Chapter 1586

The capital police department is different from other local police stations. The rest rooms brought by the unit are all equipped with police officers on duty.

Moreover, because it is in the same city as the criminal department, the police department has not arranged accommodation for Zhao Yu and others.

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

At the moment, it was more than three o'clock in the middle of the night. Zhao Yu was lying in bed after taking a bath, but his mind was still walking like a lantern, flashing all the details of the video murder.

Zhao Yu knows that she can't think so hard anymore. Since she already knows that this is a long tug of war, she must maintain enough energy to cope with the future duel.

So he had to use an invisible sleeping pill to force himself to sleep.

Perhaps he has become dependent on sleeping pills. After using them, he suddenly feels relaxed and his tight nerves relax.

Hoo

He made up his mind silently. After solving the case, he must take good care of himself and can no longer take medicine easily.

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

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

Although the kaigua area is still frozen and will take a long time to thaw, his adventure points have been growing steadily.

In recent days, with the investigation of various experiences of video homicide, his points have soared by more than 4000 points, and the total points have reached more than 17000 points, a record high.

At this rate, if we want to reach 100000 points and upgrade one level, it is just around the corner.

Zhao Yu can't help but be full of longing. I don't know. What advanced functions will appear after the system is upgraded again?

But

Zhao Yu scanned the props in the props column and thought that although there were many props, they didn't play a big role in the current case.

Looking at all the props, it seems that only the memory flasher may be able to function as a starting point.

If you confuse yunduo'er and then use the memory flashback to extract the memory fragments of her kidnapping and murder, you may really see the course of the case.

But

Can you use this prop?

First, if you dizzy the clouds without authorization, she may catch the handle, which is not easy to explain;

Second, the memory flashback can only flash back 5 minutes of memory, and there is not much left. At present, there are only two left. In case you don't find the right time, it will be wasted.

Third, the video extracted by the memory flashback can only be seen by yourself and can not be used as evidence in court.

Up to now, Zhao Yu can be sure that yunduo'er is the real murderer, so it seems unnecessary to use the memory flashback again.

Besides, the pictures flashed back by the memory flasher are also the shots seen by yunduo'er himself. What's the difference between watching the killing video on the video tape?

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

Alas!

Zhao Yu sighed and thought to himself, if only he could open divination now. No matter what divination text he wrote, he could at least help himself make judgment.

Just like the devil case last time, even if the divination text does not issue the "gen" divination, it can show that you have found the wrong direction and can safely try other methods.

On the contrary, you can prove that your idea is correct. But now, without the instructions of divinatory symbols, I feel a little confused.

Thinking, thinking, sleeping pills began to work, and Zhao Yu soon entered dreamless sleep

……

When he woke up the next day, it was already past 8 a.m. Zhao Yu, who was worried about the case, couldn't even eat breakfast, so he hurried back to the capital police department.

"Team leader," Zeng Ke told Zhao Yu an important message as soon as he entered the door, "the comparison was successful. Yunduo's DNA matched one of the DNA samples found in Kang Ziqing's bag!"

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

"Yes," said Zeng Ke, "it's some scattered dandruff tissue!"

"Tut tut..." Zhao Yu asked hurriedly, "can you prove that these dandruff tissues were extracted from the video tape?"

"No!" Zeng Ke shook his head regretfully, "those dandruff tissues were found at the bottom of the bag, possibly from any item in the bag!"

"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 generally cautious. When collecting evidence, experts even opened the video tape and checked it thoroughly, but she still got nothing!"

"There are no fingerprints, no dandruff," Zhao Yu sighed. "Is it... Does this woman wear gloves when watching the video playback?"“ It's possible... "Zeng Ke said," I guess she's guilty after all, so she doesn't dare to leave any information on the video tape, so even if someone finds out, she can deny it! "“ Well, that's why she is so arrogant and confident! " Zhao Yuzhuo thought and said, "I'm worried now. Even if we find more victims' bones, we can't do her!"“ Well... "Zeng Ke said with a worried face," I talked to Peipei, um... I talked to forensic Zhang on the phone this morning. She said that they didn't extract other effective materials from Miao Xiaowen, and they didn't find any traces of clothing fibers“ In other words, they suspect that the murderer stripped off Miao Xiaowen's clothes and buried her in the ground“ When the body was excavated, the forensic medicine judged that it might be Miao Xiaowen's through the position of the knife wound on the bones! "“ I know, "Zhao Yu had already read the autopsy report and said immediately," the murderer should treat the dead body and clothes separately, so even if the body happens to be exposed, it is not convenient to identify the body through the dead's clothes“ I told Cui Lizhu long ago to let them dig again near the bones of Miao Xiaowen! "“ Chief, but you haven't seen this yet? " Zeng Ke handed over a document and said, "this is the latest inspection report sent to me by Peipei. The forensic medicine detected a chemical component called allyl isothiocyanate on the bones and in the pits where the bodies were buried!"“ Oh? " Zhao Yu was a little surprised and hurriedly asked, "what is this?"“ "It's a chemical used to synthesize organic raw materials," Zeng Ke said. "This kind of thing has a strong pungent smell and is a bit similar to mustard!"“ what? Did I hear you right? " Zhao Yu was even more surprised, "mustard?"“ It just smells like mustard, but it has nothing to do with mustard! " Zeng Ke explained, "at the beginning, Peipei was not sure why there were such chemical residues on the bones. It was not until he asked the rich teacher that he finally understood what this thing was used for!"“ Oh? " Zhao Yu urged Zeng Ke with her eyes“ Group leader, "Zeng Ke said patiently," we had a professional class in the police academy. Do you remember why we need to bury the body more than 6 meters deep? "“ Well... "Although Zhao Yu can't remember the content of the professional course, she can guess the answer by feeling," because only a professional search dog can't find it if it's more than 6 meters! "“ What about the two meters? " Zeng Ke asked again“ Well... "At this time, Zhao Yu thought of the answer through her previous memory," if it is less than two meters, it will be smelled by wild animals, and some hungry animals will dig out the corpse“ Oh... "Zhao Yu suddenly realized and finally knew the answer." Miao Xiaowen's body was only buried 1.5 meters deep, but it has never been found in 16 years... "Yes!" Zeng Ke nodded. "Gao FA said that in the 1980s, there was a detective TV play called Drake in Germany. In the play, a killer used the method of smearing allyl isothiocyanate on the body to avoid the search of police dogs!"“ So, "Zhao Yu said with wide eyes," this move has also been learned by Yunduo“ She was unable to dig a deep pit alone. In order to avoid being dug and planed by wild animals, she smeared the body with chemical reagents with pungent smell... "This woman is so professional... Um... Wait..." suddenly, Zhao Yu suddenly thought of something. She quickly opened her notebook and pointed to the names of many victims, "Is... The real weakness of the clouds - right here?"
