"And then? What was it like that day? Where did you see the key? I asked.

Xia Ao frowned secretly, and after thinking for a while, he said, "The key is placed on the shoe cabinet." Of course, that's not far from the hook, very close. But in my opinion, that's not normal. So I went to check the lock again and found that there were scratches, which must have been left when the wire was touched. ”

Hearing this, Xiao Liu immediately turned his head and looked at me. And the look in his eyes was very surprised. Because that day, we found that kind of wire in the house of the deceased Chu Juan.

I immediately raised my head, looked at Xia Ao, and asked, "Then you did the thing of stuffing toothpicks in the crack of the door of Chu Juan's house?" ”

Xia Ao generously admitted: "I did it, and I also told Chu Juan." So Chu Juan she knows. ”

I suddenly thought of something, so I secretly lowered my head and arched my ten fingers together, "It means that every time Chu Juan goes home, she will pull out the toothpick and bring it into the house, right?" ”

"Yes, that's for sure." Xia Ao said firmly.

I pondered for a while before asking, "So did Chu Juan tell you about the broken toothpick before?" That is, before the crime, were there any strangers who went to her house and opened the door of her house? ”

"Yes, that's why I gave her my membership card." Xia Ao said.

I asked again, "Then why didn't you choose to call the police at that time?" ”

This time, the Summer Olympics replied: "The police will not accept it." At that time, we reported to the police for the deed tax, but we didn't come here, we were at the nearby police station, but the police there said that we were still playing that kind of game when we were so old. A police officer even said that the reason why the toothpick broke may have been broken by a child passing by. And there was no loss of property at that time, so you can't file a case, right? ”

At this, he paused abruptly, and then added, "One more thing. After that, we actually changed the locks. Especially when I found out that the lock and key in the house had been moved, I changed the lock as soon as possible. I also checked the surveillance video of our community and Chujuan community, but I didn't find the slightest. ”

"Changed the locks? Do you think the murderer knew about this? I asked.

Xia Ao nodded affirmatively and said, "I feel that he should know, because scratches soon appeared on the new lock." I took a picture of the scratch at the time, if you don't believe me, you can look at my phone. ”

Later, we looked at his mobile phone together and found that there were really relevant photos in his mobile phone. From this, he should not be lying.

After reading it, I said, "The murderer may still commit crimes, and he may persecute you." So it may be safer for you to stay in the police station for the time being. We have a responsibility to keep you safe, you have no objection, right? ”

"Nope." He shook his head slowly, "But I want to know, when will you be able to solve the case?" ”

These words immediately silenced me and Xiao Liu.

The two of us turned our heads and looked at him secretly a few times, and then Xiao Liu said, "This case is not so simple. ”

He suddenly had a request: "Then can you let me investigate with you?" ”

"You?" Xiao Liu questioned.

He nodded affirmatively, and looked at me with blank eyes, "Believe me, in this case, I should know more about the murderer than you." ”

Hearing him say this, I immediately turned around and looked at Xiao Liu, wanting to see what Xiao Liu meant.

After a while, Xiao Liu said, "Officer Lu, if he wants to help, I think he might as well let him participate." After all, this case is not so easy to solve, and we can't keep detaining him, right? ”

I was actually worried that he was the murderer.

But if you think about it carefully, even if he is really the murderer, then letting him participate in this case may be able to expose him.

So I nodded cheerfully and agreed.

Once outside, Cheyenne asked, "What were you thinking?" It feels like you're thinking. ”

I smiled faintly, smiling without saying a word.

When I brought him to my office, I said to him, "Sit down, you're welcome." ”

"So this is the deputy director's office!" He seemed to be very envious.

When I saw through it, I asked, "Are you envious?" ”

"Yes, I used to want to be a detective. Of course, in the end, I didn't make it, so I became a private investigator. ”

"Then why don't you be?" I asked.

He turned his head to me, and said with a wry smile, "Because of family relations." My father, who used to be the main culprit in a serial homicide case, was a spicy killer. Alas. Growing up in that environment and wanting to be a police officer? You think too much, and you can't even get into the police academy. ”

For his life experience, I can only look at him with sympathy.

After he walked slowly, he said, "By the way, do you have any opinion on this case?" ”

Hearing me ask, Xia Ao thought about it secretly. Then, he walked over with a big grin, pulled out a chair, and said solemnly: "The murderer is definitely a person with a criminal record." ”

"Where do you see that?" I think he's guessing.

But listening to his analysis, he said: "You think, he will pick the lock, right?" I like to do those petty theft moves. So it's very likely that you have been a thief. And his methods are so clumsy, so I think he should have been arrested before and left a criminal record. And the reason must be the crime of theft, right? ”

"Well, there's a little bit of a point. But there are other possibilities, such as how lucky he is? I asked with a wry smile.

"Come on, if even luck can be counted, then we don't have to reason at all. There are naturally no absolutes in the world, but what I have analyzed is very probable. He affirmed.

Seeing him so confident, I suddenly felt that he was indeed very suitable for this profession.

Just when I looked at him as a person in my heart, I only heard him say, "And it's very likely that he's still single." ”

"Where did you see that?" I asked.

"He followed Chu Juan, not for money, for what?" Xia Ao asked me rhetorically.

"If you are a normal person and don't rob money, then it's very likely that you want to rob something else. But as far as I can see, he is not a normal person in the first place, so he cannot be measured by the standard of a normal person. ”

Xia Ao nodded slightly, "Yes." So what do you think of him? ”

"Me?" I smiled wryly, "I don't have any opinion of him, I have a little bit of you." You are very confident and bold. When chasing you that day, you jumped straight out of the balcony. Really, I know I can't do it. Are you adventurous? ”
