Municipal Criminal Investigation Brigade, Chief's Office.
"Dong dong." Han Bin knocked on the door.
"Come in."
Han Bin walked in with the documents.
Ding Xifeng stood up from his desk, pointed to the sofa beside him, "Sit down, I'm done asking."
"yes."
"Here is the detailed interrogation record."
"Yeah." Ding Xifeng sat on the sofa and began to look through the interrogation records.
Han Bin was not in a hurry, lit a cigarette, and smoked on his own.
After a while, Ding Xifeng finished reading the document and said, "Do you think this transcript is credible? Is it possible that Ma Xiaolin lied about it?"
"I don't think it's possible to lie."
Ding Xifeng said, "Cyanide is the key evidence for conviction. Ma Xiaolin destroyed the rest of the cyanide. It cannot be compared with the poison components in the deceased. After all, it is a weak link. If the source and samples of cyanide cannot be found, then What I know about the prosecutor's office, it may be returned on the grounds of insufficient evidence.
Don't look for that troublesome thing, don't think that you will relax after you catch someone, our business is most taboo about anticlimax. "
"Don't worry, I will investigate quickly."
"Tell me, how do you want to investigate?"
Han Bin thought for a while, "Ma Xiaolin has never met the seller of cyanide, but they have indirect contact.
It can be roughly divided into two types. One is to contact through the WeChat network, but the IP address is in Myanmar, and it is difficult to find a specific location.
The second is the contact in the shopping mall. Although there is no direct meeting, there must be a contact person for Ma Xiaolin to send money and pick up the goods. As long as we catch this contact person, we can follow the clues to catch the suspect. "
Ding Xifeng lit a cigarette, "You want to lure the snake out of the hole."
"yes."
"The plan is quite satisfactory, but the plan must be careful and consider the situation clearly, so as not to startle the snake."
"I already have a rough plan in mind, and I'm about to report it to you..."
"Dong dong..." There was another knock on the door outside.
"Enter."
There was a knock at the door, and both Wang Xiao and Zhu Jiaxu walked in.
"Is it over with Han Zikang?"
Wang Xiao replied, "Yes, I made another detailed record for him, recording the process of his purchase of M medicine and his contact with the seller."
"Just in time, I'm talking about Ma Xiaolin's purchasing channel for sodium cyanide with your Korean team. Compare the two purchasing channels to see if there is anything in common."
"Yes." Wang Xiao responded and handed Ding Xifeng a document, "Captain, this is Han Shaokang's interrogation record."
"I've read the interrogation records of the police station, and I probably know everything about it. Just focus on the key points."
"Cough..." Wang Xiao cleared his throat, "Han Shaokang's process of buying M medicine is not much different from ordinary online shopping platforms. He just searched for M medicine on the Internet, and a website popped up. He bought it through the website and used WeChat to buy it. Pay. After that, the seller sent the M item by courier.
I asked people from the technical department to check this website. Judging from the domain name, the server of the pirated website is located abroad, probably in a country in Southeast Asia.
The owner of the bank account bound to the website is Li Guoshan, who is from Shuzhou. The police station also learned about this person during the investigation. Li Guoshan is 61 years old this year and lives in Xiaobeng Village, Shuzhou.
According to reports from the local police station, Li Guoshan is not in good health. He has been farming in his hometown for several years, and the transportation and express delivery there are inconvenient. He is unlikely to do such illegal things. "
Wang Xiao paused, and continued, "Another focus of investigation is the express delivery. The police station also checked the consignor of Han Shaokang's M medicine. The consignor's name is Li Guoshan, and his ID number is also Li Guoshan's, but The delivery address is in Dianzhou.
It is several provinces away from Shuzhou, and I personally feel that Li Guoshan is unlikely to go so far to deliver the goods, and the small amount of money for the goods is not enough for round-trip air tickets and accommodation. "
Zhu Jiaxu asked, "Do you think Li Guoshan is just a puppet pushed by the suspect?"
Wang Xiao said, "Almost, maybe not even a puppet, it can only be regarded as a shield."
Ding Xifeng pondered for a moment, then looked at Han Bin beside him, "Captain Han, what do you think?"
Han Bin said, "Although judging from the current situation, these two cases are not directly related, but if we analyze them carefully, there are still certain coincidences and connections.
Ma Xiaolin bought cyanide from a seller whose WeChat login address is displayed in Myanmar. The server of Han Shaokang's website for purchasing M medicine is also in Southeast Asia. Although the specific location has not been confirmed, it may also be in Myanmar.
