Chapter 1095: Maggot Envoy
Snap, snap, snap.
The technician picked up the camera, aimed it at the corpse and the scene around the scene, and it was a murder of film, a symphony of shutters.
Miao Ruixiang, who came over with his family from Ningtai County, was muttering while wearing a three-piece suit.
He is considered Jiang Yuan's junior brother, Wu Jun's closed-door disciple. During his time in Ningtai, he also followed Wu Jun to see many corpses of abnormal deaths, but he was not qualified or had the opportunity to independently dissect corpses that were truly murder cases. Only by following Jiang Yuan did he have the opportunity to learn.
I saw Miao Ruixiang gesturing a few times, then putting on his equipment, and stepped forward to serve Jiang Yuan in the mode of serving his master Wu Jun: "Senior brother, what should I do now?"
"You prepare the bottle first. What is used here?" Jiang Yuan was talking about the poison bottle used in forensic entomology.
"Ethanol." Miao Ruixiang began to take out his equipment.
These maggots on the corpse, including their eggs and adults, etc., must be put to death when caught. Because there is no point in bringing live ones, and because the insects continue to grow, it is easy to interfere with the judgment of the time of death.
Therefore, quickly putting insects to death is the first step in forensic entomology. The poison bottles in textbooks are often two-level structures with upper and lower layers, just like a duplex gas chamber for insects to live in. The lower layer is filled with fumigants, and the upper layer is stuffed with insects. They die while being caught, and the stability is relatively high, and the effect is also good, but it is a bit troublesome, and the cost is slightly higher.
Ethanol is a relatively simple solution. Although it is a bit wetter than being killed by poison gas, alcohol evaporates very quickly, and generally it does not affect the operation too much.
Of course, many districts and counties will also use cheaper solutions, such as scalding with boiling water.
Tiny maggots are particularly white and tender, usually little guys who were born only a few days ago, smaller than any veal, so they are cooked when scalded with boiling water, which is also very convenient, and the appearance is kept relatively complete.
Miao Ruixiang picked up the large maggots and threw them into the ethanol bottle.
Catching maggots is mainly to confirm the time of death of the corpse. Common flies will arrive and lay eggs within one hour of human death. The egg stage is usually one to two days, and what hatches is maggots. Maggots usually have three instars, and the appearance of each instar is different. Finally, they pupate and then emerge as adults.
If there is still nutrition on the corpse at this time, this step can be done again.
In a way that is easier to remember, flies in the egg stage are like the Qi Refining stage. As long as they are sprinkled in places with resources, they can quickly break through to become maggots in the Foundation Establishment stage. Maggots already have a certain ability to move, drilling and drilling on the corpse, and will experience three important changes, just like Foundation Establishment to Golden Core, Golden Core to Nascent Soul.
Maggots in the Nascent Soul stage change again, which is the pupal stage. The pupal stage will last for a long time, often more than a week.
However, once the pupal stage breaks through, it is the time of emergence. Like transformation into a god, there is no obstacle in the world, and you can enter the fairyland.
Adults like transformation into gods are naturally not easy to catch, and the pupal stage and egg stage are just there, and there is no need to catch them.
Only the maggots of the three instars of Foundation Establishment, Golden Core, and Nascent Soul are not easy to distinguish at first glance. If you want to look closely, they are still drilling around, and they can't run away, but it affects observation very much.
I had to pick a large batch to put to death, and then look closely.
The main thing is to find their big senior brother.
It doesn't matter when the little maggots behind were born. To confirm the time of death, the most important thing is actually to determine when the first batch of insect eggs were sown. Further, it is which one is the first maggot born.
A relatively simple method is to compare the size.
Among the same batch of maggots, the one with the strongest skill... no, the one with the largest body size can be considered the first maggot born, and then count back to the time when the eggs were laid, and the time of death can be determined.
These all belong to the basic knowledge of forensic medicine. Mastering them requires about LV0.1 level of forensic entomology, and Miao Ruixiang can easily do it.
I saw him picking up the large ones from the clusters of maggot piles and throwing them into the bottle, and then began to go to the lower three roads of the corpse.
This is not to say that he was influenced by Liu Wenkai, but because when flies lay eggs, they like to lay them in warm, humid places with gaps.
