Chapter 1585: Mustard

Translator: 549690339 

The police station in the capital was different from other local police stations. The resting rooms of the unit were all arranged with police officers on duty.

Moreover, because they were in the same city as the criminal Department, the police department did not arrange accommodation for Zhao Yu and the others.

In addition, the police station was far away from cui Lizhu or the Miao family’s mansion, so Zhao Yu had to pay out of his own pocket and get a room in the hotel opposite the police station.

At that moment, it was already threeo’ clock in the middle of the night. Zhao Yu had just taken a shower and was lying on his bed, but his mind was still racing, flashing back to all the details of the video murder case.

Zhao Yu knew that he couldn’t keep thinking like this. Since he knew that this would be a long tug-of-war, he had to maintain enough energy to deal with the future confrontation.

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

Perhaps, he had developed a reliance on sleeping pills. After using them, he immediately felt relaxed, and his tense nerves relaxed.

Hu …

He silently made up his mind that after solving this case, he would have to take good care of himself and not take medicine easily anymore.

Although the system’s items had no side effects, it was not a good habit to rely on drugs to force one to sleep.

After calming down, Zhao Yu finally had the time to look at his system interface again.

Although the hexagram area was still frozen and would take a long time to thaw, his adventure points had been steadily increasing.

In the past few days, with the various encounters he had while investigating the video murder case, his points had soared by more than 4000 points, and his total points had reached more than 17000 points, setting a record high.

At this rate, it would only take a few days before he could reach 100000 points and level up again.

Zhao Yu couldn’t help but be filled with anticipation. He wondered what kind of advanced functions would appear after the system was upgraded.

But …

Zhao Yu glanced at the devices in the device bar and thought to himself,”although there are quite a lot of devices, they aren’t very useful for the case at hand.”

Among all the devices, it seemed that only the memory flashback device might be of some use.

If he knocked Yun Duo’ er unconscious and used the memory flashback device to retrieve her memory fragments from the kidnapping and murder period, he might really be able to see the entire process of the case.

But …

Can this prop be used?

First, if he knocked Yun Duo’ er unconscious without permission, she might get hold of something that could be used against him, and it would be difficult to explain.

Second, the memory flashback device could only flash back five minutes of memory, and he didn’t have much left, only two. If he didn’t find the right time, it would be a waste.

Third, the video extracted by the memory replay device could only be watched by the person himself and could not be used as evidence in court.

At this point, Zhao Yu was already certain that Yun Duo’ er was the murderer, so there seemed to be no need to use the memory flashback device.

Besides, the images that flashed back to her memory flashback device were all scenes that Yun Duo’ er had seen herself. What was the difference between that and watching a murder video on a videotape?

Therefore, the most important thing now was to collect evidence and not rely on these unorthodox methods.

AI!

Zhao Yu sighed and thought that it would be great if he could get a hexagram now. No matter what hexagram he got, it would at least help him make a judgment.

Just like the devil case last time, even if the hexagram didn’t have a “Gen” hexagram, it meant that he was in the wrong direction, and he could try other ways without worry.

On the contrary, it could prove that his thinking was correct. But now, without the guidance of the hexagram, he felt a little lost.

As he was thinking, the sleeping pills began to take effect, and Zhao Yu quickly fell into a dreamless sleep.

……

When he woke up the next day, it was already past eight in the morning. Zhao Yu, who was worried about the case, did not even have breakfast and rushed back to the capital’s police Department.

“Team leader,” as soon as they entered the door, Zeng ke told Zhao Yu an important piece of news,”the comparison was successful. Yun Duo’ er’s DNA matches one of the DNA samples found in Kang Ziqing’s bag!”

“Oh?” Zhao Yu took Zeng ke’s test report, nodded, and said,”so, it’s the one with the least sample information.”

“Yes,” Zeng ke said.”It’s just a few bits of skin tissue!”

“Tsk tsk …” Zhao Yu quickly asked,”can you prove that the skin tissue was extracted from the videotape?”

