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

Chapter 678 The Crime Team Enters the Mountain

If the fingerprint identification analysis is unsuccessful, there are two possibilities.

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 before, all teenagers who apply for ID cards now need to have their fingerprints entered.

If this trend continues for another 30 to 50 years, it will basically be possible to achieve full coverage of fingerprint records in the fingerprint database.

Of course, this is just a development trend in the future.

Lu Chuan nodded affirmatively, that was indeed what he meant.

Of course, this situation basically does not exist here in Lu Chuan.

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.

Since all the signs at the current crime scene indicate that the murderer may be a resident near Beiliang Mountain.

In addition, if all personnel are fingerprinted, a large number of police forces will be mobilized.

Not only that, Beizhou City is already the border of its own province, and after crossing Beiliang Mountain, it is another province.

Then as long as the fingerprints of all residents near Beiliang Mountain are collected, it will be possible to successfully find the murderer.

In many cases, the murderer's fingerprints can be found at the crime scene.

The surrounding villages include those from the same 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 this case, it is naturally impossible to compare successfully.

But the murderer left no target fingerprint in the fingerprint system.

Beiliang Mountain is the virgin forest here in Beizhou City, with a huge area.

The other party left half a vague fingerprint in the deceased's backpack.

In fact, the data in the current fingerprint database only represents a small part of the existing population.

Li Donglin thought for a moment.

"What do you think...doing fingerprint collection?"

With his ability, if the target person was not found after analyzing and identifying the fingerprints, it was most likely that the target person did not leave any fingerprints in the fingerprint system.

Li Donglin understood what Lu Chuan meant.

Not all investigating detectives have advanced fingerprint identification and analysis skills like Lu Chuan.

The second probability is also very likely to occur in actual crime solving.

This consumes a lot of manpower.

But now it involves three lives and two missing persons...

"Okay, there is no problem with this job. I will immediately arrange for the Beizhou City Criminal Investigation Detachment to take the lead in collecting fingerprints from all surrounding residents."

"As for the neighboring province... I will coordinate."

"Is there anything else you need to report?"

"Wait a minute, 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, I still want to take a look at the scene."

"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 the most important purpose of Lu Chuan's plan to enter the mountain. 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 missing women, their bodies were not found.

Lu Chuan wanted to try it in the mountains to see if he could find anything.

"In this case... no problem, we will make arrangements at the Beiliangshan Police Station and find a guide. I will come with you. Let's go into the mountain and have a look."

"Yes!"

Preparing to enter Beiliang Mountain is not something that can be done 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 tasks.

Therefore, the matter of entering the mountain had to be decided early the next morning.

The Beiliangshan Police Station has special mountaineering equipment.

Because people often got lost and asked for help inside, the police from Beiliangshan Police Station would 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 City Criminal Investigation Detachment, and Li Hao, director of the Beiliangshan Police Station.

With a few experienced police officers from the police station and a guide, they entered the mountain.

The place where the bones were found is still some distance from the entrance to the mountain outside the police station.

If a few people hiked into the mountain to get inside, it would 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 pulled back, and all the evidence from the scene has been brought back. Going into the mountain is too time-consuming.

Therefore, Li Donglin did not go directly to the crime scene at that time.

Although it is January now, 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.

"The temperature in our mountains is relatively high and there is no snow all year round."

The guide called by the Beiliangshan Police Station was 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, covering everything.

"Old Chen, are there any wild animals in the mountains?"

"There must be some, there are leopards, bears, and tigers in there."

"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."

"I haven't heard of any wild animals attacking people in all these years."

Lao Chen was quite talkative. Along the way, he introduced the specialties of the mountains to everyone, and he soon became familiar with everyone.

And 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?"
