Criminal Investigation Notes

Huadu, after nine o'clock in the evening, this is a peaceful and ordinary night, the whole world is quiet.

The street lights on the side of the street are lit up one by one, together with the colorful neon lights on the side of the street, it outlines a beautiful night view of the city.

Autumn in Huadu is very short, and it seems that winter will enter soon.

A bus carrying passengers slowly left the platform.This is a big station, and many passengers went down. The crowded situation was instantly relieved, and the quarrels and unhappiness disappeared.

The car was very empty all of a sudden, not to mention that everyone had a seat, there were several empty seats, and only half of the car could be filled.

On the bus at night, the driver turned on the lights, and the whole car was filled with warm orange light. The car drove quickly and steadily. People who had been busy all day were eager to go home.

Suddenly a middle-aged man asked a question: "Oh? Whose bag is this?"

He found the bag under the seat next to him. The bag was black. In the dark night, it would be impossible to find it without looking carefully. The middle-aged man picked up the bag, and it felt a bit heavy to the touch.

There were not many people in the empty car, and the others didn't make a sound after hearing this.

The middle-aged man walked forward carrying his bag in a strange way, and said to the driver: "Master, someone left the bag on the car."

The driver was still driving, and yelled twice to help: "Whose bag?"

No one answered.

The driver asked the middle-aged man again: "Did you see who left this bag there just now?"

The middle-aged man said: "No, I didn't pay attention, I just came up not long ago."

The driver asked again, "Did anyone see who put down the bag?"

No one responded, and other guests began to discuss: "What if it is a valuable item? It looks like a very new bag."

"I'll come and get it later, right? Put it at the terminus for him?"

"How could you forget such a big bag? It couldn't have been put here on purpose!"

"Is there anything missing in this car? The driver is no stranger to it."

"Oh, there seems to be some noise in this bag." A girl sitting very close said suddenly.

The car suddenly fell silent, and everyone fell silent.

Sure enough, there was a strange sound coming from the bag, it was a slight beep, like the sound of an electronic alarm clock.

An aunt said: "Let's check it out, don't worry about anything bad..."

After hearing this sentence, the expressions of the people in the car changed, and the middle-aged man unzipped the bag with a squeak.

Inside the bag was a square iron box with red numbers flashing on it...

It was another dream. Su Hui could clearly tell that he was in a dream, but everything in that dream was so real, as if it had happened in real life.

Su Hui was a little unclear for a moment, whether this was a dream, or a memory that suddenly appeared in his mind.

This seems to be happening more and more frequently recently.

He often dreams, but after waking up, he can't remember many details of the dream.

"...I see, Mom, I will go back this weekend, ah, as I said, I have already made friends, so you don't have to arrange a blind date for me."

"What? Take it home for you to see? This is a bit too fast, you have to consider the other person's feelings, don't you?"

The mother's voice came from the other end of the phone, and she asked cautiously: "Then... what does she look like? Is she good-tempered?"

Su Hui in the dream responded casually, and then said: "Mom, you have to trust your son's vision. He is good-looking, virtuous, and very gentle. Well, there is nothing wrong with him except that Dink doesn't want to have children..."

My mother was not very satisfied with this, but she heard that he didn't mind, so she didn't want to say anything, so she just left a word: "This... you should discuss it again. If you don't have children, you will be lonely."

Su Hui advised her: "Actually, if you want to experience the pleasure of growing up, wouldn't it be better to have a cat?"

Mom snorted: "Isn't it? If I had raised a cat back then, it wouldn't be so eloquent."

Su Hui quickly went to coax her: "Mom, I recently bought you a purple sand tea set, and I plan to take it home next time."

After hearing this, my old mother immediately smiled and asked him to take pictures.

Su Hui asked sourly, "Can cats know?"

Mom shook hands and made peace: "Okay, okay, isn't it the cat you mentioned first? You will know in the future, as long as the children are safe and happy as parents, the rest will be in the back row. Is your dad and I afraid that you are usually too cute?" Are you afraid that you won’t be able to take care of yourself if you’re too lazy? You’ll find another similar one, raise a cat, and starve the whole family?”

The mother nagged something again, Su Hui hung up the phone, walked in the corridor of Building No. [-], and came to the corner, where he saw a person in overalls squatting in front of the usually unmanned vending machine.

Su Hui: "..."

Worker:"……"

Sue asked the worker, "Did you see anything else in there?"

