When Lin Mu received the report, two days had passed, Zhong Sheng was killed in the alley, and Ruomi suddenly disappeared.

"The deceased's name is Zhong Sheng, male, 43 years old, the vice principal of Lily of the Valley No. 1 Middle School, with a wife and a daughter......"

"Why don't you say it?" Lin Mu looked at Zheng Wei who stopped, only to see him take a heavy breath and say, "The deceased was a pervert who had molested female students for a long time, and in his teacher's dormitory, several perverted videotapes were found, among which there was also the missing Ruomei.

According to the principal of the school, on the evening of the 14th, Ruomei called the Chinese teacher in the class and said that Zhong Sheng was plotting against her, and then the teacher found another female teacher to notify the principal, and met Zhong Sheng's wife on the way, and Zhong Sheng was caught red-handed.

Later, after enlightenment, the principal sent a teacher to send Ruomi home, but Zhongsheng disappeared until he was found on the morning of the 16th. ”

"In other words, Zhong Sheng's death is likely to be related to this missing female student?" Lin Mu looked at the information in his hand, could the deceased be retaliated against. "Did Forensic Doctor Zhen find anything?"

Zhen Zheng, who was still thinking, was taken aback by the sudden roll call: "Yes, the deceased was slashed in the neck from behind and died of excessive blood loss, judging from the wound marks, the murderer should be a left-hander." ”

"Left-handed?" Since there are obvious characteristics, the scope of the investigation can also be narrowed.

"Well, the deceased's wound was in the direction of right to left, and the wound on the right was deeper and wider, a man who used to use his left hand. As soon as Zhen Zheng's words came out, Lin Mu proposed to go to the school to check again.

Looking at the two female teachers and the principal sitting in front of him, Lin Mu began to ask after a simple politeness.

"Excuse me, are all the people here that night?"

"Not exactly," the principal said as he handed Lin Mu a glass of water, "Strictly speaking, Mr. Zhong's wife and Ruomei haven't arrived. ”

Lin Mu took the water glass and observed the movements of the principal's hand, "The Ruomei you said, can you tell us more about her situation?"

"I know that you need it, and the file has been prepared for you. The principal nodded and smiled, and motioned for one of the female teachers to bring the materials over and hand them to Lin Mu.

"Thank you. Lin Mu took it and looked at the information with Zheng Wei, "It turns out that her name is Li Ruomei, a transfer student?"

"Yes, she ......" The principal stopped talking a little, looked at the two female teachers to the side, and then looked at Lin Mu, "We only found out about this that night, and she also has a sister." Oops, "The principal pretended to be embarrassed and frowned," is one of the female students you found on the discs, who dropped out of school before. ”

"Why, aren't the two sisters together?" "Since my sister is studying in this high school, why is my sister changing schools?"

"Well, their family is complicated, their parents divorced, one of them had a child, Li Ruomei followed her mother, but I heard that the two sisters have a good relationship. One of the female teachers explained, pushing her glasses on the bridge of her nose with her hand.

It seems that Li Ruomei is indeed very suspicious, otherwise how could she suddenly disappear when Zhong Sheng was killed.

"How tall is she?" Although there is clear data in the data, Lin Mu still needs to confirm whether it is possible for Li Ruomei to cut her neck from Zhong Sheng's back in reality.

"Probably as tall as me, this kid is quite tall. The headmaster stood up and gestured with his hand.

"Well, do you know that Li Ruomei is usually used to writing with that hand?"

The two female teachers were in a fog when they heard it, thought about it, and said hesitantly, "Aren't they all right-handed?"

"Okay, I'm sorry for you. Lin Mu got up and left, walking out of the office building, Zheng Wei was a little confused, "What should we do next?"

"Go to Zhong Sheng's house. ”

Zhong Sheng's home is very simple, but it is very clean and bright, and it can be seen that his wife runs this home very carefully.

Will such a woman who loves her family see what her husband has done and hate him so much that she kills him.

Zhong Sheng's wife obviously cried, but she still didn't want to mention Zhong Sheng with a cold face.

"I'm sorry to bother you, but we came to ask if your husband has ever had a grudge other than at school?"

"Nope. He doesn't go home every day, isn't he tired of being in school?" Zhong Sheng's wife said coldly, pulling the sofa cushion very awkwardly.

It seems that I really can't accept this blow, I don't even want to mention it, and the words are full of ridicule. Lin Mu thought to himself, and then spoke, "Your husband hasn't appeared since that night?"

"Is he embarrassed to show up?" Zhong Sheng's wife snorted coldly, "After doing that kind of thing, what kind of skin does he have to go home, he is not disgusting, I am disgusting!"

She turned her head to Lin Mu and said, "Actually, you should also understand, he may have been retaliated against by that girl, but he deserves it, according to me, you really don't need to check, we don't care." With that, she turned away and stopped squeaking.

