Among the three, the child was the first to be unable to calm down. He asked his father, "Dad, there will be no problem, right?"

Dad glared at him, "Now you know you're scared?"

"It's been so late. If you complain, go home and talk about it." Mom sat between the father and son, obviously trying to smooth things over.

She looked around and lowered her voice and said, "I noticed everything when I came. I don't worry about the others. Only Zhang Haoran, why did this kid come with grandma? His grandma doesn't know that matter, don't miss it then."

Dad touched his forehead irritably, "Let's just bite the story we made to death later. Even if someone says it's missed, it doesn't matter. Anyway, the police will eventually go to the school to investigate, and the school will find a way to make things happen."

Mom asked again, "Hey, you said, would these policemen call us here for money? Maybe they can get rid of it with some benefits."

Dad shook his head, "Unless there is a clear hint, we must not raise money, be careful, don't get the old stalls cleaned up and get a charge of bribery."

Here, the three people in the conference room were talking, but the father and son in the conference room had already had a fuss.

"What's going on?! You police are too disrespectful to people? Just call them and leave them alone? What does it mean? Are you playing with us? Do you know who I am?..."

Wu Cuo thought for a moment and said to Xiaobai and Minghui: "You two are responsible for the conference room. Such people are bluffing and loving face. Don't fight him. Remember eight words: ask polite questions and listen first.

Since they have already compiled a story about Niu Xiaojie's death, let's listen carefully.

Understand this story thoroughly and prepare for the inquiry of the account.”

"Okay."

It can be seen that Xiaobai and Minghui were both nervous and excited. Wu Cuo patted their shoulders, "It's okay, put on the headphones, you can hear me when I talk. I will help you here."

Conference room number.

When Xiaobai and Minghui arrived, their son was quarreling with their father.

It is enough to show that behind every naughty child, there is a bear parent, and the children’s various bad deeds have been learned from their parents.

"Two guys, I'm sorry, I'm waiting for a long time." Minghui entered the door and said hello while signaling them to sit down.

"What? Let's just let us go for a minute, let's forget it?" Dad refused to sit down, staring at the two young detectives with his neck and staring at him.

Minghui didn't care about the father and son, and pulled Xiaobai down first and continued, "We wanted to come in just now, but seeing that you were calling, I didn't bother you.

Since you know our leaders, you must also know that we little detectives are just orders that we are interested in, and we are not deliberately causing trouble for you."

The father and son finally sat down, Minghui smiled and continued, "That's right, please calm down, let's start asking, so as not to waste your precious time."

"Then you ask."

With the permission of his father, Xiaobai said to his son: "Have you seen that video of beating Niu Xiaojie?"

The son nodded.

"Do you guys often beat Niu Xiaojie?"

"No, that time in the video, and we didn't beat people for no reason, so who told him to mess with us first."

My son's face does not blush when he lies.

"Is this only this time? It doesn't matter. We will continue to investigate. If we can find this video, we can find other things. It just takes some time."

Xiaobai's irrelevant statement made his son nervous. He glanced at his father, and a panic flashed through his eyes.

Obviously, there are other video materials.

The father received his son's gaze and interrupted, "Hey hey, even if he bullies him, what's wrong? My son is at most violating the school rules and regulations. The school can give him a punishment. Do you need to take care of it? If you want to take care of it, the Municipal Public Security Department? Are you doing it too broadly?"

Minghui explained: "Niu Xiaojie has disappeared and his whereabouts are still unknown, so what we are investigating is not a simple campus bullying case..."

"His disappearance has something to do with my son?"

"No one said it was related. I would like to emphasize it again. We are just asking routinely. If you want to prove that Niu Xiaojie's disappearance has nothing to do with your son, just answer our questions truthfully." Minghui turned to his son and said, "Isn't this difficult?"

The son said it was not difficult, but he looked at his father again, obviously not in agreement.

