To tell the truth, this Tang Zhibin is too cunning, even if he is locked up in interrogation by us, he is still a dead duck with a hard mouth, and refuses to reveal half of the true situation to us.

Although I vaguely feel in my heart that Tang Zhibin is lying to us, as a criminal policeman, I must also come up with evidence to prove that he is lying.

Finally, when everything was at a loss, Lao Zhang suddenly leaned over to my ear and said softly to me.

"I said, why don't we use a polygraph quickly?"

Hearing Lao Zhang say this, I frowned, although there is no one in this lie detector criminal investigation team, but as long as this Tang Zhibin is brought into the team, you can try this lie detector.

So I lowered my head and said to Lao Zhang.

"Then let's try this method, tomorrow I will apply to the team to bring Tang Zhibin back, and then we will use a lie detector to see if what he said is true or false, if it is false, then this case is estimated to be over."

In fact, this case dragged on for too long, and for the members of our criminal investigation team, the longer the case dragged on, the more unfavorable it would be for us to conduct an in-depth investigation.

Although Tang Zhibin told us that he was a university teacher and would not do such a thing, I always felt that the eyes in his eyes when he looked at me were calm and a little ruthless, as if things were not as simple as he described.

Although I am very puzzled in my heart, I don't have full evidence, so I can't keep him in the police station for too long, otherwise, Tang Zhibin has every good reason to sue me, then I'm afraid I can't be justified and can't say it at that time.

I just sighed leisurely, and then said to Tang Zhibin.

"Since you're so sure you're telling the truth, I'm going to ask you to come to my house tonight and spend the night together."

In fact, I really can't help it, because if Tang Zhibin is not a murderer, it's okay, and I can be regarded as a friend, but if Tang Zhibin is really a murderer, I'm afraid that this night can also let him smuggle to a far place, and it will not be easy to arrest him again when the time comes.

After Tang Zhibin listened to my words, he just smiled contemptuously.

"I said, is this how you put the common people under house arrest? I didn't do anything wrong, so why should I be with you? Do I know you well? I'm a bit withdrawn by nature, I'm not used to staying at other people's houses at night, and I still have a bit of a cleanliness habit, I'm afraid your house is not suitable for me to live in. ”

Hearing that Tang Zhibin rejected my request so resolutely and decisively, I was even more sure that even if he was not the murderer, he was related to this case, so I lowered my brows and said to Lao Zhang.

"No matter what method is used now, we have to monitor Tang Zhibin, but we can't let him escape."

But Lao Zhang's brain was indeed a little dull, he didn't react when he heard me say this, just stared at me blankly, and after a few seconds, he asked in a low voice.

"Why should we monitor him, besides, the police can't detain people for more than 24 hours, we have now seriously violated the law, if Tang Zhibin goes out and wants to sue us, it is very easy and easy, this is just a case, and we are not sure whether Tang Zhibin is the murderer or not, so getting into trouble is probably not very reasonable."

When I heard Lao Zhang say this, I immediately held my forehead.

"When do I let you use the police to spy on him, I'll let you spy on him yourself."

Lao Zhang suddenly realized when he heard me say this, and then said to me with confidence.

"I see, boss, I'll go down right away."

Hearing that Lao Zhang was full of confidence, I was relieved for a while, and then pretended to be the owner of the ship, and said indifferently to Tang Zhibin.

"Mr. Tang, now that we have asked all the questions, after listening to your answers, we feel that you really have nothing to do with this case, so now you have been officially released."

But Tang Zhibin did not leave the interrogation room after listening to my words, and still sat on the stool, stilting his legs.

To be honest, when I saw Tang Zhibin's appearance, I didn't think he looked like a university teacher at all, he looked like a ruffian, and he was a scheming ruffian hooligan.

Although I was a little dissatisfied in my heart, I still stared at him quietly on the surface, and Tang Zhibin didn't answer me, and the two of us just looked at each other.

In the end, I couldn't help it, and then I said to Tang Zhibin.

"I said Mr. Tang, you have been released now."

When Tang Zhibin heard me say this, he immediately sneered.

"I said Mr. Policeman, do you know that you have been approaching me for more than 24 hours, and now I am released, but I am very dissatisfied, so I hope that your superiors will come and explain all this to me, otherwise, I am afraid that you will be unlucky."

Actually, to be honest, I did detain him for more than 24 hours, but it was only a few minutes, so why did he care so much.

I don't think Tang Zhibin looks like the kind of person who cares, plus he is a university teacher, he must have a certain literary accomplishment, and he will not be like scolding women on the street, he must be justified in doing this.

Although I was very puzzled in my heart, since Tang Zhibin made such a request, I also had to meet him, but once I asked my superiors to come over, I was afraid that I would lose my job, so I persuaded Tang Zhibin with kind words.

"I said Mr. Tang, in fact, I wanted to let you go for a long time, but your answer is a little ambiguous, we police also need time to think, plus this case has indeed dragged on for a long time, the police can't let go of any clues, so I hope you can understand a little."

After Tang Zhibin listened to my words, he immediately put down Erlang's legs, and then said to me.

"It turns out that you didn't listen to what I just said, I said it, I'm not a murderer."

I have never seen Tang Zhibin like this, and even though he had faced our endless interrogation in the interrogation room before, he was not so serious.

I don't know what he wants to do, but after all, we are at fault in this matter, so I can only say to Tang Zhibin.

"Mr. Tang is really embarrassed, our police are indeed a little negligent, so I hope you can bear more."

Tang Zhibin, after listening to my words, suddenly pressed his hand on the table and stood up suddenly, which frightened me as a criminal policeman.

"I told you, I hope your superiors can come over!"