As the saying goes, flies don't bite seamless eggs. In forensic entomology, it is that flies specifically look for gaps to lay eggs.
In this way, the maggots on the lower three roads of the corpse will usually be larger and stronger, just like the central area of a continent, and the maggots in other places are more likely to have migrated from the center.
Miao Ruixiang gently pulled out handfuls of maggots from the lower three roads of the corpse and stuffed them into the large ethanol bottle.
With his movements, and the disappearance of the filling of the maggots, some rotten meat also fell down.
The smell of corpse in the air began to become more intense.
Jiang Yuan put on a 3M gas mask.
A corpse in a maggot state is almost the smelliest state, second only to when the giant view is opened. The latter cannot block the spread of odor even with a gas mask, especially when indoors, it is better not to wear it.
Now it is just right, people are in the wild, and the corpse has not reached the smelliest time period. However, Miao Ruixiang did not wear a gas mask because he had to catch maggots, and the resin mask of the gas mask affected the vision of the details a bit, and catching slowly meant squatting by the corpse for a longer time, and it was in a state of being close to the corpse, so it was better not to wear it.
"Almost there." Miao Ruixiang stopped only when the ethanol in the bottle he caught overflowed.
Jiang Yuan took a look, nodded, and said: "You pick out the large ones on the side, and throw away the small ones."
"Oh." Miao Ruixiang obediently ran to a slightly farther place, moved a survey box over and laid it flat, then poured all the maggots in the poison bottle onto the box, and then straightened them one by one with his hands, and then arranged them by size one by one.
Perhaps because there were too many caught and poured too quickly, some maggots were not dead yet, and were still wriggling on the survey box.
Maggots are different from snakes. Snakes move by abdominal muscles and core muscles, and maggots move by stretching.
That is to say, when maggots wriggle, their length changes.
This completely affects the accuracy of the measurement.
Miao Ruixiang had to put the wriggling maggots back into the poison bottle, and first sort the other well-behaved ones.
I saw that on the survey box, on the right were maggots piled into a rampart, and on the left were maggots lined up one by one. After lining up more, Miao Ruixiang's card point gradually became accurate, and he began to eliminate the smaller ones in batches.
At the same time, after Jiang Yuan completed the initial observation, he put on three layers of gloves.
These three layers of gloves, the outermost two layers are latex gloves, similar to the gloves worn by surgeons during surgery. The innermost layer is a PVC glove used to isolate acid, alkali and grease, similar to the gloves used by many restaurants to eat crayfish or big bones.
After putting on the full set of protective equipment and confirming that the photography was completed, Jiang Yuan slowly turned the corpse under the full recording of the camera.
Jiang Yuan's first touch was that it felt greasy. This is because the fat of the corpse liquefied after the corpse rotted.
At this time, the corpse was slippery, and Jiang Yuan had to use force in his hands to grab the corpse. Just because of this, the already soft and rotten meat was crushed again, and the rotten meat and maggots fell down again.
Caw.
Several crows circled in the air with red eyes, wishing they could knock down everyone at the scene.
"It should be a case." Jiang Yuan crushed several pieces of meat from the corpse before pointing to the place where a large group of maggots were concentrated, and said: "Take a few photos here, take them clearly, it should be a wound."
Flies not only like to lay eggs in the gaps of the lower three roads, but also like to lay eggs in the wounds of the corpse.
At this time, the position pointed by Jiang Yuan could no longer see the specific shape of the wound, but after his reminder, a rough shape could still be seen.
Having this shape is enough to confirm the filing of the case.
Having a corrupt corpse does not necessarily mean it is a murder case. There is also a possibility that someone died accidentally here. Of course, judging from the location of this corpse, criminal police who know the way can tell at a glance that this possibility is extremely low.
But in any case, having the confirmation of a forensic doctor is more comfortable.
Jiang Yuan continued to turn over the corpse. The milky white latex gloves quickly turned light yellow, and the surface began to become pitted, which was the liquid of the corpse's decay corroding the latex.
PVC gloves are temporarily not affected by this. When the outermost gloves began to become uncomfortable, Jiang Yuan stood up silently, took off the outermost gloves, changed into a new latex glove, and then continued to turn over the corpse. ===== CHAPTER 1096 =====
