Special case investigation team V

Later, Li Hui took the poisonous needle report mentioned earlier and showed it to Cheng Jin.

Ordinary needle tubes, equipped with dart-like tails, are fired with crossbows, with an effective range of 50 meters.Once the target is shot, the anesthetic and cyanide in the needle will be injected into the target immediately.The effect is outstanding, if the skin is scratched, it will be put down, if it is tied firmly, it will not only be put down, but will be fatal.

It is difficult to buy this poisonous needle in physical stores, but it is not difficult to buy it online.

Of course, most people will not use it on humans after buying it, but mainly use it to prick animals, and then sell it to people who like it for food, so as to make a profit. ——Animals that are poisoned to death are actually poisonous, and human consumption is harmful to the body.

Cheng Jin handed over the report to Han Bin.

Han Bin flipped through the pages, smiled in a good mood, and said, "Targeted toxicology tests will be done faster."

There are too many poisonous chemical substances. If there is no suspected target, then the toxicology test in this case is like finding a needle in a haystack, because the corresponding symptoms of poisoning cannot be discerned from the body parts.It's like you only have a vague impression of a word, and you can't look it up in the dictionary according to the index. You can only flip through the dictionary page by page, eliminating each word, and you don't need to think about it.This is the case when it was not detected whether the victim was poisoned before.

Targeted toxicological testing is equivalent to narrowing the scope of suspicion.Toxic chemicals will produce some new things after entering the human body. Just compare the poisoned human body samples with the results that should be produced after the suspected chemical substance enters the human body, and you can know whether the two are the same chemical substance, or what is the probability of it being the same chemical substance? same kind.

Cheng Jin said: "It doesn't have to be this."

However, there were no fatal wounds on the corpse, and the possibility of poisoning was very high. It was necessary to do a toxicology test, even if it was for nothing, it had to be tried.

"I'm going to the laboratory. Don't call me when you go back to the hotel." Han Bin rolled up the report, put on his backpack, and left.

Cheng Jin looked at the time, it was getting late, "Go back to sleep if you have nothing to do."

Nobody moved.

Cheng Jin didn't say anything more.

After tens of minutes, Xiao An suddenly shouted: "Boss, I found something useful!"

Everyone was taken aback.

You Duo was right next to Xiao An, and he leaned over to have a look.Xiao An chuckled, "Look, I've found the right direction." You Duo didn't say anything.

Bu Huan yawned big, "Girl, you've scared me out of drowsiness."

"What?" Cheng Jin wanted to stand up, but Yang Simi was leaning against him, so he hugged Yang Simi and let him lean on the chair.Yang Simi's eyelashes trembled, and she looked at Cheng Jin as if she was sleeping but not sleeping.Cheng Jin smiled, stroked Yang Simi's hair again, and walked away.

"What?" Cheng Jin walked behind Xiao An.

"I found this in Du Qian's computer." Xiaoan enlarged a photo and spread it on the computer screen.

"What's wrong with Du Qianhuai? Is he really suspicious?" Ye Lai just came over, and when he saw it, he gasped.

The photo is a staged still life, but the material is very weird.The subject is a male head and two severed arms. They are placed on a cushion made of green branches. Below the branches is a bare rock-like ground. The background of the photo is a hazy green with excessive blur, and the original environment cannot be seen .

The head and severed arm looked fresh, as did the green branches underneath, which looked familiar.

Cheng Jin said: "The protective forest."

"Yes." You Duo said.

That branch is the branch of a tree like the shelter forest, and this photo was taken in the shelter forest.

"Destroy the environment." You Duo said again.

"That's right, it's not easy for that tree to grow up. Who dares to break it." Bu Huan rubbed his chin and said, "But this photo is quite plausible. Is it real, or has it been processed?"

Cheng Jin said: "This head belongs to Dong Shaokang."

"Yes." You Duo also remembered.

Before, a couple disappeared near Yunshu, and the male one was Dong Shaokang.

Bu Huan was stunned for a moment, "So, have we found the murderer?" So suddenly?

