Serious Crime Unit 1

Chapter 1130 Greed (23)
Jiang Yiming and Lu Yingying took Li Xiaoqing to the interrogation room and questioned him again: "Li Xiaoqing, after a polygraph test, it shows that neither you nor Guan Hua lied. This attitude is worthy of praise, but I still need you to continue to cooperate with the investigation."

"No problem, I will tell you whatever I know. I really want to atone for my sins." His expression became a little more relaxed, probably because he was praised by Jiang Yiming.

"If you think about it carefully, when did Xu Dongfang leave the cabin to collect the ransom?"

"It should be around 19 p.m. on the 9th that he carried a drone down the mountain, then rode a motorcycle to Laishan, and operated the drone to bring the ransom back to the cabin. He said he stood on a big tree in Laishan and used The telescope can observe the situation under the unfinished building. Even if the police follow Yang Lihong, they will not be able to arrest him, let alone get the ransom back, so everything is guaranteed."

"Before Xu Dongfang left you and Guan Hua, did he do anything unusual, such as asking you to eat or drink water?"

"Oh, by the way, before he left us, he took out three cans of Budweiser beer from his backpack, handed one to each of Xiaoguan and me, and told us to drink. He also drank one, and he left after drinking. Of a log cabin.”

"Did he watch you and Guan Hua finish their beers before leaving?"

"Yes."

"What happened next? Did you fall asleep?"

"Ah? How do you know? Are you a god descending to earth?" He looked at Jiang Yiming in disbelief, as if he was hiding behind the wooden house and watching.

"I'm not a god. I made the guess based on many years of criminal investigation experience. Is Guan Hua asleep?" This is very important. If Guan Hua is not asleep, it means that he may let Chen Feng go.

"He also fell asleep. It was very strange. I am a person who is very good at staying up late. I once played games in an Internet cafe for three days and three nights, and I could bear it without sleeping. I don't know why, but I only stayed up for 21 hours before going to bed. Well, in order to get 10 yuan, I am more energetic than ever because I am afraid that Chen Feng will run away. If he runs away, not only will he lose money and people, but he will also most likely be beaten up by Brother Xu, so I Use a hundred times more energy to guard Chen Feng."

"You are so stupid. You were sold by Xu Dongfang and you helped him count the money. Let me tell you, the beer Xu Dongfang gave you and Guan Hua contained anesthetics. You fell asleep immediately after drinking it."

"How is this possible? Why would Brother Xu do this?" He didn't understand very much.

"Because he wanted to let Chen Feng go and let him go to Luyin Villa to kill people. After killing the people, he returned to the cabin. After Chen Feng took the ransom and returned to the cabin, he tied Chen Feng up again and caused problems to you and Guan Hua. Chen Feng has always been tied to the pillar, so that Chen Feng can have you help him prove that Chen Feng never left the cabin at the time of the crime, so he has a perfect alibi."

"I see... No wonder I fell asleep after drinking beer. I tried hard to pinch my thighs to prevent myself from falling asleep, but it was still useless. Alas, I never thought that I would be betrayed by my elder brother. Fortunately, Either I let Chen Feng go, or I am an accomplice to murder, which is much more serious than kidnapping and extortion."

"Everyone who is a younger brother must be used by the older brother. Otherwise, why would the older brother raise a younger brother? So there is no future in hanging around with the older brother. Where do you throw the empty beer cans?"

"We threw the beer cans on the ground of the cabin and fell asleep within five minutes."

"How did you wake up?"

"I felt like my arm was bitten by an insect and woke up. When I woke up, I saw Brother Xu... No, it's not Brother Xu now, it's Xu Dongfang... He slapped my face with his hand and told me to break up with Xiaoguan. Money, so he took out 10 yuan and handed it to me, and then took out another 10 yuan and handed it to Xiaoguan, and then told us to go down the mountain quickly. It was best to go separately, so we took the money and went down the mountain. Unexpectedly, You actually waited for us to be arrested at the foot of the mountain. I really admire you."

