Criminal Investigation Notes

In the coffee shop at 02:30 pm, the conversation continues.

Lu Junchi's three views were refreshed. After listening to Su Hui's description, he still hadn't realized it, and lowered his head in thought.

Su looked back at Lu Junchi and blinked, and corrected rigorously: "So, Captain Lu, you used a word wrong just now. The murderer is a pervert, but he is not crazy. He knows what he is doing very well. His thinking He is very meticulous and good at hiding himself. The reason why you found different traces in those cars is because he turned those things into commodities for profit."

"Commodities?" Lu Junchi frowned as he digested the information, "Could it be that Huahua has such an invisible consumer network that specializes in selling these things?"

"In this world, there are women who sell women, children, organs, and even dead bodies. In places where ordinary people don't pay attention, there are too many dirty things that exceed the bottom line What is it that cannot be sold?" Su Hui paused and said, "As long as there is a demand, there will be a market, although it is hard to imagine, but if someone likes these things, someone will provide them. But this hobby There are also certain characteristics, most people who like hands rarely like feet. So these two products are aimed at different customer groups.”

Lu Junchi reacted and said, "So those cars are..."

Su nodded back: "Someone left some evidence and traces on those cars, but those were left by the people who bought them, they were not the murderer. The murderer encountered a problem when selling those stumps, that is his Those customers did not have a fixed and safe place to store their residual limbs, so he thought of using the black market of scrap cars to solve the worries of customers. It also made them feel safer, and his business would be better. And the car keys of those scrap cars may have been bought by him from car thieves."

Lu Junchi's frown deepened, but Su Hui's words well explained the strange state in front of him.

"If my inference is correct..." Su Hui raised his eyes and looked at him slowly.

Lu Junchi sorted out his thoughts: "The murderer may be selling the stumps through the network. He sold those stumps to people with special hobbies, and provided the scrapped cars as their storage room and playground, and told them the rules and methods of use. "

Su nodded back: "The murderer probably also realized the danger of this storage method. He wanted to use multiple abandoned cars to separate the clues from his clients. This plan almost succeeded."

If only the kids hadn't happened to break the window of one of the wrecked cars...

Su looked back at him, he liked Lu Junchi all the way through, which gave him a sense of accomplishment as a teacher.

Lu Junchi continued to reason about the logic in Su's reply, "So, the murderer is customizing according to the needs of customers? Then why would he do such a thing? Is it for money?"

"No..." Su Hui's pupils looked a little hazy under the sunlight, but they were extremely clear, "You can tell from the details of the case and the way the murderer behaved. With enough time, such a person should not be short of money, he may be using this to get in touch with more monsters like him and weaken his sense of guilt."

"Moreover, the murderer also has something he likes. He likes to kill. For a serial killer, the loot can allow him to relive the process of committing the crime over and over again, satisfying their desire for control. He must also like to collect collections, so he would think of selling them in this way." For profit. It's just that his collection may be different from these people's preferences. You haven't found his totem yet..."

Hearing this, Lu Junchi remembered what that person said to him before. Most serial killers would collect some belongings from the victims and use them as their own trophies.During the investigation, those trophies will be used by the police as the murderer's totem because of their uniqueness.This murderer should be no exception.

After explaining all this, Lu Junchi's thoughts became much clearer.

Under the sunlight, Su Hui's face looked a little pale. He had a calm expression and a handsome face. Seeing such a pleasing beauty made people feel that the world is beautiful, but what he said was the darkest in the world. That part is thrilling.

At this time, Qiao Ze came over with his laptop computer, and he could watch several videos on the computer. In the corner of the video, sat a "woman" with long hair, but he was taller than ordinary women. That person His face is not ugly, even a little feminine and charming, which makes him not disobedient when wearing women's clothing. This is probably the reason why no one has discovered and exposed him.

In the monitoring screen, his eyes kept falling on Tong Xiao.

At that time, Tong Xiao, who was in danger, didn't notice...

"The murderer is likely to be this person. Can you confirm the information through his payment method?" Lu Junchi asked. If the other party used the online payment method, then they would be able to find out his identity.

Qiao Ze regretted, "It was all in cash..."

"What about facial analysis?"

"The murderer put on makeup, and the pixels are not enough, so it may be more difficult to find out."

"Notify the store managers of all the coffee shops in Huadu, and let them pay attention to whether there are similar customers. If anyone goes missing, they must contact the police immediately." Lu Junchi quickly made a decision, "Called the other two coffee shops and nearby surveillance cameras, See if you can locate the suspect's route, or vehicle."

Lu Junchi thought about how else to find out the murderer.

Su Hui finished his lunch and stood up: "Thank you Captain Lu for your hospitality, and I can help you with a little idea." He paused and said, "I think you can look for it, after he visited the coffee shop The garbage sent out by those coffee shops."

"Trash?" Qiao Ze sighed.

