"Shall we wait a little longer or go in and interrogate now?"

Lao Zhang glanced at Tang Zhibin, who was sitting in the interrogation room, from the surveillance and asked me.

"Wait a little longer, when the rest of the people have all returned from Du Wei's house, let's start the interrogation again."

Lao Zhang nodded, didn't say anything, turned around and walked out of the monitoring room to prepare things.

I carefully observed Tang Zhibin through the surveillance, thinking in my heart how to interrogate this person for a while.

From all the previous behaviors, it can be seen that this person is not as easy to deal with as we think.

From the time he was arrested to the present, Tang Zhibin has always been very calm, and his psychological quality is so good, it is estimated that it will not be easy to be tried for a while.

Thinking about this, I have a slight headache.

"It's okay to start, let's go in and interrogate."

At this time, Lao Zhang suddenly walked in and told me that the rest of the people had all come back from Du Wei's house, and now they were downstairs to rectify, I nodded after hearing it, and followed Lao Zhang out of the monitoring room and into the interrogation room.

As soon as he sat down, Tang Zhibin took the initiative to talk to us.

"What do you want to know?"

Lao Zhang and I glanced at each other, and we didn't say anything in tacit understanding.

"Looking at the posture of the two of you, you should want me to take the initiative to explain?" Tang Zhibin saw that neither of us spoke, and he was not in a hurry, he slowly leaned back on the chair behind him, and found a slightly more comfortable position for himself to sit.

"It's a pity that you caught the wrong person, I'm not the person you need to arrest at all, it's useless for you to arrest me, and besides, I don't know anything. I'm just an ordinary university teacher, and my main activity every day is work, and other than that, it's a little hobby......"

"Then why did you appear in Du Wei's house?"

"Why, only you can know Du Wei and go to his house as a guest, can't I? Besides, you have prepared a search warrant for such a big battle? If you don't have a search warrant, you're doing something illegal......"

Tang Zhibin's current performance all confirmed my thoughts at the time, and this interrogation will definitely not be so smooth sailing......

"You don't have to worry about the search warrant or anything, it's your own that you should worry about the most now. We have already obtained Li Xiao's diary, and in his diary you have recorded in detail how you committed the crime, so you should not do some useless struggles. ”

Lao Zhang looked at Tang Zhibin and didn't cry when he saw the coffin, and directly took out the evidence, hoping to use this to break Tang Zhibin's psychological defense.

But what disappointed him was that Tang Zhibin was not only not defeated, but also asked about the diary.

He asked us in detail where we got this diary, whether we had conducted a professional handwriting examination, and whether we had confirmed whether the contents of the written record on it were true......

"Tang Zhibin, I can tell you very clearly now, the reason why this diary can be used as evidence by us has already shown that this diary has undergone the most professional appraisal, you really don't have to worry too much about such things, we can end the diary matter first, and then I want to ask you a few questions, and I hope you can answer truthfully."

I watched the rhythm become more and more deviated by Tang Zhibin, so I quickly took over the words and carried out the interrogation work later.

"Tang Zhibin, during your tenure, did you come into contact with a person named Li Xiao? Also, have you come into contact with a person named Shang-Chi? What is your relationship with each of these two people? ”

Tang Zhibin was obviously stunned for a moment after hearing the names of Li Xiao and Shang Zhi, and then asked me who these two people were.

Lao Zhang was about to speak when I stopped him: "Okay, then I'll continue." ”

I flipped through the information that Lao Zhang had prepared for me, and continued to ask.

"Can you tell us a little bit about what your usual research work focuses on? And what is the content of your usual teaching work? ”

Tang Zhibin thought about it for a while and began to talk to us.

The things he talked about are basically the same as those given in the materials, and he never mentions the illegal experiments mentioned in Li Xiao's diary.

As far as the evidence we have so far is concerned, it is not enough to directly convict Tang Zhibin, but he can only not rule out his suspicion of crime.

And Tang Zhibin will not directly tell us everything he has done, which directly puts our kidney deficiency work into a deadlock.

I couldn't ask anything, so I walked out with Lao Zhang.

"What are we going to do next?"

This diary is too easy to overturn the case, although these things can be used as evidence, the above will never let us close the case so hastily, even if the top is willing to close the case like this, I and Lao Zhang will not be happy from the conscience.

There is only one step between a genius and a madman, Tang Zhibin has used all his knowledge for good things, which will inevitably benefit one party, but now he has begun to study lethal viruses in order to become famous.

We have only investigated the victims Shang Zhi and Li Xiao now, Tang Zhibin has been engaged in such research for more than a day or two, how can we be sure that except for Shang Zhi and Li Xiao, there is no one else who is a victim, or will become the next victim?

"Apply for a search warrant, search his lab and his residence, there's not much chance you'll find anything, but that's all you can do."

I put away all the information in my hand and began to discuss it with Lao Zhang.

"I'll take care of the matter of applying for a search warrant, you can take advantage of this time to go to Li Xiao's place again!" Or look at Li Xiao's diary again, Tang Zhibin can't be so blatantly put so many things in the school's laboratory, he will definitely have a secret laboratory somewhere else. ”

I nodded, and did as he said.

I hurriedly went back to my office, took out all of Li Xiao's diaries, and read them carefully.

After searching for a long time, I couldn't find a few useful messages, which made me very irritable.

"Captain, go over and answer the phone...... It's a call from above, asking for an order to be given to you in person, and you have to answer it in person......"
