Chapter 387 Discussion

 The time of death is two months apart, so many previous investigations can be overturned.

Although it feels a bit outrageous, the reality is that there is always a possibility of failure in forensic time judgment on such a rotting corpse. Not to mention a two-month error, a two-year error is much better than

All.

How can it be so easy to judge the corruption and changes of organisms in different environments? Not to mention the physical and chemical indicators, even if a child over 3 years old is thrown in front of the doctor, he would not be 100% sure how old the child is.

Not to mention the large errors in indicators such as height and weight, even if blood drawing and bone line inspection are allowed, there is still the possibility of overage.

This is still a child whose body has changed a lot. If a 25-year-old leading cadre comes here, even if the file is allowed to be checked, it may not be possible to accurately determine his birth year.

If you kill one now, you may not be able to judge accurately.

Liu Jinghui looked at the file, then looked at Jiang Yuan and said, "If the Luyang City Criminal Police Team finds out about this, they will have to break up with us."

"We don't need their funds or their manpower. It doesn't matter whether they are willing or not." Tang Jia followed him to several places and became very confident.

Liu Jinghui said "yes" and couldn't help but said: "It's really nice to handle cases independently."

He had not handled cases independently before. When he had different opinions, he had to convince the actual case-handling unit to make the other party listen to him before he could operate. Small judgments were okay, but if they were judgments that had a greater impact, sometimes they would

It's more troublesome.

The final decision-making power is always in the hands of the leaders of the case-handling units. There is no way around it.

However, the pressure of non-independent handling of cases is much less. You have no power and no responsibility. If you can help the cities and counties below, it is the best. If you cannot help, it is not their fault.

In fact, Liu Jinghui still does not have to take responsibility. Instead, Jiang Yuan, who is in his twenties, has become the person in charge of the special class.

"Five months before the deceased Li Yuan was discovered, there were records of money transfers through the Internet." Liu Jinghui reconfirmed what he had seen before, sighed, and said, "It is equivalent to saying that the criminal first kidnapped, and then

It turned into murder, with robbery in between."

Jiang Yuan couldn't help but think of the Tan Yong case, which was a very heinous case he had done in his early days. The murderer also kidnapped young women and had a tendency to turn into murder.

Jiang Yuan quickly suppressed his emotions and turned them into logical resources, saying: "From kidnapping to robbery, to killing, keeping the murder weapon, and then abandoning the body, the criminal did a good job in every step. Is it possible to consider it?"

Do you think the criminal is not a first-time offender?"

"It's very possible." Liu Jinghui immediately agreed.

If a crime is viewed as a project, the longer the chain of the project, the greater the possibility of making a mistake, and the more evidence should be left. For example, in a kidnapping, there may be traces of ropes, or handcuffs, or

There are no traces of the plastic lock. It may be that the traces have faded, or it may be that the criminal has the ability to firmly control the victim without restraining him.

Looking at the various escapes, jailbreaks and even counter-killings of kidnapped people in movies and TV dramas, it can be imagined that kidnapping a victim for a long time is actually quite difficult.

Killing people and abandoning corpses is not an easy task, especially when abandoning corpses. Most murderers worry about being discovered and exposed. Therefore, a balance must be struck between the efficiency and completeness of discarding corpses.

All in all, Jiang Yuan does not think that a novice can achieve the current level of perfection in so many chains. "The murderer may have consciously misled us about the time of death." Jiang Yuan put forward another point.

Liu Jinghui looked over.

"It can be seen from the photo that there are many of these scattered at the scene where Li Yuan's body was found." Jiang Yuan took out a photo, projected it directly on the screen, then pointed it with a laser pointer, and said: "These should be flower fertilizers and...

The flower fertilizer in the green belt by the roadside is a kind of flower fertilizer. I think the murderer may have taken the flower fertilizer from the green belt by the roadside and mixed it into the soil where the body was buried. This method can accelerate the decay.

It can also confuse our judgment of the time of death."

Jiang Yuan

The photo released is of a scene at a corner of the national highway.