Everyone who stayed in the office of the serious case group also realized that Xiaobai and Minghui had a clear division of labor, Xiaobai was the judge of his son, and Minghui was responsible for stabilizing his father.

The two cooperated tacitly and were not confused.

Dad pondered for a moment and told his son: "Then tell the truth, cooperate with the police and don't cause trouble for me."

As he said this, the father squinted his son slightly, obviously sending some news.

The son was stunned, then understood and said to Xiaobai and Minghui: "We do bully him often, but his disappearance really has nothing to do with me."

"When was the last time you saw him? Where was it?" Xiaobai asked.

"Month issue, after school, I saw him in the school bathroom. At that time, we just wanted to... teach him a lesson. Maybe he was angry that day. He was like a mad dog, and suddenly broke out, hitting us and hitting us with his head.

As a result, he asked him to run away. Before leaving, he said that his brother was a policeman and said that he wanted to go back and ask his brother to teach us a lesson.

The next day we wanted to seek revenge on him and retrieve the lost part yesterday. We only realized that he hadn't come to school until after school, and he never came since then. I really don't know where he went."

Xiaobai continued to ask, "Before this, have any other police officers asked you to find out about the situation?"

"No."

Wu Cuo's voice came from the headphones: "Ask him why he remembers the date so clearly. Also, Niu Xiaojie ran away, did they chase after him? If he chased him, how did he chase him, and where did he chase him?"

Xiaobai asked questions one by one by Wu Cuo's advice.

"I can remember the monthly issue because it was Friday. Our monthly issue had a unified examination for the whole school, which was the Monday of the second week. Although I was not good at studying, the unified examination was still very important, so I remembered it."

But when asked whether to chase Niu Xiaojie or not, his son became entangled, "Well... this... probably didn't chase him, I can't remember it."

"Can't remember it?" Xiaobai thought for a moment and continued: "There are two doors on the left and right of your school's bathroom. Which door did Niu Xiaojie run out from? Did you see him running with your own eyes, do you always remember this?"

The son looked at his father again, and his father was an old monk who entered into meditation. He simply did not look at his son. The son had to answer: "He ran from... from the left."

...

To see through the other party’s lies is an interrogation skill that every criminal police officer must master. The specific method is nothing more than asking more questions and asking more details.

Obviously, the stories made up by these people are not very clever and cannot help but ask.

The inquiry in the meeting room of the number was over. When Minghui and Xiaobai left, the father and son no longer had the arrogance at the beginning. The son asked timidly: "Dad, I have answered... no problem, right?"

There was obviously a layer of sweat on his father's forehead. He didn't answer his son, but just lit a cigarette.

In the office of a group of serious cases, Wu Cuo and Yan Ruyu looked at each other.

"Next, come to the conference room?"

"Well, what do you think?"

Wu Cuo thought, "The grandparents and grandchildren in the conference room are the easiest to break through, especially grandma. However, seeing that this grandma is particularly doting on her grandson, she probably listens to her grandson everything. If her grandson doesn't let her say it, she won't say it."

Yan Ruyu nodded, "So, we have to separate our grandmother and grandson."

"Split up? Absolutely not possible. The police asked the minors to need a guardian to be there."

"Who said I want to ask minors? The law does not stipulate that if I ask the elderly, I must have a guardian."

"You mean, ask grandma?"

"Anyway, my grandson has made up his mind to tell us stories, so don't waste time on him, and ask grandma alone. This time, Minghui and I went there. The old lady is old and can't stand the stimulation, so she has to pay attention to her inquiries."

Yan Ruyu took care of her hair that was a little messy because she stayed up late, and said while walking out: "Oh, by the way, I'll ask grandma about this alone, so that everyone in the other conference rooms would know. Aren't they worried about the old lady letting go? I'll let them worry, the frightened bird, do you know?"

"No problem, leave this to me!" Minghui followed Yan Ruyu and said loudly.
