Chapter 126 Surprising Discovery
Chen Kang was slightly startled, feeding the cow?
“Why do you think of asking this?”
Lu Chuan is a current surveyor, and his family is not a professional cattle farmer. Why do you ask this?
“Did you find anything?”
Of course, Chen Kang was thinking about the investigation of the case.
“I don’t know yet, I just feel like there might be something wrong.”
Lu Chuan didn’t go into too much detail: “You ask first, and then I’ll go take a look.”
“ Okay," Chen Kang nodded and put out the butt of the cigarette that had burned to the filter: "Wait for my news."
Actually, when Lu Chuan just entered the room, it was okay to directly ask Sun Zhiyou about the situation.
But when asking about this kind of thing, even if the criminal police officer in charge is rambling sometimes, there are routines.
Whoever follows up must continue to follow up until there is a breakthrough. Unless there is absolutely no chance, or there is no inquiry effect, the person will be replaced midway.
This thing looks simple, but it is actually a psychological strategy.
Of course not everyone has studied psychology.
It is not very useful to study that thing, it is all tempered in practice.
Lu Chuan also always remembered the three things Liu Guodong told him when he came out.
Speak less, do less, and be less self-righteous.
No one can join the provincial task force.
Of course, this is not just about technology, interpersonal relationships are also part of it.
As for Lu Chuan, he obviously belongs to the technical stream.
Therefore, it is safest to use Huazi to clear the way and ask Chen Kang personally.
Sure enough, within ten minutes, Chen Kang walked out of the room again.
"Let me ask you to understand. Zhao Dong's cows need to add fodder once every morning, and usually feed water three times a day."
"Where to add fodder? Where to feed water?"
“There is a special drinking bucket for adding fodder to the fodder trough, and the water is warm, not cold.”
Lu Chuan didn't understand the details of feeding cows. He had only drank milk and never raised cows.
However, in this case, a problem arises.
Zhao Dong died for two days, why did his cows not rebel?
"Brother Chen, I have a question..."
Lu Chuan recounted what he had just seen in the cattle pen and the east wing barn.
"Two days after Zhao Dong died, a large amount of grass accumulated on the ground in the cattle pen, so that the cows had grass to eat for two days in a row."
"There are also sinks... Zhao Dong usually uses warm water. , a special bucket to feed cattle, where did this water tank come from? "
Chen Kang also understood what Lu Chuan meant: "You mean that after Zhao Dong died, there was still someone feeding his cattle?"< br>
“Or... someone put a lot of fodder and drinking water in the cattle pen after Zhao Dong died?”
“Yes, otherwise, there is no way to explain the current situation! ”
Chen Kang just thought for a moment: "Let's go and report to Li Chu."
Three minutes later, Li Donglin stood at the railing of the cattle pen in the west wing, watching the five cows grazing leisurely and gnawing ice. piece.
The ice is obviously very hard, but these cows obviously have no other choice.
You can't die of thirst, you can only eat ice.
“Any ideas?”
Li Donglin obviously asked Lu Chuan: "I can't figure out a question. If it was the murderer who did it, what was his motive?"
"But if the murderer didn't do it, who gave the cow Is there fodder in the circle?”
“Director Li, I want to conduct a detailed inspection of the two wing rooms to see if I can find anything.”
This is the same question Lu Chuan had. Li Donglin’s question.
It stands to reason that Sun Zhiyou discovered Zhao Dong’s murder this morning and called the police. That is to say, between the time when Zhao Dong was killed and when Sun Zhiyou discovered that he was killed, no one in the village should have entered Zhao Dong's yard.
Then, it seems that the fodder in the cattle pen can only be piled up by the murderer.
So, why did the murderer do this?
If it’s not the murderer, who is it?
“Okay, if you need anything, the task force will fully cooperate.”
"Yes!"
This was Lu Chuan's first time doing field survey outdoors in the ice and snow.
And the situation on site was very unsatisfactory.
The ground in the cattle pen is covered with grass, cow dung and cow urine that has frozen into yellowish brown.
Two days and two nights, five cows, God knows how much they peed.
There was no way to collect and extract the footprints, so Lu Chuan could only start elsewhere.
At this time, facing such a complex and severely damaged site, the intermediate spot survey skills gave Lu Chuan great support.
Compared to the indoor murder scene, the murderer temporarily thinks that the fodder and water were caused by the murderer.
In the cattle pen and the east wing barn, there are obviously more clues left by the murderer.
For example, the murderer must have moved the fodder from the east wing to the west wing through contact.
Another example is the two semi-cylindrical buckets, which are obviously not Zhao Dong’s original tools for drinking water for cattle.
The cutting marks on it are very new. Judging from the size and material, the murderer cut a one-meter-high plastic bucket in the corner of the east wing into two parts and then poured water into it.
In this way, the killer and the bucket have too many contact surfaces.
I have been exposed to carrying, cutting, and pouring water.
There is also a blue plastic bucket on the indoor stove, which is the only large container that can be found in the yard that can pour water.
Of course, iron basins and porcelain bowls on the dish racks can also be used, but considering the size of the white drinking bucket, the murderer is most likely to use a blue plastic bucket to hold water.
As for the faucet, Lu Chuan also wiped the fingerprint and DNA test materials several times.
Dong Zhao’s family doesn’t have running water, nor does the whole village, but they have a well they dug themselves.
A water pump was installed and a faucet was installed in the room.
With this set in place, Lu Chuan was busy until three-thirty in the afternoon.
Although I was tired and smelled like cow dung, the results were fruitful.
A large box with more than 70 evidence bags containing more than just cotton swabs, hair, etc.
Here, there is likely to be key evidence to lock down the identity of the murderer.
The technical appraisal center of the provincial department is completely different from that of the Haizhou Criminal Investigation Detachment in terms of equipment model and quality.
A lot of work does not need to be completed by Lu Chuan alone.
Most of the inspection materials collected on site are handled by specialized personnel.
Lu Chuan just needs to do his job.
This not only greatly improves work efficiency, but also specializes in the technical industry. In terms of technical testing, the provincial department has many experts in this field.
In front of the computer, Lu Chuan was dealing with five blurry and distorted fingerprints.
Yes, Lu Chuan collected five fingerprints on the two white semi-cylindrical drinking buckets in the cattle pen!
These five fingerprints are stored in different locations, but are similar in size.
Basically, it is only one-third the size of a normal fingerprint.
In addition, it is very blurry and severely distorted.
Lu Chuan initially judged that these should be fingerprints left by the same finger.
The murderer must have worn gloves when cutting the white plastic bucket, but the front end of one of his fingers should be damaged.
This caused part of the finger pad to come into direct contact with the white plastic bucket.
This left five similar one-third fingerprints.
At this moment, Lu Chuan is doing fingerprint analysis!
