Yi Qing said: "Aren't we just hypothetical analysis now? Yes, the vice principal Qian Hui came and Li Hongwei who stole things was all accidental, maybe this Shi Mingkai was waiting for such an opportunity? After Shi Mingkai jumped out of the window and escaped, he returned to the scene of the crime to see what happened to Jiang Lina. It turned out that Jiang Lina was sexually assaulted, or she was in a coma but not dead, Shi Mingkai was thinking about how to get rid of Jiang Lina, and simply killed Jiang Lina. Do you think this kind of analysis is reasonable and logical? Does it also explain Li Hongwei's confession?"

"That being said, Captain Yi, you have also analyzed it thoroughly. It's just that all of this is based on assumptions and inferences, and we don't have any substantial evidence to support this inference now, let alone convict Shi Mingkai. Wang Tao said with some regret.

"Yes, this is also what I am considering, how can I prove all this again?" Yi Qing frowned, lost in thought.

After a long time, Yi Qing raised his head and said, "I still have to report this new situation to the old director, and see what good ideas the old director has." ”

After speaking, Yi Qing picked up the file and went straight to the old director's office.

After listening to Yi Qing's detailed report, the old director paused for a while and said: "This case has been done here, it can be said that it has reached a critical time, whether Shi Mingkai is the real murderer, or Li Hongwei's nonsense must be investigated." Now our only breakthrough is to put it on Shi Mingkai. I saw the time to make head-on contact with Shi Mingkai, and if we had reasonable suspicion, we could ask him about him and see what he had to say. ”

Yi Qing nodded and said, "I will immediately arrange a surprise trial of Shi Mingkai." ”

The old director continued: "I remind you that this sudden trial must emphasize suddenness, because it is difficult for people to immediately establish a psychological defense line in an emergency, and it is also the easiest to break through. If it doesn't work out this time, it's not going to be easy. So, it's better to be a first-time success. You go and prepare. ”

Yi Qing saluted the old director and said, "Guarantee to complete the task." ”

Back in the office, Yi Qing began to keep accounts, thinking about how to contact Shi Mingkai head-on, and the next interrogation plan.

Yi Qing finally decided to set the interrogation time in the early hours of the morning. From 1 to 3 o'clock in the evening, it is the time when a person wants to sleep the most, and it is also the time when the mental state is the most unfocused.

Yi Qing set the time at this time, and he also wanted to take Shi Mingkai in one fell swoop.

At twelve o'clock in the evening, Shi Mingkai, who was sleeping in a daze, was "invited" to the interrogation room of the serious crime team by the investigators of the serious crime team of the Public Security Bureau.

Until he sat on the chair in the interrogation room, Shi Mingkai didn't understand what was going on.

Sitting at the interrogation table was a row of scouts dressed in neat police uniforms.

In order to create an atmosphere and give Shi Mingkai enough psychological pressure, Yi Qing asked the investigators of the serious crime team to fill all four seats in front of the interrogation table, and first of all, he had to suppress Shi Mingkai in momentum.

Sure enough, Shi Mingkai looked at a row of policemen sitting in front of him with serious expressions, and then looked at two policemen standing straight next to him, he felt that the atmosphere was very heavy, and there was a very heavy sense of depression, which made people a little breathless, Shi Mingkai couldn't help but lower his head and think nervously.

"Shi Mingkai, look up, do you still know me?" Yi Qing asked first.

Shi Mingkai looked up at Yi Qing and said cautiously: "Of course I know, you are Captain Yi of the serious crime team, I really have to thank you for the incident last time, and clear up my grievances." ”

"It's good to know me, then you also know what kind of place this is, so I don't need to introduce it. Since it's an acquaintance, I won't talk nonsense, just open the skylight and say something, do you know why I invited you here today?"

Shi Mingkai shook his head a little dazedly.

"Shi Mingkai, do you think Jiang Lina's case is over?" Yi Qing asked.

"Yes, haven't you already caught the real murderer? It's Nana who killed me by that thief......" Shi Mingkai said and suddenly became emotional, and couldn't help crying.

Yi Qing waited for Shi Mingkai to cry for a while, and then asked, "Shi Mingkai, don't cry, if you want to cry, let's cry later." I'm telling you, you can't be fake, you can't be fake. People are doing it, the sky is watching, if a person does evil, sooner or later he will be punished, don't you say?"

Shi Mingkai wiped the tears from his eyes and said, "Captain Yi, to be honest, I was sleeping in the middle of the night, I really don't know what you called me here for, can you tell me clearly, what did I do wrong?"

Looking at Shi Mingkai's tough attitude, Yi Qing asked from a different angle: "Then let me ask you, what is the relationship between Shi Mingkai and Jiang Lina?"

Shi Mingkai replied: "We started a teacher-student relationship, and later you also know that we are secretly in love, that is, a love relationship, and the relationship is very good, Nana gave me everything, we are already ready to get married, who would have thought that such a thing would happen." My Nana is miserable!"

Yi Qing snorted and said, "Since you said that your relationship with Jiang Lina is so good, what is the relationship between you and Zhang Xianglan?"

Hearing Zhang Xianglan's name, Shi Mingkai's expression froze significantly. Obviously, Shi Mingkai was very surprised and a little flustered by Yi Qing's sudden mention of Zhang Xianglan's arrival.

"You also know Zhang Xianglan, that was the person who was introduced to me later, and now we are still in contact, and there is nothing else. Shi Mingkai lowered his head and said.

"Shi Mingkai, since I mentioned Zhang Xianglan, you should understand what I mean by this. As far as I know, you didn't know Zhang Xianglan after the crime, but a year ago, that is, at this time last year, you met Zhang Xianglan, and your relationship has gone beyond the relationship of ordinary friends, and at that time it was a few months before the crime, can you tell me why?" Yi Qing's eyes were fixed on Shi Mingkai, and he had a feeling that he wanted to eat Shi Mingkai in one bite.

Shi Mingkai obviously saw that he was a little flustered, and his hands nervously grasped the armrests of the chair, rubbing back and forth. Yi Qing understood that this was a manifestation of a weak heart, a kind of lie that was seen through and wanted to escape.

After hesitating for a while, Shi Mingkai raised his head and said slowly: "Captain Yi, I did hide the situation. Actually, I'm just a villain who forgets his righteousness. When I first met Nana, I fell in love with her beautiful faces, and I was fascinated by her every day. ”
