Chapter 318: Biological Samples

After reading the book, the address of [Wanbenshen Station]: Avoid the pain of chasing books!

The classroom of the second and third classes of high school is the first room at the left end of the third floor, and on the way between Ning Zhi and Ning Yuan, almost every classroom has a probe or a student lying on the observation position of the head teacher.

Such a terrible thing happened in the school, and everyone was terrified. Even the sound of the text being read aloud in a group is full of empty tones.

The classrooms of Class 3 were empty, and a blue and white cordon was drawn outside the door. The two looked inside and found that there was not much difference between the inside and the day of the crime, the tables and chairs were left in place, but the students were gone.

One is to protect the crime scene, and the other is to avoid the school. The students of Class 3 were temporarily moved to another vacant classroom.

Without more than a dozen people, the originally crowded classroom suddenly became empty. Sunlight poured in through the windows, and a few clouds of dust lit up, making the entire classroom look dusty.

The two of them put on their feet and gloves at the door, and they came here today to investigate the scene again. Now there is only solid evidence that can make Director Li speak. Obviously, he is the type who doesn't shed tears when he doesn't see the coffin.

Some of the footprints next to Lin Chaolu's seat and even in the aisle were collected by the electrostatic adsorber, and the ones left in place were even more chaotic.

There was also copper powder on the table that had been accidentally left behind when fingerprints were taken.

The rest of the belongings were packed into evidence bags and brought back to the detachment. This includes a glass for her to drink from, and a pill box for her pills.

Footprints are worthless.

Fingerprints are for yourself and your friends.

The key is the surveillance video, which realistically records the scene of her suicide.

Ning Yuan was looking forward to finding a biological sample that might be related, but after squatting for a long time, he was a little dizzy the moment he stood up, but he still didn't find anything new.

Although he already had a 90% chance in his heart, it was clear that Director Li was not the direct cause of Lin Chaolu's death.

However, the scene of the crime has the most information, and if something can be found, it may be of great help to break through Director Li's confession.

But no.

"Brother, where are you?" Ning Yuan pinned his hopes on the other side.

Ning Zhi stood up and shook his head.

"I don't know if Fang Ye found anything in the dormitory? Like you, he is from a trace detection background, and he has been following you out on the field, maybe he can find new clues by checking the dormitory again. ”

"The things related to her in the dormitory have basically been brought back to the detachment, and the bathroom has also been checked, but unfortunately after a long time, Lin Chaolu has washed it frequently, so we have investigated several times and have not found any clues."

Ning Zhi reluctantly said this, not wanting to draw that conclusion. In other words, it was Lin Chao who showed the fear and shame of being discovered by others, so little by little, he destroyed all the evidence with his own hands.

While the two were talking, Fang Ye also came up. When asked about the dormitory, he shook his head and didn't say much.

"Since physical evidence cannot be counted on, I have to rely on human evidence."

Ning Zhi waved at the two, and his tone was a little lonely.

As Ning Yuan said, he was originally from a trace examination, and it was really helpless to encounter this situation.

The place where Class 3 was temporarily moved was a classroom on the right side of the first floor.

The three of them went downstairs and just walked over, just in time to see Chen Xi covering half of his face to open the door of the classroom.

The door was ajar, and most of the classroom was visible. Ning Yuan just probed the probe and found that everyone was pointing at Chen Xi. Seeing that they were also there, they lowered their heads again.

"I'm really sorry that I need to cooperate with the recent inquiries and disturb your normal class." Ning Yuan opened his mouth in a low voice, and then pointed to the corridor and asked if she could come out to speak.

"What's wrong with your face?" Considering that it was a girl, Ning Yuan didn't dare to pull it directly. Chen Xi let go of his hand and slowly brushed his hair away.

Four scars of different lengths were across the left side of Chen Xi's face. Most of the skin was broken, and in a more serious way, it had begun to bleed.

A girl, if she has a scar on her face, is really not a trivial matter. Ning Yuan didn't dare to ask again, and motioned for her to go to the infirmary to deal with it first.

Xu Yang came out of the bathroom on the other side and happened to collide with Chen Xi, who was going out with his face covered. With his intuition, he already knew he had made a mistake.

"Team Ning, I was wrong." Xu Yang came over with a sad face, and secretly poked and poked Ning Yuan's sleeve, the meaning of asking for help was very obvious.

"Yes, you're done. The compensatory time off is gone, the subsidy is gone, and I have to continue to work overtime. Fang Ye followed Ning Zhi for about two years, and every time he did something wrong, he would be scolded or stared at by death. Now facing the little auxiliary policeman, I immediately feel that I am a turned serf and sing.

Ning Zhi was in a very bad mood and didn't want to talk nonsense with them, so he just signaled Xu Yang to explain quickly.

"Everything was fine before I went to the bathroom, and Chen Xi went back to the classroom for class. Then Aunt Lin came, I guessed she was going to make trouble with Director Li, so she found time to walk away for a while, who knew this kind of thing would happen. ”

Xu Yang finished speaking aggrievedly, pointed to his face again, Ning Yuan nodded, and everyone was silent.

