Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 184 Manslaughter
noon.

Meeting Room No. [-] of the Criminal Investigation Detachment.

"Brother Qiang, we have a clue!"

Zhang Hui was in high spirits, with an excited expression on his face: "Tanaka Fa and the Wang family do have friction and disputes."

"It started five years ago..."

Zhang Hui made a summary analysis of what he had heard.

"Five years ago, the vineyards in Beitun Village re-divided the contracted area and measured the size of the land. Because of the mobile farming, the adjacent grape fields of the Wang family and the Tian family had half an extra ridge."

"Because of this half ridge, there was a dispute between the two families. Tian Zhongfa and Wang Chengshun, Wang Zihao's father, fought."

"Back then, it was the village secretary who made adjustments, and Wang Chengshun paid Tian Zhongfa 2000 yuan for medical expenses."

"However, the half ridge that had a disagreement at that time has not been resolved. The two plants are planted in turn, and the family is planted for a year."

"After the Wang family's daughter-in-law took turns planting last year, she did not send seeds to the field this year."

"Although the relationship between the two companies looks good on the surface, it's actually almost at the same level."

"In addition, Tian Zhongfa's family lives at the west end of the village. If he captured Wang Zihan, he can go home directly. It will be difficult for other people in the village to find out."

"One more thing. According to Tanaka's neighbors, Tanaka used to wear an old blue overalls. Three days ago, that is, the day after the child disappeared, he changed into new clothes."

Clothes, conflicts with neighbors, with these things, Tanaka's suspicion increased greatly.

"Brother Qiang, do you want to catch him or not?"

"Why are you hesitating, grab it!"

trial room.

Tanaka, who was wearing brand-new blue overalls, sat on the interrogation chair without saying a word.

"Tanaka, do you recognize this dress?"

After arresting Tian Zhongfa, Zhang Hui searched Tian Zhongfa's home carefully.

In the wing room where Tanaka's wife was locked, a red scarf was found.

In the bedroom cupboard, an old blue overalls were found.

Upon closer inspection, hair and dander were found.

Lu Chuan is doing DNA analysis. If the hair and dander belong to Wang Zihan, it means that Tian Zhongfa is indeed the murderer.

What's more, there is a red scarf found in the wing room.

"Tanaka Fa, the red scarf found in your wing room is undergoing inspection, and hair and dander were also found on the old clothes you changed."

"I hope you can explain clearly before the results come out, which can be regarded as a frank and proactive confession."

"When the result comes out, even if you don't say anything, you can still be convicted!"

"I...I said..."

With trembling hands, Tian Zhongfa began to explain with sobs: "That day...the child was indeed caught by me."

"But... killing him was an accident..."

Facing the police's questioning, sitting in the spotlight, Tian Zhongfa, a farmer, how can he bear it.

After a while, everything was said.

It turned out that Tian Zhongfa arrested Wang Zihan in order to let the Wang family return half of the ridge to him.

"That land was originally my family's, and it was Wang Chengshun's wife who insisted on occupying it. That year, after the village party secretary made adjustments, I thought about giving in."

"The family planted for a year, but after his family finished planting last year, when the field was being plowed today, the grape trellis was buried by him again..."

"I really didn't want to kill the children, I just wanted to frighten them... woo woo..."

"That child... I watched him grow up too..."

"Why did the child die again?"

"Yes... yes... my wife..."

"That day, after I caught Wang Zihan, tied him up, gagged him, and locked him in the wing of my house. I was afraid that others would find out, 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 my 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..."

"Where is the corpse?"

"In the middle of the night, I went to throw the body, and I threw it in the No. [-] machine shaft..."

The interrogation here is not over yet, and the results of Lu Chuan's appraisal have come out.

On the red scarf is the blood of Wang Zihan after his ear was bitten, and his blood type is the same as that of Wang Zihan.

The shabby blue overalls found in Tanaka's locker, the cuffs were bared, and thin silk threads were scattered. The fibers found at the scene should be left behind by the cuffs.

The dandruff on his body came from Tian Zhongfa, his wife, and Wang Zihan.

"Ding!"

"Advanced task completed: The host and colleagues worked together to determine the first scene of the crime, found the key clues to lock the suspect, and successfully helped the special case team lock the suspect through the experimental analysis of the fibers."

"System Reward: Forensic Entomology Intermediate Skill Card, please select the skill type from the host."

Forensic entomology?
When Lu Chuan was chatting with Shen Yan, he heard her mention this branch of forensic medicine.

This is a subcategory that is rarely studied in the field of forensic medicine.

Forensic entomology is a comprehensive discipline, mainly based on the growth of necrophagous flies, beetles and other insects on the corpse, to judge and analyze the death time, cause of death, death location and other information of the corpse.

Under the forensic entomology catalog in the system, there is a more detailed division of capabilities.

For example, among the intermediate abilities, there are intermediate golden fly breeding skill cards and intermediate Lucilia sericata identification and analysis skill cards.

There are also intermediate fly maggot growth identification and analysis skill cards, intermediate white-bellied dermatomid trait analysis skill cards, and so on.

In forensic practice, analysis of insects or eggs parasitized on corpses can provide a lot of information to forensics.

Especially on highly decomposed corpses, where information on many corpse sheets is missing, the analysis of parasites on corpses can help criminal police grasp more clues to solve the case.

There are so many kinds of skills, Lu Chuan has to choose carefully.

You can't choose a skill to breed corpse flies, then you will lose a lot.

In the end, Lu Chuan decided to choose the intermediate-level corpse egg identification and analysis skill card.

Intermediate dead body egg identification and analysis skills can accurately identify the type and growth degree of dead body parasitized eggs.

After death, the odor produced can attract a variety of insects.

Including flies, beetles, bees, butterflies or moths, among them, the flies are the first to be attracted by the corpse.

Especially the blowfly and the hemp fly, these two kinds of flies can find the dead body and parasitize and lay eggs within ten minutes after the murder.

The most important function of cadaver entomology, or the most used in practice, is to judge the time of death of the corpse.

Most of the judgment of this time is by collecting the eggs from the corpses and hatching them.

The hatching time of each kind of eggs is fixed in different environments.

By simulating the ambient temperature and humidity of the crime scene and hatching the eggs, the specific time when the insects lay eggs in the corpse can be obtained.

By making the difference between the standard hatching time of the eggs and the actual hatching time, the specific time of death of the corpse can be obtained.

However, Lu Chuan's intermediate-level corpse egg identification and analysis skills can directly determine the type and growth degree of the eggs, which is equivalent to directly judging the growth time of the eggs.

This is of great significance for judging the time of death.
