civil forensic

Chapter 565
Liu Jinghui hadn't read the dossier thoroughly, but during the review process, Liu Jinghui subconsciously chose the second corpse as his focus.

This is completely different from Jiang Yuan's idea.

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

The first case may be the first time the murderer commits a crime. As we all know, the first crime committed by a serial killer is often imperfect.

By the way, the slogan that the murder case must be solved was chanted in 2004, shortly after the Three Corpses case. One of the backgrounds was the large number of serial murders in China.Of course, it is not called that at this time, but one of the cognitions is this:
Because the detection rate of homicides is low, many murderers are not punished, which then gives them the opportunity to practice and learn to kill, which in disguise increases the number and difficulty of serial murders.Therefore, it is necessary to concentrate the police force as soon as possible to solve the newly discovered homicide cases, so as to fundamentally curb the spread of serial homicide cases.

For a similar reason, when encountering a serial murder case, the police often consider going back to the original case, that is, consider the merged case first, and then consider the first case in the series.In many cases, they even ignore the current case and concentrate on investigating the first backlog.

The first case is very important, and the third case is more important in Jiang Yuan's feeling as the finale, because this case has obviously been carefully arranged, and it is also this case that has aroused the vigilance of all parties, thus listing this case. included in various lists.

And the more carefully arranged the case, the more likely there will be mistakes in theory.

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

After in-depth review, Liu Jinghui found Jiang Yuan again and said, "I suggest that the second case be the main target."

"Tell me." Jiang Yuan invited Liu Jinghui to come over to offer advice.

Liu Jinghui sat down, faced Jiang Yuan face to face, and said, "In my opinion, the operation difficulty of the second case is actually the most difficult and the most prone to problems."

Jiang Yuan said "Hey": "Isn't it the third time? The murderer also used medicine and quietly brought a living person here at night."

"There are still many ways to obtain ether, especially 20 years ago." Liu Jinghui paused, and then said: "Compared with living people, corpses are actually more difficult to handle. Even if ordinary people can't understand the weight of a 100-jin corpse, I have already kidnapped someone, how could I not understand."

Liu Jinghui continued: "Furthermore, after the first experience, the murderer can obviously subdue a thin woman and bring her to the railway. Why did he kill her first and then bring her there?"

"Third, there is the problem of the first scene. There is a first scene when someone is killed. It is still difficult to disguise the first scene. Even if the police never find the first scene, as the murderer, the criminal should not be able to guess the police. Is it possible to find it? Therefore, what should be cleaned up at the first scene should be cleaned up. In order to hide myself and also to clean up the first scene, do I need a room? Doesn’t this require several hours of work? The house Do you own it or rent it? How do you explain it?"

Hearing this, Jiang Yuan nodded slowly. Liu Jinghui had a very good reason.Cleaning up the site is no joke, it is more tiring than cleaning wasteland after renovation.It can be done in a few hours, which is the internal driving force brought about by the urging of my own life. It may take longer to replace it with boring work.

Of course, the murderer can also use a cleaner method to kill, such as strangulation, but the murderer obviously did not use this method, perhaps because he was afraid of leaving traces of contact?Or for other reasons, all in all, the murderer used the method of assassination.

Looking back at the analysis, no matter which method the murderer chooses initially, he should consider that there will be situations similar to assassination.In other words, time must be arranged and physical strength must be stored.

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

Liu Jinghui thought more than Jiang Yuan thought, and he continued: "If the first scene is in the wilderness, it is also a possibility. However, there is not a lot of dirt and leaves on the body. Kill people in the wild and then transport them." Come in, take off your pants and fart, just throw it outside."

Jiang Yuandao: "It makes sense. Maybe the murderer is more ritualistic?"

"I think it's because of the means of transportation. 20 years ago, it was not easy to get a car. Bicycles and motorcycles were still too easy to expose. The first and third cases are easy to explain. The victim just walks over by himself. How did the body of the second case get in?"

Jiang Yuan then fell into thinking, and after a while, he said: "It seems that there are not many traces of vehicles at the scene, and all the cars found are the cars of the unit, and none were found."

Jiang Yuan still has the skill of identifying vehicle traces, and he can't find any clues in the photos.

Liu Jinghui snorted, then extended his voice, and said, "Do you think the corpse was transported by railway?"

"En?" Jiang Yuan was taken aback. Indeed, if the train brought the corpse, it would save effort to carry it. However, the management of trains is much stricter than that of ordinary vehicles.

Huang Qiangmin said aside: "I read in the report that the railway has checked this aspect several times."

"It's hard to say, I'm just guessing." Liu Jinghui just read the file, so naturally he couldn't give any definite answer.

"In this way, we should put the main investigation direction on No. 2?" Jiang Yuan hesitated a little.

Liu Jinghui nodded again.

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

In the past few days, he only had the No. [-] corpse, and he has killed several pawns. The most important thing is that many policemen have done a lot of work based on his judgment.

Withdrawing the police force and reinvesting it in the No. [-] corpse now, it will inevitably be considered hesitant and a waste of police force.After all, no one wants to do useless work, and they don't want to be easily denied what they have done.

However, based on his trust in Liu Jinghui and his persuasive judgment, Jiang Yuan easily changed his direction.

Rigong didn't rush forward with his head depressed.

Now that the river is crossed, the place where the pawn should be moved still needs to be moved.

It would be easier to change it now than to completely lose clues on the [-]rd and go back.

Jiang Yuan said that if he changed it, he would change it, and he took the file of the second victim again and looked at it.Fortunately, when the case was restarted for the last time, the task force brought in all the evidence from each family, otherwise, they would have to go to other cities to read the No. [-] dossier now.

Soon, the only sound left in the room was the rustling of scrolling through files.

Similar to No. [-] and No. [-], the interpersonal network of No. [-] victim is not complicated. The three are in different cities, and there is almost no intersection.

This is also one of the reasons why this case is judged as a serial murder case. If the three people have a connection, have a stake in the murderer, and then a murder occurs, it is considered a normal murder case with multiple corpses.

However, there is no relationship between the three, so it is very difficult to solve the case. Random killing has always been the difficulty of homicide.

"Tell me, why did the murderer stop after killing three people?" Liu Jinghui looked at the file, looked at it, and asked a question to himself.

The lights in the office were a little dim, Huang Qiangmin got up and turned on the light, and said, "Accident? Transfer? Or jail?"

"This man is a master, and it feels unreasonable to just kill three people and stop." Liu Jinghui always asks questions and doesn't solve them. The first scene is fine.”

Jiang Yuan checked his skills and said, "That's still forensic botany. It's probably a bit difficult to extract pollen from the deceased's clothes and see if she can simulate her travel route on the day she was killed."

Liu Jinghui is even more hopeless about this. Now where to find the distribution map of plants from 20 years ago, he can only shake his head and think hard.
