Wrong Interrogation Room, The First Cracked Case Shocked the World

Chapter 6: Pressing step by step, stunning everyone!

"Zhang Dongyang, what else do you want to say?" Ning Cheng leaned back in his chair, a cruel smile playing on his lips. His unwavering gaze pierced Zhang Dongyang, sending a shiver down his spine and raising goosebumps on his skin.

"I didn't commit a crime, I didn't kill my wife!" Zhang Dongyang turned his head slightly, fighting back the fear that threatened to consume him. "I don't know what the luminol reaction is, and I don't know how to resolve it!"

"Whether you know it or not, you murdered her. Brutally murdered her," Ning Cheng said calmly. "Even if you deny it, the evidence I've presented casts a dark shadow of suspicion over you."

Zhang Dongyang's teeth clenched in frustration. Ning Cheng was right. If there were substances that could neutralize the forensic luminol reagent, his alibi would crumble.

"I repeat, I didn't kill my wife, Li Meier!" Zhang Dongyang insisted. "The police are pumping water in the sewers, and the forensic doctor with the police dog couldn't find my wife's DNA. And the police dog found my wife's silk scarf in the square at the entrance of our community. How do you explain that? If she wasn't running away with her lover at five in the morning, why would she leave her scarf in such a hurry?"

"Because the silk scarf was planted there by you, Zhang Dongyang!" Ning Cheng's reply made Zhang Dongyang's eyes narrow.

Ning Cheng shook his head, his confidence unwavering. "Compared to me, your killing experience is still immature. You placed the silk scarf at the community gate to deliberately create the illusion that your wife is not dead and is walking out with her lover. At the same time, the police found no blood traces in your house, and no DNA evidence of your wife in the sewers. These findings, verified by the police, actually support the narrative that your wife and her lover ran away. But it's all too coincidental, too carefully orchestrated!" Ning Cheng's smile held a hint of mockery.

"Why deliberately? I don't understand," Zhang Dongyang muttered, unconsciously reaching for the burning cigarette on the table.

"The community has cameras. Since there are no images of your wife around your house, and the only image of her is in the community square, it suggests a blind spot in surveillance. You took advantage of that blind spot to place your wife's silk scarf in the community square, to mislead the police!" Ning Cheng's voice was low and steady.

Outside the interrogation room, the criminal police gathered around the monitor, their eyes wide with shock. Ning Cheng's deductions were spot on. Zhang Dongyang's community was located in the old city, riddled with surveillance blind spots, making it easy for him to manipulate the evidence.

Zhang Dongyang took a deep breath, trying to control his trembling hand. "I didn't put the scarf on the square. My wife ran away with her lover. She betrayed me."

"Don't try to deceive me," Ning Cheng scoffed, raising his portfolio. "Your interrogation record is in this file. You said that your wife woke up at 5:30 in the morning, found you gone, and that nothing was missing from the house when she left."

"Yes," Zhang Dongyang replied, his voice unwavering.

"That's a lie!" Ning Cheng's lips curled into a sinister smile. "A woman running away with her lover wouldn't leave behind anything? Not even a single piece of clothing? A toothbrush? A change of clothes?"

"The information in this file shows that you and your wife, Li Meier, were an old husband and a young wife. She's only 29 years old, still at the height of her beauty. And the community cameras didn't capture any images of her and her lover?"

"I didn't kill my wife, Li Meier. If you insist on saying I did, then why can't the police find her body in the sewers?" Zhang Dongyang suddenly stood up, his eyes blazing with anger.

"Don't try to hide your guilt behind your loud voice, it only reveals your desperation," Ning Cheng retorted. "As for your question, it's a good one. Why couldn't the police dogs and forensic doctors find her body in the sewers? Because there is no body in the sewers. Murder and dismemberment, it's impossible to transport the body away without being seen, and it's impossible to flush it down the toilet sewer without the police noticing. There's only one way to dispose of the body without it being discovered."
