Ten o'clock in the morning.

Sun Yaobo and his wife were pressed back to the Yuhua Branch.

The couple had never seen such a battle, and it involved a serial murder case, and they were immediately frightened.

The husband and wife were taken separately into the interrogation room for interrogation.

Han Bin did not participate in the interrogation of the husband and wife again, but started Yang Zhichao's clues.

If Sun Yaobo did not lie, then this suspicion is very high, and it is very likely to be related to a serial homicide.

After Han Bin reported to Ma Jingbo, he began to investigate Yang Zhichao.

First of all, arrange for someone to retrieve Yang Zhichao's correspondence records to see which people are close contacts, most likely his accomplices.

Secondly, investigate Yang Zhichao's information in the public security system to see if it is consistent with what Sun Yaobo said.

Twelve o'clock in the afternoon.

Everyone returned to the office one after another, each holding a bowl of instant noodles, far away.

Ma Jingbo's noodles had just been soaked, and he had to wait a few minutes to eat them, and he glanced at the others, many of them were sucking bubble noodles, and the one they ate was called a fragrant.

Ma Jingbo swallowed his saliva, "While we are eating, let's summarize the case." ”

Zeng Ping was in charge of interrogating Sun Yaobo and his wife, he took a sip of noodle soup and smoothed out, "After the interrogation of the husband and wife, the basic situation has been figured out, Sun Yaobo did not change his words, and still insisted that Yang Zhichao met the characteristics of the suspect." ”

"Personally, I don't think it's very likely that Sun Yaobo lied. ”

Ma Jingbo opened the lid, stirred the instant noodles with a fork, and closed the lid again, "Has Yang Zhichao's situation been thoroughly understood?"

Han Bin got up and walked to the projector and put some information.

Name, Yang Zhichao

Gender, male

Date of birth, March 3, 1995

ID number, 37020XXXXX

Mobile phone number, 13524XXXX

Hometown, Yangma Village, Qingguang Town, Yuhua District, Qindao City

Address, Xinhua District, Room 305, Building 1, Ronghua Shuyuan Community

While everyone was reading the information, Han Bin returned to his table and took another bite of instant noodles.

Yang Zhichao's situation is basically the same as what Sun Yaowei said, Yang Zhichao is a native of Yangma Village, Qingguang Town, not far from Cheng'an Village and Xiaogang Village, so he should be familiar with the situation in that vicinity. ”

"Another one, Yang Zhichao has a white Toyota car under his name, with the license plate number Lu B37XX, which is consistent with the situation of the suspect vehicle. ”

In terms of communication records, Li Hui checked them, and Han Bin glanced at him and motioned for Li Hui to continue.

Li Hui wiped his mouth, "We checked, Yang Zhichao has two mobile phone numbers under his name, of which the mobile phone number starting with 135 has been used for five or six years. There is also a mobile phone number starting with 155 that was handled last year. ”

"Among them, the mobile phone number starting with 135 has many contacts, and it has not been checked for the time being. ”

"The mobile phone number that starts with 155 has only one contact number, and that is the mobile phone number that starts with 135. ”

"It is impossible for the suspect to call himself himself, so I estimate that the mobile phone number starting with 135 may be used by someone else, and the other party may be Yang Zhichao's accomplice. ”

Ma Jingbo nodded, "It seems that this Yang Zhichao is very suspicious, judging from the current clues, he not only provided information about the physical examination center, but may even be a participant in the case." ”

"By the way, how is Yang Zhichao's financial situation?"

Tian Li shrugged her shoulders, "I contacted the banking system, but the bank did not officially work, only a few employees on duty, I urged, but they have not replied." ”

Ma Jingbo snorted, "Keep urging." ”

Ma Jingbo took two bites of instant noodles and continued: "I will arrange a task this afternoon, and Captain Zeng is responsible for investigating the mobile phone number starting with 155 and determining the identity and location of the user as soon as possible. ”

"I'm in charge of investigating Yang Zhichao's line. ”

Subsequently, another personnel assignment was made, and Han Bin, Li Hui, Tian Li, and Zhao Ming followed Ma Jingbo.

