the police on duty in front of them block the lens with their bodies.

"Investigate the couple now and get a full picture of their social relationships, the more detailed the better!" Nian Hong threw away the cigarette butt in his hand, stomped on the cigarette butt with his foot, and said to Zhang Haoming.

"Okay! Someone has been arranged to check, and there will be results soon. ”

Zhang Haoming, as an old criminal investigator who has been with Nian Hong for nearly 20 years, knows Nian Hong's temper very well, not to mention the tacit understanding between the two people.

"How's the missing person search?"

"There has not been much progress, and in the last two months there have only been two reports of missing persons, including the husband and wife of this shop." Zhang Haoming shook his head and replied.

"Then let the following sub-bureaus conduct house-to-house investigations, focusing on migrant workers and people living alone in the city. First of all, it is necessary to find out the identities of these 11 people, see if we can find some common ground from them, and confirm their identities from the corpses of these victims, which is too much work and too long. Now I can only use the stupidest way, MD, it's the first time I've encountered such a crazy guy in so many years. Nian Hong gritted his teeth and cursed.

"Director, the leaders above are very concerned about this case?"

"Can you not pay attention? The nature of this case is so bad, and it is about to end the year, and the panic caused to the people alone is enough for us to drink a pot, if we really can't solve the case before the year, we will all have to pick up the skin and leave. As soon as Nian Hong thought of the guarantees he made to the provincial and municipal party committees, his head suddenly became two big, and there was no way that he, the director of the public security bureau, was not at the forefront at this time.

Three days later, Li Jie walked into her husband Nianhong's office with a forensic report that had just come out.

According to the on-site investigation and various tests in the later stage, a total of 11 victims were found at the four scenes, all human tissues belonged to these 11 victims, and the DNA of the 12th human tissue was not found. The time of death may be more than a month.

After comparing the DNA of the families of the two missing cases, it was determined that two of the deceased were husband and wife from the shop at the scene of the crime. The remaining nine adult female victims were all between the ages of 15 and 25.

In addition, no valuable fingerprints were extracted at the scene of the crime, and all the murder weapons were original knives in the shop, but they were processed on top and no fingerprints were found.

For a while, the "11.11 Serial Corpse Crushing and Murder Case" came to an impasse, but half a month has passed since the first report of the hot pot restaurant, but just when all the police of the special case group were at a loss for the case, a courier letter was sent to the Criminal Investigation Detachment of the Beijiang City Public Security Bureau......
