Serious Crime Unit 1

Chapter 999 Death of the Scavenger (6)
"Okay, I will definitely cooperate with you to solve the case." Even his voice was like a girl's, very slender. He was not surprised at all by the arrival of Wu Jiang and Xiao Ke, as if he was waiting for this day to come. When he spoke I like to tease my long hair with my hands.

"I heard that you and Ma Er have a good relationship. You often bring good wine to his house to drink. Tonghe Village is nearly 3 kilometers away from Xi'ao. Why do you travel so far to give him wine? There is such a big age gap between you. There is no common language.”

"Maybe it's fate. Of course, I met him because he would buy some of my scrap copper and iron at relatively favorable prices, so I recognized him. The main reason is that we both have a common hobby - drinking. , I don’t know why, when I drink with him, I feel like I’m on drugs, I’m so happy, and my words keep flowing like an open reservoir. I’m an unemployed vagrant, not recognized by others, and I feel very inferior inside, but in front of him , I was treated like a prince by him, which is why I like drinking with him.”

"I heard that your parents only give you 2000 yuan a month for living expenses. Why can you afford Jiannanchun wine?"

"I play "World of Warcraft" and "Fantasy Westward Journey" at a very high level. Someone asks me to be a power leveler. I can make money from it, no less than 3000 yuan per month. If I work harder, I will earn more. Of course, I also like to hang out at construction sites, pick up some valuable metal and sell it as scrap, and I can also make money from it, so I can still support myself without having to work." He stretched his head to the left and reached into the trash can next to the coffee table. Spit in the trash can.

"Excuse me, where were you from 8 pm to 7 pm on August 3? What were you doing?"

"Why are you asking this?"

"Because this is the time Ma Er was killed, you must tell us."

"What? Do you regard me as a murderer? How could I kill my good friend?" he asked in surprise.

"It's hard to know the heart when you know the person. Everyone who has anything to do with Ma Er is our suspect, and you are no exception."

“I am a homebody and spend most of my time at home playing games. I usually play all night long and don’t go to bed until dawn. I sleep until dusk and then wake up. After I wake up, I order dinner on Ele.me. , after dinner, I started playing games again, and so on. So, I must have been playing games at home that day."

"Anyone prove it?"

"No, firstly, I don't live with my parents, and secondly, I don't have a wife or children. How can anyone help me testify?"

"Please tell me your account and login password for playing "World of Warcraft" and "Fantasy Westward Journey"." Wu Jiang didn't believe him. If he could make money playing games, why would he go to the construction site to pick up scrap copper and sell it to Where is Ma Er?

"This... this is my privacy... you can't force me!" He looked distant.

"If you don't agree, we will ask you to go to the criminal police team. Maybe you will agree when you get there. We have the right to summon the suspect for 24 hours." Xiao Ke looked at him like that and felt that he was more It's suspicious.

"Okay, I'll log in to the computer and show it to you." He stood up, walked to the computer, started the computer, entered the desktop, then opened "World of Warcraft", entered the password, and let them see it.Wu Jiang and Xiao Ke have never played games before, and they don’t know how to operate them at all. However, as long as they know Jiang Shan’s account and password, and go back to the team and ask Lu Yingying to check, they will know whether Jiang Shan has really played to a level where he can help others train. .

Xiaoke took photos of Jiangshan and videotaped his walking posture, and then extracted his fingerprints and saliva.

They walked out of Jiangshan's home and went downstairs, looking for monitors everywhere. They found several monitors, but they were all too far away from Jiangshan's home, and the monitors did not fully cover them. There were many blind spots. If Jiangshan avoided the monitors, If you run to the scene to commit a crime, the surveillance camera will not be able to capture it.

Wu Jiang and Xiao Ke went to the Tonghe Village Police Station to learn about Jiangshan's situation. They learned from the deputy director: Jiangshan was once arrested for stealing cables from a construction site, but because the amount was not large and the value was not high, he was only detained. He was given 15 days and fined 5000 yuan.It turns out that Jiang Shan is a thief. He may not only steal outdoor cables, but also break into houses, and the Jiannanchun wine he brought to Ma Er's house to drink may have been stolen.

After they returned to the team, they showed Jiangshan's photos to Lu Yingying and Wen Xiaorou, and asked them if they had seen Jiangshan in the surveillance video at the crime scene.They both shook their heads and said they were not impressed.Wu Jiang had no choice but to give Jiangshan's "World of Warcraft" account and login password to Lu Yingying, and asked her to see if Jiangshan could make money by playing "World of Warcraft".

