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, certain plants will quickly take root on 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 covered with weeds, and there are deep marks made by ruts on both sides of the grass. Basically, only off-road vehicles and tractors can travel easily.
A cluster of graves is located at the end of the road.
"I go to the grave when I 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 municipal bureau's forensic doctor been notified?" Jiang Yuan is talking about Wang Lan and others from the Qinghe Municipal Bureau. According to the rules, if there is a fatality in the county, the municipal bureau can be asked to come for support. There are two in Ningtai County
Forensic medicine is considered a powerful county, so it was not necessary to ask for support originally, but Jiang Yuan felt that it was still necessary to reconcile with his colleagues in the city 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."
"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 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 helplessly glanced 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 is 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 reinforce him 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 directly cut off as evidence, and the small plants were folded into loose packages with absorbent paper 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 Jiang Yuan had not had systematic support and a large number of achievements, a normal county bureau would not have developed 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 economic 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.
Once the excavation is done, these plant evidences will no longer exist, so it is better to take specimens directly.
Wang Chuanxing was so dizzy from doing this 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 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. That’s why 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.
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. It means that Zhang Enfan did not make much money? Or the time was too short and there was no time to repair the road.
of?"
This idea is somewhat interesting, Jiang Yuan nodded unconsciously. If you think along this idea, the time when the grave bag was formed in front of you is very important.
If it was formed during the two or three years when Zhang Enfan opened a casino, then it can be considered to be highly related to Zhang Enfan - you already opened a casino, and you still think that I am a good citizen and the police should treat everyone equally, then it is nonsense.
However, if the grave bag takes too long to form, Zhang Enfan's suspicion will become smaller.
As Jiang Yuan was thinking about this, Wang Lan also arrived with people.
What Wang Lan brought was the Niudong cattle forensic doctor from Qianjin District, Qinghe City. The cattle forensic doctor was not originally used for support. The forensic doctor of the municipal bureau belongs to the municipal bureau, and the forensic doctor of the district bureau belongs to the district bureau. However, Wang Lan considered
Jiang Yuan's reputation has soared recently and he has been unhappy, so he decided that he should be treated with a high standard.
Lest Jiang Yuan feel that he is being treated lightly.
Of course, the benefits of bringing more people are also obvious... During the process of digging holes, more people help catch bugs...
When the grave bag was pried open, these little bugs that had grown up relying on the corpse wanted to escape.
The wild is originally suitable for the growth of insects, and there is a large mammal carcass as a food reserve. The insects here have reproduced for who knows how many generations...
If you don’t know, grab him and ask!
Several young people were holding nets and wearing gloves, surrounding the graves to catch insects. Once they caught them, they stuffed them into highly toxic glass bottles.
In a short time, a few people collected dozens of insects, larvae and eggs.
The full picture of the corpse was gradually revealed.
The dark white bones were soaked in some black corpse water, indicating that the lower layer may have been covered with something like a tarpaulin. In other words, this was not a random burial, but more like a planned burial.
.
The cow forensic doctor squatted down and carefully began to pick up the bones.
Jiang Yuan did not take action immediately. He watched from the side first, his expression becoming serious.
Without too detailed verification, Jiang Yuan could tell that the body in the pit was that of an adult woman.
There are actually very few adult women participating in gambling, especially in such town-level gambling establishments.
A township casino like the one opened by Zhang Enfan has nothing to do with the environment. It would be good if it could guarantee basic living conditions.
If casinos in Macau allow gamblers to maintain their excitement for a long time by filling their halls with pure oxygen, township casinos use oxygen deprivation to allow the wildness of gamblers to gain the upper hand and maintain their excitement.
Ordinary women would not even want to play when they see a place like this.
And if you don't participate in gambling, various loan disputes related to money and various behavioral conflicts related to temper will not easily occur.
The cow forensic doctor also saw it, digging and digging in the shallow grave, picking up the bones, fighting and fighting...
After confirming that the body was female, Forensic Doctor Niu couldn't help but look at Jiang Yuan and said: "The gang is responsible for the crime. You are the only one who can find it with such difficulty."
