clap clap.
The technician picked up the camera and pointed it at the corpse and the scene around the scene, which was a murder film move, with the shutter clicking wildly.
Miao Ruixiang, who came with his family from Ningtai County, was putting on a three-piece suit while humming and muttering.
He was Jiang Yuan's junior fellow apprentice and Wu Jun's last disciple. During his time in Ningtai, he followed Wu Jun to see many corpses of abnormal deaths. However, he had neither the qualifications nor the opportunity to independently dissect corpses that could be considered murder cases. Only by following Jiang Yuan could he have the opportunity to learn.
Miao Ruixiang gestured a few times, put on his equipment, and then stepped forward to serve Jiang Yuan in the same way he served his master Wu Jun, saying, "Brother, what should I do now?"
"You prepare the bottles first. What are they used here?" Jiang Yuan was talking about the poison bottles used in forensic entomology.
"Ethanol." Miao Ruixiang began to take out his equipment.
All maggots on corpses, including their eggs and adults, must be killed if caught, because there is no point in keeping them alive, and because the maggots continue to grow, which can easily interfere with the judgment of the time of death.
Therefore, killing insects quickly is the first step in forensic entomology. The poison bottles in textbooks are often two-level structures, like a duplex gas chamber for insects to live in. The lower level is filled with fumigants, and the upper level is filled with insects. They are killed while being caught. It is relatively stable and effective, but it is a bit troublesome and the cost is slightly higher.
Ethanol is a relatively simple solution. Although it is a little more lethal than poison gas, alcohol evaporates quickly and generally does not affect the operation much.
Of course, many districts and counties will use cheaper solutions, such as boiling water.
The tiny maggots are exceptionally white and tender. They are usually just a few days old and smaller than any veal calf. Therefore, they can be cooked simply by blanching them in boiling water, which is very convenient and their appearance is kept relatively intact.
Miao Ruixiang picked up the big maggots and threw them into the ethanol bottle.
Catching maggots is mainly to confirm the time of death of the body. Common flies will arrive within an hour of death to lay eggs. The egg stage is usually one to two days, and the maggots will hatch. Maggots usually have three instars, and each instar looks different. Finally, they turn into pupae and then emerge as adults.
If there is still nutrition in the body at this point, this step can be repeated.
To put it in a more memorable way, the flies in the egg stage are like the Qi Refining Stage. As long as they are scattered in places with resources, they can quickly break through to become maggots in the Foundation Establishment Stage. Maggots already have a certain degree of mobility, and they will go through three important changes while drilling on the corpse, just like the Foundation Establishment Stage to the Golden Core Stage, and the Golden Core Stage to the Nascent Soul Stage.
The maggots in the Nascent Soul stage undergo another metamorphosis, which is the pupal stage. The pupal stage lasts for a long time, often more than a week.
However, once the pupal stage is broken through, it is time for the emergence of new creatures, just like a god. There will be no more obstacles in the world and one can enter the fairyland.
The adult insects that are like gods are naturally difficult to catch, and the pupae and egg stages are already there, so there is no need to catch them.
Only the maggots in the third stage of Foundation Establishment, Golden Elixir and Nascent Soul are difficult to distinguish at first glance. If you look closely, you will see that they are still burrowing around like cricket pupae. They cannot escape, but it affects observation.
I had no choice but to pick out the big ones and kill them in batches, then take a closer look.
The main thing is to find their senior brother.
It doesn't matter when the following maggots are born. If you want to confirm the time of death, the most important thing is to determine when the first batch of eggs were laid. To put it more specifically, which maggot was born first in the first batch.
A relatively simple method is to compare sizes.
Among the same batch of maggots, the one with the strongest power... no, the one with the largest body size, can be considered the earliest born maggot. Then, by working backwards from the time when it laid eggs, the time of death can be determined.
These are all basic forensic knowledge. To master them, one needs about the level of forensic entomology LV0.1, which Miao Ruixiang can do easily.
I saw him picking up the big ones from the clusters of maggots and throwing some into the bottle, and then he started to move to the lower part of the corpse.
This is not to say that he was influenced by Liu Wenkai, but because flies like to lay eggs in warm, humid places with cracks.
