Chen Mo saw Ye Zi who was covering his face with his backpack at a glance, he pressed his eyebrows slightly, stepped forward, grabbed the collar of Ye Zi's coat, and directly picked her up as if he was carrying a little chicken.

"Oops, oops, ......"

Ye Zi slapped Chen Mo's hand vigorously and complained: "Please, Brother Chen Mo, in front of the public, can you give me some face." ”

"Do you still want to save face?" Chen Mo raised his eyebrows slightly, his face was gloomy like ash at the bottom of the pot.

Ye Zi pursed her lips, "Why don't I lose face!?" ”

Chen Mo's sparse and sharp gaze swept over Ye Zi's body, and at a glance he saw the police officer in Ye Zi's hand, on the card, seeing this, his face sank again, and asked in a cold voice: "Are you pretending to be a police officer to investigate the case again?" ”

"Nope!" Ye Zi hurriedly waved her hand, "I'm a good citizen, how can I pretend to be a policeman." ”

Chen Mo raised his hand, pointed at Ye Zi, and said in a deep voice: "You, you are always so disobedient, you are stepping on the line, sooner or later something will happen." ”

Ye Zi stuck out her tongue at Chen Mo, smiled, and said, "As long as you are here, you will never let me ......"

Before Ye Zi's words were finished, Chen Mo suddenly raised his hand and shivered on her forehead.

"Oops!" Ye Zi exclaimed, raised his hand and touched his forehead, "Brother Chen Mo, it hurts." ”

"It's good to know that it hurts, I thought you weren't afraid of heaven and earth." Chen Mo shook his head helplessly, and then, he turned around and glanced at his Beijing Jeep, his thin lips opened slightly, and he said in a deep voice: "Get in the car, I have something to tell you." ”

Ye Zi pursed her lips, drooped her head, and followed Chen Mo into the car.

Chen Mo had a gloomy face, glanced at Ye Zi with a cold gaze, and changed his gaze to a soft gaze, he shook his head helplessly, and said in a deep voice: "Little girl, let's say, what did you ask?" ”

Ye Zi didn't dare to hide anything anymore, so she had to tell Chen Mo about the conversation she had just had with the kindergarten teacher.

"Oh?!" When Chen Mo heard this, his face suddenly darkened, he was silent for a moment, and then he raised his eyes to look at Ye Zi, and asked in a deep voice: "Little girl, what do you think about this?" ”

Ye Zi pondered for a while, her hands seemed to be unintentionally fiddling with her clothes, and after a while, she spoke: "I think we should be the first to find the man who had a dispute with Zhou Jie now, and then ......."

Before Ye Zi's words were finished, Chen Mo suddenly raised his hand, interrupted Ye Zi's words, and said in a deep voice: "It's me, not us." ”

Ye Zi pursed her lips, "What's the difference?" Brother Chen Mo, this case involves me, do you think I can not investigate? ”

Although he said so on his lips, Ye Zi thought of the mysterious person in his heart, there are still two days to go, if the real murderer is not found within these two days, I am afraid that it will ...... The woman's life......

Ye Zi didn't dare to continue thinking about it, and pondered for a moment before saying, "Brother Chen Mo, I promise you, I won't cause you trouble, and I won't involve the police, can't I investigate it myself?" ”

Chen Mo shook his head and said in a low voice: "Little girl, you also know that the murderer this time is not a good stubble, we now suspect that this person has a psychological problem, through my profile......"

"Brother Chen Mo, do you want to hear my profile?" Ye Zi suddenly interrupted Chen Mo's words and said, "Don't forget, I'm my father's apprentice, my profile is definitely not worse than yours." ”

Hearing this, Chen Mo fell into deep thought.

I have to say that Ye Zi has indeed obtained the true biography of the master, in terms of criminal psychology profiling and interrogation, Ye Zi is indeed much more powerful than many, many criminal policemen, if it is not for the master who does not allow Ye Zi to apply for the police academy, I am afraid that Ye Zi is already an outstanding criminal policeman now.

Ye Zi saw that Chen Mo was not talking, she leaned towards Chen Mo, smiled, and said: "Judging from the on-site investigation, I can come to a conclusion that the murderer has a certain revenge mentality, Zhang Ran and Zhou Jie are both young people, and they are in good health, and the two of them were not drugged and stunned by the murderer before they died, which is enough to show that the murderer's physical fitness should be above Zhang Ran and Zhou Jie." ”

Chen Mo also knew this, he raised his eyebrows slightly, and said to Ye Zi, "You go on." ”

The corners of Ye Zi's mouth curved slightly, evoking a shallow smile, and then, Ye Zi continued: "To be able to complete such a complicated murder procedure, the age of this murderer should be between 25-35 years old. ”

Chen Mo nodded, "At this point, our police have also determined the result." ”

Ye Zi: "And this murderer didn't even let go of a child, which can show the murderous nature of the murderer, so I think this murderer must have a mental illness." ”

"You mean perverted?" Chen Mo frowned and asked.

Ye Zi shook her head slightly, "It's a mental illness, such as: depression, mania, etc., it's just that the murderer should have other mental illnesses, as for what type it is, you still need to find a psychiatrist to ask." ”

Chen Mo did not think about this, he once contacted the psychiatrist of the police force and learned that the murderer may have a serious mental illness - two-way depression.

Depression in both directions.

Depression is an affective mental disorder that can be divided into two categories in terms of characteristics: one is uniphasic, called "depression". Every time I do it, I feel depressed. The other type is called "bipolar" and the full name is "manic-depressive disorder". A few times I was depressed, and on other occasions I was overexcited, and I couldn't even control myself, and I was in a manic state.

Commonality with common depression: they are both adherent mental illnesses. Usually each work lasts for a few days, and some can last for months. Generally, after a period of work, it will be relieved by itself, and the remission period will completely return to normal, and I can fully know the abnormality of the work, and I hope that it will never be repeated, but it is often done many times, which is beyond the control of the patient.

From the fact that the murderer wiped the entire house with blood after killing Zhang Ran's family of three, it can be seen that before the killing, the murderer was violent, and after killing people, he was depressed.

"There's one thing you shouldn't have thought of." Ye Zi suddenly spoke, interrupting Chen Mo's thoughts.

Chen Mo frowned and asked suspiciously, "What!?" ”

Ye Zi lowered his voice and said word by word: "He should also be a parent, maybe a father." ”

"That's why you're coming to the kindergarten to investigate?" Chen Mo looked at Ye Zi for a moment.

Ye Zi nodded noncommittally, "That's right." I heard Mr. Li say it just now, that's why I want to find that man. ”

"You mean that the man might be the murderer?" Chen Mo stared.

Ye Zi chin slightly, red lips opened slightly, and said in a low voice: "Perhaps, I should have seen this man." ”

"Have you seen him?" Chen Mo twisted his eyebrows into a twisted shape, staring at Ye Zi for a moment.

Ye Zi nodded and said: "When I left from the scene of the murder, I once saw a man, at that time, everyone was watching the excitement in the direction of Zhang Ran's house, but it was only him, turned around and left, I followed him for a while, but he still ran away." ”

Chen Mo's face was solemn, and after muttering for a long time, he lowered his voice and said, "Little girl, this person is very dangerous, so you can't interfere anymore and hand it over to the police for investigation."
