Li Jing ignored their frozen expressions, and just said flatly: "I've always wondered why Liu Yi would find a child who never participates in activities to help you investigate the death of your lover. It is said that it would be more reliable to find a private detective for this kind of thing, but you have found Xiaozhi who has no experience to help, you know that she will not refuse you, she will look for others for help if her own ability is not enough, and the other forces around her are what you need most, right? ”

Senior Sister Liu Yi still bit her lip and didn't speak.

"I didn't break it at the time, because I knew that what you wanted us to look into was not as simple as you said. Sure enough, after finding out, Zhang Chengyu's case was introduced. As Zhang Xue mentioned that time, this is a mistake you made when you were young and can never make up for it. ”

Li Jing stopped at this point, he glanced at the two people opposite, then looked at me, and motioned for me to tell the relationship that I had only sorted out in the morning.

"Zhang Xue, I called Zhang Chengyu's former classmates this morning, and I have always wondered why you care too much about Li Chengyu in everyone's mouth. It wasn't until today that I read your material that I understood your madness at the time. "I glanced at Zhang Xue, and when I heard me say 'information', she straightened her waist because of shock, and I continued: "You and Li Chengyu are brother and sister, right? I don't know if he knows about it, but I'm sure you do, right? To Xiaolan? ”

Zhang Xue's eyes were obviously bigger than just now, she shouldn't have expected that I even knew her former name so clearly, she smiled bitterly and asked me, "Do you know anything else?" ”

I shook my head, "There are only so many, but I wonder why you hurt your own brother?" ”

Zhang Xue pursed her mouth, her eyes were a little red: "Yes, why should I hurt him!" ”

Liu Yi saw Zhang Xue crying, but she was calmer than just now, and took my question: "Things are not what you think." After a pause, Senior Sister Liu Yi seemed to have made a lot of determination before she began to say, "Things are much more complicated than you think. ”

"Who is he?" I asked them, and no one answered.

Li Jing flipped through the notepad he was carrying: "They are talking about Li Chengyu." In the two years that Li Chengyu entered the school, there were a total of 4 laborers in your university town, and the murderer has never been caught, but because your club is studying the mode of serial killers, it is impossible for you not to study this matter as a research object, and you have figured out your own efforts to find the murderer. In order to suppress such a matter, the school did not fully cooperate with the police investigation, resulting in the police always mistaking the behavior of off-campus workers. But you, as the only club in the school that deals with reasoning, will also arouse your suspicions in the small talk of the usual academic staff, so you start to investigate on your own. All your reasoning is pushed to one person, and that is Lee Sung-woo in that composite photo. Lee Sung-woo is the boyfriend of Yoo Yi, a member of your club, and usually attends your events, and has developed a keen interest in the murderous details of some of these serial killers. ”

Li Jing put down his notebook and looked at Zhang Xue in front of him: "This connection of blood is very strange, even if you haven't seen you for so many years, you still recognize your brother." In order to get to know your brother better or become closer to your brother, you often follow your brother and find out that your brother is emotionally abnormal. I guess you saw your brother in the school abusing animals and other early signs of violence, and you combined with some of his previous things, and you became suspicious of him. When your suspicions are verified, you want to stop him, but it's too late. I guess I don't need to say more about the rest of the story, right? It doesn't matter if you don't admit it, before your brother went to college, there was also a homicide in their hometown, and the victim was an outsider who came to their village to work. The modus operandi is also consistent with the murders that took place in college towns. ”

Zhang Xue had already shaken off the shock just now at this time, and said lightly: "But I didn't kill him." ”

"I didn't say you killed him. Someone else killed him. Li Jing looked at Senior Sister Liu Yi again, "Thank you for designing a play for Xiao Zhi to jump in and help you investigate without hesitation." You don't want to admit it, so I'll go on. You are all members of a club, so not only you, but others have also discovered the strange behavior and abnormal behavior of Liu Yi's boyfriend. When you realize that something is wrong, everyone starts to suspect your brother, you defend your brother, no one believes you, and then you find out that your brother has disappeared, so you use a clue to find your brother, so there is news that you frequently went in and out of his classmates to inquire about him during that time. Your members of the community went to your brother without telling you, probably during their conversation with your brother, and your brother was mentally confused, became cognitively impaired, and took your friends as his target and tried to kill them, only to be mistakenly killed by your companions during the dispute. ”

Speaking of this, Li Jing paused, observing the other party's reaction, Senior Sister Liu Yi lowered her head again, he snorted disdainfully and continued, "Although you are helping the police solve the case, but it is also manslaughter, you know that manslaughter will also be sentenced, and you also know that this time it involves students in the school, the teacher will definitely cooperate with the police to do a thorough investigation for the safety of the students in the school, in order to escape responsibility, you have thought of a way to blame others." You chose the modus operandi of the famous 'Green Forest Monster' at the time, and disguised the corpse. Because the 'Green Forest Monster' did commit crimes in some Asian countries at that time, and the closest crime to you was in a nearby city, you simply started to act as a copycat, hoping to confuse the police. You have done a very meticulous job, and the investigation is also very clear, and you have learned about the kinship between Li Chengyu and Zhang Xue, you know that Zhang Xue has no way to tell the truth about his murders, and you don't want you to disclose the news to the police, so you want to coerce Zhang Xue to cooperate with you to create an alibi. Some of you should have access to the school's cold storage, where you hide the corpse to slow down the decay and buy time for you to make an alibi for yourself. In the afternoon of the same day, you tricked Xiaozhi into going out to take photos with you, and in the post-compositing process, you did the final processing of the corpse. It was found a few days later, because the body was professionally handled, which affected the time of forensic judgment. If I was right, Miss Liu Yi, who specialized in anatomy at the time, was the one who disposed of corpses at that time, right? You've escaped. Later, you disbanded the society and agreed not to talk about it again. Also because of this incident, Miss Liu Yi should no longer have a way to face the corpse, so she went to Italy, am I right? ”

Liu Yi raised her head and looked at Li Jing, and suddenly smiled, still with crooked eyes, but I couldn't read the smile in it anymore.
