"Zeng Ke," Zhao Yu pressed Zeng Ke's shoulders excitedly and asked, "Why did Yun Duo'er apply a pungent smelling chemical reagent to the corpse?"
"Well..." Zeng Ke replied, "Didn't we just discuss it? Yun Duo'er painted it in order to prevent the body from being dug up by animals..."
"No!" Zhao Yu reorganized his words and asked, "What I'm talking about is, how does Yun Duo'er know that applying that kind of chemical reagent to the corpse can prevent animals from digging up the corpse?"
"Hmm..." Zeng Ke pondered the answer, "It's hard to say. Maybe she has also watched the TV series?"
"That's not right," Zhao Yu pinched her chin and said again, "I mean, Miao Xiaowen was the fourth victim, and Yun Duoer already had some experience when he killed her...
"But, what about before that? Were all the other corpses smeared with chemical reagents?"
"Hmm... oh..." Seeing Zhao Yu's excited look, Zeng Ke seemed to have thought of something, but still didn't think of anything.
"You said..." Zhao Yu pressed Zeng Ke's shoulders hard and said seriously, "Did Yun Duoer miss the mark when he first killed someone!?"
"Ah?" Zeng Ke finally understood what Zhao Yu meant, "You mean... Yun Duoer had an accident before when she was killing people and burying corpses? That's why... she thought of using allyl isothiocyanate
"So... what accident happened?" Zeng Ke said at a loss, "The body she buried before was exposed because it was not buried deep enough?"
"Hmm..." Zhao Yu quickly came to a blank whiteboard, drew a circle on it with an oil pen, and said, "I think so too. Yun Duoer had no experience when he first started killing people, so maybe he simply dug The body was buried in a pit!
"But... not long after the body was buried, some animal dug it out..."
"But..." Zeng Ke objected, "How did she know that the body was dug out by animals? Could it be... that after killing someone and burying the body, she would often return to the burial site to check!?"
"No!" Zhao Yu denied, "There are very few such cases. Only those murders with strong emotional bonds will cause the murderer to return to the murder scene repeatedly.
"Either out of guilt, wanting to pay homage, or looking for psychological comfort or something... However," Zhao Yu frowned and said thoughtfully, "There is no emotion at all between Yun Duo'er and the victim, and she herself is so cold-blooded type, so it is unlikely to return to the murder scene...
"Besides... she recorded the murder video! If you want to recall your murder process, don't you just go home and watch the video?"
"Then... if you don't return to the scene, how do you know that the body was exposed?" Zeng Ke said casually, "Could it be that... after the body was dug up by animals, it was first discovered, then reported to the police, and then made it to the news
"Did Yun Duo'er learn from the news that the body she killed could be dug out by animals? So, when she kills people again in the future, she comes up with a clever trick to use chemical reagents?"
Zeng Ke finished this general speculation in one breath. After finishing speaking, he and Zhao Yu both fell silent, and the atmosphere seemed a little tense and a little embarrassed.
"Well..." After waiting for a long time, Zeng Ke covered his face and said, "Team leader, is my imagination a little too rich
"Yun Duo'er is so cautious. Just in case, she has been prepared since the first time she killed someone. She has already thought of chemical reagents?"
"That's what I said, but..." Zhao Yu opened his notebook, quickly checked the records, and said, "Li Feifan said that the camera was purchased in Tokyo in the first half of 1999.
"Wei Qiqi, the first victim in the video case, was killed in the second half of 1999, more than three months apart..." Zhao Yu pondered and said, "Then... can we assume that before Wei Qiqi, Yun Duo Have you ever killed anyone
"It's just that at that time, because I hadn't purchased a camera yet, I didn't record the video?"
"Hmm..." Zeng Ke hesitated and asked, "Are you really checking?"
"Check!" Zhao Yu said decisively, "Don't let go of any idea! We can check. From the time when Yun Duoer and Li Feifan got married to the time when Wei Qiqi was killed, there were still people around the couple. Are there any other missing girls
"Zeng Ke," Zhao Yu added, "have you noticed that if your hypothesis just now is true, then it may not be difficult to investigate this unknown murder case!
“First of all, they hadn’t been married very long when they bought the camera.
"Secondly, the couple were still busy building a film and television company at that time, and they were basically operating in Beicang City, Xijiang Province. You can focus on searching the local case records to see if there are any cases that match the characteristics of the video murder case
"For example, after a girl disappeared, she was killed and buried, and then the body was accidentally discovered, and then the case has not been solved to this day..."
"Oh... oh..." Zeng Ke nodded, "I understand, I'll do it right away! But the team leader... has something to say, I don't know whether to say it or not?"
"explain!"
"Even if there is such a case and there is a corpse dug out by animals, it was more than 20 years ago," Zeng Ke said worriedly, "Don't say we can find clues from the corpse. That corpse It’s impossible to still keep it, right
"Don't forget, we didn't even harvest Miao Xiaowen's bones..."
"Wrong!" Zhao Yu interrupted him and said, "A serial killer's weakness is often found the first time! As he kills more people, he will become more and more mature.
"Yun Duo'er is a person who is constantly improving! If we want to catch her weaknesses, we have to work hard from her first time!
"Zeng Ke," Zhao Yu pressed Zeng Ke's shoulder again and said, "If our guess is true, then the police will definitely leave evidence samples of that body.
“Maybe we can find something exciting for us in these samples!
"This seems a bit ridiculous, but what if we are really right?"
"Hmm... Okay, I'll do it right away!" Following Zhao Yu's explanation, Zeng Ke became more energetic and turned around to arrange the task.
Unexpectedly, as soon as he turned around and walked away, someone knocked on the office door.
Zeng Ke happened to walk to the door and opened it casually.
"Sir," Dan saw a local police officer reporting to Zeng Kehui with a tablet computer in his hand, "I think you need to take a look at this..."
As he said that, the police officer turned on the play button on the computer screen, and a deep and gloomy sound of music suddenly came from inside.
Out of curiosity, Zhao Yu also walked over to watch, only to see a movie clip being played on the tablet computer.
"The name of this movie is "Evil Love"," the police officer pointed at the screen and introduced, "It was filmed in the early 1990s, and Yun Duo'er is the heroine of this movie!
"Yun Duo'er had just debuted at the time and was not famous at all. Not only was this film made with a low budget, but the story was too dark and it was banned!"
During the police introduction, Zhao Yu and Zeng Ke had already seen the footage of Yun Duoer appearing in the movie screen.
But I saw Yun Duoer holding a knife in his hand, and then stabbed a girl who was tied up and unable to move...
