"The deceased's name is Li Hao, male, eleven years old, local, studying in the second primary school, his parents are white-collar workers in the company, and his family is good, according to his teachers and classmates, Li Hao has a perverse personality, irritable, and often bullies his classmates, his parents say that they are busy with work and don't care much, Li Hao often plays games at home alone or on the street with a group of 'big brothers'. ”

"Forensic Doctor Zhen, what did you find?"

"Hmm...... The cause of death of the deceased was very simple, he was beaten badly before his death, resulting in a ruptured spleen and hemorrhage, which should have been caused by kicking and hitting the abdomen with his foot, judging from the degree of digestion of the food in the stomach, the time of death was around eleven to twelve o'clock last night, and this child ate not badly, eating a hodgepodge of seafood!"

"......" Lin Mu and the others looked at Zhen Zheng, he was excited at this time, and the others always thought that if this guy was not a forensic doctor, maybe he was a pervert.

"So, someone is taking revenge on him? Who is the 'big brother' he is messing with?"

"It's a group of children in junior high school, and the leading 'big brother' among them is called Zhao Gui"

"Well, talk to him. ”

At the entrance of the Eleventh Middle School, a thirteen or fourteen-year-old boy with dyed red and yellow hair was standing obediently in front of the forest at this time, looking down at his feet wiping the ground like a rooster foraging.

"Does Li Hao know?" "Yes, my little brother." The boy looked up triumphantly, and lowered his head as quickly as if he realized something. "Uncle policeman, we haven't done anything bad, we're just having fun. ”

"Where were you last night between eleven and twelve?"

"At home...... Write homework. The boy's confidence was obviously insufficient, and he also felt that he didn't look like a person who could do homework at all, and added, "Actually, I'm playing games in an Internet café outside." ”

"Which Internet café?"

"The 'Big Brother' internet café at the back door of the school. A few of our brothers were there often. ”

"Well, we'll come to you if necessary, and we hope you'll cooperate. ”

"Yes, Uncle Policeman. The boy looked up and replied earnestly. Lin Mu couldn't help but feel funny when he looked at him, and added, "Study hard, don't always think about playing games, and dye your hair back." ”

The boy looked at the distant trees and touched his hair, "No one appreciates such a trendy hair color?"

"This kid was playing games with me yesterday, and he was a regular customer, and he always skipped class to play games. But in the afternoon, he left, and also booked a private room to play games in the evening, but he didn't come. The owner of the Internet café looked at the photo of Li Hao in Lin Mu's hand and said.

"What about this, was it here from eleven to twelve o'clock last night?" Lin Mu changed it to Zhao Gui's photo and sent it to the boss.

"Oh, this kid is here, the student doesn't look like a student, he has a rooster head, it's hard not to pay attention. Lin Mu listened to the boss's description and imagined the picture, not knowing how funny it was.

Walking out of the Internet café, Lin Mu and Zheng Wei were discussing what to do next, when suddenly he saw a building under construction in the distance and muttered to himself, "Could it be him?"

"Who?" Zheng Wei looked dazed. "Let's go, Lao Zheng, come with me to meet a friend. ”

The construction site is dusty, workers are busy moving cement and rebar, and a tower crane is running. Didn't care about these two strangers. Yang Li was stacking bricks, and saw that Lin Mu was slightly surprised and quickly returned to normal.

"Yang Zhe's brother?"

"Yang Li. Yang Li replied without raising his head.

"Busy all the time?"

"Well, hurry. ”

"Was you rushing to work last night?"

"Well, it was busy until eleven or twelve o'clock last night. Yang Li glanced up at Lin Mu, and added, "Officer, I'm very busy, so I won't accompany you." With that, he pushed the cart loaded with bricks and left.

"Team Lin, who?" "Nothing. Lin Mu looked at Yang Li's busy figure thoughtfully, and the doubts in his heart deepened.

When Lin Mu returned to the police station, Bai Lan came to tell him that a child had come looking for him. "Is that you?" Lin Mu looked at him, from red and yellow hair in the morning, to brown hair, which was much more pleasing to the eye.

"Ahem, I'll give you a clue. Zhao Gui raised his head, like a child who wanted to be praised.

"Well, let's say, what's the clue?"

"At six o'clock yesterday afternoon, when I went to the Internet café, I saw Li Hao and another eldest brother eating in a restaurant. ”

"Who?"

"I don't know what his name is, I only know that everyone else calls him Brother Tiger. ”

"Brother Tiger?"

"I know where to find him, but you can't say what I said, or I'll get beaten. ”

"Okay, I promise you, you can say it. ”

"You can find him in that abandoned factory on South Street, where he lives. ”

"Abandoned factory, thank you. Lin Mu immediately got up, just walked to the door and turned back to Zhao Gui and said, "You are so handsome, and, don't follow those 'big brothers' to mess around, study hard, you will be very promising!" After speaking, Lin Mu took a few policemen to the abandoned factory, he didn't see the light of hope in Zhao Gui's eyes.

In one of the factories of an abandoned factory sat boys who were no more than seventeen or eighteen years old. The boy who took the lead was quite arrogant, with a tiger tattooed on his slightly muscular arm, and it seemed that he was Brother Tiger.

"Were you with Li Hao yesterday afternoon?"

"That stinky boy owes money and doesn't pay it back, and he wants to repay the debt when he buys a game console, so I won't break the law if I ask for money, right?"

"You hit him?"

Brother Hu's face changed slightly, and he said vaguely, "Hmm." Then he angrily asked, "Did he call the police?" ”

"He's dead, probably beaten by you. ”

Brother Hu's face suddenly turned like ashes, and he hurriedly explained, "Impossible police uncle, we are all measured in beating people on the road, and we won't beat them to death, and we won't hit the vital points, after all, no one wants to go to jail!"

"Who knows the severity of the hit, maybe you were too angry and kicked too hard. ”

"Kick? I didn't kick him! We all use our fists to solve the problem, never use feet, and those who use feet are villains, and I am a big brother...... Are you getting the wrong officer?"

Lin Mu looked at him silently, and then said, "Follow me back to the police station first." ”

Brother Hu, who was sitting in the interrogation room, fidgeted and kept defending himself by saying that he had never killed anyone. Lin Mu was watching him from the outside, but he was thinking about another person in his mind.

"Team Lin," Bai Lan walked over, "There is a new discovery in the trace examination department. ”

"We found some fine red particles on the deceased's clothes, which should have been left by the soles of his shoes when the murderer kicked him, and after testing, they were red bricks. ”

"Red bricks?" Lin Mu felt that his idea was about to be confirmed, but in his heart he hoped that it was not this person.

"Well, red brick is the basic material of construction, and it can generally be used on construction sites or when building houses. ”

Lin Mu suddenly felt that the blood rushed to the top of his head, and the truth that was about to come out made him involuntarily worried.
