Previously, I mentioned that fracture lines caused by traffic accidents generally do not exceed three. However, this case clearly involved impacts from multiple directions. Based on contour comparison, I used 3D on-site modeling and restoration technology on the computer to analyze that the impacting object should have been a press. These machines are mostly used in gas production, but if modified, anything is possible.
You know how frightening the drones manufactured by that company were, with sharp blades and various hidden weapons. They have now been dismantled and are being studied in the forensic laboratory. I adjusted my head-mounted biological microscope, and with its help, I clearly saw all the wound tracks left on the victim. In addition to the previously discovered injuries, I also found that the pelvic bone area showed oblique edges. This proves that the victim had been shot, and the location was the pelvis. At that moment, he must have convulsed all over and suffocated from the pain.
This is because the bullet, after rapidly passing through the bone, creates a fracture. During the penetration process, it shrinks into a mushroom shape, pushing a conical mass of soft tissue in front of it. A bullet entry wound on the skull is generally smaller than the exit wound. As the bullet leaves the skull, it will reopen a ring of bone at the exit edge, leaving a perforation with beveled edges that are wider on the outside than on the inside. This shape resembles an inverted pyramid.
After taking photos, I found that the victim's situation at the time was truly tragic, with a clear mixed cause of death. Even the gunshot wound alone was enough to cause his demise, as the wound was extremely deep, essentially penetrating the entire body. I measured it with a steel ruler and, after calculating the exact data, the final step was the process of boiling the pubic bone.
However, there were no special findings. I then measured the victim's dental molds and skull contours. This would provide an additional metric if a matching person could be found from the missing persons list.
My part was almost finished, so I went to Ling Xiaotao. I found her also working on another skeleton. We had found quite a few remains in the public office area. Ling Xiaotao's examination was also nearing completion. She told me, "There are ballistic wounds on the spine. The deceased was shot before death. Since it's bone, much of the information cannot be investigated. However, I found some anesthetic components in the bone marrow. It's estimated that everyone in the public office was anesthetized before being shot. No wonder they all maintained the posture of lying on their desks. If it were a shooting incident, it wouldn't be a collective suicide."
Bone marrow collection. Stem cells can be collected from a donor's bone marrow or peripheral blood. If it is an autologous transplant, stem cells will be mobilized and collected from yourself in advance and stored. Now, sufficient bone marrow has been extracted from the skeletal remains at the scene to be sent for testing. I initially thought Ling Xiaotao would be slower, but now I see her speed is comparable to mine.
But who fired the gun? That is what we need to focus on.
Later, we discovered bullet fragments on some of the skeletal remains, as well as clear gunpowder residue. After collecting the bullets, the evidence collection was basically complete. Finally, combining all the skeletal test reports, we were surprised to find that some parts of these bones had bullet marks to varying degrees. They had all been shot. If the anesthetic could have spread through the ventilation louvers, then the shooter, based on the bullet marks, was firing from behind, at a distance of about 5 meters. So many people were hit in different areas; this likely couldn't have been done by just one person.
After all, the habit of firing a gun becomes ingrained. Even if one deliberately avoids angles and movements, they will revert to their habits after multiple shots. This is like handwriting analysis.
Combining all the ballistic traces on the bones, we deduced that at least five people were firing at the scene. This conclusion was reached based on data analysis of the trajectory angles, distances, and other factors.
Identifying so many people at once is an extremely tedious task. You may have heard of the World Trade Center attack. There were countless victims at that time, and many forensic anthropologists were deployed. A large number of victims were found, and the identification process took almost two years until everyone's identity was confirmed, and these unfortunate remains could finally return to their families.
What we are doing now is similar to the World Trade Center incident. With so many skeletal remains, a few days is far from enough. We asked the household registration department to investigate based on missing persons data. At that time, many families came to the provincial department to draw blood, extract DNA, and then try to match it with each skeletal remain. They all stated that their family members had worked at the drone technology company, which greatly increased the possibility of identifying the skeletal remains.
Subsequently, using a combination of dental molds, skull trajectories, and DNA comparison, we identified over twenty families who claimed the remains of the deceased. However, two skeletal remains remained unclaimed, and their families had not reported them missing in the missing persons data.
We had to temporarily put it aside, as Liang Manxiang's body still needed to be processed. Our verification revealed that she died from excessive blood loss due to multiple sharp-edged wounds to the head. He Xin, based on call records, confirmed that Liang Manxiang had indeed called me at the time. According to the current situation, Liang Manxiang was a victim.
It's quite embarrassing to think that we had mistakenly suspected her. The drone technology company was sealed off by us, but the results were shocking: the company's shareholders had all been murdered. One of them was the skeletal remain found on stage, and the others were also found in various corners of the company. Yet, Liang Manxiang had been working there all these years...
The thought of it makes us all feel a chill down our spines.
Criminal Case Discussion Meeting.
"Stop talking, this plot reminds me of some horror story, it's quite scary!" Gao Mingqiang said nervously.
"Are you referring to that Japanese horror film, the one called 'The Thirteenth Clinic'?" He Xin asked with a puzzled look.
"Yes, that woman, even though the hospital was closed, she kept going back to work, and it terrified her boyfriend. Are we going to encounter a supernatural case?" Gao Mingqiang said fearfully.
I sighed, "I thought you had changed from your old self, but why have you reverted recently?"
"This time is different. If you and Yuan De hadn't saved me then, we would probably be floating corpses in the sea right now!"
I said, "Yes, indeed. This case is not only bizarre, but an illegal drone technology company was also discovered within. Even though it was dismantled, Liang Manxiang's death is still suspicious. You know, after three years, if the company wasn't being operated by anyone, the electricity bills would have stopped being paid long ago..."
