Crazy Detective

Chapter 2360

"Look..." Zhao Yu pointed to the victim's name on the whiteboard and patiently said to Xi Mengna, "when we judge and measure the murder of a young woman, whether there is infringement is often the most important standard!

"Take the current case for example. In the three murders, two victims have found traces of violations, and the third victim has not yet undergone an autopsy. It is estimated that her situation is the same as that of the first two.

"Let's think from the perspective of the criminal. He caught the victim, violated her first, and then killed her. What does that mean?"

"Explain..." Xi Mengna guessed positively, "it shows that the murderer is a man!"

"Yes, anything else?" Zhao Yu asked again.

"And..." Xi Mengna guessed carefully and said, "the murderer has psychological problems and depression. He wants to release his emotions by aggression and murder..."

"Yes," Zhao Yu continued, "is there anything else?"

"And..." Xi Mengna thought hard again and said, "the murderer... Um... Um..."

Simona hesitated for a long time, but she didn't say a complete word.

"What's more," said Zhao Yu, "for our criminal investigators, cases of infringement tend to be solved faster!

"Because the murderer intended to invade, as long as the invasion will leave iron evidence. Now the technology is so developed that it is convenient for our police to detect!

"That is to say," Zhao Yuyi pointed to the whiteboard, "if there is no violation in these three cases, it shows that the problem is serious, okay?"

"Oh... Is that what you said?" Simona asked, "since the deceased was violated, won't this case be solved soon?"

"On the contrary," said Zhao Yu, "if it's so easy to break, the local police won't wait for me!

"The details I'm talking about don't mean infringement," Zhao Yu said solemnly when he came to the whiteboard. "There are the details I don't want to see in this case!

"It shows that this case is very difficult. My detective Zhao Yu may have met another crime expert!!"

"Well..." Xi Mona asked curiously, "what are the details you said?"

"The details are," Zhao Yu finally gave the answer. "Although the victim may have been violated, no material related to the murderer was extracted during the autopsy, which has never been encountered before!"

"Wait..." Xi Mengna digested Zhao Yu's words carefully and said for a long time, "do you mean that although the victim was violated, no material related to the murderer was extracted, didn't you?

"What substance? Body fluids, hair, dandruff tissue and DNA? " Xi Mengna stared, "since we can't find these substances, why do we say that the dead were violated?"

"Yes, this seems very contradictory!" Zhao Yu said, "I've carefully checked it. Although Manchuria's autopsy technology is not as good as that of big cities, it's not going to make low-level mistakes!

"The first two dead showed signs of invasion, congestion, contraction and some blood characteristics.

"Moreover, these are enough to show that the deceased was violated before his death..."

"But," Simona wondered, "are you wearing... That? Why didn't you leave the liquid? "

"Yes, the autopsy personnel detected the components of glycerol and sodium hyaluronate," Zhao Yu said. "These are the composition of lubricating oil..."

"Oh..." Xi Mengna said, "so... It's an infringement with a condom?"

"But," said Zhao Yu, "even if you wear a condom, you should leave some hair or dandruff tissue. However, the forensic examined the body carefully, but nothing was found.

"They suspect," said Zhao Yu. "The murderer made careful preparations before and after..."

"Careful preparation?" Simona wondered, "what are you going to do?"

"Prepare the skin in advance (shave off the body hair)," said Zhao Yu. "After he finished, he cleaned the victim carefully

"Or..." Zhao Yu added, "he didn't really infringe on the victim by physical contact, but used some tools or supplies, and then deliberately interfered with us..."

"Oh..." Xi Mengna nodded, "so careful... It seems that you really met your opponent!"

"Not only that," Zhao Yu added, "this man is very familiar with the environment of Manchuria. Take the first two cases. If he really arrived at the crime scene from the river by climbing a plow, his influence should be left in several places where camera monitoring is installed!

"However, Captain Qiu has sent someone to check it several times and found nothing

"Also," Zhao Yu continued, "there are no suspicious substances found on the expansion pipe, hook and rope. This person must be difficult to deal with!"

"Yes..." Xi Mengna swallowed her saliva and had a thrilling feeling. She thought about it carefully and echoed, "this case is really more complicated than I thought!
