traces of all things

Municipal Public Security Bureau, Office of Anti-Pornography and Anti-illegal Affairs.

Lu Zheng was sitting on a chair beside him, silently watching the hard-working criminal policeman with an indescribable expression.

The criminal policeman has dark circles under his eyes and seems to be in a bad state of mind. He is still holding his eyes open and looking at the computer screen in front of him. On the computer screen, two white mosaic objects are rolling around, making a sound that makes people blush and heartbeat. .

"That's nothing." The criminal policeman took out the CD with a cold face, put a label on it and put it on a stack of CD cases, which was already a meter high.

"Xiao Zhang has just stayed here for three months." Xue Yiwei also seemed very concerned: "It already looks like this. Xiao Zhu, who worked in the anti-pornography office before him, has applied for a change of team. He said that immediately I'm about to get married, and I found myself busy at work, so I hurried to the hospital..."

This job is really sympathetic, and Lu Zheng silently shed tears of bitterness for them.

What is being intensively processed now is Mag's inventory. He is simply a huge database of all kinds of prohibited movies. It's been two days.

During the chat with Jia Kaijie before, Lu Zheng had doubts about the behavior of Jiang Pengyun's children, but after all, these children are only elementary school students, and frequently summoning them to the police station is not good for their growth, Lu Zheng I had no choice but to insinuate, trying to dig out some of the relationship between Ma Ge and those students, especially Jiang Pengyun.

In any case, there must be some reason for trying to blame someone, right?

There is no direct relationship between Jiang Pengyun and Jia Kaijie, and their families seem to have never been in contact with each other before, and they are not even from the same village.

Could it be that the suspect in white and black trousers had some kind of relationship with Jiang Pengyun, so in order to cover him, Jiang Pengyun chose to give false testimony and wanted to blame Mag?

Boss Geng and the others organized a team of investigators to investigate Jiang Pengyun's relatives and friends after listening to Lu Zheng's analysis, while Lu Zheng and the others tried to make some breakthroughs from Mag himself.

Mag’s films were messy and poorly organized, and some of them were sold as sheep’s clothing. When I entered the computer, the computer screen was completely black for an instant, and then only heard a few "creaking" sounds, and the screen suddenly lit up, and several bloody heads jumped out with a "snap", with long tongues sticking out.

"Damn—!" Poor Wei Xiongfeng howled, frightened half to death by this terrifying scene.

Xiao Zhang, the criminal policeman, was not surprised and was unmoved. He speeded up the playback quite calmly, and saw a group of demons dancing on the screen, and various human internal organs flying around. The scene was extremely uncomfortable. Finally, a person like a Maoshan Taoist stood up He came out, brandished a wooden sword, and nailed a ghost with a long tongue to the wall, then took out a handful of unknown soil from his bag, mixed it with water, and moved his finger, the lump of mud "cracked" ——" a sound was stuck on the female ghost's face.

The female ghost let out a terrifying roar, then fell to the ground and did not move, and soon disappeared into a pool of ashes.

Lu Zheng's heart also twitched a few times, and he quickly got up and stepped forward.

"Xiao Zhang, what is the title of this film? Are there many people watching it?"

What was confiscated at the same time, in addition to various colorful small films, bloody and violent films, and a small ledger found by the police at Mag's house, recorded some of Mag's transactions of renting books and discs. Records, this is also one of the main evidence for the specific punishment for Mag.

"This movie is called Nightmare." Xiao Zhang turned the DVD cover over, and read it from the dog crawling on the small note pasted on it for a while, and then searched for a while in the small ledger: "All Here, hey, there seems to be quite a lot of people watching this piece of shit.”

Lu Zheng took the small ledger and read it carefully. Before he could find the record of renting "The Nightmare", he found a familiar name.

"Jiang Pengyun - casino situation - two yuan."

"Jiang Pengyun - Young and Dangerous - Sanyuan"

……

It seems that this student named Jiang Pengyun really has some intersection with Ma Ge!

Was it because you came to Mag's house to watch the video tape, so you had some grievances and conflicts with Mag?

However, Lu Zheng searched the entire ledger, but he couldn't find the record that Jiang Pengyun had watched "The Nightmare". Jiang Pengyun didn't seem to be interested in this type of film. Movies with similar themes, and two sporadic movies that are unsuitable for children just by looking at their names.

Lu Zheng frowned, and suddenly had an idea, turned back to the front page of the ledger, and searched one by one again.

When his fingers slid over the last few pages of records, he suddenly made a new discovery.

"Luan Kang - The Nightmare - One Yuan"

Luan Kang, Jiang Pengyun's little follower, once watched a movie that included elements of wet muddy faces.

Jiang Pengyun and his two followers were at the scene on the night of the crime.

When Jia Kaijie stood on the mountainside to help them watch the wind, there were only Jiang Pengyun and other three students on the top of the mountain, and Teacher Jiang who was knocked out.

