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

Chapter 179 A 1000-meter Road
Wang Changjiang and Shen Yan began to conduct further inspections on the corpse after Lu Chuan and others finished their investigation.

Different from the aspects that the current survey focuses on, the forensic doctor mainly judges the time and cause of death of the deceased through autopsy.

"According to the degree of swelling of the corpse's skin, the deceased had been soaked in water for more than 24 hours."

Depending on the soaking time of the corpse in water, the degree of skin swelling will vary.

Wang Changjiang is a veteran in this field. He has dissected many corpses with blisters before, and he is very experienced in judging the degree of skin swelling of corpses.

Shen Yan listened carefully and took notes carefully.

Unlike Lu Chuan's cheating, Shen Yan's learning is gradual, and she has learned a lot from Wang Changjiang in the past two years.

"The degree of immersion of the corpse mainly depends on the eyes and fingers."

Wang Changjiang also intentionally taught Shen Yan: "The eyes are the part that is most likely to get in water. After soaking in water, the color of the eyeballs will become cloudy and slightly convex."

"The skin of the fingers will appear water-absorbing folds after soaking in water for more than 10 minutes."

"Compared with the degree of swelling in other skin parts, you can judge the approximate time of blisters."

"Yeah," Shen Yan is obviously a good student who loves to learn. She records useful knowledge and asks questions from time to time: "Master, there are teeth bite marks on the left ear of the corpse. You said last time that if the corpse has wounds, after being soaked, the wounds can be used. How to judge the time of blistering according to the erosion condition of the water?”

Wang Changjiang twisted the head of the dead body: "Look here, the oozing spots of the blood stains have disappeared, and burrs have begun to appear on the edges. This is the characteristic of blisters for more than [-] hours."

"But the wound has not decomposed, which means that the blisters have been less than 48 hours."

Whether it is forensic medicine or current survey, they are all empirical studies.

Theory is important, but experience is more important.

With the same judgment standard, the change of the corpse will be different under different temperature, different humidity, or different indoor and outdoor conditions.

At this time, only by experiencing it can we make an accurate judgment.

"Cause of death... There are obvious pinch marks on the neck, purple lips, and blue and purple face. There are no other injuries. The cause of death is preliminarily determined to be mechanical asphyxiation."

The reason why Wang Changjiang was preliminarily determined was because the cause of death was finally determined, and an autopsy was needed before a final conclusion could be drawn.

However, whether the corpse should be dissected or not, the parents' opinions must be sought.

Most of the cases that Wang Changjiang has encountered over the years, in adult death cases, the family members will agree to autopsy.

Some family members of female corpses would disagree.

In cases of minor deaths, the vast majority of parents will not agree to an autopsy.

Of course, the premise of this is that the forensic doctor can issue an opinion on the time of death and the cause of death without dissection.

Family members must also sign the agreement.

For example, the deceased took some kind of medicine given by the murderer, such as sedatives, which cannot be found out without an autopsy.

After taking a sedative, he strangled to death, and the cause of death was still asphyxiation.

But in the sedative link, because the family members did not agree to the autopsy, an important clue was lost.

This may be the key to solving the case.

Therefore, both parties must sign and confirm.

"Combined with the rigor...the time of death is about 48 hours."

The child disappeared after going to school two mornings ago, and it was less than fifty hours since the body was found.

In other words, according to Wang Changjiang's judgment, the child was killed within an hour or two of leaving home.

But the soaking time is no more than 24 hours.

In other words, after the murderer killed the child, it took nearly a day and a night before throwing away the body.

So the specific time of dumping the body should be between last night and early this morning.

This judgment also corroborates the judgment of the present survey side, that the vicinity of the machine well is indeed not the scene of the first crime.

After the inspection results of the current survey and autopsy were reported to Qin Yong, all kinds of information gathered, and it was easy for Qin Yong to make the above judgment based on Qin Yong's experience.

"Old Liu, I have to work hard for you."

Turn on the phone navigation and zoom in on the nearby map.

"This is the child's home. Under normal circumstances, the child goes to school from here, along this road, and walks about two kilometers to Zirantun."

"But Zirantun's surveillance did not capture the child."

After the child was reported missing, the police from the Xijiao Police Station had scoured the monitor to make sure there was no trace of the child.

"That is to say, the places where the children disappeared are concentrated on a section of 2000 meters."

"After the murder, the murderer hid the body, and then dumped the body from last night to this morning."

"Check this section of the road and see if you can do a detailed site survey, maybe you can find clues."

Qin Yong also had the attitude of giving it a try.

Based on the current clues, it can be determined that the murderer did it on this 2000-meter section of the road.

But it's not just killing people on this road, I'm not sure.

The murderer is very likely to hijack first, then go to other places to kill, and then hide the body, and wait until night or early morning to throw the body in the dark.

"This section of the road, even if it's not the first scene, must be the first place where the murderer kidnapped the child, and..."

Qin Yong zoomed out on the map, revealing a deliberately marked red dot.

"This is the location of the well where the body was found, and it is about three kilometers away from the road where the child disappeared."

"The murderer will definitely hide the corpse after killing someone, Sun Jun!"

"To!"

"With the machine well as the center and a radius of five kilometers, check all the farmers living nearby!"

"Yes!"

"Ren Qiang, your group is responsible for investigating the situation of the children's parents. Do they have any enemies or people who have conflicts? I want to find out all the backgrounds of their families!"

"Yes!"

Three groups of men and horses, at full power, advancing on three fronts.

Grape picking in spring.

Most of the grapes Wang Zihan's parents grow are wine grapes.

But these years, in order to increase income, some table grapes are also planted near the road. When the autumn harvest is good, people from the city will come to pick them.

It's spring now, the ice and snow have just melted, grapes are still buried in the soil to keep warm, and there are only endless rows of cement piles on both sides of the road, like lonely wild ghosts, standing motionless in the field.

Starting from the vineyard where Wang Zihan lived, Lu Chuan, Liu Guodong and Lao Bai headed all the way west.

"Brother Bai, use this, the searchlight can find biological tissues that our naked eyes can't see."

This time, Lu Chuan and others can be said to be fully armed to the teeth.

Liu Guodong was holding a targeted biological trace detection device, and Lu Chuan was holding an ultra-wide spectrum on-site trace evidence search camera.

In Lao Bai's hands is the laser evidence detector that Lu Chuan just taught to use.

Looking at the spots that lit up on the screen from time to time, Lao Bai hurriedly collected the physical evidence he had searched.

"This thing works really well."

Grinning, Lao Bai felt a little emotional: "If there were such things in the past, there would still be so many backlogs."

"It's just... there are too many things I discovered..."
