Chapter 583 Small Grave
Identifying secret graves through forensic botany is a relatively simple application of forensic botany. Calculated, it is about a level 5.
Because it does not need to identify specific plants, it only needs to know that when the soil is turned, some plants will quickly take root in the fresh surface, and new seeds will germinate until the balance is re-established, which often takes decades. time.
On the one hand, the vegetation in the excavated area is in a different growth stage compared with the surrounding environment; on the other hand, the composition and distribution of the newly grown plants are different from the original plant community.
In addition, buried corpses may also chemically change the soil, promoting or inhibiting the growth of plants, or promoting the growth of certain plants and inhibiting the growth of certain plants.
Some people often like to talk about the acid-base balance of the human body. This thing is really useless when a person is alive, but if this person becomes a corpse and is buried not too deep on the surface, then his acid-base balance will be useless. It's really useful.
Of course, as an ordinary 5-year-old botanist, he may need to conduct observations in a specific area and require careful judgment to be able to identify whether there is a secret tomb.
When it comes to a LV3 forensic botanist like Jiang Yuan, the judgment is much easier.
Jiang Yuan arrived at the Zhang family's ancestral grave as quickly as possible.
The road is not easy to walk, it is a pure dirt road. The middle of the road is already overgrown with weeds. There are deep ruts on both sides of the grass. Basically, only off-road vehicles and tractors can travel easily.
A cluster of graves sits at the end of the road.
"You go to the grave when you go to work."
Mu Zhiyang waved to Wu Junhao and others in the distance.
Wu Junhao ran over quickly and said to Jiang Yuan: "I'm protecting the scene first. You pointed out that I didn't let anyone move."
"Okay. Has the forensic doctor from the Municipal Bureau notified you?" Jiang Yuan was talking about Wang Lan and others from the Qinghe Municipal Bureau. According to the rules, when the county has an emergency, it can ask the city bureau to provide support. There are two forensic doctors in Ningtai County, which is considered a strong county. Originally, there was no need to ask for support, but Jiang Yuan felt that it was still necessary to reconcile with his colleagues in the municipal bureau.
At least his colleagues in the city bureau must know what he is doing - Jiang Yuan made this judgment in a state of emotional intelligence.
Wu Junhao responded and said: "I think it will take two to three hours to arrive."
"Okay. Let's take this time to collect other evidence first." Jiang Yuandao.
"Other evidence." Wu Junhao looked at the Zhang family's ancestral graves, then looked at the unfamiliar forest, and whispered: "You don't want to dig up all the other people's graves, do you?"
Jiang Yuan was stunned: "Why would I do this?"
"Where else can I find evidence?" Wu Junhao asked.
Jiang Yuan glanced helplessly at Wu Junhao's shining forehead and sighed: "Forest."
"How to get evidence in the forest?"
Jiang Yuan was happy: "Come on, come on, I'll teach you."
To be honest, this eucalyptus is not even in the investigation stage now, and the body has not been dug out. Who knows if there is a body inside? What if it was a dog.
Just because of Jiang Yuan's reputation, Wu Junhao and others did not ask this question, nor did the forensic doctors from the Qinghe City Bureau who came to provide reinforcements with just a phone call.
Wu Junhao organized his own small commando team and followed Jiang Yuan to start collecting plants.
Jiang Yuan brought a standard herbarium folder with him when he came here. The leaves of large plants were cut off as evidence, and the small plants were folded with absorbent paper into loose packages to preserve them. A large number of weeds were photographed and sampled.
After all these plant evidences are placed in on-site specimen folders, they are finally wrapped in corrugated paper, tightened with elastic bands, and transported out.
When Jiang Yuan was making eucalyptus before, one of the reasons why he did not use forensic botany was that the process was too cumbersome. The preserved evidence would have to be dried and disposed later, and the total cost soared.
If it weren't for Jiang Yuan's systematic support and a large number of achievements, a normal county bureau would not be able to carry out forensic botany technology at all.
If general trace inspection is a public school expense model, forensic botany is a proper private school expense.
If you don't have any financial foundation, don't touch it.