Wu Jiang reported Jiang Shan's visit to Jiang Yiming. After hearing this, Jiang Yiming thought for a moment and said, "Jiang Shan is a thief and very suspicious. Ye Hao said that he and Ma Er both settled in cash. If Ma Er had a large amount of If the cash is hidden at home, then Jiang Shan is very likely to sneak into Ma Er's home and steal it. If Ma Er suddenly comes home due to business and bumps into Jiang Shan while he is stealing, Jiang Shan will most likely jump over the wall and kill Ma Er." "Your analysis makes sense." Wu Jiang said.

At this time, Lu Yingying walked into Jiang Yiming's office and saw that Wu Jiang was there, so she said to him: "Brother Ang, I logged into Jiangshan's account for playing "World of Warcraft" and found that he was a rookie. He was only in the junior stage and often bought money from others. It’s absolutely impossible to make money by helping people train with equipment.”

"Jiang Shan really lied to us. In order to buy equipment, he most likely stole Ma Er's money. His suspicion is getting bigger and bigger."

"Yingying, did your visual investigation team find Jiang Shan in the surveillance video during the time of the crime?"

"No, the crime scene is an open place that can be entered from all directions. If someone knows the distribution of the monitors, they can avoid the monitors and enter the scene."

While he was talking, Jiang Yiming's cell phone rang. It was Lu Hongzhu calling. Jiang Yiming thought she might have clues for him, so he pressed the answer button: "Hello, Ms. Lu, what can I do for you?"

"I thought about it and thought that Lao Ma might have been killed by a thief because he hid many months of cash under the bed. If the thief was caught by Lao Ma during the theft, the thief would definitely attack him. .”

"Who else knows about this?"

"I don't know anyone but me who knew. One night I was staying over at his house, it was my birthday, and I got up in the morning to go to work, and he lifted up the mattress and took something out of a black plastic bag. Give me 300 yuan and ask me to buy new clothes."

"The information you provided me is very important. Thank you. We are getting closer and closer to the murderer. Don't worry, we will definitely arrest the murderer and redress Ma Er's injustice!" Jiang Yiming said after hanging up the phone, "Jiang Shan The suspicion is even greater, but unfortunately we have no evidence of his murder."

"How about summoning him for a polygraph test? If he lies, we will conduct an in-depth investigation on him." Wu Jiang said.Jiang Yiming agreed.

Wu Jiang and Xiao Ke immediately went to summon Jiang Shan. An hour later, Jiang Shan was taken to the criminal police team by Wu Jiang and Xiao Ke. He came to the polygraph room with a tired face and a very calm expression, as if he had not lied at all.

Lu Yingying and Wen Xiaorou conducted a lie detector test on Jiang Shan. Lu Yingying clamped the conductive wire on Jiang Shan's middle finger, then started the lie detector and asked him questions based on common lie detector questions. It took them nearly an hour, and the result of the lie detector test was It was proved that Jiang Shan did not lie, which surprised everyone: Could it be that he was not the murderer?

Today's lie detectors are very sensitive, and it is difficult for a liar to escape the lie detector.Lu Yingying was puzzled... She went to Luo Jin and asked him if there was any way to escape the polygraph?
Luo Jin said: "Except for professionally trained people, such as senior agents and spies, no one can fool the lie detector... Of course, if the person being tested has deodorant on their hands or is born with the ability to secrete ocean odor If the compound is used, it is very likely to fool the lie detector."

"The possibility of Jiangshan escaping the lie detector test is extremely low with special training, otherwise he would not be a thief or a thief... Oh, I remembered. When I was clamping the wires for Jiangshan just now, I smelled something on him. The smell, I thought it was perfume at first, but it turned out to be the smell of deodorant. This country is so cunning, how dare you play tricks on me!" Lu Yingying was very annoyed.

She walked into the detention room and saw Jiang Shan sitting there, leisurely playing games on his mobile phone. She quickly approached him, snatched his mobile phone away, then raised his hand to her nose and smelled it. With the faint smell of spices, she said loudly: "Jiangshan, you are so cunning. You even put deodorant on your hands to fool the lie detector. Come on, follow me to the bathroom to wash your hands."

Jiang Shan's face instantly turned as pale as snow, and a huge pressure hit him. He felt that his end was coming, his hands and feet were shaking, and he couldn't stand up.Lu Yingying asked Zhou Ting and Xiao Ke to take him to the bathroom to wash his hands.The two of them walked up to Jiang Shan, each grabbed one of his hands and took him to wash his hands.

After washing his hands, Zhou Ting and Xiao Ke took him to the polygraph room again. Lu Yingying took a second lie detector test on him, and the polygraph test proved that he was lying.Therefore, everyone identified Jiang Shan as the murderer, otherwise he would not have found ways to evade the polygraph.

The next step is to find evidence of his murder.Wu Jiang remembered that when he visited Jiangshan, there was a small safe in the living room of his house. If he had stolen Ma Er's money, he would probably have put the money in the safe. As long as his house was searched, it should be possible There is gain.
