It is often said that seeing is believing, hearing is false, but this sentence is not applicable to the criminal police, many times what you see is what the criminal suspect wants you to see, so as to achieve the purpose of confusing, hiding yourself or clearing the suspicion. Individual high-IQ criminal suspects can firmly plant the evidence of their crimes on another person, so as to achieve a perfect crime.

Yes, I am a criminal investigation team leader, I have been in this industry for more than ten years, and I have encountered many bizarre murders over the years, and the criminal suspects' criminal methods are also strange, but all have only one purpose, and that is to try to escape the punishment of the law.

Below I will pick up a few twists and turns of the murder case that I have encountered over the years to tell you, because of the confidentiality issue, some details are inconvenient to disclose to you, so the names mentioned below are all made up by me racking my brains, if there are similarities, I'm really sorry, don't sit in the right seat.

At the beginning of July 2002, I graduated from the police academy and was assigned to the Songhai City Public Security Bureau, where I now worked. I was so excited on the train that I expected to become a Sherlock Holmes-like detective in the future, and I wanted to solve a big case immediately to prove my ability.

After a period of excitement, I found that the grassroots were not as busy as I imagined, but very boring, and they were usually trivial things, which could be solved without the help of the criminal investigation team.

I thought that I would eat and drink in the criminal investigation team for the rest of my life until I retired, but a police call broke the ordinary life of the police force and officially enlightened my career. To be honest, before I received this report, I never thought that there was such a disgusting and cruel murder method in the world.

On the morning of the seventh and a half months, as always, there was nothing to do, and Sun Jianguo, the deputy captain who had not been back from studying abroad, lit a cigarette and took me and my senior sister Liu Yefang and a few people in Kandashan, talking about the time when the spit was flying, and suddenly saw the neatly dressed captain Li Jun walking in quickly,

"Someone found a black garbage bag on Songhua Street in the east of the city, the bag was bulging with minced meat and women's hair, according to the response of the police in the jurisdiction of the scene, this may be a murder case, the above has paid close attention to the incident, and ordered us to go to the scene to investigate."

I couldn't help but jump up in my heart, when I was in the police academy, we also heard about the murder and corpse mutilation, but this is the first time I have met it, Li Jun's eyes swept around and saw that I was stunned, and said: "Scared? Then you stay at the police station and don't go to the scene, I guess this case is not easy to solve, it's a hard stubble. ”

"Go, go, go! I'm not afraid, I just didn't react. I hurriedly explained, and at the same time looked at Li Jun expectantly, for fear that he would not take me.

Li Jun looked at me, whispered a stunned word, and then asked me to inform the trace inspector Zhang Bin to summon the criminal investigation team to rush to the scene of the incident, the city bureau is not far from Songhua Street in the east of the city, and it takes more than ten minutes to drive. The scene has been set up by the police station in the jurisdiction, because it is morning, a large number of people go out to buy food, here are all stopped to watch, Li Jun got out of the car to see this scene, frowned and asked the police in the jurisdiction to evacuate the onlookers, and said to me seriously:

"The corpse shredding case is no different from other cases, it is easy to cause a large-scale panic in the society, and now it has been seen by so many people, so we can only narrow the scope of influence as much as possible, you go up to help, and evacuate the irrelevant people to 20 meters away from the cordon."

The garbage bag containing minced meat was found at the garbage station, it rained heavily last night, and it was dog days, so the environment at the scene was very poor, the light black sewage flowed down the steps of the garbage station, and the foul smell was permeated nearby.

The person who found the garbage bag was a nearby resident in her sixties, who was sitting on the ground at this time, staring at a black garbage bag in front of her with a frightened face.

I curiously poked my head to look at the garbage bag surrounded by the police, and the first thing that caught my eye was dozens of green-headed flies flying around, with a large clump of long hair stuffed on the top of the garbage bag.

I couldn't help but retch, and immediately turned around and walked to the police car, taking a few breaths of fresh air.

About two or three minutes passed, I felt a little better before returning to the garbage bag, this time I saw the minced meat in the garbage bag, when I was in the police academy, I also saw a lot of photos of the case of the broken corpse, but the photos are basically dismantled, and there are few pieces that are cut into thin slices like in front of me, just like the minced meat slices used to make barbecue skewers. And the meat slices are not normal blood red, but as if they have been boiled in boiling water, the surface is miserable white, and some meat slices have deteriorated due to the heat, and even have a layer of green and fluffy fine hairs.

Trace inspector Zhang Bin was leading people to collect evidence, because there was not enough manpower, he beckoned me to help, I wanted to refuse, but thinking about my current identity, I had to endure the feeling of vomiting and squat down to help.

