Among these people, there are three people who have the most time to commit crimes, namely Zheng Lei, Ma Yingtai and Qiu Shuang. The murderer is definitely among them, and Zhao Yuanwu and his wife are really a little impossible, according to the testimony of the old couple, one was at Li Na's house at the time, and the other was working in the company.

The testimony also mentioned that in order to prove his innocence, Zhao Yuanwu deliberately took the police to the company to adjust the surveillance, proving that he had not left the company before Li Na's disappearance. Eating at noon is also a take-out, and the front and back doors of the company are monitored, and if he leaves by the time of going to the toilet, it is impossible to escape the monitoring range.

I don't believe Liu Yiyi's analysis of the remaining people, even if they are good, there will be another side that others can't see. What is hidden in the depths of the heart is human nature!

Then according to the modus operandi, the murderer's behavior is analyzed. The murderer must be a person with a good knowledge reserve and a little understanding of paranormal processing. I probably have a probability ranking of these people in mind.

At this point, the chaotic clues in my mind gradually cleared up, and I dropped my phone and went to sleep. I got up early the next day and went to visit them first.

First of all, Qiu Shuang, at this time, she had just returned from the radio not long ago. Just as I was about to sleep, I identified myself and showed my proof. She said she could give me a little time, and I asked her straight to the point: "Regarding Li Na's disappearance, you didn't prove that you weren't at the scene that day, do you have anything to say about this?" ”

Qiu Shuang made me a cup of tea, then sat down on the sofa opposite me and said, "I really don't have anyone to prove it for me, I would wake up at about four o'clock in the afternoon at a fixed time, and I usually go to see this child first." By this time, she had almost gone back. ”

"She's been a little annoyed lately, saying that she always feels like someone is following her and she's scared. She called me sister, and I also regarded this child as my own sister in my heart. At first, I thought that she was overthinking, and children at this age are the easiest to think more, but I didn't expect ......"

Speaking of this, the corners of her eyes were a little moist, and she actually lowered her head to wipe them. I took a sip of tea, it was quite fragrant, it was flower tea. "Anyone will be sad about this. Miss Qiu, have you been sleeping during this time? You said to wake up at four o'clock at a fixed time, so what made you not wake up that day? ”

"Because of work, the pressure was a bit high, and I couldn't sleep in the morning, so I drank some soothing medicine." Qiu Shuang said, got up and went to get the medicine to show me.

It is a diazepam tablet. This medicine does have a calming effect, and it works quickly.

"It was because of this that I slept until almost six o'clock. Something happened to her. Qiu Shuang's voice trembled slightly, and it could be seen that she was forcibly holding back the pain.

If she's acting, it's too realistic. Many movie stars may not be able to do it, so I put the medicine on the table, got up and said, "Miss Qiu, thank you for your cooperation." I know, but I recommend that you don't continue to take Valium tablets in the future, although this thing works quickly, but there is dependence. If you just have insomnia and calm your nerves, you can try to calm your nerves and replenish your brain. I'll go first. ”

"Mr. Chen." She suddenly stopped me.

I turned around and asked her if she was okay, Qiu Shuang handed me the phone and said, "Please be sure to leave a phone number for me, if the murderer is caught, I want to see him sentenced no matter what." ”

"This is my number, you call me one, let's keep each other." I typed my phone number into her phone and said.

Qiu Shuang took it and called me one, I saved it and said a word of interruption, turned around and left.

Next is Ma Yingtai, who has a habit of running in the morning, and should already be in the park by this time. According to the address written in the testimony, I also quickly found the park, and found Ma Yingtai, who had stopped to rest.

When I told him what had happened, he pointed to the gazebo in front of me and said, "That's where I played chess with some old men that day, and because I lost a few games, I was not reconciled, and I didn't go home until about half past six." ”

"What do you think of Li Na?" I then asked.

"She? She is a well-behaved and sensible child, and she is also very polite, and every time she meets me, before I can open my mouth, she has already called her uncle loudly. When Ma Yingtai mentioned Li Na, there was more regret and helplessness in her eyes. Who knew that such a young child would encounter such a thing. ”

"Based on the testimony you provided, there are also the signatures of those chess players on it, and I should no longer doubt it. However, in several of their personal testimonies, it is mentioned that around 4 p.m., you were away for more than half an hour, saying that you were going to eat. I asked.

Ma Yingtai nodded: "Yes, I was in this park at noon, because I was distracted from playing chess, and I forgot to eat." I didn't feel a little hungry until the afternoon. ”

"But the place you went to was not monitored, and Li Na happened at that time, so it doesn't prove that you are completely innocent. Can you provide us with a place to eat? I want to check it out. I replied.

"It's at the third intersection of Huaming Street, called a famous restaurant. It's a small noodle restaurant, so there's no surveillance. But I go there a lot, and his family knows me, so you can ask the boss. Ma Yingtai replied without hesitation and showed me the way.

I nodded, thanked me for my cooperation, and got up to leave.

Li Na last disappeared from surveillance at around 4:25 p.m., when she also passed by Wah Ming Street. This street is the only place for her to go home, and at the same time, according to Ma Yingtai, it is also the time when he is out of sight.

In this way, Ma Yingtai is indeed very suspicious, but I went to the noodle restaurant he said. found the boss Sun Youming, and confirmed that what Ma Yingtai said was true.

Finally, there is Zheng Lei, according to his testimony, he will go to the restaurant around 9 o'clock every day to wait for the delivery of takeaways. This time is about the same, but when I arrived at the restaurant, Zheng Lei had already gone to deliver takeaways.

In order not to lose time, I first chatted with the boss, who was a man in his thirties. Speaking in a set way, he looks like a shrewd person. First, he showed me the evidence of his alibi that day, and then called the clerk to corroborate it.

His surname is Li, and the name of the restaurant is very simple and rude - Boss Li's restaurant. Although it is called a restaurant, it is much larger and has a private room on the second floor. Boss Li also told me that because the business of the restaurant is very good, it is too late to register a takeaway company like others and wait for someone to take the order.

So he recruited a few employees on his own to specialize in food delivery. They all live in the store, and among them, Zheng Lei is a good seedling.

He said that this young man was a college student, and because he had not found his ideal job, he had come to work in the store temporarily. But he doesn't have the stinky temper of a college student at all, he is very diligent in doing things, and he is from the Polytechnic University, and he can fix many things in the store.

In order to save enough money early, he also registered with the takeaway company Pigeon Master part-time, and when the store was not busy, he went to other places to deliver takeaways.

Pigeon is a food delivery company that advocates the concept of part-time work for all. Sign a contract with those stores in the city that need to deliver takeaways, and then place an order on the mobile app, and after the registered takeaway pigeon takes the order, it will go to the store to pick up the things and send them to the buyer.

I noticed that there is a pizzeria next to Boss Li's restaurant, and as mentioned earlier, Li Na likes to eat pizza very much. In this way, there seems to be nothing wrong with it.

Boss Li also enthusiastically showed me the surveillance video of the store personnel, in which I found that at around 7 p.m. on August 10, Zheng Lei walked into the store with a wooden board in his hand, and then went to his room.
