Chapter 5: Partialism

  Wu Hui took over Fang You's words, "Leg fetishism is a type of fetishism in sexual preference disorders."

  Fang You heard Wu Hui's words and immediately took out his notebook, seriously taking note of "sexual preference disorder? fetishism?"

  Wu Hui saw Fang You like a student, every time he talked about something in the field of psychology, he always held a small notebook and seriously took notes. "Fetishism is characterized by a special fondness for objects specifically used by the opposite sex, such as women's intimate clothing and accessories, which can cause sexual arousal. Some people are also particularly interested in certain parts of the female body, such as hands, feet, hair, etc., which we call 'partialism'. Just like Fang You said earlier, the murderer seems to have a special interest in legs."

  Guo Yining thought for a moment, if the murderer really liked the victim's legs, then this could be another motive for his murder. "So, is the murderer a sexual deviant?"

  Wu Hui shook his head, "If he was a sex preference disorder patient, then he shouldn't be the murderer."

  Wang Hua was somewhat puzzled, saying that the murderer was Wu Hui, and the murderer was not who Wu Hui said it was. He just couldn't stand this kind of self-righteous person. He didn't understand why Captain Guo had brought an outsider here to participate in the case. "What's going on? You're the one talking all the time, so you tell me who the murderer is?"

  Wu Hui knew that Wang Hua didn't like him, but he didn't want to argue with someone who didn't understand him at all. However, his not getting angry didn't mean that the other person wasn't angry.

  "What do you mean by that? Are you suspecting Wu Hui? If you're suspicious, you can tell Captain Guo, don't make us stay here like we're eager to. Zhang Qiang had long been displeased with Wang Hua, who always spoke in a sarcastic tone when talking to Wu Hui, and seemed to have some hidden resentment, speaking in a nagging manner."

  "What's wrong, I didn't say anything wrong, you're not cops, what makes you stay here?" Wang Hua is a Northeasterner, with a quick temper, and after a few words, he wants to fight, and it's not like he's talking to you, what are you doing standing there?

  "It seems like the young master wants to stay here, Wu Hui, let's go. Since we're not welcome here, why should we still stay?" Zhang Qiang saw the tall and majestic Wang Hua stand up, pull Wu Hui who was beside him, and prepare to leave.

  "Wang Hua! Sit down for me!" The discussion of the case was originally going well, but somehow it ended up in a quarrel. Guo Yining felt somewhat annoyed.

  "Captain Guo, they..." Wang Hua heard Guo Yining's shout and knew that Captain Guo was angry, so he quickly explained.

  "Shut up!" Before Wang Hua could explain, Guo Yining interrupted him, "Wu Hui is my invited consultant, do you have any opinions? Are you going to drive me out too?"

  "No, Captain Guo, I didn't mean that... actually, I just..." Wang Hua was a rough man and spoke without thinking, as long as the captain told him to do something, he would do it.

  Wu Hui felt that if he didn't speak up, the meeting would not be able to proceed. "I know, Wang Hua is also anxious because of the case. You old men, just say what you want to say, I like it. Zhang Qiang, don't make trouble, sit quietly and don't talk nonsense!"

  When Guo Yining asked Wang Hua to sit down, Zhang Qiang had already stood up. After all, Guo Yining was the captain and still had a way to control the situation. Moreover, Wu Hui had spoken up, so even if he didn't like Wang Hua, he could only continue sitting next to Wu Hui, silently seething with anger.

  "Wang Hua, aren't you going to apologize to Wu Hui?" This matter was originally Wang Hua's fault, and Guo Yining felt that Wang Hua needed to apologize to Wu Hui.

  "Why should I apologize? I didn't say anything!" Let him apologize, Wang Hua didn't think he had done anything wrong, so he wouldn't.

  Zhang Qiang heard Wang Hua say that and wanted to argue with him again, Wu Hui hastily grabbed Zhang Qiang's arm and pressed it down, hoping he wouldn't speak again. Although Zhang Qiang was still fuming, he restrained himself and didn't utter a word.

  "Bang!" Guo Yining let out a loud slap on the table, making Wang Hua jump up from his seat. "Apologize if you have to apologize, what's with all the nonsense?!"

  Now time is pressing, Wu Hui wants to quickly find out who sent him the card, he doesn't want any more trouble, "Officer Guo, if you continue like this I won't be able to stay here, besides Wang Hua didn't do anything wrong, let's not talk about these things anymore, discussing the case is more important."

  "We'll settle the score later!" Seeing Wu Hui say this, Guo Yining couldn't say anything else and angrily pointed at Wang Hua with her hand. This guy was good in every way, but his temper was just too stubborn.

  Fang You and Yang Rong were already frightened silly. They couldn't understand what was wrong with Wang Hua, who was usually quite lovely but had become like this today.

  Fang Youjian saw that Wang Hua was no longer speaking, so he came out to mediate and change the subject. "Oh, right, where were we just now? Ah yes, Wu Ge, why did you say the murderer wasn't a sex offender?"

