Chapter 538: Changing Roads

Liu Jinghui hadn't finished reading the case files thoroughly, but in the process of reading, Liu Jinghui subconsciously chose the second body as the key focus.

This is completely different from Jiang Yuan's idea.

In Jiang Yuan's view, the first case and the third case should be where the murderer is most likely to make mistakes.

The first case might be the murderer's first crime. As everyone knows, the first crime of a serial killer is often imperfect.

By the way, the slogan of "must solve homicide cases" was shouted in 2004, shortly after the triple homicide case. One of its backgrounds was the large number of serial homicides occurring in China. Of course, it wasn't called that at the time, but one of the perceptions was this:

Because the clearance rate of homicide cases was low, many murderers went unpunished, which in turn gave them the opportunity to practice and learn to kill, which indirectly increased the number and difficulty of serial homicide cases. Therefore, only by concentrating police force to solve newly occurred homicide cases in the first time can we fundamentally curb the spread of serial homicide cases.

It is for similar reasons that when the police encounter serial homicide cases, they often consider tracing back to the initial case, that is, considering merging cases first, and then considering the first case in the series. Many times, they even put aside the current case and concentrate their strength to investigate the first accumulated case.

The first case is very important, and the third case, as the closing work, feels more important in Jiang Yuan's feeling, because this case was obviously carefully arranged, and it was this case that aroused the vigilance of all parties, thereby including this case in various lists.

And the more carefully arranged the case is, theoretically, the more likely it is to have loopholes.

However, Liu Jinghui's idea is completely different from Jiang Yuan's.

After in-depth reading, Liu Jinghui found Jiang Yuan again and said, "I suggest taking the second case as the main attack object."

"You tell me." Jiang Yuan invited Liu Jinghui over to make suggestions.

Liu Jinghui sat down, face to face with Jiang Yuan, and said, "In my opinion, the operational difficulty of the second case is actually the most difficult, and it is also the most likely to have problems."

Jiang Yuan said "Eh": "Isn't it the third one? The murderer even used medicine and had to quietly bring a living person over at night."

"There are still many channels to obtain ether, especially 20 years ago." Liu Jinghui paused and added, "Actually, compared to living people, bodies are harder to handle. Even if ordinary people can't understand the weight of a 100-catty body, they have already tied people up, so how could they not understand."

Liu Jinghui continued: "Furthermore, after having the experience of the first time, the murderer could clearly subdue a thin woman and bring her to the railway, so why kill her first and then bring her over?"

"Third, the problem of the first scene. Killing someone means there is a first scene. Camouflaging the first scene is still quite difficult. Even if the police never found the first scene, the criminal should not be able to guess whether the police can find it, so the first scene should still be cleaned up, right? And in order to hide himself, and also to make the first scene easy to clean up, does he need a room? Isn't this a workload of several hours? Is the house his own or rented? How to explain?"

Jiang Yuan nodded slowly upon hearing this. Liu Jinghui's reasons were very sufficient. Cleaning the scene is not a joke; it is more tiring than the wasteland cleaning after decoration. Being able to finish it in a few hours is the internal drive brought by the murderer's own life urging. If it were boring work, the time might be longer.

Of course, the murderer could also use a cleaner way to kill, such as strangulation, but the murderer obviously didn't adopt this method, perhaps because he was afraid of leaving traces? Or for other reasons. In short, the murderer adopted the method of stabbing.

Analyzing it back, no matter which method the murderer chose initially, he should have considered that situations like stabbing would occur. In other words, time must be arranged, and physical strength must be stored.

The above requirements are indeed relatively harsh, but as a serial killer who escaped sanctions for 20 years, this person's ability should not be low.

Liu Jinghui considered even more than Jiang Yuan thought. He continued: "If the first scene is in the wilderness, it is also a possibility. However, there is not much mud or leaves on the body. Killing in the wilderness and then transporting it in is redundant; it's better to just throw it outside."

Jiang Yuan said: "Makes sense. Is the murderer the type with more sense of ritual?"

"I think it's because of the means of transport. 20 years ago, it wasn't easy to get a car. Bicycles and motorcycles were too easy to expose. The first and third cases are easy to explain; it was late at night, and he just let the two victims walk over themselves. How was the body of the second case transported in?"

Jiang Yuan then fell into thought, and after a while, said: "There don't seem to be many vehicle traces at the scene. The ones found were unit vehicles, and nothing was found."

Jiang Yuan also has the skill of vehicle trace identification, and he couldn't find any clues from the photos.

Liu Jinghui hummed, then elongated his voice, saying, "Do you think the body could have been transported by rail?"

"En?" Jiang Yuan was stunned. Indeed, if the train brought the body over, it would be much easier to move, but railway management is much stricter than ordinary vehicles.

Huang Qiangmin said on the side: "I saw in the report that the railway also checked this several times."

"Hard to say, it's just a guess." Liu Jinghui only read the case files, so naturally, he couldn't give any definite answer.

"If you say so, should we put the main investigation direction on No. 2?" Jiang Yuan hesitated slightly.

Liu Jinghui nodded again.

Jiang Yuan sighed: "Fine, then change the main attack direction."

He had already advanced several pawns for the No. 3 body these past few days, and most importantly, many police officers had done a lot of work based on his judgment.

Now pulling back the police force to reinvest in the No. 2 body would inevitably be considered indecisive and wasting police force. After all, no one wants to do useless work, and no one wants what they have done to be easily denied.

However, based on his trust in Liu Jinghui and his set of persuasive judgments, Jiang Yuan still easily changed direction.

Advancing a pawn every day is not about rushing forward blindly.

Now that he has crossed the river, he still has to move the pawns where they should be moved.

Changing now is easier than waiting until No. 3 completely loses clues and then looking back.

Jiang Yuan changed as soon as he said so, and re-read the case files of the No. 2 victim. Fortunately, when the case was restarted for the last time, the special task force had brought all the evidence from each family, otherwise, it would have to go to other cities to read the No. 2 case files now.

Soon, only the sound of turning case files remained in the room.

Similar to No. 1 and No. 3, the interpersonal network of the No. 2 victim was not complicated. The three people were in different cities and had almost no intersection.

This is also one of the reasons why this case was judged as a serial homicide case. If there was a connection between the three people and there was a conflict of interest with the murderer, then it would still be a normal murder case with one case and multiple bodies.

However, there was no relationship between the three, and it was very difficult to solve the case. Random murder has always been a difficulty in homicide cases.

"You say, why did the murderer stop after killing three people?" Liu Jinghui looked at the case files, and as he looked, he asked himself a question.

The light in the office was a bit dim. Huang Qiangmin got up and turned on the light, saying: "Accident? Transferred? Or went to prison?"

"This person is an expert. It doesn't make sense to stop after killing only three people." Liu Jinghui always raised questions and didn't solve them. After thinking for a while, he simply asked Jiang Yuan: "If we could find the first scene of the No. 2 victim, it would be great."

Jiang Yuan flipped through his skills and said: "Then it's still forensic botany. Extract pollen from the victim's clothing to see if we can simulate her route on the day of the incident. It's estimated to be a bit difficult."

Liu Jinghui had even less hope for this. Where can he find the vegetation distribution map of 20 years ago now? He could only shake his head and ponder. ===== CHAPTER 539 =====
