Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Yang Lin nodded and added, "From the crime scene, the murderer chose to dump the body in an abandoned cave and burned the vehicle used in the crime. This series of actions shows that he has a strong anti-detection awareness. This means that he may not be a first-time offender, or he has made a lot of preparations in advance. Combined with his behavior of letting Lao Wang steal the car, I speculate that he may be a meticulous person who has a certain understanding of the criminal process. His motive for committing the crime may not only be for money, but also to cover up other more serious crimes."

Yang Sen continued, "When I investigated the scene, I found that the deceased's belongings were not missing, which shows that the murderer's purpose was not just robbery. If it was for money, he could have taken his belongings after killing Li Jianshe. So, I think the murderer's motive may be revenge, or to prevent Li Jianshe from doing something that is not good for him. For example, Li Jianshe knew a secret of the murderer, which threatened the murderer's interests."

Zhang Kai put down his pen and said, "From a forensic point of view, the fatal injury of the deceased was a severe blow to the head, but there were other injuries before that. This shows that the murderer inflicted more than one injury on Li Jianshe, and this behavior was probably out of strong hatred or some special purpose. Combined with the fibers, parts and other physical evidence found at the scene, I think the environment where the murderer committed the crime may be related to factories and machinery, which may help us narrow the scope of the investigation and further clarify the motive for the crime."

Lu Chuan listened carefully to everyone's speeches and nodded: "Everyone's analysis makes sense. Although the clues we have now point to economic and interest conflicts, the specific situation still needs further investigation and verification. Zhang Hui, you continue to dig deeper into Li Jianshe's economic dealings to see if there are other hidden debts or interests; Wang Shuai, strengthen the investigation of Li Jianshe's factory colleagues and surrounding personnel, especially those who have had conflicts with him, to see if you can find new clues; Yang Lin, Yang Sen, carefully check the crime scene and vehicle wreckage again, there may be key evidence that we have missed; Zhang Kai, you conduct a more detailed examination of the body to see if you can find more clues related to the murderer."

Everyone responded in unison: "Understood!"

After the meeting, Zhang Hui dove into Li Jianshe's financial information. He carefully checked every account, not missing any details. After several hours of hard work, he found that before Li Jianshe's death, he had frequent financial transactions with a man named Sun Hong. Sun Hong was the owner of a small factory, and Li Jianshe had worked part-time as a maintenance worker in his factory. Zhang Hui immediately informed Lu Chuan of this discovery.

After Lu Chuan pondered for a moment, he said, "This Sun Hong is very suspicious. You should immediately investigate his background and whereabouts to find out what he did before and after Li Jianshe's death."

After receiving the order, Zhang Hui quickly launched an investigation. He found that Sun Hong's factory was facing a serious financial crisis recently, and Li Jianshe seemed to have discovered some problems in Sun Hong's factory during his part-time job.

At the same time, Wang Shuai visited the factory where Li Jianshe worked again. He found several of Li Jianshe's colleagues and asked them in detail about their relationship with Li Jianshe and the recent abnormal situation in the factory. A colleague revealed that before Li Jianshe's death, he heard him and Sun Hong arguing on the phone, and Li Jianshe seemed to threaten Sun Hong to expose some things.

Wang Shuai brought this clue back to the police station. After listening to it, Lu Chuan's eyes became more determined: "It seems that Sun Hong is a big suspect. Let's find him first and ask him what happened between him and Li Jianshe."

The police acted quickly and found Sun Hong. When Sun Hong saw the police coming to his door, his face became somewhat calm.

Lu Chuan asked seriously, "Sun Hong, what is your relationship with Li Jianshe? What did you argue about on the phone before he died?"

Sun Hong stammered, "I...we just have an ordinary employment relationship. The argument on the phone was because he had problems at work and I blamed him."

Wang Shuai snorted coldly: "Ordinary employment relationship? From what we know, there are financial problems in your factory. Did Li Jianshe discover anything?"

Sun Hong's forehead was covered with sweat. "No...nothing. Don't talk nonsense." Lu Chuan stared into Sun Hong's eyes and said, "Sun Hong, the evidence is very unfavorable to you now. We found clues related to you at the car theft scene and the crime scene. You'd better tell the truth, otherwise you will be severely punished by law."

Sun Hong sat in the interrogation room, his eyes evasive but pretending to be calm. Facing the questions from Lu Chuan and others, he insisted that he had nothing to do with Li Jianshe's death.

"I really didn't kill him! During the time when the incident happened, I was busy at the factory during the day and went home to rest at night. I never saw Li Jianshe at all." Sun Hong kept rubbing his hands, and fine beads of sweat oozed out of his forehead.

Lu Chuan stared at him closely, his eyes were sharp: "Sun Hong, you'd better think it over before you answer. We have a lot of evidence now. You asked Lao Wang to steal the car, and you have financial conflicts with Li Jianshe. Do you think you can get away with it?"

Sun Hong blushed and raised his voice to defend himself, "It's my own factory's business. It's a matter between my brothers and partners. The factory has been in a downturn recently, and I did some tricks in my account, but it has nothing to do with you police officers. And why has this matter nothing to do with Li Jianshe? Although he found out, this matter is our internal matter."

Wang Shuai snorted coldly, "That's easy to say. Then tell me, the person is dead, and you are talking about internal affairs?"

Sun Hong's eyes dimmed instantly, and he was silent for a while before speaking: "Yes, he did find out, but I'm already trying to find a solution. There's no need to kill him."

Zhang Hui frowned and asked seriously, "Then how do you explain your frequent quarrels with Li Jianshe and your threats against him?"

Sun Hong stood up anxiously, waving his hands: "That was just a spur of the moment statement! I was just trying to scare him because I was afraid he would tell others about it."

Then Sun Hong made a detailed report on the factory, explaining that the factory was not owned by Sun Hong, but by other partners. His partners had invested some money some time ago, but the factory had not made any progress. It was in a state of loss. In order to deal with the partners, Sun Hong falsified the accounts, which was discovered by Li Jianshe.

Lu Chuan motioned Sun Hong to sit down and continued to ask: "Then tell me in detail about the quarrel between Li Jianshe and his cousin Li Xingyao."

Sun Hong calmed down a bit and said, "About half a month ago, Li Jianshe came to the factory to see me. He was in a bad mood and kept complaining." (End of this chapter)
