The teacher said, "Wait a minute, Lei Zheng, you have to explain, on what basis did you rule out the love killing?" ”

Lei Zheng said: "The reason is very simple, from the perspective of the orderly dating schedule, Xiaomei's control of the three lovers is obviously relatively successful, the three lovers know each other's existence, and they do not show jealousy, the possibility of love killing is low, if a lover kills because of jealousy, then he will have some performance before killing, such as quarreling with the deceased, clashing with the other two lovers, etc., plus the deceased did not hear any movement in the deceased's house on the night of death, so I think the probability of love killing is low." ”

Li Yi said loudly: "It is also possible that the probability is low, just like someone thinks that you still have a chance to graduate, everyone says right?" I think Lei Zheng's analysis is nonsense, and the teacher will knock him down. ”

Facing the disdainful eyes of many people, Lei Zheng said indifferently: "I haven't finished my words yet, the main reason why I judged that the murderer was my brother-in-law was the knife on the deceased's head!" ”

Li Yi said: "The knife belongs to the deceased's own family, and people who often go to her house know where to put it, and the four suspects have a chance to get the knife, why do you say that the deceased's brother-in-law killed it?" ”

Lei Zheng said: "This judgment is based on the difference in the height of the deceased and the murderer, you can imagine, such a ruthless knife, it is bound to be cut down by the murderer with all his might, he will not have any cover when committing the murder, so the angle of this knife completely exposes his height, the three lovers of the deceased are relatively tall, only her brother-in-law is less than one meter six tall, everyone compares it in their hearts, and they can probably come to the same conclusion." ”

Everyone suddenly made a judgment from this point that the deceased was the same height as her brother-in-law, if the three lovers committed the crime, then the knife on the deceased's head should not break the back of the head, but the top of the head.

Li Yi said unrelentingly: "The deceased may have been picking up something on the ground with his head down or bending down at that time, and I am afraid that he would not be able to make such a sure judgment based on the angle of the knife edge alone." ”

Lei Zheng said: "This is very simple, if the deceased is killed with her head down or attacked when she bends over, then her body will not show the appearance of the crime scene, although there was no blood spurting out at that time, but the blood still immediately gushed out of the wound, you can look at the traces of blood flowing on the back of the deceased's head and neck, it is obvious that blood gushes out of the wound, first flowing downward, and then suddenly making a ninety degree turn...... This can be judged that the deceased was attacked while standing, and then fell sideways, based on the above analysis, I think the little uncle is very suspicious, of course, to confirm that he is the murderer, further investigation is needed, teacher, I am done. ”

Teacher Liu, who explained the case, applauded: "Okay, that's really good, Lei Zheng, you go down first." ”

In the sparse applause, Lei Zheng returned to his seat, and Li Yi said coldly: "Teacher, Lei Zheng may have just seen the case analysis from some way, otherwise I wouldn't believe that he would be able to say so many ways." ”

Teacher Liu said: "Li Yi, Lei Zheng may be able to see this case from some ways, then his analysis should be exactly the same as the standard answer, but Lei Zheng gave another refreshing and concise and effective analysis, I personally think it is better than the standard answer, now, let's take a look at the standard answer, let's take a comprehensive analysis to see whether Lei Zheng's answer is better or the standard answer is better......

When Mr. Liu analyzed the case, Lei Zheng still listened very carefully, he began to have some interest in solving the case, many of the fugitives from the heavenly court he wanted to arrest had a history of indiscriminate killing of innocents, and they would inevitably return to their old business of killing people when they fled to the human world.

If you want to be the first to know the news of the murder and confirm whether the deceased was killed by demons and monsters, it should be a good choice to be a criminal policeman.

Mr. Liu is talking about another way of solving the case, Lei Zheng's analysis just now is just his own experience of tens of thousands of years, Mr. Liu's comprehensive analysis has a very important enlightening effect on Lei Zheng, every idea and skill is like opening an unprecedented door for Lei Zheng, leading to a field unfamiliar to Lei Zheng, which opens Lei Zheng's brain.

The two case analysis classes seemed to pass in the blink of an eye, and Lei Zheng was completely unsatisfied, and he couldn't wait to grab Teacher Liu and listen carefully to him explain one case after another.

"When is Mr. Liu's next class?" Lei Zheng asked Yue Gangdao.

Yue Gang said with a smile: "You, if only you had been so diligent a year earlier, Teacher Liu's case analysis class is already the last two sessions, and all classes will be over before the end of this week." ”

"Ahh Lei Zheng said regretfully: "That's really a pity, is there any way to remedy it?" ”

Yue Gang said: "You can go to Teacher Liu and ask him for a copy of the courseware of his lecture, of course, you can also ask our class leader Kong Yawen, she should have a full set." ”

Lei Zheng looked at Kong Yawen's position, but saw that Yiren's curling was long gone, Lei Zheng said: "Okay, I'll ask her again when I see her tomorrow." ”

Yue Gang said in surprise: "You really plan to ask her for courseware, you, it would be good if you could do this a year or two earlier." ”

Lei Zheng said: "Yes, I want to be a criminal policeman, but if I can't finish my job, I can't be a criminal policeman?" ”

Yue Gang looked at Lei Zheng with a strange expression, this guy, he hasn't said that he wants to be a criminal policeman in the criminal police class for four years, and he actually started to think about it when he is about to graduate, the problem now is that he has failed too many courses, even if the school is willing to arrange the exam, can Lei Zheng pass the passing line?

"This ...... Maybe you should ask Teacher Xie......" Yue Gang said to Lei Zheng.

……

Xie Huiqing's office was in another teaching building, and when Lei Zheng knocked on the door, Xie Huiqing was analyzing the case materials she got at noon, and when she heard the knock on the door, she said, "Come in." ”

Lei Zheng pushed the door in, Xie Huiqing also felt impressed when he saw him, Xie Huiqing blinked, and then said, "Lei Zheng, are you here?" This looks good, sit, this is the information on the scene during the test, just two photos, but basically all the clues are reflected, you take a good look, and then go back and write a report and hand it to the squad leader tomorrow. ”

Lei Zheng took the tablet that Xie Huiqing handed him, there were two side-by-side photos on the screen, Xie Huiqing said: "You can click on one to enlarge it, and switch left and right with your hand." ”

Lei Zheng said: "Well, I will operate." ”

Xie Huiqing saw him sit down and look at the picture carefully, and he also lowered his head to carefully study the case yesterday.

Although the number of dead has reached four, there are very few clues, especially no useful surveillance video has been found, and the Wulong District Criminal Investigation Brigade in charge of this case is currently under great pressure.
