Chapter 16 Chapter Sixteen

This sense of disfluency is entirely an intuition of illogical thinking, and sometimes intuition is useful, but you can never convince anyone with an intuition of illogical thinking.It can only perceive the right and wrong directions, and cannot solve any practical problems in case detection.So you still can only use logical thinking to find the gaps and loopholes in your current job. I stood up and paced to the window, trying to clean up all the clues again. The most certain is the cause of death and the manner of death.The hemorrhage points in the conjunctiva and lungs of the deceased confirmed that the deceased had indeed died of suffocation, and the completely normal carbon monoxide and hemoglobin levels in the pectoralis major muscle of the three deceased further ruled out gas poisoning.

In this way, we can give a more reasonable explanation for the somewhat abrupt gas jar at the scene.Since the cause of death of the deceased was suffocation, the gas jar can only be considered to have been used to set fire to destroy the scene.As for the two superimposed cut marks on the gas pipe, a reasonable explanation is that the perpetrator was frightened by the jet of gas.The gas pipe twisted like a strange python, and gave off a pungent smell. In a panic, the criminal cut the gas tank a second time near the pressure valve.Also out of fear, he ended up not lighting the gas. Just like playing jigsaw puzzles in real life, if you can't complete the whole jigsaw puzzle, you might as well put some more confident pieces together first.Let's finish part of the puzzle first, I console myself.

After determining the cause of death and the manner of death, the next step is to determine the purpose of the crime or the motive for committing the crime.It seems absurd to use tangible and qualitative on-site evidence to infer criminals' psychological activities, but the motive of committing crimes often plays a decisive role in the direction of detection.If we think this is a vendetta, we need to start with whether the family has any vendettas with outsiders, but if we think this is a case of seeking wealth that randomly entered the victim's family, our focus should be to investigate habitual thieves and crimes. Personnel, count the loss of family property, and strictly guard the channels for selling stolen goods.

On the surface, killing all three family members present in a row seems more like a premeditated vendetta, but based on experience, I do not agree with this speculation.A premeditated vendetta should carefully prepare the crime tools. A long-sharpened knife and a bomb are logical, but using tape and plastic bags to cover the victim's mouth and nose is more like improvisation at the scene of the crime. crime tools.What's more, it has been proved that the piece of cloth that stuffed the daughter-in-law's mouth was torn from the bed sheet at home. The murderer also tore a long strip from the bed sheet and bound the father-in-law's feet.

Could it be the murder after theft or robbery?The family's son has not been found yet, and we are temporarily not sure what important property was lost in the family. Although there are indeed traces of searching for property at the scene, my intuition tells me that this guess is not correct. Once again I was blocked by my intuition. I desperately recalled every detail of the scene, and those complicated scenes were switching rapidly in my mind. Suddenly, the scene of the living room was frozen in front of me.Yes, it is the living room, and it is the coffee table that makes me feel wrong.The tea table showed signs of being moved. Unlike all the fighting scenes I saw, it was moved in the wrong direction and angle.

I can't be sure that my memory is completely accurate, so I have to go to the scene again. When I saw the coffee table still in place, I couldn't restrain the ecstasy in my heart and almost jumped for joy.Judging from the general placement of the coffee table, its left and right ends should be on the same level, and one end will be close to the seven-shaped corner of the sofa, but I found that the distance between the coffee table and the sofa exceeded the normal range.Out of caution, I observed the coffee table more carefully. I must know that no matter how hardworking the housewife is, there will still be a little more dust under the original position of the coffee table.The dust, which is hard to see and usually never noticed by anyone, confirmed my judgment. I found a little floc, and it seemed that the coffee table was indeed pushed.Therefore, the moved coffee table, the broken teacup and the tightly locked doors and windows without any damage form a chain of evidence—the murderer is a guest of this family!

The whole scene finally unfolded smoothly in front of me.The murderer knocked on the door and paid a polite visit to the owner, who poured hot tea for the guest.At this time, for some reason, the murderer suddenly became angry. His sudden action tripped the coffee table and broke the teacup.The owner who was caught off guard was subdued and killed by the murderer with sudden evil thoughts. After committing the crime, the murderer cleaned up the fingerprints at the scene, perhaps to steal the sheep, or to disguise the scene, he flipped through the property in the house.Before leaving, the murderer wanted to set fire to destroy the evidence, but finally gave up because he was afraid of harming himself.

