Soon, he locked onto a technique called "trace evidence."
Just as the name suggests!
This technique is to use the most advanced equipment to study physical evidence that is extremely subtle in quantity and quality.
For example, fluff, powder invisible to the naked eye, fungal spores on fibers, etc.
There is no limit to the type of physical evidence, but it must be very small in size.
As in this case, the special substance mixed into the pool of blood is difficult to detect, difficult to separate, and even more difficult to identify its type.
This is the subject of trace evidence research.
Shen Ting briefly read the introduction of the trace evidence and quickly confirmed—
It is indeed very difficult to separate and identify specific substances from a pool of blood from all over a person's body.
The identification of trace evidence is inherently difficult.
Now, the physical evidence is mixed with blood, and the difficulty of identification has increased by more than one level.
Among all trace evidence, it is also the most difficult type.
"If the special substance from the criminal's shoe soles was a solid crystal that was difficult to dissolve, it would be easy to deal with.
Separation and identification are relatively easy.
But if the special substance in Muwu's blood dissolves into the blood, it will be troublesome.
The difficulty of separation and identification will increase exponentially again.”
However, no matter what the situation is, there is a solution in the identification technique of trace evidence.
If the physical evidence identification room cannot identify the special substance in the pool of blood, then Shen Ting can help.
“Speaking of which!
The technical team found very few clues inside and outside the cabin."
The clues found in the DNA laboratory, the forensic office, and the physical evidence identification room were almost negligible.
Only the identification results from the Trace Examination Office are interesting.
"In particular, according to the trace examination, the blood spots on the cabin wall were most likely caused by the leatherworker dancing around the headless corpse."
At that time, all the police officers in the conference room found the scene very terrifying.
But Shen Ting thought it was very normal.
The only profile he had of the leatherworker was that he was in a state of extreme excitement, even madness.
Dancing around a headless corpse is quite fitting for this situation.
“However, the problem remains the same.
What is it that drives the leatherworkers into this frenzy?"

Tomorrow is the Spring Festival!
From time to time, the streets were filled with the sounds of children's laughter and the explosions of firecrackers and fireworks.
Chen Ting thought of his sister, Chen Manman. She was probably clamoring for her father to accompany her to set off fireworks!
If Shen Ting was at home, she would just yell at Shen Ting.
"These little kids are so happy because it's Chinese New Year and they can receive lucky money, wear new clothes and set off firecrackers.
The murderer was setting off fireworks and dancing. What was causing him to go so crazy?