  Wu Hui didn't take Wang Hua's words to heart, he thought it was unnecessary. "The behavior of sexual preference disorder and sex offenders are very similar, we need to distinguish between the two."

  Yang Rong saw that several people had quieted down and were no longer making a fuss, so she also hastily followed Fang You to mediate and respond, "What's the difference between them?"

  Wu Hui adjusted his glasses and continued: "Firstly, from the perspective of behavioral motivation, sex offenders commit crimes due to moral decay, which is entirely shaped by postnatal environmental factors. The sexual offenses committed by individuals with paraphilic disorders are a deviation in their psychosexual development, influenced by both postnatal environmental factors and innate qualities."

  Yang Rong nodded seemingly understanding yet not quite, "Oh, I see. And then what?"

  "Wu Hui said again: 'Secondly, the peeping, touching and rubbing behaviors of sex offenders are just the first step in probing the victim. If the victim does not dare to expose or resist, they will have further attacks. For those with sexual preference disorders, these early-stage activities have replaced the need for further attack behavior. As a result, they have already obtained sexual satisfaction at that time and rarely have further attack behavior.'"

  Guo Yining understood why Wu Hui said the murderer and the sex offender were not the same person, "So you think the murderer might be someone else?"

  Wu Hui nodded, "Not bad, there's another difference. Before committing a crime, sex offenders have a plan and after committing the crime, they know how to hide and create a false image. The sexual offenses of those with paraphilic disorders are often impulsive, an irresistible compulsion, their plans are not thorough."

  "So you're saying that one of them committed a sex crime and then another person appeared and killed them, is that what you mean?" Guo Yining found it hard to believe.

  Although it's hard to believe, Wu Hui can be certain of one thing: "The person who actually carried out the murder is the real culprit. He simply used a sex offender with a preference for homosexuality to mislead our investigation."

  Through Wu Hui's explanation, Fang You finally understood "In other words, the sex offender had followed the victim many times before. As long as we find the surveillance footage belonging to the victim, we will definitely be able to find the person who was following them, right?"

  Yang Rong said with some excitement: "That's right, if we find this pervert, maybe we can track down the killer's trail."

  The general idea is out, Guo Yining immediately arranged the action. "Okay, Yang Rong and Fang You go check who Zhou Linlin had contact with before her death. Wang Hua, you go check again if there are any surveillance cameras in the suburbs that can find Chen Yiling's sisters' images before their death, especially ask if the two sisters have been followed recently."

  "Yes!" Several people gathered together and set off immediately.

  Guo Yining saw Zhang Qiang sitting there still looking angry, walked over and sat down beside him, "What's wrong, still angry?"

  Zhang Qiang turned his body around, with his back to Guo Yining, "I don't dare, this is a serious case investigation department, I don't dare to be reckless, what if you catch me, I won't be able to get away with it."

  Guo Yining couldn't help but glance at Wu Hui with a hint of amusement, "This Zhang Qiang is really something, still acting like a kid at his age," she said. "Don't be angry, actually Wang Hua didn't mean any harm, he's just someone who speaks his mind and often offends people, but as a person, he's actually quite good. If he wasn't, I wouldn't have let him stay in the Major Crimes Investigation Unit, right?"

  Zhang Qiang originally thought it was no big deal, but for some reason, he couldn't help getting angrier and angrier. "You say what you want, besides, he didn't do anything to me."

  "Captain Guo, don't spoil him, what's with all the fuss? If you have something to attend to, just go ahead and take care of it, no need to worry about us, we won't wander off." Wu Hui noticed that Guo Yining kept glancing at his watch from time to time, knowing he had an appointment.

  "Alright, I still have something to attend to, I'll be back in a bit, you guys don't wander off." Guo Yining knew that Wu Hui was observant of minute details, and indeed he did have some matters to take care of.

  "Alright." Wu Hui saw Guo Yining leave, turned his head to look at Zhang Qiang, "Don't be angry anymore, we still have important things to do now, don't waste time arguing with others."

  After hearing Wu Hui say this, Zhang Qiang became even more unhappy. He wasn't arguing with Wang Hua because of his own affairs, but because of Wu Hui. Just as he was about to speak up, Wu Hui hastily waved his hand and interrupted Zhang Qiang's words, knowing why Zhang Qiang was angry.

  Zhang Qiang saw Wu Hui's indifferent expression and had no choice but to shut his mouth and stop talking.

  The office was left with only the two of them, at this time Wu Hui had his hands clasped in front of his chest, sitting there motionless. He wanted to think clearly, what was the purpose of the person who sent the card? Could it be that he was really the true culprit of the "1225 Christmas Murder Case" five years ago? If so, why did he disappear for so many years and reappear at this moment?

  What is he doing this time, is he showing off to Wu Hui or challenging him? And is Jing Ran still in his hands? Thinking of Jing Ran, Wu Hui's eyebrows furrowed tightly. For so many years, he had no news of Jing Ran, was she okay?