Zhang Bin first handed me a pair of gloves and said to me: "In the process of collecting evidence, you must not stain your own traces on the evidence, and you must preserve the integrity of the minced meat slices like this, which will be helpful for the forensic autopsy." ”

Put on the gloves, help Zhang Bin transfer the minced meat in the garbage bag to the evidence box little by little, and gently twist up a layer of minced meat, even through the gloves, I can still feel the slimy touch from my fingertips, a bit like the mucus secreted by slugs, and a bit like the liquid of shampoo, very sticky. Tilting his head to glance at it, the slightly blood-red liquid was dripping down the finger seam in a filamentous shape, and then he looked at the sliced minced meat covered with green hair in his hand, and suddenly he had goosebumps all over his body, and shivered.

Although the layer of minced meat on the surface has some green hairs, it does not have much odor, and when it is cleaned to the second layer, there is an extremely disgusting rancid smell in the face, and wearing a mask cannot stop it. It smelled much heavier than the smell coming from the garbage dump, but it smelled more like rotten eggs. After I finally recovered from the smell, I heard Zhang Bin say calmly: "In summer, the temperature is high, the decay and deterioration of the corpse will be accelerated, and the minced meat on the surface will be almost dispersed because of contact with the air, and the rest of the smell will not be dispersed because of the contact with the air, so that's it." This taste is actually a mixture of putrescine and cadaverine, how to describe it specifically, such as a piece of meat stuck in the teeth, and the taste is similar if you don't pick it out after half a month. ”

The surface of the second layer of minced meat does not have green hairs, but it is covered with a shiny liquid that has accumulated from the liquid that has previously flowed from between the fingers, and the muscle texture of the minced meat can be clearly seen through it. When I saw this scene, I just heard Zhang Bin describing the smell of corpses, and the two of them together couldn't help but turn around and spit out.

Seeing that I was unwell, Zhang Bin did not force it, beckoned another person to help, and asked me to go to Team Li's side.

After spitting up, I felt that my mouth was a little sour, and the air was also filled with the sour smell of minced meat, so I was afraid of throwing it out again, so I hurriedly walked to the garbage station that was piled up like a hill, and helped Li Jun rummage through the garbage in the garbage station to see if I could find any more useful clues. After rummaging for more than an hour, every garbage bag in the garbage station was opened and rummaged, but nothing suspicious was found.

Li Jun walked out of the garbage station and took off his gloves, wiped a handful of beads of sweat the size of beans on his head, and said: "Let's go, don't look for it, it seems that I feel right, it is an old Jianghu who did this, it is impossible to throw the body in one place, maybe it has been pulled away a long time ago." ”

After a pause, his eyes turned to Liu Yefang, who was in charge of asking: "Xiao Liu, how is the situation of the aunt?" ”

Liu Yefang opened the record book and replied: "According to the aunt, she came here at seven o'clock this morning, rummaging through the garbage bags according to her usual habit to see if she could find the discarded bottles and sell them to subsidize the family, and soon opened the bag containing minced meat and hair, and was frightened to the ground at that time. ”

Li Jun pondered for a few seconds after listening to this, and then instructed a few policemen around him: "A few of you go to get the surveillance video of the main intersection around the garbage station, the time period is from a week ago, and send someone to the sanitation department to inquire, how many times a day is the garbage station on Songhua Street in the east of the city, where is the collected garbage placed?" ”

"By the way, when they collect garbage these days, pay attention to find out if there is a garbage bag containing a bag of minced meat, and report it immediately if there is."

Several people were ordered to go their separate ways quickly, and the rest of the people searched the scene again, and when no new evidence was found, they could only collect the team and return to the bureau.

"Pony, can you rely on these things to determine the identity of the victim and the time of death?"

Li Jun shouted to the Criminal Investigation Department of the forensic doctor Ma Zhiyuan, pointing to the minced meat and hair on the table.

Maybe because of the perennial contact with corpses and other things, the expression on Ma Zhiyuan's face did not change as drastically as ours, his brows were twisted into a word, and he cursed in a low voice, and then began to carefully examine the human tissue that was packed in the bag, and said after a while: "The identity can be determined by detecting the DNA, these pieces of meat seem to have been cooked, but the DNA does not break at high temperatures, but the hydrogen bonds are opened, and the double strands become single strands, and DNA hybridization technology only needs a single strand of DNA." ”

"But it's still a bit of a problem, because for the time being, it's impossible to determine that the minced meat and hair come from the same person, so it takes a lot of time to take multiple samples to be sure. And if there is no data on this person in the DNA bank, even if it is found, it will be difficult to determine the specific identity of the victim. ”
