When Li Jing and Team Xiao arrived, I had already been sitting at the nearby police station for an hour, and I sent a message in advance to tell Li Jing what had happened, so they didn't panic when they rushed over, and Team Xiao and the police next to them talked about Liu Sheng. Li Jing scolded me crackling when he saw me, and finally looked at me with a frown: "It's really a good job, dare to take the lead by yourself." ”

I knew that he was concerned about me, so I automatically ignored the sarcasm in his tone and smiled at him stupidly: "Am I fine?" Don't be angry. However, your method of going to Islam really works, I have been testing Liu Sheng's bottom line just now. When he collapsed, he really confided in Zhang Chengyu. ”

After shaking off my eyes, Li Jing finally began to tell me about Liu Sheng: "I really didn't teach you in vain, I know that he has cleanliness and obsessive-compulsive disorder, I can think of such a way to put psychological pressure on him, and I also know that I secretly recorded him, but this kid has a hard mouth, and he is sure that he is just afraid that he will get into trouble at that time." ”

I was puzzled: "Supposedly, since they have a photo with Zhang Chengyu, why do they want to take the same photo with me, isn't this an extra move?" ”

Li Jing sneered: "It's not an extra move, the photos they gave to the police at that time were perfectly photoshopped." ”

"Huh?" What the hell is going on, I'm getting more and more confused.

"Li Chengyu's body was found by the police a long time ago, and it is not missing at all. The modus operandi was similar to that of an unsolved serial killer case in a foreign country at the time. Your school was afraid that the panic would spread, so they forcibly suppressed the matter. At that time, I investigated all the people Li Chengyu knew, saying that it was an investigation, because the methods were too similar at that time, it was just to collect clues and see if there were any strange people entering and leaving the school. At that time, someone said that when they saw him finally go to your club, and when the police went to investigate, they showed the photos you saw on the forum. ”

"Didn't Brother Shi Hao say that there was nothing wrong with that photo?" Didn't Brother Shi Hao deny PS on the phone yesterday?

"That's where they are smart, they didn't directly deduct you and replace you with Li Chengyu, they should have had an identical photo before. They cut out a few people in the original film, replaced them with the photos you took, and then adjusted the brightness and saturation, and used software to eliminate the PS traces, so just looking at Zhang Chengyu in the photo, you can't find any traces of modification. ”

"And how did you find out about his tricks?" I still think the whole thing is amazing.

Li Jing suddenly became very reluctant, and without answering, I went over to learn about Liu Sheng's situation with Team Xiao, inexplicably.

Because of my recording and nonsense in the restaurant, it helped Liu Sheng's investigation a lot, and the Xiao team seized the time to start interrogating Liu Sheng that night. And Li Jing is responsible for doing the profile on the side.

The time he had been arguing with me in the restaurant just now, coupled with the fact that he had explained to the police station for a long time, and the oil stain on his body, Liu Sheng now looked exhausted. Liu Sheng kept changing his sitting posture, adjusting his discomfort caused by cleanliness. Team Xiao walked into the interrogation room with disinfectant tissues and clean coats, and motioned for Liu Sheng to change into clean coats and wipe down his seat to relieve his current discomfort. After a busy day, Liu Sheng's feelings had calmed down a lot, and his expression when he looked at Team Xiao relaxed. Seeing that Liu Sheng was no longer as repulsive to him as he was just now, Team Xiao began a routine questioning, while we zoomed in on the screen and observed the subtle changes in Liu Sheng's expression.

"You say you young man loves cleanliness so much." Team Xiao teased.

Liu Sheng didn't give a reaction, and looked at Team Xiao without saying a word.

"Tell me what the last words in the restaurant mean." Seeing that he didn't react, Team Xiao went straight to the point.

Liu Sheng didn't speak, I remember that when I participated in activities in the club before, Liu Sheng once talked about how to avoid the police investigation and break free time for himself, the easiest way is to remain silent, the more he talked, the more loopholes.

