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

Chapter 377 Determining the identity of the deceased

Based on extensive experience in investigating previous cases, after a murderer commits a crime and kills someone, those who handle the body nearby will generally choose to bury the body, while those who handle it far away will generally choose to abandon the body.

This is due to the natural laws of human psychology. Most people have a natural sense of security close to home.

Being relatively familiar with the geographical conditions and the flow of people near the place of residence, the time for burying corpses is more leisurely, and the location is easier to choose.

But long-distance dumping is different. The murderer dumps the body at a long distance and usually does it quickly and subconsciously. Because the murderer is not familiar with the local situation and is afraid of being discovered by others, he will finish dumping the body in the shortest time and then leave.

It is extremely rare for the murderer to find a strange location that he has never been to before, dig a hole and bury the body.

However, there are always exceptions to everything.

Ren Qiang shook his head.

"Not necessarily. You forgot to report the case in Qinzhou five years ago. The murderer dumped the body at the door of his house."

"Everyone's guess at that time was to dump the body far away and bury it nearby. But in the end, the murderer dumped the body at the door of the house."

But no matter what the murderer's situation is, the clues obtained from the interviews and investigations are extremely limited.

The smell of Cangfanggou landfill is very strong. Normally, nearby villagers will not come here. Only some scavengers come here to pick up things.

Moreover, there is no surveillance in this place. If the murderer comes at night, no one will be able to discover it.

"How's the missing persons comparison going?"

"We have compared the recent missing persons in our city. If we don't find any, we'll have to look at the current investigation."

Although parts of the deceased's body were moldy, his face was still identifiable.

As soon as the body was discovered, the staff of the Criminal Investigation Detachment collected the deceased's face and compared it with the recently missing persons in Haizhou City, but unfortunately nothing was found.

There are two possibilities, one is that the family of the deceased did not report missing, the other is that the other party is not among the missing persons in Haizhou City.

The deceased had a valuable diamond ring on his hand, and the gold necklace around his neck was also suspected to be a famous brand, which showed that the deceased's family conditions were relatively favorable.

Generally speaking, it is unlikely that such a person disappears but is not reported missing.

Ren Qiang believes that the other party is most likely to be a missing person from another city.

But there is nothing we can do now, the appearance is not comparable, we can only wait for the fingerprint analysis or DNA identification from the current investigation.

Forensic laboratory.

"It was confirmed that there was a second occurrence of mildew, and the types of mold were different."

This was the first time Shen Yan saw a moldy corpse. She had seen it on videos before.

So, this is a unique learning opportunity.

"There have been fewer moldy corpses in recent years. In the past, there were a lot of moldy corpses."

Wang Changjiang sighed while doing the inspection.

"In the past ten or twenty years, the living environment was relatively poor. Unlike today, where everyone lives in buildings, the humidity was relatively high when we lived in bungalows. Most houses were relatively humid. Mildew may occur within a few days after a person dies. .”

“Now, if it rots, it doesn’t necessarily turn into mold.”

"Xiao Shen, come here and take a look. These moldy spots are the focus of our inspection, because they may cover wounds or other traces."

"Look below the hyphae, there is a layer of sticky gray stuff. That is dead hyphae..."

"Let's do some testing to see what this kind of mycelium is. It's most likely mold that occurred during the refrigeration process..."

"However, if it is mold caused by refrigeration...then the time of death is unlikely to be one month. The details will depend on the test results..."

In most cases, the possibility of mildew in refrigeration is relatively small, unless the temperature of the refrigerated environment is not low enough and the hygiene is poor.

But if the corpse is to be refrigerated for mold to occur, the time must not be short.But the body found in the garbage dump had a relatively low degree of decay, probably less than a month old.

Of course, this is because the body was sealed in the suitcase and covered with garbage. Otherwise, it would have rotted away.

"Let's do an autopsy and see if we can determine the time of death through organ changes."

The judgment of the time of death of a corpse is a comprehensive judgment.

Generally speaking, the time of death can be judged by surface conditions such as corpse spots and rigor mortis.

For corpses that have been dead for a long time, it can be judged by the decay of the corpse or the intergenerational growth of maggots.

The most troublesome thing for forensic doctors is to determine the time of death of refrigerated corpses.

Just like the corpse in front of me.

The body has become moldy, but the mold occurred in the landfill. Based on this, we can judge the time when the body was thawed, which was about one month ago.

But what about the time of death?
a year?
two years?

There were grid-like indentations on the back of the body, but no body spots, indicating that the deceased was not frozen immediately after death.

It is frozen after the corpse spots have disappeared and rigor mortis has ceased to exist.

And judging from the dismembered thighs and arms, the murderer did this to facilitate the dismemberment of the body.

But how long was it frozen in between...

Judging from the mold development during the freezing process, it will take at least half a year.

Otherwise, less than this time, it is difficult for the corpse to become moldy in the refrigerated state.

Wang Changjiang's autopsy judgment was confirmed by Lu Chuan's fingerprint identification analysis.

The fingerprints of the deceased were successfully compared and the identity of the other party was determined.

Wang Lili, female, 32 years old, from Huangzhou City, was reported missing in March last year and has been missing for one year and three months now.

As soon as the deceased's identity information was confirmed, Lu Chuan sent it out.

There are also fingerprints on the box, left by scavengers.

"You're actually from Huangzhou?"

Ren Qiang was a little surprised when he got the information.

After the identity of the deceased was not successfully compared with the missing persons in Haizhou City, Ren Qiang guessed that the person might be from another city, but he did not expect that he was from Huangzhou.

Huangzhou is not a few hundred kilometers away from Haizhou City, but thousands of kilometers away.

How could the murderer do it at such a long distance?
If a missing person was reported in Huangzhou, it means that Wang Lili disappeared in Huangzhou, and the place where she was killed was most likely in Huangzhou.

Huangzhou kills people, and Haizhou City dumps their bodies. Isn't this a bit far away?
Tonight is destined to be a sleepless night. The forensic doctor is continuing to perform autopsies and study the time of death of the deceased.

The cause of death was very clear, which was death caused by puncture of the chest with a sharp instrument.

But the time of death...

The time of disappearance does not mean that the person died at that time.

After Lu Chuan compared the fingerprints and determined the identity of the other party, he went to the basement to help.

Lao Bai's DNA identification is nearing completion, and the results will be available soon, which can then be used to support Sichuan's fingerprint identification.

The process is more complicated, and what is more troublesome is the analysis experiment of trace physical evidence.
