"Look..." Zhao Yu pointed to the victim's name on the whiteboard and patiently said to Simona, "When we judge and weigh a murder case in which the deceased is a young woman, whether there has been any violation is often the most important factor. standard!
"Take the case at hand as an example. In the three murder cases, two of the victims showed signs of being violated. The third victim has not yet had an autopsy. Her condition is probably the same as the first two.
"Let's think about it from the criminal's perspective. He caught the victim, assaulted her and then killed her. What does that mean?"
"It means..." Simona guessed actively, "It means the murderer is a man!"
"Yes, are there any more?" Zhao Yu asked again.
"Also..." Simona guessed carefully and added, "The murderer has a psychological problem and is depressed. He wants to rely on violation and murder to release his emotions..."
"Not bad," Zhao Yu then asked, "Is there any more?"
"And..." Simona thought about it again and said, "The murderer... um... um... "
Simona hesitated for a long time, but did not say a complete sentence.
“Also,” Zhao Yu said, “for us criminal investigation workers, cases of violations are often solved faster!
"Because the murderer intends to invade, and as long as he violates, he will leave ironclad evidence. Now that technology is so advanced, it is easier for our police to detect!
"In other words," Zhao Yu pointed at the whiteboard, "If there was no violation in these three cases, it means that the problem is serious, do you understand?"
"Oh...are these the details you were talking about?" Simona asked, "Since the deceased was violated, wouldn't this case be solved soon?"
“On the contrary,” Zhao Yu said, “If it was really so easy to break, the local police wouldn’t have waited for me to come!
"The details I'm talking about don't mean violations," Zhao Yu came to the whiteboard and said solemnly, "There are details in this case that I least want to see!
"Explanation, this case is very difficult. My detective Zhao Yu may have met another criminal master!!"
"Then..." Simona asked curiously, "What details are you talking about?"
"The details are," Zhao Yu finally said the answer, "Although the victim may have been violated, no substances related to the murderer were extracted during the autopsy. This has never been encountered before. Many!"
"Wait..." Simona digested Zhao Yu's words carefully, and then said after a while, "You mean, although the victim was violated, no substances related to the murderer were extracted, right
"What substance? Body fluids, hair, dander tissue and DNA?" Simona's eyes widened. "Since these substances cannot be found, why do we say that the deceased was violated?"
"Yes, this seems very contradictory!" Zhao Yu said, "I have carefully checked that although the autopsy technology in Manzhou is not as good as that in big cities, it is not a stupid mistake!
“The first two deceased persons all showed signs of being violated, as evidenced by congestion, contraction and some blood characteristics.
"Moreover, these are enough to show that the deceased was violated during his lifetime..."
"But," Simone was puzzled, "Wearing... Wearing that? Why is there no liquid left?"
"Yes, the autopsy personnel detected the components of glycerin and sodium hyaluronate," Zhao Yu said, "These are the components of lubricating oil..."
"Oh..." Simona said, "So... it's an assault with a condom?"
“But,” Zhao Yu said, “even if a condom was worn, there should still be some hair or dander tissue left behind. However, the forensic doctor carefully inspected the body but found nothing.
"They suspect," Zhao Yu said, "that the murderer made careful preparations before and after..."
"Careful preparations?" Simona was curious, "What preparations?"
“Preparing the skin (shaving off body hair) in advance,” Zhao Yu said, “After finishing the work, he washed the victim carefully...
"Or..." Zhao Yu added, "He did not actually physically assault the victim, but used some tools or supplies, and then deliberately interfered with us..."
"Oh..." Simona nodded and said, "You are so careful... It seems that you have really met your opponent!"
"It's not just that," Zhao Yu said again, "This person is very familiar with the environment in Manchuria. Take the first two cases as an example. If he really arrived at the crime scene from the river on a sledge, how long would it take for him to arrive at the crime scene? Wherever there are surveillance cameras installed, his influence should be left behind!
"However, Captain Qiu has sent people to check several times, but nothing was found...
"Also," Zhao Yu continued, "there were no suspicious substances found on the expansion tubes, hooks, and ropes. This person must be difficult to deal with!"
"Yeah..." Simona swallowed and felt a thrilling feeling. She thought about it seriously and echoed, "This case is really more complicated than I thought!
"If my previous guess was correct and the murderer didn't want to see them living in Manchuria, then could it be that these victims were randomly selected by the murderer?"
"Yes, this is exactly what I am worried about," Zhao Yu nodded and said, "If the murderer has no close relationship with the deceased and he chose them randomly, then this case will only be more difficult!
"I'm afraid, I can only impose city-wide martial law... However, city-wide martial law only treats the symptoms but not the root cause... If this criminal cannot be caught, he will definitely take action again. Maybe he won't be in Manzhou next time... "
"God," Simone said, "there is actually... there is such a murderer... What is she doing for this? Has this person been stimulated by something?"
"So, I'm more interested in your guess," Zhao Yu said, "Look... the murderer just violated and killed people. In the ice and snow, if he killed someone, he just buried it wherever he wanted and hid the body, then Hard to spot!
"However, the murderer ignored the cold weather and insisted on transporting the body to a remote place under a bridge. He also hung the deceased up and did not even give her clothes to wear. What does this mean?"
"Explanation..." Simona said with fear, "It means that the murderer not only wanted to kill the deceased, but also humiliated the deceased. It is like a ritual in feudal society. It not only kills people, but also tortures the heart..."
"This case..." Zhao Yu said, "From the beginning, I smelled full of hatred!
"For detection, this means two extremes," Zhao Yu said, "If the murderer's hatred comes from these victims, then we should be able to lock him in soon!
"But what if the murderer is only angry at others because of the personal harm he suffered? That would be... trouble... "
