Leng Tong and I saw in the crack of the bedroom door that Aunt Chen took the water and went upstairs while sprinkling water on the stairs, Zhuang Sheng also closed the door and returned to the bedroom, looked at us, and hung his head silently.

I stared at Zhuang Sheng for a while, and said slowly: "Zhuang Sheng, what do you know, I can't help but say it now, it's already three lives, if you are still obsessed, the next one is you, there is no doubt about it, you better tell us as soon as possible." ”

Zhuang Sheng also raised his head to look at me, and quickly shook his head and said, "I don't know anything, and I don't have anything to tell you, so don't ask me." ”

Leng Tong looked at me, turned his head to Zhuang Sheng and said, "If someone knocks on the door in a while, don't make any more noise, we will wait in the bedroom, the person who killed you will come soon." ”

I understand what Leng Tong means, although this Zhuang Sheng doesn't say it now, but after a while, the murderer came, and the technical unlock came in and was captured by us, and he couldn't escape, so he was brought back to the police station for interrogation at that time.

We didn't ask Zhuang Sheng anymore, just waited in Zhuang Sheng's bedroom, and it could be seen that Zhuang Sheng was also very nervous, looking up at the two of us from time to time, and then lowered his head.

After less than half an hour, my phone rang, I was slightly stunned, and then answered: "Brother Lei! ”

"Xiaoxiao, you can really reason!" Da Leizi said with a smile: "I'll find someone to test it after I go back, those two bottles of drinks really have sleeping pills in them, Li Yan can't run away, haha!" ”

Leng Tong also came over to listen, with a look of joy on her pretty face, Da Leizi was right, no matter whether the other murderer could be caught or not, Li Yan would not be able to escape.

"Xiaoxiao, can I still go up?" Da Leizi asked, "Has the murderer gone?" ”

"Not yet, you don't have to come up." I thought about it and said: "It's not completely clear yet, if you come up, I'm afraid you will be discovered by the other side, you just wait in the car, just pay attention to concealment, I think this case may be almost the same tonight." ”

Da Leizi told us both to be careful, and quickly hung up the phone.

I looked at Leng Tong, and Leng Tong nodded.

I looked at Zhuang Sheng and asked: "Zhuang Sheng, there are some things you can't hide, I can tell you the truth, in those two bottles of drinks just now, there are sleeping pills, if we didn't find out the secret, you would have turned into a corpse in a while, lying in the bathtub, don't you want to say it?" ”

Zhuang Sheng still shook his head: "I don't know anything, I really don't know anything, I don't understand what you say, and no one will kill me, I won't live here tomorrow, go to my father's house to live." ”

"Zhuang Sheng, what you think is too simple." I said coldly: "Since the murderer has set his sights on you, it's not that you can solve the problem by changing places, your only way is to tell us the truth." ”

"I don't really have anything to say." Zhuang Sheng looked a little upset, and said with a little weakness: "This suicide case has nothing to do with me. ”

"That's not right, right?" I stared at Zhuang Sheng and said, "It doesn't matter, why did the murderer kill you?" ”

Zhuang Sheng was stunned again, and quickly shook his head and said, "Then how do I know?" ”

Leng Tong also looked a little angry, and couldn't help but ask: "Just now when we said that Cheng Zhuo and Li Yan joined forces to kill you, why did you say that it was impossible?" ”

Zhuang Sheng looked at us and said: "Li Yan is the owner of the store, he has been here for a long time, he is not bad, Cheng Zhuo is a unit, of course he can't kill me, as for what sleeping pills you are talking about, how do I know?" ”

I feel a little angry in my heart, I feel that this Zhuang Sheng must know something, even if he lives or dies, we can't help it, now Zhuang Sheng may be the next victim, but he is by no means the murderer!

At this time, there was a sound of footsteps in the corridor, Leng Tong and I were excited, it was about half an hour now, and if the murderer appeared, it would be about the same time.

But the voice in the corridor was not a murderer, but a group of children, who were fighting and making trouble, and they were not going upstairs, but they were fighting in the corridor.

This situation makes us both very anxious, these children make a fuss, if the murderer wants to unlock the lock, he will not come, isn't this a delay?

Helplessly, the two of us can't go out, and Zhuang Sheng can't go out, if you want to catch the murderer, you can only wait for the murderer to unlock and come in.

Seeing that the sky outside was gradually getting darker, there was still no movement.

Leng Tong looked at me and said, "It doesn't look like it will appear today, and the family will be back soon." ”

I looked at the photo of Zhuang Sheng and his wife's wedding dress on the wall, nodded and said, "Yes! It's impossible today, so let's go, shall we? ”

"Okay, let's go!" Leng Tong stood up and stared at Zhuang Sheng and said: "We came to talk to you today, I hope you don't say it, we are here to save you, you may be the murderer's next target, if you want to tell us the truth when you want, you can call us at any time." ”

"Good, good!" Zhuang Sheng saw that we were leaving, so he nodded again and again, stood up and said, "Then I'll send you." ”

The two of us glanced at each other, and left Zhuang Sheng's house a little helplessly.

