"Faced with problems on paper, it triggers inner turmoil, produces emotional fluctuations, and shows a sudden emotional state in handwriting."

Xun Keran's words sounded a bit awkward at first, but the old lady on the other end of the phone was obviously experienced, "Your questions on paper are related to the murder scene?" ”

Coco gestured smugly to the director, look at it, I said that other experts must understand what I mean!

The director pursed his lips and did not speak, but forced a fart sound from the leather seat to show disdain.

Coco squinted her eyes and looked at the tsundere director with disdain.

Wang Tao looked left and right, what? What did you just say? I'm the only one who doesn't understand, what?

"Who's going to explain this case to me?" Mrs. He was obviously interested.

The director looked at Coco, Coco looked at the ceiling and pretended to be stupid, and wrote 'I'm lazy' on his forehead.

The captain of the criminal police who was tired of his girlfriend had to sigh and answer the question for her, "You know the recent series of cyanide poisoning murders, each of the deceased is suspected of having sexually assaulted minors, and these former victims, or their parents, have become our suspects, but each of them has an obvious alibi at the time of the death of the corresponding target, so we suspect ...... They swap targets to kill. ”

"Hmm-" Mrs. He dragged out her tone, "so you want to try which person, which person, which deceased's death scene, wrong, and method of death have emotional fluctuations, so as to see the change in the handwriting!" That's a really interesting idea! Which of you boys came up with it? If this method really works, come to me and talk about it and write a paper! Apparently, the expert on the other end of the phone was aroused, "Who, who came up with it?" ”

Coco cleared her throat: Me.

The phone was silent for two seconds, "I remembered, you are Chang Feng's apprentice, right!" I remember you, I remember you, eh, little girl, how about coming to work in the provincial hall! Our welfare package here is much better than that of the city bureau! Much more paid time off! ”

Huh!! -- The old fox director, who had been ignored, coughed heavily. actually dug a corner in front of Lao Tzu!

"Cut," Mrs. He choked with disdain, "I'll take a look...... Well...... Change ......"

Although the words are conclusive, but Coco is actually not very sure of her own idea, she and Da Xuan designed these people who may be criminals or just victims, and let them go to the police station in different times, enter the interrogation room alone one by one to fill out the questionnaire, and the police hand them a piece of paper, so as to avoid the person who filled in the problem from being psychologically prepared, if there are really people who poison these people......

The other end of the phone seemed to hang up, silent for a while, the old fox director squinted, Da Xuan also turned to look at the whiteboard behind him, but Coco stared at the telephone motionlessly, but Wang Tao couldn't help but want to ask a question, but was stopped by Da Xuan with his eyes.

The clock moved a few squares little by little, and the telephone was still silent, and even the director couldn't help it, "Does this old woman have a bad memory and just leave us?" ”

Everyone thought they would hear a rebuttal on the other end of the phone, but no!?

Wang Tao saw that the director finally meant that someone was on his side, and he stepped forward and wanted to hang up the phone and replay it...... Coco stretched out his hand and stopped him. But he didn't do anything, just stared at the phone, as if it was going to have a miracle like a Transformer.

"Coco," Da Xuan saw the director's dissatisfied expression, and had no choice but to coordinate, "Maybe there is a phone failure, let's hang up the replay......"

"Little girl, what's your name?"

The voice finally came out on the phone, but after ten minutes of waiting, it was such a sentence, which made everyone present a little inexplicable.

Coco blinked, as if she understood something, "Xun Keran." ”

"Hmm... When this case is over, you come to me, and I want to have a good chat with you. Mrs. He's tone was different from the previous ones, with unquestionable seriousness, and even the old director didn't interrupt her. Let me ask you, on April 3, there was a courier with poison that was delivered to the Jiahe community, right? ”

Da Xuan and Coco suddenly looked at each other, "That's right, Teacher He, what do you see?" ”

"Look at Tian Hua's part, his font is too distinctive, each horizontal and vertical is almost a standard straight line, and the vertical hook is also a small diagonal line drawn with force, without traces of closing the pen. However, where is the third word 'field' in the answer to the question on April 3, the second word 'can' when answering the question of the express delivery, and the second word 'have' in answering the question that the Jiahe community has not been to that question, 'have'......"

Following Mrs. He's faster pace of speech, the people present approached the paper and looked at the words she said.

These three words, where the vertical hook is bent, the hook that should be bent inward is drawn outward, different words, different hooks, are all in the first three words of the answer question, which is for such an extreme cube of words... It's almost impossible. ”

The Director sighed and leaned back in his leather chair, "This guy is shaken. ”

Wang Tao turned around, and behind Tian Hua's name on the whiteboard, marked April 3, express delivery, Jiahe Community

Da Xuan looked a little excited, "Teacher He, do you see anything else?" ”

"Yes, Zheng Jialong has a question on a piece of paper, and the words to write the answer...... It's to ask the air conditioner outside the unit. ”

Coco pulled out the page mentioned by Mrs. He, and approached the table with Director Da Xuan like three cats and looked at it carefully, "It's nothing...... What's wrong? ”

"He didn't make a typo, you have to check the other words he answered... In this way, you take the paper and look at the light, and it is more obvious through the light... See that, right? As I just said, his words are serious, hard, and conservative, and on this page, the writing force is particularly light, so light that the horizontal and vertical of the first dozen words are unstable, and it is only after the last few words that he regains his strength. ”

Da Xuan frowned slightly, "Teacher He, are you sure this can show his weakness?" ”

"Boy, the strength of handwriting is a very obvious feature, just like when you hear something very frightening, your hands will suddenly be unstable is the same reason, people's limb coordination comes from the brain, the brain gives instructions to the limbs is easy to be affected by emotions, if you are pressing the huge fluctuations in your heart, hand tremors, cold hands and feet are very common reactions, the power of writing suddenly changes, he is already well hidden, so speaking, where do you let them write the answer? If you have the surveillance video at the time, you can further study the situation in detail, and if you are worried that it will not be enough to convince the prosecutor there, take the video, and I will help you find an expert who analyzes micro-expressions and body expressions to see. ”

"Oh, Mrs. He, why are you suddenly so positive?" The director laughed.

"Hmph, of course I'm not here for you. What about the little girl? ”

"I'm here."

The other end of the phone groaned for a while, as if thinking about how to express it, "I now understand why Chang Feng, who has always been patriarchal, chose you as a closed disciple." ”
