"This information, worth one million, almost stopped the Song family from thinking of calling the police.

It definitely wasn't Matsumoto's hair that was made, but the murderer used this method after killing someone to avoid any problems with the Song family.

In this case, the third question, why no one reported it to the police in the past 20 years, can also be explained.

Shen Ting pondered:

"The remaining questions in this case are only about the whereabouts of the one-third of the bodies and some minor details about the crime scene."

At this time, Zhuo Yan found Chen Ting and said with a smile:

"Team Leader Shen, I think this case is almost over.

Leave this to others, you can go back to the police station and rest!"

Shen Ting pondered the small doubts that had not yet been resolved and shook his head:

"Don't rush yet.

In this case, the murderer's motives, the process of committing the crime, etc. are still relatively vague.

I'm here, researching further."

Zhuo Yan was very surprised:

"Team Leader Shen, are you saying that this case might have more complications?"

"Chief Zhuo, don't worry.

Overall, there should be no changes in this case.

I just have nothing to do, so I'll study the details a little more."

Chen Ting ignored Zhuo Yan, who was still in shock, and paced around the house, focusing on the bloodstains inside.

However, he was not an expert in bloodstain identification and could not see any doubts.

He didn't even notice what Hannibal said about the unpleasant distribution of blood.

He was a little hesitant about whether to exchange for bloodstain pattern analysis.

"There are so many suspicious points involved in the case, all of which remain unclear. Closing the case under these circumstances would be too dangerous and might even damage our reputation!"

And that's not my style of investigating."

The previous case of the punisher ultimately left two doubts.

Moreover, one of them also had a body whose whereabouts were unknown.

Another question is why the punisher killed the restaurant owner.

The former is caused by factors outside the case.

The latter punisher also gave an explanation.

In the case of the criminal, these two doubts actually have little impact on the murderer's crime process, the identification of the murderer, etc.

Therefore, it does not affect the investigation and conclusion of the case.

But this time the Wanfoshan corpse hiding case is different.

The case happened too long ago, which resulted in many key details not being answered through conventional investigations.

Based on the murder weapon and the crime scene, the murderer was indeed Zhang Li.

It is not certain whether Yu Qingwei was involved.

If he was involved, it is not certain who between him and Zhang Li led the murder process.

Also, assuming that the murderers are Zhang Li and Yu Qingwei, why did they kill Matsumoto Ziqing?

There is no answer yet as to whether it is a simple emotional dispute, or there are economic factors involved, or both.

There are too many uncertainties in this case.

Shen Ting was a little worried about closing the case like this.

The other police officers at the scene thought about it carefully and almost understood Shen Ting’s concerns.

Xiong Beibei scratched his head:

"But everyone involved in the case is dead. There's no way to find answers to these doubts, right?"

Xu Xinyi also wondered:

"It would be better if we could find an explanation for these doubts.

But closing the case now is a helpless move!

I can't find any other basis for investigation at the moment, so this is the only way!"

Zhuo Yan, who was standing next to him, also fell into deep thought:

"We have roughly investigated Matsumoto Kosei's social circle in Heng City.

But it took too long and not much information was found.

After he returned to China in 2002, he never returned to the island country and his company was acquired.

Using the identity of his younger brother Song Zipeng, he is basically lying down.

No new business was registered in an attempt to make a comeback.

The money obtained from insurance fraud was not used for investment.

Basically, it all became gambling money and was spent online.

According to Zhang Li's parents, after Matsumoto Ziqing came to Heng City, she actually had very little contact with Zhang Li.

We may not see each other for a year.

I would probably only look for Zhang Li when I'm short of money.

Even if he has a grudge against others, they will usually kill him when he is alone.

It is impossible to run to Zhang Li's house and kill him openly. Afterwards, Zhang Li did not call the police but wanted to move away.

Combining this information, Zhang Li is probably the murderer, and there shouldn't be any doubt about that.

but......"

Zhuo Yan's brows furrowed tighter and tighter:

"The doubts Team Leader Shen mentioned are indeed problems.

If the case file is submitted to the procuratorate in this way, they may return it to us for further investigation because the case is not clear.

It would be better if all doubts could be explained clearly.

Team Leader Shen, do you have any ideas?

Is there any way?

All Shen Ting could think of now was the suspicious bloodstains raised by Hannibal before.

He looked at the places where the bloodstains were found, but the blue fluorescence had already disappeared.

The time that the luminol reagent emits blue fluorescence after coming into contact with blood is actually very short.

Usually, after discovering fluorescence, police officers will immediately use cameras to take high-definition photos for subsequent investigation.

If it doesn't work, you can spray luminol reagent a second time.

Because the iron ions in the bloodstains only act as a catalyst and will not be reacted, they will not affect the secondary identification.

Shen Ting found the fluorescent photos taken by the police and looked at them again.

"The bloodstains on the walls and floor had obviously been wiped clean.

However, there are still bloodstains in the cracks of the floor, corners and other places.

Perhaps, we can try bloodstain pattern analysis?"

Bloodstain morphology analysis integrates many disciplines such as biology and physics, and is a very important technology in criminal investigation.

Its research object is, of course, the bloodstains at the crime scene.

By testing the shape, size, distribution, etc. of bloodstains, the specific mechanism of bloodstain formation is analyzed.

A more powerful bloodstain morphology expert can not only determine the corresponding bleeding location, bleeding amount, murder weapon, etc. based on the bloodstains at the scene.

It can even confirm the number of perpetrators, their physical characteristics, the specific process of the murder, the movement trajectory of the victims, etc.

"Analysis of blood splatter patterns is a relevant area of ​​expertise.

It can answer many of the doubts surrounding this corpse burial case."

Shen Ting pondered for a moment, and without hesitation, he directly exchanged for bloodstain pattern analysis...
