Chapter 1584: Mustard

? The Metropolitan Police Department is different from other local police stations. There are all police officers on duty in the lounges that come with the unit.

Moreover, because it is in the same city as the Criminal Department, the Police Department did not arrange accommodation for Zhao Yu and others.

In addition, the police station was far away from Cui Lizhu or the mansion of the Miao family, so Zhao Yu had to pay for a room at the hotel opposite the police station.

At this moment, it was already more than three o'clock in the middle of the night, and Zhao Yu was lying on the bed after taking a shower, but his mind was still revolving, flashing back all the details about the video murder case.

Zhao Yu knew that he could no longer think hard like this. Since he already knew that this was a long tug-of-war, he had to maintain enough energy to cope with the future duel.

So, he had no choice but to use an invisible sleeping pill for himself to force himself to fall asleep.

Perhaps, he has become dependent on sleeping pills. After taking them, he immediately felt a burst of relief, and his tense nerves also relaxed.

call……

He silently made up his mind that after solving this case, he must take good care of himself, and he would never take medicine lightly again.

Although the system props have no toxic side effects, it is not a good habit to rely on drugs to force sleep.

After soothing his nerves, Zhao Yu finally had time to take a good look at his system interface again.

Although the hexagram opening area is still frozen and it will take a long time to unfreeze, his adventure points have been steadily increasing.

Over the past few days, with the various encounters in the investigation of the video murder case, his points have soared by more than 4,000 points, and his total points have reached more than 17,000 points, setting a record high.

At this rate of development, if you want to reach 100,000 points and then upgrade to a level, it is just around the corner.

Zhao Yu couldn't help but be full of longing. I don't know, what advanced functions will appear after the system is upgraded to another level?

But...

Zhao Yu glanced at the props in the props column, thinking to himself that although there are many props, they are not very useful for the case in front of him.

Looking at all the props, it seems that only the memory flashback device may still work.

if,

I made Yun Duo'er dizzy, and then used the memory flashback device to extract the memory fragments of her kidnapping and killing years, maybe I can really see what happened in the case.

But……

Can this tool be used?

First, if Yun Duo'er is unconscious, she may be caught by her, and it's not easy to explain;

Second, the memory flashback device can only flash back 5 minutes of memory, and there are not many left. There are only two left. If the time is not found correctly, it will be wasted.

Third, the video extracted by the memory flashback device can only be viewed by oneself, and cannot be used as evidence in court.

By now, Zhao Yu was certain that Yun Duo'er was the real murderer, so it seemed unnecessary to use the memory flashback device.

Besides, the images flashed back by the memory flashback device are also the shots that Yun Duoer saw by himself, so what is the difference from watching the murder video on the video tape?

Therefore, the top priority is to collect evidence, and we can no longer rely on these heretical ways.

well!

Zhao Yu sighed, and thought again, it would be great if he could open the hexagrams now, no matter what hexagrams were written, it would at least help him make a judgment.

Just like the demon case last time, even if the hexagram "Gen" is not written in the hexagram, it can show that you have gone in the wrong direction, and you can try other methods with confidence.

On the contrary, you can prove that your thinking is correct. But now, without the instructions from the hexagrams, I feel a little confused.

Thinking, thinking, the sleeping pill started to take effect, and Zhao Yu soon fell into a dreamless sleep...

...

When he woke up the next day, it was already past eight o'clock in the morning. Zhao Yu, who was worried about the case, didn't even bother to eat breakfast, so he hurried back to the capital police station.

"Team leader," Zeng Ke told Zhao Yu an important news as soon as he entered the door, "The comparison was successful. Yun Duo'er's DNA matched one of the DNA samples found in Kang Ziqing's purse!"

"Oh?" Zhao Yu took Zeng Ke's inspection report, nodded and said, "It turns out that it is the one with the least sample information."

"Yes," Zeng Ke said, "it's a few scattered dander tissues!"

"Tsk tsk..." Zhao Yu asked hurriedly, "Can you prove that these dander tissues were extracted from the video tape?"