What is the relationship between the murderer and the master?Why the sudden rage? Where is the "missing" son now?What is missing from the family?I can't wait to find the answer to my next question. "What do you think? Is this case a premeditated murder or an accident?" At the case analysis meeting, the deputy director was a little impatient and knocked on the table to interrupt my reverie. I blushed, it seemed that this was not the first time the deputy director had asked me.It is an unwritten rule for the forensic doctor to speak at the end of the case discussion meeting. I was also considering the new evidence and new clues brought by the criminal police, but I didn't hear the deputy director's question clearly, so he had to knock on the table to remind me.

I didn't rush to answer the deputy director's question, but pondered for a while and said, "I think it's by chance." There was a lot of whispering at the venue, it seems that everyone does not agree with my point of view. I sorted out my thoughts, and then said: "I mainly think about the tools of the crime. If this case is premeditated, the tools of the crime should be more aggressive, such as knives, guns and sticks, etc., but what we found at the scene The main murder tool was tape paper. In addition, during the autopsy, it was found that the suspect stuffed a floral cloth into the daughter-in-law’s mouth in order to prevent the victim from screaming, which was also one of the causes of suffocation. We found a torn bed sheet at the scene. The pattern of the piece of cloth found in the mouth of the daughter-in-law is consistent, and the fracture coincides. It can be seen that the cloth was not carried by the suspect, but was obtained locally. Tape paper is also a daily necessities. All of which do not fit the general characteristics of premeditated crimes.”

The venue was quiet for a while, obviously most people were convinced by me, but at this moment Weicheng's voice rang out: "The criminal suspect didn't commit crimes sooner or later, and he just showed up when the only man in the family was out. Isn't this too 'coincidental'?" Although Weicheng is usually silent, if he asks a question, it will be difficult to answer.What he said did make sense.The experience of fighting crimes all the year round makes us believe in coincidence more than anyone else. The tools for committing the crime were obviously not carefully prepared, but the timing of committing the crime seemed to have been carefully planned and selected. This is indeed an inexplicable contradiction.

