The Underworld Detective

Wang Dali saw me with Huang Xiaotao and ignored him. He was angry. “Shit, I asked you so many questions. You ignored me. Sister Xiaotao just said one word and you said yes. Did your ears actively block my words? ”

I said, "Okay, I'll answer your questions later!” Then Huang Xiaotao said: "Fingerprints and fingerprints look similar in shape, I wonder if it's possible to kill and abandon the same person. ”

“Same person?” Huang Xiaotao provokes an eyebrow: “But a cautious one, a hasty one, would this be the same person? ”

I took my gloves off, took a cursor caliper out of my handbag and matched it with my fingerprints. The fingerprints on the bag were very blurry, I could only find three complete fingerprints, and the matching results showed that the three fingers were the same length as the fingers on the body with the sun marks!

This is strange, because the killer was calm when he killed and carefully wore gloves, but left a lot of fingerprints on the plastic surface that easily left fingerprints, and he seemed so panicked when he dumped the body.

Yellow Peach's question is exactly what I can't figure out, but I think this bug seems to be the key to everything, except that it's now like a layer of windowpaper with no puncture, and it feels like a fish prick stuck in its throat.

“Do you want to continue the test?” Huang Xiaotao asked.

“Don't bother. ”

After I said, I pulled out a piece of yellow paper, burned it, read a "curse to life", suddenly a shady wind in the bridge swept up and the paper ash disappeared on the river, many cops watched.

Huang Xiaotao seems to have become accustomed to this scene: “Song Yang, why don't you go back first, I'll stay and clean up the scene, there's nothing to investigate for now, just wait for the clues to be compiled tomorrow morning. ”

I wanted to say stay and help, but there's nothing I can do here, plus I'm really tired from 4: 00 in the morning until now, so I agree, I feel like I'm not as strong as Huang Xiaotao.

When I got back to school, the afternoon classes were, of course, skipped and I kept searching the library for information until the library closed at night before returning to the dormitory.

When I went back, I was lying in bed thinking about the case, and Wang Dali picked up on the edge of the bed and asked: "Yong Zi, you're still thinking about the case, you won't survive like this. Go to bed early. Don't you have a meeting at the police station tomorrow morning? ”

“Okay, okay, I don't want to.” I replied.

“By the way, you didn't go to the water room to get water, I got you a pot of hot water, I still have some instant noodles in my drawer, if you're hungry, eat noodles.” Wang strongly persuaded.

I was warm in my heart. Wang Dali was never so kind to me because of the prize money. In fact, he has been taking care of me since the beginning of college. When I die with something, I sleep and forget to eat. Wang Dali often fetches water and brings food for me. It's really worth it to have such a good buddy in college.

I said thank you, Wang Dali said: “That's very strange. My brother also said thank you. ”

I was lying in bed thinking about the case and didn't sleep until 3: 00 in the morning, and then I had some messy dreams, which I didn't sleep well anyway.

The next morning, Wang Dali and I came to the police station early. The police arrived. Huang Xiaotao invited everyone to breakfast as usual. I noticed that Dynasty Aid was not here. Asked Zhou. Zhou said that Dynasty Aid came out early this morning and went to Machine Fire's home to investigate the case.

At 8: 00, Huang Xiaotao pinched the spot and started the case discussion.

First, we talked about the progress of the case, and then we summarized the clues that you investigated. The rope that the killer used to tie the bag had been found to be made by a manufacturer, but the rope had dozens of points of supply and sale in Nanjiang City, and it took some time to get rid of it.

In addition, there is no hospital in Nanjiang City that uses this drug anymore, not even a pet hospital, and no manufacturer in the country is still producing it. It is a reliable assumption that the killer bought the raw materials and synthesized them.

Someone questioned whether the suspect Machine Fire, though of high school literacy, could combine laughter?

Another police officer said that now everything can be searched on the Internet, that there is a great deal of criminal knowledge in film and television dramas, that people with bad intentions can learn any criminal technique, and that there have been a few blind old farmers before, imitating homemade explosive bags from film and television dramas to rob money carriers.

Zhou explained: "Laughter is a simple inorganic substance that can be obtained by thermal decomposition of ammonium nitrate in fertilizer. Anyone with a little knowledge of chemistry can make it online. ”

Huang Xiaotao interrupted their argument and continued, mainly with some clues that I found on the body, as well as some of the information that we heard during our visit to the residence of the missing person. When it became apparent that new victims would appear in the two days, the scene was silent and perhaps everyone felt time was running out.

The case is currently glued. The whereabouts of the Machine Fire are unknown. There is no connection between the several deceased. How do we find out?

Huang Xiaotao said to pull out all the surveillance videos near the supply and selling point of the rope, today everyone stop doing anything, watch the video for clues.

Then she asked me what advice I had, and I thought, "The killer must have kidnapped someone in a car that should have appeared near the homes of the three missing persons, and it might be helpful to find a checkpoint and community surveillance. ”

“Yes!”

Huang Xiaotao immediately called several policemen and went to the Ministry of Transportation and the neighbourhood where the missing persons lived to retrieve the video.

After the meeting, Huang Xiaotao said to me: "Song Yang, the third victim has not been found yet, why don't you go back first. ”

“No, I'll watch the video with Wang Dali.” I said.

“Fine! ”

Throughout the morning, we watched surveillance videos at the police station. Huang Xiaotao asked people to move the TV and video recorder to the conference room and went to the nearby electronics mall to rent them if the equipment at the station was insufficient. Everyone took a corner and stared at the images without blinking. From time to time, someone stopped to drip eye drops or light a cigarette. The curtains were pulled in the room and the smoke was all over them. If someone suddenly walked in, they might think they had entered a video studio.

All the videos combined for thousands of hours, they were watched twice as fast. Wang Dali and I stared at a TV, and after a while, we felt bored and bored, and people were going to fall asleep.

Wang Dali finally really didn't want to see it. He paralyzed on the chair like he wasn't cute: “Too many bored, now give me a copy of" The Weeping Sheep and the Grey Wolf "and I can see it all smelling good. ”

“The police investigation is like this, and the clues to Sesame can't be let go, cheer up! ”

At my urging, he sighed and continued watching the video.

Efforts were also rewarded by the discovery by a police officer of a white van from community surveillance, which was also present at the residence of two other missing persons, and which coincided with the time of the victim's disappearance.

Huang Xiaotao immediately sent someone to the Transportation Department to check the license plate number of this car!