This is also the burial site where Li Yuan's body was exhumed. In the widest angle photo, you can see an excavator, several vehicles, and multiple engineering personnel parked at the site. The burial location is twenty or thirty meters away from the national highway.

There is a green belt in the middle, which has been dug up at this time, and the place where the body is buried is a gravel open space, which was probably used as a site during the previous construction, but it has been dug up again.

Rubbles, old building materials and tools, clods of earth and corpses, newly grown trees and grass, as well as turned soil and stagnant water, when ordinary people look at them, they can only experience disgust and confusion.

Liu Jinghui looked at the photos on the screen carefully, hesitated slightly, and said: "The scene was not well preserved, so it is difficult to confirm whether these are specialized flower fertilizers, or whether they were dug out of the graves where the corpses were buried."

The scene in the photo is already the scene after the excavator has dug it. Moreover, the excavator has been working for a long time. The green belt beside the road has also been dug, and the land nearby has been leveled. It is completely

, the appearance of the newly excavated construction site, it is difficult to confirm whether there is flower fertilizer where the body was buried, how much, and whether it was intentional.

Jiang Yuan actually knew Liu Jinghui's worries. He himself came to the conclusion after in-depth thinking in this regard, and said: "In fact, there is no need to confirm the matter of flower fertilizer. From the time of death and the degree of decay of the body,

Judging from the generations and types of the maggots nearby, there must be other factors that speed up the decay of the corpse and affect the types of insects. Judging from the state of the scene, it is more reasonable to mix some flower fertilizer when burying the corpse."

Liu Jinghui nodded as if he understood, thought for a while, and said, "You can check whether flower fertilizer was added to the green belt here at that time, when exactly it was added, and what type it was. The road maintenance department should have records.

"

"Good idea." Jiang Yuan nodded.

A criminal police officer immediately raised his hand and took the initiative to look up the information.

Liu Jinghui pondered for a moment and said, "Assuming that flower fertilizer was indeed mixed in, can we confirm whether he mixed it in accidentally or consciously?"

"The amount accidentally mixed in is not large enough." Jiang Yuandao. "Is it possible? Hua Fei said he brought it himself."

"It's possible." Jiang Yuan couldn't rule out this possibility.

Liu Jinghui, on the other hand, answered the question he raised: "Actually, it is unlikely that according to the principle of burying the body far away and burying it close, the murderer chose to bury the body here, and he also had to bring his own fertilizer. The amount cannot be small, and the workload is too much."

Alright."

"Yes." Many people present nodded.

We are all criminal police officers who have done murder cases. After watching the scene a few times, we will have a similar understanding. Murderers usually tend to streamline their plans. Burying a body is not about camping. A car and a shovel are the most basic configuration units.

, that’s it, there are still people who leave cigarette butts at the scene during the burial process and get caught.

If you really bring a lot of things to bury the body, the possibility of leaking information is very high. Moreover, a body is already heavy enough and you need to transport a bag of fertilizer? Rather than doing this, it is better to chop off the head of the body.

It's safer to bury it somewhere else, or...

If a person has buried several corpses, there is a high probability that he will sum up some of his own experiences.

"It shows that he is a somewhat smart guy. At least he knows that putting fertilizers and corpses together can interfere with the forensic identification." Liu Jinghui summed it up and then said: "There should be another car, probably coming along the national highway, but there are also

Maybe he's a local, hmm. If he comes from afar, has the patience to bury the body, and notices the fertilizer in the green belt, this guy's psychological quality will be great."

At this time, everyone began to speak:

"If the car is coming from out of town, it will have to pass through checkpoints along the way. The risk factor will be higher."

"Have you found any similar cases?"

"Not yet."

"The body of the second victim was not found, just an arm. It is said that the stray dog ​​on the roadside dug out the arm, so it is impossible to eat all the other parts of the body."

"Luyang City mobilized a large number of manpower to search for it, but could not find it."

The policemen on Jiang Yuan's backlog case team were having a heated discussion when Jiang Yuan's cell phone rang.

Jiang Yuan picked up the call and heard Huang Qiangmin on the other end of the phone say: "The Luyang Criminal Police Detachment has sent someone here and wants to see you."
