It's just that Li Kai, who worked with her for the first time, didn't know this, or it should be said, no one knew this, but Li Kai, who worked with her for the first time, was not very suitable for Luna's efficiency. Because most people just treat this job as a job, although they also have their own ideals and ambitions in it, few people will race against time like this after they have already caught the suspect.

Especially for Li Kai, an old criminal policeman who has worked for several years, timely relaxation and ridicule is the norm of their work, because they often have to face high-density and high-intensity work pressure, and even often face the situation of chasing the murderer for several days and nights.

"Okay, count me out for my gaffes." Li Kai shook the report in his hand.

In fact, Luna's handwriting is very neat, and there is no problem of not being able to read it at all. Li Kai understands that the reason why Luna said this is nothing more than sarcastic him, and wants to express her anger. Truth be told, there aren't many forensic doctors who can have such neat handwriting, and Luna's handwriting is just like her people, cold and hard, clean. The kind that is too clean!

"To make amends to you, I invite you to dinner." Li Kai pretended to look at his watch, "It's time to eat, let's go." ”

As soon as Li Kai's words came out, Luna's already frowning brows furrowed even tighter. She raced against time to report to help him try the case, but he actually asked her out to dinner at this time?

And Pei Jun on the side was simply dumbfounded. What's the situation? Is he, the suspect, still here? This criminal police openly picks up girls?

"Let's go!" Li Kai beckoned to Xiao Wu, and began to clean up the pile of documents and evidence on the table in the interrogation room, looking like he was about to leave.

"Humph!" Seeing Li Kai's actions, Luna snorted coldly and walked to the door first. And Li Kai also chased after putting away a few things on the table, and finally Xiao Wu, who followed Li Kai's footsteps and prepared to leave.

At this time, Pei Jun was not calm. What's the situation, these people just threw him here again?

"What do you mean? I am the informant and the first witness, and you have no right to keep me here. "The point is, he is also human, he is also hungry, he has to eat!

Li Kai, who had already walked to the door quickly, pulled the doorknob and didn't open it, and heard Pei Jun's voice turn around, "Yo, I understand a lot!" However, your current identity is not the first witness, but the first suspect. Li Kai said with a sarcastic smile, and after speaking, he opened the door of the interrogation room.

Luna was the first to rush out after the door opened, and she was too lazy to waste any more time here.

"Wait." didn't want her to take two steps out, Li Kai had already caught up and grabbed her shoulder, and forcefully prevented her from leaving.

"What else?" Luna asked impatiently as she turned around and shook off Li Kai's hand with her shoulder.

Li Kai turned around and saw that Xiao Wu, who came out at the end, had closed the door of the interrogation room, so he said to Luna: "Just now it was just to paralyze the person inside, in fact, I still have the case to discuss with you." ”

Luna raised her eyebrows suspiciously, "Can I trust you?" ”

Li Kai smiled bitterly and looked back at Xiao Wu, "Am I such an untrustworthy person?" ”

Xiao Wu, who has been working with Li Kai for more than two years, has a certain tacit understanding, almost immediately understood what Li Kai meant, so he stepped forward and took the initiative to explain to Luna: "Doctor Lu, don't worry, our Li team is already a person with a wife, and he has never touched flowers and grass, especially not eating grass by the nest." ”

"What flowers." Luna glanced at Xiao Wu before looking at Li Kai, "Say, where to discuss the case?" ”

"Go find a place to fill your stomach," Li Kai touched his already hungry stomach, "It's already past eight o'clock, and my stomach is empty." ”

To put it bluntly, aren't you going to eat? Foodie! Luna glared at Li Kai, "Let's go." ”

Li Kai nodded, made a gesture of please to Luna, and at the same time saw Xiao Wu lock the door of the interrogation room with his peripheral vision, so he was relieved to lead the two out of the door of the interrogation room.

Luna definitely didn't expect that Li Kai said that finding a place to fill his stomach would be-

Police canteen!

Luna thought it would be a roadside restaurant no matter how bad it was, right? As a result, this guy is good, even the AA system or polite words are left, and everyone takes their own work cards and swipes them directly!

"Say, what are you going to discuss?" However, at this time, Luna believed that Li Kai just wanted to discuss work with her, which also made her relax a lot, and even spoke a lot more casually, and the cold temperament that she had before that was not close to people also restrained a lot.

Li Kai tried hard to swallow a large mouthful of rice in his mouth, poured a large sip of the free tea served by the canteen, and then said, "Do you think Pei Jun is telling the truth?" ”

"Which one?" Luna raised her eyes and glanced at Li Kai, although she was also talking while eating, but her movements were obviously much more elegant, eating one bite at a time, not like Li Kai who was about to choke herself to death.

"Yes, Pei Jun said so many things, which one do you ask?" Xiao Wu, who was full of food on the side, didn't interject big or small.

"He said he doesn't remember what happened at the time of the crime, but you see, the evidence is out now, and it's almost certain that he killed his girlfriend." Li Kai quickly finished speaking with chopsticks in one hand and a bowl in the other, and after speaking, he began to take a big bite of rice into his mouth, looking like a starving ghost reincarnated.

"He didn't say he didn't remember, he said he was sleeping at the time of the crime. And repeatedly emphasized that when he woke up, the other party was already dead. Luna also knew about Bae Jun's confession, so she retorted directly.

"This is the problem, we have just compared the crime tool of the strangled deceased, and the traces on Pei Jun's hand are completely consistent with it, and it is almost certain that he is the murderer. But why did he keep insisting that he was sleeping? He doesn't know? Li Kai took another big sip of drink.

