"Da da da …"
A rush of footsteps could be heard, and Han Bin couldn't help but frown.
The sound came from below the stairs.
Before Han Bin entered the stairs, he had already ordered the police to keep an eye on the stairs. If any outsiders entered, the other party would definitely warn them.
Bao Xing glanced through the crack in the stairs, "It's Team Leader Zhu."
It wasn't hard to understand. The transportation line was originally investigated by Zhu Jiaxu, but in the end, Han Bin took the initiative to investigate Niu Xin.
Zhu Jiaxu inevitably felt a little uncomfortable.
Where there are people, there will be competition. This competition may come from outside the organization, or it may come from within the organization.
Competition will maintain the vitality of an organization, which is a good thing to a certain extent.
Of course, the premise is that there is a healthy and controllable competition.
Zhu Jiaxu ran to the front and asked while panting, "Han Bin, what's the situation? Did you find Niu Xin's trace?"
Han Bin smiled. "There's no rush. Let's catch your breath first."
Zhu Jiaxu waved his hand, pointed to the iron door, and said softly, "It's okay, is this where Niu Xin rents?"
"Yes."
"Is he at home?"
Han Bin said, "I called the door, but no one responded."
"Let's go straight to the locksmith company." Zhu Jiaxu suggested.
"I've already asked someone to contact them." Han Bin replied. At present, this was indeed the safest choice.
Not long after, the locksmith company arrived. Han Bin showed his ID and asked the locksmith to help open the door.
Jiayuan District was an old-fashioned neighborhood, and the lock was also relatively old. The locksmith easily opened the door and quickly retreated to the side.
Seeing the police's lineup, he was also afraid. What if there was a vicious criminal behind the door who came out and shot him? Who could he go to reason with?
If the Public Security Bureau didn't pay, his wife and daughter would have to live a hard life.
If the Public Security Bureau lost money, his wife and daughter's money would also become someone else's.
Naturally, Han Bin and the others didn't understand the locksmith's thoughts.
As soon as the door opened, Zhu Jiaxu took the lead and rushed in.
Zhu Jiaxu naturally had his merits as the leader of the Criminal Investigation Brigade of Qingdao City. At least, he had the courage to fight.
"Safe!"
"Safe!"
"Safe!"
…
The team members who were searching the room issued commands one after another.
It was an old-fashioned two-bedroom apartment with an estimated floor area of sixty to seventy square meters. However, the shared area of this kind of house was relatively small. Some people just liked this kind of old-fashioned two-bedroom apartment.
There was no trace of Niu Xin in the house.
Han Bin stood in the living room and looked around. After making sure it was safe, he put away the gun.
Zhu Jiaxu was a little disappointed. "It was a false alarm."
Han Bin smiled. "It's better than exchanging gunfire with the suspect."
Zhu Jiaxu said, "I can't wait to arrest the suspect. It's better than investigating like a headless fly."
Han Bin called Ma Jingbo's cell phone and reported the situation to him.
Zhu Jiaxu contacted the technical department and asked them to send someone to investigate the scene.
After the report, Han Bin had nothing to do, so he began to carefully examine the scene.
The first search of the house was only to check for danger and relatively clear clues. There would only be a second, third, or even fourth investigation of the scene to avoid missing out on important clues.
In order to avoid damaging evidence, most of the police officers went outside, leaving only a few police officers from the city's criminal investigation department in the house.
Han Bin put on his shoe covers and gloves and began to carefully examine the room.
Han Bin's first impression was that the house was very clean. It was abnormally clean. Either no one lived in it for a long time, or it had been cleaned.
From the dust on the table, the first possibility was unlikely.
The room looked more like it had been cleaned.
Han Bin contacted the owner of the house through the local police station.
Hearing that something had happened to his house, the landlord rushed over in a hurry.
As soon as he entered the door, he panted and shouted, "Officer, this house is mine. What happened?"
Han Bin looked at him. He was a middle-aged man in his forties, wearing a half-rimmed glasses. "You came quite fast."
"Yes, I live nearby. The two houses are not far apart."
"What's your name?"
"Song Zhi."
"Take out your ID, house book, and rental contract."
"I brought them all." Song Zhi took out the documents from his bag and passed them to Han Bin.
Han Bin first checked the ID and compared it with his own. Then, he checked the house book and checked the apartment building and room number.
Finally, Han Bin checked the rental contract.
The person who rented the house was Niu Xin himself. He also used Niu Xin's ID and signed his name.
Han Bin pointed at the photo on the ID. "Is he the one who rented the house?"
"Yes."
Han Bin asked, "Is there anyone else with him?"
Song Zhi thought about it and shook his head. "No, he's alone."
"There's only this rental contract. There's no other information about the community," Han Bin said.
Song Zhi took the rental contract and flipped through it. "No, I've always rented like this. I've asked my friend who's an intermediary. It's legal."
Han Bin snorted. "Then do you know how old Niu Xin is this year?"
