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

Chapter 1506 On-site investigation completed, clues provided.

Standing before Li Ming, Xiao Yang said solemnly, "Team Leader Li, the on-site investigation is complete. Following the principle of 'from far to near, and from near to far,' a comprehensive and meticulous investigation was conducted. A second review was also carried out, and no detail was overlooked. Here is a brief report on the on-site investigation:"

"First, the on-site environment. The crime scene was located in a ditch between the sidewalk and the non-motorized vehicle lane on the north side of the eastern section of Jianshe Road. The ditch was about 50 centimeters wide and 40 centimeters deep, with 10 to 15 centimeters of silt and sewage inside. Fallen leaves, plastic bags, and other household garbage were floating on the surface. The surrounding area consisted of old residential buildings, small shops, and a non-motorized vehicle lane. There was an intersection 50 meters to the east and a convenience store 30 meters to the west. There were two surveillance cameras within 100 meters of the scene, but the surveillance equipment at the intersection was old, the image was blurry, and the angle was incorrect. The angle of the surveillance camera at the entrance of the convenience store was also incorrect, and neither could capture the crime scene. No surveillance footage related to the case was obtained. No obvious signs of a struggle, bloodstains, or other suspicious traces were found around the scene. There were only a small amount of fallen leaves, household garbage, and silt on the ground, which was consistent with the usual environment."

"Secondly, the surface examination of the body. The deceased was male, preliminarily estimated to be between 35 and 45 years old, about 172 cm tall, of medium build, with short hair. His face was swollen and contorted, with slight signs of decomposition. His lips were purple, his conjunctiva was congested, and his nasal cavity and mouth were filled with mud and sewage. The deceased was wearing a dark coat, light-colored underwear, dark trousers, and dark socks. All the clothes were soaked in sewage and covered with mud and stains. There were slight tears in the cuffs of the coat and the hems of the trousers. There was a light brown stain on the back of the coat. No obvious external injuries were found on the head, neck, chest, waist, buttocks, and legs. Only on the left side of the abdomen, near the lower part of the ribs, there was a narrow, long, single-edged stab wound. The wound was about 5 cm long and 1 cm wide, with neat and smooth edges. There was slight swelling, bruising, and a small amount of coagulated blood around the wound. The preliminary judgment is that the direct cause of death was stab wound to the abdomen, resulting in excessive blood loss."

"In addition, the victim's pockets were thoroughly searched, and all four pockets were empty. No items that could identify the victim, such as an ID card, mobile phone, wallet, bank card, etc., were found, nor were any other suspicious items found. Hair and fiber traces were extracted from the victim's hair, between the fingers, and from the silt and ditch railings around the body. The fibers and hair between the victim's fingers were most likely left by the victim scratching the murderer or surrounding objects during the struggle."

"Secondly, regarding the collection of trace evidence. During this on-site investigation, a total of 15 pieces of trace evidence were collected, including: 3 black hairs (from the ditch railing, the silt around the body, and the deceased's hair), 5 light-colored fibers (from the deceased's hair and between the fingers), 2 silt samples (from the sidewalk tiles and the area around the body), 1 sewage sample (from the area around the body), 1 suspected bloodstain sample (from the deceased's underwear abdomen), 1 stain sample (from the deceased's coat back), and 2 clothing fiber samples (from the deceased's coat cuffs and trouser hems). All trace evidence has been marked and properly stored, and has been sent to the laboratory for priority testing. The focus of the testing is on whether the suspected bloodstain sample is indeed blood, whether the hair is human hair and its DNA information, and the material and origin of the fibers. Further analysis of case leads will be conducted based on the test results."

"Finally, the on-site investigation conclusions: After a comprehensive and meticulous on-site investigation, combined with analysis of the body's surface, it has been preliminarily confirmed that the deceased was male, between 35 and 45 years old, and the cause of death was a stab wound to the abdomen, resulting in excessive blood loss. The fatal wound was a single-edged sharp weapon stabbed into the left side of the abdomen, and the weapon is preliminarily identified as a single-edged dagger. The perpetrator demonstrated strong counter-investigation awareness, taking all items from the deceased's body that could identify him after the crime, cleaning up traces and evidence at the scene, and the surrounding surveillance cameras did not capture the crime scene, nor were any witnesses found. This on-site investigation has not confirmed the specific identity of the deceased, nor has it uncovered any significant clues to identify the suspect. Further investigation and screening will be expanded based on laboratory test results to find more clues related to the case, confirm the deceased's identity, and identify the suspect."

After Xiao Yang finished his report, he lowered his head and awaited Li Ming's instructions. Li Ming, after listening to the report, remained serious, tapping his fingers lightly on the table as he fell into deep thought. After a moment, he looked up at Xiao Yang and said in a stern tone, "Good, Xiao Yang, your on-site investigation was very meticulous and thorough. You didn't miss any details, and the trace evidence you collected was quite comprehensive. Thank you for your hard work."

He paused, then continued, "Currently, the case faces two key challenges: first, the identity of the deceased cannot be confirmed; second, there are no significant leads to identify the suspect. To address these challenges, I've arranged the following follow-up work: First, the technical team should closely monitor the laboratory's testing progress. Once the results are available, report to me immediately, focusing on the test results of suspected snow samples, hair, and fiber samples, striving to find information about the deceased's identity or clues to the suspect from these traces and physical evidence; second, the investigation team should expand the scope of the investigation. On one hand, thoroughly investigate all shops and residential buildings around Jianshe Road, searching for witnesses and inquiring whether any suspicious persons, vehicles, or unusual circumstances have been observed recently; on the other hand..." First, investigate recent missing persons in the city, comparing the deceased's age, height, build, clothing characteristics, and possible hidden features such as dental work or tattoos to determine the victim's identity as quickly as possible. Second, conduct a comprehensive search of surveillance cameras around the scene, extending beyond a 100-meter radius to a 500-meter range to see if any footage captures the vicinity of the crime scene, the suspect's movements, or the vehicle used in the crime. Third, have a forensic pathologist conduct a full autopsy as soon as possible to further confirm the cause and time of death, as well as the specific characteristics of the murder weapon. Simultaneously, extract the victim's DNA sample and input it into the national DNA database for comparison to assist in confirming the victim's identity.

"Understood, Captain Li!" Xiao Yang said solemnly. "Our technical team will closely monitor the progress of the laboratory testing. We will report to you immediately if we make any discoveries. At the same time, we will cooperate with the investigation team to carry out follow-up investigations, do our best to assist in solving the case, identify the deceased as soon as possible, identify the suspect, and bring justice to the deceased."