Cheng Jin said: "Simi, come and have a look."

Yang Simi raised his eyelids and looked at him, then put his hands on the chair, stood up, walked around the desk, walked to Cheng Jin's side in a few steps, and at the same time glanced at the photo out of the corner of his eye, um, what?He looked at it squarely, then raised the corner of his mouth, "Interesting."

He looked at it for a moment and said, "This angle for taking pictures is not the best."

"..." Everyone was thinking, in terms of toughness, no one could ever compare to Teacher Yang.

Cheng Jin treated Yang Simi's words very rationally, he said: "The person who took the picture and the person who arranged the scene are not the same person?"

Yang Simi winked at him, "The lighting is not right either. This photo can be more perfect."

Cheng Jin looked at him helplessly.

Yang Simi looked back at the photo, "Is this the original picture? When was it taken?"

Xiao An checked it, and it was the original image exported from the camera. The photo information recorded the shooting time, and the deceased died on the day of his disappearance.

Ye Lai said: "It turns out that they were taken to the Gobi at that time."

Dong Shaokang and his girlfriend disappeared on the highway. The police speculated that the car broke down and they hitch a ride with someone else. Unfortunately, the surveillance on the highway did not capture the suspicious vehicle.Yuan Ether's car didn't take the road at all, and drove directly to the Gobi, so it couldn't be photographed.

"Poor." Bu Huan said, "I hoped that their disappearance had nothing to do with these dismemberment cases. Is that woman dead too?"

No one responded to him.

"Is there anything else?" Yang Simi asked Xiao An.

"No more, just this one. He specially encrypted it."

If it is not encrypted, Xiao An may not be able to see it. After all, he suspects that there are so many photos in the computer. Find out what it is.

Yang Simi looked at the photo again, "There must be a series."

Ye Lai sighed: "So many people died, it's enough to shoot a series."

Xiao An said, "Then I'll look for it again." He pulled La Youduo's sleeve again, "Come and help."

You Duo nodded, "Okay."

Xiaoan hacked into Du Qianhuai's computer secretly, and he didn't hide it from You Duo, and You Duo was sitting next to him.You Duo didn't say anything when he saw it, he didn't support it or object - Xiaoan didn't understand it as acquiescence, she thought You Duo was silently opposing it.But now, You Duo has to support her.

Bu Huan sent the photo to Han Bin.

Han Bin also recognized who the deceased in the photo was, and replied: Dong Shaokang is dead?How about Holly?

Hou Li is Dong Shaokang's girlfriend, and the two of them disappeared together.

Bu Huan: Still missing.

In fact, Dong Shaokang's whereabouts are still unknown. We have to look for him in the shelter forest tomorrow, and I don't know if we can find him.

Xiao An and You Duo searched Du Qianhuai's computer upside down, but they still couldn't find the so-called series of photos.

"Strange, why is there only this one? Even if there is only this one scene, he can take more than one, right?" Xiao An wondered.

Cheng Jin said: "He may just be an eyewitness, happened to see this scene, took a photo, and then he ran away."

"Why didn't he call the police? He is a government servant, so logically he should not be afraid of contacting the police." Ye Lai said.

"Maybe he did something wrong?" Xiao An frowned, "Oh, who cares why, let's catch him and talk about it later!"

Bu Huan looked at Cheng Jin, "Go and bring him back now? Interrogate him overnight?"

Cheng Jin said: "Call Captain Li over to discuss it first."

"Row."

Li Hui came over, was shocked when he saw the photo, and then insisted that Du Qianhuai should be taken back immediately.

Cheng Jin also agreed.

Li Hui went to arrest people in a hurry.

After he was arrested, he was interrogated overnight.

Du Qianhuai said that he didn't kill the man, and when he got there, the corpse was laid out like that.

Asked that he only saw a head and two arms, but did not see other parts of the body?

He said yes, but he also said that he didn't take a closer look, took a photo and ran away.

Ask him why he didn't call the police.

He said he was terrified.

Not everyone believes this statement.