Song Zhi was puzzled. "I don't care how old he is. What does this have to do with renting a house?"
Han Bin poked at the ID copy. "Answer me after you see it clearly."
Song Zhi looked at the direction Han Bin was pointing at and mumbled, "Date of birth, 2003 …"
"What the f * ck, this kid is still underage."
Bao Xing said with a straight face. "You rented a house to a minor without any information from the community and no parents accompanying him?"
"I, I … That kid is tall and sturdy, he's even taller than me. How would I know that he's underage? I'm really wronged." Song Zhi cried out with a sullen face, "If I knew that I would get into trouble, I wouldn't have rented it to him even if you beat me to death."
"Police comrade, what crime did that kid commit to make you mobilize such a large force? My house isn't affected, right? "
Han Bin ignored him and ordered Jiang Yang and Bao Xing to take down his statement.
However, the evidence provided by the landlord Song Zhi proved one thing. This could be another crime scene.
Because Niu Xin used his ID to sign the rental contract, even if he cleaned up all his fingerprints and DNA, the police would still know he was here.
If Niu Xin cleaned up the scene, then his purpose should not only be to cover his tracks. With the rental contract, he couldn't cover it up.
Then, he cleaned up the scene. It was likely that he had done something illegal here, so he cleaned up the scene.
The second hypothesis was that if Niu Xin did not clean up the house, then someone else did it.
According to the existing evidence, Han Bin boldly guessed that the person was likely to be the mastermind behind the scenes.
Then, Niu Xin was most likely dead, and this was most likely the crime scene.
Based on the above speculation, the possibility of this being a crime scene was very high.
It was difficult for the criminal investigation team to find criminal evidence from a cleaned up scene alone.
Everyone had their own specialties, and this kind of work still had to depend on the technical department.
…
Ten minutes later, the technical team arrived at the scene.
This time, Ma Xiwen from the technical department was in charge of investigating the scene.
Ma Xiwen looked like he was in his thirties, wearing thick glasses. He was already balding, which made him look even older.
"Old Ma, why are you so slow? You only came now?" Zhu Jiaxu complained.
"I wanted to come earlier. I have a lot of work on my hands, and I have to hand it over." Ma Xiwen said as he put on his gloves. "Unrelated people, please leave the scene first."
Although he used the word "please", it was obvious that he was chasing people away.
Han Bin went downstairs with his men, took out a pack of cigarettes, and distributed it to everyone. He lit the cigarettes and smoked.
Compared to staying upstairs, he preferred to smoke here.
"Han Bin, what do you think is the situation now?" Zhu Jiaxu also came over.
Han Bin threw him a cigarette. "Wait and see. I believe the technical department will find something."
Zhu Jiaxu lit the cigarette and didn't bother to smoke. "Do you think this is a crime scene?"
Han Bin puffed out a smoke ring and stretched. "It's very likely."
"F * ck, this case is really full of twists and turns." Zhu Jiaxu took two deep puffs of his cigarette and revealed a thoughtful expression.
"Woo woo …" Just then, a car drove into the neighborhood.
Han Bin glanced at it. It looked familiar.
It was probably Ma Jingbo.
Sure enough, the car stopped nearby. Ma Jingbo walked out of the driver's seat and was stunned. "D * mn, I just finished my work and rushed over. You two are so relaxed."
Han Bin smiled and passed a cigarette to Ma Jingbo. "The technical department is upstairs. We'll just cause trouble if we stay there."
Ma Jingbo took the cigarette and didn't bother to smoke. "How's the situation?"
Han Bin shrugged. "I've reported everything I know to you through the phone. Now, we're just waiting for the technical department to investigate the scene."
"Captain Ma, where have you been? You haven't been seen for a long time. It's not like you," Zhu Jiaxu said.
Ma Jingbo lit his cigarette and said calmly, "What else can I be doing? If it's not investigating, it's a meeting. If I could come, I would have come long ago."
Zhu Jiaxu laughed. "What meeting? What instructions did the higher-ups give us? Did they give us a raise or benefits?"
Ma Jingbo snorted. "Next time, when you're dreaming, don't talk nonsense in broad daylight."
Zhu Jiaxu laughed.
While they were talking, a person came out of the stairs. It was Ma Xiwen from the technical department.
"Captain Ma, you're here too."
Ma Jingbo extinguished his cigarette and walked up to him. "Xiwen, did you find anything?"
Ma Xiwen nodded. "Yes."
"What did you find?"
Ma Xiwen kept him in suspense. "You're an experienced criminal investigator. Follow me upstairs and you'll understand without me saying much."
"Let's go." Ma Jingbo responded and led Han Bin and the others upstairs.
Han Bin stepped into the house again and smelled a strong medicinal smell. It was a bit similar to the smell of disinfectant, but it was a little different when he smelled it carefully.
The living room was dark and the curtains were drawn. The floor and the coffee table emitted a bluish-purple fluorescence …
