Jiang Yuan walked around the rubber garden for a long time.

The interior of the rubber garden is very comfortable. The rubber trees are tall and shaded and mosquito-repellent. The ground is repeatedly cleaned by workers with chainsaws and other things. On non-rainy days, strolling in the rubber garden is almost the same as strolling in the park.

Especially when the wind blows, the only heat is dispelled, as if you can feel the Dutch's mood back then.

There was a body that appeared in the rubber garden, and the remaining two bodies were hidden in the bushes on the edge of the rubber garden.

If the second corpse has a certain degree of concealment, the first corpse is basically an open state - not only is it an open state when it is discovered, but it can be imagined that it is actually an open state when it is committed.

If we look at the standards of a serial killer, the level of this killer is not high, almost at the lower level. Because its advancement is too weak, although the second body was hidden in the bushes on the edge of the rubber plantation, it was not long before the first murder case, and the people who died were still in the rubber plantation. It can be said that in the tense atmosphere at that time, the deceased had lost contact for only half a day, and everyone began to look for and call the police.

As expected, the police actively intervened, so that the second body was soon discovered.

I have to say that it was not until this stage that the method of hiding corpses was adopted, which was obviously a bit behind, and it was not surprising that it was found very quickly.

As for the third corpse, the location where the corpse was hidden changed, and it seemed even more clever, but the essence did not change - there was one less person in the plantation, who would not panic, who dared not call the police, and which police station dared not come!

As for the target chosen by the murderer and the way to hide the corpse, it can even be said that this person is still a long way from the serial killer.

Serial killers won't adapt to local conditions so much.

Serial killers should be more out of their original intentions, not out of interests - but they can kill people by the employees of the rubber plantation, which makes them seem too utilitarian. Without the free and easy nature of serial killers, they will lose the characteristics that serial killers are difficult to investigate.

However, after Jiang Yuan walked through the crime scene and looked at it in the rubber plantation, he understood the murderer's choice.

The ground of the rubber plantation is hard, with grass roots and tree roots coiled under the ground, so it is difficult to dig a pit - this can be said to be a common dilemma for burying corpses in tropical areas. Although the ground is quite soft, plants grow everywhere. The more you dig down, the more you get the tangled plant roots, the greater the obstacles. It is more tiring to dig a pit that can bury people than to open half an acre of land in the temperate zone.

Correspondingly, although there are frozen soil layers in the cold zone, it is still difficult to dig a pit. However, there are snow and fallen leaves in the wild in the cold zone, and there are few scavengers. Just find a snow nest to throw the corpse down. The effect is better than burying it in tropical pits.

On the other hand, the He family's Jiaoyuan has been established for a long time. The daily cleaning of various plants in the Jiaoyuan looks quite refreshing, but the woods outside the garden are all over the age of a hundred years.

These plants that have lived together for hundreds of years are like neighbors who have lived together for hundreds of years. They are like an old tree that has been packing its roots for a long time, and have a chaotic generation. What you can see is that the branches and leaves are pulling the roots, the trunks are riding on the necks of other trees, and the crowns are poked in the armpits of other trees...

It is actually not easy to hide corpses in such woods. It is better to walk a few steps in and find a suitable place to stuff people in.

In fact, the murderer also worked hard. When the third corpse was found, there were obvious traces of cutting from the chainsaw next to it...

The Malaysian police even followed the clues of the chain saw. However, chain saws can be replaced with chain saws, so there was no further progress except for increasing the suspicion of the personnel in the rubber plantation.

"Catch the insects." Jiang Yuan stood at the crime scene of the third murder case and directed Shin Yaowei and others to work.

"Yes." Shin Yaowei has been doing hard work a lot, and he doesn't say a word, rolling up his sleeves and doing it.

The environment in the tropical region was not like temperate. He only took two steps inside and saw mosquitoes and beetles surrounding him.

Shin Yaowei had a bitter face and said nothing, but just waved the flycatch net in his hand silently.

"Continue." Jiang Yuan waved his hand, like a cold medieval knight, sending his soldiers to consume the enemy.

