Just when Yi Qing felt that he had suppressed Qian Huilai with his majestic momentum, and was about to inquire further, he saw Qian Huilai in front of him shaking all over, and with Yi Qing's intimidation, he saw Qian Huilai fall to the ground on his knees, raise his hands and say: "Comrade policeman, I confess, I confess!"

Qian Huilai's performance was a bit unexpected by Yi Qing, he didn't expect to break through the psychological defense line of Qian Huilai so quickly.

However, having endured the test of the police profession for many years, Yi Qing has developed the ability to be indistinguishable from mood and mood, although he is a little surprised in his heart, he still looks very calm and normal on the surface, just like Qian Huilai's performance has long been expected by him.

Yi Qing said in a very calm tone: "Okay, get up, you have to trust the government, as long as you truthfully explain the problem, you will be treated leniently." ”

Qian Huilai nodded, stood up, and sat back on the interrogation chair.

Yi Qing handed Qian Huilai a cigarette, and Qian Huilai shook his head, indicating that he would not smoke. Yi Qing took back the cigarette he handed over, put it in his mouth, lit it and puffed out a puff of cigarette and said, "How about it, you can start." ”

Qian Huilai nodded and said, "Actually, I'm too small, and I love to take advantage of small things." When I used to be the head of the General Affairs Section, I used to take some things from school home and use them. Like alcohol and the like, take it home to cook and boil water, clean and fast. ”

Yi Qing laughed contemptuously and said, "You really know how to live." ”

Qian Huilai wiped the sweat from his face and said, "Let the police officer smile." In fact, it's all my wife's fault at home, she loves to take advantage too much. Later, I became the vice principal, and although I was promoted, it was not so convenient to get those things again. I knew that there was alcohol in the school's laboratory building, so I secretly kept a key to the laboratory building, and sometimes went to the laboratory building to get alcohol on weekends when no one was around. ”

"Where's your key?" Yi Qing asked.

"After the incident, I was very scared and wanted to throw away the key, but I was afraid that if the public security bureau found out, I wouldn't be able to take it out, so I hid it in an empty flower pot in my yard. ”

Yi Qing's eyes glanced at a colleague beside him, and that colleague would go out unwillingly.

Yi Qing motioned for Qian Hui to come: "You go on." ”

"On that day, the day of the crime, about 8 o'clock in the evening, I went to get alcohol in the laboratory building, which was in a room on the second floor. As a result, I entered the room to find that the windows were not closed properly and the curtains were not drawn tightly. I think maybe the lab teacher forgot, and I went up to close the window and close the curtains. Then, I grabbed the alcohol and left. ”

"What else?" asked Yi Qing.

"Also, when I was holding alcohol, I accidentally got my hand cut by something sharp on the lab bench, maybe a piece of broken glass, etc., and I also took a piece of gauze from the laboratory and wiped the blood. Nothing else. "Money will speak.

"That's all?" Yi Qing felt that the money would come, and he was really good at acting.

"Then, the next day, I heard that there had been a murder in the lab building, that a female student had been killed, and that it was the same lab I had been in that night. Officer, I'm telling you the truth, when I went into the lab, there was no one inside, and if there was one, I wouldn't be able to see it. "The money will come, and beads of sweat will appear on the forehead.

"What did you say, when you went to the laboratory building, there was no one inside?" Yi Qing asked again.

"Yes, there's really no one in there. I swear!" the money would reply.

"Swear, if the oath works, what else do you want us police to do, don't talk about these useless things, to be honest!" Yi Qing was a little impatient, for this guy in front of him, who was a little nonsense, it had come to this point, and he was still quibbling, he really didn't want to die in the heart of the Yellow River.

"Officer, I'm telling the truth. "The money will come, but I still insist that I haven't seen anyone.

Yi Qing shook his head, this guy is really difficult.

Yi Qing put away the record book and decided not to talk nonsense with him anymore.

Out of the interrogation room, Yi Qing arranged for his subordinates to say: "Notify the forensic doctor and trace inspection technology to come over, and give money to do a comparison of blood type, footprints, and fingerprints." ”

After that, he was about to go back to the office. At this time, a colleague came back from outside and handed Yi Qing a key with a red rope attached: "Captain Yi, this is the key that is placed in the empty flower pot."

"Have you tried it?"

"I tried it, and it was the key on the door of the laboratory building. ”

"Well, I don't believe that I can't kill you. Yi Qing gritted his teeth a little in his mouth.

The next day, Xiao Wei and Wang Tao came to the school to see that everything was normal, including Lao Li Tou.

It seems that Liu Zhengyi's secrecy measures have been done well, and the teachers and students at the school have not received the slightest rumor.

Xiao Wei and Wang Tao met with Old Man Li first, and quietly told him the news that Qian Huilai was arrested, Lao Li Tou was a little surprised, he didn't expect the Public Security Bureau to act so quickly, and he actually arrested Qian Huilai overnight.

Lao Li Tou was very glad that he was able to get out, and at the same time, he was also full of gratitude to the two young students in front of him.

After Wang Tao instructed Lao Li Tou to keep the news of Qian Hui's arrival secret, he met with Situ Chunyan with Xiao Wei.

Qian Huilai has been caught, so his undercover mission will be completed, and it will only take five or six days before and after. I came to meet with Situ Chunyan in order to properly arrange my retreat. Since it came quietly, it is enough to leave quietly. said to the outside world that Wang Tao had found a relationship and had been specially recruited by the police academy in the province.

In the past few days, Xiao Wei has a very good impression of Wang Tao, smart, wise, and has a very fast brain and strong adaptability, which Xiao Wei admires in his heart.

Wang Tao also has a good impression of Xiao Wei, he is a good seedling to be a policeman. In particular, he is very convinced of Xiao Wei's meticulous and keen observation and judgment, and he loves to learn, of course, only for a certain aspect.

Situ Chunyan and Xiao Wei sent Wang Tao away, and when they returned, Xiao Wei also went to the gate to see Lao Li Tou, and later naturally became a frequent visitor to Lao Li Tou.

The school's side handled it smoothly, and when Wang Tao returned to the police force, Yi Qing's side was not as smooth as he imagined.

Qian Hui came to interrogate him in the middle of the night for a day, but he turned it over and turned it over to those few words, and just went to the laboratory building to go around with one bite, and did not see anyone, and of course did not kill anyone.

In the afternoon, the results of the forensic examination and trace examination came out: the fingerprints and footprints extracted from the laboratory contained Qian Huilai, and the blood type of Qian Huilai was consistent with the blood type of the blood stains on the laboratory floor, and it was also consistent with the blood type of ** in the body of the deceased Jiang Lina, both of which were type B.

Although according to the forensic examination, Jiang Lina's ** is mixed with type AB, that is to say, Jiang Lina's body is a mixture of two blood types, A and B, and Shi Mingkai's blood type is type A. From this point, it can also be proved that in addition to Shi Mingkai, there is indeed a second person who had a relationship with Jiang Lina on the day of the crime. And the person's blood type should be type A or AB.

The money will come, so much evidence, where are you going to escape!Yi Qing muttered to himself.