Could it be that it had nothing to do with the man in white and black trousers, and that it was Jiang Pengyun, Luan Kang, and Shan Jianming who did all this?

But the oldest among them is only 12 years old? !

Even if he hated the teacher, would he hate it to the point of killing him?

Or, the man in white and black pants is the mastermind, and these children watched the scene?

It was clearly only the beginning of autumn, but Lu Zheng felt a gust of wind blowing through his heart, and he became cold from head to toe.

**

A conjecture is just a conjecture after all, and Lu Zheng doesn't have any evidence to prove this crazy conjecture, so he has to try to dig again from other angles to see if he can find some missing evidence to form a chain of evidence.

The day passed with no results.

Early the next morning, Lu Zheng rushed back to the physical evidence center of the Municipal Bureau, and met Wei Xiongfeng who was sneezing outside the office.

"What's the matter, Nobita?" He asked concerned, "Have you caught a cold?"

"A little bit." Wei Xiongfeng looked a little sluggish: "Recently, I have worked too much overtime, and my resistance seems to be a little low-hey, today just happened to be cooling down."

One autumn rain and one cold, last night it rained patteringly all night, the temperature in the provincial capital suddenly dropped today, the streets were full of rain and fallen leaves, it looked very bleak, it felt a bit late autumn.

While talking, Wei Xiongfeng shook off a crumpled piece of fabric in his hand: "Fortunately, when I went out in the morning, my mother reminded me to take a sweater. Um - it's warm."

He pulled a furry, rumpled dress over his head in threes and fives, the sweater stuck subtly for a moment as it passed his round head, but he ripped it off rather violently.

This sweater was made by Wei Xiongfeng from some corner. The dark blue surface is full of wrinkles, and there are a lot of fine hairs that don't know where it came from.

Looks like a dick.

"Nobita, your sweater should be washed and ironed." Lu Zheng saw Tang Shaoyuan, who was used to being well-dressed, and felt that it hurt his eyes at this moment.

Wei Xiongfeng looked down at his sweater, and he didn't seem to think there was any problem with wearing it like this: "Leader, there's nothing you can do about it, the sweaters are all sticky, especially the dark ones, and it's useless to wash them, depending on your habits. Enough."

He was justifying, but before he finished speaking, Tang Shaoyuan came in at the door.

Four eyes facing each other.

"Pfft-"

It was Lu Zheng who laughed. Tang Shaoyuan, who was standing at the door, also put on a sweater over his shirt in accordance with the season. It was black and darker than Wei Xiongfeng's, but the whole sweater was clean and smooth. There is no trace of wrinkle, and the black is deep and classy, ​​not to mention the little fluff sticking to it.

The contrast is too obvious.

Being slapped in the face in public, Wei Xiongfeng's face flushed instantly.

Just when he was about to dig a hole in the ground, Lu Zheng suddenly stopped laughing, and stared at the sweater on his body with a strange and bewildered look.

"Sweater...sweater...yes, sweater!"

After muttering a few words to himself, Lu Zheng stood up quickly and walked into the evidence storage room next to him.

Seeing this, Tang Shaoyuan followed in without saying a word.

Only Monk Zhang Er was left puzzled by Wei Xiongfeng, who was still pulling on his sweater, studying what Lu Zheng had just seen.

**

The evidence storage room of the Municipal Public Security Bureau.

"Brother, what did you think of just now?" Tang Shaoyuan walked into the storage room, put on a white coat and sat down beside Lu Zheng, and asked in a curious tone.

On the other hand, Lu Zheng quickly found a storage box marked with the label of "jacket", put on his gloves carefully, took out the contents, and said, "I just looked at Nobita's sweater and remembered that he and I said that sweaters are easy to stick to wool, and I suddenly recalled that the victim was also wearing a woolen cardigan."

"So I thought—" Lu Zheng spread the dirty cardigan on the laboratory table, and took out a large roll of scotch tape from the toolbox: "Have you heard of Locard's law of material exchange? Shao Yuan? "

Tang Shaoyuan is a top student who graduated from a major, of course he knows this law fluently: "Whenever two objects touch, there will be a transfer phenomenon..."

Speaking of this, he seemed to have some epiphanies.

"That's right, as long as the murderer has contact with Teacher Jiang's body, he will definitely leave traces of physical evidence." Lu Zheng said: "Ms. Jiang lost the ability to act independently after being knocked out, so she can't possibly Drag yourself into the grass by yourself?"

Tang Shaoyuan looked at the two shoulders of the dress, and suddenly his eyes lit up: "Brother, you mean..."

Lu Zheng took off his gloves and walked behind him, two arms passed under his arms, as if embracing him from behind, he hugged most of his body and pushed back slightly.

"Do you feel it?"

When he spoke, his chest was still shaking slightly, and goose bumps appeared on the back of the person clinging to him for a moment.

Tang Shaoyuan: ...

It feels great.
