Lin Lei walked to the inner room and found that there were six bookshelves in the room, except for the wall where the door was installed and there were no bookshelves, and the other three walls were placed with three bookshelves. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The books in the back room are more miscellaneous, mainly newspapers and periodicals.

Inside, Lin Lei saw the nineties version of "Reader", "Bosom Friend", and "Youth Digest" at a glance.

Of course, there are other magazines, of course, which Lin Lei's age is not known.

On the innermost shelf, there are some large books, mainly reference books.

After Lin Lei glanced at the upper room, he returned to the outer room.

According to the file, the owner of the store is surnamed Lu, and the store mainly rents books and magazines, and does not sell books.

After Lin Lei stared at Lao Lu for a long time, he suddenly spoke: "Lao Lu, on the day of the crime, how was the business in the store?"

Lao Lu didn't think about it, shook his head and said, "It's not good." It was too cold that day, and there was very little foot traffic in the alley. ”

Lin Lei nodded slightly, and continued to ask, "How cold is business?"

As soon as Lin Lei's words of inquiry landed, Lu Yun on the side knew very well in his heart that this sentence was very important.

Lao Lu pondered for a moment and replied: "My rental bookstore has a group of regular customers, and they often come to rent books after work. I said that business is not very good, but it is compared to usual, usually I have a full house here. Business wasn't good that day, but the store was still full of customers. ”

Lin Lei asked again coldly: "Old Lu, what time do you close?"

Lao Lu has obviously memorized the lines, and he has been asked by the police countless times: "Ten o'clock." The main customers who rent a bookstore are after work, and my store closes late. There are not many people during working hours, and there will be more talents after work. ”

Lin Lei bowed slightly, turned his head and gave Li Xiaoan a look.

Li Xiaoan understood, took the laptop and found the inquiry record of Lao Lu's bookstore.

The transcript of the interrogation shows that what Lao Lu said is not wrong at all. And some witnesses confirmed that Lao Lu did indeed close the door after 10 o'clock.

"Did you hear any noise in the alley?" Lu Yun asked a little unwillingly.

Old Lu shook his head: "No." I usually have the habit of reading books myself, and I also read books in the store that day to pass the time. ”

In fact, Lu Yun asked the previous police a hundred times, but Lu Yun was worried about what he had missed before, and now it seems that there is nothing missing.

Lin Lei thought about it for a while, and soon left the rental bookstore.

After coming out of the gate, Lu Yun looked at Lin Lei a little nervously: "Lin Lei, how is it?"

Lin Lei smiled slightly, still shaking his head: "It's not good." ”

Lu Yun took a deep breath and looked ahead.

Not far ahead, it is the junction of Pingcang Lane and Hankou Road......

At this time, Lu Yun suddenly saw a telephone pole.

No, of course the pole is not the point, the focus is on the person next to the pole.

An elderly man sits next to a telephone pole with a popcorn stove next to him.

Due to the previous obscuration of the telephone pole, Lin Lei and Lu Yun didn't notice that there were people here when they glanced out of the box in a hurry.

Lin Lei walked up to the old man and looked at his stall.

Popcorn stoves are old-fashioned, black, and not common anymore, but in the eighties and nineties, you can often see popcorn sellers on the streets and alleys like the old people.

Lin Lei still knows the process of popcorn, that is, pouring rice or corn into the stove and then sealing it.

Roast under the stove over a fire, keep turning the stove, and when the heating is complete, there is a loud "boom" and the popcorn is freshly baked.

How did he get it, there seemed to be some trick at that moment, this is not something that Lin Lei can understand, and Lin Lei has no intention of learning this craft.

The fire used in the oven is fueled by the liquefied gas in the liquefied gas tank, which is some distance away from the place where the fire is raised for safety.

According to today's standards, this popcorn method actually uses liquefied gas to ignite an open flame, which must be a dangerous operation and has great safety risks.

But twenty years ago, people's security awareness was not so high, existence was reasonable, and there was nothing to say.

Let's just say that now, there are a lot of snacks made with liquefied gas on the street, and if you really want to talk about safety hazards, you can catch such small traders and vendors anytime and anywhere.

According to the information, the old man who squatted here to sell popcorn was surnamed Tu, let's call him Tu Laohan.

"Lao Tu, when did you set up your stall that day, and when did you close it?" Lin Lei began to ask.

After Lao Tu coughed, he replied: "I came here to set up a stall at six o'clock in the afternoon, and I didn't leave until nine o'clock in the evening." ”

Lin Lei nodded, indicating that he understood.

Back then, popcorn sellers generally haunted at this point in time, after dinner, before going to bed, during this time, there are people in the people's homes, and business will be better.

Because there is a loud bang when the popcorn is popped, people in the neighborhood who are at home hear the noise and know that someone has set up a stall to sell popcorn.

If someone in the family wants to eat it, they will go out and buy it.

If it's a stall in broad daylight on a weekday, and everyone is at work, who will buy it?

Next to Lao Lu's liquefied gas tank, there was a tricycle.

He is a street stall, a "itinerant vendor", and the guy is transported by this tricycle.

Lin Lei walked up to the tricycle and looked at it carefully.

This is a relatively large tricycle, and in order to prevent the liquefied gas canister and popcorn stove from falling during transportation, the baffles around the tricycle are high.

There were also empty burlap pockets in the tricycle, which were used for raw materials, such as rice and corn.

Lin Lei looked at it for a long time, then turned around, stared at Lao Tu and asked, "Lao Tu, do you set up a stall here every day?"

Lao Tu shook his head: "No." I usually come once a week, and popcorn can't be eaten by ordinary people, so it's almost once a week. ”

Lin Lei smiled slightly, and continued to ask: "How big is the scope of your stall's activities, and where is the farthest?"

Lao Tu was stunned for a moment, thought for a while, and gave the answer: "The farthest is only six or seven miles away, basically Qingdao Road and Hankou Road, there are many small alleys here, it is a residential area, and the business is not bad." ”

Lin Lei turned his head and motioned to Li Xiaoan, of course Li Xiaoan understood what Lin Lei meant, and immediately hugged the notebook.

After finding the relevant interrogation records, sure enough, Lao Tu didn't talk nonsense.

His range of activities is within a radius of three kilometers, and he happened to come to Pingcang Lane to set up a stall that day......
