In other words, this button may only be brought in by the deceased, not originally found in the cemetery.

The quality of the buttons is obviously excellent.

According to Zhang Man's judgment, the time of death of the deceased should have been 4 years ago.

After so long, the buttons still look new, which shows the quality of the buttons.

"Captain Liu, have you found the source of the button?"

Liu Qingshan Yaoyao said: "I asked several detectives to go to the market to ask, but they all said they had never seen such buttons."

If that's the case...

"Captain Liu, in this way, this button cannot appear in the grave for no reason."

"So, finding the source of this button is likely to be an important clue to solving the case."

"To compare it online, the quality of this button is very good and the composition of the gold edge is gold-plated."

"A single button is inlaid with gold edges, and its owner must be not an ordinary person."

"To compare on the Internet, especially on some foreign websites, some special clothing."

There is no such luxurious button culture in China.

On the contrary, in foreign countries, some nobles who have left their hands to the present pursue the inheritance of clothing, and have high requirements on clothing such as buttons, brooches, etc.

After all, buttons and suits are originally Western clothing and have only been introduced to China for nearly a hundred years.

"And, the knife used by the murderer is likely to be a ham slicer. Focus on checking some chefs' accessories to see if there are such button decorations."

In the previous case, there was a lot of information about this in the cognitive map of luxury jewelry obtained by Chen Yan.

"Okay, I'll make arrangements now."

The case investigation is underway.

The results of the comparison of the DNA information of the bones are still in progress.

The information database of missing people has been compared and no discoveries have been found.

Now, the detectives from Liu Qingshan are comparing the information in the DNA information database.

It is expected that the results will be produced in the afternoon.

However, Chen Yan did not have hope for this comparison.

After handling so many cases, I have never successfully compared them in this DNA information database.

Another is the analysis of organic matter in the cemetery.

This can determine whether the deceased enters the cemetery, whether it is a corpse or a skeleton.

This clue is clearly related to the clue of buttons.

If the deceased is a skeleton when entering the cemetery, the button may be left behind by the murderer.

Even the murderer is simply confusing the audience.

If the murderer enters the grave, he is a corpse and then rots and bones.

Then, the buttons in the deceased's mouth are likely to be clues deliberately left by the deceased.
