Chapter Sixteen: Finding Clues

  Wu Hui rushed back to receive a call from Guo Yining, who had concluded from the cat's corpse yesterday that the method and force used were the same as those of the serial killer in previous cases. Unfortunately, no skin tissue was obtained from the cat's body.

  Wu Hui had thought of this conclusion earlier, he inferred that since the murderer had pulled out all the cat's claws, it could be deduced that during the process of abusing the cat, he should have been scratched by the cat. So as long as they investigated in the villa area to see if there was anyone who had been scratched by a cat.

  Guo Yining and Fang You spent a day visiting the villa area, going door-to-door to collect evidence, but in the end, they didn't find any clues. Guo Yining suspected that it might not be someone from the villa area who did it, but rather someone had thrown the cat's body into the unmonitored villa area.

  However, Fang had seen the surveillance footage of the villa area. After the cat entered the monitored area, it did not come out again. During this time, no one was seen carrying a large package or anything similar from the villa area, and the cars that left the villa area did not return until evening, making it even more impossible for them to be the cat abusers.

  So they inferred that the cat abuser must still be in the villa area, but didn't know why they hadn't found him. Wu Hui and Fang You reviewed the surveillance footage again and discovered a person they had overlooked - Liu Jianjun's son, Liu Hao.

  On the same day, Liu Jianjun drove away. In the surveillance footage, it can be seen that the driver was Liu Chong, and the person sitting in the back is not clear, but from the outline, it can be seen that there are two people. With this discovery, Guo Yining and Fang You came to Liu Jianjun's company again, and coincidentally met Liu Chong who was preparing to leave at the entrance of the building.

  Liu Chong saw that Guo Yining was a bit uneasy, anxiously looking up at the building, worried about being seen by Liu Jianjun, so he took the two to the back door of the company building.

  When Guo Yining came to his doorstep again, Liu Chong felt a bit disgusted. Although Liu Jianjun and Yang Liu had an unclear relationship, Yang Liu was already dead, and he still wanted to continue living. Being a driver for Liu Jianjun was a good job, and he didn't want to be fired. "What are you doing here again? I've already told you everything I know last time. I don't want to lose this job."

  Guo Yining knew Liu Chong's concerns, "Don't worry, this time we will only ask one question, and after asking, we will leave."

  Liu Chong somewhat impatiently waved his hand, he didn't want to have too much contact with the police. "Alright, what's this about? Ask quickly, I still have things to do."

  Guo Yining didn't bother to argue with him either. "This morning when you drove out, besides picking up Liu Jianjun, who else was there?"

  Just as Liu Chong was about to speak, the back door of the building opened and a janitor came out to dump trash. Seeing three people standing by the back door, she took a deliberate glance at them. Liu Chong worried that the janitor would recognize him, so he shifted his body sideways, turning his back on her. "Mr. Liu and Liu Hua, today Liu Hua overslept and was late for school, so Mr. Liu is sending him off."

  Behind the building, there is a very large trash can. All the trash from this building is placed in this trash can. At first, no one noticed it was there until the janitor emptied the trash. "Did Liu Jianjun often take Liu Hao to school before?"

  The janitor emptied the trash and took another look at the three people standing together, then opened the back door and walked in. Seeing the janitor leave, Liu Chong was still a bit worried. If Liu Jianjun knew that he often talked about their family affairs with them, Liu Jianjun would definitely be unhappy. "No, Liu Hao doesn't like Liu Jianjun to appear at their school. This is the first time. Is there anything else? No, I'm leaving."

  Since Fang Youjian saw that Guo Yining had nothing more to ask, he put away his notebook and said to Liu Chong: "Alright, you can go."

  "He's Yang Liu's boyfriend? Something like this happened and he still follows Liu Jianjun, I really look down on him." Fang You found out about Liu Chong and Yang Liu from Guo Yining, and was given such a big green hat, but he acted as if nothing had happened.

  As for Liu Chong's approach, Guo Yining somewhat understood, "He is actually a sensible person, Yang Liu died, but he is still alive, he needs this job, people are always selfish, thinking more about themselves, nothing wrong with that, let's go take a look at Liu Hua's school."

  Fang You drove with Guo Yining to Liu Hua's school, which was Lincheng High School, also known as Lincheng No. 2 Middle School. Now that Liu Hua is in his third year of high school, the academic atmosphere is very tense. When Guo Yining appeared in the head teacher's office, Wu Hui happened to be talking to the head teacher.

  "You're pretty quick, have you asked anything?" The class teacher had a class next period and couldn't accept Guo Yining's inquiry. Wu Hui happened to ask the questions that needed to be asked, so Guo Yining decided to ask Wu Hui instead.

  Early in the morning, Wu Hui saw two people in the car on the monitor and he was sure that one of them was Liu Hao. Although he had never seen Liu Hao before, subconsciously, he felt that there were many things about Liu Hao worth exploring.

  So when Guo Yining and others went to find Liu Chong, he took a taxi to Lincheng No. 2 Middle School, found the class where Liu Hao was studying, and found the head teacher of that class.

