This cop is a bit wild

Chapter 40 Sister, I want to borrow your ancestral DNA for use
Director Long nodded in approval, and then asked: "Is there any more?"

Team Wu immediately said again: "Yes, we have arranged for personnel to inquire about the relatives and friends of the deceased, mainly to find out the relationship network of the deceased before his death, and to see if he had any love or hatred with others."

Director Long said solemnly: "You should think more thoughtfully, consider all kinds of situations, think deeply about the problem, and do a solid job. Don't fail at the end and start the reconnaissance at the beginning again. Various reasons were found in the process.”

"understand!"

Afterwards, Director Yang made another statement, which roughly meant to overcome difficulties, carry forward the tradition of "homicide cases must be solved", and solve the case as quickly as possible.

After the meeting, Director Long went to the various investigation teams to check and visit. One was to supervise the work, and at the same time, it was also a condolence to the front-line investigators.

Walking down in a circle, Long Ju just returned to the city.

Leaving Yang Ju and others to continue fighting on the front line.

At this time, the comrades in the video surveillance team had already run through the entire highways of Gaoyang County, as long as they could pass by motorcycles, and marked all the surveillance along the way. All of them have been retrieved.

The investigators of another relationship sorting team also completed the inquiry of the relatives and friends of the deceased, and mastered a relationship network of the deceased before his death.

Humans, as long as they live in this world, there must be some grievances and hatreds.

Normally, these grievances and grievances are nothing but talk before tea and after dinner, even if I think of it occasionally, I may just laugh it off.

But once a murder case is encountered, any clues will be dug out.

Even the embarrassing thing of whether he had found a lover before his death would be found out.

After all, there is no impenetrable wall in the world. As long as two people know about anything, it is not a secret. Now that people have died, who would dare to hide it?

However, the relationship between Jiang Jing, the deceased in this case, was not very complicated, and she belonged to a typical rural woman.

When I was young, I worked with my husband in a coastal city. In the first two years, because I had a grandson, I went home to help raise my grandson. I did some farm work in my spare time. My life was peaceful and peaceful.

Of course, disputes also exist, such as conflicts between neighbors over the boundary delineation of field ridges.

Another example is that it is normal to chew people's tongues behind their backs and arouse resentment.

As for whether this kind of resentment will make people fight with their lives, it varies from person to person.

In addition to these, the police also focused on investigating her whereabouts yesterday.

Yesterday morning, she took her grandson to the town to go to the market. After returning, she had lunch and then went to work in the crop field.

Then there was the unexpected disaster.

Judging from the information currently available, the possibility of love and vendetta murders in this case is low, but apart from love and vendetta killings, there are only impromptu murders, such as robbery and rape.

But the police also have doubts about this.

Rape and homicide can be ruled out, and robbery and homicide are equally unlikely.

Why would a person who wanted to rob a robbery place it in the countryside?Wouldn't it be nice to find rich people directly in the city?

So, this matter is still a mystery.

Fortunately, the police do not rely on logical reasoning to handle cases.

Watching the monitor directly, what you see is what you get, that's great.

There are indeed very few surveillance cameras around the crime scene, but basically there are surveillance cameras at the main intersections of each village. Although these surveillance cameras are not well maintained due to various reasons such as funds, and there are always some faults of one kind or another, but only relying on those who are still alive It is still no problem to draw a sealing circle one by one.

Even if the circle is a bit big, it is better than a net full of loopholes.

In the blink of an eye, it was late at night.

Although the case is serious, the police often use day and night fighting to express the importance they attach to the case, but in fact they still have to sleep.

Humans are not machines, so how can they not sleep?
Maybe it is acceptable to stay up late for a day or two until there is a major breakthrough and you need to rush for time.

……

When the Criminal University and the Gaoyang Institute were having a headache about the 8.23 ​​intentional homicide case, Dong Ze was also having a headache.

How can we find out what happened to Feng Ying?
The easiest way is Yuri's mind control, but unfortunately God didn't favor me, so I didn't get that skill.

Can only go the usual way.

Dong Ze first made an assumption in his heart, assuming that Feng Ying did have a problem.

In this way, she has been cautious all these years and dare not use her ID card, most likely because she is worried that she will be exposed.

If she really thought that what she committed was hidden from anyone's knowledge, she shouldn't have such anxiety, then she should have left some evidence, at least she thought she had left some evidence at the time.

