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

Chapter 384 Escalation of Case
In just one afternoon, a forklift digging into the dump unearthed a large black suitcase.

The cautious staff did not open it privately. The discovery of the first body made everyone feel a strange fear of the black suitcase.

Liu Guodong from the current investigation office led a team, and forensic doctor Wang Changjiang and others rushed to the scene immediately.

The experienced Liu Guodong and Wang Changjiang knew they had made another discovery by smelling the smell nearby without opening their suitcases.

The stench of corpses is different from most rotting stenches.

This is a very comprehensive and very special flavor, the kind of flavor you will never forget after smelling it once.

Some forensic doctors or forensic experts who are extremely experienced are said to be able to roughly determine the time of decomposition of a body simply by smelling it, combined with the environment at the scene where the body was found.

Lu Chuan's intermediate spot survey skills are introduced in this aspect, but he does not have this skill reserve. He should only have it when he reaches the advanced level.

"Lao Bai, you take pictures and I'll unpack them."

Although the box has not been opened yet, the unique putrid smell of the corpse has made everyone confirm that there is a corpse inside.

Strangely, the putrid smell of human corpses is different from that of animals, and the difference is quite obvious.

The on-the-spot photography of the exterior was quickly completed.

Liu Guodong put on three layers of gloves and prepared to unpack.

Hey!
The moment the chain was pulled open and Liu Guodong opened the lid of the box, the faces of the people who saw the situation inside were all extremely ugly.

Compared to Wang Lili's merely moldy corpse, this corpse could no longer be described as rotten, and some of its body parts had begun to melt.

The autolysis phenomenon of corpses is actually the degradation process of cells themselves.

After death, the cells of the human body lose their activity. Under the action of various enzymes, the cells begin to degrade, which can cause softening or liquefaction of organs and skin.

"Part of the skin has already undergone autolysis. The body was abandoned... at least two or three months ago."

The autopsy of a corpse follows a sequence. Generally speaking, the organs are the first to undergo autolysis.

The pancreas in the human body will undergo cell structural changes six or seven hours after the death of the human body. First it becomes swollen, and then the boundaries of the cells themselves gradually disappear, the color becomes transparent, and the entire state is liquefied.

Later, autolysis occurred in the lungs, heart, spleen, kidneys, etc.

The latest organ to exhibit this phenomenon is the liver.

Theoretically, the autolysis of corpses is not controlled by environmental pollution. That is to say, even if the corpse is in an absolute vacuum environment, as long as the temperature is appropriate, autolysis will still occur.

This is a phenomenon explained by the cells themselves.

The reality is that there are many bacteria present in complex environments, and these bacteria can promote the advancement of autolysis to a certain extent.

The most important thing is the influence of temperature. Extreme low temperature can greatly delay the autolysis process of corpses. Organs that originally took a few days to complete autolysis can even be preserved at low temperatures for hundreds of years.

The natural environment of the garbage dump will obviously accelerate the occurrence of autolysis.

wow.

The suitcase was opened, and a pool of corpse water flowed out.

The formation of corpse water is actually caused by microorganisms changing the sugar and protein in the corpse through dehydration during the decay process of the corpse. This dehydrated water is the main source of corpse water.

Because corpse water contains a large number of microorganisms and various decomposition substances produced during the decay of corpses, corpse water is toxic.

Unprotected contact can lead to infection.

Carefully collecting part of the corpse water, enough for a just-in-case toxicological analysis, several people began to clean the corpses in the box. "The limbs, torso, five parts were dismembered in the same way as the previous corpse."

Although if a body is found here, it can basically be concluded that the same murderer committed the crime, but as a forensic investigator and forensic doctor, we must make a basis-informed inference through judgment and analysis.

Wang Changjiang nodded and flipped the thigh bone with some tissue components stuck on it: "The dismemberment method is similar, clean and neat... Wait a minute, here!"

There was a scratch on the dismembered joint of the right arm.

There was also a scratch on the direct joint of the left arm.

"The techniques are the same, and there are signs of progress accumulated through experience..."

"This man... killed more than one or two people."

Liu Guodong studied and observed by himself and indeed found traces on the bones.

Just like primary school students practicing calligraphy, from the initial crookedness to the final neat handwriting, it takes practice, time and process.

The same goes for killing people.

The murderer dismembered the corpse. If it were just a corpse, it would be unlikely that the dismemberment would be perfect and smooth, like a cook dismembering a cow without any flaws.

In the actual process of solving a crime, traces of dismembered corpses can be found, which can determine the murderer's learning trajectory.

This second corpse obviously has traces of this.

"Let's carry it back first and do an autopsy to see what's going on."

Liu Guodong sighed. Most of the corpse had turned into water, and many traces had long since disappeared.

For example, the cause of death was autolysis of the corpse. The skin had almost disappeared, leaving only some residual tissue hanging on the bones. There was no way to judge the cause of death from the injuries on the corpse's surface.

If the other party's method of killing did not damage the bones, basically you really don't know how the other party killed.

In this case, what the forensic doctor can do is actually very limited. Apart from some analysis of the bones, there is basically nothing more that can be done.

The most important thing is to determine the identity of the deceased.

In this regard, there are some methods in the current investigation. Although the corpse appears to be highly decomposed and in a liquefied state, it is still possible to extract the DNA information of the other party through DNA identification and analysis.

However, the process may be cumbersome and time-consuming, and general methods may not necessarily work because the autolytic cells of the corpse degrade themselves and the genetic material in them has long since disappeared.

You can only look at the bone marrow, or extract mitochondria for DNA identification.

If that doesn't work, you'll have to rely on bones.

For example, whether the other party has broken bones or had any teeth implanted? These traces will leave clues even if the corpse is completely decomposed.

After Qin Yong roughly understood some basic information here, he turned around and got in the car and went to the municipal level to report to the director in person.

Big case.

Qin Yong felt very strongly that this must be a major case. The murderer's methods were cruel and there was a high probability that more than one or two people were killed.

Here at the garbage dump, the excavation master has been replaced by another person. The one just now couldn't stand it anymore and vomited bile.

But there is no way. Now that the second body has been discovered, no one can guarantee that there is no third body.

Lao Bai stayed and watched in case the third body was discovered, and the others returned to the detachment to examine the second body.
