"What evidence?" Cheng Ziqin now knows so much about this young man about the same size as herself, and it is all unheard of, and her heart is full of surprise and curiosity, but before she proves that what Yang Tashan said is true, she is only surprised and curious. Pen & Fun & Pavilion www.biquge.info

Yang Tashan said: "The growth and development of flies is divided into four stages: eggs, maggots, pupae and flies, I have already said that the maggots of flies and hemp flies turn into pupa, it generally takes four to thirteen days, and the average is about eight days, which means that if we can find a new pupa of flies under the corpse, it can be estimated that the time of death of the deceased is about eight days." ”

Speaking of this, Yang Tashan squatted down and scraped the soil on both sides of the corpse with a probe: "Please see that there are no fly chrysalis under the corpse, so the time of death of the deceased should not exceed eight days." In this way, we limit the time of death to four to eight days. ”

The more Cheng Ziqin listened, the more interesting he became, and asked, "Then there are still four days, which day is it?" ”

"Then we need proof."

"What evidence?" Cheng Ziqin saw the bottle in Yang Tashan's hand at a glance, "Do you rely on these flies and maggots you raised?" ”

"Yes, these two bottles of maggots, one is a sample of maggots, used to measure the length, the average growth of maggots is 0.2 to 0.3 centimeters per day, as long as the length of the maggots is measured at the moment, I can reverse deduce the approximate time of death of the deceased; Another bottle ......"

"Wait! What does 0.3 centimeter ...... and what does it mean? ”

"This ......" Yang Tashan didn't know why he had this concept of length in his mind, and he didn't know how to explain it, so he replied procrastinatingly: "This is a kind of ...... A...... A way to measure maggots, which is very ...... Complicated, it's a hassle to say......"

"Alright, alright!" Cheng Ziqin frowned and waved his hand, "What are you doing again, you can go on, what's wrong with the other bottle?" ”

Yang Tashan smiled and continued: "The other bottle is maggots extracted from different wound positions, the length is somewhat different, it is estimated that the species of flies are different, and after I raise them as flies, I will identify the species of these flies, and then according to their growth laws and the current temperature...... No, if the weather is hot, it can be determined how much time it takes for this fly to grow to such a long length, plus the blank time before they find the corpse and start laying eggs, this time is also regular, so that a more accurate time of death can be determined. ”

"Accurate? How accurate is it? ”

"It's probably accurate enough that the error is less than a day. This is already a difficult conclusion for a corpse that has been dead for many times and has been at a high level. ”

At this moment, I heard Ma Liang, the leader of the second group of fast catchers in the distance, shouting: "Two heads!" A man's head was found here! Come and take a look. ”

Cheng Ziqin looked at Yang Tashan in surprise: "You guessed it accurately, this head is really nearby." ”

The two of them hurried to Ma Liang's place, which was a low-lying pit with half a pool of stagnant water, and the back of the man's head was partially immersed in the water, and his long hair was scattered in the water, and most of his head and face were exposed to the water, and it was crawling with flies and white maggots.

Cheng Ziqin asked Ma Liang: "You haven't touched this head, have you?" ”

"No, when we searched here, we found that there were a lot of flies buzzing, so we suspected that there might be a problem, followed the flies, and found this puddle, and found that there were a lot of flies here, around a round thing, and identified it, and found that this thing seemed to have long hair, so I guessed that it might be a human head, and when I opened the fly, I saw that it was indeed a human head. I don't know if it's the human head of the headless female corpse. ”

"Good!" Cheng Ziqin praised, "You go on and search to see if there are any other finds, such as a lot of blood-soaked dirt or thatch—there should be a lot of flies gathering there, and then see if there are any dresses or something." ”

The crowd quickly agreed, and continued to dragnet search.

When Cheng Ziqin explained the matter, Yang Tashan had already squatted down next to the head and observed carefully.

In the long black hair, nostrils and mouth of this head, there are dense maggots crawling in and out, and some fly maggots burrow under the skin of the head and face, forming subcutaneous air sacs one by one, constantly agitating, making the already high [***] human head look as if it is smiling. The eyes of the skull have been eaten by maggots, and the two eye holes are full of white maggots, rolling in the eye sockets, and at first glance I thought that the human head was smiling and rolling its eyes, which was creepy.

Cheng Ziqin also squatted down, pinched his nose and looked at it for a while, seeing that Yang Tashan was watching it with relish, he kept turning the head over and looking at it upside down, and he was a little surprised, and he couldn't understand what he was staring at this dead man's head all the time, so he asked, "Hey!" What are you looking at? ”

"Look at whether this head is male or female, whether it is a whole with the headless corpse, whether this person committed suicide or homicide or accident."

