Han Bin's guess was right. The forensic doctor's conclusion was carbon monoxide poisoning and chronic hypoxia.
Because the body was charred, the exact time of death could not be determined.
Han Bin told Li Cunrong his previous speculation.
Li Cunrong was also an experienced criminal investigator. He also felt that the victim might have been tied up before he died. Most people would not lie down straight when they slept, but he had doubts in his heart.
"Brother Han, even if the victim was tied up before he died, he should still be able to move. Why didn't he move to the door or the window to ask for help? Why did he just lie down and wait for death?"
Han Bin analyzed. "If I'm not wrong, he must have been electrocuted before he died. He didn't lie down and wait for death, but was electrocuted."
"The body was already charred. Even the forensic doctor couldn't tell that it was an electric shock. How do you know?"
"In the murder case we investigated before, the victim was electrocuted and then strangled to death by the murderer with a belt," Han Bin explained.
"So, it's likely to be a serial murder case?"
Han Bin said seriously. "At present, there is not enough evidence to prove that these two cases are directly related, but my personal speculation is that it is likely to be a serial murder case."
It was already past eleven at night, and there were still many onlookers standing at the entrance of the neighborhood.
Han Bin and Li Cunrong discussed for a while. Li Cunrong stayed at the scene to visit the surrounding people and neighbors.
Han Bin went to the hospital to visit Jiang Kunshan and his wife.
In the car, Han Bin reported the situation to Ma Jingbo and told him his speculation.
As for whether or not to set up a joint task force, it was up to Ma Jingbo.
Wang Ting also sent two WeChat messages to Han Bin. The content was simple. "One was sent around ten at night. 'Have you arrived at Gao City? Be careful. '"
"The second was, 'I'm sleepy. I'm going to sleep first. Let me know you're safe when you see WeChat.'"
Han Bin felt warmth in his heart and replied to Wang Ting with a voice message. "I've finished investigating the scene and am on my way to visit the injured. Good night."
Bao Xing asked as he drove, "Team Leader, do you think this case is related to Li Yuan's death?"
Han Bin didn't answer. Instead, he asked, "Would you believe me if I said it's nothing and that it's just a coincidence?"
"Hehe." Bao Xing chuckled. "If you say it's fine, then I'll definitely believe you."
Han Bin lit a cigarette and took a drag. "There's definitely a connection, but it's hard to say what the connection is and whether it's the same murderer."
"Assuming it's the same murderer, the murderer's motive for killing is likely to be to avenge Chen Shaoyan."
"Then Cai Jing is even more suspicious. The most important thing now is to find Cai Jing's whereabouts."
"What I'm worried about now is, if this is really the work of a serial killer, will there be a third victim?"
There was a moment of silence in the car before Li Qin continued, "The drowning case involved a total of four people. Chen Shaoyan died unjustly, followed by Li Yuan's murder. The victim of this fraud case is most likely Jiang Huawen, so there's only one person left alive — Hong Xin."
"At first, I guessed that Hong Xin might be the murderer, but judging from the current situation, Hong Xin doesn't have enough of a motive to kill. I think we can investigate further to see if Hong Xin has an alibi to completely eliminate Hong Xin as a suspect. "
Li Qin changed the topic and said with a solemn expression, "If Hong Xin isn't the murderer, then she's most likely the chosen third victim."
Bao Xing had a different opinion and said, "Hong Xin is different from Li Yuan and Jiang Huawen. Chen Shaoyan didn't die to save her, so the possibility of him killing her shouldn't be high."
Li Qin shook her head. "The murderer has killed two people in a row and is already in a frenzy. It's impossible for him to be as rational as you are."
Han Bin flicked the ash off his cigarette. Both of them made sense, but Han Bin didn't rush to a conclusion. First, he needed the forensic doctor to confirm whether the victim was Jiang Huawen or not.
If the victim wasn't Jiang Huawen, then the previous inference wouldn't be valid.
The case would also become more complicated.
…
Gao City People's Hospital.
In the burn ward.
Unlike the noise and wailing he had imagined, the corridor of the burn ward was quieter. Only a faint moaning could be heard.
There were two police officers guarding the corridor. After Han Bin showed them his police badge, he asked about the situation.
Jiang Kunshan's injuries had just been treated and he had been injected with anesthetic, temporarily suppressing the pain.
