As for the cause of death, I still set it as an electric shock, this current spot is very typical, there will be no problems, the laboratory work of blood and stomach contents is routinely handed over to Wu Haoyu, regardless of whether there is poison or not, this exclusion work is necessary.

I returned to the scene and began to investigate, Guo Weitian was using electrostatic adsorption to absorb shoe prints, I didn't bother him, I walked around the spacious warehouse by myself. It's a big place, with worn-out books piled up here and there, and some expired newspapers, and I looked through the records of the sale of waste paper, and every Saturday there was a record of a different weight, but the day before yesterday there was no record on this Saturday. If you can find the vendor who recycles used books, you may be able to understand why he didn't come to buy the scrap newspapers that day, which he should have done every Saturday.

I suddenly thought about it, why didn't he come to buy it that day? Is it just a coincidence? On the day he didn't come, there happened to be another murder here, is there any correlation between the two events? In a homicide scene, there are often some abnormal situations, these abnormal situations are often the breakthrough in the investigation of the case, but sometimes it is not necessarily, the scene that looks normal will also let an experienced on-site technician see the problem, such as today's corpse, it did not escape from my eyes, on the surface everything seems to be normal, but it is a fake murder scene.

Normal and abnormal in the eyes of different people, its meaning is not the same, the so-called not according to the routine of the card, is this reason, according to the routine of the cards are low hands, not according to the routine of the card is the master, but this case for me, is just a basic skill, I never felt that I was a master.

I saw a bunch of books next to the table, the top one is "Introduction to Forensic Science", a very familiar word, so I went over and flipped through it, if in normal times, I would definitely think that this Chinese student Wan Shaoming is going to create forensic science-related literary works, but today, I suddenly realized that he may have read this book in preparation for crime!

In order to achieve the purpose of killing people and changing clothes, Wan Shaoming clearly learned professional knowledge, but everything he planned still lost to the professional, and he didn't know that it was anthropological knowledge that knocked him down.

The corpse turned out to be lying on a single folding bed, which was usually where Wan Shaoming took a lunch break. The wire used during the electric shock was still at the scene, and I saw that the wire was not seriously deformed, it should have been tied up when it was calm, the sheets were flat, and there was no sign of struggle and resistance, so I wondered in my heart, the deceased did not have any resistance injuries on his body, why did the deceased not resist when he was tied up with the electric shock? Could it be that the ability to resist was lost at that time? So what could be the reason for him to lose his ability to resist? Could it be that he took sleeping pills, causing him to fall into a deep sleep, and then he was tied up with an electric shock?

In the evening, we had a boxed lunch, and still continued to investigate at the scene, but I didn't expect that the efficient work in the laboratory has achieved results, and the good news is frequent, and the paternity test has ruled out that the deceased was born to Wan Shaoming's parents, which means that the deceased is indeed not Wan Shaoming! I was even more surprised by the results of the poison test, and it was indeed detected with diazepam, a common sleeping pill!

I see, all of a sudden, I suddenly became enlightened, and the process of the crime scene flowed through my mind like a video.

Because of the sudden situation, there were too many excitement and doubts, so we temporarily crammed into a small conference room in the library and started a heated analysis and debate.

I couldn't wait to start talking: "What is the relationship between sleeping pills in blood and electric shocks?" Now it seems that if there were no sleeping pills, it would still be difficult to complete this bundle of electric shock death, and now with this sleeping pills, the analysis is relatively smooth. First, Wan Shaoming gave the deceased sleeping pills, waited for him to sleep deeply, and then tied a wire to his right wrist and energized it to death, so that the whole scene looked very quiet, creating a false impression of suicide. ”

Guo Weitian's gloved hand has never left the suicide note, and the other hand is holding a king-size magnifying glass, the magnifying glass is a common magic weapon used by handwriting experts, this treasure he carries with him every day, he also expressed his opinion: "I still think that the writing of this suicide note is left by Wan Shaoming, I will not change my opinion, according to Su San's meaning, I think her analysis is very reasonable, now the meaning of my suicide note has completely changed, I also believe that it is a forged suicide note, in connection with the current situation, My opinion should also be added to a certain extent, Wan Shaoming not only killed the deceased, but also forged his own suicide note. ”

"But why did he fake such a scene, and what did he want to achieve?" The chubby police officer from the police station was also in the conference room, sitting in the corner, and threw out such a sentence.

