"Da da da……"

A rush of footsteps sounded, and Han Bin frowned involuntarily.

The voice came from below the corridor.

Before entering the corridor, Han Bin had instructed the police to stare at the entrance of the corridor. If an outsider enters, he will definitely warn him.

Bao Xing glanced through the crevices of the stairs, "It was Team Leader Zhu who brought the people here."

It's not difficult to understand. Zhu Jiaxu originally checked the transportation line, but Han Bin found Niu Xin first.

Zhu Jiaxu will inevitably feel a little uncomfortable.

Where there are people, there will be competition. This competition may come from outside the organization or from within the organization.

Competition will maintain the vitality of an organization, which is also a good thing to some extent.

Of course, the premise is controllable healthy competition.

Zhu Jiaxu ran to the front and gasped and asked, "Han Bin, what's the situation? Have you found Niu Xin's trail?"

Han Bin smiled, "Don't be in a hurry, first breathe well."

Zhu Jiaxu waved his hand, pointed at the iron gate, and said softly, "It's okay, is this the place where Niu Xin rented?"

"Yes."

"Are people home?"

Han Bin said, "I called, no one responded."

"Look to the unlocking company directly." Zhu Jiaxu suggested.

"I've been contacted." Han Bin replied, so far this is indeed the safest choice.

Before long, the people from the unlocking company arrived, and Han Bin showed his credentials and asked the unlocker to help open the door.

Jiayuan Community is an old-fashioned community, and the door locks are relatively old. The unlocker easily opened the door, and then quickly stepped aside.

He was also afraid of seeing the police, if there was a vicious gangster in the door, he would come out and shoot himself, where would he be reasonable?

If the Public Security Bureau does not lose money, the wife and daughter will have to live a hard life.

If the Public Security Bureau loses money, the money of the wife and children will become other people's money, making them even more embarrassed.

Naturally, Han Bin and others did not understand the careful thought of the master unlocker.

As soon as the door opened, Zhu Jiaxu took the lead and rushed in.

Zhu Jiaxu's ability to become the leader of the Qindao City Criminal Investigation Brigade naturally has his advantages. At least he can do it if he dares to fight.

"Safety!"

"Safety!"

"Safety!"

...

The team members who searched the room issued a series of commands.

This is an old-fashioned small two-bedroom, estimated to have a construction area of ​​60 or 70 square meters, but this kind of house has a small pool area. Some people prefer this old-fashioned small two-bedroom.

No trace of Niu Xin was found in the room.

Han Bin stood in the living room, glanced around, and after confirming his safety, he put away the pistol.

Zhu Jiaxu was a little disappointed, "a false alarm."

Han Bin smiled, "It's better than shooting at the suspect with a gun."

Zhu Jiaxu said, "I'm so eager to take down the suspect directly, it's better than investigating like a headless fly."

Han Bin called Ma Jingbo's cell phone and reported to him.

Zhu Jiaxu contacted the technical department and asked them to send someone to investigate the scene.

After the report, Han Bin stayed idle and began to check the scene carefully.

The first time the house was searched was only for danger and clearer clues. Only a second, third, or even fourth time to investigate the site would be conducted to avoid missing important clues.

In order to avoid destroying the evidence, most of the police officers went outside, leaving only a few police officers from the city criminal investigation brigade in the house.

Han Bin put on shoe covers and gloves, and began to check the room carefully.

Han Bin’s most intuitive feeling is that the house is very clean, and it’s a bit abnormal. It has either been unoccupied for a long time or has been cleaned.

Judging from the dust on the table, the first possibility is unlikely.

The room is more like it has been cleaned.

Han Bin contacted the owner of the house through the local police station.

Hearing that something happened to his house, the landlord rushed over in a hurry.

As soon as he entered the door, he shouted out of breath, "Comrade Police, this house is mine. What's wrong?"

Han Bin took a look at the other person. He was a middle-aged man in his forties, wearing half-rim glasses. "You came very quickly."

"Yes, I live near here, the two houses are not far apart."

"What is your name?"

"Song Zhi."

"Take out your ID card, house book, and lease contract."

"I'll bring them all." Song Zhi took out the documents from his bag and handed them to Han Bin in a brainstorming manner.

Han Bin first checked his ID card and compared it with himself. Then he checked the room book and checked the unit building and room number.

Finally, Han Bin checked the lease contract.

The renter was Niu Xin himself, and he used Niu Xin's ID card, and the signature was also written by Niu Xin.

Han Bin pointed to the photo on his ID, "Is he the rented house himself?"

"Yes."

Han Bin asked, "Are there anyone else to accompany you?"

Song Zhi thought for a while, and shook his head, "No, he is alone."

"There is only this lease contract and no other community information." Han Bin said.

Song Zhi took over the lease contract and flipped through it, "No, I have always rented like this. I asked a friend who is an intermediary, it is legal."

