Chapter 187

"Gulu ~" after a long time, Peng Jun came back to himself. He looked at Qin Luo and carefully swallowed his saliva.

"When you swallow saliva, your pupils dilate and your jaw protrudes slightly. The whole process lasts for one second, three times that of ordinary people. It shows that you are shocked."

"What's more, you've been stunned and haven't moved once for three minutes, which means that you've been shocked beyond the capacity of your heart."

"Well, by the way..."

"Stop it!" Before Qin Luo finished speaking, the middle-aged man interrupted Qin Luo's words with a wave.

He looked at Qin Luo seriously, the corners of his mouth twitched and asked slowly, "have you learned micro expression?"

Sorry, I didn't.

But I have a system.

The next moment, Qin Luo nodded and said with a faint smile: "yes! I taught myself! "

"Boom!" A word, like a thunderbolt from the clear sky, blew up in two people's minds, shaking their heads buzzing.

Micro expression!

The most difficult interrogation skill to learn, to learn it, you must have an experienced teacher to lead, but also rely on a lot of practical operation. By observing the expressions of various criminals, we can form a state similar to a conditioned reflex. Only in a second, or even less than a second, can we capture people's expression.

But what about Qin Luo? How old is he? 17, 18! What's more, he is still a high school student and has no access to any interrogation experts.

But at this moment, he has learned micro expression.

"Classmate, how did you learn it?" The middle-aged man, holding back his astonishment, pretended to be calm.

"Reading books is very simple."

“……”

God, I'm a little dizzy.

At this moment, he was completely confused.

Reading? Ha ha

If micro expression can be learned so easily, it will not be called the most easily failed subject by the majority of students.

"Captain, can I go down now?"

"No problem!" Peng Jun waved his hand and personally sent Qin Luo to the interrogation room.

A triangle table, one who wants to, a pair of handcuffs, and a prisoner.

This is the standard configuration of the interrogation room.

The door was pushed open, looking at Qin Luo who came in slowly, the duck cap man flashed a trace of contempt at the same time of fear.

He was afraid of Qin Luo's abnormal force, and despised that the other party sent a high school student to interrogate him.

"Classmate, don't blame me for not reminding you, you will die miserably." Without waiting for Qin Luo to speak, the other side has taken the lead in making a difficult decision.

Qin Luo:???

Hearing the man's words, he did not understand.

Where did he get his confidence?

Clearly, he is already a prisoner of the lower ranks, and has the courage to threaten Xueba.

Ha ha, it's funny

As a Xueba, Qin Luo didn't care about his threat at all. He opened the case on the desk and read it carefully.

The prisoner's name is Jiang Tuan, which was related to a robbery and homicide case in the eastern suburb of Beishan city two months ago.

The fingerprints left by Jiang Tuan were found on the victim's bag, but no weapon was found.

Not far from the scene of the murder, there was an abandoned unfinished building, which was the most likely place to discard the murder weapon. But surprisingly, after careful search, no trace of the weapon was found.

……

The following case describes the motive of Jiang Tuan's murder and the evidence that may be collected, including his family background, social relations, etc
