Lin Dongxue whispered to Chen Shi: "Compared with Xiaodong's confession, Xiaodong said that Li Mengran was upstairs at ten o'clock."
Chen Shi nodded and asked Mother Wu, "Why didn't you tell the police."
"Isn't I still afraid of being suspected? I ran back to get my ID card last night. I didn't expect this to happen at all. I was worried that as soon as I said it, you would regard me as a suspect."
"Mr. Li was not there?"
"Mr. Li ran out to look for her, then came back secretly and took a sip of a drink... She drank the half bottle left in the refrigerator, and then took her ID card. She said she was going to run away and scare Mr. Li. When I go to an Internet cafe or hotel to spend the night, I especially told her to be careful, but it doesn't matter, wherever I go, it is monitored and safe... I don't know that this happened at one o'clock in the morning!"
"You didn't tell Mr. Li, it seems that you are usually towards her." Chen Shi said.
"Oh, you don’t know how strict Mr. Li’s tutoring is. However, in the entire high school, almost never sleeps for six hours a day. Not only does she have to go to evening study, but she also has a tutor to give her supplementary lessons. If the ranking drops a little, Mr. Li asked her to write by herself. The review book analyzes the reasons, often crying while writing... I looked at this child as pitiful. It was clear that his family was better than anyone else, and his life was ten times harder than an ordinary child, so I took special care of her at ordinary times. Right. , She ran back last night, and I even gave her a bag of biscuits that I baked."
"Her grades are quite good. Why should Mr. Li believe in a liar and buy her a college entrance examination paper?"
"Ah? How did you know about this! Mr. Li was also looking forward to her going to Peking University. In fact, I wanted to say that, despite the results, the prestigious schools below Peking University basically took the lead. However, Mr. Li just focused on Peking University, and it was because of yesterday. This quarrel, slapped her clearly, and ran her off."
"Anything else you want to tell us?"
Mother Wu shook her head.
Chen Shi took out the picture of the utility knife and said, "There is a clear blood test on this, as well as another person's fingerprint. You are the one who cleaned up the room. Most of the fingerprints belong to you... You know there is evidence. How unfavorable?"
Mother Wu was so scared that she covered her mouth and said, "I can explain this!"
"You said!"
"That was the time, Mr. Li forced Ranran to write a letter of guarantee, telling her not to contact the boy named Gao Xiang from now on. After writing the letter of guarantee, she cried all night. The next day, Mr. Li went on a business trip, but he didn't have any at 9 o'clock in the morning. When I got up, I yelled for a long time and didn’t see her promise. I was still wondering that this kid doesn’t usually sleep late! So I took the key to open the door, and when I saw it, I was lying on the bed with the knife in my hand and took my own My wrist was slit, and I was frightened. I immediately hit 120. Fortunately, there was no life-threatening situation. If Mr. Li knew how serious the incident was, I would keep it secret."
"Do you know the reason? Is it because Mr. Li beat the mandarin duck?"
"No, no, I told me later. In fact, she just had a good feeling for Gao Xiang, but she didn't fall in love. Gao Xiang sent her home that night, and actually did something to her in an alley, if it wasn't a kind crossing. People stopped her and she was almost ruined. But the more she came back, the more she thought about it, the more frightened she was. She didn't dare to go to work again, and she didn't dare to tell her family, she did a stupid thing!"
"You put away the knife?"
"I put it away, and I'm afraid I will do stupid things again, hiding behind the test papers she has already done."
Chen Shi is going to leave the beverage bottle that Li Mengran drank last night, and the cookies that Wu's mother baked. Wu's mother actually bake cookies. She said that because Ranran loves this, the baked cookies are tied up with a small plastic bag. There are five bags in total.
Chen Shi said: "We are not suspicious of you, but we have to ask you to go to the bureau, repeat these words just now, and make a detailed confession. Because now another person is suspected, your confession can clear his suspicion. "
"Don't doubt him, do you doubt me?" Wu Ma asked worriedly.
"How could it happen? You have no motives and no time. I know you are very good to Ranran. Your testimony shortened the time for Ranran to be killed. It is very helpful to our investigation."
"Okay, okay, you have to explain to Mr. Li."
"must!"
Lin Dongxue called the bureau and the case has now been filed, but the third team is in charge. After Lin Qiupu's discussion, the third team agreed that Chen Shi and Lin Dongxue would participate in the investigation.
Lin Dongxue contacted the team leader of the third team and asked him to come and take Ma Wu back to make a statement.
The two left for a while and went out. Chen Shi pressed the upward elevator. Lin Dongxue said, "You pressed the wrong one!"
"I'll go upstairs and take a look."
"Go upstairs?"
"If what Wu Ma said is true, I think Li Mengran still likes Gao Xiang, so when Gao Xiang acts indecently towards her, she will have a strong sense of disillusionment and take extreme suicidal behavior."
"Do you think Gao Xiang is suspicious?"
“I’m not sure if I haven’t seen anyone, but I don’t plan to go to school. First, the crime is so sophisticated and it’s unlikely that the murderer is a student. Second, the school’s interpersonal relationship is very complicated. Can't find it, let the third team go to the muddy water!"
"Are you just waiting to steal the fruits of victory?"
"How can it be called stealing the fruits of victory? There are fast or slow investigations. If there is enough manpower, I will investigate slowly. Now it is the two of us. I can only check quickly! I will make a list in my heart to see who has the probability of committing the crime. If it’s too big, it’s the priority to check who is. This method is a bit of a gamble, but it is also a stopgap measure."
"But you can always bet right!"
"Luck!" Chen Shi smiled. In fact, what he really wanted to talk about was inspiration, and put himself in a position to simulate the murderer's thoughts.
The two took the elevator to the top floor and went up to the roof. The roof door was locked. Chen Shi said to Lin Dongxue, "Go find the property."
"Oh!"
As soon as Lin Dongxue walked down, Chen Shi took out the unlocking tool from his pocket, opened the lock quickly, and said, "Come back! Come back! I don't know which Ma Daha didn't fasten the lock, I just pulled it open."
Lin Dongxue came up and looked at him incredulously, "You are lucky too!"
When I came to the rooftop, although it was already evening, it was dark in summer and the surroundings were still visible.
Chen Shi looked around and kept taking pictures with his mobile phone. Lin Dongxue asked, "What are you taking?"
"Look at where this neighborhood matches the location of the assault. There is dirt on the corpse. Come and see." Chen Shi showed her the photo, and the two discussed.
"Although there is soil in the flower beds on the roadside, it is impossible for cars to come and go! PASS!"
"There is a playground in this school, and it is very quiet at night, but will Li Mengran go there? PASS!"
After PASS dropped a bunch of photos, there was finally a place nearby, a construction site, and the two decided to go there now.