"Yes, garbage can tell us a lot of information, especially the tableware, paper cups, and food scraps that the murderer ate. If we are lucky, there may be his fingerprints and DNA on them." Seeing Qiao Ze and Lu Junchi in a daze, Su Hui went further He explained, "Generally, the garbage in coffee shops will be used in special garbage bags, and the garbage will be sent to the garbage disposal site, and it may not be landfilled in a few months."

Qiao Ze frowned, "But there are so many rubbish, how can we tell which ones are left by the murderer?"

Lu Junchi thought for a while and cleared his mind: "According to the monitoring, it can be found that the murderer usually arrives at the store when there are few customers in the afternoon. There are not many customers at that time. According to the regulations of the coffee shop, employees have to empty the garbage before work, so the suspect The garbage left by people must be in the garbage bag with the least number. Many guests will throw away the receipts, which can help us determine the date and time."

You can see what the murderer bought on the surveillance. He has been here several times, and they can collect the garbage of the corresponding date for comparison.

"Captain Lu is smarter!" Qiao Ze was excited, "Thank you, Teacher Su..."

Lu Junchi also thanked Su Hui. This method is a delicate task. Although it is a bit troublesome, it is theoretically feasible, but in addition to hard work, it also requires a little bit of luck.Perhaps the murderer's fingerprints and information can be found soon, or it may take a long time to investigate.

Fortunately, the murderer's crimes and behavior have begun to gradually become clear from vague.

A policeman came to report to Lu Junchi. After he finished dealing with the problem, Su Hui had already left the restaurant and crossed the street in front.

Lu Junchi just remembered that he forgot to ask Su Hui's WeChat.

Five days after the discovery of the stump, the case finally had a breakthrough.

In the early hours of the morning, the criminal police who were in charge of tracking captured a sneaky man next to the third group of abandoned cars.

After checking, they quickly confirmed that this person had left fingerprints in the abandoned car.

When Lu Junchi arrived at the headquarters in the morning, the man had already been locked in the interrogation room and the interrogation had begun.

When he entered the observation room, Zheng Bai and Qiao Ze were asking questions inside.

Seeing Lu Junchi come in, Xia Mingxi, the female criminal policeman in charge of recording, handed over the relevant documents.

Lu Junchi's eyes scanned the form. This man's name is Zhan Xingrong, a small boss who manages decoration materials. He is 32 years old and has received higher education. He looks like a chubby little man.If there is no conclusive evidence, it will be difficult for people to connect the person in front of them with this murderous case, let alone with those strange hobbies.

"...I'm really innocent, and I'm also curious... Besides, when I bought it, I didn't know whether it was a dead person or a living person. I have nothing to do with this murderer."

Qiao Ze pierced him with a sneer: "Mr. Zhan, you went there last night, didn't you think it was a fluke and wanted to take the things back?"

"I..." Zhan Xingrong was at a loss for words when his mind was punctured, he wiped the corner of his eyes, "If I'm like this, I won't break the law..."

"When you made that deal, you have already committed a crime." Zheng Bai continued to press, "You'd better tell the truth now, where you bought it from, maybe you have a good attitude and you can ask for a lighter sentence."

The little fat man began to cover his face and cry: "Don't tell my family about this. If someone finds out, I will die socially..." This secret is like a skeleton he hides in the closet.

Zheng Bai didn't sympathize with him, and said coldly: "You confess first, and then we'll talk about the rest."

Zhan Xingrong's eyes were red. He hesitated for a while, knowing that he couldn't get rid of the crime, he said honestly: "I was introduced by an old man in the circle before. He said that there are reliable people who ship the goods. Expensive... Then I added an account on the Internet with the mentality of giving it a try. At first, I was also worried about being cheated. After all, it was a lot of money, and no one's money was blown by a strong wind. I tried to check I found out that his IP is abroad, and I can give you the number, but I haven't seen him log in since then..."

"The method and time of the transaction?" Seeing that Zhan Xingrong quickly recruited, Qiao Ze continued to ask.

"Initially it was 15 a pair, but I said there were not that many, so it became [-]. I said, I have no place to store it, so he said, add another [-], and he can provide scrap cars for trading .That person...he only accepts cash, and the transaction was carried out in a designated scrap car. I received a car key, opened the door and put [-] in the drawer at the front of the car. The next day I received two more A car key, and instructions. When I went, I found a box under the back seat of a car..."

Speaking of this, Zhan Xingrong's eyes flickered with fear: "I... I really thought that he was able to get the goods because he worked in the crematorium. If I know there is a problem, I will do it if I have the guts." dare not..."

"What else did the other party say? Or are there any other details you can think of?"

"At that time, that person had a lot of rules. For example, the time to go should not be earlier than ten o'clock in the evening and no later than six o'clock in the morning. When you are in the car, you must lock the door and cannot turn on the lights. You can only use the flashlight and take it out. From now on, I can only watch it in another car with black windows, and put it back in the box after reading it..."

Qiao Ze asked the key question: "Do you know the name of the person who delivered the goods?"