"We hope you will learn this lesson, be a good person, and never do anything illegal. Let me see your arm." Jiang Yiming walked up to him, picked up his arm, and looked carefully, only to see a pinprick. , "My guess is indeed correct. You were not bitten by bugs, but Xu Dongfang injected you with the antidote."

"The antidote? What antidote?"

"For example, drugs such as barbiturates or chloral hydrate can detoxify anesthetics. It depends on which anesthetic you drink." After Jiang Yiming finished speaking, he asked the guards to take him away. , and then brought Guan Hua for interrogation. As a result, his statement was similar to that of Li Xiaoqing.

Now the clues are very clear. Chen Feng is suspected of murder, and Xu Dongfang is an accomplice. But I don't know what hatred they have towards Xiong Fei or any major conflicts of interest.

Jiang Yiming asked Zhou Ting and Luo Jin to go to the cabin in Nankeng Valley to look for beer cans. Because he did not expect that the case was so complicated and that there was a case within the case, he did not conduct an investigation on the cabin and was just in a hurry to rescue him. Chen Feng.

As soon as they entered the cabin, they found three beer cans on the ground, as well as 8 empty instant noodles shells, 4 cigarette boxes, 28 cigarette butts, three plastic spoons, a piece of black tape, etc.

They tried to find the tire marks of the motorcycle from the mountain, and soon found it. However, the pattern of the tire tracks had been washed away by the rain and was beyond recognition. There were only blurry marks. Zhou Ting took pictures of the tire marks and saved them on his mobile phone.

They searched all the way from the bottom of Nankeng Valley to the direction of Luyin Villa. After searching for a long time, they found no new tire marks. This meant that they might have looked in the wrong direction. If Chen Feng passed by on the grass on a motorcycle, he would have been missing since the incident. It's been a week and the grass that was knocked down by the tires has returned to its original shape, so there are no tire tracks to be found.

At this time, the sun has set in the west, the sky is getting dark, a cool breeze is blowing in the valley, and the birds are calling each other home to their nests.Jiang Yiming had no choice but to call everyone back to the team.

When Jiang Yiming and Zhou Ting were eating in the cafeteria, Wu Jiang and Xiao Ke came back. After eating, they sat down in front of Jiang Yiming.Wu Jiang said: “We interviewed two of Chen Feng’s friends, one of whom was Li Zhun. He said that when Chen Feng was young, he used to be a cross-country motorcycle rider. At the age of 28, he won the provincial motorcycle championship. He was the third runner-up in cross-country and did not participate in the competition until he was 35 years old.”

"Does Chen Feng have an off-road motorcycle?" Jiang Yiming asked.

"No, but Li Zhun has a motorcycle. Chen Feng borrowed a motorcycle from Li Zhun on August 8. Li Zhun didn't want to borrow it at first, but because Chen Feng was his bike friend, he lent the motorcycle to him. Chen Feng, it was not until the evening of August 16 that Chen Feng returned the motorcycle to Li Zhun." Wu Jiang said while eating.

"Has the motorcycle been washed?" Jiang Yiming thought: If the motorcycle has not been washed, the soil from Green Mountain Villa will definitely be stuck to the wheels, and the soil composition of each mountain is slightly different. As long as it can be proven that the motorcycle has been there Chen Feng is a huge suspect in Luyin Villa.

"It's a pity that Chen Feng said that the motorcycle was dirty. He took it to a car wash shop and cleaned it. He told Li Zhun that he could use it without worry. Chen Feng was really cunning and didn't leave any traces." Wu Jiang regretfully said answer.

"No, some traces cannot be washed away, such as blood stains... Have you brought Li Zhun's motorcycle back to the team?"

"Bring it back, Li Zhun didn't agree at first, but we gave him a stern warning: If he refused to hand over the motorcycle to us, we would treat him as a suspect and investigate him in depth. He was scared, so he had to Give us the keys to the motorcycle." "Now all the evidence points to Chen Feng. We must keep him under surveillance and then look for evidence. When Chen Feng killed Xiong Fei, bears would be sprayed on his clothes, pants, and shoes. Fei's blood stains, if he had not thrown away the clothes, a search of his home and lumber store might have yielded evidence."

