Because there is meteoric phosphotyrite in the soil there.

He may have meteoric phosphate stuck to the soles of his feet in his daily life.

Then when dancing in the pool of blood in the wooden house, the meteoric phosprite entered the blood?

Is that the truth?"

"You could say that, but..."

The forensic examiner was a little hesitant.

Shao Ming frowned: "But what?

Don’t hesitate, just say it.”

Shen Ting took over the conversation:

"What the appraisal room means is that the meteoric phosphotyrite is indeed very special.

But special cannot be directly equated with coming from criminals.

Now we can only say that the meteoric phosphotyrite came from the wooden house and the pool of blood.

But there is no definite answer as to how they got into the cabin and who brought them in.

It is certainly possible that it was brought into the cabin by the criminals.

But it could also be that someone was climbing a mountain, digging wild vegetables, or hunting rabbits, and after entering the forest, they were too tired and went to the wooden house to rest.

They may also have come from Hongye Bay, with meteoric phosphogypsum ore on their feet, left in the wooden house.

Afterwards, the criminals killed and skinned the people in the wooden house, and a large puddle of snow gathered on the ground.

Meteorite iron phosphate particles entered the pool of blood.

Sampling and identification happened to be identified.

This is not only true for meteoric phosphotyrite.

Beeswax and cinnabar, two special substances, may also have this possibility."

When Shao Ming heard Shen Ting's explanation, his expression immediately softened. He looked at him and smiled.

“Chen Ting, you make sense.

So, how do we investigate this case?

We can't just give up on the Red Leaf Bay clue!"

“It would be a pity to give up.

But if we say we should search directly in Hongye Bay..."

It’s also very difficult!

The probability of progress is relatively too low!

Because the only clue now is Red Leaf Bay.

We can indeed go to Hongye Bay to check, but what should we check?

The criminal's occupation, appearance, etc. are all uncertain.

You can't just investigate forcefully!

Shen Ting pondered and continued to review the appraisal report brought by the appraiser.

Three special substances, namely beeswax, cinnabar and meteoric phosphate, can be identified from the coagulated blood.

The level of the Xinyi District Physical Evidence Identification Room is undoubtedly very, very high.

but!

Shen Ting also discovered that these three special substances are all solid particles.

It is insoluble in water and naturally insoluble in blood.

At most they are suspended in a pool of blood!

The difficulty of identification is naturally very high, but not the highest.

The most difficult part is to separate and identify special substances dissolved in the blood.

Shen Ting was looking at the spectrum and energy spectrum, trying to judge from the waveform whether there was any other special substance mixed into the blood.

“The number of three types of solid particles is still too small.

The key is that there is no necessary connection between the three.

If we can find more special substances and analyze them together, we might be able to produce specificity."

In modern society, material life is highly rich and developed.

The transfer of a single substance is very common, so it is naturally difficult to obtain clues about the criminal through a single substance.

However, if multiple substances, especially multiple special substances, are put together, the probability of producing specificity will increase significantly.

Simply put, it's like Cinnabar in the disappearance case on a snowy night.

Cinnabar alone doesn't mean anything.

But when cinnabar is combined with black dog hair, yellow paper fibers, mugwort fibers, and various mysterious substances, it creates specificity.

It is natural to think of metaphysics from this.

What Shen Ting wants to do now is to find more special substances until these substances can be combined with each other to produce specificity.

With the help of forensic geology and palynology, the analysis method of the atlas, Shen Ting quickly frowned:

"It seems that there really are other special substances!"