A group of people were busy taking photos and cutting leaves. It took a long time to clear up the area near the suspected grave.
After digging for a while, these plant evidences will no longer exist, so it is better to take specimens directly.
Wang Chuanxing was so dizzy from doing it that he stood up and looked at the Zhang family's graves again. He couldn't help but asked curiously: "Does this mean that this road is just for visiting the graves?"
Wu Junhao said in a dull voice: "It's not surprising. Our family has been raising funds all year round, and the savings are used to build roads."
"How many years will it be guaranteed after repair?"
"There is no problem in seven or eight years, and it can also be done in twelve or thirteen years." Wu Junhao thought about it and said: "In the past, my family built the road by themselves, or people often came up the mountain, and it was not difficult to maintain it. Now there are fewer people coming However, the roads are deteriorating quickly, so we often need to pay for maintenance.”
Jiang Yuan observed the surroundings and said: "In the past, when everyone passed by this kind of road in the village, they would repair it themselves when they had time. It was common for someone with a hoe to pass by and hoe twice. It doesn't work anymore, everyone has to Find a dedicated road maintenance team to repair it regularly.”
Wang Chuanxing glanced at Jiang Yuan to confirm that he was not in Versailles, then shook his head and said: "The road to the Zhang family is not very good. Does it mean that Zhang Enfan didn't make much money? Or the time is too short and there is no time to repair the road. of?"
This idea is somewhat interesting, Jiang Yuan nodded unconsciously. If we follow this line of thought, the time when the grave mound was formed is very important.
If it was formed in the two or three years when Zhang Enfan opened a casino, then it can be considered highly related to Zhang Enfan - you have opened a casino, and you still think that I am a good citizen and the police should treat everyone equally, that's nonsense.
However, if the grave mound is formed too long, Zhang Enfan's suspicion will become smaller.
As Jiang Yuan thought about it, Wang Lan also brought people.
Wang Lan brought Niudong Niu, a forensic doctor from Qianjin District, Qinghe City. Niu was not originally used for support. The forensic doctor of the municipal bureau is the forensic doctor of the municipal bureau, and the forensic doctor of the district bureau is the forensic doctor of the district bureau. However, considering Jiang Yuan's recent surge in fame and the unpleasantness he encountered, Wang Lan decided to treat him with high standards.
Lest Jiang Yuan feel that he was treated poorly.
Of course, the benefits of bringing more people are also obvious... During the process of digging the pit, more people helped catch insects...
When the grave was pried open, these small insects that grew up relying on the corpse wanted to escape.
The wild is suitable for the growth of insects, and there is a large mammal corpse as a reserve food. The insects here have reproduced for who knows how many generations...
If you don't know, catch them and ask!
Several young people took a scoop net, wore gloves, and surrounded the grave to catch insects. When they caught them, they stuffed them into a highly toxic glass bottle.
In a short while, several people collected dozens of insects, larvae and eggs.
The full picture of the corpse was gradually revealed.
The dark white bones, immersed in the black corpse water, indicated that the lower layer might be covered with something like waterproof cloth, that is, this was not a casual burial, but more like a planned burial.
Forensic doctor Niu squatted down and carefully began to pick up the bones.
Jiang Yuan did not start immediately, but watched from the side, his expression had become serious.
Without too much detailed verification, Jiang Yuan could tell that the body in the pit was an adult woman.
And adult women who participate in gambling, especially in such township-level gambling venues, are actually very rare.
For a township casino like the one opened by Zhang Enfan, there is no environment at all, and it is good enough to guarantee basic living conditions.
If Macau casinos fill the hall with pure oxygen to keep gamblers excited for a long time, township casinos use lack of oxygen to let the gamblers' wildness prevail and keep them excited.
Ordinary women would not want to play in such venues.
And if they do not participate in gambling, various loan disputes related to money and various behavioral conflicts related to temper will not easily occur.
Forensic doctor Niu also saw it. He dug and dug in the shallow grave, picked up white bones, and pieced together...
After confirming that the body was a woman, forensic doctor Niu looked at Jiang Yuan and said, "You are the only one who can find such a difficult case for the police station."