"Judging from Chen Feng's IQ, it is extremely unlikely that he would have brought the blood-stained clothes home. I think it is very likely that he would have buried the blood-stained clothes on the roadside on the way back from Luyin Villa to the cabin in Nankeng Valley." Xiao Ke said.

"We saw Chen Feng wearing sportswear and sneakers in the surveillance video of Luyin Villa. But two hours later, when we went to rescue him, he was wearing a T-shirt, jeans and leather shoes. This also proves that Chen Feng They buried or threw their sportswear and sneakers on the way back to Nankeng Valley.”

"Yes... but how can we find this evidence? If he burns his shoes and clothes, we won't be able to find it." Zhou Ting said worriedly.

"The possibility of burning is relatively small. Even if it is burned, it is difficult to burn the soles of sports shoes. If there are Xiong Fei's blood stains on them, we can ask Xiao Bing to search with blood tracking dogs. When Luo Jin dissected the body, There must be Xiong Fei's blood, which can be used as a smell source." Jiang Yiming said.

"When Luo Jin tests the substances in the beer cans extracted from the wooden house tomorrow, we will know whether Li Xiaoqing and Guan Hua drank anesthetics and what kind of anesthetics they drank."

"We will take action tomorrow and ask Xiao Bing to bring two blood tracking dogs. One will track from the No. 5 monitor of Luyin Villa to Nankeng Valley; the other will track from Nankeng Valley to Luyin Villa and finally meet in the middle. This will It’s much faster, because it’s only more than 4 kilometers from Dornankenggu to Luyin Villa.” Jiang Yiming said that he was full.

"Xiao Ke and I will work overtime for a while and use blue light occult blood reagents to check whether there are blood stains on the motorcycle. If there are blood stains, then there is no need to mobilize the blood tracking dog." Wu Jiang said.

"No, Chen Feng can be said to have stained Xiong Fei's blood on the motorcycle. Only by finding the shoes and clothes worn by Chen Feng can he be convinced and unable to defend himself. Because there must be Chen Feng on the clothes and shoes. Biological samples." Jiang Yiming shook his head and said.

"You're right. Don't make mistakes like the Huang Taohe case. Make sure the suspect is convinced."

Jiang Yiming called Huang Hua, the leader of the surveillance team, and asked him to lead people to monitor Chen Feng 24 hours a day. He must not be allowed to abscond or be silenced.Huang Hua promised to do it immediately and promised to call and report to Jiang Yiming after the arrangements were made.Jiang Yiming felt a little relieved now. He believed in the capabilities of the surveillance team.

When he went to work the next day, Luo Jin came to Jiang Yiming's office and told him: Scopolamine was detected in the beer can.Scopolamine is also called devil's breath. A dose of 0.3 to 0.6 mg can make people lose consciousness in just a few seconds.Scopolamine is the most powerful alkaloid in belladonna. It can be used to block parasympathetic nerves and can also be used as a central nervous system depressant.

"As expected, Xu Dongfang stunned Guan Hua and Li Xiaoqing with scopolamine, and it was also Xu Dongfang who let Chen Feng go. Xu Dongfang committed kidnapping and murder. If he is caught and brought to justice, he will be sentenced to death or life imprisonment. So, just in case, he escaped that night. Fortunately, Chen Feng is still under our control."

At this time, Wu Jiang also came to the office. He said to Jiang Yiming: "We did not find any blood stains from Li Zhun's motorcycle, but we extracted sweat from the handle. This does not mean anything. If the sweat is Chen Feng's, it can only prove that He has used this motorcycle, and it would be even more meaningless if it was Li Zhun’s sweat.”

"No matter what, the sweat must be used for DNA comparison. You can give the sample to Luo Jin. Xiao Bing and his assistant Jin Guang have brought two blood tracking dogs. On the way, you and Xiao Ke and Xiao Rou cooperated with the golden belt tracking dog to track from Nankeng Valley to Luyin Villa, and Zhou Ting, Yingying and I cooperated with Xiao Bing to track from Luyin Villa to Nankeng Valley." Jiang Yiming told Wu Jiang.

