Chapter 678: The Crime Team Enters the Mountain
There are two possibilities for the failure of the identification and analysis of fingerprints.
The first type is the target fingerprint obtained after fingerprint identification analysis, and its owner has not left sample information in the fingerprint database.
This situation is very common.
The police fingerprint information database must be small compared to the huge population base.
Of course, police fingerprint databases have become increasingly complete in recent years.
Especially through ID card processing, the proportion of fingerprints is increasing.
Compared with the past, now everyone who is a teenager applying for an ID card needs to have their fingerprints entered.
If this trend continues for another 30 to 50 years, it will basically be possible to cover all fingerprint records in the fingerprint database.
Of course this is just a development trend in the future.
In fact, the data in the current fingerprint database only represents a small part of the existing population.
In many cases, the fingerprints left by the murderer can be found at the crime scene.
But the murderer did not leave the target fingerprint in the fingerprint system.
In this case, the comparison will naturally not be successful.
The second possibility is that the fingerprint identification and analysis results are inaccurate. There are fingerprints of the target person in the fingerprint system, but they cannot be matched with the fingerprints found at the scene.
The second probability is also very likely to occur in actual crime solving.
Not all investigating detectives have advanced fingerprint identification and analysis skills like Lu Chuan.
Of course this situation basically does not exist here in Lu Chuan.
With his ability, after analyzing and identifying the fingerprints and failing to find the target person, there is a high probability that the target person did not leave any fingerprints in the fingerprint system.
"What do you think... about fingerprint collection?"
Li Donglin understood what Lu Chuan meant.
Since all the signs at the current crime scene indicate that the murderer may be a resident near Beiliang Mountain.
The other party left half a vague fingerprint in the deceased's backpack.
Then as long as the fingerprints of all residents near Beiliang Mountain are collected, it will be possible to successfully find the murderer.
Lu Chuan nodded affirmatively, that was indeed what he meant.
Li Donglin thought for a moment.
Beiliang Mountain is the virgin forest here in Beizhou City, with a huge area.
Not only that, Beizhou City is already the border of its own province, and after crossing Beiliang Mountain, it is another province.
The surrounding villages include those from the province, and a little further away, there are also those with another identity.
If we really want to collect fingerprints of all nearby personnel, it will involve communicating with brother units in other provinces.
In addition, if all personnel are fingerprinted, a lot of police forces will be mobilized.
This is a huge waste of manpower.
But now it involves three lives and two missing persons...
"Okay, there is no problem with this work. I will arrange it immediately. The Beizhou City Criminal Investigation Detachment will take the lead and conduct inspections of the surrounding areas. All residents will be fingerprinted."
"As for the neighboring province... I will coordinate it."
"Is there anything else you need to report?"
"Wait, Chu Li, I have one more request."
It was Lu Chuan who spoke.
“Oh? You said.”
“Into the mountains!”
Lu Chuan's request was simple and clear, with only two words.
“You want to go into the mountains?”
“Yes, although the Beizhou City Criminal Investigation Detachment has brought back all three skeletons and the photos taken at the scene are also very complete, but I I also want to go to the scene and take a look. "The most important thing is to see if we can find some clues and find some traces of the other two missing persons."
This is Lu Chuan. The most important purpose of planning to go into the mountains. There are a total of 5 people in the missing expedition team.
The bodies of three of the men were found in the same area.
As for the other two female missing persons, their bodies were not found.
Lu Chuan wanted to try it in the mountains to see if he could find anything
"In that case... no problem, we will make arrangements at the Beiliangshan Police Station to find a guide, and I will come with him, Let’s go into the mountains and have a look.”
"Yes!"
Preparing to enter Beiliangshan is not just about leaving immediately
We need to find a more experienced guide at the Beiliangshan Police Station.
Lu Chuan also needs to make some preparations.
The roads in the mountains are rugged and difficult, and a lot of equipment is difficult to bring with you.
Therefore, Lu Chuan needs to sort out his current survey equipment.
Li Donglin is also arranging other work.
So, the matter of entering the mountain had to be done early the next morning.
The Beiliangshan Police Station has special mountaineering equipment.
Because people often got lost and asked for help in the past, the police from Beiliangshan Police Station had to go in and search.
There were more cases asking for help, and gradually the equipment became complete.
Each person has a large backpack, Li Donglin, Lu Chuan, Chen Hu, deputy captain of the Beizhou Criminal Investigation Detachment, and Li Hao, director of the Beiliangshan Police Station.
A few more experienced police officers from the police station and a guide set off into the mountains.
The place where the bones were found is still some distance from the mountain entrance outside the police station.
If a few people hike into the mountain and walk inside, it will probably take a day.
This is also the main reason why the crime squad did not go directly into the mountain after arriving here.
The skeletons have been brought back, and all the evidence from the scene has been brought back. Going into the mountain is too time-consuming.
So, Li Donglin did not go directly to the crime scene at that time.
Although it is January, the weather outside the mountains is relatively cold.
But after entering the mountains, the small climate in the virgin forest begins to take effect.
Basically, every time you enter a valley and climb a mountain, the climate is completely different.
When we first entered Beiliang Mountain, there was still snow outside.
But after climbing over two mountains, the snow had disappeared.
“In our mountains, the temperature is relatively high and there is no snow all year round.”
The guide the Beiliangshan Police Station is looking for is Chen Guoshi.
Chen Guoshi is over 50 years old this year, but he has a strong body. He has been active in the mountains all year round, has strong skills and is very familiar with the conditions in the mountains.
Lu Chuan had been to Beiliang Mountain in summer, but this was his first time here in winter, and he was a little surprised by the small climate inside.
The temperature inside is not low, it feels like autumn outside.
The fallen leaves turn yellow and cover everything.
"Old Chen, are there any wild animals in the mountains?"
"There must be some, there are leopards, bears, and tigers inside."
"But the wild animals in Beiliang Mountain generally don't attack people very much. There are more wild animals here, and there is no shortage of food."< br>
“I haven’t heard of any wild animals attacking people in so many years.”
Lao Chen was quite talkative. Along the way, he introduced the specialties of the mountains to everyone, and soon we got to know each other. Everyone became familiar with each other.
Just when Lu Chuan and others entered Beiliang Mountain, the work outside was also in full swing.
Xigou Village.
"Old Song, let's take a walk. The village asked us to go to a meeting and asked us to collect fingerprints. Can we go together?"
