What facts? Cheng Ziqin asked.

"Although the broken neck has been destroyed by malfunctioning maggots, it is not clear whether it is a sharp weapon, but the traces from other places can help us figure out this problem."

Yang Tashan used a probe to cut the marvelous marshes on his neck, revealing half of the remaining neck, which was covered with marshes protein dissolved enzyme digestive fluid etching through the holes. He inserted several holes into them with a probe and said: "Please note that the size and depth of these holes are different from the size and depth of these holes formed by worms. This is formed by the teeth of wild dogs. And-"

The probe was inconvenient, so Yang Tashan simply used his hand to separate the corroded soft tissue at the fracture of the neck and spine, exposing the cervical vertebrae, wiped the spine clean with the back of the deerskin gloves, and pointed to a few small scratches on the vertebrae arch: "Please note that this scratch is curved, and it is absolutely impossible to be a knife or other chopper forming a ground."

"That's right, it's wild dogs and other animals bit the ground." This time the ground traces were obvious, and Cheng Ziqin no longer argued with Yang Tashan.

Yang Tashan dug open the wounds on the breasts and thighs and said, "Please pay attention to the head catcher. Although the wound walls of these wounds are also damaged by magnies, the general shape of the wounds can still be distinguished. If you cut them with a knife, it is difficult to form such wounds, especially those on the wounds on the thighs. This should be the wild dog biting the flesh on the corpse and pulling it off."

"Does the wild dog or the jackal have that strong power?"

"Don't underestimate the ability of wild dogs to bite. Especially when the corpse is already highly corrupt, the muscle tissue is like blunt braised pork. The wild dog can easily tear off large pieces of muscles and break the cervical spine of the human ground. However, it is not difficult for a group of wild dogs."

Cheng Ziqin couldn't help but feel stomach-breaking. I don't know if it was because of the stinky corpse or Yang Tashan's statement was too disgusting.

Cheng Ziqin frowned and said, "Okay, even if you are right. It's a wild dog or a jackal who tore off her head. Then how did this person die? Have you found out?"

Yang Tashan shook his head: "No, I just carefully examined all the wounds on the headless corpse, and found no obvious fatal injuries. These wounds were all formed by biting wild dogs. Although the corpse was full of wounds, no traces of him killing the ground were found."

"Then, is it suicide? It's impossible!" Cheng Ziqin said.

"I didn't say it was suicide. I mean there has not been sufficient evidence to prove the cause of the woman's death."

Cheng Ziqin also agreed with this and asked, "What should I do now?"

"First, try to find the deceased's head. If we make a good judgment, it is a wild dog biting the land head, then the head should be nearby; second, determine the source of the corpse and find out who the deceased is; third, find the first scene of the death site. Only by confirming that this person is actually killed by murder will our land detect it."

Cheng Ziqin nodded, stood up and said loudly to the constables standing not far away: "You will search this area online to find the headless female corpse, and then see if there are any dresses or other suspicious items."

Luo Yi and other constables agreed, lined up in a long row, and slowly conducted a dragnet-style search.

Cheng Ziqin asked again: "How can we find this first scene?"

Yang Tashan smiled bitterly: "I don't know this." He stood up, looked around, and continued: "When they searched first, see if they found out. Perhaps the first scene was near Pingtougou, or maybe someone moved the body here in Qingyang City or nearby villages."

Then Yang Tashan walked to his forensic physical evidence investigation box, took out two small bottles from it, returned to the corpse, and picked some maggots from each wound. He put them into two small bottles.

Seeing this scene, Cheng Ziqin was both disgusting and curious, frowned and asked, "What are you doing with these maggots?"

"Take it back and raise it."

"Ah!" Cheng Ziqin shouted in surprise, looking at Yang Tashan in horror. She couldn't believe that Yang Tashan had such a perverted hobby.

Yang Tashan smiled: "Don't underestimate these maggots. As long as you treat them well, they can tell you a lot of things you want to know."

Cheng Ziqin felt a little furious when she heard it, and asked, "What can they tell?"

"For example, when did this deceased die?"

"How do you know this...?"

"As soon as a person dies, he will produce a scent of decay. Although the scent of the earth cannot be sensitively captured by the human nose, the flies already know it. They will soon find the corpse and start laying eggs on the corpse. Then, beetles, parasitic bees, mites, turtles, and moths will also come to the corpse one after another. There is a certain pattern in the appearance of these insects.