The worker was stunned for a moment: "Are you talking about this..." As he spoke, he handed over a lunch box, "I also said that the drinks in this machine are almost full, but there is a bento at the outlet. I just now Still thinking, our vending machine is so smart."

Su Hui smiled and thought to himself, it's just that you met today, and occasionally there will be umbrellas, roses, snacks and small gifts here...

He went upstairs, put the bento box in a drawer, and took out a strip of fluorescent paper from it.

That pack of fluorescent paper, this is the last one.

Su Hui skillfully and quickly folded it into a star, and placed it next to the lunch box.

The phone beeped: "I brought you chicken soup today, did you receive it?"

The corners of Su Hui's mouth raised unconsciously: "If I'm 5 minutes late, I'll probably be taken away by the vending machine repairman."

The other party replied after a while: "I'm sorry, I will pay attention next time."

"I don't blame you, have you got on the high-speed rail?" Su Hui remembered that he seemed to have said before that he was going on a business trip today, so he put it in earlier.

"Fortunately, it went well. Team Luo is with me. You have to remember to eat on time."

This business trip may take half a month, Su Hui said again: "The stars this time and the lunch box next time will be given to you together."

"I already have 99 stars, and if I add this one, it will just make up the whole."

Su Hui hesitated for a moment and typed: "Then let's meet when you come back, and I can give you the last star with my own hands."

Immediately, the other party replied: "Okay!"

Su Hui turned on the computer, and after entering the password to log in to the system, a file to be checked popped up.

Fine sand again...

He opened the file, which was the latest bombing case, two people were killed and two people were injured. This is already the eighth victim of the fine sand bombing.

For several months in a row, more than a dozen crimes were committed. This mysterious fine sand is simply haunted.

Su Hui frowned. He had done so many criminal profiles, but this case always exceeded his expectations.

At first, the name fine sand was derived from some sand grains found at the scene of the bombing. This kind of explosive was self-made, and the inside was insulated with a layer of sand. When it exploded later, some colored fine sand grains would be left on the scene. The fine sand Hence the nickname.

What Su Hui didn't expect was that such a bomber who used a homemade bomb was changing rapidly. He seemed to be doing his best to the police, making it impossible for people to guess the logic of his behavior.

The only constant is the crime time - ten days, every ten days, a bomb will appear in the city.

Except for the eighth bomb that was successfully dismantled, the others exploded, and some people were injured and some died.

This one was in the downtown area, the next one was in the wasteland, the next one was placed in the cemetery, and then it was placed in front of the school...

The police were very passive. They followed the murderer and searched everywhere, but they never caught the mysterious murderer.

Xisha's crime pattern is constantly changing, he does not conform to the common sense in criminal psychology, he has no established goal, no complete logical chain, like an unpredictable variable, like a bug in the city.

What went wrong?

Su Hui took a deep breath and began to look at the photos in detail.

There must be some rules, he must find the logic from these intricate data, so as to prevent the next disaster from happening.

He was watching when the computer suddenly beeped.

Su Hui raised his head and saw that it was an unfamiliar account, and it was sent from the inside, but he couldn't see the other party's account clearly.

"poet."

The other party typed his name directly.

Su Hui frowned and replied with a "?"

The other party popped up a sentence: "You can't catch me."

At that moment, Su Hui felt as if a figure was approaching, and before he could see that person's face clearly, a knife was inserted into his body.

The cold sharp blade seemed to freeze the flesh and blood, and then slowly slid down to cut the internal organs, and the severe pain passed through the nerves instantly.

Cold sweat rolled down his forehead, and trembling swept his whole body.

He struggled in pain, trying to give an early warning, but his throat seemed to be choked, and he could only groan in pain.

"Su Hui, Su Hui!" A familiar voice rang in his ears, "Did you have a nightmare?"

Su Hui finally struggled out of that dream. He sat up and pulled off the blindfold, like a suffocating person suddenly able to breathe freely. He took in the air greedily, and then coughed repeatedly.

Su Hui unconsciously covered his abdomen. Naturally, there was no murder weapon there, and the wound from two years ago had already healed.But the feeling just now was too real.

The hair on his forehead was already soaked in cold sweat. In the confusion, Su Hui seemed to see some afterimages, but he couldn't remember the specific details.That dream seemed to be broken into pieces, which made him unable to trace the logic carefully.

Then he remembered that that was the last call he made to his mother, and since then, he had never had the chance to see her again, and he hadn't been able to give away the set of purple clay pots.

