The crackdown on organized crime began with the arrest of the mother-in-law.

Chapter 928 Breakthrough in Investigation, Obtained Without Any Effort

As they left the villa area, Xiao Zhang glanced at the hillside villas in the rearview mirror: "Captain Li, Chen Guisheng's wife was wearing a red dress and pearl earrings. Her figure is similar to the woman in the red dress in the surveillance footage, and her watch..."

“I noticed,” Li Ming frowned, “but Chen Guisheng has a complete alibi, and it’s unlikely that Lin Wanqing, as a sickly wife, would commit the crime alone.” He suddenly remembered something, “Investigate Chen Guisheng’s financial flows, especially the 20 yuan ‘tea money,’ and see if it was transferred to Chang Baofeng’s brother’s account.”

At 3 p.m., the technical department reported: "After the 200,000 yuan 'tea money' was deposited, Guo Jianfeng immediately transferred the money to an overseas account. The account holder's name is 'LIN WAN QING,' which is the same as Chen Guisheng's wife's English name."

Li Ming suddenly stood up: "Notify the Economic Crime Investigation Team to freeze all of Lin Wanqing's accounts. Also, re-examine Guo Jianfeng's phone and check his communication records with Lin Wanqing—Chen Guisheng's nickname 'Old Ghost' may have been used by someone."

At six o'clock in the evening, Li Ming came to the villa again. This time, Lin Wanqing opened the door. She had changed into a plain cheongsam, and her pearl earrings gleamed coldly in the sunset. "Captain Li," she said with a smile as she made tea, "I forgot to mention last time that Guo Jianfeng once helped me handle a jewelry investment. It lost some money, and when my husband got angry, I even spoke up for him."

"Really?" Li Ming stared at her earring. "Was that investment made using your overseas account?"

Lin Wanqing paused, the teaspoon falling into the teacup: "Captain Li, what do you mean by this?"

“What I mean is,” Li Ming showed the transfer record, “that after Guo Jianfeng received 20 yuan from Mr. Chen, he immediately transferred it to you. And you might be the one who used the name 'Old Ghost' to threaten him.”

Lin Wanqing's face turned deathly pale instantly, and her shoulders trembled slightly beneath her cheongsam: "I don't understand what you're saying..."

“You understand,” Li Ming pressed closer, “you used your husband’s nickname to intimidate Guo Jianfeng, forcing him to transfer money to your overseas account, and even went so far as to kill him to cover it up. The ‘big project’ that Guo Jianfeng mentioned before he died didn’t exist at all; it was just a front for your money laundering!”

At this moment, Chen Guisheng suddenly rushed down from the second floor: "You're talking nonsense! How could my wife kill someone! She wouldn't even dare to kill a chicken!"

“But she dared to have someone inject Guo Jianfeng with a sedative,” Li Ming pulled up the pharmacy’s surveillance footage. “On March 11, your driver bought diazepam at the pharmacy, and he went to Jinshi Financial that day—” He turned to Lin Wanqing, “You instructed your driver to do it, didn’t you? First, make Guo Jianfeng incapacitated, then have someone strangle him, deliberately leaving behind clues like a red dress and earrings, trying to frame Chang Baofeng.”

Lin Wanqing finally broke down, collapsing to the ground: "It was...it was me who made Ah Zhong do it...Guo Jianfeng knew too much, he said he was going to report us..." She raised her head, her eyes filled with madness, "I can't let him ruin our lives! That money is all shady!"

Chen Guisheng looked at his wife in shock: "Wanqing, you..."

"Shut up!" Lin Wanqing screamed. "You think your coal mine money is clean? If I hadn't helped you launder the money, you would have been investigated long ago! Guo Jianfeng, that idiot, actually thought he could help me earn my dowry through financial management—" She suddenly realized she had let something slip and covered her mouth in horror.

