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

Lu Chuan nodded and said, "Record the tire marks as well, notify the traffic police, and ask them to help check for any light trucks that match the characteristics that have appeared in this area recently."

Of course, this is just a scene investigation scenario. As for the valuable intelligence provided by some clues collected during the scene investigation, it is still unclear whether the so-called light truck can be found or whether it can provide any directional help to the case.

However, just like every job, every link has a fixed procedure. As long as it is found during the on-site investigation, he must provide it. Qin Chuan knew this when he was just a criminal police officer doing on-site investigation. Whether these things can give Qin Chuan some direction and inspiration in the future case handling process depends on the future situation.

After several hours of intense investigation, they collected a large amount of physical evidence, including footprint plaster models, fiber samples, metal parts fragments, blood samples, and tire print photos, etc. These physical evidences were carefully packaged and prepared to be taken back to the police station for further testing and analysis.

"Captain Lu, the on-site investigation is almost complete. What should we do next?" Yang Lin asked.

Lu Chuan pondered for a moment and said, "Let's go back to the police station first and ask the technical department to conduct detailed tests and analysis on these physical evidences. Zhang Hui will go to the surrounding area to investigate and see if there are any new discoveries. We also need to start checking the recent missing persons information and try to identify the deceased as soon as possible!"

Because no clues pointing to the identity of the deceased were found at the crime scene, and no documents or other clues about the identity of the deceased were found, so at present, the most important thing is to determine the identity of the deceased, and the other thing is to perform an autopsy on the body of the deceased.

The giant corpse will affect the temporary judgment at the scene. Lu Chuan and his team can only make some superficial judgments when observing the body surface. However, the specific time of death, cause of death, and other conditions related to the deceased require autopsy to give accurate answers.

After Lu Chuan and others finished the surface inspection of the body, forensic doctor Zhang Kai immediately arranged two assistants to carry the body into the car with him. It can be basically confirmed that the scene of the crime is not the first scene. Of course, the specific situation depends on the comprehensive judgment of the forensic doctor. In addition, the judgment of the age of the deceased and other physical characteristics still need to be done by the forensic doctor to draw an accurate conclusion after the autopsy.

Zhang Kai stood in front of the dissection table, his eyes focused and calm, while the assistant beside him prepared the dissection tools in an orderly manner. The shadowless lamp illuminated the dissection table as bright as day, and the highly decomposed corpse looked particularly terrifying under the light, but Zhang Kai had long been accustomed to such scenes. He took a deep breath and began the meticulous dissection work, determined to obtain more key clues from this silent corpse.

Zhang Kai first conducted an in-depth examination of the deceased's head. He carefully cut open the scalp to expose the skull, and found an obvious fracture depression in the skull, and the surrounding brain tissue showed severe contusion marks. "Judging from the injuries to the head, this blow was extremely powerful, which directly led to brain death and was the direct cause of death of the deceased." Zhang Kai explained to his assistant while operating, and the assistant quickly recorded every detail. During the autopsy, Zhang Kai discovered that the deceased's appendix had been removed, and this information further enriched their understanding of the deceased. "The wound of the appendectomy operation healed well, and it should have been performed a few years ago. This can serve as a clue for our subsequent investigation of the identity of the deceased, and perhaps we can find relevant information about him from the hospital's surgical records." Zhang Kai said.

Then, Zhang Kai noticed that the deceased had a heart stent, which made him realize that the deceased may have suffered from serious heart disease. "The type of heart stent is relatively common, but we still have to record it, which is crucial to determine the identity and health status of the deceased. In addition, people with heart problems may need to take long-term medication in their daily lives. We can start from this aspect and investigate his medical records and drug purchase channels."

When examining the deceased's legs, Zhang Kai found that the right leg bone had a fracture. "This fracture should be old, and the healing of the fracture site shows that the victim received relatively professional treatment and recovered for a long time. This may help us narrow the scope of the investigation. For example, he may have been treated in a specific hospital, and we can check the relevant medical records." Zhang Kai carefully observed the fracture site and analyzed to his assistant.

After a series of rigorous and meticulous autopsies, Zhang Kai finally determined that the deceased had died 15 days ago. "Based on the degree of decay of the body, changes in the organs, and the test results of some physiological indicators, the deceased had been dead for about 15 days. This time point is very critical for us to investigate the suspect's movements and determine the timeline of the case." Zhang Kai took off his gloves and said to his assistant.

After the autopsy, Zhang Kai informed Lu Chuan of the results. After learning the news, Lu Chuan immediately organized Zhang Hui, Wang Shuai and others to conduct further investigations. "The identity of the deceased is our primary breakthrough. Zhang Hui, you continue to visit surrounding factories and companies, focusing on checking for people who meet the height and age characteristics of the deceased, and who have leg fractures, appendectomies, and medical records of heart disease. At the same time, pay attention to whether anyone has suddenly disappeared 15 days ago." Lu Chuan gave instructions to Zhang Hui.

"Understood, Captain Lu." Zhang Hui acted quickly. With relevant information about the deceased, he checked every factory and workshop, asking every worker if they knew such a person. He carefully checked the factory's employee files and did not miss any possible clues.

"Wang Shuai, you will be responsible for liaising with the hospital to find information on patients who have recently undergone appendectomy, heart stent surgery, and treatment for leg fractures, and compare it with the characteristics of the deceased. In addition, investigate whether anyone purchased special medications for treating heart disease around the time of the deceased's death." Lu Chuan turned to Wang Shuai and said.

"Okay, Captain Lu, I'll be there right away." Wang Shuai immediately contacted all the major hospitals, explained the situation in detail to the hospital staff, and requested assistance in the investigation. He carefully reviewed the hospital's surgical records and medical records, and made detailed records and analyses of every eligible patient.

Lu Chuan himself returned to the crime scene again, trying to find more clues related to the first crime scene. He searched carefully around the brick kiln, leaving no corner untouched. (End of this chapter)