It seems that the perpetrator's visit to this family was planned, but the purpose of coming here was not to kill people in the first place. I quickly corrected my judgment. So, what is the purpose of the murderer's visit?Why did he negotiate with the victim to visit at a time when the male master is not in and his in-laws are? The word "love killing" came to my mind, but I couldn't say it out, because there is no evidence to confirm my intuition, or guesswork. I need proof so badly. I like to come to the supermarket and watch the bustling crowd quietly, it can make me feel relaxed.I don't care whether they are men who come and go in a hurry or housewives who are fastidious, whether they are peaceful old people or naughty children.They change in front of my eyes like floating clouds, and what they bring me is the warmth and steadfastness of the secular world.Being away from all the people who care about me and those I care about, and being exposed to dark, melancholy and mysterious crimes at work, I really need the warmth of this world. The cell phone rang suddenly, interrupting my intoxicated void. "The male owner of that house has been found. Just now he went home and carefully identified the things in the house. Guess what was missing at the scene?" "Shoes?" I said calmly. "How do you know?" Weicheng's astonishment greatly reduced his excitement just now. In fact, the reason why I can guess the answer is very simple.Apart from the fingerprints, what excites Weicheng doing the trace analysis most is the footprints. Now that the fingerprints have been cleaned up by the murderer, what else can make Weicheng so excited besides the footprints?What's more, the only trace of foreign footprints on the scene - the shoes were not found. Weicheng has been troubled by this for more than a day. "Just kidding, who doesn't know that your specialty is 'making shoes'? What excites you not about shoes?" "Yes, there is a pair of slippers for guests missing." Weicheng obviously understood what I meant. Carefully taking away the shoes I had worn undoubtedly proves that the murderer has a good psychological quality and strong anti-investigation ability, but all the acts of covering up evidence will become a new evidence in itself-only one pair of shoes is taken away, which further confirms the murderer only one person. Our inference that the murderer was a guest greatly narrowed the scope of the investigation, and soon three suspects came into view.Two of them are creditors to the family, and another person who has had emotional entanglements with his wife and recently appeared in the city is undoubtedly suspicious, but all three of them swear that they don't know about it at all, and There is circumstantial evidence to prove that they did not have time to commit the crime, and the case that seemed to have broken through the mystery suddenly went off fire and fell into another deadlock. My intuition tells me that this case is related to emotional entanglements.The problem now is that we don't have any direct evidence to prove that he is the murderer, not to mention that the other two people also had the motive to kill and kill in anger. The image of the hostess cleaning the room at the scene with bright and clean windows came to my mind again. She was wiping the sweat again, with that heart-warming happy smile on her face. Her happy smile slowly became transparent in front of me, and disappeared without a trace, replaced by a hideous face when she was struggling desperately after her mouth and nose were covered. What is she going to tell me?What else can she tell me? The bounden duty of a forensic doctor is to talk to the dead. Her life has disappeared, but the skin that has not disappeared is the object of my dialogue. I must understand her voice, no matter how erratic and elusive her words are. I entered the autopsy room again. I hardly noticed that the sun had set in the west, and the stars all over the sky were blinking at me through the window of the dissecting room.When all the mysteries are revealed, you will feel that the answer is so simple that it is actually right under the tip of your nose.The answer I was looking for was right in front of my eyes, and I hadn't found it until now because I paid too much attention to the body itself and ignored other things in the dead body. tape.The answer is on the tape.Adhesive tape is very convenient as a tool to bind the victim. I have found that adhesive tape was used as a crime tool more than once at the scene. In this case, the first thing that caught the eye when the victim came into contact with the adhesive tape was the adhesive tape, which made me ignore it. the most obvious evidence. Adhesive tape is a very convenient tool for committing crimes and is also the best fingerprint collector.The murderer cleaned the room, but did not take away the tape he used to kill. So when a full fingerprint appeared on the tape, I almost screamed with joy, but instead of screaming, I searched through all the tape.Binding and killing three victims, the murderer used up an entire roll of tape and threw the empty roll between the father-in-law's feet.It was because the tape was used up that he tore off the sheet to bind the father-in-law's feet. A total of 7 complete fingerprints, I believe Weicheng will give me a clear answer. With such solid evidence, I am confident that my colleagues will be able to break through the murderer's defenses and get his true confession.Although the suspect was able to kill three people in a row without delay in the whole case, and he was able to clean up the scene carefully afterwards, showing a very strong psychological quality, but the gas jar still exposed his weakness.Although he has no pity for other people's lives, he still cares about his own life very much. The death penalty is a huge threat that can break through his defenses. When I actually met him face to face, it was already a few months later. At that time, he already understood that although he carefully concealed it, the evidence was solid, and it made no difference whether he said it or not. He is not as vicious as I thought, like Butcher Zhenguanxi, nor is he full of flesh. On the contrary, he looks gentle and wears a pair of gold-rimmed glasses. When I asked him how he killed the three victims without alerting the neighbors next door, he answered very frankly, and even smiled at me: "The best way to kill someone without any resistance is to You have to convince them that they can survive." I was at a loss for words.This is really a good answer, and I should have thought of this earlier.The three victims were taken to different rooms, they did not witness the other being killed, and the murderer slowly wrapped the tape around the victim's nose in circles, which prevented them from calling for help.He can achieve his goal as long as he deceives the victim that he just doesn't want them to call for help and doesn't want to kill them. I laughed at myself, feeling that I was still at a disadvantage in the battle of wits with the suspect, why didn't I think of such an obvious and simple answer. So I asked him a second question: What was it about the mistress that annoyed him and made him feel bad? I already knew he had a college romance with the hostess, which, like many college romances, didn't blossom—grad assignments separated the pair.I don't want to comment on the relationship.I'm just wondering how a love affair turns into a murder? This time he didn't want to say more, he just said "she still keeps our photos" and fell silent. I wanted to keep asking, but I swallowed the words again. What is there to ask.There are only so many stories in Love, Hate and Sea, but every day a different protagonist is staged around the world in turn.A woman, a sliver of past good feelings, may be a red cape in front of a bull in the eyes of a man driven mad by jealousy.It may be that the memories of the good times in the past reminded him of the "betrayal" of the year, or it may be that the memory of the past made him feel that this woman was flirtatious. What is no longer important, what is important is that I know that this is a love-to-hate relationship. When I left the prison, the black muzzle of the gun on the watch post made me feel a bit like a pain in the back, even though I knew that the muzzle of the gun was not aimed at me.Just as the iron gate of the prison slammed shut, the sentence of "Buddha said the Sutra of the King of Wonderful Colors" circled in my mind again. From love comes sorrow, from love comes fear. If you are separated from your beloved, you have no worries and no fears.