Han Bin snorted, "Then do you know how old Niu Xin is this year?"

Song Zhi was a little puzzled, "I don't care how old he is. What does this have to do with renting a house."

Han Bin poked his finger at the photocopy of his ID, "I will answer after seeing it clearly."

Song Zhi looked in the direction of Han Bin's fingers, and muttered, "Date of birth, 2003..."

"It's a dog, this kid is not an adult yet."

Bao Xing said sternly, "Without the community's filing materials and without the company of your parents, you would rent the house to minors?"

"I, I... that kid is five big and thick, taller than me. I didn't know he was underage. I was really wronged." Song Zhi cried out cryingly, "I knew it would cause trouble. give him."

"Comrade police, what the **** did that kid commit to make you so excited. My house has not been affected."

Han Bin ignored him and ordered Jiang Yang and Bao Xing to make a transcript for him.

However, the evidence provided by the landlord Song Zhi proves one thing, and this is probably another crime scene.

Because Niu Xin used his ID card to sign the lease contract, the police knew he had been there even if he had cleaned up all his fingerprints and DNA.

If it was Niu Xin who cleaned the scene, then his purpose of cleaning the scene should not only cover his whereabouts, he could not cover up with the lease contract.

Then he cleaned the scene, probably because he did other illegal and criminal things here, so he cleaned the scene.

The second hypothesis is that if Niu Xin did not clean the house, it was the house cleaned by others.

Based on the available evidence, Han Bin boldly guessed that the person was probably behind the scenes.

So, Niu Xin is probably already ill-fortuned, and this is probably the scene of the crime.

Based on the above speculation, it is very likely that this is a crime scene.

It is difficult for the criminal investigation team to find criminal evidence from the cleaned scene.

There is a specialization in surgery, and this kind of work depends on the technical department.

...

Ten minutes later, the technical team rushed to the scene.

This time, it was Ma Xiwen from the technical department who was in charge of the site survey.

Ma Xiwen looks in his thirties, with a thick spectacle frame, already a little bald, making him look older.

"Lao Ma, why are you so slow, come here now." Zhu Jiaxu complained.

"I want to come early. I have to hand over a lot of work." Ma Xiwen said, putting on his gloves, "Please leave the scene first."

Although I used the word "please", it was clear that I was rushing people.

Han Bin took the people downstairs directly, took out a box of cigarettes and divided them among the people, lit the cigarettes, and started smoking.

He is more willing to smoke a cigarette here than staying upstairs.

"Han Bin, what do you think is the situation now?" Zhu Jiaxu also leaned over.

Han Bin threw him a cigarette, "Wait, I believe the technical department will find it."

Zhu Jiaxu lit a cigarette and ignored it. "You think this is a crime scene."

Han Bin spit out smoke rings and stretched, "It's very likely."

"It's coming, this case is really tortuous." Zhu Jiaxu took a couple of cigarettes, showing a thoughtful look.

"Woo..." At this moment, a car drove into the community.

Han Bin glanced, familiar.

It is estimated that Ma Jingbo has arrived.

Sure enough, the car stopped nearby, and Ma Jingbo walked out of the driver and was taken aback for a moment, "Sister, I just rushed over when I finished my business. You two are quite leisurely.

Han Bin smiled, and handed Ma Jingbo a cigarette, "The people in the technical department are on it, so it's a mess for us to stay there."

Ma Jingbo took the cigarette, but didn't care about it. "How is the situation?"

Han Bin shrugged, “I’ve reported everything I know about on my mobile phone. Now I’m waiting for the technical department to survey the scene.”

"The horse team, where did you go? I haven't seen anyone for a long time. It doesn't fit your style." Zhu Jiaxu said.

Ma Jingbo lit his cigarette, and said, "What can I do? It's not an investigation or a meeting. I can come early."

Zhu Jiaxu smiled and said, "What meetings are being held, and what instructions are there, whether to increase the wages of the grassroots or give us benefits."

Ma Jingbo hummed, "Dreams at night in the future, don't always talk nonsense in broad daylight."

Zhu Jiaxu smiled.

During the conversation, a person came out of the stairs, it was Ma Xiwen from the technical department.

"The horse team, you are here too."

Ma Jingbo pinched out the cigarette butt, stepped forward and asked, "Xiwen, have you found it?"

Ma Xiwen nodded, "Yes."

"What found?"

Ma Xiwen sold it off, "You are an old criminal investigator, follow me up and have a look, you don't need to say more to understand."

"Let's go." Ma Jingbo replied, leading Han Bin and others upstairs.

Han Bin stepped into the house again, and he smelled a strong smell of medicine, which was a bit similar to the smell of disinfectant, but it smelled differently.

The living room is dark, the curtains have been drawn, the floor and the coffee table are glowing blue and purple fluorescence...
