Jiang Dong called Xiao Han next to him over, whispered something, and Xiao Han went out, and came in with a laptop after a while. He opened a video for Li Yifan to see. The video is from a surveillance camera near the exit of the park, and in the bottom corner of the picture there is a couple arguing in the park, and after a while, seven or eight boys pass by.

Li Yifan recognized the group of people at once, ten days ago, Li Yifan and a few classmates in their class went to the gallery to see the latest art exhibition, just passing by a park, when they saw a couple arguing, but they only looked at it a few times, when the girl was crying, while pointing hoarsely at the boy in front of him and scolding. It's normal for couples to quarrel with each other, so Li Yifan and they looked at it a few times before turning their heads and leaving. It's just that the girl in the photo looks gentle and elegant, and she doesn't match the girl with tears on her face at the time, so he didn't recognize it at all.

"She was arguing with a boy when we passed by, and I only saw a girl crying and scolding a boy, and I didn't pay much attention to it......" Li Yifan thought in his mind, it seems that Bai Ran's report is right, he subconsciously has delusions about what is about to happen to someone?

"I'm going to let you help me confirm what you saw and ignored in our on-site investigation." Jiang Dong thought for a while, and then continued: "Why do you always think that they were killed? Although the first drowning case was closed a week ago, and the family of the deceased had taken away the body, there were still doubts in Jiang Dong's heart, although the report had been handed in, he still felt a little strange, especially when he saw Li Yifan's cartoons, he almost suspected that Li Yifan was at the scene of the crime. Now Jiang Dong is even more suspicious that Li Yifan and the man at the scene of the crime are in the same group, he doesn't believe that anyone can see the death process This kind of nonsense, he just wants Li Yifan to explain the whole process of the crime more clearly.

"The man...... Right! It's that man, did you see if there was that man in the surveillance at the time? There was a man in both cases, and I'm sure the second case was done by a man as well! Li Yifan said excitedly. I still remember the strength he had dragging me at that time, and the smell of his body, which is only for men. ”

"What does it smell like?" Jiang Dong asked him. Squinted at the excited boy in front of him, if it weren't for the strong alibi evidence he had. Jiang Dong may have arrested Li Yifan as soon as he saw the comics.

"I can't say, it's the kind of smell that only boys' coats have, and the smell is different from girls' clothes." These are what Wu Shuai told him, as long as this man is a straight man, even if he is a sissy again, the smell on his body is different from that of a woman, Wu Shuai said that the kind of smell on a man is like the wind.

"Well, anything else?" Jiang Dong looked at Li Yifan in front of him, and felt that what he said was nonsense. What kind of smell on the body, it sounds ridiculous, Jiang Dong is just waiting for Li Yifan to explain what happened.

"That'...... What about the surveillance, there should be surveillance in the park, didn't you see that man?! Li Yifan was a little excited at this meeting, and he felt Jiang Dong's attitude of doubting him. Yes, who would believe that someone could see others killed in a delusional way, hehe, even if he gave Li Yifan himself, he didn't want to believe it, he began to laugh at himself in his heart, he even expected the police to believe him! It's ridiculous.

"In the first case, the cameras by the river were broken a few days ago, only the entrance was clear, and there was a clear record of the deceased coming in, and the rest were some old aunts dancing in the square. No other suspicious people passed by the cameras at the various intersections, and no one else was found passing by the road where the deceased fell into the water. Jiang Dong looked at the report in his hand and gave a general description of the content.

"How could it be so coincidental that there were gardeners during the day that day...... Where to work? Li Yifan held his head that was still headache, how could the murderer leave evidence, looking at it this way, all this was planned a long time ago. That hideous smile appeared in Li Yifan's mind again, what a meticulous plan.

"......" Jiang Dong looked at the record in front of him, there were indeed many doubts at that time, and he had doubted it.

"That'...... Xiao Liu's ...... What about apartments? There must also be surveillance in the apartment building, so it's impossible not to find a suspect! Li Yifan looked at Jiang Dong, there must be some evidence, it is impossible that there is no evidence at all!