Zeng Ping took Wang Xiao, Du Qi, and Sun Xiaopeng to check the mobile phone number starting with 155.

In the end, Ma Jingbo advised, "The task now is to investigate and control, and you are not allowed to arrest people without my orders, understand?"

"Yes. ”

......

After the meeting, there is a small meeting.

Ma Jingbo called Han Bin and the three over, "The basic situation is already clear, what do you think about the next investigation, tell us what you think." ”

"I think we should find out the number of suspects first, so as not to slip through the net. Han Bin said.

This is exactly what Ma Jingbo is worried about, "Let's be specific." ”

Han Bin organized the language, "Let's focus on Yang Zhichao first, and then launch an investigation around him to find out his network and motives for committing the crime, so that we can catch all the suspects." ”

Ma Jingbo thought for a moment, "In this way, Tian Li and Zhao Ming will go to the physical examination center, and you will get in touch with Yang Zhichao to understand his situation and keep an eye on him." ”

"Captain Ma, in what capacity do we contact him? Will it arouse his suspicions, after all, the atmosphere is so tight now, and there are not many people who go for a physical examination. ”

"Let Sun Yaobo arrange, and the two of you will go in the name of applying. ”

Tian Li frowned and said, "Now that many companies are laying off employees, it's not appropriate for us to go for an interview at this time." ”

Ma Jingbo said disapprerovitically, "There is nothing inappropriate, just say that it is a relative of Sun Yaobo's family." Again, other industries are sluggish and layoffs, but the physical examination center belongs to the pharmaceutical industry, not only will it not be affected, but there will only be more people for physical examination in the future, no problem. ”

"Han Bin and Li Hui will go to Yang Zhichao's house with me, let's find out. ”

......

An hour later, Mr. Ma applied for a search warrant and related documents.

He took Han Bin, Li Hui and four police officers from the local police station to the Ronghua Shuyuan community.

Before coming, Ma Jingbo also found a professional locksmith.

Yang Zhichao lives in Room 305, Building 1, Ronghua Shuyuan Community.

According to an employee of the property company, Yang Zhichao was the only one in the family at the time of registration.

However, Han Bin and the others didn't dare to be careless, so they asked the people from the property company to help call the door, but there was no response inside.

Then the lock-picking company is the master, and it takes less than a minute to open the lock.

Ma Jingbo, Han Bin, and Li Hui all carried guns, and no one dared to guarantee whether Yang Zhichao was hiding anyone else in his house.

There's nothing wrong with being careful.

An auxiliary police officer from the police station slowly opened the door, and Ma Jingbo, Han Bin, and Li Hui tiptoed into the house with pistols.

It's a two-bedroom apartment, the living room doesn't have much furniture, only air conditioning, TV, sofa, two coffee tables don't have it, a small square table at the front door of the sofa, and a few beer cans at work.

There are several portraits of male stars on the wall, most of which are domestic fresh meat, and two photos of Hollywood male stars.

Han Bin had a room for the three of them, and when the room was opened, no one was found in the kitchen and toilet.

The door to the master bedroom was open, the curtains were drawn, and a poster of the fruit man hung directly opposite the bed.

For a straight man like Han Bin, it is very spicy.

The door of the side bedroom was closed, Ma Jingbo leaned over and looked in from the crack in the door, the floor tiles were like mirrors, the room was empty, and there was no human figure in sight.

Ma Jingbo pulled the door open, squatted down, held a gun in both hands, and looked at the wall next to the door.

This is a dead end, which cannot be seen through the crack in the door, and the suspect is likely to be hiding here.

Ma Jingbo was lucky, there was no suspect in the house, the whole house was empty, there was not even a cupboard, there was a desk and a chair by the window, "Safe." ”

Ma Jingbo's attention was drawn to a drawing hanging on the wall lying on his side, a skeleton wearing a red cape, holding a scepter in his hand and carving a snake's head.

There is also a mat on the ground in front of the portrait.

After seeing this picture, Han Bin felt very uncomfortable, "What the hell is this?" ”

Li Hui frowned, showing a look of disgust, "This Yang Zhichao can't have any special fetishes, right, he actually has a poster of a fruit man." ”

"Urine. ”