As the saying goes, flies don't bite eggs in cracks. In forensic entomology, flies specifically look for cracks to lay their eggs.
As a result, the maggots in the three paths under the corpse are usually larger and stronger, just like the central area of a continent. The maggots in other places are more likely to have migrated from the center.
Miao Ruixiang deftly took out handfuls of maggots from the lower body of the corpse and stuffed them into a large bottle of ethanol.
As he moved and the filling of the maggots disappeared, some rotten meat fell down.
The stench of corpses in the air began to become stronger.
Jiang Yuan put on a 3m gas mask.
The maggot-infested corpse is almost the stinkiest state, second only to the giant when it is cut open. The latter is not enough to block the spread of odor even with a gas mask, especially when indoors, it is better not to wear one.
Now is just right, people are in the wild, and the corpse is not at its stinkiest time. However, Miao Ruixiang did not wear a gas mask, because he wanted to catch maggots, and the resin mask of the gas mask somewhat affected his vision of details. If he caught them slowly, he would have to squat beside the corpse for a longer time, and he would be close to the corpse, so it was better not to wear one.
"Almost done." Miao Ruixiang stopped only when the ethanol in the bottle overflowed.
Jiang Yuan took a look, nodded, and said, "Pick out the big ones next to it, and throw away the small ones."
"Oh." Miao Ruixiang obediently ran to a slightly farther place, moved an investigation box over and laid it flat, then poured all the maggots in the poison bottle onto the box, then straightened them one by one with his hands, and then arranged them according to size.
Perhaps because too many were caught and poured out too quickly, some of the maggots were not dead yet and were still wriggling on the inspection box.
Maggots are different from snakes. Snakes move by using their abdominal muscles and core muscles, while maggots move by stretching and retracting.
That is to say, when the maggot wriggles, its length changes.
This completely affects the accuracy of the measurement.
Miao Ruixiang had no choice but to put the squirming maggots back into the poison bottle and sort the other well-behaved ones first.
On the survey box, there were piles of maggots on the right, and maggots lined up on the left. As there were more and more maggots in a row, Miao Ruixiang became more and more accurate in marking the spots, and began to eliminate the smaller ones in batches.
At the same time, Jiang Yuan put on three layers of gloves after completing the initial observation.
The outer two layers of gloves are latex gloves, similar to those worn by surgeons during surgery, while the innermost layer is a PVC glove used to isolate acids, alkalis, and greases, similar to the gloves used in many restaurants to eat crayfish or large bones.
After putting on a full set of protective gear and making sure that the photo shoot was complete, Jiang Yuan slowly turned over the body while the camera was recording the entire process.
The first thing Jiang Yuan felt was that it was greasy. This was because the body fat had liquefied after it had decayed.
The corpse was so slippery that Jiang Yuan had to use force to grab the corpse. However, the already soft and rotten flesh was crushed again, and the rotten flesh and maggots fell out again.
Ga.
A few crows were circling in the air with red eyes, wishing they could knock down everyone present.
"It should be a case." Jiang Yuan tore off several pieces of flesh from the corpse, then pointed to the area below where a large group of maggots were gathered and said, "Take a few photos here, take clearer ones, it should be a wound."
Flies not only like to lay eggs in the crevices of the lower body, but also in the wounds of corpses.
At this time, the specific shape of the wound could no longer be seen at the location Jiang Yuan pointed to, but after his reminder, a rough shape could still be seen.
This shape is enough to confirm the case.
The presence of a decayed corpse does not necessarily mean a murder case, it could also be that someone died here accidentally. Of course, given the location of the body, a knowledgeable detective would know that this possibility is extremely low after just a glance.
But no matter what, it would be more comfortable to have forensic confirmation.
Jiang Yuan continued to look through the corpse. The milky white latex gloves soon turned light yellow and the surface began to become bumpy. It was the decaying liquid from the corpse that corroded the latex.
PVC gloves were temporarily unaffected by this. When Jiang Yuan's outermost gloves began to become uncomfortable, he stood up silently, took off the outermost gloves, put on a new pair of latex gloves, and continued to look through the corpse.