Looking at the couple, Li Ming understood: "Chang Baofeng is your sister, right? You deliberately misled the police with the red dress and earrings, making us think she was the murderer, but we didn't expect that she actually entrusted Guo Jianfeng with her finances, which cleared her of suspicion." He turned to Xiao Zhang, "Take her back to the station and start the interrogation immediately."

As night fell, the lights in the villa on the hillside went out one by one. Li Ming stood at the door, watching the police car drive away, recalling Lin Wanqing's last words—"dowry." It turned out that Chang Baofeng's "making big money" was actually helping her sister launder money, and Guo Jianfeng was just a pawn on their chessboard, paying the price for their greed with his life.

Xiao Zhang handed over the case report: "Captain Li, the composition of Lin Wanqing's nail polish matches the skin tissue under the deceased's fingernails. She is the one who scratched Guo Jianfeng."

At 11 p.m., under the cold lights of the interrogation room at the Dongchuan City Criminal Investigation Detachment, Lin Wanqing sat on an iron chair, her cheongsam collar slightly open, revealing her delicate collarbone. Her fingers, painted with pearl-colored nail polish, tapped lightly on the table, her eyes radiating arrogance, as if the interrogation before her was merely an insignificant afternoon tea party. Li Ming sat opposite her, clutching a DNA comparison report, his knuckles white from the pressure.

“Lin Wanqing, tell me,” Li Ming pushed the report in front of her, “The skin tissue under Guo Jianfeng’s fingernails matches your DNA perfectly.”

Lin Wanqing raised an eyebrow, a cold smile playing on her lips: "Captain Li, my husband's driver carries my bags and drives me around every day. He comes into contact with countless people. What does that prove?"

“But the scratches were formed before he died,” Li Ming pulled up the forensic photos. “The scratches on Guo Jianfeng’s right cheek have your nail polish residue on the edge of the wound. The pearl powder on your nails is consistent with the trace substances in his wound.”

Lin Wanqing's smile froze, and her fingertips stopped tapping. She looked down at her nails, as if confirming something. Li Ming pressed on: "On March 11th, your driver, Ah Zhong, bought diazepam at the pharmacy. The surveillance footage showed him wearing a mask, but his build and gait matched perfectly."

“My husband has insomnia,” Lin Wanqing quickly regained her composure. “It’s normal for a driver to buy medicine.”

"Then why does the diazepam in Guo Jianfeng's body have the same batch number as the one in your medicine cabinet?" Li Ming showed the pharmacy's delivery slip. "This batch of medicine was supposed to be ten boxes, but you only have eight boxes left in your safe. Where did the other two boxes go?"

Lin Wanqing's expression finally changed. She licked her dry lips and remained silent. Li Ming knew the time was right and softened his tone: "We investigated Chang Baofeng. She's your biological sister, right? You were adopted when you were young. She took her adoptive father's surname, Chang, while you took your adoptive mother's surname, Lin. Last year, you had her get close to Guo Jianfeng to use him for money laundering, didn't you?"

These words struck Lin Wanqing like a hammer blow to her vitals. She looked up abruptly: "How did you know...?"

“Your sister’s bank statements show that the overseas funds she received were ultimately transferred to your account,” Li Ming showed the flow of funds. “Guo Jianfeng thought he was helping her manage her finances, but he was actually helping you launder money. It wasn’t until he discovered the source of the funds was problematic and threatened to report it that you decided to kill him.”

Lin Wanqing suddenly burst into laughter, her body trembling with mirth: "Report him? He's been corrupt for a long time! He took 20 yuan from me as 'tea money' and helped me disguise my dirty money as financial investments. Now he wants to walk away? No way!"

“So you had Ah Zhong put diazepam in his coffee,” Li Ming continued. “On the day of the incident, at noon, you wore the red dress Chang Baofeng gave you, sunglasses, and took the freight elevator to the rooftop. Guo Jianfeng drank the drugged coffee and became disoriented. You took the opportunity to have Ah Zhong inject him with an overdose of sedatives, and then strangled him with a wire you had prepared beforehand.”