From this analysis, the two cases are likely to have a certain connection, and may even have a common source of goods. "
Ding Xifeng asked, "Has the police station sent anyone to Shuzhou to investigate Li Guoshan?"
"No, although the police station felt that Li Guoshan was probably a shield, they didn't dare to contact him rashly, for fear of alerting the real suspect."
"What about Dianzhou?"
"They have contacted the local police station in Dianzhou and asked them to assist in investigating the courier station where the suspect delivered the goods, but they have not received specific results yet."
"It's not efficient." Ding Xifeng sighed, but it is understandable that the police station is not high enough, and it is not easy to apply for an assisted investigation notice. It is also in consideration of this factor that Ding Xifeng asked the second squadron to continue to investigate the source of sales.
"We can't procrastinate any longer, and we must cut through the mess quickly. Everyone, work hard and go on a business trip." Ding Xifeng glanced at the crowd and continued, "Group leader Zhu, you go to Shuzhou, and you go to see the situation in Li Guoshan yourself. , We don't care about it ourselves, and if we don't send people there, the local police naturally can't pay attention to it.
After you arrive in Shuzhou, find out about Li Guoshan's situation and see if he has any connection with the suspect, and then decide whether to make a record or directly bring him under control. "
"yes."
"Wang Xiao, take someone to Dianzhou. Since the goods are sent from Dianzhou, it means that the source of the goods is probably there. Check whether the suspect has a fixed express delivery point. Let's cooperate with each other to see if we can The consignor cannot be lured out."
"good."
"Han Bin, don't worry about Han Shaokang for now, first catch the person who provided Ma Xiaolin with the goods, find a sample of sodium cyanide, and close the case of Chen Zihe being poisoned first.
The case is over, and our pressure will be less. "
"I see."
…
After the meeting, Han Bin arranged the manpower problem.
When Wang Xiao and Zhu Jiaxu went on a business trip, they definitely couldn't be bare-bones commanders, but their funds were limited, so there shouldn't be too many people going there.
After considering the overall situation, Wang Xiao, Jiang Yang, and Zu Dawei went to Dianzhou.
Zhu Jiaxu took He Yingsheng to Shuzhou.
Han Bin led other team members to investigate Ma Xiaolin's case.
After the arrangements were made, Wang Xiao and Zhu Jiaxu went to make preparations, and Han Bin called the other team members for a meeting.
Han Bin glanced at the crowd and said, "Everyone is clear about the situation. Except for the team members who are on business trips, everyone else is responsible for investigating Ma Xiaolin's case. Although Ma Xiaolin has confessed, but the channel for purchasing sodium cyanide has not been found out. One day If the sales channels are not destroyed, more people may be harmed.
Through the interrogation, Ma Xiaolin has given the contact information of the supplier. I am going to lure the snake out of the hole and catch the suspect who provided Ma Xiaolin with cyanide. Everyone can talk about what they think. "
Zhao Ming asked, "Team Han, where are you planning to arrest?"
"It depends on where the suspect will place the transaction." Han Bin responded and asked, "Before that, we need someone to pretend to be a customer to contact the suspect, so I can recommend myself."
Everyone didn't answer.
"Since everyone is so humble, I'll call the roll call." Han Bin glanced at the crowd, and his eyes fell on Li Qin, "Sister Li, why don't you work hard."
Han Bin chose Li Qin for three reasons. The first reason is that Li Qin is a woman, so it is not easy to arouse the vigilance of suspects. Second, based on Han Bin's experience, most of the people who choose to kill by poisoning are women. Third, Li Qin's age is also more appropriate.
Although Huang Qianqian and Feng Na are also women, they are relatively young and have little experience. Generally speaking, Li Qin is more in line with the personality.
Han Bin ordered the general, and Li Qin did not refuse, "Han team, after I add WeChat, what should I say."
"You just say directly that you want to buy a colorless, odorless poison that can kill you instantly, and make an appointment with him as soon as possible."
"I see." Li Qin nodded, took a deep breath, and added the suspect's WeChat account.
The suspect’s WeChat name is Old K.
After adding WeChat, the atmosphere in the office became tense, and everyone was waiting for the suspect's reply.
One minute, two minutes...
Ten minutes passed.
Han Bin glanced at his watch, it's okay to wait stupidly, who knows when the other party will pass
Just when Han Bin was about to say something, 'hum' Li Qin's cell phone rang.
"Team Han, the suspect, Old K, has added me."
"Talk to him."
Li Qin typed, "Are you there?"
Old K, "Yes, who are you?"
"I saw your ad and I want to buy medicine."
