Next, Lin Lei stopped in front of the courtyard where Liu Hongjun and Bai Guilan lived. Pen "Fun" Pavilion www.biquge.info

Officer Wang had already known that Lin Lei's reasoning had targeted the murderer at the category of "traders".

Liu Hongjun, Bai Guilan and Liu Cheng are residents of Pingcang Lane, and they are obviously not merchants......

Just as Officer Wang was about to move forward, he heard Lin Lei speak.

Lin Lei said something earth-shattering!

"The victim Ai Qing, walked into this yard on the day of the crime!"

"Ahh

Officer Wang exclaimed!

Bai Guilan, who was standing in the courtyard, also exclaimed!

Liu Hongjun and Liu Cheng sat directly on the ground and collapsed......

Officer Wang immediately gave an order, and several policemen who followed him immediately rushed into the courtyard and controlled Liu Hongjun and others.

"I'm not a murderer!" Liu Hongjun shouted after coming back to his senses, with an innocent expression.

Bai Guilan frowned, lowered her head, and didn't say a word.

And Liu Cheng was stupid and in a state of complete confusion.

As soon as Officer Wang saw Bai Guilan's expression, he immediately knew that the murderer was most likely her!

If the murderer wasn't her, why didn't she argue?

At the very least, it should be frightened, right?

What does it mean to bow your head and be silent?

"Superintendent Lin, are the murderers really them......? You said that the murderer was an acquaintance of Ai Qing who knew a certain amount about him, but Ai Qing had no reason to enter this courtyard!"

"Of course there is a reason!" Lin Lei hadn't spoken yet, but Lu Yun spoke first.

Lin Lei smiled slightly, nodded, and motioned for Lu Yun to continue.

Lu Yun had analyzed with Lin Lei before, and she thought that if Ai Qing really disappeared in the Closing Alley, then Ai Qing took the initiative to walk into a certain place at that time - it could only be Bai Guilan's yard!

At that time, Lin Lei was noncommittal about Lu Yun's statement, and now it seems that Lin Lei agrees with Lu Yun's reasoning.

Lu Yun took a deep breath and explained: "To analyze where Ai Qing walked in, we must analyze it in combination with the specific situation on the day of the crime, rather than guessing randomly. ”

Before Ai Qing left the dormitory that day, he was a little unhappy with his classmates in the same dormitory. The girl who shared the dormitory with Ai Qing that day was found to be using an induction cooker illegally, and the teacher asked for an equal share of the fine, Ai Qing was the head of the dormitory at the time, and it was obvious that the atmosphere of the day was not so harmonious.

Ai Qing left the dormitory after dinner, and before leaving, she spread the quilt on the bed.

This means that she planned to come back that night, but not soon.

The detail of laying the quilt said that she estimated that the time she would go out was at least between one and two hours. Because if it was only delayed for half an hour, Ai Qing would not have laid the quilt. Since she had spread out the quilt, she would not be back until at least 8 o'clock.

Of course, Officer Wang knew this situation very well, he frowned and said: "So our police suspected that Ai Qing had an appointment with an acquaintance at that time, and then focused on investigating Ai Qing's acquaintance, but found nothing. ”

Lu Yun glanced at Liu Hongjun, who was caught by the police, and said coldly: "If I'm not mistaken, you're a carpenter, right?"

Liu Hongjun was sweating profusely, and his face suddenly turned the color of pig liver.

Officer Wang looked at Lu Yun with some puzzlement, and asked, "Officer Lu, what's wrong with the carpenter? What connection can Ai Qing have with a carpenter?"

Lu Yun glanced at Liu Hongjun and said slowly: "Ai Qing was expected to go out for about two hours that day, but the police investigated her acquaintances on a large scale afterwards, but there was no result, which shows that Ai Qing is not going to meet acquaintances in the traditional sense." ”

After a pause, Lu Yun continued: "On that day, someone in Aiqing's bedroom used electricity in violation of regulations, and everyone was fined for this. As the head of the dormitory, Ai Qing will definitely find a way to solve the problem of 'illegal electricity use'!"

When Officer Wang heard Lu Yun's words, he couldn't help but nod again and again: "Well, it makes sense." Previously, everyone also had various speculations about Ai Qing's whereabouts, and there were all theories, but they were all subjective speculations, and there was no objective evidence to support them. What does Officer Lu mean Ai Qing is going out, is he trying to find a way to solve the problem of illegal electricity use?"

Lu Yun said softly, and then said: "The plug-in board in the bedroom is open, and anyone can plug in the electrical appliances to use it, so it leads to the illegal use of induction cookers. If you want to solve this problem, there is only one way, lock the power strip and make the power strip no longer available to anyone!"

"How do you lock the power strip?" Officer Wang frowned, a little puzzled.

Lu Yun smiled slightly, and glanced at Liu Hongjun meaningfully: "It's very simple, such as finding a carpenter to make a wooden box and adding a lock on the outside." It was locked up during class, and everyone went back to the dormitory and opened it again. The person who secretly used the induction cooker that day used it when no one else was in the dormitory. Making a simple wooden box lock can solve this problem. ”

As soon as Lu Yun's words landed, Officer Wang suddenly realized, and slapped his face: "Officer Lu really woke up the dreamer with a word, it turns out that the truth is like this!"

Lu Yun's eyes stared at Liu Hongjun like a knife, Liu Hongjun's whole body shook violently, and he didn't know what he was talking about.

Bai Guilan, who was beside Liu Hongjun, sighed and said weakly: "Alas, it's all my fault...... I said, I say it all...... But that little girl really wasn't killed by us!"

Lu Yun glanced at Lin Lei, but saw that Lin Lei was expressionless, so he turned his head to Bai Guilan and said, "Say, what's going on!"

Bai Guilan exhaled a long breath, stabilized her mind, and said: "Back then, my brother-in-law Liu Hongjun was a carpenter, and in addition to working on the construction site, he would also take on some neighbors' work. For example, someone's stool is broken, the table is lame, making a small carpentry object, etc. ”

Lu Yun frowned slightly, and asked, "Was there a sign at the door of your house at that time?"

Bai Guilan nodded: "Well, there is a sign of 'Carpenter Liu' hanging at the gate of the courtyard." ”

"You continue—" Lu Yun's brows furrowed even tighter.

Next, Bai Guilan began to recall the situation of the day.

In the evening of the day of the crime, a little girl in red walked into the courtyard and asked if anyone could do carpentry here. Ai Qing then introduced himself as a student at Dongfang University and wanted to make a wooden box for the power strip in the dormitory, which was locked on the outside.

This kind of small carpentry work is what Liu Hongjun is good at, so Bai Guilan accepted it in one bite.

Presumably, there is a sign of "Carpenter Liu" hanging at the door of this household, so Ai Qing will come to the door......
