Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 568 Lu Chuan’s Judgment

Lu Chuan continued his analysis.

"These two traces appeared in two cases at different times and at different scenes, and they can completely overlap, indicating that they are definitely not accidental traces."

"I suspect that these are the fingerprints of the murderer. However, this person's fingerprints are very special. There are no fingerprint features such as lines, ridges, and papillae."

"Or, the person's fingerprints may have been damaged."

"But no matter what, these two cases can be investigated together!"

Lu Chuan's discovery is extremely important.

First, from the perspective of evidence, the clues discovered by Lu Chuan completely locked the criminal suspect on the wanted fugitive.

Of course, to be more precise, it should be about fugitives, because no suspect was found in the 116 case in QZ City, so there was no such thing as wanted.

Of course, the cases are extremely important cases supervised by ministries and commissions.

In the female student dormitory, five people were accidentally killed!

What a bad nature this is!

At that time, the leaders in charge of the provincial department were in charge, and the most powerful criminal investigation experts in the province were gathered to solve the case, but there were no clues.

It is said that the president of QZ City Vocational and Technical College resigned due to this, and many students did not dare to go back to the dormitory to sleep in the middle of the night.

Public opinion about the case that year was aroused on the Internet and became very popular.

It can be imagined how great the pressure was on the office staff back then.

The most important thing is that after half a year of investigation, there is still no progress, and the case of that year can only be shelved.

Everyone did not expect that one of the murderers in this case was actually the murderer in the Qinzhou 116 case!

Second, Lu Chuan's analysis of the footprints at the scene was much more detailed than that of the Tianzhou City Criminal Investigation Detachment.

The main physical characteristics of two of the three suspects were described in detail.

This will further narrow down the scope of criminal suspects and provide greater certainty.

Another point is the fingerprint characteristics discovered by Lu Chuan.

Most people's fingerprints have features such as ridges and mastoids, and can be divided into three categories: bump-shaped, arch-shaped, and bucket-shaped.

But there are a very small number of people whose fingerprints naturally do not fall into any of these three categories.

"As for the fingerprints of suspect No. 2, I am actually more inclined to believe that the other party physically destroyed the fingerprints."

Lu Chuan made further judgment.

Oh?

Li Donglin cast a doubtful look.

"On what basis?"

"Discharge!"

Lu Chuan answered decisively.

"After I found that the traces in the kitchen of the Miemen case matched the traces on the wall of the 116 case, I conducted further analysis of the traces in the kitchen."

"Only blood remains on this mark, but no grease."

"This means that there are no oil glands on the murderer's finger. The probability of this condition being born is not high. I prefer it to be acquired."

The current investigator from the Tianzhou City Criminal Investigation Detachment nodded.

The sweat glands and sebaceous glands on your fingers are actually very developed.

Some people are born with sweaty hands, which means that their sebaceous glands and sweat glands are different from ordinary people and secrete more oil and sweat, so their palms are always moist.

But people are born without sweat glands or sebaceous glands. This situation cannot be said to be non-existent, but everyone has never heard of it.

"Xiao Lu, do you have anything else to add about Suspect No. 2?"

Lu Chuan shook his head. According to the analysis results of Lu Chuan’s investigation at the scene, the three victims were injured by three suspects respectively.

Suspect No. 1 cut the throat of the male victim, Suspect No. 2 killed the child, and Suspect No. 3 killed the female victim.

"Suspect No. 3 is a male, 1.76 to 1.79 meters tall, weighs about 100 kilograms, and is relatively fat. He is suspected to have worked as a chef for many years."

Different occupational groups, because occupational characteristics will have a certain impact on their own body shape.

Take chefs for example. Because they stand all year round, most chefs’ footprints show a regular pattern.

The angle of the feet apart is an unconscious 105 degrees. This is an acquired habit.

In addition, the left and right feet of the chef standing will have different center of gravity tendencies and will appear alternately.

The footprints left by suspect No. 3 have obvious similar characteristics.

When killing the female victim, the angle of the feet standing behind her was exactly 105 degrees, and the footprints left behind during the march showed the weight of the left and right feet changing alternately.

Of course, in addition to this, occupations such as surgeons who often work while standing also have similar characteristics.

However, the typical footprints of a doctor are different from those of a chef.

Although Lu Chuan analyzed the footprints very carefully, he was not able to draw a definite conclusion, so he used the word "suspected".

It can be said that the clues Lu Chuan obtained during this on-site investigation are very important.

With this in mind, the surveillance cameras near the victim's home can be re-examined.

Conduct focused investigations on people with similar characteristics.

After listening to Lu Chuan's analysis, everyone in the Tianzhou City Criminal Investigation Detachment became much more energetic.

They say that this is where the crime squad is so powerful.

The Tianzhou City Criminal Investigation Detachment is not saying that it is not capable, but that it really has not found any clues.

The Tianzhou City Criminal Investigation Detachment has actually made the judgment that the suspect may be a wanted fugitive.

But since he is a fugitive, he is definitely not that easy to catch.

Otherwise, if we knew where the fugitive was, we could just catch him and the original case would be solved.

Therefore, even if the Tianzhou City Criminal Investigation Detachment has this judgment, there is no way to take specific practical actions.

But it's different now. The crime team judged the approximate physical characteristics of the three suspects based on their footprints.

In this case, we can use the surveillance near the victim's home to see if we can find any traces of the three suspects.

"Are there any others?"

Lu Chuan shook his head.

He only investigated the scene for more than two hours today, and the information he obtained was limited. After all, more than half a month had passed since the incident, and many traces of the crime scene could no longer be reproduced.

Lu Chuan will next have in-depth communication with the Tianzhou City Criminal Investigation Detachment for trace inspection.

The three suspects stayed in the victim's home for a long time, and during the execution and murder, they insulted the female victim.

So did the three suspects leave any evidence in the female victim's body?

On the other hand, did the three victims leave hair or dander at the scene?

Generally speaking, the three victims will definitely leave these clues at the scene, and the Tianzhou City Criminal Investigation Detachment should not miss them.

However, there were no traces of the processing of these clues in Lu Chuan's online files.

This requires further communication with the traces here.

Li Donglin's attention turned to the Tianzhou City Criminal Investigation Detachment.