Wei Shi chose mathematics this time, in his heart.

Wei Shixian approached Jiang Yuan silently and whispered: "There seems to be photos of the crime scene. The forensic doctor before seemed to have caught many insects. Do we still need to catch them? Is it not appropriate for them to catch them?"

The forensic doctor who first came to the scene did capture a large number of insects and eggs, especially the forensic doctors in the second and third cases. They are experts from the police and face major cases, and they have a comprehensive collection of evidence.

But Jiang Yuan just shook his head and said, "The insects caught by the forensic doctor before can only be considered routine. For fresh corpses, they do not rely on insects to judge the time of death."

"Are you going to use insects to determine the time of death?"

"Assisted, it is mainly to understand the varieties and forms of local insects." Jiang Yuanluo explained.

There are still differences between insects in tropical areas and temperate insects, and iterates very quickly. To compare fruits, insects in temperate areas are like Spain's manufacturing industry, and insects in tropical areas are like Yiwu's manufacturing industry.

If you want to use days, you can analyze it according to the insect guide in the book, but if you want to analyze it more accurately, then using typical examples is definitely not enough.

For example, when people have children, some will have 32 weeks of birth, some will have 30 weeks of birth, some will have 38 weeks of birth, some will have habitual miscarriage, or will not have a birth after the time period, and will have caesarean section. Are there no insects?

Some insects reproduce in corpses, and they do not have a caesare section when they are born prematurely, and they do not have a caesarean section when they are overtime.

If the same premature family continues to reproduce, the difference in time is difficult to ignore.

On the other hand, the insect guide written in the book is far from the medical guide. However, when humans study humans, when samples are sufficient, the typical cases written in the book are still a "typical" that is often invisible, and even every situation occurs, but the typical cases in the book do not exist.

This can be explained by the fact that the knowledge in the book is not updated and iterated enough, or the changes in people are large, and it is also possible that the author of the book is from 4+4, but no matter what, the reality that the knowledge in the book is out of touch with reality exists.

People and books will become disconnected, and insect books will naturally become disconnected.

Therefore, when it is really useful, the doctors in the hospital will rely on their experience. Forensics either expand the scope or do their own experiments.

After all, people who write books can talk nonsense, but people who do things really need to use knowledge.

Jiang Yuan thought so, and so... ordered his subordinates to do so.

Shin Yaowei and others dug insects for a day and a night.

The reason for a day and night is that there are daytime insects during the day and nighttime insects at night. When those corpses were found, they were basically overnight.

The next day, Jiang Yuan selected several typical and important insects and began to hatch in a busy manner.

At this time, Liu Jinghui also completed the first round of transcript reading. Looking back at Jiang Yuan's appearance of raising insects, he couldn't help but smile: "This is a case from half a year ago. Now you are cultivating these insects, are you a little more than a sword? "

"Insects with high mobility have more commonalities, but insects with higher degree of alienation and greater degree of localization. Think about this. "Jiang Yuan looked up at Liu Jinghui and gave a very logical sentence.

Liu Jinghui's eyes lit up after hearing this: "There's something."

"The common flies on corpses fly around, their reproduction frequency and time are very clear, and we are also familiar with them. On the contrary, some local competitive varieties are rare in Shannan, so we need to consider them."

“Competitive variety?”

"For example, ants, leaf weaver ants, they will transport the fly eggs away, and may attack and eat maggots. The result may be that the egg laying time of the beautiful flies we are familiar with, and the frequency of perversion may change. There are also hornets, various beetles, mantis, and dragonflies. They will prey on corpse-eating flies, especially flies in the maggot stage, with poor defense capabilities. Here we need to distinguish between first-time arrivals and subsequent invaders..."

Jiang Yuan introduced things while doing things.

Liu Jinghui frowned and said with a little concern: "You haven't done this complicated before. By the way, when you go to a strange area, aren't the technology suitable?"

"I want to make the time more detailed. In this way, if you make a timeline based on the transcript, won't it be easy to find the murderer?" Jiang Yuan gave a solution that directly pointed to the target.