"What medicine do you want?"
"I want a colorless, odorless drug that can kill people. It's so powerful that it won't save you even if you send it to the hospital."
"Where are you from?"
"From Qindao."
"Yes, but my medicine is more expensive, so I have to pay first."
"How much?"
"Three thousand."
"What medicine is so expensive?"
"If you think it's too expensive, go buy rat poison. Only fools drink it. You get what you pay for. What I sell is sodium cyanide, which has almost no taste. As long as you eat it, the gods will not be able to save you."
"I really don't have that much money, let's make it cheaper."
"I'm not bargaining."
"Do you think two thousand is okay?"
"The minimum is two thousand and five, and I won't sell anything less."
Li Qin paused before continuing to type, "Okay, then where can I get the goods?"
"Give me the money first, and after paying the money, I will naturally give you the goods."
"I gave you the money, what if you don't give me the goods? I didn't make any sense, you give me the goods first, and I'll give you the money later."
"Let me tell you, we have business all over the world, and we are not deceitful, just like you."
"Then...how can I give you money?"
"You send the money to Guangnan Mall."
"when?"
"You can go over now and put the money in the theater No. 1 on the fifth floor. When I receive the money, I will give you the goods tomorrow."
Han Bin reminded, "I can't do it now, it's too hasty, and there's no time to control it. I'll give you the money tomorrow."
Li Qin sent a message, "I can't do it today, I'm still at work, can I do it tomorrow morning?"
"Can."
"You tell me the exact location, about what time, and I'll take the money over."
"Tomorrow at ten o'clock in the morning, you put the money in Guangnan shopping mall, theater on the fifth floor, cinema hall 1, row 7, row 4. If I remember correctly, it should be Avatar."
"I remember. Then when will I get the goods."
"Wait for the news."
"How will I know which one is you then? What if the money is given to the wrong person?"
"You don't have to worry about what I look like, just put the money under the cushion of the No. 4 chair in the 7th row of the No. 1 theater."
After speaking, the other party stopped contacting.
Han Bin said, "Judging from the current situation, the other party didn't find anything abnormal. Let's go to Guangnan Cinema to control the people who took the money in time."
Han Bin knew that the person who withdrew the money was definitely not the mastermind behind the scenes, and he must be clean and quick when arresting him to prevent him from reporting to the online.
Zhao Mingdao, "Team Han, the trade will only be made tomorrow, so let's go and control them now, isn't it too early?"
"It's not too early, we have to familiarize ourselves with the environment in advance, and install surveillance in hidden places to ensure that when the suspect takes the money, he can get the stolen money."
"It's amazing, but the Han team is thoughtful."
Zhang Shungu said, "Team Han, do you want to say hello to the theater?"
"It is absolutely necessary to say hello, but since the suspect chose the Guang'an shopping mall as the place of transaction, it shows that he is very familiar with the situation there, and it is even possible that he is in the Guang'an shopping mall himself. Let's go to the cinema to investigate and disturb others as little as possible. "
Zhang Shungu said, "Then contact the senior management of the market. The possibility of their involvement in this kind of thing is relatively small, and it is more convenient for us to act."
Li Qindao, "I'll contact the technical department and ask them to help install the surveillance."
Han Bin said, "Yes, you can ask them to prepare the equipment in advance, but the installation will have to wait until midnight."
"The others followed me to the Guangnan shopping mall to familiarize themselves with the shopping mall's environment in advance to prevent accidents during the arrest."
"yes."
Under Han Bin's arrangement, the control work was carried out in an intense and orderly manner
…
In the morning of the next day, Han Bin and others arrived at the Municipal Public Security Bureau early in the morning, and reconfirmed the plan of arresting them.
The mall opened at 9:30 in the morning, and Han Bin and others entered the mall immediately, acting according to the previous deployment.
At 9:45, Li Qin also rushed to the shopping mall. She acted alone to prevent the suspect from being spotted.
When it was time to play, Li Qin immediately sent the suspect a WeChat message, "I'm at the mall."
"Have you brought any money?"
"Yes, I'm about to go to the theater? Where are you, and when will you give me the goods."
"Didn't I tell you that when I get the money, I'll give you the goods. Buy a ticket for Godzilla now, and the show will start at ten ten o'clock."
"Ah, didn't you mean to go to Hall 1 to see Avatar at ten o'clock?" Li Qin frowned. Whether it was surveillance or deployment, the police were all around Hall 1.
"That's a re-screening, it's not good, go see Godzilla, it should be in Hall 3, you put the money under the cushion of chair No. 6 in row 6."