"Oh? This maggot-ridden head can solve so many problems? ”

Yang Tashan raised his head and looked at her: "Dead people will tell you a lot of things, if you listen patiently. ”

"You...... Don't be scary, okay! Cheng Ziqin glanced at the eerie smile on the human head.

"What I said is true." Yang Tread Mountain Road.

"And what did the dead man's head tell you?"

"First of all, the location of the dislocation and fracture of the cervical vertebrae of this human head and neck is exactly on the fifth cervical vertebrae, which coincides with the location of the dislocation and fracture of the cervical vertebra of the corpse.

Cheng Ziqin asked, "How can I confirm it further?" ”

"It is necessary to determine whether the time of death of the head and the corpse coincide, and if there is a significant inconsistency, it is likely that it is not the same person."

"How do you know for sure? What kind of zombie spotted flies grow like that? ”

Yang Tashan couldn't help but smile: "A lonely head with no joints, where did the corpse mortis check come from?" However, what you said about other corpse spotted flies and maggots is right, that is, it is to be judged according to the degree of [***] of the head, the corpse spots and the maggots on the skull. The maggot growth stage and the length of the longest maggot are also about the same as the maggot on the corpse, so it can be further judged that this skull is the same as the corpse. In addition, there is a blood group exclusion test ......"

Yang Tashan stopped when he said this, he subconsciously seemed to have a concept that his detection technique could not be told to others casually, but he couldn't remember who warned him about this.

Of course, Cheng Ziqin didn't understand the meaning of blood type, and when he saw that he didn't say anything halfway, he asked, "You are really troublesome, what kind of blood type test?" How to babble and spit out half of what you say and don't say half of it. ”

"This ...... This ...... is even more complicated, and it may not be enough for three days and two nights, so let me think about where to start......"

"Forget it! I'm too lazy to listen to your verbosity, and I still don't understand your verbosity anyway. Go on. ”

Yang Tashan smiled and said, "Since this head is preliminarily judged to be the same person as the corpse, then it should be a female surname." Cheng Catcher, do you see anything on this head? ”

As soon as Cheng Ziqin looked at this head, his eyes would involuntarily fall on the hole in the skull's eyes full of flies and maggots, and his body couldn't help but shiver, he didn't dare to look at it anymore, and shook his head: "No...... I don't see anything. ”

"Huh? Didn't you just judge that this female corpse was killed? Now that there is an important piece of evidence on the skull that supports your point of view, why can't you see it? ”

Hearing Yang Tashan's words, Cheng Ziqin stubbornly took a closer look, but still only saw a head full of wriggling flies and maggots, she wanted to find a small stick to remove those fly maggots to take a look, but before he did this, just thinking about it was enough for her to be nauseous and stomach-turning.

Cheng Ziqin said: "Don't sell Guanzi, tell me what you find out?" ”

Yang Tashan said: "This human head has obvious trauma, and there is only one trauma, which is in the left temporal region, which is in the shape of a long diamond. ”

Cheng Ziqin sighed, plucked up the courage to look at the left temporal part of the dead man, only to see a pile of maggots, where can I see any wounds.

Yang Tashan saw her doubts, and gently used a probe to push away the pile of fly maggots in the left temporal region, revealing a long diamond-shaped wound below, and said: "This wound should be the fatal wound of the deceased, this wound is very strong, and it has caused the long strip of skull to be shattered, the surname is depressed, the surname is fractured, the brain is contusion, and the brain tissue is partially overflowing. The deceased suffered this wound and should have died soon or even on the spot. However, this wound suicide can be formed, of course, under normal circumstances, he may kill a larger surname. ”

Cheng Ziqin was a little impressed and asked, "How do you know that there will be wounds under this pile of maggots?" ”

"Flies prefer to lay their eggs in open places such as eyes, nose, mouth, ears, etc., preferring to lay eggs in open wounds, but not in smooth skin without wounds. Therefore, if there is no wound on the temporal part of this person's head, there will definitely not be so many maggots accumulated, and it is in a long strip, so I judge that there must be a wound underneath. Although there are wounds on the head and face and other places, there are not so many maggots that have accumulated, and when I turned my head just now, most of the maggots in those wounds have fallen, and I can see that the wounds are very shallow and small. ”

"Isn't a small wound fatal?"

"That's not what it means, because those wounds are very shallow, and I have just examined them, they are all superficial lacerations on the skin, and they do not hurt the skull, so the preliminary judgment is that they are not fatal injuries. Of course, to confirm this judgment, it must be further tested. ”
