The two came to the community where Wang Haiyang lived, the south of the community is Fuxing Road, the north is Zhongchang Road, there is a gap between the two roads, so there is a long step at the south gate of the community.

Song Feipeng did not take the north gate, but parked the car at the supermarket near the south gate and climbed the steps with Wang Bing.

Walking to the top of the steps, he looked back down, and Wang Bing asked, "Captain, what are you looking at?" ”

"It's so steep!"

"yes!"

"Seven years ago, a kid fell here and died."

After saying this, Song Feipeng walked straight into the community, inquired all the way to find Wang Haiyang's house, knocked on the door but no one came, Wang Bing said: "We may be early, they are out of school at half past five." ”

"Just what I want."

Seinfeld went to knock on his neighbor's door again.

A neighbor's aunt opened the door and asked them what was the matter, and Song Feipeng showed his ID, "We are here to find the next door, but the person is not there, can I find out the situation with you?" ”

"Yes, what do you have to ask?"

"What does his family do?"

"Xiao Wang seems to have worked in an orchestra before, playing the violin, and I can often hear him playing the violin from the balcony. Later, I quit, probably in business! ”

"He has a son."

"Yes, it's still in school, hey, you can't be looking into their school's case, right?"

"You know that, too?"

"My son is also going to school in Yuying, what, do you suspect this?"

"No, no, it's just an ordinary investigation, Wang Haiyang happens to be a student in the deceased's class, and we will also visit other students." Seinfeld habitually explained, "How is the family relationship in this family? ”

"Well, I feel that their family is really strict with their children, who go to various interest classes and cram schools when they are very young, and do not come out to play during the summer vacation, but read famous books and learn violin at home. Xiao Wang is really strict, I often hear him scolding the child at home, because of this, Wang Haiyang's grades are top in school, I often say to my son, you have someone Wang Haiyang is half as good as enough. ”

"Has there ever been domestic violence?" Seinfeld asked.

"It doesn't seem like there's a ......"

"How did his mother die?"

"Sick, right? I don't know if we moved in a few years ago. ”

"By the way, do you know a little boy named Xu Zhou?" The Xu Zhou mentioned by Song Feipeng is the little boy who fell to his death in this community.

"I haven't heard of it."

"Okay, excuse me."

visited several neighbors in a row, and their evaluation of the Wang family was the same, the father was very strict in discipline, the son was very well-behaved and sensible, and the neighbors usually called uncles and aunts when they saw them.

None of them had heard of Xu Zhou, except for an old lady who had lived there for a long time, who said: "That child is poor, he fell to his death at the gate of the community at the age of eight." ”

"Where did Xu Zhou live before?"

"On this floor, door to door with Xiao Wang's house, he and Wang Haiyang often play together."

Song Feipeng's suspicion of Wang Haiyang added another layer in his heart, he judged that the murderer had murder experience before, but after checking all the murder cases within seven years and did not find any that matched the characteristics, then the murderer's last murder was not filed, and it was treated as an ordinary accident.

At the end of the questioning, Song Feipeng said: "Wang Haiyang was born in a single-parent family, strict family education, obedient and sensible, but these are all appearances, for children, the theme of life is communication, collaboration, conflict resolution, simply put, play, play is a social exercise, just like the little lion practice predation, is an important part of shaping children's growth, but he has almost no entertainment, such a nerd often behaves timidly and autistic, but the neighbor reacts, he usually has a very sweet mouth, and greets adults very politely!" It's paradoxical, he learned to disguise and cater to adults at a very young age, this kid is more complicated than we think! ”

Wang Bing didn't understand these psychological analyses very well, he said: "In short, is he suspicious?" ”

"The pent-up psychological energy will be vented through other means, there was a news before, a graduate student with excellent character and learning, quietly in the corridor every night; There are also some students who are particularly strict with their home education and go to the supermarket to steal things to decompress. How important are games, short videos, books for a person's mental health? Humanity is forced to conform to the social order every day, psychological energy is backlogged, and there must be some pastime to vent it!

"These superficial analyses can only deduce that Wang Haiyang has a problem, but it can't be directly concluded that he has a criminal heart, and I still need more information......" Song Feipeng looked at the door, "By the way, the murderer entered the campus through a broken fence and left from there, and the murder weapon was not found after searching the campus, which means that the murder weapon was taken away." I need to arrange a few people to keep an eye on Wang Haiyang's recent moves! ”

"I'll do it!" Wang Bing blurted out.

Song Feipeng glanced at him with strange eyes and said, "You don't use it, you still have to take care of your sister, I'll find someone else." ”

"No, Captain!" Wang Bing couldn't wait to say, "You can't treat me special because I have a younger sister, I've been a policeman for half a year, I want to make meritorious service, I really want to make meritorious service, it doesn't matter if I don't accompany my sister for a few days, she will understand!" ”

Wang Bing's eyes were very sincere, and Song Feipeng stared at him for a while, and said with a smile: "Okay, start watching from tomorrow!" ”

After thinking about it, Song Feipeng said again: "Why don't I go and help you take care of her?" ”

The next evening, Wang Yueyue was walking home with her head down sullenly, she had just received a text message from her brother, he was not coming back today, and she cursed this damn captain fiercely in her heart.

Walking into the unit building, Wang Yueyue took out the key hanging around her neck, but found that there was an uncle in a windbreaker standing outside the door, who was smoking, and when he saw her coming back, Song Feipeng extinguished the cigarette and smiled gently: "You are Wang Yueyue?" ”

"What!" Wang Yueyue took a step back, revealing a look of vigilance, "Who are you?" ”

Song Feipeng pulled out his ID.

"What's wrong with my brother!?" Wang Yueyue almost cried.

"What's your reaction, your brother is on a mission, please let me take care of you."

"What task? Is it dangerous? ”

From these conversations, it can be seen that this lovely sister really cares about her brother, and Seinfeld said: "Keep an eye on it, there will be no danger, but I can't go home at night." I'm here to cook you a meal. ”

"Thanks, I'll just eat instant noodles."

"At the age of growing your body, how can you eat instant noodles every day, I'll go grocery shopping first, what do you like to eat?"

"Lobster, abalone, sea cucumber, matsutake mushroom...... Wang Yueyue said several things in one breath, and she expected that the other party could not afford the food.

"I know your tastes like a little bit, okay, you wait at home!"

"Hey, hey!"

Before he could stop shouting, the strange man was already gone.

Wang Yueyue was writing her homework, paying attention to the movement outside, there was a stranger who was coming to cook for her, she was always uneasy, she sent a text message to Wang Bing, but he didn't reply for a long time.

Later, Seinfeld came back, carrying a large bag and a small bag, and said with a smile: "You can eat in half an hour." ”

He went to the kitchen to be busy, Wang Yueyue poked her head out curiously, only to see Song Feipeng skillfully cutting a grass carp, turned around and saw Wang Yueyue, and said: "It seems that you like to eat seafood, let me make a sauerkraut fish!" ”

"Who said I like seafood anymore! My last favorite thing is fish! ”
