Although each case of dumping corpses has its own characteristics, in summary there are rules.
When Lu Chuan was in the Criminal Investigation Detachment, he specialized in cases in this area.
Among all murder cases, murder is actually relatively simple. The key point is how to dispose of the body.
The most fundamental reason for the detection of all cases of corpse destruction and trace elimination is that the corpse destruction and trace elimination was not thorough enough.
The murderer left some clues in the process, allowing the police to grasp the clue and find evidence.
The murderer's behavior of dumping the body during this case was actually a bit strange.
There are many kitchen trash cans throughout the alley, as well as some large trash cans.
Chen Shuxian picked up the black bag next to a trash can.
And there are some sweet noodle sauce, ginger, garlic and other condiments in it.
During the subsequent inspection, Lu Chuan and others discovered that there were also some condiments in the other 12 black plastic bags.
Why?
The murderer deliberately put these condiments in the bag, is it to make people think that these things are ordinary meat?
Thus achieving the purpose of confusing the fish with the eyes.
However, the murderer did not expect that someone would pick up the meat and take it home to eat, and he discovered a problem.
This possibility exists.
After all, the other party cuts the bones just like ordinary big bones.
Bring some meat, just in time to make soup.
But in Lu Chuan's view, the murderer clearly had a better choice when dealing with these fragments.
For example, getting it into kitchen waste.
If the other party throws these pieces directly into the kitchen waste, no one will look for it, and no one will dig through it.
Even if someone saw it, they would definitely think that these were just leftover meat.
But the other party did not do this.
Instead, I chose to put the broken pieces in black plastic bags and throw them away.
Based on the location where the other party dumped the body and the cutting of the bones, there are traces of cutting by an osteocutter.
Lu Chuan speculated that it was a chef from a nearby restaurant.
But judging from the way the other party threw the body, it didn't look like it.
Walking into the alley, Lu Chuan raised his head and looked to both sides.
There are no surveillance cameras here.
None.
Is this the reason why the murderer dumped his body here?
Lu Chuan quickly walked from one end of the 200-meter-long alley to the other.
Not found.
Nothing.
With a sigh, Lu Chuan could only return to the criminal police brigade.
Just in time, when he went back, all the DNA test results came out.
"Team Lu, I wanted to call you just now. The DNA test results are out. Take a look."
As soon as he entered the door, Lu Chuan met Chen Jiang, who handed the report to Lu Chuan.
Chen Jiang looked a little excited: "There are some discoveries."
There are more than a dozen reports.
The plastic bags containing each broken piece were taken for DNA testing.
Although the splicing has now been completed, the forensic doctor confirmed that the deceased was the same person, and these fragments were not missing.
However, DNA identification can support the forensic judgment from another level.
Lu Chuan was focused on the two hairs, one long and one short, that he found inside the plastic bag.
Two reports, the one with long hair showed that it was consistent with the DNA identification results of the fragments.
That is to say, the long hair belongs to the victim.
But the DNA identification report on short hair is not that of the victim.
A short hair was found in the plastic bag containing the body fragments of the deceased. The hair did not belong to the deceased. So whose short hair belonged to him?
"Have you compared it?" Chen Jiang of the Second Squadron shook his head: "It has been compared. There is no DNA information about this person in the system."
No... …
Although there are not many people in the DNA information database now, those who have criminal records within ten years basically have information in it.
If the comparison is not successful, does it most likely mean that the other party has not committed any crime?
However, from the current point of view, this is absolute evidence.
From the perspective of the conventional crime-solving process, as long as the identity of the deceased is confirmed, DNA information of everyone around is collected based on the relationship between the person and the person, and then compared with the short hair.
As long as the comparison is successful, it means that the subject of the successful comparison may be the criminal suspect.
So now the problem is back to the beginning, confirming the identity of the deceased.
"Expand the scope of comparison, and check everything in the province except our city."
"Okay, I will make arrangements right away."
At the same time .
Wang Zhaokai of the No. 1 Squadron is inspecting entertainment venues one by one within his jurisdiction.
The High-tech Zone is an important engine for the economic development of the entire Haizhou City.
The economy is developing rapidly and the level of the service industry is relatively high.
The high-tech zone has the most bathhouses, KTVs, rocking bars and nightclubs in any zone.
Lu Chuan asked Wang Zhaokai to investigate these entertainment places. In fact, he did not mean to check all such places.
First of all, let’s not talk about whether there are so many manpower and material resources.
There was not enough time either.
So Wang Zhaokai’s places for platooning are some of the specific places.
The deceased was between 30 and 40 years old.
Whether they are beautiful or not, women of this age group generally rarely work in nightclubs.
In large bathing places, the jobs of these people are relatively stable.
If a person disappears for no apparent reason, a report will be made.
There are only some smaller entertainment venues, such as KTV and foot bath shops.
There are some people wandering around in places like this. They come and go tomorrow, but no one pays attention to them.
This is the place where Wang Zhaokai focuses his investigation.
However, the head of the deceased has not been found yet. Wang Zhaokai cannot ask you if anyone is missing.
There are so many missing people.
So, the work was not going smoothly.
On the other hand, Sun Biao of the Third Squadron investigated faster.
First of all, there were several restaurants near where the body was found. Sun Biao and others conducted a detailed search of all the staff in the kitchen.
But these people were quickly ruled out as suspects.
Because these hotels are located in prosperous areas, business is generally good.
Every night all the chefs are basically very busy.
And their off-duty time is around 11:00~12:00.
If the murderer was one of them, there would be no time for dismemberment.
In addition, the chefs of these hotels are actually a team with relatively strict management.
Everyone has their own work tasks, and there are many people.
There were as many as twenty people, and as few as three or five.
If someone throws a dozen black plastic bags outside, there is a high probability that his companions will notice it.
Of course, it can only be said that the suspicion of these people is relatively small, but it cannot be said to be completely ruled out.
During the investigation, it was found that some hotel chefs had taken leave. Sun Biao has arranged for people to investigate, but no results have been reported yet.
In addition, there is a survey about tattoo shops. (End of this chapter)
