After Li Tianyi listened to Zhang Tao, he had a general understanding of Wu Zhengfu's death.

It turned out that these days, Zhang Tao and his team of eight people divided into two groups to take turns to interrogate Wu Zhengfu. Zhang Tao and Hu Tianyong each led a team.

At 10 o'clock last night, when the interrogation ended, Hu Tianyong led his team to arrange sleeping according to the previous deployment.

The place where they slept was a coat room. Every time he slept, one of them accompanied Wu Zhengfu to sleep in the inner room to prevent Wu Zhengfu from doing anything irrational.

In the outer suite, Hu Tianyong and the other two slept on the sofa and bed respectively, guarding the entire suite to prevent Wu Zhengfu from running out of the inner room and escaping outside.

Moreover, the lights between the inner and outer coats are on, and there are surveillance cameras on them for 24-hour uninterrupted shooting, so as to ensure all-round monitoring of Wu Zhengfu.

According to common sense, it is impossible to give Wu Zhengfu any chance at all with such a tight armament.

But he didn't expect that at about four o'clock in the morning, Hu Tianyong got up and went to the inner room to inspect, but found that Dou Zhongjie, a team member who accompanied Wu Zhengfu to sleep inside, had fainted on the bed, and Wu Zhengfu was wearing a shoelace around his neck and had died of anger.

After Li Tianyi heard this, he couldn't help frowning, and said in a deep voice: "Zhang Tao, you immediately notify that from now on, all office staff in the entire office area are not allowed to leave, and at the same time, thoroughly check whether anyone who should be stationed in the office area last night has left." ”

Zhang Tao hurriedly nodded to show that he understood, and immediately disagreed.

Although it was only four o'clock in the morning, Li Tianyi couldn't sleep at all after receiving this call, and his strong sense of responsibility drove him to get up, put on his clothes, and drive towards the East Development Zone alone.

Coming to the residence of the special case group of the Commission for Discipline Inspection, at this moment, the station of the special case group was in a dark state, and at the door, Zhang Tao was counting the number of people with his mobile phone as a light source.

Because at this moment, the automatic retractable door outside the small building has been closed, but it has lost power supply, Li Tianyi's car can only be parked outside, and he jumped over the automatic retractable door.

At this time, Zhang Tao had already counted the number of people, came to Li Tianyi with a sad face, and said: "Secretary Li, I'm sorry, there was a huge mistake in my work......

Li Tianyi waved his hand and said: "Now is not the time to determine who is responsible, let's find out the matter first, and then talk about it, has the number of people at the scene been investigated clearly? Has anyone left suddenly? Why is the scene dark? Is there a problem with the power supply system here?"

Zhang Tao said with a miserable smile: "Secretary Li, when Hu Tianyong got up to inspect, he found that the lights of the entire task force station had completely disappeared, and even the UPS uninterruptible power supply system in the information center had problems, so now there is no power supply for the entire task force station."

I checked the number of people living in the house just now and found that there was a missing security guard in the doorman duty room. No one at the scene knew where he went. After our preliminary inspection, it was found that the power supply system of the task force station was artificially damaged, and now we have contacted the power system staff to rush over to repair it. ”

Li Tianyi asked again: "You said before that when Hu Tianyong was on patrol, the person who slept with Wu Zhengfu was called Dou Zhongjie, right?"

Zhang Tao nodded hurriedly, pointed to a person standing next to him with his hand and said, "Secretary Li, he is Dou Zhongjie." ”

Following the direction of Zhang Tao's finger, a thirty-five or sixteen-year-old thin man stood out from the crowd, nodded to Li Tianyi with sweat and said: "Hello Secretary Li, I'm Dou Zhongjie, I'm sorry, because I didn't work properly, I was knocked out by Wu Zhengfu when I was asleep, so he found the opportunity to commit suicide, this is all a mistake in my work, I will check on you." ”

Li Tianyi's eyes glanced at Dou Zhongjie coldly, and suddenly said, "When did you faint?"

Dou Zhongjie said with a wry smile: "I don't know when I fainted, but there are some bruises on the back of my neck, I suspect that when I was asleep, Wu Zhengfu hit me on the back of the neck with a heavy punch from behind, causing me to faint to the ground, and he took the opportunity to take out the key to lock the door from me, gently opened the door, squeezed the shoelaces on the top of the door frame, and then committed suicide by putting them on his neck." ”

Li Tianyi said lightly: "It sounds like your explanation still makes sense." ”

Dou Zhongjie breathed a long sigh of relief.

Li Tianyi turned his head to look at Zhang Tao and said: "Zhang Tao, you immediately contact the Wuzhou City Public Security Bureau and ask them to send someone to cooperate with our city-wide search for the fleeing security guard, I suspect that the power system of the small building handled by our Commission for Discipline Inspection was destroyed, which should be his handiwork."

