The four dishes and one soup taste quite good and are authentic Shandong cuisine. Han Xu picked up a piece of sweet and sour carp and put it into Song Jiaer's bowl. Then he looked at Chengzi and said, "Did you notice anything?" Cheng Zi forced himself to put down the food in his mouth and muttered, "There is no comparison. You should give me a portrait of the suspect, otherwise everyone will look like the murderer to me!" Han Xu knew that Chengzi was telling the truth, but with the clues he currently had, it was really impossible to trace the murderer. If he told the truth, wouldn't it mislead the direction of the investigation? Psychological profiling is a double-edged sword. Once the analysis is wrong, it will bring big trouble to the investigation of the case. Therefore, Han Xu will not profile casually without being 70 or 80% sure. Song Jiaer picked up the fish pieces in the bowl and said, "In the morning, I studied the line of blood characters. From the height above the ground, I can roughly infer that the murderer is between and meters tall. The font is very skewed, like On purpose, but nine times out of ten it’s a male.” Hearing what Song Jiaer said, Han Xu nodded, "The murderer has a strong sense of counter-investigation. The bloody words may have been written with his left hand. I also think the murderer is a male, or multiple people committed the crime, kidnapping, imprisoning, and killing." Hiding a corpse requires some strength. Of course, I prefer to do it alone. This kind of serial murderer does not need to work with others. " "Single person, male, height to ." Chengzi wrote down the two people's conclusions in the memo on his mobile phone. At least he had a general direction and wouldn't be too blind. "Do you two have anything to add?" "Actually, I think this Chen Yunlang has a major suspicion." Han Xu targeted a suspect for the first time. Xiao Xiao couldn't help but say after hearing this, "Him? He's so weak, it's impossible. I've been in contact with this Chen Yunlang, he doesn't dare to kill anyone."
"The main reason I suspect him is that he has a motive for murder and is one of the people who knows your sister best." "The police must have investigated him, and maybe there is an alibi." Xiao Xiao said. Han Xu nodded and said, "I have read the file on your sister's disappearance. This Chen Yunlang does have an alibi. At around 21:30 on the night of April 2, he appeared in a bar called Birchwood in the old city. There are many People can prove it.” "Then you still doubt him?" Xiao Xiao asked puzzledly. "It takes about an hour to drive from Binhe Park to Birchwood Bar. If you take a shortcut, it will take less time. Have you ever met Chen Yunlang? Do you think he is a person who likes to hang out in bars?" Han Xu chewed. A vegetarian meatball, sweet and delicious. Xiao Xiao shook his head, "No, I haven't heard my sister say that he likes to drink before." "So, I suspect that he is deliberately creating his own alibi." Han Xu put down his chopsticks and leaned back on his chair. Song Jiaer couldn't help but ask, "You mean, this Chen Yunlang deliberately found a bar far away?" "I asked Lao Zhang to check the address of Chen Yunlang, which is on Gulou Street." Han Xu added. Xiao Xiao was confused. "When my sister disappeared, the last call was at 21:25. Chen Yunlang had already run so far away. How could he kidnap my sister?" Han Xu looked at Xiao Xiao and asked, "The last phone call you made, can you remember what I said? Is there anything wrong?" "No," Xiao Xiao was completely confused now. "Can you remember the complete content?" Han Xu seemed to be grasping the key points. Xiao Xiao rubbed her temples and thought carefully for a few minutes before saying, "After the call was connected that day, it was my sister who spoke first. She said she was running at night in Binhe Park. I asked her when she would be back, and she only said a few words. I said the word right away, and then I asked her where she would go shopping tomorrow. She said she had something to do, and then she hung up the phone. If you want to say something strange, there is no problem with your voice, but the interval seems to be a bit long. My sister usually speaks in a hasty manner, so she would pause for a second or two in every sentence. " I ran at night in Riverside Park! immediately! If something goes wrong, we’ll talk about it later! Xiao Ya only had three sentences in the entire call, totaling 17 words in total, and they were all short sentences!
Han Xu typed these sentences into a note on his mobile phone and showed them to everyone, "Look, these sentences are very short, concise and can be applied to many occasions." Chengzi stopped his chopsticks for the first time and said in surprise, "Don't tell me, it's true. So what does this prove?" "Recording?!" Song Jiaer seemed to have caught the key point of what Han Xu wanted to say. Han Xu smiled and stopped pretending, "I suspect that the call you made, Xiao Xiao, helped the murderer create an alibi. Of course, if you didn't call, he would just find an acquaintance and call him using Xiao Ya's cell phone. " Xiao Xiao's face turned pale, "The murderer took my sister's cell phone and used a recording to talk to me?!" Han Xu nodded slightly, "This is very likely." "How is this possible? Could it be that Xiao Xiao couldn't hear it?" Chengzi understood clearly and pointed out the biggest contradiction. It is easy to distinguish between the real voice and the recording. Song Jiaer explained, "If the recording has undergone secondary processing and some technical means are added, it will be difficult to hear it." "This guy is too cunning." Cheng Zi stood up and said, "Are you sure it was this kid who did it? I'll catch him right now!" "Sit down, you want to go to heaven!" Han Xu glared at Chengzi, "These are just speculations without substantial evidence." Xiao Xiao obviously couldn't accept it, and his eyes were red. Song Jiaer stood up and stood behind her, pressing her shoulders to comfort her. Just as Han Xu said, these are just based on speculation. There is no evidence. Time has erased the traces of the evidence that once existed. This is exactly where the murderer is smartest. First, kidnapping, imprisonment, and then killing and hiding the body when he is out of danger. Everything the murderer did was to avoid the police's sight. Even if he was found later, a lot of evidence was missing and could not be closed into a circle, forming a perfect crime. Han Xu even felt powerless. What if he knew who the murderer was? For the first time, he felt an invisible sense of oppression! It was as if the murderer hiding in the dark was mocking him mercilessly! "Since this Chen Yunlang is a major suspect, we will keep an eye on him. I don't believe that he has three heads and six arms and will not make any mistakes?" Song Jiaer also met this murderer for the first time, and encouraged everyone. Han Xu nodded and said, "Let's eat first. After eating, I will call Captain Qin to report the case and see what he thinks." If you have any difficulties, find the leader! If there are no difficulties, create them and find a leader!