“We can ‘t!” Zeng ke shook his head regretfully.”The tissue was found at the bottom of the bag, so it could have come from anything in the bag!”

“Damn it!” Zhao Yu was equally depressed.”If that’s the case, then this DNA is completely useless!”

“Yes.” Zeng ke nodded.”The woman was very cautious. When they collected evidence, the experts even opened the videotape and thoroughly checked it, but they still found nothing!”

“No fingerprints, no scurf,” Zhao Yu sighed.”Could it be that the woman was wearing gloves when she watched the video playback?”

“It’s possible …” Zeng ke said.”I guess she was guilty, so she didn’t dare to leave any information on the video. Even if someone found out, she could deny it!”

“Yes, that’s why she’s so arrogant and fearless!” Zhao Yu pondered for a moment, then said,”I’m starting to worry that even if we find more victims ‘bones, we still can’t do anything to her!”

“Well …” Zeng ke said with a worried look on his face.”I talked to Peipei this morning, um … On the phone with Dr. Zhang. She said that they didn’t find any other useful materials on Miao Xiaowen’s body, and they didn’t find any traces of clothing fibers.”

“In other words, they suspected that when the murderer buried Miao Xiaowen, he stripped her of her clothes and buried her naked underground!

“When the body was excavated, the forensic doctor judged that it might be Miao Xiaowen’s by the location of the knife wound on the skeleton!”

“I know,” Zhao Yu said, having already seen the autopsy report.”The murderer must have handled the body and the clothes separately, so that even if the body was exposed, it would be difficult to identify the body through the clothes.

“I already told cui Lizhu to dig around the area where Miao Xiaowen’s body was found!”

“But team leader, you haven’t seen this yet, have you?” Zeng ke handed over a document and said,”this is the latest test report that Peipei sent to me. The forensic scientists have found a chemical component called hydrazine enamine on the bones and in the pit where the bodies were buried!”

“Oh?” Zhao Yu was surprised and asked,”What is this?”

“It’s a chemical preparation used to synthesize organic materials,” Zeng ke said.”This thing has a strong pungent smell, a bit like mustard!”

“What? I didn’t hear it wrong, right?” Zhao Yu was even more surprised.”Mustard?”

“It just smells like mustard, but it has nothing to do with it!” Zeng ke explained,”at first, Peipei was not sure why there was such a chemical residue on the skeleton. It was not until she asked teacher Gao Facai that she finally understood what it was used for!”

“Oh?” Zhao Yu urged Zeng ke with his eyes.

“Team leader,” Zeng ke said patiently,”we took professional lessons in the police academy. Do you remember why a body had to be buried more than six meters deep?”

“Mm …” Although Zhao Yu couldn’t remember the contents of the professional course, he could guess the answer based on his feelings.”Because only those above six meters can make the professional search dogs unable to find them!”

“What about two meters?” Zeng ke asked again.

“Mm …” At this time, Zhao Yu had already thought of the answer from his previous memory.”Less than two meters, wild animals can smell it, and some hungry animals will dig up the body!

“Oh …” Zhao Yu suddenly realized the answer.”Miao Xiaowen’s body was only buried 1.5 meters deep, but no one has found it for 16 years …”

“Right!” Zeng ke nodded.”Gao Facai said that in the 1980s, there was a detective TV series called ‘Drake’ in Germany. In the TV series, there was an assassin who avoided the search of police dogs by smearing himself with isonamine!”

“So,” Zhao Yu’s eyes widened,”Yun Duo also learned this trick?

“She didn’t have the ability to dig a deep pit by herself. In order to avoid being dug up by wild animals, she applied a chemical reagent with a pungent smell to the body …

“This woman is so professional … Um … Wait …” Suddenly, Zhao Yu thought of something. He quickly opened his notebook, pointed to the names of the victims, and said,”could it be that Yun Duo’ er’s real weakness is here?!”