, we can respond to the time when the deceased dies according to the law of the appearance of these insects

When Cheng Ziqin heard that he was so mysterious, she hurriedly asked: "What are the rules for these insects to appear?"

"There are many species of flies alone. Each type of flies has different preferences for corpses. Some prefer fresh corpses and some prefer corrupt corpses. Simply put, generally, two days after a person dies, there will be lying flies and thora flies on the corpses. They will lay eggs on the eyes, nose, ears, throat, vagina, door and wounds of the corpses."

"Why don't the other flies come?"

"Because other flies like corpses with serious or even highly corrupt corruption, they are not interested in fresh corpses, so they won't come."

Cheng Ziqin heard that there was so much knowledge here, and was even more curious and asked, "Why will the fly come after the corpse is corrupt?"

"Two to seven days after death, the corpses exposed in the air have begun to enter a period of severe corruption. At this time, in addition to liflies and sausage flies, they will also fly to lay eggs. Four to thirteen days after death, most of the soft tissues of the corpses have been eaten by fly larvae. At this time, the corpses have been highly corrupt, which has attracted a large number of sausage and predatory beetles. In the later stage of this stage, the larvae of Liflies and sausage flies have left the corpse and turned into pupae."

Cheng Ziqin's brows were almost frowning, and listening to Yang Tashan's dialect, his stomach churned.

Yang Tashan smiled and continued, "When the 10th to 23rd day, the flesh of the corpse will be almost eaten up, leaving only hair, skin and cartilage. These are insects such as flies and are not interested, so they left one after another. However, all kinds of beetles like it very much. At this time, they will come to the remaining corpses in large numbers. After they eat all their favorite things and leave, the corpse will have nothing to eat. However, there are still animals next to the corpse."

Cheng Ziqin tried hard to suppress her stomach and said, "The body and the ground are all eaten up, so what insects are there?"

It can last for three months.”

Cheng Ziqin used to only see maggots or pupas on the corpse, and she didn't think about the rules of the appearance of these things, nor did she associate them with the time of death. Now, after hearing Yang Tashan say that, she suddenly realized and said, "According to you, as long as you find some insects on the corpse, you will roughly know the time of the deceased's death?"

"Yes! My two bottles, one is a storage cup for storage liquid and the other is a feeding cup. I put these maggots back to cultivate them into adults. On the one hand, I look at what kind of flies these maggots are, and on the other hand, I look at the time of their growth, so as to infer the death time of the deceased. Once the death time is accurately judged, it can provide a basis for us to determine and eliminate criminal suspects in the future."

After all, Cheng Ziqin is a family of constables, and her father is an old captain, so of course she knows the importance of determining the death incident to solve the case. She asked: "You just said that it was a time period. How do you use to know when it is exactly?"

"Of course there is a way." Yang Tashan said, "For example, in this case, the corpse is already highly corrupt, and the speed of the corpse is greatly affected by the temperature. According to the current hot weather conditions, it only takes two days to reach this step, so it is initially judged that the death time is more than two days. I just moved the joints of the corpse and found that the corpse zombie has been completely relieved. From this, it is judged that at least four days have passed since death..."

"Wait!" Cheng Ziqin blinked her eyes, "What did you say just now to relieve zombie zombies? What's going on?"

"The zombie is the zombie stiffness..."

"You don't need to say this, I know!" Cheng Ziqin was angry that she was despised. After all, she was a family of constables. She still knew that this person would become stiff after death, "I'm asking you, you just said that by completely quenching the zombie zombie, you can infer that it had been four days since death. What's going on?"

"A person will be stiff after death, and this stiffness is also regular." Yang Tashan explained patiently, "Generally speaking, corpse zombies appear about one hour after death, four hours will expand to the whole body, and it will start to relieve in two days, and it will be completely relieved in three to four days. Therefore, I just moved the joints of the corpse and found that the corpse zombies have been completely relieved, so I got the preliminary judgment of the four heavens and earth of death."

"You mean, based on the comprehensive judgment of the corpse corruption and zombie zombie, this person has been dead for at least four days?"

"Yes, but this is only the minimum time of death, not the exact time. To determine the exact time of death, more evidence must be found."
