An hour and a half later, the polygraph ended, and Qiu Jinghao pushed the door out.

Officer Cao hurriedly greeted him and asked, "How is it?"

Qiu Jing shook her head lightly, and Officer Cao wrinkled her eyebrows, "Isn't it?"

"Hmm. Qiu Jinghao said, "Go to your office." ”

"Good. Officer Cao walked in the direction of the office with a serious face.

When she came to the office, Officer Cao covered her face, poured a glass of water and handed it to Qiu Jinghao, she politely took it, "Thank you." ”

"Qiu Tesuke, can you really be sure it's not him?"

"Definitely, he didn't do it. ”

"So," Officer Cao pondered, "What is the accuracy rate of polygraphs?"

Facing his questioning, Qiu Jinghao lightly pushed down the frame, "Officer Cao, the accuracy of my polygraph is several times that of a polygraph after the F test. ”

She said it lightly, but with a majestic seriousness.

Officer Cao was also anxious, and he was a little speechless, so he immediately apologized, "I'm sorry, I also want to catch the murderer as soon as possible." ”

Qiu Jing was neither happy nor angry, but still calm and calm, "I understand, but he is really not a murderer." You've mistaken it. ”

Her determined tone made Officer Cao feel more and more impatient, and he raised his head and said, "But it's not him, who is it?" On the day of the fifth deceased, he was one kilometer away, covered with the blood of the deceased, and his footprints were all around the deceased. All this evidence points to Feng Hongyi. ”

"You're wrong!" Qiu Jinghao spread out the notebook in his hand, put it on the table, and pointed to a line of words: stuttering

Officer Cao was puzzled, "What does this mean?"

Qiu Jinghao opened the file, and the murder cases of the five cases were spread on the table, and her eyes fell, "Officer Cao, according to my profile, the murderer is a criminal with a hidden disease, and my judgment is that he suffers from a severe stutter. ”

"Suffering from stuttering?"

"Yes. ”

"How did you deduce that?"

Officer Cao obviously doubted Qiu Jing's good reasoning, although she was a talent in the field of polygraphy, but in the actual solving of the case, he felt that her judgment was debatable, and he did not agree with the characteristics of the murderer just by looking at the scene.

Qiu Jing is used to the suspicious eyes of others, she doesn't need to force anyone to believe, she just needs to do a good job, be herself, and complete SE.

There is a good saying: facts speak louder than words!

She said calmly: "In these five cases, he chose to commit the crime behind his back, which is very suspicious." The five dead, unarmed and without any signs of a fight, were all fatally shot by a single shot. Then if he does this, he must have the concern that he doesn't want to be seen by the dead, and he must use sneak attack methods to kill with one blow. Shot in the back, the killer was hiding and confronting the deceased head-on. And you can clearly see the characteristics of revenge! Strike ruthlessly, kill with one shot, he doesn't want to give the other party a way to live, he just wants them to die. What is the reason for the murderer to vent his inner anger by putting the other party to death?

My judgment is that the murderer had a hidden disease of stuttering.

So why do I judge it to be a stutter instead of going to his question?

First of all, I will rule out the problem of intelligence first. A murderer with intellectual defects will not create an orderly crime scene, nor will he clean up the scene so cleanly, so I ruled out mental retardation.

The second is the appearance defect, according to your visit records, there are no suspicious strangers found in the town of Lorraine, and the environment here is cramped, there is only one road through the town, and the road is far away, drivers will choose to settle here to refuel, Accommodation, etc., but your records indicate that there are no people with special appearances, and everyone is curious, for example, when you see people with extremely special appearances, they will leave a deep impression and will reveal them when you visit, but you do not get such information. Foreign trade defects are excluded.

Third, if the murderer does not have obvious physical defects, then he must have an internal hidden disease. There are roughly five types of hidden diseases of people, eyes, nose, mouth, ears, and sexual function!

If the opponent is blind, then accurate shooting will not be possible. The problem of smell is not enough for people to know and laugh at, and the deaf person cannot hear the sarcasm and ridicule of others, so there is no chance of violent conflict or hatred.

The rest is also the mouth and sexual function.

The five deceased were male, and they were sturdy and handsome, and all five of them had a history of marriage, so they were not closets, and if the murderer was really the same person, he would not have the urge to kill the person he met for the first time. In other words, if he doesn't do it, he won't want to do it, so how can he be angry and want to shā rén when he can't ask for it?

In the end, the mouth remains. People who suffer from stuttering can easily be noticed and ridiculed by the other person once they speak. And this hidden disease must have been with the murderer for a long time, and the perennial ridicule caused the murderer's heart to be depressed, and when people's emotions were suppressed to the point that they could not be resolved, it would explode, then the case happened a month ago, so the murderer must have been completely enraged a month ago. He began to punish those who mocked him in the manner of shā rén. ”

After Qiu Jing finished speaking, she glanced at the disposable water cup on the table, swallowed, but did not take it.

Cleanliness is not shallow.

And after listening to Qiu Jing's long list of analyses, Officer Cao nodded heavily, as if remembering something, he got up abruptly and exclaimed:

"It's him!"

Qiu Jing looked at him calmly, her eyes were asking, who is it?

