Chapter 823 DNA Identification and Analysis, Repair Shop
After leaving the construction site, Li Ming led his team to two other construction sites, but after some investigation, they did not obtain any more valuable clues.
Meanwhile, Qin Chuan returned to Hongxing Village. He decided to start by investigating Wang Jianjun's relationship with the villagers, hoping to find a new breakthrough. He and his criminal investigation team visited each household, asking the villagers about Wang Jianjun. In a corner of the village, they encountered an elderly man sunbathing in his yard.
"Sir, are you acquainted with Wang Jianjun's family?" Qin Chuan stepped forward and asked politely.
The old man raised his head, looked at Qin Chuan, and slowly said, "I know them well. This family has lived in the village for many years. But after Wang Jianjun moved away six months ago, he seems like a completely different person when he came back."
"How exactly will the changes be implemented?" Qin Chuan asked, intrigued.
“He used to have a bad temper, but he was still fairly decent. This time when he came back, he was acting all mysterious and associating with some shady people. Once I saw him arguing with some young men at the village entrance. Those young men didn’t look like good people, and they even threatened him.” The old man recalled, a worried look on his face.
"Sir, do you know who those young men are?"
The old man shook his head. "I don't know. They're all unfamiliar faces, and they look like gangsters. I also heard that after Wang Jianjun came back, he seems to have owed a lot of money to others and is being chased by debt collectors."
After leaving the old man, Qin Chuan fell into deep thought. Wang Jianjun's debt problem might be intricately linked to the case. He decided to go to the village credit union to find out about Wang Jianjun's financial situation. At the credit union, the person in charge checked the records and told Qin Chuan that Wang Jianjun had indeed taken out a loan six months ago, but the repayment deadline had passed and he had not yet made the payment.
"Then what is he going to do with the loan?" Qin Chuan asked.
"They say they want to expand their business, but we're not really sure what kind of business they'll be doing," the person in charge replied.
After leaving the credit union, Qin Chuan received a call from Li Ming.
Li Ming reported on his investigation in the southern suburban industrial park over the phone. Aside from the limping man loitering outside the construction site, there were no other significant discoveries. Qin Chuan told Li Ming about what he had learned in the village regarding Wang Jianjun's debts and interactions with strangers. After discussing it, the two decided to continue investigating clues related to the limping man while also delving deeper into Wang Jianjun's debt relationships to see if they could find the creditors and the strangers who had contact with him.
Back at the police station, Qin Chuan and Li Ming interrogated Wang Yutong again. In the interrogation room, Wang Yutong remained tense, her eyes darting around.
“Wang Yutong, we have already gathered a lot of information about your father’s debts and his dealings with those strangers. You couldn’t possibly be completely unaware of this.” Qin Chuan stared intently at Wang Yutong, trying to catch a clue in her expression.
Wang Yutong bit her lip. "I really don't know. My dad never talks to me about these things. I only know that he seems to be in trouble, but I really don't know what exactly."
"So what exactly happened to the injury on your wrist? Last time you said you hurt yourself by accident, but our investigation found that it looks more like a scratch." Li Ming suddenly asked.
Wang Yutong instinctively covered her wrist, a hint of panic flashing in her eyes. "I... I really did it by accident, it really has nothing to do with the case."
The interrogation lasted for several hours, but Wang Yutong remained tight-lipped. Qin Chuan and Li Ming reluctantly ended the interrogation, but they knew that Wang Yutong must know some crucial information, but was afraid to reveal it for some reason.
Just when the case seemed to have reached a stalemate, the technicians brought good news. After in-depth analysis of the buttons retrieved from the scene, they extracted residual DNA, but unfortunately, no match was found. The database is still searching for the suspect.
However, the presence of a unique oily component detected by technicians in the button scratches brought new hope to the case. Qin Chuan immediately decided to shift the focus of the investigation to the oily clues.
Through in-depth analysis, technicians determined that this special industrial lubricant was primarily used in specific types of machinery. Using a professional database, they meticulously screened the supply chain and ultimately identified a lubricant supplier located in the suburbs—Hongtai Chemical. Qin Chuan immediately dispatched criminal investigation team members to Hongtai Chemical for further investigation.
When the investigators arrived at Hongtai Chemical, the person in charge was initially a little nervous, but gradually relaxed after showing his credentials and explaining the purpose of their visit. "Our lubricant sales are pretty good; we have quite a few customers, mainly factories and repair shops," the person in charge said.
"Has anyone recently made large purchases of this special type of lubricant? Or are there any particularly special customers?" the team member asked.
The person in charge looked through the sales records, pondered for a moment, and said, "About a month ago, a man named Li San came to purchase a batch of goods, more than usual than other customers. However, he said he was purchasing for a repair shop, but I don't know which one."
They meticulously recorded Li San's information and conducted a thorough investigation of Hongtai Chemical's inventory management and sales channels to ensure no clues were overlooked. After leaving Hongtai Chemical, the criminal investigation team began tracking Li San using the contact information he had left behind. After making inquiries from various sources, they finally located Li San.
When questioned by the criminal investigation team, Li San initially tried to hide the truth, but under intense psychological pressure, he finally confessed: "I was just running errands for someone. A repair shop called Wantong in the southern suburbs asked me to buy it. They offered me a little more money than the market price, so I took the job."
Upon receiving this news, Li Ming immediately led his team to Wantong Repair Shop. Inside, the machines were noisy, oil stains were everywhere, and workers were busy repairing various mechanical equipment. Qin Chuan found the factory manager, identified himself, and asked, "Your factory had Li San purchase a batch of special lubricating oil a month ago. Which equipment has this oil been used on?"
The factory manager looked bewildered. "I don't know much about this. Our procurement is usually handled by the logistics department." He quickly called over the logistics supervisor.
The logistics supervisor recalled, "Oh, yes, that's right. A guy named Zhao Kaifeng brought over a piece of equipment, saying it needed deep maintenance and he specifically requested a special lubricant. He offered a considerable amount of money, so we purchased it according to his requirements."
"Zhao Kaifeng?" Li Ming's heart tightened. This name had appeared in the investigation before, and he didn't expect to be associated with it again.
"What does this Zhao Kaifeng look like? Has he ever been to the factory before?" Qin Chuan asked eagerly.
The logistics supervisor described Zhao Kaifeng's physical characteristics, which matched the information previously gathered. "He came back once more later, took the equipment, and then never came back," the logistics supervisor added.
Li Ming wanted to report to Qin Chuan.