Zhao Chunlian was still in the emergency room.
Han Bin walked into the ward and a strong smell of medicine floated in the air. A man was lying on the bed, his body wrapped in layers of white gauze. It was the owner of Huawen Supermarket, Jiang Kunshan. His eyes were closed and he was moaning in pain.
Although his voice wasn't loud, it was dragged out and made people's scalps go numb.
At that moment, the attending doctor walked over. It was a female doctor in her forties.
The female doctor glanced at Han Bin and the others. "What's the matter? Why are there so many people all of a sudden? Hurry up and leave, only two people can enter at most. "
Han Bin gestured for the others to leave, leaving only Bao Xing behind. He then showed his police badge. "Hello, I'm Han Bin from the city's criminal investigation team. I'm looking for Jiang Kunshan to understand the situation."
"Uh." After hearing the voice, Jiang Kunshan opened his eyes and his gaze fell on Han Bin. "Officer Han, you're Officer Han. Where's my son? How's my son? "
Han Bin ignored him and asked the female doctor beside him, "May I ask if Jiang Kunshan's current physical condition allows him to take a statement?"
Before the female doctor could answer, Jiang Kunshan took the initiative and said, "Yes, I can take a statement. Officer Han, I'm willing to cooperate with the police investigation."
The female doctor also ignored Jiang Kunshan. "I'm Jiang Kunshan's attending doctor, Liu Yaping. Although his injuries aren't serious, he's still in a critical period of recovery. I don't recommend him to take a statement now. It's best if …"
Jiang Kunshan interrupted her directly, "I'm fine. I want to take a statement. Officer Han, don't listen to the doctor. I'm really fine. I'm completely fine."
Liu Yaping's expression was a little ugly. She glanced at Jiang Kunshan and said to Han Bin, "If the patient insists on taking a statement, I suggest that he don't take more than half an hour."
"Thank you," Han Bin said politely.
Liu Yaping nodded and left the ward with her hands in her coat pockets.
Jiang Kunshan asked impatiently, "Officer Han, have you found my son? How's his current condition? "
"We're not sure about your son's condition." Han Bin was not lying. As long as the DNA test results were not out, no one could guarantee that the person who died at home was not Jiang Huawen.
"What do you mean we're not sure?!" Jiang Kunshan shouted.
"Jiang Kunshan, if you're emotionally unstable, we can come back later to avoid affecting your health," Han Bin said.
"I'm not emotionally unstable. I just want to know where my son is."
Bao Xing asked, "Jiang Kunshan, have you forgotten that we went to the supermarket today to look for your son, but we didn't find him. We're here now to learn more about your son from you so that the police can determine where your son is. "
Jiang Kunshan quickly said, "I'm sorry, I lied. When you came today, I knew where my son was. He was at home."
"Why did you lie to the police?"
Jiang Kunshan sighed. He had no scruples now and said, "I don't want to cause trouble."
"What trouble?"
"As you said, twelve years ago, my son fell into the river and was saved by Chen Shaoyan. However, that short-lived Chen Shaoyan didn't come up himself. We've always been afraid that the Chen family would come looking for trouble, so when you mentioned this matter, we were against it from the bottom of our hearts. "
"The Chen family came to look for you before?"
Jiang Kunshan looked angry. "Why didn't they? First, Chen Shaoyan's parents came to look for trouble. Later, Chen Shaoyan's parents didn't come. Then, it was Chen Shaohuan, that bad woman. She insisted that my son killed her cousin and often came to our supermarket, asking us to pay. If we didn't pay, she wouldn't let us do business."
Han Bin noted it down in his notebook. "Chen Shaohuan is Chen Baifeng's daughter?"
"Yes, that old guy also made a scene after he was discharged from the hospital. He insisted that his brother, Chen Baishi, was also killed by our family. Don't you think I'm wronged? It's obvious that he's trying to blackmail our family." Jiang Kunshan's voice was so loud that it tore the wounds on his body and he grimaced in pain.
"What does your son do for a living?"
"He used to work in sales. Last month, his company closed down. Now he can't do anything. He just rests at home and doesn't want to help in the supermarket. " Speaking of this, Jiang Kunshan asked, "Officer Han, do you know where my son is or not?"
"We really can't confirm your son's whereabouts. However, we found a corpse in your bedroom. We still can't confirm the identity of the corpse," Han Bin said.
