Chapter 446 Check fingerprints to check the owner of the cigarette box

Gu Yuehuan interrupted Jiang Yin'er's self-talk, "Don't worry, I have nothing to do with him, he is from our school and my brother, so I came to ask him for help, and what I want, you can go to the school to inquire , You can also ask. I definitely did not bribe him, I swear, if I did, I would be struck by lightning! He learned this kind of knowledge, and he is well-known in his profession."

"Besides, Miss Jiang, if I remember correctly, you are a medical student, and you have also studied abroad, and you have been influenced by foreign cultures, so how could you not know that there is such a thing as fingerprint extraction? Miss Jiang, you Is your diploma a fake? I can’t believe it’s coming out of a doctor’s mouth.”

Jiang Yin'er was a little embarrassed when she heard this, she wanted to get mad, it was obvious that this woman had intentionally hurt her, and she was afraid that it would be bad if she got mad.

She didn't know what to say, Gu Yuehuan said to the old lady: "Grandma, if you don't believe me, you can go and investigate. I am absolutely innocent and have nothing to do with him. I just know each other and have not violated the rules. Besides, grandma, I Everyone doesn’t know what I said now, but when he finds out later, he will know what I mean.”

The old lady couldn't do anything after hearing this, so she let them do it.

Jiang Yin'er was worried and didn't know what to do. Jiang Dahe is definitely a genius in this area, and has been studying these things.

He just felt that no one could understand what these things he was researching, until Gu Yuehuan appeared, and he discovered that there was someone who was so compatible with her.

He went over now, and he took out some chemical reagents, which he took out in the school laboratory.

He took these things out and put them on the table, put on a glove, and took the cigarette box over.

Cigarette boxes have already been touched by many people during transportation, so there is no need to check many fingerprints, only the layer of fingerprints covered on the top, and he extracted a few obvious fingerprints , put it on the paper, and the transparent liquid is sprinkled in, so it appears fluorescent.

After he extracted it, he showed it to the old lady and them, "It's just a few fingerprints I extracted on the cigarette box, you can take a look, these are the most obvious fingerprints on it, only the fingerprints that have been exposed recently Stay on the top, the fingerprints of the recent contact with the cigarette box are all here, so the owner of the cigarette box can check it out."

The old lady was taken aback when she saw this operation, not knowing what was going on.

But it is obvious that there are really several fingerprints on it.

She saw the fingerprints and asked a little excitedly: "So next, what should I do next, can it really be found out who these fingerprints belong to?"

Jiang Dahe glanced at Jiang Yin'er and said, "It's ok. Next, please reach out and show me your fingerprints. I'll apply something on your hands and extract your fingerprints. I'll compare them later." It's obvious who has fingerprints here."

Jiang Yin'er couldn't see her face when she saw him extracting the fingerprints on the cigarette pack just now, but now she heard what he said, and she was even more frightened.

He...it's real, able to extract hand prints.

If he grabbed his hand to extract it later, wouldn't it be completely exposed?

Jiang Yin'er was so frightened that her face froze.
