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

Zhang Kai responded over the phone: "Yes! During the autopsy, a slight subcutaneous hematoma was found on the back of the deceased's head. At the time, it was speculated that it might have been caused by a fall, but the specific object that caused the fall could not be found. Now, combined with Sun Zhengjun's identification and the stones at the scene, it completely matches up, which further confirms the authenticity of his confession. Moreover, the gray fibers around the deceased's mouth and nose are consistent with the fibers of the coat, and the method of suffocation is also consistent with the characteristic of 'covering the mouth and nose with a soft object'."

Sun Zhengjun also confessed that after disposing of the body, he returned to his parking spot and threw a pair of gloves, which had a small amount of dust and fibers on them, into a corner of the third-floor corridor of Building 2 before driving away. Yang Lin immediately led a team to the third-floor corridor of Building 2, where they indeed found a pair of worn-out gloves in the corner pointed out by Sun Zhengjun. The gloves had gray cotton fibers and a small amount of soil on them. Tests showed that the fibers matched the deceased's coat, and the soil composition also matched the soil at the site of the unfinished building.

The entire identification process lasted for more than two hours. Sun Zhengjun gave a detailed confession of every detail of the murder and body disposal. All the details corresponded precisely with the key information found at the scene, such as tire tracks, drag marks, fiber residue, glove evidence, and the cause of death and head impact marks determined by the autopsy, forming a complete chain of evidence.

After the identification process, Sun Zhengjun was escorted away from the unfinished building. His head remained bowed low, all traces of his previous excuses and wishful thinking gone, replaced only by remorse for his crimes and fear of legal punishment. Watching Sun Zhengjun's retreating figure, Wang Shuai said to Yang Lin, "All the details match up; the chain of evidence is complete. This case can now be definitively closed."

Yang Lin nodded, a hint of relief in his voice: "From the on-site investigation and autopsy to confirming the identity of the deceased, tracking down the suspect, and now to the on-site identification, every step is closely linked, finally giving the deceased and his family an explanation."

That afternoon, the police compiled and summarized the on-site identification records, previous interrogation records, investigation reports, autopsy reports, and other materials to further improve the case file. All the evidence in the Tian Zheng murder case has been secured, with clear logic and complete details, providing a solid basis for subsequent judicial trials.

At the Chengdong vegetable market, Tian Zheng's pork stall was already empty. Nearby vendors, upon hearing the news of the case's resolution, were filled with emotion. When Tian Zheng's wife, Liu Mei, received notification from the police that the details of the crime scene identification perfectly matched the evidence, and that the murderer's crimes had been completely exposed, she finally broke down in tears, both grieving for her husband's passing and finding solace in the arrival of justice.

With the completion of the on-site identification, the Tian Zheng murder case has officially entered the next stage of the judicial process. Sun Zhengjun will face severe legal sanctions for intentional homicide. He has paid a heavy price for his momentary impulse and侥幸心理 (a sense of侥幸, or a belief that he could get away with it). This price will also serve as a warning to many others—any behavior that crosses the line of the law will ultimately be severely punished. Justice may be delayed, but it will never be absent.

Less than a week after Tian Zheng's case was solved, the Criminal Investigation Detachment received another report that a body had been found at the Dongshan Coal Mine.

On Wednesday afternoon at 2 p.m., the mountains surrounding Dongshan Coal Mine were shrouded in a gray fog. The barbed wire at the entrance to the abandoned mine was rusty, and the "No Entry" sign had long since faded, leaving only blurred lettering. Security guard Zhou Mingqiang walked along the patrol route around the mine with a flashlight in hand—his daily routine—checking for scavengers or explorers who might have trespassed.

As he reached the entrance to the main mine shaft, the beam of his flashlight inadvertently swept across the interior, and he suddenly caught a glimpse of a human-shaped silhouette huddled in the darkness, the color of its clothing standing out starkly in the dim light. "Who's in there?" Zhou Mingqiang called out, but received no response. He mustered his courage and took two steps forward. As the beam drew closer, a motionless corpse came into view, its limbs twisted, its body covered in dirt and mineral dust, a faint, unpleasant odor wafting from the mine shaft.

Zhou Mingqiang shuddered in fright, nearly dropping his flashlight. He turned and ran down the mountain, pulling out his phone as he ran: "Hello! 110? A dead body has been found in an abandoned mine shaft at Dongshan Coal Mine! Help!"

The urgent sirens shattered the silence of the mountain forest. Forty minutes later, Lu Chuan's police car stopped in an open area at the foot of the mine. "Seal off the scene immediately!" Lu Chuan opened the car door, his dark gray police uniform covered in dust. He pointed to the mine entrance and a 30-meter radius around it, and gave instructions to his team: "Use warning tape to cordon off the entire area, prohibiting any unauthorized personnel from approaching. Contact the mine manager and dispatch personnel to assist in guarding all entrances to prevent anyone from tampering with the scene or escaping. Yang Lin and Yang Sen, you take all the investigation tools and come with me into the mine to investigate. The terrain inside the mine is complex and the lighting is dim, so watch your step. Focus on checking the location of the body, the surrounding environment, and whether there are any remaining traces. Wang Shuai, you stay outside and question the person who reported the case, Zhou Mingqiang, in detail to find out the specific process of discovering the body, the recent activities of people around the mine, and whether there are any unusual signs."

Yang Lin and Yang Sen quickly shouldered their exploration bags, put on headlamps and gloves, and followed Lu Chuan into the mine. The moment they stepped inside, a wave of damp, cold air, mixed with coal dust and a musty smell, hit them. The ground beneath their feet was uneven, covered with gravel and abandoned mine slag. The beams of their headlamps could only illuminate a few meters ahead in the darkness. The mine shaft was about three meters high, with black coal stains covering the rock walls on both sides. In some areas, there were signs of water seepage, and water droplets dripped down the rock walls, making a clear "drip-drip" sound in the silent mine.

The body was curled up about 50 meters deep in the mine, near an abandoned minecart track, surrounded by several loose rocks and broken planks. "Observe the overall environment first, and don't touch the body unnecessarily." Lu Chuan gestured for the two to stop, focusing the beam of his headlamp on the area around the body. "Look, the slag and gravel around the body show signs of being moved. Was it deliberately covered up after the crime? And these planks are arranged rather neatly, not like they were scattered naturally."

Yang Lin nodded, turned on the high-intensity survey light, and swept the beam across the body: "The deceased is male, about 170 centimeters tall, of medium build, wearing dark blue overalls with multiple tears and covered in a lot of mineral dust and dirt, making it impossible to see the specific style; the body is lying on its side in a curled-up position, with its head against the rock wall, its hair messy and covered in coal dust, making it impossible to determine its age and facial features at the moment."

Yang Sen then focused his examination on the ground surrounding the body: "There are a few blurry footprints on the ground, but the dust inside the mine is too thick, and most of the footprints are already indistinct. Only the approximate shoe size can be discerned, around size 43." (End of Chapter)
