Through the lie detector, he had found the real culprit of the Slaughter Case. Not only was Zhao Yu shocked, but he also let out a sigh of relief.
Since Liu Pengfei and Lin Meifeng were not having an affair, that meant that Lin Meifeng had nothing to do with Yu Zhigen's death!
Before this, Zhao Yu had felt that he was powerless in this case. Even though his instincts told him that Lin Meifeng might have something to do with the Slaughter Case, he did not want to see Lin Meifeng as the real culprit!
This poor woman had suffered too much. Now that she was finally living a happy life, why did she have to destroy everything she had so cruelly?
But to be one hundred percent sure, Zhao Yu asked Liu Pengfei, "When you killed Yu Zhigen, were you hired or instructed by Lin Meifeng?"
"No! I … "
Liu Pengfei wanted to say something else, but Zhao Yu was worried that he would say too much and cause the lie detector to fail, so he quickly covered his mouth.
In the end, the light turned green, and Zhao Yu finally felt relieved. It seemed that Yu Zhigen's death had nothing to do with Lin Meifeng!
But … at that moment, Zhao Yu had a flash of doubt. He still felt that something was not right!
If Liu Pengfei really had nothing to do with Lin Meifeng, then why would Lin Meifeng's photo appear in Liu Pengfei's wallet?
Could it be … Li Beini's guess was correct?
Liu Pengfei really had a crush on Lin Meifeng!?
Thinking about this, Zhao Yu wanted to ask a few more questions, but five minutes had passed, and the lie detector had ended. The device bar showed that the number of lie detectors had decreased by one, leaving four!
Tsk tsk …
These five lie detectors had been obtained by Zhao Yu after he had solved the Lost Hand Case. The completion rate was more than ninety percent. At the time, Zhao Yu had looked down on this thing, but now it seemed that this lie detector was too powerful!
With this thing, no matter how stubborn the criminal was, they would have nowhere to hide and be exposed!
At that moment, Liu Pengfei was sweating profusely, his mind exhausted. His chest was heaving up and down, as if he was under a lot of pressure.
Miao Ying was smart. Even though she did not have a lie detector, from what she had just seen, she had already guessed something!
"Oh... no wonder Zhao Yu was so determined to interrogate Liu Pengfei! It turned out that Liu Pengfei was involved in another case! Moreover, it was a murder case!
Thinking about this, Miao Ying's prejudice against Zhao Yu lessened. She quickly arranged for her subordinates to investigate the Uptown Slaughter Case and send people to investigate Zhao Yu's background!
What surprised Miao Ying was that Zhao Yu, who had been interrogating Liu Pengfei, suddenly stopped talking. He took out a pen and started writing on his file, completely ignoring her and Liu Pengfei's existence.
But … Zhao Yu's silence made Liu Pengfei feel even more guilty. He was sweating profusely, his expression stiff and nervous. He felt like he was sitting on pins and needles, twisting and turning in the interrogation chair.
He wanted to explain to Zhao Yu that he had nothing to do with Yu Zhigen, but when he opened his mouth, he couldn't make a sound. This was because he was worried that his explanation would attract even more suspicion …
However, after a few minutes of silence, Zhao Yu still did not say a word. He was still seriously writing something in his notebook.
Miao Ying could not help but look at him curiously, but Zhao Yu purposely covered his eyes, not letting her see.
But, actually, but …
Zhao Yu had only drawn a lot of little jerks on the paper!
The reason why Zhao Yu had stopped talking was not because of psychological warfare, but because he had used up his Invisible Lie Detector and did not know how to continue the interrogation!
He clearly knew that even though he had confirmed that Liu Pengfei was Yu Zhigen's murderer, there was no evidence left in the Slaughter Case. There were no fingerprints, footprints, blood stains, DNA, etc. Without evidence, he could not make Liu Pengfei admit his guilt!
The current situation was not good for Zhao Yu either. Miao Ying was watching from the side. He could not touch even a finger of Liu Pengfei's!
But … he had finally gotten the opportunity to interrogate Liu Pengfei, and he had finally found the murderer of the Slaughter Case. He was not willing to give up just like that.
What should he do?
Other than using force, was there any other way to make Liu Pengfei admit his guilt?
Without concrete evidence, even if he was interrogated for three days and three nights, he would not confess! But … where was the evidence? There really was none!
With no other choice, Zhao Yu could only draw little jerks on the file, thinking hard as he drew.
Suddenly, there was a knock on the door outside the interrogation room. An investigator walked in and handed Miao Ying a few files. Miao Ying had wanted to leave the interrogation room, but she was worried that Zhao Yu would go too far, so she took the files and found a corner far away from Zhao Yu to flip through them.
As the metal door closed, the atmosphere in the interrogation room became tense. Zhao Yu continued to draw little jerks on the file, while Miao Ying read the files seriously. The two devils did not care about Liu Pengfei, who was in the interrogation chair. This made Liu Pengfei feel even more uncomfortable, as if there was a dagger on his back.
Liu Pengfei knew one thing: before the storm, there was always an unexpected calm! A dog that bites doesn't bark! He was not sure what would happen to him later.
Time ticked by, and after a quarter of an hour, Miao Ying finally finished reading the file.
Oh …
She finally knew the ins and outs of Zhao Yu.
Interesting. This guy had solved two big cases, and even caught the culprit himself. He had received a city-level commendation, but now he was sent to the Cold Case Unit. It seemed that this guy's temper was really stubborn!
But judging from his violent actions in the Ruyang Key Case Investigation Unit, this guy was also very persistent! If it were someone else, no one would put themselves in such a dangerous situation for a simple case investigation!
This guy …
Suddenly, Miao Ying's hostility towards Zhao Yu lessened a little. After reading the information about the murder in the uptown area, her eyes lit up, as if she had found something important.
At that moment, Zhao Yu seemed to have thought of something and stopped drawing. He pouted his lips at Miao Ying, signaling her to go out and talk to him.
Miao Ying nodded in agreement. After the two of them left the interrogation room, Zhao Yu looked at Miao Ying and said, "Captain Miao, can we discuss something? Can I … borrow something from you? "
"Hehe …" Miao Ying laughed, and her eyes shone with a sly light. It was as if she could guess what Zhao Yu was thinking. She asked, "Why? Do you want me to be in cahoots with you? "
"Huh?"
Zhao Yu was shocked, and thought to himself, "Oh no! This female devil is so smart? It's over, the trick that I thought of was exposed with one sentence. It's over, it's over, it's over!