"There were no suspicious people at that time, neither the elevator nor the corridor." What Li Yifan said, Jiang Dong and his police have already investigated. He was already a little impatient and unwilling to answer Li Yifan's question on the other side. He was brought here to interrogate him, and he was always asking questions.

"That...... Xiao Liu...... On Liu Xiaofei's body, are there any traces of being dragged...... Under the arms, there are also heels. Li Yifan gestured as he spoke, recalling the whole process of being dragged in the room.

Jiang Dong looked at the young man in front of him who was doing strange movements, and frowned, not knowing what he wanted to express. He looked through the notebook in front of him again, and the notebook recorded that there were no other traces on Liu Xiaofei's body. At that time, after confirming that it was not him who killed him, he closed the case by suicide, but Jiang Dong felt that it was still a little suspicious, so he pressed the closing file and never handed it in.

"......" Li Yifan looked at Jiang Dong in front of him, and shook his head in disappointment, yes, why did he think that others would believe in him.

After speaking, Jiang Dong got up and prepared to leave, and Li Yifan also walked out of the interrogation room with him. When he first arrived at the door, Jiang Dong said, "Do you know a teacher surnamed Tan?" He was at the scene of the crime yesterday and should be under investigation now. Li Yifan was stunned for a moment when he heard this, and then walked out with Jiang Dong.

Jiang Dong said something to the person next to him, and the other party took Li Yifan to a single room in the detention center. The other party detained Li Yifan for 24 hours on the grounds that Li Yifan was related to these two cases. Li Yifan sat on the bed, curled up slightly, and let the whole body that was trembling a little because of helplessness lean against the corner, looking at the white swaying sun outside the window, Li Yifan felt a little confused and aggrieved.

Just after separating from Li Yifan, Jiang Dong went back to the office, and the conversation with Li Yifan just now was still very rewarding. He found an important piece of information, in both cases, a man appeared, and both cases were vigorously disguised as suicides, could it be a serial murder case? Of course, on the premise that Li Yifan's delusions are true, he has always emphasized that there is a suspicious man in both cases. These two girls can't be allowed to die in vain at the age when they should be in the mood for love. There are still so many doubts in the case, and he must solve them step by step.

"Huh." Jiang Dongdu began to laugh at himself, there was really no other evidence, and he would believe that kind of words. Jiang Dong looked at the surveillance records on the table about the two cases, and there was nothing suspicious. "In the second case, the deceased had lost contact three days ago......" Jiang Dong looked at Xiao Han who was standing beside him. You said...... Could the killer have been lurking in the deceased's house three days ago? Jiang Dong was suddenly excited, and slapped Xiao Han on the shoulder, this slap was quite powerful, and Xiao Han's whole person was a little untenable. yes, I didn't think of that! ”

Because Jiang Dong had a little more strength when he patted Xiao Han, the stack of materials in Xiao Han's hand suddenly slipped down and fell to the ground. Jiang Dong laughed and scolded that Xiao Han was powerless, and helped him pick up the information together. Jiang Dong seemed to have found a breakthrough point in the case, and it was difficult to hide his excitement. When Jiang Dong stood up and wanted to give the information to Xiao Han, he glanced at the information in his hand, which was about Li Yifan's medical records, and he saw the familiar name under the medical records, which Li Yifan had mentioned before.

"Toot ......" Jiang Dong picked up the phone, explained a few words to his subordinates, and then started the phone on the side. Hello Dr. Bai, I'm Jiang Dong......" Although the voice on the other end of the phone was already very familiar, Jiang Dong still reported himself first. "I want to ask you something about Li Yifan." After verifying the medical records on the data, Jiang Dong hung up the phone a little at a loss after inquiring about the situation, he was a little surprised by Bai Ran's attitude just now.

After a while, Jiang Dong's mobile phone rang, and Bai Ran sent three data maps to Jiang Dong, these could not be leaked, it is estimated that Bai Ran wanted to help Li Yifan, but he really couldn't think of any other way. In the end, Bai Ran sent a voice over, and after listening to that voice, Jiang Dong was a little stunned, Bai Ran, who had known him for so long, spoke to him in that pleading tone for the first time.
