Room 104, Unit 4, Building B, Xuyuan Xinju, Gulou Street, where Chen Yunlang lives. "It's the third time! This place is too clean!" Song Jiaer's voice was a little tired. There were a lot of things going on recently and she didn't have enough time to rest. Han Xu knew that the people involved in this case were tense in their hearts. He clapped his hands to attract enough attention, and then said, "Everyone, please stop and rest for a few minutes." Chengzi went outside to get two bottles of water and threw them to Han Xu, "No wonder the man named Chen didn't say anything. He was sure that we wouldn't find out anything." Han Xu handed Jia'er a bottle of water and said, "Let's rest for a while. It's such a big place, so there probably won't be many clues." "We finally got the search warrant, but we found nothing. How can we not be laughed at to death when we go back?" Song Jiaer said helplessly. "What's the matter? If Chen Yunlang hid the murder weapon at home, it would be like hell." Han Xu joked, it would be normal if he didn't find it. If he really found any evidence here, it would most likely be the murderer's suspicion. "The murder weapon still hasn't been identified?" Song Jiaer took over. In the forensic identification, the murder weapon is a very critical part. Under normal circumstances, after the murderer pleads guilty, he also needs to find the murder weapon to complete the puzzle before the case can be finalized. Of course, except for special circumstances, such as the murderer throwing the murder weapon into the sea, we can only look back and sigh. Han Xu replied, "Forensic Doctor Hao said that this murder weapon is not particularly sharp, has uneven edges, and is not made of metal. It may have been homemade by the murderer." "Ice?" Thinking of the corpse hidden in the freezer, Song Jiaer couldn't help but lean in that direction.
"I don't rule out this possibility, but I personally don't think it's an ice knife." Han Xu doesn't think the murder weapon is made of ice. After hearing this, Chengzi became interested and took over Song Jiaer's place and asked, "Why?" Han Xu looked at Chengzi and then at Song Jiaer, pretending to be mysterious. "Tell me, stop showing off." Chengzi asked. Han Xu ignored Chengzi and picked up the topic, "The shape is too thin. The ice is polished to look like that. It's too brittle. Let alone stabbing people, it can't even kill a chicken." Song Jiaer's beautiful eyes turned and she thought to herself, the skates were not strong enough. "What about the bone knife?" Chengzi started brainstorming. "Oh, you have such a rich imagination. Is it necessary for Chen Yunlang to make a knife out of bones? What to do with it afterwards, throw it into the sea?" Han Xu responded mercilessly. "How is it impossible? I have seen a movie before, and the bullet was made of bones. When the thing hit the person's body, it exploded, and there was no trace at all." The back of Orange's neck was red and thick. Han Xu smiled and said, "You already said it was a bullet, but what we are discussing now is a knife!" "Is this different?" Chengzi could only quibble. "How can this be the same?" Song Jiaer rolled her eyes at Chengzi, then looked at Han Xu, as if to say, "Hurry up, great detective." Han Xu was silent for a while and then said, "Jia'er's idea just now is very good. If the murderer is Chen Yunlang, what he wants to do most is not to leave any traces. For example, if the murder weapon is made of ice, it will melt easily. There is no trace of this murderous weapon on this earth. We might as well think about it on this basis, what is very sharp, shaped like a knife, and can disappear without a trace? " "I don't study well, so don't fool me. Is there such a thing?" Chengzi was dumbfounded after hearing Han Xu's analysis. "Just because you don't know, it doesn't mean that this thing doesn't exist." Han Xu felt that his idea was absolutely fine, but for a while, he really couldn't think of what it could be that had such heaven-defying properties. "What do you think Chen Yunlang did before? He kept the place clean, even at home. Isn't he a germophobe?" Song Jiaer also gave up discussing the murder weapon and instead talked about the environment here. "It doesn't look like someone with mysophobia. This kind of cleanliness is deliberate, like a habit developed for a long time under some kind of pressure." Han Xu has long been analyzing everything here, including small details such as the owner's living habits. Don't let it go, "Anyone with mysophobia will inevitably be accompanied by obsessive-compulsive disorder. It can also be said that mysophobia is one of the clinical manifestations of obsessive-compulsive disorder. It is divided into two parts: thinking and behavior. You see, the furnishings here are very casual, not obsessive-compulsive." The symptoms of mysophobia were the same at the crime scene, and the murderer did not show strong symptoms of mysophobia. However, when it comes to mysophobia, I think it is still possible. "
Han Xu couldn't help but recall Chen Yunlang's feminine eyes, and then remembered something that often appeared in this case. Obsessive thinking? Freezer? What is the connection between the two? "Hey, what's wrong with you? Why are you in a daze? You're right." Song Jiaer pushed Han Xu and pulled him back from his fugue. Han Xu's eyes gradually became clearer and he said to Song Jiaer, "I think Chen Yunlang has obsessive thinking about the freezer, or it is a kind of obsessive intention." "What do you mean?" Song Jiaer couldn't understand, and Chengzi was even more confused. "But there's no freezer here! That's weird!" Han Xu looked around the place again, but didn't find what he expected. "I'm talking about Detective Han, can you explain it more plainly and understandably?" Song Jiaer became a little angry, her mouth pouting. Han Xu collected his thoughts and then said, "I have seen a case before. The suspect had severe psychological trauma because he was abused as a child. He was particularly insecure and liked to stay in very cramped spaces. This behavior is consistent with claustrophobia. Phobias are the complete opposite.” Song Jiaer seemed to understand, "You mean Chen Yunlang is also such an insecure person, has obsessive-compulsive disorder, and likes to put the victim in the freezer?" "Yes, to be precise, in his subconscious, the cramped space like the freezer is the safest, and he even sleeps in it." Han Xu's statement is easier to understand. "Fuck, what a pervert!" Chengzi was stunned after hearing this. The final summary was appropriate and expressed the thoughts of everyone present. Song Jiaer looked around and asked in confusion, "But there is no freezer here!" "Maybe I'm wrong. These are all random guesses. There is no basis. If Chen Yunlang is not the murderer, he will be wrongly accused to death by me." Han Xu was not sure either. After all, there was only a refrigerator in the kitchen, not a freezer, so this theory was untenable. However, this analysis still made his colleagues around him praise him. Not to mention that it was easy to understand, but just this boldness was not something that ordinary people had. If a large freezer was really found, the weirdness of this case would be outrageous!
