It rained overnight in Licheng, and when it came to Pingdan, it stopped.

The sky was still overcast, with occasional faint clouds drifting through.

Several pools of water on the ground reflected the light, and most of the sewage flowed down the stinking ditch.

Although the rain washes away a lot of dirty things on the road, there are always some that can't be washed away.

For example, the neatly arranged pieces of meat in that place.

Three, three, two, two, two, a head, mixed with some minced meat next to it.

Chen Haifeng's masseter muscles bulged, he stared at the scene in front of him, and only regretted that when he came before, he ate the bowl of noodles with kidneys and vinegared meat, as well as a cut sausage.

That damn subordinate didn't make it clear that it was the case of the butcher on a rainy night!

He decided to eat vegetarian food to clear his intestines in the next few days.

Some of the younger police officers were already throwing up at the green belt with their backs to the street.

The scene is not disgusting, but the sound of vomiting one after another makes people sick to their stomachs.

The forensic doctor squatted there to check, and there were also old police officers taking pictures there.

Chen Haifeng cleared his throat uncomfortably and made a "uh-uh" sound, so as not to really spit it out.

From time to time, he looked to the side of the road, as if waiting for someone.

The investigation at the scene continued, and about five minutes later, a luxury car stopped on the side of the road.

Two people got out of the car one after another, one with a flat head and a healthy wheat complexion, a tall man with a clear plastic bag full of meat buns hooked with his fingers in one hand, steaming, and a meat bun in the other hand and stuffing it into his mouth.

Eat a lot.

The man who got out of the driver's seat had clean and crisp short hair, wearing a gray T-shirt and denim cropped pants.

Zheng Siming greeted Chen Haifeng from afar, and the police officer who intercepted him gave up his position.

"This is the seventh one this year."

Chen Haifeng pointed to the piece of meat on the ground and said straight to the point, but his gaze stayed on Chen Jielong's body.

Because the other party, looking at the meat pieces on the ground, the speed of stuffing the meat buns into his mouth was faster.

Chen Haifeng originally thought that this Chen Jielong had been chewing on the meat buns all the way since he got out of the car, because he hadn't seen these things on the ground, and when the other party saw the meat pieces on this place, he might vomit even more miserable than his subordinates.

But who knows? After this tower-tall man saw the pieces of meat on the ground? Not only did not I get nauseous, but the number of buns in the bag? But it soon bottomed out.

Seem? Still eating?

Maybe he felt that he was not good like this, or maybe he read something from Chen Haifeng's eyes.

I saw Chen Jielong smile innocently? The plastic bag with only two meat buns left stretched out in front of Chen Haifeng: "Eat some?" ”

Chen Haifeng: "... ”

The on-site investigation is almost over, after all, the same case? How many cases have these people dealt with? Everyone is a little familiar with the road.

Only, it's better to look at it once and spit it out once.

Chen Haifeng looked at the report in his hand and said to Zheng Siming: "This rainy night butcher generally chooses to commit crimes on rainy days, and there were six cases in total last year?" But what's wrong this year? It's only June, just half a year, and the number of cases committed has already exceeded the number of last year's whole of last year. ”

"And the strange thing is that he would have only committed crimes on the outskirts of Licheng City, and the farthest place was even near the boundary of Fengze City? It seems to be deliberately moving away from the place of the crime to hide his identity. But today? Is it the closest Rainy Night Butcher has been to the city center in the past few years? I'm worried. ”

Chen Haifeng deliberately left a mouth, wanting to wait for the other party to take the initiative to continue with his next words.

But who knows? Zheng Siming took out his mobile phone? Take a picture of the piece of meat on the ground.

And then? He picked a few and sent them to Fang Zhe, who was far away in Shencheng.

He estimated that at this point, Fang Zhe should be eating breakfast, just disgusting him.

Chen Jielong secretly came over and smiled happily after seeing the content.

