The fact that the other party revealed his cards after a slight scare was enough to show that the other party was not a person with a firm mind.
Han Bin was a bit more confident in the following interrogation.
In order to prevent the news from being leaked, Han Bin immediately took Gao Xiaopo back to the Municipal Public Security Bureau for interrogation.
Gao Xiaopo sat on the interrogation chair and looked around in panic. His slightly trembling hands were enough to prove his nervousness.
On the way back, Han Bin asked someone to check his situation. Gao Xiaopo was not old, only 26 years old, but he already had two convictions for theft and one for affray.
"Gao Xiaopo, do you know why we arrested you? Think carefully this time before you speak. "
Gao Xiaopo slowly said, "I shouldn't have held dangerous items."
"Are you trying to squeeze toothpaste from me? Have you ever thought about how the police could arrest you? Have you ever thought about who put the 2500 yuan there? Let me tell you, I'm giving you a chance to reduce your sentence by making you answer voluntarily. Don't be ungrateful. "
"I … I know I'm wrong, I shouldn't …" Gao Xiaopo said halfway and began to mumble.
"Shouldn't what? Speak. "
"I shouldn't have sold dangerous items."
"You admit that you're selling sodium cyanide?"
"Yes."
"How long has it been?"
"First … first time."
"I know it's your first time being arrested. I'm asking you when you started selling. Think carefully before you speak. It's not fun to lie to the police."
"It's been half a month."
"You're still avoiding the important points?"
"No, I'm telling the truth."
"Gao Xiaopo, the police have been watching you for a long time. We haven't done anything yet because we're collecting evidence of your crimes. To tell you the truth, with the evidence we have now, even if you don't say anything, we can still convict you. Now that you're taking the initiative to confess, you're fighting for a chance to reduce your sentence. Whether you're lying or avoiding the important points, it won't do you any good. Instead, you'll lose the chance to reduce your sentence. "
Gao Xiaopo panicked and quickly said, "Police comrade, I know I'm wrong. I'm willing to confess. I'll tell you everything this time."
"Answer my previous question."
"I've been doing it for about half a year."
"On April 17th, did you make a transaction at Guangnan Mall?"
"Let me think … No.17 …" Gao Xiaopo recalled for a while. "Yes, No.17 made a deal."
"What are you selling?"
"Also sodium cyanide."
"Tell me the details of the transaction."
"I remember that the money and the goods were separated. I took the money on the 16th, and the goods were delivered on the 17th."
"Where did you get the money? Where did you get the goods? "
"The money should have been taken from Theater 1, and the goods should have been placed in the water tank in the toilet. I don't remember exactly which floor's toilet."
"Who did you trade with?"
"I don't know. I'm only responsible for delivering the goods. I've never had any contact with customers."
"Who is your online contact?"
"Brother K, I only contact him. He also told me the delivery location. I'm just an errand boy."
"How do you contact Brother K?"
"Contact me through WeChat. His WeChat name is Brother K. "
Han Bin picked up Gao Xiaopo's mobile phone from the table and found Brother K in the contact list. "Is this him?"
"Yes, it's him."
Han Bin looked through the chat history. From the content of the chat, Brother K was indeed his online contact.
The WeChat ID that Li Qin had been in contact with was called Old K, which was probably the same person as Brother K, just using a different WeChat ID.
Han Bin said to Li Qin, "Sister Li, go and check this WeChat ID and registered mobile phone number."
"Yes."
After Li Qin left, Han Bin continued to ask, "Have you met Brother K?"
"No."
"You dared to cooperate with him without meeting him?"
"We spoke in the same chat group. Later, he added me and asked me if I wanted to get rich. I was short of money at that time, so I agreed. He asked me to go and get the money. At first, I was skeptical, but I really found the money at the place he said. I was in a difficult situation at that time, and suddenly I had a few thousand yuan more. I was in deep trouble. "
"What chat group?"
"The chat group was called 'Super High Tonight'. It was banned, and I left it later."
"What else do you sell besides sodium cyanide?"
"Knockout Powder, Dolantin, and Amphetamine."
"You sell quite a lot of things."
"I'm just an errand boy. I do whatever Brother K asks me to do."
"Where did you hide the drugs?"
"In my rental house."
"Address?"
"Guanqian Road, Wushan District, Building 7, Unit 1, 203."
"Where did the goods come from?"
"Brother K gave it to me."
"How did he give it to you?"
"He sent it to me by express delivery."
"Where's the money?"
