Even if the normal way of handling the case is to secretly observe the suspect after identifying it, and then arrest him after knowing that he has found conclusive evidence, so that the suspect can admit guilt.

But Tang Tian had already shown his hole cards first, and they could only follow Tang Tian's rhythm.

"I don't know what you're talking about!" Tan Haopeng finally calmed down, lowered his head, and avoided his eyes from making contact with Tang Tian: "I am the victim's family, what right do you have to detain me? I want to complain to you, you obviously saw the suspect but did not pursue it, but found my fault here!"

"Sister Qu!"

At this time, the police who were in charge of visiting Xu Xiaozi on the seventeenth floor had already come down, and we went to Miss Xu's house, where she was fainted and was lying on the balcony, and the home was messy, and even the door was not completely closed.

"You continue to collect evidence, Xu Xiaozi's home should be able to leave very obvious clues, remember, focus on checking the possible traces in the stairway! All clues must be found out quickly, and let Xu Xiaozi wake up as soon as possible!"

Tang Tian praised Qu Liu's weak reaction, he understood that Qu Liu's words were not actually for the policeman, but to deter Tan Haopeng!

What Qu Liuwan said, even if she didn't say it, the police who collected evidence would do it.

Sure enough, Tan Haopeng's hands began to cross uneasily.

"Mr. Tan Haopeng, if you have made up your mind not to speak, then please cooperate with us and go back with us tonight, it is necessary for me to remind you that what you do may directly lead to the escape of your wife's murderer!" Qu Liuqiao continued to persecute Tan Haopeng.

"No, we are responsible for this case. Xiang Yu, the old fox, also came out.

Tang Tian was a little surprised, when did this old fox leave the Special Investigation Bureau? Could it be that he came out with his front and back feet, or did he come out earlier?

However, it can be seen that he is not indifferent to this case, and as Jia Zuozhen said, he is handling the case independently.

"I have conclusive evidence that he did it, and this man was taken by me today. Xiang Yu glanced at Tang Tian, "You are qualified, my tickets will be given to you." ”

"No, I won't go with you!" Tan Haopeng was still resisting, "In today's case, I must find the murderer!"

"Don't resist anymore, even for the sake of your daughter's heavenly spirit. When the old fox said this, Tan Haopeng's expression suddenly froze, and he no longer resisted, like a wooden man, letting Tang Tian press him to stand up and walk towards the elevator.

"Did you already know that he did all this for his daughter?" On the way back, Tang Tian asked Xiang Yu in a low voice.

"I took over this case not much earlier than you, all of this was checked last night when I was sitting at Xu Xiaozi's house. Xiang Yu shook his phone.

Tang Tian had to be convinced, the old fox was indeed one step ahead of him.

In fact, why didn't he find out that Tan Haopeng was a family of three? It's just that there is nothing definite, and he won't say it.

When Xiang Yu and Tang Tian pressed Tan Haopeng back to the base, it was already more than four o'clock in the morning, and Jia Zuozhen had already prepared an interrogation room, and everything that should be there was available, which was no worse than the professional equipment of the police station.

Tan Haopeng, male, 35 years old, graduated from Angang University with a master's degree. Specialist in psychology. Xiang Yu flipped through the documents in his hand and hit the searchlight on Tan Haopeng's face.

"You don't have much time, tell the people who know your plan as soon as possible, so that we can catch your wife's killer as quickly as possible. ”

"I told you, I don't know!" Tan Haopeng was still stubbornly resisting.

"Okay, let's talk about the previous two murders and one attempted murder!"

Tan Haopeng's psychological quality is good, and he is still insisting: "I don't know anything, I don't know what you're talking about!"

He bowed his head and his voice was low.

Tang Tian was watching from the sidelines, now it was the old fox's home field, and he needed to observe how much the old fox was capable of.

Although it had not been more than twelve hours since he came into contact with this case, Tang Tian had already felt that this case had nothing to do with the case five years ago.

"What? Or don't you want to say anything? Then you take a look at this first. Xiang Yu wanted to find a tablet with a video playing in it.

In the elevator picture, the early picture is full of snowflakes, and nothing can be seen.

But two minutes later, the picture began to become clear, this was an elevator, there was a little girl in the elevator, standing alone in the elevator, Tang Tian could see at a glance that this little girl was Tan Haopeng's daughter.

Soon after, the door of the elevator was opened, and a person walked in from the outside, it was Xu Xiaozi, who lived on the seventeenth floor.

After Xu Xiaozi saw the little girl standing alone in the elevator, she seemed to have said a few words with a concerned expression, but the little girl just kept shaking her head.

