Chapter 675 Delineating the scope of criminal suspects
This is the only clue that the Beizhou City Criminal Investigation Detachment has obtained that may be pointing.
Lu Chuan has already seen it. This fingerprint is indeed blurry, making identification very difficult.
But for Lu Chuan's advanced fingerprint identification and analysis skills, it just takes more time.
Lu Chuan did not process the fingerprint immediately.
Instead, all scattered items were re-inspected.
Judging from the range of items scattered at the scene, the murderer must have gone through the victim's backpack. .
Since you have rummaged through your backpack, you may have left fingerprints, dander, and hair.
Lu Chuan wanted to conduct trace evidence analysis on these items.
See if you can find anything.
This work must be particularly tedious.
Not only were there many items left at the scene, but they also took a long time to pass.
After more than half a year of exposure to wind and sun, many traces, even if they were left at that time, have long since disappeared.
Fortunately, these backpacks are waterproof, and some of the items inside may still contain some clues.
And Lu Chuan could only complete this work by himself.
The work of the entire serious crime team entered a full-throttle rhythm just an hour after arriving at the Beizhou City Criminal Investigation Detachment.
“Our daughter is very well-behaved. She doesn’t offend people very much. She is also very popular in school and has won scholarships for four consecutive years.”
“Her boyfriend is also one of the best in the school. They are good at studying and have found a job together. This time they went to the mountains to play, and they planned to get married as soon as they got out."
"UuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuThe result..."
The group of people led by Song Mingguang began to investigate the family situation and interpersonal relationships of the four people.
"Our son doesn't have any enemies. Although his performance in school was not that good, I have never heard of any conflicts between him and his classmates."
"These classmates are pretty good in our class. Okay, there are more than 30 people in our class, and we all have a good relationship, and there are usually no conflicts.”
“We all know about the expedition last time, and there were a few other students who wanted to go, but we didn’t. They are two couples, and there is no point in us going, so let’s forget about it.”
Three days passed quickly.
Song Mingguang’s investigation did not achieve any breakthrough results or make any major progress.
The family backgrounds and interpersonal relationships of the four murdered students were relatively simple.
Judging from their own life and study trajectories, nothing suspicious was found.
I also conducted an investigation into their parents’ work and life, and found no special circumstances.
Song Mingguang is making a report in the conference room.
“My investigation results show that 4 people can basically be ruled out as being killed due to various reasons such as grudges, economic disputes, family disputes, etc.”
"So I prefer four people to explore in the mountains. It is very likely that there was a conflict with other teams or people, which led to the tragedy."
Li Donglin has been under a lot of pressure in recent days.
The news that three skeletons were found in Beiliang Mountain cannot be suppressed at all.
It has been spread a long time ago.
Now the teams exploring in the mountains have all come out one by one.
Some questions about the safety and stability of the tourism environment in Beizhou City have even begun to circulate online.
The leaders of the provincial department called Li Donglin yesterday and asked them to solve the case as soon as possible.
"Wang Song, how is your investigation going?" Over the past three days, Wang Song led a team to conduct a careful investigation of all the teams that entered the mountain at the same time as the victim's team.
“My investigation is basically completed.”
"We checked the records of expedition teams registered in and out of the mountain from the Beiliangshan Police Station."
"The registered teams were all teams led by guides. Judging from the intersection time, there were a total of 12 teams entering the mountain at that time. . ”
“Three of the teams have been wandering at the foot of the mountain, not going in depth, just for live broadcast, and there are relatively few people. Each team hired a guide.”
< br>“As for the other nine teams’ routes into the mountain, we have communicated and investigated with the guides.”
“Judging from the current situation, their routes do not intersect with those of the victim’s team. ”
"Judging from the investigation, we basically rule out the possibility that the team at the same time was the murderer."
During the investigation, Wang Song verified all members of all teams.
It is not easy to be discovered when one person lies, but it is not very likely for several people to lie together without being discovered.
Under normal circumstances, if team members collude in confessing in advance, the details and terms spoken by everyone may be relatively similar.
But Wang Song did not find this situation during his investigation.
Although everyone in the team speaks differently, the details and environment are all flawless.
“In addition, we have consulted the guides who often go in and out of Beiliang Mountain.”
“The so-called guides in Beiliang Mountain are actually some permanent residents at the foot of the mountain.”
“These residents often go to the mountains to collect herbs, mushrooms, and some mountain products, so they are familiar with the environment in the mountains.”
“But everyone’s route into the mountains is different, and the scope of picking mountain products is also different. The same, but the depth into the mountains is also different.”
"So this means that as long as most teams find different guides, the routes into the mountains will basically not be repeated."
"The guide of the victim's team took them An old hunting trail that existed decades ago.”
“According to some local guides, the mountain trail that the victims took can lead to very far areas in the mountains.”
“ And the location is very secret. If you are not a local, you basically don’t know the road.”
Li Donglin keenly captured the key points of the clues mentioned by Wang Song.
"You mean... the case was committed by local people?"
Wang Song just said that all the expedition teams that entered the mountain at the same time as the victim's team have already conducted investigations.
It has been basically determined that these teams are not suspected of committing the crime.
Then Wang Song said that the road the victim took was relatively hidden and impossible for anyone except locals to know.
There are only two types of expedition teams that do not register at the Beiliangshan Police Station.
One is to go into the mountains privately without hiring a guide.
In this case, the hidden hunting trail that the victim took was nowhere to be found.
Another way to enter the mountains without registration is for local residents.
They don’t need to register, and they know the old hunting trails.
So what Wang Song means is that the murderer is most likely a local.
Wang Song nodded heavily: "Although there is no substantial evidence to support it, based on the current situation, it is more likely that the locals committed the crime."
"So my opinion is to focus on A survey of local people near Beiliang Mountain”
