The girl said: "Once I saw Wang Haiyang on the bus, there was an old lady next to me, with a cane, trembling, Wang Haiyang was sitting there listening to the headphones, motionless, his expression was very indifferent. ”

Wang Bing smiled: "Let me not give up my seat, this is purely my personal will." ”

The girl frowned and said, "Wang Haiyang is still bullying Wang Shanshan, I saw him make her cry." ”

"Really?" Wang Bing didn't expect there to be a second eyewitness, "Where is it?" ”

"Playground, after school...... I don't know what they were talking about, Wang Haiyang felt particularly fierce at that time, as if Wang Shanshan had some handle held by Wang Haiyang. ”

"When did you see it?"

"Just last month."

The next student to come to Wang Bing was Wang Haiyang, a little boy with glasses, who felt very gentle, with neatly combed hair and a straight sitting posture.

"I heard you're a single parent." Wang Bing said.

Wang Haiyang nodded calmly and said in a sad tone: "When I was seven years old, my mother died in a car accident. ”

"Did you go straight home after school last Saturday?"

"Yes."

"Some classmates reacted, you have a good relationship with Wang Shanshan?"

Wang Haiyang frowned, "I don't know who made the rumor, but once Wang Shanshan accidentally broke her foot, and I happened to be passing by, she was crying in pain, I asked if I wanted to take her to the hospital, maybe someone saw it, and I said nonsense there." ”

Wang Bing was a little surprised, Wang Haiyang's answer was too thoughtful, and his expression was a little deliberate.

Through the techniques that Seinfeld taught him to recognize lies, Wang Bing judged that the little boy was not only lying, but also hiding a deep truth.

He asked tentatively, "How do you know I'm talking about this?" ”

Wang Haiyang spread his hands, "Because Wang Shanshan and I usually don't talk, that was the only time we had contact." ”

It was another overly thoughtful answer, which made Wang Bing even more suspicious.

"But some classmates reacted that you hardly talk to girls."

"So what? I spoke to Wang Shanshan once, and I was guilty? What kind of feudal society is this? Wang Haiyang's tone was still calm, but Wang Bing heard a trace of anger from it.

"No, of course I didn't mean that......"

"So what does this have to do with the case?"

"Maybe it's related, maybe it's not related, I'm just collecting clues, what clues do you have to provide about this case?"

"I don't know, and I don't care, Teacher Liu has always had a bad reputation, for example, she doesn't deal with geography teachers very well."

After chatting a few words, Wang Bing collected Wang Haiyang's fingerprints, asked him to go back first, and then highlighted the name in his notebook.

After the day's investigation, back in the bureau, the investigators reported the situation to Song Feipeng one by one, Wang Bing mentioned Wang Haiyang, and Song Feipeng said: "Oh, that kid! I have a bit of an impression that we met once a few days ago on campus. ”

"Captain, do you think he's too mature?"

"Yes, probably because of the relationship between single-parent families!" Song Feipeng couldn't tell how it felt.

"Some classmates mentioned that there was something between him and Wang Shanshan."

"Really?"

"Someone witnessed that a month ago, Wang Haiyang and Wang Shanshan stayed on the playground after school, Wang Haiyang said something fiercely, and Wang Bingshanshan was crying."

Seinfeld rubbed his chin and groaned, "Wang Shanshan...... By the way, have you met this girl? ”

"See."

"The diary thing."

"I looked, and it ...... above"

"You see!?" Song Feipeng was shocked, "Did you ask her to bring it, or did she take the initiative to take it?" ”

Seinfeld's exaggerated reaction frightened Wang Bing a bit, and Wang Bing replied, "She brought the diary, and when I mentioned it, she handed it to me." ”

"What's up there?"

"It's nothing, it's just a diary of an ordinary junior high school girl."

Seinfeld stood up and walked around the office, having speculated that if Wang Shanshan took the initiative to hand over the diary, it would mean that the girl was suspicious.

The diary, which was confiscated by the deceased on the day of the crime, disappeared after the incident.

Now that it has been determined that the murderer killed in order to take something, and the diary is the only known item that has disappeared from the scene, then it cannot be ignored.

Seinfeld propped his hands on the table and asked sharply, "Have you ever asked, who saw her when she went to the office after school that day?" ”

"She said that after going to the office, she went home with her classmates, but when she went to the office, there was no witness."

"Maybe she didn't go to the office at all, how did the diary get back into her hands, and her relationship with Wang Haiyang ......" Song Feipeng raised his head, "There are secrets in the diary!" What you see has been tampered with! I found her house that day, she didn't want to show me the diary, and today she took the initiative to take it out, which is a remedial act! ”

"The more you describe...... The darker? ”

"Yes! From her standpoint, as long as the police have seen it, they will no longer suspect her, but in fact, the fact that she took the initiative to take out the diary is suspicious enough! ”

"Shall we focus on her?"

"I've already been to her house, there's no point in going again, the diary she gave shouldn't be the one that was confiscated, the murderer is a boy......"

Seinfeld began to flip through the information, and he was so immersed in it that he even forgot that Wang Bing was still standing here.

It was time to get off work, Wang Bing was worried about going back to cook for his sister, and asked in a low voice: "Captain, I'll go first!" ”

Song Feipeng said it three times before he came to his senses, "Huh? Why are you still here? ”

"I'll leave first."

"No, let's go to Wang Haiyang's house...... You'll be okay if you go back later, right? ”

"Oh, it's okay!"

"You're waiting for me at the door."

Wang Bing went out first, he called his sister and said, "The captain asked me to investigate the case together, I can't go back to cook tonight, you can eat instant noodles!" ”

"Huh? Dead captain stinky captain, overtime and no pay! My sister reacted violently.

"I volunteered, I'll come back later to bring you food, and you do your homework obediently."

"I'm done writing, I'm watching TV!" My sister's tone was very unhappy.

"Okay, okay!"

"Hmph, I hope this stinky captain disappears!"

With a "snap", my sister hung up the phone.

"Who are you calling?" Song Feipeng drove the car and parked next to Wang Bing.

Wang Bing got into the car and said, "Sister, I told her to go back later, and she said she could understand." ”

"Oh, I forgot that you still have a sister, it's hard to take care of her, right?"

"It's not very hard, she's very sensible."

"Why don't I make up some allowance for you, it's not easy." Song Feipeng tapped his fingers on the steering wheel and muttered.

"There's no need for the captain, the current salary can support the two of us, and besides, she will graduate soon, and she is going to take the police academy, so she doesn't have to spend money if she goes to the police academy."

Song Feipeng smiled, "A good example for my brother." ”
