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

Chapter 126 Surprise Discovery

Chen Kang was slightly taken aback, feed the cow?

"Why do you think of asking this?"

Lu Chuan is a current surveyor, and his family is not a professional cattle breeder. Why do you ask this?
"Have you found anything?"

Of course, what Chen Kang associates with is the investigation of the case.

"I don't know yet, I just feel that there may be something wrong."

Lu Chuan didn't say too much detail: "You ask first, and I'll go and have a look."

"Okay," Chen Kang nodded, and snuffed out the cigarette butt that had burned to the filter: "Wait for my news."

In fact, when Lu Chuan first entered the room, he could directly ask Sun Zhiyou about the situation.

But when asking about this kind of thing, don't look at the criminal police in charge sometimes rambling, it's all routine.

Whoever follows up must keep following up until there is a breakthrough, and will only change midway unless there is no chance at all, or there is no effect of inquiry.

This thing looks simple, but it is actually a tactical strategy.

Interpol interrogation Of course, not everyone has studied psychology.

It's not very useful to study that thing, it's all tempered in practice.

Lu Chuan also kept in mind the three points of attention that Liu Guodong explained when he came out.

Talk less, do less, and be less self-righteous.

There is not a single idiot who can enter the special case team of the provincial department.

Of course, this doesn't just refer to technology, interpersonal relationships are also part of it.

As for Lu Chuan, he obviously belongs to the technical stream.

Therefore, it is safest for Chen Kang to ask Huazi himself.

Sure enough, within 10 minutes, Chen Kang walked out of the room again.

"I understand the question. Dong Zhao's cows need to add fodder every morning, and usually water three times a day."

"Where to add grass? Where to water?"

"Forage is added to the forage trough, and there is a special drinking bucket, and the water is warm, not cold."

Lu Chuan doesn't know the details of cow feeding. He has only drank milk and never raised cows.

However, in this way, a problem arises.

Zhao Dong died for two days, why didn't his cows rebel.

"Brother Chen, I have a question..."

Lu Chuan recounted what he had just seen in the cattle pen and the warehouse in the East Wing.

"Zhao Dong died two days ago, and a lot of forage was piled up on the ground in the cow pen, which allowed the cows to eat grass for two consecutive days."

"There is also a water tank... Since Zhao Dong usually feeds cattle with warm water and a special bucket, how did this water tank come about?"

Chen Kang also understood what Lu Chuan meant: "You mean after Zhao Dong's death, there are still people feeding his cows?"

"Or... someone put a lot of fodder and drinking water in the cattle pen after Zhao Dong's death?"

"Yes, otherwise, there is no way to explain the current situation!"

Chen Kang just thought for a moment: "Go, report to Li Chu."

Three minutes later, Li Donglin stood at the railing of the cow pen in the west wing, watching the five cows grazing leisurely and eating ice.

The ice was obviously hard, but there was obviously no other way for these cows.

You can't die of thirst, you can only chew ice.

"Any ideas?"

Li Donglin was obviously asking Lu Chuan: "I don't understand a question. If the murderer did it, what was his motive?"

"But if it wasn't done by the murderer, who put the fodder in the cattle pen?"

"Director Li, I want to conduct a detailed survey of the two wing rooms to see if I can find anything."

Lu Chuan's question is also 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, no one from the village should have entered Zhao Dong's yard between Zhao Dong's murder and Sun Zhiyou's discovery of his murder.

Then, it seems that the fodder in the cattle pen can only be piled up by the murderer.

So, why did the killer do this?

If not the murderer, who would it be?
"Okay, if there is any need, the task force will fully cooperate."

"Yes!"

It was the first time for Lu Chuan to do a field survey outdoors in a world of ice and snow.

And the situation at the scene is very unsatisfactory.

The ground in the cattle pen is covered with fodder, cow dung and cow urine that has frozen into yellowish brown.

Two days and two nights, five cows, God knows how much they pissed.

There is no way to collect and extract the footprints, so Lu Chuan can only start from other places.

But at this time, in the face of such a complex and severely damaged scene, the intermediate survey skills gave Lu Chuan great support.

Compared with the indoor murder scene, the murderer, let's assume that the forage and water were all made by the murderer.

In the cattle pen and the warehouse in the east wing, there are obviously more clues left by the murderer.

For example, the fodder, the murderer must have contacted to move the fodder from the east wing to the west wing.

Another example is the two semi-cylindrical buckets, obviously not the tools Zhao Dong used to water the cattle.

The cutting marks on it are very new. Judging from the size and material, the murderer split the one-meter-high plastic bucket in the corner of the east wing into two, and then poured water on it.

In this way, there is too much contact between the killer and the bucket.

Handling, cutting, and pouring water have all been in contact.

There is also the blue plastic bucket of 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 rack are also acceptable, but considering the volume of the white drinking bucket, it is most likely that the murderer used a blue plastic bucket to hold water.

Then on the faucet, Lu Chuan repeatedly wiped his fingerprints and DNA test materials several times.

Zhaodong's family has no running water, not even the whole village, but they have their own wells.

The water pump was installed, and the taps were installed in the room.

After this set, Lu Chuan was busy until 03:30 in the afternoon.

Although we were tired and smelled like cow dung, the results were rich.

A large box, more than 70 evidence bags, which are not simply cotton swabs, hair, etc.

Here, there is likely to be key evidence to identify the murderer.

Compared with the Haizhou Criminal Investigation Detachment, the Technical Appraisal Center of the Provincial Department is not the same in terms of equipment model and quality.

There is no need for Lu Chuan to complete a lot of work alone.

Most of the inspection materials collected on site are handled by specialized personnel.

Lu Chuan just needs to do his job well.

This not only greatly improves the work efficiency, but also has a specialization 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 or one third of fuzzy 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 they are similar in size.

Basically only one-third the size of a normal fingerprint.

In addition, it is very blurry and distorted.

Lu Chuan preliminarily judged that this should be the fingerprint 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 have been damaged.

This caused part of the belly of the finger 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!