After waiting for a while, Chen Xi came back again. She was followed by the teacher in the infirmary. When the teacher saw them, his face was a little sneering. She was still blaming herself for providing Lin Chaolu with sleeping pills, and her gaze was sometimes evasive.

"There is a high probability that the injury on her face will leave a scar, please persuade her to go to the hospital in time to deal with it." Ning Yuan couldn't help but step forward, and the teacher nodded hurriedly, in comparison, Chen Xi himself seemed to be the one who didn't care the least.

"Aunt Lin beat it?" Ning Zhi asked.

Chen Xi didn't speak, just nodded.

"Why did she do that?" Ning Zhi asked again.

This time, Chen Xi never said again, and he refused to cooperate.

Her face had just been injured, and Ning Zhi was just asking, not being unkind.

Seeing that they couldn't ask anything, several people walked out together.

Xu Yang was left on the first floor waiting to make up for it, while the rest of the people walked out of the foyer.

The teaching building of the second year of high school is at the front of the square, near the window on the first floor, and there are many acacia trees.

When Ning Yuan was still in school, these trees were already there, and no one knew how many years they were.

This season, there is no flowering. However, Ning Yuan passed by, and was still reminded of some memories, and stood in place and smiled.

Ning Zhi sneezed and walked a few steps quickly, far away from the trees.

"What's wrong?" Fang Ye was a little baffled by the brothers.

"It's okay, it's just remembering some things from school." Ning Yuan hurriedly clicked over and went to chase his brother.

Chen Xi was standing in the hall on the first floor, and when he saw that they were all far away, he walked to the right.

The second room on the right is the collective office of the sophomore class teachers.

There are six desks inside.

Chen Xi is also used to the nervousness and fullness of every time he comes here.

However, now there is no one but Mr. Wen, and the lesson plans and workbooks next to the monitor are still crooked.

"Lin Chaolu's mother came here just now."

Teacher Wen explained to her that she saw that she had gauze on her face, so she didn't dare to ask more, so she excused herself to pour water and turned to leave.

Mother Lin is making more and more trouble at school, especially in this office. Many teachers are overwhelmed and are even more afraid of causing trouble, so many times, they go to other teaching and research departments to hide.

Teacher Wen soon came back and handed her a disposable water glass. Chen Xi took it, but put it aside, walked to the door, closed the door again, and locked it again.

"Teacher Wen, I have something I want to say to you."

Chen Xi didn't give her time to react, and went straight to the point, "About Director Li, you get along with him day and night every day, you should know something." ”

"What are you talking about?" Teacher Wen felt that her nerves, which had been slightly relaxed, were picked up again, and she drank the water she had poured for others, and then realized her gaffe.

"Chen Xi, do you know something? You ran to the rooftop that day, and then at the police station, obviously you had something to say, didn't you? ”

"I see it." Chen Xi was stunned word by word.

Teacher Wen grabbed her arm in a hurry, "What do you see?" ”

Those hands were clenched so tightly that Chen Xi could feel a clear pain through the thick clothes of early spring. Mr. Wen's eyes were wide open, as if they were about to pop out, a bit like a dying goldfish after being caught.

Chen Xi suddenly felt a little frightened, turned his head away, and didn't dare to look at her.

"One night during self-study, I went to the bathroom with an upset stomach, and when I came back, I happened to bump into Lin Chaolu, who ran out of the political and religious office in a panic, and didn't even know that she had bumped into me. The next day I asked her what was going on, and she told me that you were the ones who asked her to help put together some information. ”

"I believed what she said at the time, and now that I think about it, how could it be possible, until" Chen Xi stopped, bit his lip and stopped talking.

"Until what? What else do you know? ”

Teacher Wen grabbed her tighter, making the two get closer. She didn't care about her demeanor at all, and she didn't know how terrible the expression on her face was.

"Lin Chaolu is dead, she's dead."

"I was killed by Director Li, and the body is still in the morgue of the detachment, which is very dark and cold."

Chen Xi couldn't bear it anymore and finally broke out. She pushed the person away with all her might, and all of a sudden, both of them were stunned.

"I also sympathize with Asaka's plight, but I don't know about it, and I can't do anything about it." After being stunned for a while, Mr. Wen found his voice back.

There are shadows passing by in a hurry outside the window, and they are students who come to see the excitement after class.

"You don't have to know, just bring this thing." As he spoke, Chen Xi casually found a blank piece of paper and leaned over to write.

Teacher Wen leaned over and found that there were only two words on it, "Hair." ”

"What are you collecting his hair for? There is no physical evidence, and even if DNA is tested after it is obtained, there is no comparison sample. She raised her head and looked at Chen Xi.

"This teacher doesn't have to think about it, he just needs to find a few hairs with hair follicles in the bathroom at home."

Chen Xi replied in the same tone, in fact, her hands were shaking a little.

Xu Yang was just outside the window and listened to it clearly. He sent a WeChat message to Ning Zhi about the situation just now, and waited for what might happen next.