"Okay." Wu Jiang said and went out with Luo Jin.

Since Jiang Yiming arranged for Huang Hua to monitor Chen Feng yesterday, he has not received any news from Huang Hua. Jiang Yiming is a little worried. In fact, no news is good news. If Chen Feng escapes, Huang Hua will definitely call him and report to him. Condition.

However, Jiang Yiming still called Huang Hua's mobile phone and asked: "How is Chen Feng's situation? Where is he now?"

"Everything is under our control. Don't worry. At this time, Chen Feng is sitting in his wood shop and drinking tea leisurely." Huang Hua replied.

"You must keep an eye on him. He is very cunning and cunning and will be very difficult to deal with."

"Well, I'll keep it in mind. Unless he grows wings and flies away, he won't leave our sight."

"If you find that he shows signs of escaping, capture him immediately. You have to be tougher when dealing with such people. You don't have to stick to the rules. If there are any adverse consequences, I will bear the responsibility." Jiang Yiming said domineeringly.

"I understand. I will follow your instructions."

After Jiang Yiming hung up the phone, he walked to the door of the office area and found that except Luo Jin, the other team members were getting ready at the door.Xiao Bing and Jin Guang were chatting with everyone. When Jiang Yiming arrived, Xiao Bing said to him: "Captain Jiang, forensic doctor Luo has given us Xiong Fei's blood sample as a source of smell. As long as the suspect throws the blood clothes on the mountain, or Buried in the ground, tracking dogs can sniff it out."

"I feel relieved now. Get in the car." Jiang Yiming asked Xiao Bing to ride in the same car with him.After Xiao Bing got in the car, Zhou Ting drove to Luyin Villa. Lu Yingying sat in the passenger seat, and Jiang Yiming, Xiao Bing and the tracking dog sat in the back seat.

They parked the car between No. 5 and No. 6 monitors of Green Villa. After getting off the car, Xiao Bing gave the tracking dog the sniff source. It only sniffed for a moment and then nodded to indicate that it remembered.So, it climbed up the hillside and looked all the way towards Nankeng Valley.

The blood tracking dogs trained by Xiao Bing are very good. This tracking dog named Xiaohu can successfully sniff out a blood sample diluted 5 trillion times in just 2000 minutes, and set a record of continuous tracking of 200 kilometers in half a month. Blood stains can be traced inside it, and it is said to have 3.5 million olfactory cells.

Everyone's blood has five characteristics: residual, sporadic, variability, specificity, and adhesion.The real experts in solving crimes are animals. No matter where the criminal suspect escapes or uses any method to cover up, the smell can be found by police dogs, making it impossible for him to escape the law.

When the tracking dog tracked for about two kilometers, it barked at the bottom of a rock. Xiao Bing was very excited and said to Jiang Yiming: "The little tiger is really amazing. It has found what you want." Xiao Bing ran forward and Seeing a small pile of new soil, the little tiger cupped the soil with his mouth.

Zhou Ting asked Xiao Bing to order Xiaohu to stop and let him dig.So Xiao Bing asked Xiaohu to stand aside. Zhou Ting took out a folding shovel, inserted the shovel hard into the soil, and dug out the soil. When he dug 20 centimeters, he saw a black sportswear.

Zhou Ting continued digging, and after a while, another pair of Anta sneakers were revealed. There were splatters of blood on the uppers and uppers. Although the blood stains had changed color, they would not hinder DNA testing.There was also a lot of blood on the tracksuit.

Zhou Ting put the sportswear into the investigation box, lowered the lid of the box to block most of the light, and used a multi-band light source to illuminate it. He found that there were splatter-shaped blood spots on it, which were in the shape of lines. This showed that Chen Feng was killing. When Xiong Fei flew, Xiong Fei's blood splashed onto Chen Feng's body.They then found a pair of blue jeans with blood still visible on them.

Everyone returned victorious.