Later, he simply gave him a polygraph test, and the result really ruled out his murder suspicion. ——The polygraph results cannot be used as evidence, and are generally used to exclude suspects as criminal suspects.

After the polygraph test was done, Cheng Jin and Yang Simi went to see Du Qianhuai.

Du Qian said anxiously: "Didn't I pass it? Can't I leave?"

Yang Simi threw the polygraph data map on the table, "Do you understand?"

They all kept silent.

Cheng Jin put the photos of Dong Shaokang and Hou Li on the desktop, "This young couple is 20 and 19, young?"

All said modestly, "I didn't kill them."

"They? Where's the girl?"

"……I have no idea."

Cheng Jin tapped the polygraph data map, "You know."

Yang Simi made up the knife next to him, "Unless you are anti-social, you won't be able to fool a lie detector." He said with a half-smile, "If you are really anti-social, then you will be in big trouble. You know what it means to be anti-social." What are you wearing?"

"..." Du Qianhuai's face was very ugly, his fingers twitched, and he looked very nervous.

Yang Simi smiled and said, "Let's talk, be calm, the more you dodge, the more suspicious you will be."

The more he smiled, the more nervous he became, shaking like a pendulum.

Cheng Jin comforted, "As long as you are not the mastermind, it will be in your interest to take the initiative to confess the facts."

Du Qianhuai was very anxious, and stumbled: "No, no! I didn't plot anything, neither the mastermind nor the accomplice! I really didn't kill anyone, I just saw that girl..."

That afternoon, Du Qianhuai went to the Gobi to take pictures of the scenery, and then met a girl in the wilderness, and that girl was Hou Li in the photo.Hou Li stopped his car in a panic, wanting to take a ride.They all agreed humbly, and everything was normal at first, but when he saw that Hou Li was wearing very little, only a dress with a wide open neckline and a short hem, he started to think carefully and touched tentatively. After grabbing Hou Li's thigh, Hou Li went crazy...

Cheng Jin said, "You hit her?"

"I didn't want to either, it was her who made the first move, she was crazy..."

Hou Li had just escaped from the tiger's mouth at that time, thinking that she had entered the wolf's den again, she must have been frightened crazy.

That day, she and her boyfriend were driving out of the city, and the car broke down in a place where nothing shit happened. After calling for a long time, no one came to rescue.Later, when they saw that a car finally came, they decided to take that man's car and go back to the city first.

After getting in the car, she and her boyfriend drank each other's water and fainted.When she woke up, she found that she was alone in the car, her long coat was missing, and her boyfriend was not in the car, so she opened the door and got out of the car, and then saw a horrified scene: her boyfriend was lying on the ground , someone next to her was sawing her boyfriend's leg with a saw.

She screamed and then ran wildly. The man didn't chase her, probably thinking that it was deep in the Gobi and she couldn't get out.

She couldn't walk out with her feet, but later, she met Qian Huai.

Du Qianhuai was driving alone, and he was a man. Before getting into the car, Hou Li was actually very afraid of him, fearing that he would be with the man who saw her boyfriend, but she was lucky and wanted to get there first. Let's talk about the place where there are many people, but they all touched her in the middle of their arms, and the string in her mind was finally broken. It really is a group...

Cheng Jin said: "Then you left her?"

"She opened the car door and ran away by herself, I can't help it...she is really crazy..." Du Qianhua lowered his head, his voice became smaller and smaller.

At that time, Du Qianhuai thought it was nothing, the girl ran away, anyway, he didn't do any real...things.He saw that the time was still early, so he continued to drive forward, taking pictures all the way, and later saw Dong Shaokang's body in the protective forest. He was attracted by that scene as if possessed, took a photo, and then reacted It was a dead man, he staggered back, then turned and fled...

Later, the more he thought about the whole day, the more he felt something was wrong, and he didn't dare to call the police for fear of being involved in some big case.After returning, he continued to work and live as usual, but he didn't dare to go out to wander around anymore, and stayed at home every day to watch TV and surf the Internet.Until Ye Lai noticed him, and Xiao An hacked into his computer.