Seeing that the photo was successfully sent, Zheng Siming put away his mobile phone without changing his face, and then looked at Chen Haifeng, looking like nothing had happened.

Chen Haifeng: "... ”

The Rainy Night Butcher, as the name suggests, is a runaway who only commits crimes on rainy nights.

In fact, no one knows whether this person is out of control, but Chen Haifeng still defined him as a person out of control, and then handed over the case to the No. 15 Branch of Haixi City.

Although Precinct 15 did not mind having one more pending case in hand, it initially refused to take over the crime because there was no residual magnetic field band peculiar to the out-of-control person at the scene of the crime.

This is a regulation at headquarters.

The Abnormal Crime Handling Bureau only deals with the cases of those who have lost control. Like a serial killer, a perverted murderer, even if the means of committing the crime are extremely cruel, they are not in their charge.

But later, as more and more cases were committed by the butcher on a rainy night, Chen Haifeng gathered all the information and handed it over to the No. 15 branch again.

This time, he also included his own views in the report.

For example, the pieces of meat left at the scene were neatly placed, and they had to come out on a rainy night to commit the murder, based on these two points, it can be judged that the butcher on a rainy night has obsessive-compulsive disorder.

In addition, the butchers on this rainy night are all tailing behind ordinary people, killing the victims with a sneak attack and then dividing the bodies of the victims, Chen Haifeng feels that this does not require any ability, and there will be no residual magnetic field band at the scene, which is also normal.

Yang Haixin felt that what Chen Haifeng said had a certain truth, after all, some people who are out of control will hide their own magnetic field bands, which is difficult to detect.

Therefore, the No. 15 sub-bureau took over this case, but the requirement was that all the cases committed by the butcher on this rainy night in the future must be handled by the two agencies at the same time.

If it is finally found that the suspect is out of control, all will be taken over by the No. 15 sub-bureau, but if not, the No. 15 sub-bureau will immediately withdraw.

That's why, early this morning, people from both sides will show up at the same time.

In fact, Chen Haifeng has been tracking down the butcher on a rainy night for five years.

At first, this man committed his first crime on the border of a neighboring city, and then disappeared for more than a year.

For more than a year, there have been no cases with similar modus operandi.

In the third year, the butcher on a rainy night committed three cases in a remote area of Licheng City, with the same method and the same rainy night.

Last year, there were six; This year is just over halfway through, and it is already the seventh.

In serial homicide cases, the indefinite killing cycle is an important factor that cannot be ignored.

In the killing cycle, there is a very special "cooldown period" and "fantasy enhancement period".

The so-called "cooling-off period" is the period after the deformed needs are released, and the perpetrator does not commit the crime, nor does he continue and sublimate his inner illusions.

The so-called "fantasy intensification period" is a period in which the offender regenerates the need to kill after the cooling-off period, but has not yet externalized it into a concrete act, during this period the offender still does not commit the crime, but will continue to strengthen the fantasy and construct the next killing process in the fantasy.

It is worth noting that the cooling-off period and the fantasy intensification period often show an accelerated state with the occurrence of the case, and this acceleration is actually an escalated state, which makes the offender's criminal behavior almost crazy, and the offender's rational criminal ability is very easy to be submerged in his own constantly strengthened fantasy.

When this happens, the perpetrator will be exposed to more flaws than before.

But it's clear that the Rainy Night Butcher's killing cycle is getting shorter and shorter, but his methods have never changed.

Generally speaking, the murderer who has just started the crime will be very rusty and unskilled in cleaning up the scene, just like a novice.

However, with the increasing number of crimes, the murderer's methods will gradually mature and form his own unique system, which also leads to habit deviations that will expose the personal habits and personal character of many criminals.

These can all be depicted through psychological profiling.

But this rainy night butcher is the opposite, because from the beginning, he is as sophisticated as a mature murderer.

His killing cycle has become shorter, and it seems that there is another reason.

Chen Haifeng sighed, it seems that the case is still far from the day when it is declared cracked.
