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

Li Yong stiffened his neck, his face full of stubbornness: "I have no idea what you are talking about! Wang Xuebing and I have no grudges against each other, why do you want to kill him?"

Wang Shuai pushed the footprint photo in front of him: "This is a size 43 shoe print extracted from the crime scene. It is exactly the same as the pattern of the pair of sneakers in your home. How do you explain it?"

"Anyone can wear my shoes! Does this prove that I killed that person?" Li Yong widened his eyes and retorted with forced calmness.

Lu Chuan took out the fingerprint comparison report again: "Your fingerprints were extracted from multiple places at the scene, including the door lock of the fire escape and the drawer of Wang Xuebing's study."

"I used to work in property management, so it's normal for me to have been to that building!" Li Yong's voice began to tremble, but he was still quibbling.

When Zhang Hui took out the DNA test report, Li Yong finally panicked. The report clearly showed that the DNA of the skin tissue extracted from Wang Xuebing's fingernails was a perfect match with his.

"This is impossible! You must have made a mistake!" Li Yong shook his body frantically, and the metal handcuffs hit the chair handles with a harsh sound.

Lu Chuan slammed the table so hard that the water cup on the table jumped up. "Li Yong, don't be stubborn! From the time you took customer orders privately and were fired by Wang Xuebing, to the time you deliberately changed your duty hours and destroyed the surveillance in advance, to the time you used a wrench to pry open the door of the fire escape, we have investigated everything clearly!"

Li Yong's face turned pale, and beads of sweat rolled down his forehead. He was silent for a long time, and finally lowered his head, muttering to himself: "I didn't want to kill him. I really didn't want to kill him."

Under Lu Chuan's constant questioning, Li Yong finally began to confess the crime. It turned out that he had been holding a grudge since he was fired, and when he learned that Wang Xuebing was often alone at home, he began to plan revenge. He had figured out the surveillance layout of the community in advance, and took advantage of his convenience in working in the property management to switch the duty on the night of the crime.

"That night, I went upstairs from the fire escape." Li Yong's voice was hollow and hoarse. "I just wanted to scare him and make him return the money he had taken from me. But when he saw me, he shouted for help and picked up the ashtray on the table and threw it at me. I got so excited at the time that I..." He couldn't go on and just kept shaking.

When asked about the weapon used to commit the crime, Li Yong gritted his teeth and said, "I buried the knife under the old tree in the small garden of our community."

At daybreak, the police immediately rushed to the location Li Yong mentioned. In the small garden, an old man was doing Tai Chi in the morning, completely unaware that key evidence of a murder case was about to be uncovered here. Lu Chuan directed the police officers to carefully dig up the soil under the old tree, and soon a black plastic bag was revealed.

After opening the plastic bag, a gleaming dagger appeared in front of everyone, with dark red bloodstains on the blade. After inspection, it was found that the bloodstains were from Wang Xuebing, thus completing the chain of evidence for the entire case.

In the following three days, the police integrated the entire chain of evidence, collected all the evidence, and combined it with Li Yong's confession. Relatively speaking, the entire case can be said to be completely closed. The next important step is to escort Li Yong to the crime scene for identification.

The tenth day after the incident.

As the morning light pierced through the clouds, the police car that escorted Li Yong slowly drove into the Golden Sun Community. He curled up in the back seat, his handcuffed hands tightly grasping the corners of his prison uniform, his nails almost digging into his palms. The residents gathered outside the cordon whispered to each other, and the constant discussions were like invisible whips whipping him.

"Get out of the car." Lu Chuan opened the door of the police car. The morning breeze blew in the fragrance of magnolia flowers, but it couldn't dispel the strong smell of sweat on Li Yong's body. His knees seemed to be nailed down, and it was not until the special police gently pushed him from behind that he staggered onto the familiar concrete floor. He had patrolled the cobblestone road countless times as a security guard, but now every step he took hurt his feet.

Turning the corner of Building 11, the outline of Building 12 came into view. Li Yong suddenly trembled violently, and a vague whimper came out of his throat. The scene of being publicly humiliated by Wang Xuebing three months ago exploded in front of his eyes - that day the boss threw the contract in his face, and spit splashed on the collar of his newly bought shirt: "How dare you betray me? I can make you have no chance in the entire building materials industry!"

"Where did you enter the community?" Lu Chuan's voice interrupted the recollection. Li Yong turned his head mechanically and pointed to the side door of the underground garage: "Here. I figured out the blind spots of surveillance two weeks in advance." His eyes fell on the rusty door lock. When he pried it open with a wrench late that night, the crisp sound of broken metal seemed to still echo in his ears.

Going down to the garage, the damp musty smell mixed with the smell of engine oil hit me in the face. Li Yong stopped in front of the fire escape door, his Adam's apple rolling up and down: "I'll change the duty roster to my own, and hide here at 9:20." He gestured at the height, "When you hear Wang Xuebing's footsteps coming down the stairs, use the spare key to open the door." Several traces of nervous scratching can be vaguely seen on the wall.

Going up the fire escape stairs, Li Yong's breathing became more and more rapid with each step. At the corner of the second floor, he suddenly pointed to the wall and said, "I adjusted my breathing here and put on my hat and mask." The scene of that day came to him uncontrollably - he held the folding knife in his pocket, listened to his heartbeat like a drum, and dug his nails deep into his palm to stay calm.

In front of Room 201, the cordon swayed gently in the morning breeze. Li Yong stared at the door handle, his pupils suddenly contracted: "He was still looking at his phone when he opened the door, he was not prepared at all." His voice suddenly rose, "I just wanted to scare him! But he shouted for help when he saw the knife, and even grabbed an ashtray and hit me!" In his memory, Wang Xuebing's flushed face and the splattering blood overlapped, and he subconsciously raised his hand to cover his eyes.

The moment he pushed open the door, the smell of disinfectant stung his nose. Li Yong stood stiffly at the entrance, his eyes sweeping over the once familiar layout. The dents on the sofa seemed to still retain Wang Xuebing's body temperature, and the whiskey glass on the coffee table was covered with dust, forming a strange echo with the amber-colored liquid that night.

"How did he commit the crime?" Lu Chuan's voice pierced the stagnant air like an ice cone. Li Yong staggered to the center of the living room, and the tiles under his feet suddenly became hot: "He retreated to the coffee table and knocked over the wine bottle. I grabbed his wrist and stabbed him uncontrollably with the knife." His fingers twitched like a spasm, as if he was still holding the knife. "The first stab missed, and he struggled too hard, so I stabbed him several more times."

The corner of the TV cabinet that was highlighted during the bloodstain identification turned into scarlet in Li Yong's eyes. He remembered that Wang Xuebing finally fell there, his fingers scratching the ground in vain, leaving three bloodstains on the wooden floor. At that time, he was panting, staring at the blood dripping from the blade, with only one thought in his mind: It's over, completely over. (End of this chapter)
