"It seems you've been observing for a while."
"No, I just took a casual look and figured it out. My uncle said many villagers tried to persuade her back then. It's probably true. Wu Qingxia already had issues with her parents. Could this indicate she had a motive to kill them?"
"She killed her parents just like that? It seems a bit far-fetched!"
"I think so too, but if that's the case, this case can be separated. You know what I mean, right?"
"Exactly. Could it be a mere coincidence?"
"I absolutely don't think so. Let's investigate it thoroughly when we get back!"
"Alright!"
As we chatted, we got into the police car. On the way back, I noticed my uncle and other villagers standing behind us until we reached our village before they returned.
Before us lay three bodies. They were none other than Wu Qingxia's family. Now, with Wu Yisong, basically their entire family was lying here.
Facing these four corpses, I suddenly had a thought: was someone deliberately trying to kill their whole family? Could it be that man who escaped?
I was responsible for dissecting Wu Qingxia's body. The elderly couple's bodies were assigned to Xie Chuchu and Xiao Dong, respectively.
Turning on the exhaust fan and lights, I picked up the scalpel. I had already completed the preliminary work of drawing blood and collecting fibers. As I separated the deceased's chest, I discovered Wu Qingxia's lungs were very dirty, and the air sacs appeared to be completely diseased. She likely smoked heavily, and the kind of pipe tobacco favored by villagers.
Based on the current condition of her lungs, her smoking history was at least 10 years. However, strangely, we didn't find any pipe tobacco in her home.
I then examined her stomach and abdomen but found nothing unusual, followed by her private parts.
But it was the same. It was while examining the soles of her feet that I discovered a needle mark.
I shone a black light on it carefully and only then did I find it. I then sprinkled a considerable amount of seaweed ash on the deceased and discovered there was more than one needle mark on the soles of her feet. In total, there were about 5 across both feet.
They were all roughly the same size, indicating they were left by a syringe, just like the ones found on the previous two bodies.
Interesting. Perhaps this is the commonality between the bodies. We've finally found some clues.
I turned the deceased over and examined her back. The skin here was quite smooth but a bit dark. This is the typical complexion of a peasant woman, with thicker legs and arms than women in the city due to long hours of fieldwork. Her back of the head and earlobes had some scorch marks. Strange, these marks looked like they were left by falling cigarette ash.
Given the angle, she couldn't have done it herself. This could only mean there was another person in the room at the time.
I put down the scalpel, picked up the laser scanner and ultraviolet light, and shone them again. After confirming there were no needle marks or other findings on the deceased's back, I put away my tools. As a final step, I also examined the deceased's buttocks, and found that this area appeared to have been bitten by an animal.
I took photographs and compared them vigorously in the computer simulator. Finally, I identified it as a Tibetan Mastiff, a large and ferocious breed of dog. Its coat colors are mostly iron-clad gold, yellow, black (black is not pure black, but has slight white markings on the chest and limbs), and it originated from the Qinghai-Tibet Plateau. It has a strong temperament, is noble and arrogant, and possesses immense strength. This animal is formidable and I recall it being very fierce. It's likely Wu Qingxia was in excruciating pain at the time.
The wound had healed a bit by now, but the tooth marks were still clearly visible.
I don't know if this is related to the case, but I still included it in the autopsy report.
After finishing, I went to analyze the blood and extract DNA. The initial autopsy of this female body was complete.
I personally went to the laboratory and began working with some precision instruments. After the blood test results came out, I was surprised to find traces of hallucinogenic substances in her body.
Could this be why Wu Qingxia had the urge to kill? Reading.
But how did the hallucinogen get into her system?
As I was pondering this, Gao Mingqiang suddenly sent me a message, stating that he had found a pack of cigarettes Wu Qingxia had smoked. I immediately asked him to bring it back for the forensic team to examine. Indeed, the residual components in it contained hallucinogens.
It seems someone tampered with her cigarettes. I wonder how she obtained this pack.
We carefully examined it for fingerprints and found two sets. One set belonged to Wu Qingxia herself. The other set, upon comparison with the database, yielded no match.
Comparing it with the two old men, it turned out to belong to the elder. However, it's possible they just smoked the same pack of cigarettes. After all, the elder wouldn't let his daughter become hallucinated and kill herself, would he?
This logic is completely flawed.
Excluding the elder, we could only try to investigate the source of Wu Qingxia's cigarettes. This was a pack of Zhonghua cigarettes, which villagers rarely bought because they were too expensive. They preferred to make their own tobacco and smoke it from large pipes.
This pack of cigarettes was likely a gift from someone.
When I left the forensic department, I formally asked He Xin to investigate Wu Qingxia's recent movements and the surveillance footage around her house.
After a series of investigations, it was discovered that the day before Wu Qingxia's death, a salesman had visited her home to sell cigarettes. The Zhonghua cigarettes were sold at that time.
Wu Qingxia then bought them, unknowingly leading to her killing her entire family.
However, there's still a question. She appeared to be murdered, not a suicide. That's strange. Then who entered and killed Wu Qingxia afterward?
Given the circumstances of Wu Qingxia's house, many areas were not covered by surveillance. The killer likely escaped from a blind spot after finishing. There were no suspicious footprints, fingerprints, or hair evidence at the scene, indicating the perpetrator was very skilled and left no traces.
Forget it. It's likely that Wu Qingxia's lead is dead. At most, we can only find the cigarette salesman.
The guy didn't avoid the surveillance cameras. His face was visible in many locations. I told Gao Mingqiang, "Bring this guy in first!"
"I've already sent people to handle it. This guy seems unaware of anything. He was gushing about his products when he was selling them, not like someone sinister and cunning!"
Judging from the surveillance footage, that's indeed the case. However, I still need to see this salesman in person to be sure.
About 30 minutes later, a police officer reported that they had found the guy. His name was Ai Qiran.