"No!" Zeng Ke shook his head regretfully, "The dander tissue was found from the bottom of the purse, and it may come from any items in the purse!"

"Damn it!" Zhao Yu was also depressed, "In this case, it means that this DNA has no effect at all!"

"Yes," Zeng Ke nodded, "This woman is not usually cautious. When collecting evidence, the experts even opened the video tape and thoroughly checked the inside, but they still found nothing!"

"There are no fingerprints, and there are no skin flakes," Zhao Yu sighed. "Could it be...that bitch is also wearing gloves when watching the replays of the video?"

"It's possible..." Zeng Ke said, "I guess, after all, she has a guilty conscience, so she didn't dare to leave any information on the video tape, so that even if someone finds out, she can deny it!"

"Well, that's why she's so arrogant and confident!" Zhao Yu pondered and said, "I'm starting to worry now, even if we find more victims' bones, we won't be able to deal with her!"

"Well..." Zeng Ke said with a worried face, "I have already talked to Peipei, um... forensic doctor Zhang on the phone this morning. She said that they did not extract any other effective materials from Miao Xiaowen, nor Traces of attachment to fabric fibers are found.

"That is to say, they suspect that when the murderer buried Miao Xiaowen, she stripped off her clothes and buried her naked in the ground!

"When the body was excavated, the forensic doctor judged that it might be Miao Xiaowen's through the location of the knife wound on the bone!"

"I know," Zhao Yu said immediately after having read the autopsy report, "the murderer should have handled the deceased's body and clothing separately, so that even if the body happened to be exposed, it would not be easy to identify the body through the clothing of the deceased.

"I told Cui Lizhu a long time ago, let them dig up the area where Miao Xiaowen's body was found!"

"Team leader, but, you haven't seen this yet, have you?" Zeng Ke handed over a document and said, "This is the latest inspection report Peipei sent me. Here, a chemical component called allyl isothiocyanate was detected!"

"Oh?" Zhao Yu was slightly surprised, and hurriedly asked, "What is this?"

"It's a chemical preparation used to synthesize organic raw materials," Zeng Ke said. "This kind of thing has a strong pungent smell, a bit similar to mustard!"

"What? Did I hear correctly?" Zhao Yu was even more surprised, "Mustard?"

"It's just that the smell is similar to mustard, but it has nothing to do with mustard!" Zeng Ke explained, "At first, Peipei was not sure why there was such a chemical residue on the bones. It was not until I asked Teacher Gao Facai that I finally understood. What the hell is this thing for!"

"Oh?" Zhao Yu urged Zeng Ke with his eyes.

"Team leader," Zeng Ke said patiently, "We took professional courses in the police academy. Do you still remember why it is necessary to bury the corpse at a depth of more than 6 meters?"

"Hmm..." Although Zhao Yu couldn't remember the content of the professional course, he could guess the answer based on his intuition, "Because only a professional search dog can't find it if it is over 6 meters!"

"What about the two meters?" Zeng Ke asked again.

"Hmm..." At this time, Zhao Yu had already thought of the answer through previous memories, "If it is less than two meters, it will be smelled by wild animals, and some hungry animals will dig up the corpse!

"Oh..." Zhao Yu suddenly realized, and finally knew the answer, "Miao Xiaowen's body was buried only 1.5 meters deep, but it has never been found in 16 years..."

"Yes!" Zeng Ke nodded, "Forensic doctor Gao said that in the 1980s, there was a German detective drama called "Drake". The method on the corpse avoided the search of the police dogs!"

"So," Zhao Yu said with wide-eyed eyes, "this trick was also learned by Yun Duoer?

"She was unable to dig deep pits by herself. In order to avoid being dug up by wild animals, she applied a chemical agent with a pungent smell to the corpse...

"This woman is so professional...um...wait..." Suddenly, Zhao Yu suddenly thought of something, hurriedly opened his notebook, pointed to the names of many victims and said, "Could it be... Yun Duoer His real weakness—is right here!?”
