Qin Nan put on rubber gloves and carefully observed the blood stains, and the scene of that night emerged in his mind...
The man in black had been wandering around here since the beginning. After seeing Li Zhong park the car here, he then noticed the big truck. The man in black seemed to have thought of what it was, so he observed the man who had just got out of the car.
Li Zhong,
Later, after Li Zhong returned home, the man in black dragged the body from somewhere, and then accidentally stained the blood on the wall.
"Uncle, have you discovered anything?" Ma Xiaotao came over and asked.
Qin Nan came back to his senses and showed the blood stains on the wall to Ma Xiaotao and others. Wu Fayi came over, smeared the wall with a cotton swab a few times, and then put it into the evidence bag.
Qin Nan couldn't guarantee that the blood stain must be that of the victim. It might have been left by someone else. He could only wait for Wu Fayi's subsequent test results.
"There is a long hair here." Wu Haotian picked up a long hair on the ground and said. The length of the long hair seemed to be the same as the hair on the big truck.
Qin Nan recalled the surveillance video in Officer Zhao's police station. The large truck in the video seemed to be traveling a bit slowly. Just as the contractor Shi Jie said,
Even if it is a manual transmission driver driving a large truck for the first time, he must be a little unfamiliar with the things above, and the large truck in the surveillance video seems to be driving a bit slowly.
When turning around, it took almost a minute to successfully turn around.
At this time, Qin Nan suddenly thought of something, so he quickly took out his mobile phone and called Song Yi:
"Hey, Lao Song, are you okay now?"
"What's wrong? Your voice sounds a little anxious." Song Yi asked doubtfully.
"Well, ask He Shizhu where he met the person who gave him the explosives that night." Qin Nan said.
"Okay, I'll tell you the results later." Song Yi said and then hung up the phone.
Qin Nan and the others were near Jinyuan Road in Yubei District, which was about six or seven kilometers away from Xinglong Street where the explosion occurred. It was also about six or seven kilometers away from where He Shizhu and the others lived.
About ten minutes later, Qin Nan's mobile phone received a message with only three words sent by Song Yi - Binjiang Road.
The corner of his mouth raised slightly, and then he motioned for several people to get into the police car. After sending Li Zhong back to the construction site, they rushed back to Officer Zhao's police station.
Several people checked the surveillance again. This time they had a clear direction of investigation. They called out the surveillance of Binjiang Road where the big truck was parked, Jinyuan Road where the big truck was parked, and Xinglong Street where the explosion occurred.
As expected, the man in black appeared in these locations.
Wu Fayi also analyzed the collected DNA, and sure enough, these were the victims.
After a series of investigations, we discovered the community where the man in black lived, Qingde Community.
The community is only a few hundred meters away from the barbecue street on Jinyuan Road. Qin Nan and the others quickly locked the target. At this time, it was already 4:30 in the afternoon, and in half an hour it would be the rush hour for get off work. .
Several people hurriedly left the police station and came to the vicinity of Jinyuan Road again in the police car. Qin Nan signaled Wu Haotian to park the police car in an underground garage a few hundred meters away to prevent the murderer from noticing the police car and be more vigilant.
Qin Nan saw that several people were wearing police uniforms, so he said to the three of them: "Just wait for me in the car. It's not convenient to wear police uniforms. I will call you as soon as there is news."
"I'll go with you." Wu Haotian said as he took off his outer coat, leaving only a thin sweater.
"Forget it, there's really no need. It's not convenient for two people to work together. Fa Yi, give me the simulated portrait." Qin Nan said.
"Okay, be careful on the road and send us a message if you notice any danger." Wu Fayi handed the simulated portrait to Qin Nan.
Several people looked at the direction Qin Nan left and couldn't help but sigh.
"It seems that I have to prepare a plainclothes jacket at all times." Wu Haotian said...
Qin Nan left the underground garage, put on a mask, and walked a few hundred meters to the door of Qingde Community.