If the police have some identity-oriented evidence, there is no reason why they cannot find out her identity, so that she is not present among the fugitives.

What kind of evidence can prevent the police from being able to connect with its identity?
As a police student, Dong Ze's first reaction was DNA and fingerprints.

Regardless of the former or the latter, the police have not yet achieved universal coverage.

Not to mention the former, except for those suspected of breaking the law, it is impossible for the police to collect blood samples on a large scale.

However, in many illegal and criminal processes, the possibility of leaving biological samples is very high.

But how did Dong Ze prove this?Do you want to run up to the other party and say: Sister, I want to borrow your ancestral DNA for use?

It's easy to get beaten that way.

The other is fingerprints.

Compared with DNA, the sampling rate of fingerprints is much higher. As long as it is a new ID card, fingerprints will be collected once.

in case……

Suddenly, Dong Ze's heart skipped a beat.

He thought of the characteristics of Feng Ying's activities that he had found on the internal platform.

At the beginning, she used her ID card quite frequently, but later it became less, and more than two years ago, she stopped using it directly.

Why is it not used at all?

Dong Ze felt that the possibility of loss was relatively high.

If a normal person loses his ID card, he will immediately go to the household registration window of the police to reissue it.

However, the reissue of an ID card required fingerprinting, so Feng Ying dared not go.

This will explain why she has not used her ID card.

The more Dong Ze thinks about this possibility, the more excited he becomes.

If the other party's fingerprints can be collected, will the truth be revealed?
But how can we collect each other's fingerprints?Neither Feng Ying's place of residence nor her place of work is within the jurisdiction of the Xicheng Police Station, and she cannot urge the massage parlor to require its employees to register at the police station on the grounds of inspection.

The point is that such urging is unreasonable.

Suddenly, a thought popped out of Dong Ze's mind, and a smile appeared on his face.

That's it!

Sleep and sleep, the dog's life matters.

……

The first ray of sunlight in the morning squeezed in through the cracks in the curtains, and shone coquettishly on Dong Ze's face.

He opened his eyes, and glanced at the curtains that could not be completely closed due to long-term use with some disgust.

"I changed you back!"

After spending 3 minutes washing up, Dong Ze summoned lightning and walked out of the house.

On the way, Dong Ze called Wang Tiezhu.

When he learned that the other party was still busy, he didn't ask any more questions. He believed that once Wang Tiezhu and Wang Tiezhu found the target, they would definitely notify him as soon as possible.

After a breakfast in the cafeteria, a new day of work started happily.

Dong Ze's task today is very easy. He followed Fang Ziping to complete the safety inspection of all special industries in the jurisdiction.

This kind of security check is monotonous and complicated, but it has to be done.

Compared with checking road traffic safety last weekend, Dong Ze prefers this kind of inspection.

After all, the people who were in charge of reception in these inspected units smiled brightly and spoke nicely.

The most important thing is that even if I ask some strange questions, the other party will enthusiastically answer them one by one.

In this state, the experience value of "Words and Moods" will naturally soar, and it will be more exciting than during the on-duty period, and the mentality will be more relaxed.

Apart from returning to the institute for a meal at noon, they wandered around the jurisdiction all day.

When he was about to get off work at night, Fang Ziping felt the weight of his legs filled with lead, and looking at Dong Ze's eagerness to try, he always felt that his energy was more vigorous than the lively lightning next to him.

"Xiao Dong, I'm off work and I'll continue tomorrow."

Dong Ze looked left and right with a lot of interest: "There are only two units left in this street that have not been inspected, or..."

"It is said that there are steamed pork ribs in the cafeteria at night."

"Uh, let's go back! It is estimated that the inspected unit will also get off work." Dong Ze said solemnly.

Fang Ziping's fat face smiled like a flower.

Back at the institute, it was confirmed that Fang Ziping had not lied, and that the hard dish in the cafeteria was indeed steamed pork ribs.

But Fang Ziping himself complained about it. The steamed pork ribs that he promised were mostly pork spines. Although they were cut into small pieces, they were still spines, right?

Dong Ze was very satisfied with this.

After eating, Dong Ze returned to the office, picked up his teacup, quietly got some wolfberries from Fu Li's drawer, poured half a cup of boiling water, and left the police station leisurely.