"I also sent it to him by express delivery."
"Tell me the mailing address, name, ID, and mobile number."
"It's from Baiziyuan District, Yuxiang Road, Dianzhou Post Office. Name Wu Yongzhen. Mobile number 1352384 xxxx."
"When was the last time he sent it to you?"
"Early April. I think I received it on the 5th of April."
Han Bin recorded it in his notebook. He could check the records at the express delivery company later.
"How many times have you traded goods? Where are the places? "
"I … I don't remember clearly."
"You should know that you're selling illegal drugs. Everyone who buys the drugs could be a potential criminal suspect. Helping us find these potential criminals is also a meritorious act."
"It's been a long time. I only remember part of it. I really don't remember the other part."
"Tell me what you remember."
…
The next morning.
The Municipal Criminal Investigation Unit held a video conference in the conference room.
The video was connected in three places: Qindao, Dianzhou, and Shuzhou.
Han Bin, Ding Xifeng, Wang Xiao, and Zhu Jiaxu participated in the video conference.
Because there were only four people, everyone was more casual.
Ding Xifeng took out a pack of cigarettes and handed one to Han Bin. He also smoked one himself. "Leader Wang, Leader Zhu, how's the situation on your side?"
Zhu Jiaxu said, "Captain, I'll speak first. My location is a bit remote, so the signal isn't good."
"Speak."
"Yesterday, I rushed to Shuzhou overnight. I arrived at the town near Li Guo Shan at around nine in the morning. I first went to the local police station to understand the situation. Because Li Guo Shan's village is a bit remote, the police station didn't know much about Li Guo Shan's situation. He Yingsheng and I entered the village under the guidance of the local police station's officers.
According to them, Li Guo Shan's health hasn't been good for the past two years. He's been staying in the village and hasn't been seen going out. I checked around the village. The village isn't big, and most of the roads are mountain roads. It's not easy to leave the village. Even if you leave the village, it's hard not to be seen by the other villagers. I feel that the villagers' words have some credibility.
After understanding the situation, I don't think Li Guo Shan is a suspect, so I gave him a statement. "
Zhu Jiaxu paused and continued, "After I saw Li Guo Shan, I realized that his condition isn't good. One of his legs and one of his arms aren't very agile. He's the only one living at home. His family's living conditions are quite poor, so it doesn't seem like he's faking it.
I talked to him and found out that when he went out to work a few years ago, someone bought his identity card and sent him a sum of money every year. It's about five thousand yuan a year. Although it's not a lot, it's still quite a fortune for Li Guo Shan, who's living conditions are quite poor. "
Han Bin asked, "How did the money go to him?"
"Bank transfer. The person who transferred the money was also Li Guo Shan."
"In other words, the suspect used Li Guo Shan's bank account to transfer money to another account?"
"Yes."
"How did he transfer the money?"
"Bank A f * cking machine. The address is a branch on Yuxiang Road in Dianzhou."
Han Bin noted down in his notebook that this clue matched the suspect's address that Gao Xiaopo had provided.
Zhu Jiaxu said, "That's basically what I know."
Wang Xiao continued, "I rushed to Dianzhou overnight and went to the local police station to understand the situation. Then, I went to the courier station to investigate the man who used Li Guo Shan's name to send the mail. We found that the man used Li Guo Shan's account to send mail to several nearby courier stations. We successfully obtained the man's surveillance screenshots.
Currently, we've asked the local police station to assist in the investigation and arrest. "
Han Bin asked, "Where are the addresses of the mail?"
"Near Da Wang Road."
Han Bin rubbed his forehead and went through the two's report in his mind. He then said, "The suspect who provided Ma Xiaolin with sodium cyanide has been arrested. The man's name is Gao Xiaopo, and he's just an ordinary henchman. He's only responsible for withdrawing money and delivering the goods. He's not responsible for contacting the customer.
As for the source, it was sent to him by a man named Wu Yongzhen. The address was Baiziyuan District, Yuxiang Road, Dianzhou. The phone number was 1352384 xxxx.
In addition, we found a large number of illegal drugs in Gao Xiaopo's home. In addition to sodium cyanide, there was also knockout powder. After testing by the technical department, the composition and purity of the sodium cyanide sold by Gao Xiaopo and the poison found in the body of the deceased Chen Zihe are almost exactly the same. It can be confirmed that Ma Xiaolin bought the sodium cyanide from Gao Xiaopo.