The children in the corridor have long been gone, and it is getting dark, we know that Li Yan is staring at this side and can't see anything clearly, so she went out of the corridor directly and went around from behind to find the car.

Da Leizi was already waiting in the car, and when he saw us coming back, he hurriedly asked, "How is the situation?" Has the murderer gone? ”

"There was some accident, I didn't go!" I shook my head a little helplessly, looked at Leng Tong and said, "Tongtong, this Zhuang Sheng must know something, but he won't say, what's the situation?" ”

"There must be a reason why he didn't say it, maybe this matter can't be said?" Leng Tong also looked at me and said, "We still have a lot of things that we haven't figured out, but Li Yan can already be sure." ”

Da Leizi said with some disdain at this time: "Are you two thinking too much? Li Yan sold people drinks with sleeping pills, just to kill people, we arrested Li Yan directly, don't you know everything after interrogation? ”

"Li Yan is just an accomplice, not a murderer, the murderer is someone else." Leng Tong shook his head slightly and said: "If there is no way in the end, we can directly arrest Li Yan and ask the murderer, but now we have the opportunity to catch the murderer together, so we can't be in a hurry." ”

"You'll be in a hurry to kill one more." Da Leizi pouted and said: "Then we will all have a dull face, and even this case will be big!" ”

I thought for a while before saying: "Tongtong is right, now Li Yan is just an accomplice, if she doesn't admit it, she is indeed not a murderer, then the case is not easy to handle, I feel that this case must not be simple, if the murderer is not caught, Li Yanzhen may not admit it." ”

Leng Tong suddenly asked: "Xiaoxiao, Li Yan has already sold the drink to Zhuang Sheng, and Zhuang Sheng also looks nervous, but why didn't the murderer appear?" ”

"Maybe those kids are making trouble, right? Other than that······" I thought about it and exclaimed, "That Aunt Chen who swept the stairs? Quite possibly! ”

Leng Tong stared at the big eyes and said, "Tell me your reasons." ”

"There was a problem when we speculated before, and that was the problem of the victim not drinking it when he bought it." I really thought it might be Aunt Chen, so I continued: "But you also saw the situation this afternoon, Aunt Chen went to knock on the door!" ”

"If the victim drinks, then when she knocks on the door, there must be no one inside answering the door, and she can technically open the lock and come in and kill people." Leng Tong continued: "If the victim didn't drink, then she could say that she wanted some water to clean the corridor, otherwise the corridor would be dusty, and in this way, there would be no flaws!" ”

"Yes!" I nodded again and again this time and said: "It is very possible for this Aunt Chen who sweeps the corridor, she will come to ask for water today, if the dosage of sleeping pills in the drink is mastered, even if she doesn't kill people, she will just sleep groggily for a few more hours, and there should be no problem." ”

Leng Tong also nodded and analyzed: "If that's the case, we are looking for that person with a short figure, and he is not a murderer at all!" ”

I thought about it for a while before saying: "In terms of reasonableness, the possibility of Aunt Chen's murder is very high, and the other person with a short figure is a little unclear, Brother Lei found the flaw in our analysis, I feel that this Aunt Chen is more likely." ”

"By the way, I also remembered one thing." Leng Tong also said at this time: "I remember you also asked, why these cases are all used in this way, it will definitely arouse suspicion, I said at that time that the murderer may be to blame the supernatural event, or it may be the last resort." ”

Now I figured it out: "It should be like this, that Aunt Chen who swept the corridor is thin and small, and she has no way to kill a person easily except for using sleeping pills." ”

"It's very likely!" Leng Tong was happy: "If that's the case, we have one more subject to investigate, we can investigate this Aunt Chen, the relationship between her and Li Yan must be very unusual, and the process of killing people was completed by the two of them!" ”

"Probably not wrong." I smiled and asked, "But what about Cheng Zhuo and Zhuang Sheng, I feel that they both have problems, what is going on with these people?" ”

Leng Tong shook his head: "This case may be very complicated, there are many things in it that we don't understand, but our analysis is correct, and the target of tomorrow's investigation has also come out, that is, Aunt Chen, where did this person come from, and does it have anything to do with Li Yan." ”

I thought about it and said, "I think we should also investigate the case of Li Yan and her husband Yu Hongpei, the police must have a file, maybe there are any clues." ”

Leng Tong thought about it and said: "Okay, tomorrow we will divide into three ways, I will go to investigate the file of Yu Hongpei's car accident case, Xiaoxiao is staring at Li Yan here, Da Leizi, you go to the sanitation department, investigate this Aunt Chen, and call at any time." ”

I knew that Leng Tong had given me the easiest task, and Li Yan had nothing to stare at in the morning.

Da Leizi didn't care about that, he just did something happily, and quickly nodded and said, "That's not a problem, let's eat first, right?" From morning to afternoon, and afternoon until midnight! ”

Leng Tong and I almost didn't laugh out loud, we didn't eat at noon, and we said that we would eat at three o'clock in the afternoon, but there was a problem halfway, and we hadn't eaten until this time.
