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

In all homicide cases, whether it is pre-planned or passionate killing, how to kill is often not the most important process.

The important process is how to dispose of the body after killing the person.

If the corpses could be completely destroyed and no traces of the people existed, there would naturally be no pre-existing question of how to kill people.

Buried in soil, hidden in water, or burned in fire, whether the murderer handled the body properly or not is often the most difficult point in solving a murder case.

Lu Chuan learned about such a case when he was in college.

Twenty years ago, there was a murder case. The murderer was the husband and the deceased was the wife.

The murderer killed his wife, dismembered her body, and then burned the body in the pit of his home.

The place where the murderer dismembered the body was located in the creek in front of the door. In order to prevent others from discovering the murderer, he carried out the operation at night.

Just do a little at a time.

Then while cooking, the body is burned.

This process lasted for more than a month before the body was disposed of.

But the disappearance was never reported.

It was the parents of the deceased who discovered the problem.

The parents of the deceased are not far from the deceased's home, only a dozen kilometers away. Normally, they would go back to their parents' home every two or three months.

Because the deceased did not return to her parents' home for half a year after she was killed, her parents came to look for her.

Only then did I realize that the person was missing.

Of course, the wife's husband became an important suspect, but during the subsequent investigation, a very difficult point was encountered when the murderer admitted that he had committed the murder.

But the evidence is gone.

The murderer strangled his wife to death. From this point of view, there was no murder weapon in the traditional sense.

The ax used to dismember the corpse was thrown into the molten iron by the other party while he was doing odd jobs in a small iron factory near the village, and it melted.

The criminal police investigating the case found no valuable clues in the murderer's stove pit. Time passed too long and the murderer had to dig out the ashes every morning.

Even if there were any remains of human tissue ashes, they were gone.

Moreover, after the murderer took out the pit ashes, he did not throw them into a specific place, but directly into the stream in front of the door, and washed away with the current.

This makes this case particularly peculiar.

Although the deceased was missing, it was not entirely certain that he had been killed because there was no body.

Death passed, and finally the murderer was revealed, but no rest was found.

It can be said that after the victim was killed, nothing was left behind.

In this case, the evidence chain cannot be connected and closed at all.

Therefore, even if the murderer admitted that he committed the murder and described the killing process, he still could not convict the other party during the trial.

After all, no one can be sure that what the murderer said is the truth.

Although this case did not completely eliminate the traces of the victim's body, the murderer used vacuum bags to package the body, which has the same purpose.

Of course, this method of handling corpses does not depend on whether the corpse can be found, but on leaving no traces or affecting the surrounding environment during the process of handling the corpse.

The body itself offered no further clues.

Wang Gang and the others have also done more detailed work here, and now everything that can be investigated has been completed.

The key is to look at the steel plate in the deceased's right arm to see if there are any clues to his identity.

Theoretically speaking, it is impossible for a person to live independently of this society. He will definitely get deeper into the surrounding environment or interact with other people.

If the identity cannot be found, it does not mean that the other party has no identity. It just shows that there is a problem with the police's method of finding identities.

In addition, based on normal experience, the murderer and the deceased must have known each other, otherwise the other party would not have sealed the body in a vacuum bag.

The purpose of burying the body is to prevent the police from investigating the deceased's interpersonal relationships to find the murderer.

Now Lu Chuan decided to investigate from two aspects.

The first is to expand the search area for missing persons.

Expand from this city to the whole province and even the whole country.

The second one is through the right arm of the deceased? Hello, the steel plate embedded inside, I want to investigate whether anyone in Haizhou City has done such an operation more than ten years ago.

Of course, there must be many cases of surgery for broken arms, but correspondingly, because the steel plate is implanted, it means that the fracture is more serious.

This is not something ordinary hospitals can do.

Therefore, there should be cases remaining.

Of course, the real problem is that the time of death of the deceased is not completely certain.

Guo Jianfeng, the forensic doctor of the Tianshan District Criminal Police Brigade, gave a judgment of ten years.

But that's just a range.

Lu Chuan just took a look and found that the deceased's death time should be between eight and twelve years.

But the problem is that this is just a death incident. Lu Chuan still needs to conduct further research on the circumstances of the murderer's fracture.

The time of fracture can be comprehensively judged based on the bone healing condition and the steel plate implanted inside.

But this requires time to do some experiments, and it will take at least one day to get the results.

Fortunately, this case is not particularly urgent. The person has been dead for so many years, and his identity has not been determined. To put it bluntly, there is no pursuit to solve the case.

Compared with the investigation and reasoning of solving crimes, Lu Chuan, as a criminal police officer with a background in investigation, actually prefers to do technical work.

Because there is only certainty in doing technical work, one is one, and two is two.

With directionality, if it works, it works, and if it doesn’t, it doesn’t work.

Guo Jianfeng has already taken out the steel plate, and Lu Chuan will take over the rest of the work.

But because neither the Tianshan District Criminal Police Brigade nor the High-tech Zone Criminal Police Brigade had relevant equipment, Lu Chuan could only take the things back to the Criminal Investigation Detachment.

The identification process is not troublesome. Based on the wear and tear of the steel plate and some marks on it, the time when the steel plate was implanted can be judged.

Coupled with the healing status of the bones, the time of bone healing can also be roughly judged.

Combining the two factors, Lu Chuan basically judged that the deceased's arm fracture should be three to five years after his death.

In this way, the time of the operation for the deceased's fracture was within the range of 11 to 16 years ago.

"This is not bad. When investigating some cases in our public hospitals, it took a long time for the data to leak out. But I am afraid that the other party did not do it in Haizhou City. If the operation is like that..."

This is what Wang Gang is worried about.

I am surprised that no matter how powerful this team is, it is impossible to go to all hospitals across the country to conduct investigations.

Therefore, if the other party had the surgery in Haizhou City, the problem would not be particularly big. If you spend more time, you may gain something.

If you are outside the city...

To be honest, there is really nothing we can do about it.

At that time, the only option is to archive the DNA information of the deceased and wait for comparison.

Of course, it’s hard to say whether or when the match will be successful. (End of chapter)