Lin Mu and Zheng Wei glanced at each other, walked away with interest, and at the staircase, met Zhong Mi who was coming home from school.

"Hello, are you Zhong Mi?" Zhong Mi heard the greeting, stopped and nodded.

"Can you have a chat?" Lin Mu asked Zhong Mi's opinion, Zhong Mi didn't answer, and moved his steps as a tacit acquiescence. He walked out of the stairs, stopped at the top of the stairs, lowered his head, and asked, "Is my dad really Wakami killed?"

"It's not certain yet. In fact, Lin Mu was not completely sure that Li Ruomei was the murderer.

"Now it seems that Wakami and my friendship will not be using me to get close to my father. ”

Lin Mu didn't speak, if Li Ruomei really retaliated against Zhong Sheng, it was also possible.

"That day, my dad actually called me and he told me not to worry, Uncle Principal would help him with it. ”

"When?" as if grasping a key message, "The principal and your dad have a good relationship?"

"I don't know," Zhong Mi shook her head, "in school, the two of them don't do very well, but that's what Dad told me." ”

Since the relationship is not very good, what can you say to help him get it done? Lin Mu felt that the principal might be hiding something from him, but it was getting late, so he had to visit again tomorrow.

"Thank you, you go home first, your mother is still waiting for you. Lin Mu motioned Zhong Mi to go upstairs first, and after seeing her go home obediently, Lin Mu and Zheng Wei also rushed back to the police station.

The next day, there were a few more reporters in the principal's office asking questions about the principal, and Lin Mu could only watch from a distance as the principal desperately defended the school's reputation in the crowd of reporters.

That's right, it's hot news that something like this happened in a high school, but these reporters are too much, Lin Mu looked at the principal's increasingly impatient face, and couldn't help but sigh a little, it's not easy to be a principal.

By the time the reporters left one after another, Lin Mu and Zheng Wei had already been squeezed out of the door, Lin Mu looked up at the principal casually, he was now acting quite angry, and he was so angry that he picked up the teacup and poured water on it.

After the last reporter went out, Lin Mu didn't enter the door for a long time, Zheng Wei was next to him and didn't know why, he stretched out his hand and shook it in front of Lin Mu's eyes, "Team Lin?"

"He just ......" Before he could say anything, the headmaster saw the two people outside the door, and he barely managed to squeeze out a little smile and greeted, "Is there anything wrong with the two police officers? ”

Lin Mu pulled back his thoughts and walked in, the principal was busy taking the water and handed over two cups, he took one of them and asked, "We didn't have anything else to do, we just wanted to ask if you and Zhong Sheng have a good relationship?"

"We're all colleagues, so the relationship is average. The headmaster turned to tidy up the table and complained, "These reporters don't care about anything, they're annoyed." ”

After saying that, the principal walked to the cabinet, opened the door, and put the materials inside.

"I'm sorry for both of you. The principal smiled embarrassedly, and a female teacher hurriedly came in outside the door, "Principal, someone is looking for you." ”

"Look, this ......" The principal looked at them with some embarrassment, and Lin Mu had to stop for a while and made a gesture of please, "You are busy." ”

Walking out of the school, Zheng Wei caught up with Lin Mu's footsteps and looked at his face, "Team Lin, are you suspicious of the principal?"

"A little. ”

"But the schoolgirl is more suspicious?"

Lin Mu stopped and explained to Zheng Wei, "I also know, but Ruomei's life and death are uncertain now, and she can't find her whereabouts. It always felt like something wasn't right. He patted Zheng Wei on the shoulder, "Let's go to the crime scene again." ”

The place where Zhong Sheng was killed was in a very old residential area, and there were few people around, most of whom were waiting to be demolished, so it seemed that this was indeed the best place to hide.

Lin Mu and Zheng Wei visited the surrounding supermarkets and restaurants, and no matter how much Zhong Sheng hid, he had to solve the problem of life. Unfortunately, there are no shops here to install surveillance.

When they returned to the alley, a black sedan parked not far from the alley caught his attention. Lin Mu walked over, and a layer of dust had accumulated on the car.

There was a small flickering red dot in the car, Lin Mu reacted that it was a dash cam, and he immediately called Bai Lan to report the license plate number, so that she could find the owner of the car so that she could get the record information.

After a period of tossing, Lin Mu was already watching the video with everyone in the police station. In the video, when Zhong Sheng was about to enter the alley, he was obviously pulling with a person.

The video is paused and then zoomed in, and the man's face is faintly visible through the faint street lights at the entrance of the alley.

"Guys, I have a discovery. Bai Lan stuck her head out from behind the computer screen and said solemnly, "Before Zhong Sheng died, in addition to his daughter's phone, there was also a phone call, and the talk lasted two minutes and thirty-six seconds. ”

Contacting various clues, Lin Mu immediately got up and applied for a search warrant, preparing to arrest the murderer.
