There were no corpses, only bloodstains. There was almost nothing left at the scene…
Looking at Ye Zhiyao carefully investigating the crime scene, Zhang Yang frowned.
This was the first time he had come into contact with a 'cold case', so he was definitely confused.
Moreover, he had never even attended police school and knew nothing about criminal investigation.
But…Zhang Yang was not stupid.
He began to learn on the spot, his eyes staring at Ye Zhiyao, learning how to investigate the scene.
Every movement, expression, and action of the policewoman was imprinted in Zhang Yang's mind.
This was the benefit of having a photographic memory.
I'm stupid, but I can fly.
Understand the cheater?
Not long after…Zhang Yang retracted his gaze.
He had the confidence to be the eyes after his rebirth.
His eyes were comparable to an eagle's, and he wouldn't miss anything unusual.
However, he did not discover anything!
"Sis, there doesn't seem to be anything, right?”Zhang Yang was puzzled.
"No?"
Ye Zhiyao turned her head and glanced at Big Boy." Have you heard of Lockard's Law of Material Exchange?”
Is that thing delicious…Zhang Yang was confused.
"Locard's Law of Material Exchange, also known as Locard's Law, is a phenomenon discovered by a criminal scientist.”
Ye Zhiyao taught him on the spot." From the perspective of criminal science, this law refers to…as long as the criminal suspect carries out a criminal act. It would definitely affect the victim and their surroundings at the crime scene, directly or indirectly. They would leave behind traces, consciously or unconsciously!”
" So high and mighty…" Zhang Yang's expression was serious as he gave him the respect he wanted.
" Reading the dossier is to let the criminal investigators chew on the details that are hard to notice and find the breakthrough point through their own ability and intelligence.”
Ye Zhiyao continued," But the dossier is dead after all. It is easy or unconsciously for the person who is responsible for the dossier to be subjective. It is also easy to mislead the person who reads the dossier." Therefore, if he wanted to solve a case, he had to see the scene.”
"Only when you are there can you find clues from the fingerprints, footprints, weapons…all kinds of traces.”
"The smarter you are, the better you will be at setting up a trap. You will be better at disguising the perpetrator at the scene. However, it would definitely be left on all kinds of traces.”
"What do you mean?" Zhang Yang frowned. He didn't quite understand.
"Stupid, Rocca's Law."
Ye Zhiyao was slightly annoyed." Didn't I tell you that as long as someone committed a crime, there will definitely be traces left behind?" We can't find it because we haven't discovered it.”
"But…"
Zhang Yang was a little puzzled." Is Rocca's Law that amazing?”
"I'm not sure if he's divine or not."
Ye Zhiyao shook her head." But so far, this law has not been overturned!”
Hiss…Zhang Yang gasped.
So awesome?
If what Ye Zhiyao said was right, Rocca's Law was really that godly.
There would definitely be traces of the perpetrator at the scene?
Zhang Yang's strong desire to find traces made him quickly calm down.
As his eyes searched the cellar inch by inch, the logic in his brain became rigorous and clear.
His entire person had also entered an inexplicable state.
It was as if there was only him and the crime scene in the entire world!
Traces, clues, traces, clues... Zhang Yang's eyes did not blink as he began to re-examine the cellar.
He didn't know how much time had passed.
His eyes stopped on the pool of blood, and his gaze froze.
Zhang Yang recalled a deduction he had made earlier.
He suspected that the murderer had used a method similar to ancient torture to drain the blood of the victim.
If this deduction was true, it would lead to a problem.
When people killed chickens, they would find a container to collect the blood to prevent the chicken blood from spilling.
If the murderer used the method of killing a chicken to drain a person's blood.
Moreover, he did not use a container to catch it and allowed the blood to spill.
Then…how did he manage to leave no footprints?
Footprints?
There were no footprints on the ground, and the traces of blood congealing were still very 'perfect'.
What was so strange about that?
Have you ever thought about the state of the body when the police found it?
He had been skinned alive!
In other words, the murderer skinned the victim while bleeding him.
It was absolutely impossible that he had skinned her before letting her bleed.
Here came the problem.
During the skinning process, the murderer must be standing next to the victim, right?
So, he would step on the ground, right?
The victim's blood was also flowing to the ground, right?
If that was the case.
How could the murderer's footprints not be left on the bloodstains on the ground?
How could it be a pool of blood?
Also, according to the case file, the forensic doctor suspected that the victim had been skinned alive.
Was that really the case?
No, wrong…Zhang Yang shook his head.
Ye Zhiyao had just taught him that dossiers were sometimes not completely accurate.
The person who wrote the dossier was likely to be subjective and mislead others.
Now, Zhang Yang thought of another problem.
Since the dossier might not be accurate.
Was the forensic doctor's deduction always accurate?
Zhang Yang's breathing stopped.
Assuming that his eyes weren't wrong.
There was no problem with the police investigation.
Rocca's Law was also correct.
However, there were no traces at the scene.
That could only mean…
Suddenly, Zhang Yang asked with a strange expression.
"Sis, who confirmed that this is the first crime scene?”