Because in this way, after the power system is destroyed, the UPS power supply system is also destroyed, so all the monitoring systems in the entire small building are also invalid, therefore, no one can see clearly, no one can know what is happening in the small building. ”

Hearing Li Tianyi say this, Zhang Tao gritted his teeth and said: "This security guard is really hateful, this is obviously premeditated." It seems that some people don't want Wu Zhengfu to get out alive. ”

Li Tianyi nodded: "Obviously, this is the case, because if Wu Zhengfu really explains something, I am afraid that many people will be implicated, so they are scared, so they will do everything possible to put Wu Zhengfu to death." ”

Speaking of this, Li Tianyi's eyes suddenly looked at Dou Zhongjie and said, "Zhang Tao, control it to the end, he is an internal ghost." ”

Dou Zhongjie, who was already full of lightheartedness, showed a look of shock and anger on his face, looked at Li Tianyi and said, "Secretary Li, what do you mean by this?

Li Tianyi sneered and said, "Dou Zhongjie, haven't you noticed that there is something wrong with what you just said?"

Dou Zhongjie frowned: "What's the problem?"

Li Tianyi sneered and said: "What you just said is, why do you say that I am an inner ghost? From the tone of your voice, it can be inferred that you are very confused now, and you can't understand why I can judge that you are an inner ghost, so you have such doubts. Actually, I wasn't completely sure that you were an inner ghost, but this question you just asked me to directly confirm that you are an inner ghost.

Of course, you also overlooked one thing, or maybe you did something that added to it, and it was this incident that made me sure that you are an internal ghost. ”

Dou Zhongjie glared at Li Tianyi with anger on his face, but he didn't say a word, because he knew that the more he said, the more information Li Tianyi would get.

Zhang Tao asked: "Secretary Li, how are you sure that he is an internal ghost? Dou Zhongjie usually performs very well, and he also graduated from the training class with us. ”

Li Tianyi said lightly: "Zhang Tao, think about it carefully, if Wu Zhengfu really committed suicide, then it is necessary for that security guard to cut off and destroy the power supply system of our entire office building of the Commission for Discipline Inspection?"

Why would he want to destroy the power supply system of the whole building? The reason is simple, he wants to completely disable the video surveillance system of our entire system. In this way, no one can know how Wu Zhengfu died.

If you look at the scars on Dou Zhongjie's back neck, if these scars were hit by Wu Zhengfu, then judging from the traces of the scars, it should be that the bruises on the top are relatively large and heavy, and the bottom is lighter, because if an ordinary person wants to beat a person to a coma without any foreign objects, then the only way is to use a fist, if it is a fist, the scar must be large above and small at the bottom, because a person's fist must be homeopathic when exerting force, not against the trend.

But you look at the scars on Dou Zhongjie's back neck, although they are also traces of fist blows, but these marks are obviously small at the top and big at the bottom, which shows that when the fist hit his neck, it was hit in the opposite direction, that is, against the trend.

So just to explain one point, the scar on Dou Zhongjie's back neck was beaten by himself, not by Wu Zhengfu. ”

Zhang Tao and the others immediately carefully looked at the scars on their necks after the end, and looked carefully, and sure enough, as Li Tianyi said, the scars were small at the top and large at the bottom.

Zhang Tao immediately looked at Dou Zhongjie with anger on his face, gritted his teeth and said, "Dou Zhongjie, why did you betray us?"

Dou Zhongjie looked at Li Tianyi with a miserable face, and said, "Secretary Li, why are your observations so meticulous, can you judge the situation at that time just by the scars? You shouldn't have this level." ”

When Dou Zhongjie said this, Zhang Tao's anger was already incomprehensible, and he was now eager to strangle Dou Zhongjie to death directly, because it was already certain from what he said just now, and it was equivalent to admitting that he had done it.

Li Tianyi smiled disdainfully and said: "Comrade Dou Zhongjie, you may not know it, I was the director of the Public Security Bureau, so I am relatively proficient in trace identification and the detection of criminal suspects, especially in trace identification, criminal psychology, and even human footprints. So, after seeing your scars, I can cut it off, it's fake.

In fact, if it weren't for this security guard who destroyed the power system of this small office building, I wouldn't have been able to suspect you so quickly, because there is only one explanation for his sabotage, that is, he wanted to cover up the real reason for Wu Zhengfu's death, and it was you and Wu Zhengfu who slept together at that time, so Wu Zhengfu's death must have something to do with you. ”

Listening to Li Tianyi's analysis here, a trace of blood suddenly flowed from the corner of Dou Zhongjie's mouth, and then, blood overflowed from his nose and ear holes and even the corners of his eyes, he sat on the ground in pain, smiled at Li Tianyi, and said: "Li Tianyi, you are so powerful, but I am going to die, you will never know who is behind the scenes." I'm really unwilling. ”

After speaking, Dou Zhongjie's body stiffened and he didn't move, but his eyes were still wide open, as if he couldn't bat himself.
