Chen Shi called Peng Sijue and wanted him to send a few technical police officers to identify the traces, but the phone could not get through. Lin Dongxue said, "Captain Peng is still dissecting Xiao Wei's body now, right? Why don't you come back tomorrow!"
"Someone climbed out of this window that night. The point is not the trace on the window frame, but the suspicious piece of fiber on the pipe. Can we remove that ourselves?"
"This is not so good. I just saw it. The piece of fiber is on the fifth floor. It's too dangerous to lean out of the bathroom window to pick it up."
"Then let's go to the fifth floor!"
Lin Dongxue smiled bitterly, "All right!"
The two knocked on the door of the tenant on the fifth floor and took the small piece of fiber stuck in the pipe from the window and put it in the evidence bag. Chen Shi said excitedly: "Just find out who left it. I know who killed Duan Lin!"
"Why didn't the corpse man leave it behind?"
"Uncle said that when he came back on the morning of the 24th, the door of the house was open. I checked it before that the lock was opened with a key. The person with the spare key is most likely Duan Lin's boyfriend. After Duan Lin committed suicide, her boyfriend ran to the aftermath and took the cell phone. At this time, the corpse man arrived, and the boyfriend ran away from the bathroom window in a panic. Then the corpse man split Duan Lin's body in the bathroom and cleaned the scene before dawn , And take the corpse away."
"So did the corpse man see his boyfriend?"
"Obviously I didn't see it."
"Then how did he know that his boyfriend was among the nine? How did he know Duan Lin committed suicide?"
"Yes, how did he know?" Chen Shi's eyes lit up, "I understand, he is also among the nine!"
Lin Dongxue's eyes widened in surprise, "This seems to make sense... But the premise that this reasoning can be established is that the uncle did not lie this time."
"Just check the surveillance in the waiting room to know if he lied..."
"Shall we go to the bus station now?"
Chen Shi checked his watch, it was late, "No, go see Zhang Xiao!"
Calling Zhang Xiao, Zhang Xiao said that he was off work and was waiting for a bus on a certain street. Chen Shi told him not to walk around, and they would arrive immediately.
Half an hour later, the two met Zhang Xiao. He was dressed more decently after get off work, and he smelled of shoe polish. As soon as he saw Lin Dongxue, he greeted him with a smile on his face. Chen Shi said, "Let's find a place to talk."
"There is a Starbucks nearby."
When he came to Starbucks, Zhang Xiao expertly ordered a bunch of food and drink, just like a regular customer. Chen Shi wanted this kid to take himself as a victim. Zhang Xiao finished the order and asked: "Aren't you two order?"
"No, you pay for your own food."
"Oh, why did the police dig so hard."
"It's not easy to make money... Let's talk about business, what are you doing on the night of the 23rd?"
"Dinner with friends."
"Nine of you together?"
"No, just me, XX, XX, XX, XX, and XX, six of us."
"Why are you six?"
"Because a few of us were playing together, I forgot to say that XX and XX and I are in the first phase, the other three are in the second phase, and Xiaosi, Xiaowei, and Daniel are in the third phase."
"Why make such a distinction?"
"Because our nature is equivalent to a training class, the primary four hadn't graduated at the time, and they were taking online classes."
"Who is going to take the online class? Do you have a teacher?"
"It's usually video lectures. Sometimes I will be a guest lecturer and personally guide new students." Zhang Xiao showed a proud expression.
Lin Dongxue took out a small notebook and wrote down this clue. Zhang Xiao mentioned the names of several teachers.
At this time, the waiter brought the food Zhang Xiao had ordered. Zhang Xiao was deliberately attentive and said: "Let's eat together, you guys ask me for a question, isn't it normal to have a cup of coffee?"
Chen Shi glanced at the piles of coffee, tiramisu, sandwiches, and pudding on the table, and smiled: "If you order a cup, I can buy you, but I can't afford so much."
"Then did you settle the money for this cup of coffee?" Zhang Xiao said with a grin.
Chen Shixin thought, this kid is really shrewd, and said: "As long as you answer the questions honestly, a cup of coffee is fine."
"Just ask."
"Where did you go after the dinner?"
"Go home!"
"Where is the dinner?"
"Caiyuanzi Restaurant."
"until when?"
"It's over ten o'clock."
"You took the taxi back alone?"
"Yes."
Chen Shi stretched out his hand, "Let me see your taxi record that day!"
Zhang Xiao stopped eating, raised his head from the cake, a trace of panic passed across his crumbs-stained face, he said, "Delete!"
"It doesn't matter, you show me your phone."
"Really deleted."
"Actually, I'm not a policeman, I'm a criminal investigation consultant. My job is to drive online car-hailing. I know this system well. Show me your app. It doesn't matter if you delete it. I can find your record. "
Zhang Xiao didn't speak, his brows furrowed, he himself didn't notice that his right hand was squeezing the cake into powder.
This detail was exposed in the eyes of Chen Shi and Lin Dongxue, and Lin Dongxue thought to herself that the case was solved now.
"You are Duan Lin's boyfriend, the one who made her commit suicide, right?" Chen Shi asked every word.
"No, no, no!" Zhang Xiao desperately denied, "I don't know her, I have a girlfriend now, if I don't believe it, I will call her now."
"This proves nothing. It's normal for a person like you to have several girlfriends at the same time."
"What do you mean... What do you mean!" Zhang Xiao started filming the case, "I just look down on PUA and just say, my looks, this family, there is a serious woman willing to throw me, two years ago I even a woman's hand I've been involved, if it weren't for PUA, I'm still single! To put it bluntly, you are jealous that I have a relationship of the opposite sex. The crows in the world are generally black. They are all big masters. They are all animals that think in the lower body. Have you ever eaten with Police Officer Lin behind your back for the guarantee?"
Suddenly Zhang Xiao started to make trouble unreasonably, and the words spoken incoherently, caused many customers in the coffee shop to look here, and Chen Shi looked on coldly. The source of his anger was his guilty conscience.
"Can we talk like adults..."
Suddenly Zhang Xiao fell to the ground, convulsed all over, and foamed at the mouth. At first, Chen Shi thought he was acting, but looked different, and said, "Call an ambulance!"
Half an hour later, Zhang Xiao was sent to the hospital, and Lin Dongxue said, "This disease happened too coincidentally, right?"
"It's a coincidence, but we already know that Zhang Xiao is Duan Lin's boyfriend."
"Then is he in danger?"
"Danger?" Chen Shi thought of something, "Yes, the murderer was in the group. When he lied before, the murderer had seen him through! Maybe the murderer will come to him tonight!"
