Solving the case: Combining the police dog's olfactory genes at the beginning

Luo Fei and Wang Lei just left Wang Wenying's house

"No wonder Zeng Tianming wanted to kill his own son. It turns out there is such a story in it." Wang Lei sighed, and then asked: "Now that we know the reason why Zeng Tianming hates his own son, do you think Zeng Tianming can do it this time?" Confess?"

Luo Fei thought for a while and replied: "There is a 70% to 80% certainty that the more a person hates, hates, and is obsessed with one thing, the easier it will be to break down his psychological defenses. Of course, you won't know until you try it."

At twelve o'clock at noon, Luo Fei and Wang Lei returned to the criminal police team.

He immediately found Zhao Donglai and Yang Su and reported the situation to them.

After Zhao Donglai learned about the situation, he immediately held a temporary meeting. The focus of the meeting was to discuss how to interrogate Zeng Tianming, how to break down Zeng Tianming's psychological defense, and let Zeng Tianming take the initiative to confess everything.

After discussing for almost an hour, the tone of the interrogation was finally set, with stimulating language and coercion and shock.

At two o'clock in the afternoon, the criminal police team conducted a second interrogation of Zeng Tianming.

The person in charge of the interrogation is still Zhao Donglai, and Yang Su records it.

Zeng Tianming was taken into the interrogation room again.

"How many times have I told you that I didn't kill anyone. I was really unjust. You didn't catch the real murderer, but you kept spending your time on me. I really don't know what to say to you." Zeng Tianming said. Very helpless.

"That's enough. We police will not wrongly accuse a good person, but we will not let go of a bad person. You say we have wronged you? You said you did not kill your son. Do you dare to touch your own conscience and say that?" Zhao Donglai was angry. He drank and said coldly.

"Then there's nothing to be afraid of." Zeng Tianming looked very unconcerned, and then said seriously: "I, Zeng Tianming, swear on my conscience that I definitely did not kill my son."

"I really don't know how there can be a father like you in the world." Zhao Donglai shook his head.

"Whatever you say, I didn't kill my son anyway." Zeng Tianming vowed.

"Do you know what this list is in my hand?" Zhao Donglai took out a list.

Zeng Tianming glanced at the list and said unhappily: "How do I know what this is?"

Zhao Donglai said: "This is a DNA test report. At that time, our people suspected that you killed your son. We felt that a father would not kill his son, so we took your hair and conducted a DNA test with the deceased. After comparison, the identification report shows that the DNA matching degree is 99.9%, which means that the deceased is undoubtedly your biological son."

When Zhao Dong finished speaking, Zeng Tianming's calm face showed some emotional fluctuations, but he controlled them very well.

"Xiao Guang must be my biological son, otherwise whose son could he be?" Zeng Tianming asked.

"I thought you didn't know! I know the reason why you don't like or even hate your son? Is it because Xiaoguang looks like your wife's first love?" Zhao Donglai asked coldly.

"Who said that, my son must look like me, how could he look like that scumbag?" Zeng Tianming became obviously excited when he heard Zhao Dong said that his son looked like Kang Jian.

"Really? Then why do we know that at your high school class reunion, everyone regarded the child as the child of Kang Jian and Wang Wenying?" Zhao Donglai said.

"Nonsense, there is no such thing." Zeng Tianming retorted with a livid face.

"Don't explain. You hate your son because he looks like your wife's first love. And Wang Wenying was with you because she mistakenly thought she was pregnant. Wang Wenying From the beginning to the end, there is only Kang Jian in your heart, so you have always doubted Wang Wenying's feelings for you. At the same time, you have also always suspected that Zeng Xiaoguang is the child of Kang Jian and Wang Wenying. You are even more disgusted that this child looks like Kang Jian, so he was blackmailed by Xianren Tiao for five years. When you have 100,000 yuan, do you think of killing your own son?" Zhao Donglai asked loudly.

"No, you made this all up." Zeng Tianming shook his head vigorously in denial.

"No? Don't lie to yourself? Although you are with Wang Wenying, you can't let go of Wang Wenying and Kang Jian's time together. You can't forget that Wang Wenying and Kang Jian were together. The appearance of the child makes you even more worried. The jealousy and resentment in your heart is getting deeper day by day, so you often go to bars and KTVs to take revenge on Wang Wenying, and even kill your own son in the end. In the end, you are a narrow-minded and selfish guy. "Zhao Donglai pressed forward step by step and continued to scold.

"That's enough." Suddenly Zeng Tianming yelled, and then stared at Zhao Donglai with murderous eyes.

"Wang Wenying told you this, right! That's right, who else but Wang Wenying can know this." Zeng Tianming looked like he was gritting his teeth.

"But why does Wang Wenying do this to me? Isn't it all because of her that I am like this? I used to like her so much. For her, I would give my life and even accept other people's children to marry her, but what about her? ! What she always carries in her heart is the scumbag who abandoned her."

"I originally thought that time would make her forget about that scumbag Kang Jian and she would slowly fall in love with me. But when that guy Kang Jian reappeared, Wang Wenying's eyes were full of Kang Jian. I really couldn't understand. What's wrong with that scumbag Kang Jian? It was clearly Kang Jian who gave up on her and hurt her, but she still can't forget him, which makes me very painful and angry."

"And what makes me even more angry is that Wang Wenying secretly contacted that scumbag Kang Jian without telling me, and even drank coffee together. Does she think I don't know? I know everything, but I just like her so much, even though I don't want to leave her even now, I love her so much, I only hate that bastard Kang Jian."

"I hate Kang Jian. Yes, I killed Xiaoguang. I didn't want to kill Xiaoguang, but he looks so much like that scumbag Kang Jian. Every time I see him, I will think of that scumbag Kang Jian. Thinking of that scumbag being with Wang Wenying, and the two bitches Yang Cheng and Zhou Zhi setting a trap for me and blackmailing me for 500,000 yuan, I thought of killing Xiaoguang."

"It can be said that Wang Wenying must bear at least half of the responsibility for what happened to me." Zeng Tianming said angrily, as if he wanted to vent all the suppressed and dissatisfied emotions in his heart.

Later, under Zhao Donglai's continued questioning, Zeng Tianming also explained the entire details of the crime. On Saturday, Zeng Tianming went to the city, but came back from the city before 2 o'clock. After passing Yunnu Street, he passed Ma Zeng Tianming stopped the car when he was in the river, and then took a ride into Ningjiang County.

He picked up the child in the alley that Zeng Xiaoguang passed by after school, saying that he was taking the child to swim. In order not to be seen, Zeng Tianming took the child through Longxugou on the back mountain.

I took my children to the Longxugou Reservoir. Not many people usually come to this place.

When the child happily took off his clothes and went for a swim in the pond, Zeng Tianming checked around and saw that no one was nearby. Zeng Tianming asked Zeng Xiaoguang to swim to him. The child never thought that his biological father would kill him, so he swam over happily. .

Zeng Tianming pretended to touch the child's head, and then pushed the child's head into the water. The child tried desperately to come out of the water, but a nine-year-old child was not as strong as an adult.

After a while, the child completely stopped moving.

After confirming that the child was really dead, Zeng Tianming hurriedly left the scene, then went to the highway, took a taxi out of the county, returned to Mahe, and then got out of the car and drove his own car back to Ningjiang County.
