Ren Zai Mei Zong: Sweeping the Villains

Chapter 121 Inner Connections
Seeing Tang Ren's whereabouts, Li Qianlong knew the progress of the case.

Sure enough, someone was killed in a park the next day, and this time it was the liver that was poached.

At the scene, Li Qianlong also saw the forensic doctor.

James Springfield.

Famous surgeon.

He came to be a forensic doctor only as a volunteer, and he owns a hospital.

Springfield Hospital, the hospital building alone is beyond compare.

He and Chen Ying still knew each other, and they were talking at the moment.

I don't know if it's because of family friends or because of work?
Looking not very smart, as a well-known surgeon, it is easy for people to find out about left-handedness.

It's just an internal organ, and the right hand should be changed to minimize the risk.

The third homicide occurred. Because of several common features, the cases were formally combined for investigation.

It was another serial murder case, and the pressure was on the police station.

The most important thing now is to catch the murderer and avoid a fourth victim.

Otherwise they will be overwhelmed by the saliva of the citizens.

Under Chen Ying's proposal, the police had no choice but to mobilize human and material resources to analyze using Locard's exchange principle.

To put it simply, people and the environment are exchanging materials all the time, including traces, objects, impressions and so on.

When this principle is used in criminal cases, it is easy to find clues and lock targets.

However, those complicated tasks and the screening and analysis of a large number of objects must mobilize a lot of human and material resources, professionals, and various test instruments.

Some evidence is time-sensitive, too long an experiment will lose its meaning.

And now that time is running out, the next victim could appear at any moment, and chemical analysis laboratories across New York City must be activated.

This kind of authority is basically only available to the director general.

It's good to say that there is a result, if no clues are found, the blame will be inevitable.

But there is no other way now, and the director can only agree.

In fact, the murderer of this serial murder case was too smart, leaving no clues at the scene, and the murder targets could not find anything in common.

It looks like killing people randomly, but judging from all signs, he has a strong purpose in killing people.

Besides, if he continued to kill him like this, his position as the chief of the bureau might not be guaranteed.

He hates serial murders the most!
After two days of analysis, the results finally came out.

A substance that was not part of the context of the scene, sugar, was present at all three crime locations.

"That forensic friend of yours likes chewing gum very much, can't it be him?"

Li Qianlong laughed.

"Don't be kidding."

Chen Ying is very troubled now.

It's no wonder she can't think of it, James is a social elite, and this time the serial killer is basically Chinese.

"They are analyzing where the sugar comes from, maybe they can find the next crime location, what do you think?"

Seeing Li Qianlong reading a lot of materials, Chen Ying asked again.

"It's too difficult. It's like looking for a needle in a haystack. It's better to pay attention to the movements of those detectives. Maybe they have some clues that we don't have."

Locard's exchange principle is not so easy to use, otherwise there are no unsolved cases in this world?

What has happened may not be able to be detected, let alone what is speculated to have not happened?
Sugar is a very common thing, and its sources are too extensive, even if you lock the type traits, you may not be able to find the exact source.

Even if the source is determined, it is not necessarily the next place where the murderer committed the crime. He may be contaminated with these things anywhere.

If the murderer hadn't stepped on the next crime scene, it would be even more impossible to guess, because that fact didn't exist.

Taking a step back, even if the murderer stepped on the scene, New York is so big, how can he be sure where he went?That place must be his next murder location?

Accommodation, hotels, supermarkets, shopping malls, convenience stores, production sites of sugar factories, and even source farms of raw materials...

There are a large number of sugar production lines, from production to sales to use, which are too numerous to count.

If you really have the ability to investigate, you won't have to use so many analytical laboratories for so long at the three crime scenes.

Therefore, it is impossible for the police to speculate on the murderer's next murder location from this aspect, unless the substances present at the crime scene are too unusual and unique.

Besides, Li Qianlong knew that the murderer was a forensic doctor, and none of the three crime scenes could detect anything unique to the hospital, but instead detected the chewing gum he ate?

So he was more inclined that the police were also paying attention to the whereabouts of the detectives, got information from them, and then rushed to the sugar factory, and everyone bumped into each other.

"I'll pay attention."

Chen Ying nodded, now she can only try various methods to solve the case.

At least you don't have to pin all your hopes on the analysis in the laboratory, the chances are too slim.

Seeing that Li Qianlong was researching with a pile of materials, Chen Ying asked again: "Do you have any clues?"

Li Qianlong discovered that symbol before, and then wandered around without paying attention.

There is not much to be seen from the clues of the symbol, except that the murderer is probably a Chinese and has a lot of understanding of Taoist culture.

"I'm looking for the internal connection of the murderer's target, and I have some clues."

Li Qianlong listed some key information.

"Really? What's their connection?"

Chen Ying suddenly showed surprise on his face.

The most important thing in a serial murder case is the murderer's choice of target, and this internal connection is often the key to solving the case.

This serial murder case is because the victims can't find a trace of connection, so it makes everyone worry.

Even had to use a lot of manpower and material resources to analyze the crime scene in order to find more clues.

She has also read the victim's information countless times, but she can't find the slightest connection.

Now Li Qianlong said that he found it, if it is really confirmed, then the detection of the case will be a big progress!
"This kind of internal connection cannot be seen from your scientific perspective. I found that they are related to the five elements theory in Chinese culture."

Li Qianlong showed her the information of the victims.

"The first case was in the Hudson River. The victim was a white woman. The kidney was taken away. The time of the incident was from 7:27 p.m. to 28:[-] a.m. on July [-]. We discovered it on the morning of the [-]th. It belongs to water, and the kidney also belongs to water in the five elements."

"The second case was in Zaowang Temple. The victim, Wu Zhihao, had his heart taken away. Zaowang Temple belongs to fire, and the heart also belongs to fire in the five elements.

The third one is in the park, and it belongs to wood. The one that was taken away was the liver, which also belongs to wood, and all of them corresponded.

I will show my master the time when the crime happened and the date of birth of the victim. If I guess correctly, their fate and the time when they were killed belong to water, fire, and wood respectively! "