Thinking of this, I touched Li Jing: "Li Jing, what our university community studies is the criminal psychology research and reasoning of serial killers. Senior Liu Sheng should know how to avoid questions. ”

"Watching for a while." Li Jing is not impatient.

"Hey, you're not the same kid as the girl just now. When I asked the girl, she was so frightened that she dared to say anything. "The girl Xiao said is probably me.

Liu Sheng's expression did not change significantly, but Li Jing pursed his lips as he looked at the monitor.

"The girl said that you would not give you a photo, and she was angry with her, which frightened her. What kind of photos? Let you lose your temper with a girl? It can't be a picture of your ex-girlfriend, right? ”

Yanagi was still expressionless, but when he talked about the photo, he could still see the slight beating of his eyelids, but when he heard the words behind Team Xiao, he regained his calmness.

"I see that you should have a good tutor, how can you have such a big temper, okay, change your temper in the future, how bad the impact is. I'll ask the restaurant owner in a moment, and if he thinks it's okay, you two can go. Talk well in the future, don't quarrel! But if people don't give up, they can only ask your family to lead people. Team Xiao got up and went out.

Team Xiao walked into the monitoring room and asked Li Jing, "Did you find anything?" ”

Li Jing played back the video, stopped at Team Xiao's third question, pointed to Liu Sheng on the VCR and said, "Team Xiao, look, when he heard Xiaozhi tell everything, his pupils were obviously dilated. ”

Team Xiao and I approached the screen to take a closer look, and really, my pupils were more than doubled.

Also, when I heard the photo, there was a noticeable change in my expression. Photos are the starting point. And your last question, when talking about his family, his expression changed even more obviously. I'm asking Shi Hao to help check Liu Sheng's family background. By the way, there is also the progress of Zhang Chengyu's case. ”

"Did Shi Hao find the original photo of the collage?" Team Xiao asked.

"No, but the photos they had given to the police were found. Although the photo was not evidence at that time, and the police did not take it away, an activity on the Internet of Xiaozhi and their school at that time forced the administrator at the time to get the photo and publish it. The photo analyzed by Shi Hao was asked by the administrator on the search site. ”

"Okay, help me print out the photos, I'll continue to interrogate that kid, there is progress in the background information, let Xiao Wang call me." That kid has a hard mouth. The team got up and went back to the interrogation room.

When he returned to the interrogation room, Team Xiao had a photo in his notebook, but he didn't take it out, but continued to chat with Liu Sheng. Team Xiao handed Liu Sheng a glass of water, and I quietly applied a little nail polish on the disposable paper cup, but the nail polish did not dry, and when Liu Sheng went, his fingers were stained with some nail polish, and Liu Sheng's expression became panicked. Li Jing said with a smile: "Your trick is really bad!" ”

"You asked me to get his love out a little earlier now, so it's easy to catch the loophole." I replied.

The two of us continued to observe the situation in the interrogation room

"I told the boss just now, but the boss disagreed, saying that it was a trivial matter for you to make trouble at his house, but it was a big deal that you killed someone." Team Xiao exaggerated the restaurant owner's rhetoric a little.

"I didn't kill anyone." Liu Sheng finally gave a reaction, maybe he was afraid that if he was silent now, he would be questioned by Team Xiao as a default.

"But you said that in order to prove that Zhang Chengyu is not dead, how do you explain it?" Team Xiao showed me a recording.

After listening to the recording, Liu Sheng stopped talking again, but saw that his eyes began to be against the table.

"And this picture? How do you explain this photoshopped photo? Team Xiao took out the photo from the notebook and showed it to Liu Sheng, Liu Sheng's face changed suddenly, his mouth opened and closed several times, and he was speechless in shock.

Finally, he calmed down his feelings before he spoke: "I don't know what this photo is about. ”

"But the girl said he was a photographer for you." Team Xiao stared at Liu Sheng deadly.

Liu Sheng's eyes widened: "Impossible! She wasn't there when we took the picture. ”

Team Xiao smiled, and Liu Sheng looked at Team Xiao's smile and knew that he had been tricked.