Then the elevator rose from seventeen to nineteen floors, the first deceased Fang Wen appeared, Fang Wen with a proud expression stepped into the elevator, just glanced at the two people in the elevator, and then the elevator came to the fourteenth floor, Cai Xin, who was dressed charmingly, walked in, and there was no conversation between several people.

The elevator reached the first floor, and the three women inside stepped out of the elevator one after another, leaving only the little girl alone.

The elevator door closed again, and this time there were large snowflakes in the picture again, and nothing could be seen clearly, and when the surveillance screen was restored again, it was already a minute later.

At this time, there was still only the young girl in the elevator, but Tang Tian immediately noticed that the button leading to the top floor in the elevator was pressed red!

And the little girl has an extra lollipop in her hand, and she is eating it with relish!

The elevator quickly reached the top floor, and when the elevator door opened, the little girl looked happy, as if she had seen something amazing, and ran out in a hurry.

At this point, Xiang Yu suddenly spoke: "This is a video from seven months ago, I think this is also your motive for the crime, right? Because on that day, there was a case of falling from a building! The deceased was this three-year-old girl." At that time, there were also a large number of doubts in this case, even if the deceased reached the top floor, she still needed to walk a flight of stairs, and the open-air platform on the top floor was also guarded, so such a small child should not be able to climb up, that is, it was impossible for her to complete the process of falling from the building alone. ”

"Yes, but you didn't find out the results! Just settle the case in a hurry! You policemen only know how to eat dry rice!" Tan Haopeng's expression was hideous.

"So you can only choose to take revenge on your own?" Xiang Yu suddenly asked sharply.

If the psychological quality is not good, maybe he will answer a 'yes' word immediately, but Tan Haopeng is a psychologist after all, he squinted his eyes and regained his composure: "I don't know anything." What are you trying to prove in this video? These three women saw my daughter, so I must be their killers?"

"Then I'll show you another video. Xiang Yu clicked on the tablet a few times, followed by a snowflake that lasted for more than ten minutes, and there was nothing in it.

"Are you trying to humiliate me with this thing?" Tan Haopeng laughed angrily.

Xiang Yu shook his head and said: "This is the picture in another elevator in your building at the same time, I found this video, just to find out who your daughter had contact with before entering the elevator." And obviously, that person is through the second elevator to complete the interaction with the daughter, for example, let your daughter stay in the elevator honestly......"

Xiang Yu turned the screen to the first video: "If she really stays in the elevator quietly, she will get some rewards, such as the extra lollipop in your daughter's hand in the back, and the person who remotely controls your daughter, the process of his possible appearance in the picture is disturbed by some kind of extremely strong shielding signal, so that we can't see the true face of that person." ”

"So what?" Tan Haopeng looked at Xiang Yu with a smile.

"So I want to say that if you want to really find the murderer of your daughter, or even your wife, it's best to tell us the truth, the other three people you killed are all innocent. ”

Xiang Yu narrowed his eyes: "I'm not here to make you happy. I can responsibly tell you that what is not visible to the naked eye, technology can do. Even if someone can easily see something with the naked eye, they can spot something. ”

Xiang Yu glanced at Tang Tian: "For example, this person next to me, I think he should be able to help you restore the crime process that you can't see through this blurry video now." ”

Tan Haopeng raised his head and stared at Tang Tian, some people's eyes are indeed different from ordinary people, which has been verified by facts, because of a certain variety show, people all over China have seen it.

As soon as the old fox saw that there was a play, his tone of voice became faster and faster: "For example, how did that person get in touch with the girl, how did he leave, how did he coax your daughter through another elevator, etc." ”

Tan Haopeng raised his face, this time his gaze was fixed on Tang Tian's body, but after a while, he still said: "I have nothing to say, I am weak by nature, and I have no enemies." ”

"yes. Xiang Yu flipped through the materials in his hand and handed a few of them to Tang Tian, "I have investigated you and found that you are indeed indifferent by nature, and you are usually a person in the company, and you are a good person." And although you are studying psychology, most of the time you tend to be academic, you have no clients, no circle of friends, and you go home immediately after work. For the past few years, you've been almost always at home and in the middle of the institute, so it's hard for us to find out who your enemy really is. ”

Xiang Yu still did not give up: "In today's social environment, it is impossible for a person to be completely invisible, and it is even more impossible for the suspect to take the shielding equipment with him at any time, he can block the surveillance video in the elevator, but the video in the community, as well as the surveillance video around the community, do not have the ability to care, and these, I can find." Even without you, we can find that person, just a little slower. ”

Tan Haopeng's body began to tremble: "Really...... Really? I ...... There really are no enemies, and I can't think of any enemies of myself. But he ...... But he knows everything about me! He knows everything I've done, and he's constantly hurting me, my family, and my children! I want to know what all this is for......?!