He looked at his watch. It was exactly five o'clock in the afternoon, but there were not many pedestrians at the gate of the community.
This community looks very ordinary, similar to the Wenhua Community a few months ago. It has been a bit older.
Qin Nan looked at the security booth on the side. Sitting inside was an uncle wearing a coat and glasses. He looked to be in his fifties.
He hurriedly walked towards the security booth, handed the simulated portrait in his hand to the uncle and asked: "Uncle, do you know this person?"
The uncle stroked the glasses on the bridge of his nose, looked at Qin Nan and then at the simulated portrait, and said calmly: "We know each other, what's wrong?"
What Qin Nan didn't expect was that the uncle actually knew the woman in the portrait. This was an unexpected surprise, so he asked: "Uncle, do you know which building she lives in? How many people are there in the family?"
"
The uncle turned his back on Qin Nan, as if he didn't want to talk to her: "Who are you? You just come to find someone with a picture. Are you the owner of this community? How many buildings and units do you live in?"
Qin Nan sighed helplessly and said, "Uncle, I'm from the criminal police team of the city bureau. I have something to ask about this family."
"From the City Bureau's Criminal Police Team?" The uncle looked Qin Nan up and down again, a little unconvinced. He looked like a jobless bum no matter what.
"You say it is, what proof do you have?" the uncle asked.
Qin Nan doesn't have proof of this, and he doesn't have a work permit or anything like that, because he is just a consultant. Although he works in the police station, it is all Song Yi's salary, so there is no proof.
If you want to prove your identity, you have to ask Ma Xiaotao and the others for help, but at this time they are wearing police uniforms and it seems a little inconvenient to enter the community.
At this time, Qin Nan thought of a way. He made a video call to Ma Xiaotao and asked her to talk to the uncle for a long time before the uncle believed Qin Nan's identity.
"I don't know this woman..." the uncle said after taking the portrait. Just when Qin Nan wanted to curse, the uncle continued:
"However, the staff at the property management department have their detailed information. You can go there and ask..."
Qin Nan rolled his eyes inadvertently, squeezed out a smile and asked: "Uncle, why did you say you knew her..."
The uncle looked upward at a 45-degree angle and recalled: "It's like this. The woman in the photo and her husband quarreled at the gate of the community that day because the husband didn't help her carry the things in her hand.
Later, the woman threw everything in her hand on the ground, and all the eggs in the bag were smashed. Later, the man walking in front noticed and slapped the woman on the face.
I saw more and more people around, and then left the scene, leaving only this woman crying at the door, so I was quite impressed.
The property management side should know their situation. Just tell them about the couple who had a quarrel at the door a week ago. They will know about it because a little sister from our property management company sent her home at that time."
"Okay, thank you, uncle." Qin Nan took the simulated portrait and walked towards the property management office.
As soon as Qin Nan came to the property management office, he directly identified himself, and the staff here quickly believed that he was a police officer.
He handed the simulated portrait to one of the staff. The staff looked at it for a long time and thought it looked familiar. Later, Qin Nan said that it was the couple who had an argument at the door a week ago.
The real estate agent sitting in the corner remembered that woman.
"I know who this person is. Her name is Zhu Shuhua. She is thirty-nine years old. I sent her back that day. After I talked to her, she said without hesitation that she had depression and felt a little impatient.
She just suffered from depression recently, and I don’t know the specific reason,” the property manager said.
"Do you know which unit, floor and number she lives in?" Qin Nan asked.
The property staff member flipped through his notebook, then pointed to the building facing him and said, "This is the building, Building 2, 13-1."
Qin Nan looked in the direction the woman was pointing and asked, "How many people are there in their family?"
She turned over the information in her hand and said: "There are two people in their family. The man's name is Chu Tianyi, and the woman's name is Zhu Shuhua. I heard from Sister Zhu that her husband is a university teacher, teaching physics and chemistry. As for Sister Zhu, she is a
