The book-crossing case happened! The villains all want me to go to jail

Xie Xuan'an stood motionless at the door of Lin Hainan's bedroom, his face so gloomy that it seemed as if water could drip out of it. The solemn atmosphere pressed on everyone's heart like a lead block.

"What is going on?" Xie Xuanan broke the suffocating silence, his voice low and his eyes full of anxiety and confusion.

Zhao Hongzhi took a deep breath, as if to suppress the bloody smell in the room into his heart, and said slowly: "Don't worry, let me start from the beginning."

Time went back to a few hours ago. The seemingly peaceful appearance of the Lin family was mercilessly torn apart by a shrill scream. The servant ran over in panic, his voice becoming sharp and piercing because of extreme fear: "Oh no, something happened to the young master!"

When they rushed to the bedroom, a horrific scene came into view. Lin Hainan's young body was lying lifeless on the bed, and the bright red blood continued to spread from under his body, soaking the white sheets. He was ruthlessly pierced by a sharp blade, and the sharp tip of the knife peeked out from his back, bringing a horrifying bloody smell.

Lin Hainan's eyes were wide open, with extreme fear and disbelief in them, as if he had seen a demon from the depths of hell at the last moment of his life. His lips were slightly open, as if he wanted to shout but could no longer make a sound.

And next to the shocking bloodstain, the mysterious infinity symbol appeared again, mocking everyone in a twisted and evil posture.

The room was filled with a sickening smell of blood, and the heavy atmosphere seemed to be able to crush people. The police officers in charge of the case all had solemn faces, and every subtle expression was filled with shock and anger at this cruel case.

Some policemen carefully collected evidence by the bed, their cameras flashing constantly, recording the tragic scenes; some policemen bent over, carefully checking every trace on the ground, not missing any clues; and some policemen whispered to each other, trying to piece together possible clues to the case.

Zhao Hongzhi frowned, and the wrinkles on his forehead seemed to be engraved with deep worry. He clenched his fists, and his knuckles turned white from the force.

"The murderer obviously planned it." Xie Xuan said as he slowly walked into the room, each step seemed particularly heavy. His eyes were as sharp as an eagle, carefully observing every detail of the room.

A young policeman, Xiao Wu, came hurriedly with a folder in his hand. "Captain Zhao, we found an unsigned threatening letter in the desk drawer. The handwriting was deliberately disguised."

Zhao Hongzhi took the letter and examined it carefully. "It seems that the murderer had a plan in advance." He turned to Xie Xuan'an and explained solemnly, "Generally speaking, for this kind of threatening letter with deliberately disguised handwriting, the murderer is likely to be someone familiar with Lin Hainan, trying to cover up the characteristics of his handwriting."

Another police officer, Xiao Li, pointed at the window and said, "Captain Zhao, there are some slight scratches on the edge of this window. Someone may have tried to enter or leave through the window."

Zhao Hongzhi walked over to check, "Collect samples to see if we can extract any useful information." He looked at Xie Xuan'an again and gave him a clue, "The depth and direction of these scratches can help us determine how the suspect entered and his possible height and weight."

At this time, Xiao Wang, who was in charge of technical investigation, ran over and said, "Captain Zhao, there is a deleted call record in Lin Hainan's phone. After recovery, it was found that the number was a temporarily registered anonymous number and could not be traced."

Zhao Hongzhi frowned even more tightly, "Keep digging and see if you can find any related clues." Then he said to Xie Xuan'an, "Although this anonymous number is difficult to track directly, the signal coverage and time of the call base station can also roughly infer the suspect's location."

Under the bed, a policeman found a piece of cloth that did not belong to Lin Hainan. "Captain Zhao, look at this material. It's quite special."

Zhao Hongzhi took it and observed it. "Send it for identification first to see if the source can be found." He still insisted on explaining to Xie Xuan, "Different fabric materials and production processes often come from specific manufacturers or regions, which helps narrow the scope of the investigation."

In the pocket of Lin Hainan's coat in the closet, there was a crumpled note with an unfamiliar address written on it.

Xie Xuan'an accepted Zhao Hongzhi's explanation and looked at the note. "This address is a bit strange. Let's check where it is first."

Zhao Hongzhi nodded. "This address may be a key clue. Maybe the murderer left it there on purpose to mislead us, or maybe it was some kind of hint left by Lin Hainan himself."

There were a few inconspicuous drops of water on the carpet at the door of the room. After testing, it was found that their composition was not ordinary tap water.

Zhao Hongzhi thought and said, "This water drop may give us some direction. Let's work harder!" Then he explained to Xie Xuan, "Water from different places may contain specific minerals or chemicals. By analyzing their composition, we can infer where the suspect has been."

The policemen were busy moving around the room, each of them concentrating on not missing any possible clues.

The atmosphere in the police station's interrogation room was heavy and depressing. When Wang Ming was brought in, his face was filled with anger and arrogance, as if he was the victim.

"Why did you arrest me? This is a huge injustice!" Wang Ming yelled at the top of his lungs, slamming his hands hard on the interrogation table, causing the objects on the table to tremble slightly. His eyes were wide open, bloodshot, and seemed to be spewing fire.

The interrogating police officer Xiao Li had a serious expression and a sharp gaze. "The evidence is irrefutable. Don't even think about denying it!"

Wang Ming sneered, leaned back, and crossed his legs. "Humph, words are not enough, if you have evidence, show it!"

Xiao Li laid out the collected evidence in front of him one by one in a steady tone, "Your wife eloped with the wealthy Lin Hainan, which caused you great stimulation and became a strong motive for your crime. Look at this threatening letter. The handwriting expert has identified that its writing habits are similar to your daily handwriting in many ways. Although you have carefully disguised yourself, you cannot escape professional analysis. Also, the piece of cloth found at the crime scene is made of exactly the same material as the suit you recently ordered."

Wang Ming's face turned pale instantly, and a hint of barely perceptible panic flashed in his eyes, but he quickly pretended to be calm and shouted, "This is just a coincidence! Don't try to use this to accuse me!"

At this moment, behind the two-way mirror in the interrogation room, Xie Xuanan stood quietly. His bangs drooped, covering part of his eyes. Under the shadow, his eyes were deep and sharp, revealing a calmness and concentration that others could hardly detect.

Xie Xuan'an analyzed in his mind: From the perspective of criminal psychology, Wang Ming's excessive anger and strong denial are often manifestations of inner fear and guilt. His body language, such as frequent shaking of legs and clenched fists, all show his nervousness and anxiety. According to the theory of emotional response, when people are extremely nervous and try to cover up the truth, they will have physiological stress reactions, such as sweating and accelerated heartbeat, and the fine beads of sweat on Wang Ming's forehead just verified this.

However, behind these seemingly clear cases, the mysterious infinity symbol was like a fog, lingering in Xie Xuan'an's mind. The infinity symbols that appeared in the two cases were definitely not drawn by the murderer, which made him feel deeply puzzled.
