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

At 0:30, the vehicle arrived at the autopsy room of the Provincial Criminal Investigation Detachment. Located on the basement floor of the detachment building, the room occupies approximately 100 square meters. The interior is simply and solemnly decorated, with white walls and floors. The smell of disinfectant permeates the entire room, creating a slightly chilly atmosphere. In the center of the room stands an autopsy table, above which hangs a high-intensity shadowless lamp, its bright light illuminating every detail on the table. Beside the table are various autopsy tools, including scalpels, forceps, scissors, probes, measuring cups, a balance, and a microscope. All tools have undergone rigorous sterilization and are neatly arranged on the tool table.

Forensic pathologist Zhang Kai had been waiting in the autopsy room for some time. Dressed in a white autopsy gown, mask, gloves, and goggles, his expression was serious and his eyes focused. Having worked as a forensic pathologist for many years, he had handled countless autopsies in homicide cases. Experienced and meticulous, he was able to find crucial clues to identify suspects and uncover the truth of cases from subtle changes in the body. His assistant, Xiao Lin, 25 years old, was a recent graduate. Although inexperienced, she was diligent and meticulous, constantly learning from Zhang Kai and assisting him in completing autopsies.

"Teacher Zhang, the body has arrived. Can we begin the autopsy?" Xiao Lin asked Zhang Kai as soon as he saw the staff carrying the body bag onto the autopsy table. He immediately stepped forward to help the staff place the body bag steadily, then turned to Zhang Kai and asked, his tone a mix of nervousness and anticipation.

Zhang Kai nodded, his gaze falling on the body bag on the autopsy table. He said seriously, "Alright, let's begin. First, we'll conduct a preliminary external examination of the body to confirm its basic information. Then we'll proceed with the autopsy, focusing on the internal organs to determine the time and cause of death. We'll also search for any clues that could identify the deceased, as well as any trace evidence pointing to the suspect. Remember, the entire autopsy process must be meticulous and thorough; no detail can be overlooked. Make detailed records, take autopsy photos and videos, and ensure the authenticity and accuracy of the autopsy results."

"Understood, Teacher Zhang!" Xiao Lin nodded seriously, immediately took out the autopsy record book and camera, and prepared for the work. At the same time, he assisted Zhang Kai in carefully opening the body bag. The body bag was slowly opened, and the deceased's body was fully presented on the autopsy table. The light from the operating lamp shone on the deceased, illuminating the details of the deceased's appearance and clothing clearly.

Zhang Kai stepped forward and carefully examined the deceased's body. As he examined it, he said to Xiao Lin, "Xiao Lin, please record the basic physical characteristics of the deceased. The deceased is male, with an estimated age of 30 to 35 years old, approximately 175 cm tall, of medium build, well-proportioned, and without any obvious deformities. His hair is black, about 5 cm long, messy, covered with dust and a small amount of cement powder, and has a stiff texture. His facial expression is stiff, his eyes are wide open, his conjunctiva is congested, his cornea is slightly cloudy, his lips are cyanotic, there are no foreign objects in his nasal cavity or oral cavity, and his teeth are all present, not missing, not loose, and without obvious cavities."

While taking careful notes and nodding, Xiao Lin used his camera to photograph the deceased's face from multiple angles to ensure that every detail was clearly recorded. "Teacher Zhang, there are no obvious external injuries on the deceased's face, only a bruise on the forehead with slight swelling around it, which is consistent with what was found during the on-site investigation," Xiao Lin said, pointing to the deceased's forehead.

Zhang Kai nodded, gently pressing the bruise on the deceased's forehead with his fingers, carefully feeling its hardness and extent. He said, "Hmm, this bruise is irregularly shaped, about 3 x 4 centimeters in area, and dark purple in color. It has no obvious elasticity when pressed, suggesting it was caused by a blunt force impact. The impact force was moderate, and there was no skull fracture. We cannot determine the specific type of blunt force for the time being. Please write this down: one blunt force injury to the forehead, 3 x 4 centimeters, dark purple, no skull fracture."

Zhang Kai then continued to examine the deceased's neck. He gently pressed the neck with his fingers and carefully examined the skin. He said, "The neck skin is intact, with no obvious ligature marks, strangulation marks, needle marks, knife wounds, or other external injuries. The thyroid gland is not enlarged, the trachea is not displaced, and the cervical lymph nodes are not enlarged. The possibility of death by asphyxiation due to external pressure on the neck has been preliminarily ruled out."

“Teacher Zhang, the deceased’s hands were clenched into fists, and there were small amounts of black fibers and dust between the fingers. The on-site investigators have already collected samples of these fibers and dust. Should we collect another sample for further testing?” Xiao Lin asked, carefully examining the deceased’s fingers with tweezers as he spoke.

“Yes, we can take a sample and compare it with the sample taken from the scene to confirm whether they are consistent. At the same time, we can analyze the material and source of the fibers, which may provide clues for solving the case,” Zhang Kai said. “In addition, we should carefully examine the deceased’s fingers to see if there are any broken nails, broken skin, or other details. These details may reflect whether the deceased had a struggle with the suspect before his death.”

Xiao Lin immediately followed Zhang Kai's instructions, carefully using tweezers to extract fiber and dust samples from between the deceased's fingers, placing them in a sealed bag, labeling it, and then carefully examining the deceased's fingers. "Teacher Zhang, the deceased's fingernails are intact, without breakage or damage. Apart from black fibers and dust, no other foreign objects or skin tissue residue were found in the fingernail crevices. It is speculated that the deceased may not have had a fierce struggle with the suspect before death, or that the struggle did not cause any damage to the fingernails."

Zhang Kai nodded and continued examining the deceased's torso and limbs: "Continue recording. The deceased was wearing a black cotton coat, covered in dust and cement powder. The cuffs and hem were torn, with uneven edges, presumably from external force. There were no obvious stains on the inside of the coat, and the pockets were empty. No items that could identify the deceased were found."

"The deceased was wearing dark cotton jeans, which were also covered in dust and mud. The cuffs showed obvious signs of wear, with uneven edges, presumably from prolonged wear or friction. The pockets were empty. The deceased was also wearing black sneakers with clearly defined rubber soles. The uppers had small amounts of black oil and cement powder on them, similar to the soles of the suspicious footprints found at the scene. The shoelaces were loosely tied, and there was a small amount of dust and fibers on the tongues." (End of Chapter)