"Criminals just want to evade criminal responsibility, but this way of the golden cicada coming out of its shell is really unheard of, so if we don't find a problem, when the body is cremated, the dead will evaporate like this, Wan Shaoming will also disappear, and no one will track it down." A detective said.

"But how can he guarantee that we don't find a problem? After all, if the corpse is found before the **, the appearance is completely recognizable, unless he is sure that the corpse** will not be found before. Another detective said.

"Why not? He was alone in this temporary warehouse on weekends, and if someone hadn't smelled it this morning, he didn't know when he would have been discovered. The detective just said.

"Did you see that? There is a copy of "Introduction to Forensic Science" next to the folding bed, this guy is now learning and selling, but he didn't sell it at a good price, you both got to the point, the key issue I considered is also this, let's ignore Wan Shaoming's killing methods, let's take a look at his action of changing clothes first, if he doesn't understand the ** law of corpses, he won't dare to take this risk. According to the investigation, this room will be on Monday, that is, about two days after the death of the deceased, there will be other staff members to come in, if he can't ensure that the body can be ** unrecognizable after two days, he will never use the means of changing clothes, so I think this "Introduction to Forensic Science" is directly related to this case. "I believe that Wan Shaoming has studied this book, so that the whole analysis will be more logical.

Guo Weitian said with a smile: "It seems that Forensic Doctor Su has met an opponent." ”

"This little thief is learning and selling what he does, isn't that an axe? You see, even if it's a corpse, it hasn't escaped the eyes of Forensic Doctor Su. Hou Yuting said with a smile.

I marveled at Wan Shaoming's shrewdness, and I was also shocked by his cruel shrewdness, a person's concept can make you a hero, but also drive you to become a devil. After all, it is a student of the Chinese department, and if the scientific knowledge learned is used for creation, it is so-so, and if it is used to commit crimes, it is not to shoot yourself in the foot?

Sleeping pills in the blood, death by electric shock, suicide note at the scene, the clothes of the corpse, the scar on the left wrist, all this is already obvious, Wan Shaoming found a stand-in that was very similar to him, gave him sleeping pills, electrocuted him to death, changed the deceased into his own clothes, and disappeared by himself, it can really be said that he is hiding from the sky and the sea, it seems that there is no such a big move as the "Kanglong has regrets" of the eighteen palms of the deity, this Wan Shaoming is really going to get away with it.

As for his motive for committing the crime, I really don't understand it, if it was an accident that caused death, and he did whatever it took to evade responsibility, it can still be explained, but this scene was obviously planned and premeditated, is he just trying to escape the world? So that no one knows that he is still alive in this world? By the way, he committed suicide once in his junior year of high school, and it is said that he later saw a river of blood that shook his confidence. From this point of view, Wan Shaoming is suicidal in the first place, there must be some psychological problems, maybe he doesn't want to die, but he is just afraid of the process of dying, he sees blood, and he doesn't have the courage to continue, what kind of measures will such a person take after killing someone? Maybe just trying to escape the world, escape the world? Where will it go?

This time it's the investigator's turn to get busy, the situation at our scene has basically restored the facts, although we don't fully understand his motives, but what we need to do next is to find out the origin of the deceased and find the whereabouts of Wan Shaoming.

On the way home, I kept thinking, this Wan Shaoming may have committed suicide, but according to his high school experience, it seems that he does not dare to face death by himself, if he is still alive, what kind of state will he live in? Since he has planned this golden cicada shelling case so carefully, it seems that he will not be caught easily, and how will he escape next?

The phone vibrated for a moment, and a text message was sent by Jun Xiu: "Are you free at night?" See you at eight o'clock at Mingxuan Tea Bar. ”

My husband took the initiative to find me, and I was a little nervous.