In addition, the composition and purity of the knockout powder found in Gao Xiaopo's home and the knockout powder purchased by Han Zikang are almost exactly the same. It can be confirmed that they are from the same source. "
Wang Xiao said, "In other words, Wu Yongzhen is probably the person who used Li Guo Shan's identity to send the delivery to Han Zikang?"
Han Bin said, "According to Wu Yongzhen's identity information, we found his ID photo in the database of the public security system. You can check if it's the same person."
Han Bin sent the photo to the WeChat group.
After a while, Wang Xiao said, "It doesn't look like the same person. From the surveillance screenshots, the man who sent the delivery is obviously younger than Wu Yongzhen."
Ding Xifeng said, "I also think that they shouldn't be the same person. This Wu Yongzhen is obviously a level higher than the man who sent the delivery, and he hides his identity deeper. It's very likely that he is his superior."
Although the police first found out Wu Yongzhen's identity, it was through Gao Xiaopo, who was Wu Yongzhen's henchman.
Han Zikang bought the knockout powder through online shopping, and the person who sent him the delivery was likely to be one of his henchmen, the man in the surveillance video of the delivery station. He should be at the same level as Gao Xiaopo, and Wu Yongzhen was likely to be their superior.
This case currently involved a total of five people. The first person who was exposed was Li Guo Shan, the second was Gao Xiaopo, the third was the man in the surveillance video of the delivery station, the fourth was Wu Yongzhen, and the fifth was Old K, who was abroad.
Han Bin sent someone to the WeChat company to investigate and found that Brother K, who sent the WeChat message to Gao Xiaopo, also had an IP login address in Myanmar. Therefore, Old K and Brother K were likely to be the same person, just using different WeChat accounts. This was also a kind of protection for Gao Xiaopo.
Looking at the current situation, Old K should be at the top of the sales channel, and was remotely controlled from abroad.
His subordinate was Wu Yongzhen, who was in charge of the two sales channels in China. One of the sales channels was Gao Xiaopo, and the other was the man in the surveillance video of the delivery station. As for Li Guo Shan, he was just a scapegoat.
Ding Xifeng concluded, "Gao Xiaopo has been arrested, and now the target is Wu Yongzhen and the man in the surveillance video. As for Old K, it will be difficult to catch him. I will ask the higher-ups to see if we can ask the Myanmar police to help with the arrest.
I will rearrange the mission. Since the two suspects are in Dian Zhou, Han Bin, get ready to take your team to Dian Zhou to carry out the arrest. "
"Yes."
"Zhu Jiaxu, since there are no problems with Li Guo Shan, you and He Yingsheng return to Qin Island first."
Zhu Jiaxu said, "Captain, should we go to Dian Zhou to help with the arrest?"
"Don't go to Dian Zhou, there are other missions waiting for you on Qin Island." Ding Xifeng had other plans.
Han Shaokang and Ma Xiaolin definitely weren't the only two customers in these two sales channels.
Although Old K was abroad and the police couldn't catch him, they could still find his WeChat contacts. Every one of his WeChat contacts could be a customer who bought illegal drugs.
Similarly, the website that sold the drugs was bound to Li Guo Shan's account. As long as they traced Li Guo Shan's account, they would be able to find out who had bought illegal drugs.
Ding Xifeng asked Zhu Jiaxu to return to Qin Island because he wanted him to be in charge of this matter. Although this task wasn't as urgent as arresting the suspects, it was still important.
Han Bin packed his luggage and that night, he took a plane to Dian Zhou with a few Second Squadron members.
Han Bin didn't stay idle on the plane. He had been looking through the information that Wang Xiao had sent over and studying the surveillance video of the delivery man to make sure that he could recognize him at first glance.
Although they had already caught one of the suspects, Gao Xiaopo, Han Bin still didn't dare to be careless. Because Gao Xiaopo and Wu Yongzhen were thousands of miles apart, their relationship couldn't be considered close. Therefore, after the police arrested Gao Xiaopo, his online contacts, Wu Yongzhen and Old K, didn't notice anything unusual.
However, the situation in Dian Zhou was different. Wu Yongzhen and the delivery man in the surveillance video were in the same city, and the streets that the two often appeared on weren't far from each other. Han Bin analyzed that the relationship between the two might be unusual. If they couldn't pry open one of the suspects' mouth in time, the other suspect might be alerted and escape.
Dian Zhou was close to the border, and the suspects were likely to flee to neighboring countries, making it very difficult to arrest them.
The best way was to arrest both suspects at the same time.
To do this, a lot of preparation work was needed.