"When Xiao Chen and I went to visit, one of the lumberjacks had a stutter. ”

Qiu Jing bowed slightly, it should be him.

Loggers often huó dòng in the mountains and forests, and the ecological protection of this area is very good, and there are often incidents of wild boars and black bears attacking people when logging, so for safety reasons, some loggers will carry liè qiāng with them when they go to the mountains and forests. Although this is regulated, it is inevitable that some people make their own liè qiāng or buy it privately.

Officer Cao looked at his watch, "There is less than an hour before the coercive measures, Xiao Chen and I went to find the lumberjack and brought it back for a monitoring of the residue of huǒ yào, as well as a comparison of ballistic traces, once it is confirmed that it is him, Feng Hongyi can be released immediately." ”

Qiu Jing closed her notebook and stood up slowly, "Since you have a goal, I won't delay your case." If necessary, Officer Cao can call diàn huà. See you soon!"

Officer Cao was eager to handle the case, after all, a thug who carried five lives was outside, this was not a joke, after he sent Qiu Jing away, he immediately rushed to the town of Lorraine with Officer Chen.

When he returned to the office, Ah Qi was waiting at the door, and Qiu Jing walked up, "Why didn't you go in?"

Ah Qibi replied respectfully, "Young grandmother, Madame is here." ”

Madame?Qiu Jing's blank eyes flashed, but she quickly remembered that Mu Ziqian's stepmother, Aunt Hui.

She nodded faintly, "Okay, I see." ”

Qiu Jing was just about to open the door, but Ah Qi stopped her, "Young grandma, I have already informed Mr. Mu, why don't you go in later?"

"Why are you waiting for him to come?" Qiu Jing said a good word, leaving Ah Qi speechless, she continued: "Tell Ziqian, don't use it, it's nothing." ”

Ah Qi hesitated, Qiu Jinghao knew that he was also worried about himself, so he took out shǒu jī and called Mu Ziqian to diàn huà.

At that time, the quarterly Xiāo Shòu report meeting was being held in the Mu Group, and Mu Ziqian sat in the main seat, listening to the data reported by various departments, while also flipping through the report, his cold face, without a trace of expression, obsidian-like pupils, and a quick glance of ten lines.

Now is the return stage of the finance department, which is also the heart department of the entire group, and he cannot leave halfway for the time being.

But after receiving Ah Qi's diàn huà, he was very worried that Aunt Hui would not be good for Qiu Jing, so when he read the report, he was inevitably distracted.

The moment the diàn huà sounded, his heart tightened, and when he saw the shǒu jī number of Qiu Jinghao, he picked it up even more uneasily.

"Wife" His voice was tense and cautious, as if he was listening to her voice, testing her tone and attitude to determine if something was wrong.

Qiu Jing knew it as soon as she heard it, and a faint smile appeared at the corner of her mouth, but this light smile was quickly put away.

"Ziqian, you don't have to come over. ”

"What's the matter?"

Qiu Jing looked at the closed door, "Not yet." I'll call you diàn huà, just to reassure you, Aunt Hui is an elder after all, what can you do to me, you don't have to be too nervous, and there is Ah Qi here, you can work with peace of mind. ”

When Mu Ziqian hesitated, he said again, "It's nothing, hang up." ”

"Wait!" Mu Ziqian hurriedly stopped people.

The microphone was quiet, just like the feeling she gave him, the years were calm, and he was quiet.

"Wife, what Aunt Hui says, you don't have to care, I am in charge of this family!"

Qiu Jing said lightly: "Got it." ”

"If there's anything that can't be solved, call me diàn huà. ”

"No, I'm not as weak as you think. ”

"Good. I'll call you diàn huà after the meeting. ”

"You're busy, goodbye. ”

Hanging up diàn huà, Qiu Jinghao put shǒu jī in his pocket, pushed open the office door and walked in.

At that time, Aunt Hui, who was sitting on the sofa, frowned tightly, with an impatient expression, and saw Qiu Jinghao walk in, and put out her eldest wife's shelf.

"Why did you come back?" said Aunt Hui.

When Qiu Jinghao came in, she didn't let Ah Qi in, looked at him, and asked him to stay outside the door.

She closed the door, walked and poured a cup of tea, and brought it to Aunt Hui.

"Aunt Hui, I'm sorry, I didn't know you were coming, I kept you waiting, let's drink tea first. Qiu Jinghao was holding a teacup in her hand, while Aunt Hui, who was sitting on the sofa, only looked at it coldly, but she didn't answer it for a long time.

Qiu Jinghao directly put the cup on the coffee table in her hand, "There was a case just now that I needed a favor, so it was delayed for some time." ”

Aunt Hui looked her up and down, frowning brows, disgusted eyes, her legs folded, her elbows propped on the armrests of the sofa, and said in a disdainful tone:

"A woman who is a wife, who is not at home with her husband and children, comes out and doesn't say anything, and does such an unlucky job, I don't know what Ziqian thinks, I'm really used to you, let you do nonsense!"

Qiu Jinghao raised her head slowly, "Aunt Hui, in your eyes, the only thing a woman can do is to teach her husband and children?"
