"And what the hell is that sour thing you just said? Why is it possible to compare with the suspect to determine whether it is the murderer? ”

"Well...... Li Heng turned his head to look around, and then whispered: "Let's go home and say this, it's inconvenient to say it here." ”

！！！

The little girl was even more confused by what her man said, what is the situation? Confidentiality is involved?

She turned her head to look at her husband beside her with some confusion, and suddenly felt like she was looking at flowers in a fog.

Back in the yard, the little couple should chat with everyone like no one else, they should wash and wash, and when they returned to the house to clean up and prepare to go to Fang's house, the little girl looked at Li Heng and waited for him to give herself an explanation.

"Hey, how can I say it, the DNA I just said is not a secret, but I don't know if we have this technology now, I do have this technology abroad, I saw it from the old leader before, but it doesn't seem to be used in criminal investigation methods, and I still do some biological research experiments in the laboratory.

What I'm talking about is just some personal speculation, and the reason why I didn't say it outside just now is because I am involved in a foreign country, and I am worried that others will hear it and cause some misunderstanding.

As for what DNA is,......"

Then he roughly popularized the meaning of this.

Unconscious, this is the real unconscious.

Although the little girl was still a little confused when she heard it, she could be regarded as solving a little doubt in her heart, and she couldn't be too careful when it came to foreign countries.

"Brother, that is to say, everything you said just now is just your own inference, and it is uncertain whether it can be realized, and besides, it is still foreign technology."

In the last few words, the little girl's voice was as small as a mosquito humming.

"Yes, but judging from what was written in the magazine I read at the time, the implementation in the laboratory is not a big problem, mainly because no one should use this as a criminal investigation method now, and of course there is another main reason in it, that is, the implementation process may require too much investment.

For example, the equipment I just mentioned that needs to be used may not be affordable by the public security system.

Our country is now poor and white, and we will not invest our limited funds in this area. ”

"Then you don't say it for a long time as if you didn't say it, it won't help my case in the slightest."

After listening to the loneliness for a long time, the little girl rolled her eyes fiercely.

"Daughter-in-law, you have to ...... Ahem, let's go, I'll help clean up the chimney in the house. ”

Fang Xiaoya glanced at it lightly, and Li Heng immediately took back what he wanted to say.

In fact, he kept thinking about this case in his heart, although he couldn't see a lot of things, but he still heard a lot of information about this case from the mouth of the little girl.

He also wondered why a seemingly simple case was so troublesome, and it couldn't be investigated.

"That's right, girl." Li Heng looked at his daughter-in-law who was combing her hair in front of the mirror and asked, "How did the deceased get into the current work unit back then, and it is also a position that requires frequent business trips, which is rare." ”

This is indeed a suspicious point, now the jobs that need to travel are basically done by men, after all, it is still more convenient for men to travel on business, and the safety factor is higher than that of women traveling alone.

"I entered the unit through normal recruitment, as for how to arrange such a job, according to the factory leader, she asked for it." Fang Xiaoya stopped what she was doing and said.

At that time, the reason she gave was that she wanted to go on a business trip to find relatives who might still be alive.

Very good, very strong reasons, of course the leaders of the factory will not refuse, anyway, as long as someone does the work.

"Does she have any close friends?"

"I didn't find that, according to the feedback of colleagues and neighbors, the deceased did not have any particularly close friends, and they were basically general friends."

Hearing this, Li Heng sighed leisurely: "Check the neighbors who live in the same yard as her, and the residents in the two courtyards adjacent to the east and west of that yard, everyone checks, check the bottom." ”

"Huh? Why? ”

"Do you have any other clues?"

"I didn't ...... Nope. ”

"Then you can only use this stupid method, and check the clues if you don't have clues. That night, the deceased was hung on the beam of his house, there must have been movement, and they lived in a courtyard and didn't hear anything, did they really sleep so dead?

There is also to send someone to Jin City to see if you can find the Yiping who was ransomed back then, the two look so similar, maybe there will be some blood relationship, maybe the deceased suddenly appeared in Sijiu City after liberation, just take advantage of this.

The person who registered her and helped her erase her previous traces was not the guest before Yiping was ransomed. Of course, there is no evidence of death now, so I don't speculate too much, but we can start from this aspect.

There must be a reason for someone who needs to erase the traces of the past. ”

Listening to her man's words, Fang Xiaoya rubbed her temples with a headache, feeling that her head was about to explode, at this moment she really wanted to leave this case alone.

"Girl, check slowly, don't worry, there will always be a day when the truth will come out, no matter who or what, as long as you have done it, there will definitely be traces left, but you haven't found that trace yet."

Li Heng walked over, put his hands on his daughter-in-law's shoulders, and gave her an encouraging look through the mirror on the wall.

The little girl leaned back like a coquette, closed her eyes slightly and hummed twice, then reopened her eyes and nodded heavily: "Knowing my brother, I will definitely try to uncover this mystery." ”

"Remember, once you find that this road is not working, take another path, and don't blindly stumble to the end."

"Well, I remember."

"Come on girl, I'm sure you'll do it."

"Hehe, thank you, brother." Probably nothing compares to the affirmation of your lover.

"MUA......" Li Heng leaned over and kissed the little girl's cheek: "Hey, daughter-in-law, how did I find out that you are very fragrant today." ”

Seeing her man's exaggerated expression through the mirror, the little girl smiled directly, raised her hand and patted the hand he put on her shoulder: "Come on, you, I've always used thousands of purples and thousands of reds, every day I smell like this, don't just say something nice." ”

"It's not good for me to praise my daughter-in-law's fragrance, you can control it."

"Poof...... Okay brother, don't tease me, let me comb my hair quickly. ”

Xiaobai on the ground had already slipped into his nest when the man and the hostess kissed him just now.

Being shown affection by these two people every day, Xiaobai feels that he is about to be depressed.