Zhan Xingrong paused and swallowed: "I only know that people in the circle call him 'the butcher'. He can meet people's various needs, and even spend enough money to have..."

Hearing this, Xia Mingxi, who was in charge of recording, couldn't stand it any longer, and said in a low voice, "It's really perverted...to actually take out the victim's body and sell it."

Lu Junchi crossed his arms and said, "Several people have been killed. What do you expect such a person to have a moral bottom line?"

What surprised Lu Junchi was that the situation described by the victim was basically consistent with Su Hui's previous analysis.That Mr. Su really didn't look as simple as it appeared on the surface.

The case finally made progress, and the police finally knew who their opponents were...

Butcher.

Treat innocent women as lambs, even as his commodity.This murderer really lived up to his name, bold, extremely twisted, and thoughtful at the same time.

When Su Hui came to Baihushan Prison for the second time, it was a little later than the last time. He was already familiar with the way, greeted the prison guards, and still came to the interrogation room.

After Song Rongjiang came in, he was obviously more decadent than the last time he saw him. His hair was messier and dark circles appeared under his eyes.

There are less than ten days before Song Rongjiang's execution. He has always been big-hearted, but when this time really came, he also began to be afraid.

The countdown to life put him under tremendous pressure.

No matter what he thought in his heart, his body began to instinctively resist and fear death.

Song Rongjiang took the cigarette that Su Hui handed over, and first said: "Mr. Su, you are late. I thought you might not come."

Before Su Hui appeared, he had been waiting a little restlessly.When the countdown to death began, he didn't know why, and he began to look forward to this conversation.

Su replied: "I'm sorry, there is a little traffic jam in the city today."

Song Rongjiang was stunned for a moment before realizing: "Today is Friday." Then he looked at Su Hui and asked, "Will you come to see my execution?"

Su Hui thought that the relationship between them was successful. Now, Song Rongjiang no longer had the initial precautions. He even had some subtle dependence on him because no one had visited for a long time and he was near death.

Su Hui asked, "Do you want me to come?"

Song Rongjiang hesitated for a moment, as if imagining what Su could do when he came back, then he shook his head and said, "Forget it, it's better not to come, it's nothing to see."

Today's topic is a continuation of the last topic. Su Hui focused on Song Rongjiang's feelings towards people, including towards men and women.

Those people all existed in his life, relatives, mother, father, classmates, teachers, colleagues.

Su Hui asked very carefully, as if he hoped to build up the entire first half of Song Rongjiang's life through the relationship between these characters.

Among them were some people and relationships. Su Hui had done his homework in advance, and even called to inquire about them. As the conversation progressed, he got closer to Song Rongjiang's world.

He uses different words when referring to men than when referring to women.

Su Hui sensitively found that he had strong doubts about women, as well as a sense of contempt and disgust.

Just like in the first case, he turned a deaf ear to the victim's denial, and he only believed in the result he thought. This attitude runs through all his interactions with women.

Fundamentally, Song Rongjiang believed that many women were lying, and he didn't believe them.

Correspondingly, he only believed in his own judgments about them, some of which were even made up by himself.

Su Hui judged that this habit may be related to Song Rongjiang's mother-child relationship, or it may be derived from the betrayal and injury he suffered when he was a teenager.

These are also related to his victim selection.

Su Hui was also able to capture a sense of nostalgia from some of Song Rongjiang's words, what he was looking for.

But in his repeated trials, he did not find a clear related person or event.

Song Rongjiang protected this very well. Whenever Su Hui asked related questions, he would bypass them in a hurry.

Obviously, like Pei Weiwei's location, this is Song Rongjiang's protection point, a forbidden area that others cannot know and cannot enter.

Su Hui realized that Song Rongjiang would not tell the truth on these issues.

He wants to take these secrets with him to death.

As Su Hui repeatedly asked about his youth, Song Rongjiang finally showed obvious impatience. He took a deep breath and said, "Those things have nothing to do with my current crime. When will today's conversation end? "

"It's almost over." Su Hui said, his head coughed a few times due to the smell of smoke, and he once again directed the question to some details of the day when the crime occurred. He needed to bring the topic into Song Rongjiang's comfort zone, so that he could If you look forward to the conversation, you will tell more useful information and more valuable truths.

Song Rongjiang was obviously excited again.

"You know? Teacher Su, when they stop struggling, it feels so wonderful. I feel like I have completely merged with them." Song Rongjiang paused for a moment, his eyes sparkled, and he spit out a whiff of white. Yan, "I feel, I returned them to death..."

This is Dickinson's poem, and she has a double understanding of death.

Su Hui took a deep breath and coughed a few more times due to the smell of smoke.

He can read these people, he can walk into their thoughts, like walking into a maze, he unravels the mysteries one by one, but that doesn't mean he likes them.

But he had to, because it was the only way to uncover dark secrets and unravel haunting mysteries.

Su Hui could feel that he was getting closer and closer to the answer he wanted to find.