  Yesterday morning, Liu Hua indeed skipped two classes, but because his father personally called to ask for a sick leave for him, the head teacher did not pursue it further. Liu Hua is a particularly quiet boy in class, with few friends, attending classes on time every day, and after school, he does not play basketball with his classmates, but goes home directly. His grades have always been very good, and he is one of the main focuses for the college entrance examination, and it should be no problem to get a good score in the first-tier university.

  On November 9th, Monday, Liu Haosheng took a sick leave for one day and returned to school on the 10th, which coincides with the time of death of the fourth victim. Looking back at the times of death of the other three victims, they all occurred during holidays or weekends, and in terms of timing, only Liu Haosheng's alibi is suspicious.

  Wu Hui also observed that during class, Liu Hua was very careful to protect his left arm, and it should be injured.

  Guo Yining called Liu Hao out of the classroom. Liu Hao looked at the three strangers standing in front of him, somewhat perplexed. "Who are you? I don't know you."

  "Don't be afraid, we are police. May I take a look at your left arm?" Fang pointed to Liu Hao's left arm.

  As for Fang You's words, Liu Huan didn't feel afraid at all and responded calmly, "What's the matter?"

  Liu Hua's calmness made Guo Yining even more certain that Liu Hua was not as quiet and honest as he seemed on the surface. "Nothing, just taking a look at your arm, it seems to be injured."

  Liu Huan looked down at his left arm, not even rolling up his sleeve, and smiled slightly, "I don't need the police to check my injured arm, that's a waste of resources, isn't it?"

  Liu Huan only smiled slightly, but the slight upward curve of his mouth made Wu Hui's eyes ache. This feeling suddenly produced a strange anger in his heart, and his smile was too dazzling.

  Fang You didn't want to bother with Liu Huan, so he directly grabbed his left hand and rolled up the thick school uniform sleeve. When the sleeve was rolled up, several people took a cold breath, revealing a large area of scalding on Liu Huan's left arm, with blisters all over it that were shocking to see.

  Liu Huan gently pulled his sleeve down to cover the wound. "Officer, is there anything else? If not, I need to get back to class."

  Three people didn't say anything, Liu Hua turned around and returned to the classroom. The third-year students were all studying with their heads down, no one noticed that Liu Hua had gone out and come back in, as if nothing had happened. Liu Hua returned to his seat, lowered his head and continued doing the mock exam paper he hadn't finished.

  "How could it be like this?" Fang You was still reeling from the shock of earlier, such a large area of burns, and yet Liu Huan was still able to attend classes normally. This child's inner strength must be incredibly powerful.

  "The more you try to cover up, the more obvious it becomes. Captain Guo, perform a forensic examination on him. Although he has covered up his wounds, I believe that the hidden scratch marks will definitely contain the cat's DNA." Although Liu Hao's left arm was scalded beyond recognition, some wounds are impossible to conceal.

  There were some unbelievable looks at Wu Hui, how could Liu Hao not be such a ruthless person? "You mean to say that Liu Hao, in order to cover up the wound from being scratched by the cat, intentionally scalded his entire arm? This is unlikely, he's still a student, isn't it too much for him?"

  "After the evidence is obtained, it will be known." Wu Hui did not answer Fang You's question. What he was most interested in now was Liu Hao. As long as he could investigate the injury on Liu Hao's arm, everything that seemed impossible would become possible.

  When Liu Jianjun learned that the police had brought Liu Hao back for questioning due to the serial murder case that had caused a stir in the city, he arrived at the police station with his lawyer. Seeing his angry expression, Guo Yining also knew that he was not an easy person to deal with.

  "This is the lawyer I've hired for Liu Huan, if you have anything to ask, ask the lawyer, Liu Huan won't answer any of your questions." Standing next to Liu Jianjun was a man in his forties with slightly thinning hair, small eyes, and thin lips, looking very calculating.

  "My name is Wang Tuo, here's my ID." Wang Tuo smiled and walked forward, handing his ID to Guo Yining.

  Guo Yining looked at them and led the two to the interrogation room. "According to Article 56 of the Juvenile Protection Law, when interrogating or trying a juvenile suspect or defendant, or questioning a juvenile witness or victim, the legal representative or other personnel must be notified in accordance with the Criminal Procedure Law. Liu Hao is a minor, so it's right that you're here. We just want to collect his DNA now, and I don't think the lawyer will refuse, will he?"

  "Of course, helping the police crack cases is a duty we citizens should fulfill."

  Liu Heng was sitting in the chair, heard the sound of opening the door, looked up and saw Liu Jianjun leading a man to come in, Liu Heng did not speak, and lowered his head again.

  Seeing Liu Hui's indifferent attitude, Liu Jianjun was somewhat angry. It would have been fine at home, but now that they were at the police station, he was still acting this way. If he had known earlier, he wouldn't have hired a lawyer for him. However, thinking about it, if Liu Hui really committed a crime, it would definitely have a huge impact on his company. Thinking of this, Liu Jianjun suppressed his anger and walked to Liu Hui's side, "Liu Hui, this is Lawyer Wang. Whatever you say to him, he will definitely help you."
