Then use a small brush to lightly apply the powder in one direction.
The bottle is small, so you need to be very careful to smooth out the powder.
Meng Zhen held his breath and stared, afraid that breathing too hard would blow the powder away.
After a while, fingerprints on the bottle gradually emerged.
Finally, she took a small piece of transparent tape and stuck it on the surface of the medicine bottle. She pressed it hard, gently peeled it off and stuck it on a piece of white paper. The fingerprint on the bottle was completely copied onto the white paper.
After taking the fingerprints, Meng Zhen's neck and arms felt a little sore.
The national security officers watching couldn't help but exclaim, "Wow, this is amazing! They can even take fingerprints this way!"
The way he looked at Meng Zhen was as if he was looking at a god.
The people squatting on the ground also stretched their necks to look.
Hey, the fingerprints on the white paper are really clear.
The crowd immediately breathed a sigh of relief.
Oops, now that there are the spy's fingerprints, it seems that the blame will not fall on my head.
Just now they didn't dare to make a sound, for fear of being affected.
After all, those who are arrested and taken to the National Security Bureau will be skinned alive even if they don’t die!
Just like the East Factory in ancient times, they won’t stop until they have turned your entire family upside down.
Now that we have the fingerprints on the medicine bottle, it's time to collect the suspect's fingerprints.
Meng Zhen took the fingerprints of Liu Yuning and Gu Yao according to the previous method.
Then mark the collected transparent tapes with fingerprints one by one and spread them flat on the table.
Sprinkle graphite powder onto the tape and then rub the tape onto white paper.
In this way, the fingerprints of several people were all transferred to the paper, clear and clean, and very easy to identify.
Meng Zhen took out a magnifying glass and handed it to the National Security comrade: "You should do the fingerprint comparison!"
Comrade Guoan took the magnifying glass and lowered his head to compare them carefully.
While everyone was concentrating on staring at the Guoan colleague who was comparing fingerprints, in the corner, Liu Yaoguo's originally calm face suddenly turned pale.
It’s over!
What should I do now? They'll find out about me soon!
I really want to slap myself twice. How could I be so stupid as to throw the evidence into the trash can at home?!
