noon.
Criminal Investigation Detachment No. 1 Conference Room.
"Brother Qiang, we have a clue!"
Zhang Hui was in high spirits and expressed excitement: "Tan Zhongfa and the Wang family do have friction and disputes."
"It started five years ago..."
Zhang Hui summarized and analyzed what he learned.
"Five years ago, the vineyards in Beitun Village were re-divided into contracted areas and the size of the land was measured. Due to motorized farming, the vineyards adjacent to the Wang family and Tian family had half an extra ridge."
"The two families had a dispute over this half of the ridge, and Tian Zhongfa and Wang Chengshun, Wang Zihao's father, got into a fight."
"At that time, it was the village party secretary who made adjustments, and Wang Chengshun compensated Tian Zhongfa 2,000 yuan for medical expenses."
"But the disagreement over half of the ridge was never resolved. The two families took turns planting, one family for a year."
"Last year, Wang's wife took turns planting, but she didn't send any seeds to Tianzhong this year."
"Although the relationship between the two families appears to be good, in fact it is almost on the same level."
"In addition, Tian Zhongfa's family lives in the west end of the village. If he arrests Wang Zihan, he can go home directly and it will be difficult for other people in the village to find out."
"One more thing, I heard from Tian Zhongfa's neighbors that Tian Zhongfa used to wear an old blue work clothes. He just changed into new clothes three days ago, the day after the child disappeared."
Clothes, neighborhood conflicts, with these few things in mind, Tanaka's suspicions increased greatly.
"Brother Qiang, are you going to catch me?"
"Why are you hesitating? Catch me!"
trial room.
Tanaka, wearing brand new blue overalls, sat on the interrogation chair without saying a word.
"Tanakafa, do you recognize this dress?"
After arresting Tian Zhongfa, Zhang Hui conducted a careful search of Tian Zhongfa's home.
A red scarf was found in the side room where Tanaka's wife was locked.
In the bedroom cupboard, an old blue coverall was found.
Upon closer inspection, hair and dander were found.
Lu Chuan is doing DNA identification and analysis. If these hairs and dander belong to Wang Zihan, it means that Tanaka Fa is indeed the murderer.
What's more, there was the red scarf found in the wing.
"Tan Zhongfa, the red scarf found in the wing of your house is being examined. Hair and dander were also found on the old clothes you changed into."
"I hope you can explain clearly before the results come out. This can be considered a frank confession."
"When the results come out, even if you don't say anything, you will still be convicted!"
"I...I said..."
Tanaka's hands trembled, and he began to confess with choked sobs: "That day... I was indeed the one who caught the child."
"But...killing him was an accident..."
Faced with the police's questioning and sitting under the spotlight, how could a farmer in the field be able to bear it?
After a while, everything was said.
It turns out that Tian Zhong arrested Wang Zihan just to ask the Wang family to return half of the ridge to him.
"That land originally belonged to my family, but Wang Chengshun's wife insisted on occupying it. That year, after the village party secretary completed the adjustment, I thought about giving in."
"My family has been planting for a year, but after his family finished planting last year, when they were preparing the field today, they had to bury the grape trellis again..."
"I really didn't want to kill the children, I just wanted to scare them... Wuwu..."
"That child... I also watched him grow up..."
"Then why did the child die again?"
"Yes... yes... my wife..."
"That day, after I caught Wang Zihan, I tied him and gagged him, and locked him up in the wing of my house. I was afraid that others would find him, so I went out to work."
"But I didn't expect that when I came back in the afternoon, the child was dead and half of his ear was bitten off by my wife..."
"I really didn't mean it. I was in a hurry to go out in the morning and didn't feed her..."
"The corpse is dumped
? "
"In the middle of the night, I went to dump the body and dumped it in the No. 3 engine shaft..."
The interrogation here is not over yet, and the identification results from Lu Chuan's side have also come out.
There are blood stains on the red scarf from Wang Zihan's ear being bitten, and his blood type is consistent with Wang Zihan's.
The shabby blue work clothes that Tanaka found in the cabinet had thin silk threads scattered around the cuffs. The fibers found at the scene should be from the cuffs.
Some of the dandruff on his body comes from Tanaka's hair, his wife's, and Wang Zihan's.
"Ding!"
"Advanced mission completed: The host and colleagues worked together to determine the first scene of the crime and found key clues to identify the suspect. Through experimental analysis of fibers, the task force successfully helped the task force identify the suspect."
"System reward: Forensic Entomology Intermediate Skill Card, please host choose the skill type."
Forensic entomology?
When Lu Chuan was chatting with Shen Yan, he heard her talk about this branch of forensic medicine.
This is a subcategory that is relatively rarely studied in the field of forensic medicine.
Forensic entomology is a comprehensive subject that mainly determines and analyzes the time of death, cause of death, place of death and other information based on the growth of corpse-eating flies, beetles and other insects.
There is also a more detailed division of capabilities under the forensic entomology category within the system.
For example, among the intermediate abilities, there are intermediate big-headed golden fly breeding skill cards and intermediate greenfly identification and analysis skill cards.
There are also intermediate maggot growth identification and analysis skill cards, intermediate white-bellied skin beetle character analysis skill cards, etc.
In forensic practice, analysis of insects or eggs parasitic on corpses can provide forensic doctors with a lot of information.
Especially on highly decomposed corpses, where much of the surface information is missing, the analysis of corpse parasites can help criminal police grasp more clues to solve the case.
There are a wide variety of skills, and Lu Chuan needs to choose carefully.
You can't choose a skill for raising corpse flies, otherwise you will be at a huge loss.
In the end, Lu Chuan decided to choose the intermediate corpse egg identification and analysis skill card.
Intermediate corpse egg identification and analysis skills can accurately identify the type and growth level of parasite eggs on corpses.
After death, the odor produced by a body can attract a variety of insects.
Including flies, beetles, bees, butterflies or moths, among which flies are the first to be attracted to corpses.
Especially blow flies and lineflies. These two flies can find corpses and parasitize and lay eggs within ten minutes after a murder occurs.
The most important function of cadaver entomology, or the one most used in practice, is to determine the time of death of a corpse.
Most of the time is determined by collecting insect eggs from corpses and hatching them.
The hatching time of each type of insect eggs is fixed in different environments.
By simulating the ambient temperature and humidity of the crime scene and hatching insect eggs, the specific time when insects lay eggs on the corpse can be obtained.
By taking the difference between the standard hatching time of insect eggs and the actual hatching time, the specific time of death of the corpse can be obtained.
Lu Chuan's intermediate corpse egg identification and analysis skills can directly determine the type and growth level of the eggs, which is equivalent to directly determining the growth time of the eggs.
This is of great significance for determining the time of death.
