Liu Jinghui has not yet completely read the dossier, but during the grading process, Liu Jinghui subconsciously chose the second corpse to focus on.
This is completely different from Jiang Yuan's idea.
In Jiang Yuan's view, the first and third cases were the ones where the murderer was most likely to make mistakes.
The first crime may be the murderer's first crime. As we all know, the first crime of a serial killer is often imperfect.
By the way, the slogan "Death must be eliminated" was shouted out in 2004, shortly after the Three Corpses Incident. One of the backgrounds was the large number of serial murders that occurred in the country. Of course, it was not called that at this time, but among them
A perception is this:
Because the detection rate of murders is low, many murderers are not punished, which gives them the opportunity to practice and learn to kill. This increases the number and difficulty of serial murders in disguise. Therefore, police forces must be concentrated as soon as possible.
Only by detecting newly discovered murders can we fundamentally curb the spread of serial murders.
For a similar reason, when the police encounter serial murders, they often consider the first case, that is, they first consider the case, and then the first case in the series. Many times, they will even leave the current case alone.
, and first concentrate on checking the first accumulation.
The first piece is very important, and the third piece, as the final production, is even more important to Jiang Yuan, because this piece is obviously carefully arranged, and it is also this piece that has aroused the vigilance of all parties, thus
This eucalyptus has been included in various lists.
The more carefully arranged a piece of software is, the more likely it is that errors will occur.
However, Liu Jinghui's ideas were completely different from Jiang Yuan's.
After an in-depth review, Liu Jinghui approached Jiang Yuan again and said, "I suggest that the second case be the main target of attack."
"Tell me something." Jiang Yuan asked Liu Jinghui to come over to make suggestions.
Liu Jinghui sat down, faced Jiang Yuan face to face, and said: "In my opinion, the second case is actually the most difficult to operate and the most likely to cause problems."
Jiang Yuan said "Hey": "Isn't it the third case? The murderer also used medicine and secretly brought a living person over at night."
"There are still many ways to obtain ether, especially 20 years ago." Liu Jinghui paused and said: "In fact, corpses are more difficult to handle than living people. Even if ordinary people cannot understand the weight of a 100-pound corpse,
I've already kidnapped someone, how could I not understand?"
Liu Jinghui continued: "Furthermore, after the first experience, the murderer could obviously subdue a thin woman and bring her to the railway. Why did he kill her first and then take her there?"
"Third, the problem of the first scene. When someone is killed, there is a first scene. It is still difficult to disguise the first scene. Even if the police never discover the first scene, the murderer should not be able to guess it.
Can the police find it? So, we still need to clean up what should be done at the first scene. In order to hide ourselves and make it easier to clean up at the first scene, do we need a room? Doesn’t this require several hours of work?
Do you own the house or rent it? How to explain it?"
When Jiang Yuan heard this, he nodded slowly. Liu Jinghui's reason was very good. Cleaning up the site was no joke. It was more tiring than cleaning up land after renovation. He could finish it in a few hours because of his own pressure.
It may take longer to replace internal drive with boring work.
Of course, the murderer could also use cleaner methods to kill, such as strangulation. However, the murderer obviously did not use this method. Perhaps he was afraid that contact would leave traces? Or for other reasons. In short, the murderer used assassination.
The way.
Going back to the analysis, no matter which method the murderer initially chooses, he should consider that there will be situations similar to assassination. In other words, time must be arranged and physical strength must be conserved.
Although the above requirements are relatively harsh, as a serial killer who has escaped sanctions for 20 years, his 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 are not a lot of soil, leaves and the like on the body. Killing people in the wild and then transporting them...
Come in, take off your pants and fart, then just throw it outside."
Jiang Yuandao: "It makes sense. Maybe the murderer is a more ritualistic person?"
"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 terms are easy to explain. In the dead of night, it made the two
The first victim can just come over by himself. How was the second corpse brought in?"
Jiang Yuan then fell into thinking. After a while, he said: "There don't seem to be many traces of vehicles at the scene. All they found were the company's cars, and there were no traces."
Jiang Yuan also has the skills to identify vehicle traces, but he can't find any clues even if he looks at the photos.
Liu Jinghui snorted, and then said in a long tone: "Do you think the body was transported by railway?"
[A novel app that has been running stably for many years, comparable to the old book-chasing tool, a source-changing app used by old bookworms, huanyuanapp.org]
"Huh?" Jiang Yuan was stunned. Indeed, if the body was brought by train, it would be easier to carry it. However, the management of trains is much stricter than that of ordinary vehicles.
Huang Qiangmin said from the side: "I read in the report that the railway has also checked this aspect several times."
"It's hard to say, I can only make a guess." Liu Jinghui just read the file and naturally couldn't give any definite answer.
"In that case, we should put the main investigation direction on No. 2?" Jiang Yuan hesitated slightly.
Liu Jinghui nodded again.
Jiang Yuan sighed: "Okay, then change the main direction of attack."
In the past few days, he has killed several people on Body No. 3. The most important thing is that many policemen have done a lot of work based on his judgment.
Now that the police force is being withdrawn and re-invested in corpse No. 2, it will inevitably be regarded as hesitant and a waste of police force. After all, no one is willing to do useless work and do not want what they have done to be easily dismissed.
However, based on his trust in Liu Jinghui and his persuasive judgment, Jiang Yuan easily changed his direction.
Rigongyi's pawn didn't just keep his head down and rush forward.
Now that we have crossed the river, we still need to move our soldiers where they should.
It is easier to change now than to go back to No. 3 if he completely loses the clue.
Jiang Yuan changed it when he said it would be changed, and retook the file of victim No. 2 to read it. Fortunately, the last time the case was restarted, the special team brought over all the evidence from each family, otherwise, now we would look at the file of victim No. 2.
You have to go to other cities.
Soon, the only sound in the room was the rustling of files.
Similar to No. 1 and No. 3, the interpersonal network of Victim No. 2 is not complicated. The three of them are in different cities and have almost no intersection.
This is also one of the reasons why this case is judged to be a serial murder. If the three people are connected and have an interest in the murderer, and then the murder occurs, then it is considered a normal murder with multiple bodies.
.
However, since there is no relationship between the three people, it will be very difficult to crack the case. Random killings have always been a difficult problem in murder cases.
"Tell me, why did the murderer stop after killing three people?" Liu Jinghui looked at the file and asked questions as if talking to himself.
The lights in the office were a little dim. Huang Qiangmin stood up and turned on the lights and said, "Accident? Transferred? Or jailed?"
"This man is a master. He just killed three people and then stopped. It seems unreasonable." Liu Jinghui has always raised problems without solving them. After thinking about it for a while, he simply asked Jiang Yuan and said, "If the victim No. 2 can be found,
The first scene would be great.”
Jiang Yuan reviewed his skills and said: "Then it's forensic botany. Extract pollen from the deceased's clothes to see if we can simulate her travel route on the day of the victim. It may be a bit difficult."
Liu Jinghui has no hope for this. Where can he find the plant distribution map from 20 years ago? He can only shake his head and think hard.
