Lao Li said in surprise: "How did you find it?" "That's too fast.

Xu Ran pointed to the balcony and said, "Look at that balcony, is there a lot of things piled up on it with yellow cardboard boxes?" ”

Lao Li looked at Xu Ran's hand, he didn't see it very clearly, and took out an eye cloth from his body to wipe his glasses, Xu Ran looked at the glasses cloth in Lao Li's hand, it was not clean anyway, is this kind of glasses cloth sure to polish the glasses?

Xu Ran felt that it would only get dirtier and dirtier.

Lao Li just put it in his trouser pocket.

Xu Ran was quite speechless to Lao Li.

Lao Li slowly wiped his glasses, took two steps forward, and said to Xu Ran: "There are a bunch of boxes, what's wrong?" ”

Xu Ran said: "If there is a box, it should be the company's warehouse or someone's office." The reason why she thought of this was that she was still on Li Ya's plane, and she moved to rent a house downstairs, which was the warehouse of a small company, and the goods were stacked in it.

She remembers when she was passing by someone's house and saw a camera inside.

She didn't know that there would be offices and warehouses hidden in residential buildings.

But later, after getting acquainted with her neighbors at the time, they told her that renting a house in a residential building is cheap and cost-saving, and offices like this in a residential building are generally engaged in wholesale or online business.

Office buildings are quite expensive.

Xu Ran thought that although it was not a plane, the development situation was still similar, since there was surveillance everywhere, it was impossible to say that there was also one here.

Lao Li nodded, "So you think there might be surveillance in that place?" "It's a good idea.

Xu Ran snorted and said, "Go and try it, no, it won't be delayed for long." ”

Xu Ran is not sure if this place can be monitored, but generally the office or warehouse is installed and monitored.

Like the general commonly used gun type monitoring, hemispherical monitoring, spherical monitoring.

That generally indoor hemispherical monitoring, outdoor gun-shaped monitoring, there are also indoor gun-shaped monitoring, now the general indoor is equipped with hemispherical monitoring, if the opposite is installed such monitoring, it is very likely to shoot the bar door here.

Xu Ran and Lao Li said they would do it, found a place to park the car, analyzed the geographical location, and found the place where the house was located, which was on the second floor.

However, the door of this house was closed, and Lao Li knocked on the door twice and shouted, "Police." ”

The door opened from the inside, and inside was a curly-haired woman, slightly chubby, with a round face, in her thirties, wearing simple white short sleeves and denim shorts, Xu Ran and Lao Li went through another set of processes, and the curly-haired woman looked surprised, police? How could the police come to her, she didn't do anything, did she?

Stretched out his hand to take Xu Ran and Lao Li's documents, took them in his hand and looked at them, and let Xu Ran and the two walk in.

As soon as Xu Ran entered, she looked at the environment of this house, her guess was not wrong, this is a warehouse, doing wholesale of goods, a three-bedroom house, each room is full of goods, and there are two or three people in the living room packing goods.

The room was noisy, with the sound of packing goods tearing tape, and a computer where someone was sitting in front of it, printing out the delivery list, and the dot matrix printer making a 'sting, stinging, stinging, stinging' sound.

Xu Ran said to the curly-haired woman: "Hello, the police are handling the case, is it convenient for us to investigate your surveillance?" ”

"Uh-oh." The curly-haired woman's face was a little hesitant, but she was uneasy in her heart, and after thinking about it, she reluctantly said, "Okay." ”

Xu Ran thanked the curly-haired girl.

Xu Ran walked to the balcony, there was a sliding door from the living room to the balcony, and there was also a monitor in the living room, and there was a monitor in each of the other small rooms, Xu Ran went to the balcony, and sure enough, the balcony also had a monitor.

The place is really narrow, the balcony is full of goods, and Xu Ran can only pass sideways on the balcony to ensure that his body is not next to the cardboard box.

Xu Ran and Lao Li called up the surveillance and found the surveillance on the night of the 29th, but it was disappointing that the surveillance in her hemisphere couldn't shoot the small door of the bar because of the angle problem.

Xu Ran's face was a little disappointed, and he thanked the curly-haired girl.

The curly-haired woman asked, "Where do you want to look?" ”

Xu Ran thought for a while and said, "Just outside, that small alley." ”

The curly-haired woman was silent for a while and said: "This is my warehouse, next door is the office, and there is also monitoring next door, I remember that the camera angle is better than this, because there is no security window next door, so the camera was installed outward, maybe you can find it, I'm not sure." ”

Xu Ran's face was overjoyed when he heard this, and he said, "Thank you, then please take me to see it." ”

Listening to this tone, this curly-haired woman is a boss lady.

Well, it's so kind, if it weren't for this curly-haired woman who said it, she wouldn't have thought that there was an office next door.

The curly-haired woman almost missed it if she hadn't been reminded.

The curly-haired woman took Xu Ran and the others to a house next door, where there were several desks, and two people were sitting in front of the computer typing, Xu Ran and Lao Li investigated the surveillance again.

The gratifying thing is that this surveillance really captured where the small door of the bar is, the video shows that there is a tall and thin man, standing at the small door at half past nine, holding a mobile phone from time to time to look, at nine fifty, the thin man has a mobile phone in his hand, entered from the small door, and came out of it in less than five minutes and closed the door.

After coming out, the man had something in his hand and left the alley directly.

But he couldn't see the man's face clearly, wearing a mask, Xu Ran was not 100% sure that this was Chen Chen.

However, according to the height and body type, as well as the facial contours, it is consistent with Chen Chenting.

Xu Ran looked at the man holding his mobile phone, if this was Chen Chen, then his mobile phone was connected to the surveillance video inside the bar, and he could see the situation inside in real time on his mobile phone.

The deceased surnamed Qu came to the bar at nine o'clock in the evening on the 29th, and the man came at half past nine and should have waited for an opportunity at the door.

Therefore, the time when the man entered through the small door coincided with the time when the deceased surnamed Qu went to the toilet.

Xu Ran sighed, her inference was established step by step.

Although it has not yet been confirmed that the murderer is Chen Chen, it should be eight or nine or ten.

There are really so many unreasonable things in this world, and according to their investigation, Chen Chen and the deceased have no grievances.

They don't even know each other.

Lao Li glanced at Xu Ran, and sighed like Xu Ran, the two copied the video screen, Xu Ran and the curly-haired girl said thank you, and the two went out and left the community.