"He's lying!" Xiao Wu's rectum is authentic.

"It's easier to lie, what if he's not lying?" Li Kai put down the empty rice bowl in his hand, got up and went to the window to fill a bowl of rice and came back.

"Why do you think it's possible that he's not lying?" Luna and Wu glanced at each other, and it was Luna who finally asked.

Li Kai re-seated. He has quickly filled himself to a half-full, and he can finally analyze the case slowly and methodically while leisurely eating with vegetables.

"You see, what I said when I analyzed the evidence just now is actually not comprehensive, the traces on Pei Jun's hands are consistent with the tools of the crime, which can only show that he touched the thing before and after the crime or during the crime, and it took a lot of effort to cause strangulation marks. But in addition to the fact that he is the murderer, there are actually several other possibilities, such as that he and the murderer fought over the object before the crime, or that he tried to save the deceased after the crime and ripped the object off the other person's neck. This actually makes sense, but why didn't Pei Jun explain a word? ”

"Explain? What to explain? Xiao Wu asked dumbfounded.

"Don't you think it would be easier for him to get away if he pushed everything on a trumped-up murderer? Why didn't he try to disarm himself in this way? ”

Li Kai took another mouthful of food and put it into his mouth, "There are only two possibilities, one is that he is talking nonsense with his eyes open, he knows that he is the murderer, and he also clearly knows how Nale marks came from, as well as all the circumstances of the crime; The other is that according to him, he really didn't know anything, so he couldn't explain it at all, he didn't know how the strangulation marks on his own hands came about, he didn't know exactly how his girlfriend died, and even he didn't know what happened in those hours. ”

The scene was silent for a while, several people stopped talking, and it took a long time for Luna to take a long breath and say: "If he is really the murderer, then this person is too terrible, he can calmly call the police after killing someone, and then pretend to be innocent and cry about the death of his girlfriend, and even come back to record a statement as a witness." ”

"Yes, so, if that's the case, do you think a polygraph for someone with such psychological qualities would be useful to him?" Li Kai asked rhetorically.

"So we can't tell if he's true or not, can we?" Only then did Xiao Wu realize that the case seemed to be more complicated than he could imagine.

Li Kai nodded, "I don't rule out the possibility that he is really a calm murderer, and he will also actively investigate and collect evidence, but can we also think in the other direction to see if it is possible that he really does not have the memory of that time?" Li Kai's last words were addressed to Luna.

"It's possible!" Luna nodded, "And there are many situations that can cause this. ”

"Oh? Let's hear it. Li Kai put down the dishes and chopsticks and looked intently at Luna.

"The first is the stress response of the human body, when the person is subjected to excessive and self-unacceptable stimulation or mental trauma, the human body will seal this memory out of self-protection, which is what we call temporary amnesia, as the patient is unwilling to recall because it is difficult to accept the event, and then the emotion slowly calms down to the subject can bear it, it is possible to retrieve this part of the memory; The second is when the mentally ill patient, whether it is mania, delusion or schizophrenia, and when the disease is over, the memory at the onset is very likely to be lost, but this memory loss is not absolute; The third type is more special, it can also be regarded as a kind of mental illness, that is, double or multiple personalities, the particularity of this situation is that we can treat different personalities as different people, and when they alternate with each other, most of them do not know what the other person has done when controlling the body. ”

When it comes to psychology, Luna also puts down her chopsticks, after all, she is only a forensic doctor, although she also studied related knowledge when she was in school, such as basic psychology, criminal psychology and behavioral psychology, but she is not an expert in mental science after all. As a forensic doctor, she has the obligation to help the criminal police make technical case analysis and draw conclusions in medical and other aspects, and find that the case may have been completely or partially out of her knowledge, Luna's expression is also solemn.

"Is there a way to make a definitive identification?" Li Kai asked. Just before Luna could answer, Li Kai's phone suddenly rang.

Luna is glad that she is not eating or drinking at this time, otherwise she would have choked herself, because Li Kai's mobile phone ringtone is actually the theme song of Detective Conan, and usually after this piece of music has sounded, Conan will say seriously, "There is only one truth." Luna never imagined that Li Kai, who seemed to be quite calm, would use such a childish ringtone.

But Li Kai, who heard the ringtone, quickly picked up the phone without even looking at the number, and even Xiao Wu on the side put down the chopsticks in his hand with a solemn face. There is no other reason, just because this ringtone is specially designed by Li Kai, the phone call from the bureau will ring this ringtone, and it has been this time, if there is no matter, no one in the bureau will use the public landline to call Team Li at night.

"Hey, what's wrong?" Sure enough, Li Kai didn't ask who it was, but directly asked what happened.

"Team Li, oh no, the prisoner you left in the interrogation room is crazy!" The anxious voice of the little detective on duty came from the phone.

"Crazy? What do you mean? Be clear. ”

Li Kai said as he got up and prepared to leave, and before leaving, he didn't forget to interject to Luna, "You eat slowly first, let's go first." After speaking, he made a follow-up gesture to Xiao Wu and left.

Xiao Wu nodded apologetically to Luna, and quickly trotted all the way to keep up with Li Kai's striding meteor's back.

Luna really hasn't eaten yet, so she doesn't plan to leave the restaurant right away, but from the words Li Kai revealed just now, she still cares a lot.

Go bananas? Who's crazy? Bae Jun? And how did you go crazy? Is he really a mentally ill person? Luna continued to eat her belated dinner slowly and methodically, full of questions.