Jiang Kunshan was anxious. "How can you not be sure? You police can't even identify a person. Where's the photo? I can recognize my son. Let me see."
Han Bin hesitated for a moment. In the end, he still didn't let him see the photo. Jiang Kunshan was injured now. If something happened to his body due to the stimulation, Han Bin didn't want to get himself into trouble.
"You should know the situation at that time. After the gas explosion, there was a big fire in the house. Everything was burnt beyond recognition."
Hearing Han Bin's words, how could Jiang Kunshan not understand? He shouted, "Son, my poor son. You are still so young. How could you die so miserably!"
Han Bin didn't stop him. He waited for him to cry for a while before comforting him. "No one can be sure whether the corpse is Jiang Huawen's or not. We still need to wait for the identification results to come out. What you need to do now is to rest and cooperate with the police. Excessive sadness won't do you any good."
"Sob … You make it sound so easy. My son is dead. How can I not be sad?"
Jiang Kunshan's cries could be heard outside.
"Creak …" The door creaked and the female doctor, Liu Yaping, walked in.
"What's going on? The patient's injury hasn't recovered yet. He can't be too emotional."
Han Bin looked apologetic. "Doctor Liu, I'm sorry to have caused you trouble. We'll leave now. We'll come back when Jiang Kunshan's condition gets better. "
"Don't go. Please don't go." Seeing this scene, Jiang Kunshan thought of the scene in the supermarket. If his attitude had been better and he had actively cooperated with the police, maybe tonight's incident wouldn't have happened.
"Officer Han, I have something else to tell you. I know who wants to kill my son. I know!" Jiang Kunshan shouted.
"Who?"
"Chen Shaohuan. It must be that woman. She knows where our supermarket is and where we live. She must be the one who wants to take revenge on our family," Jiang Kunshan said firmly.
Han Bin asked, "Why does Chen Shaohuan want to take revenge on your family? Is it because of Chen Shaoyan?"
Jiang Kunshan sighed. "At first, it was because of Chen Shaoyan. Later, she caused trouble more and more, and there was hatred between our two families. Once, she came to the supermarket to cause trouble, and my wife fought with her. She was beaten up by my wife."
"Chen Shaohuan is not someone who is easy to deal with. After returning home, she called her husband and her husband's relatives to cause trouble at our house. They even injured our husband and wife and took the trouble to the police station."
"Chen Shaohuan is a primary school teacher with a decent job. She was detained because of the fight and was punished by the school. I heard that she was fired at the end of last year. She must be holding a grudge against our family!"
"Does your son have any contact with Li Yuan?"
"Li Yuan? Who is she? "
"The student who fell into the river with your son."
"I don't think so. Anyway, I haven't heard of her. Why?"
"Li Yuan was also killed a few days ago. We suspect that it might be related to the drowning case. That's why we want to find out more about the situation with your son. At the same time, we want to remind him to be careful," Han Bin said.
Jiang Kunshan was stunned. He widened his eyes and asked, "In other words, you're not here to cause trouble for my family. You're here to protect my son."
"We were just speculating at the time. After all, Li Yuan's family has left Gao Cheng for many years."
Jiang Kunshan closed his eyes and murmured softly, "It's me. I killed my son. I deserve to die. I really deserve to die!"
"You don't have to blame yourself too much. No one expected this to happen. We, the police, will do our best to investigate and find the suspect who hurt your family. We'll seek justice for you. "Han Bin advised.
Jiang Kunshan shook his head and muttered to himself, "Why did this happen? Why?"
Seeing that Jiang Kunshan's emotions were a little unstable, Han Bin waited for a few minutes before continuing to ask, "Jiang Kunshan, do you know Cai Jing?"
Jiang Kunshan frowned. "Who?"
"Chen Shaoyan's mother, Cai Jing."
"Chen Shaoyan's mother …" Jiang Kunshan murmured and fell into his memories. After a while, he said, "I remember now. She came to our house a few times. The last time was with Chen Shaohuan. She said that her husband was hospitalized and his condition was very serious. She asked us to help pay for the medical expenses."
"Our family's financial situation is average. How could we afford to help outsiders? My wife and I chased them away. I still remember what happened that day. It was autumn. She was wearing a maroon coat. Before she left, she glanced at me. I can't forget that look … despair and anger …"
