In fact, most people didn't know that traces of blood could be left for a long time. Even if the blade was hit by water, it could still be detected by special means of blood composition DNA testing within three to five years.
Because the blood factor still existed, but the human eye could not see it.
Therefore, Su Dong did not lie to him.
In addition, Su Dong also told Li Jiu that Liu Fuqun was a criminal and that he would definitely be lenient if he confessed. It did not take long for Li Jiu to admit it.
Of course, Su Dong had already known that Li Jiu was the murderer, so it was naturally much easier for him to do the reverse deduction.
However, it was indeed extremely shocking for Officer Yang and the other two.
It was like a final exam, where you didn't even have a clue about the first multiple-choice question, but someone else had already finished it and scored full marks.
"You actually know about the blood test?" A strange look flashed across Officer Yang's eyes.
Su Dong smiled." I know a little.”
Officer Yang nodded." There's one more question.”
He stared at Su Dong." How did you know that Li Jiu was the murderer?”
"I guessed."
Officer Yang was stunned." Guessed?"
"That's right." Su Dong shrugged." Holmes said that after committing a crime, the murderer will often return to the crime scene.”
"Look, the weather is so hot now, and this is the suburbs. Most of the people around are fishing guys and uncles and aunties who do farm work and make breakfast nearby. It's very strange that such a young man suddenly came.”
"And what's even stranger is that he turned around and ran the moment he saw me. Isn't this a proper escape from punishment?!”
Officer Yang and the other two were speechless.
What he said made sense…so…f * cking ridiculous!
How could this person say something so nonsensical, and even though he thought about it carefully, it still made sense?
Officer Yang pondered for a moment and asked,
"How did you know that Li Jiu was carrying a knife?”
Su Dong grinned and spread his hands." I don't know. He fell out by himself."”
Was that so?
What a coincidence!
Officer Yang looked at him deeply and asked the last question,"
"One last question."
He looked at Su Dong in surprise." Who is Holmes?”
“………”
This time, it was Su Dong's turn to be silent.
After a while, he said in surprise,
"You're a police officer, don't you know Sherlock Holmes?!”
Holmes!
This was the first famous detective in history!!!
A world-famous figure!
As a police officer, how could you not know?!
Looking at Su Dong's expression, Officer Yang was also at a loss.
Who was Holmes?
Was it important?
Why should I know him?
However, Su Dong's expression was too confident, causing him to lose a little confidence.
Hence, Officer Yang turned around and looked at the two policemen.
"Have you heard of Sherlock Holmes?”
The two policemen shook their heads in confusion.
Su Dong fell silent again.
He suddenly realized a problem.
He had been fishing since he transmigrated yesterday and had never truly understood this world.
Could it be that this parallel world was different from Earth?
With this mentality, Su Dong asked tentatively,
"Then do you know Kudo Shinichi?”
Officer Yang shook his head.
"Where's Detective Poirot?"
"Where's Lu Xiaofeng?"
"Where's Jin Tianyi?"
"You've heard of Haruka Kasugano, right?"”
“………”
In the end, Su Dong left in a daze.
He found a shady spot nearby and began to explore this unusual world for the first time with the borrowed phone.
Seeing that the matter seemed to be over, the photographer immediately walked to the shade and sat down.
The content just now could not be broadcasted, but he had to live stream the river water for half an hour under the scorching sun.
Now, he could finally rest.
On the other hand, Officer Yang shook his head and ignored Su Dong.
The questions that the two police officers had interrogated were not detailed enough. He needed to interrogate them again to make up for the gaps.
"Li Jiu?"
"Yes."
"Tell me how you killed Liu Fuqun again.”
"Oh, that day was Sunday…"
"Is this your first time meeting Liu Fuqun?"
"Yes."
"We didn't find Liu Fuqun's wallet and identity documents when we identified the body. Do you know where they are?”
"I threw it into the river with the corpse. It shouldn't be far from where the corpse was fished up.”
Ten minutes later, Officer Yang nodded. To put it simply, Liu Fuqun had run out of money one night and happened to see Li Jiu, so he " borrowed " some money from him. Li Jiu refused to give it, so the two of them quarreled. In his excitement, Li Jiu took out a knife and stabbed Liu Fuqun.
It was a very cliché and ordinary plot that would be criticized by readers even if it was written in a novel, but it was indeed something that happened in reality.
She took out a pen and handed him the testimony.
"Read it once. If there are no problems, sign and press your fingerprint.”
After a cursory look, Li Jiu signed his name. He had no intention of running away and denying it. He only wanted to cooperate with his work and get out of prison as soon as possible.
Officer Yang put away the testimony and handcuffed Li Jiu. Suddenly, he thought of something and asked,
"By the way, do you know Sherlock Holmes?”
Li Jiu: "??"