He suddenly felt a pain in his chest, and he tightly grasped the quilt in front of him with his ten fingers.

For a long time, Su Hui was indifferent to everything around him, but as he was pulled back to the human world bit by bit recently, those emotions that had been wrapped up all this time suddenly came out.

For a moment he felt himself overwhelmed by the sadness, trembling uncontrollably from his fingertips to his body.

Lu Junchi sat by his bed, stroked his back lightly, and when he gradually recovered from his panic, he wiped away the tears from the corners of his eyes, and his eyes returned to clarity.

He handed him a glass of warm water, and Su Hui took it and drank a couple of sips. He sat for a while before feeling better, and asked hoarsely, "What time is it?"

Lu Junchi checked his phone: "Seven o'clock." This was earlier than Su Hui's usual wake-up time.

When Su Hui woke up, he found that Lu Jun was ready for breakfast sooner or later.

Today's breakfast is a bit special. It is a pocket bread slice bought from a convenience store, filled with egg yolks and salad dressing.

Lu Jun ran over to buy it sooner or later.

Su Hui saw the pocket bread on the plate on the table at a glance, picked it up and took a bite.

Lu Junchi asked from the side, "Do you like it?"

Su Hui narrowed his eyes and said, "Well, it's delicious. I really like this kind of mayonnaise."

Mayonnaise with egg yolk has a fresh aroma, delicate taste, and tastes full of memories. After moving to the Chinese police, the nearby convenience stores are far away. It seems that he has not eaten this for a long time. .

The delicious food eased the effects of the nightmare, and he gradually felt better.

Lu Junchi still remembered that this was the breakfast that the poet liked to eat in the past.

He deliberately bought this today, just to prove it.

Human behavior is easy to change, but these small habits and preferences in life are hard to change.

Lu Junchi looked at Su Hui, hoping to see something in his expression.

Su Hui's face was as white as fine jade, he lowered his head to eat the salad egg yolk bun, his long eyelashes drooped, there was a sense of fragility in his appearance, like porcelain that would break if touched, but There is also a kind of tenacity and forbearance in the eyebrows.

For a moment, Lu Junchi felt that Su Hui's soul and ability seemed to be sealed, sealed in this weak-looking body, dragged down by the mortal world.

He has seen that when he went all out, all the problems seemed to be solved in front of him, how radiant and fascinating he was at that time.

Su Hui was watched by Lu Junchi, thinking that something was on the corner of his mouth, so he took out a tissue and wiped it off.Finding nothing, I picked up the second one.

There was no clue about the change in expression, Lu Junchi just saw that Su Hui really liked this food, he pushed the plate towards Su Hui, and turned to eat other breakfasts.

He pretended to be casual and asked Su Hui: "At Doctor Huang's side before, he asked about your old injury. When did that happen?"

Su replied, "Two years ago, it was an accident."

Lu Junchi asked: "The specific situation is..."

Su Hui paused, apparently he didn't want to mention it, he said lightly: "It's all in the past anyway."

After finishing the second egg yolk bun, Su Hui stuck out his tongue and licked the corner of his mouth, then picked up the third...

Hemingway seemed to have smelled it, and boldly jumped onto the table, meowing.

Su Hui hid for a while, and reasoned with it seriously: "Little cats can't eat this."

He stuffed the last bite of bread into his mouth, stretched out his other hand, and gently rubbed Maomao's head.

Hemingway felt that he was robbed of food by his master, and he was a little bit unwilling, so he let out a meowing sound.

The topic quickly drifted away, and the first cautious trial did not yield any clear clues.

When he was about to leave, Su Hui saw a small box on the table, picked it up and looked at it. "It should be a new puzzle piece."

There is no time to disassemble it now, it seems that we can only go back and open it again.

Lu Junchi asked casually, "This box doesn't look big." Recently, he has gotten used to Su Hui occasionally buying some complicated jigsaw puzzles overseas, but this box of jigsaw puzzles seems too small.

Su replied: "This is JigsawPuzzle29, there are only 29 pieces in total, ten levels of difficulty."

Lu Junchi: "How many levels of difficulty are there in the puzzle?"

"Level ten." Su Hui said while putting on his shoes, "But I don't think it will be worthy of the name. The big puzzles are about discipline, meticulousness and patience, while the small ones mainly test the thinking of solving problems."

Today is the beginning of the month, Bureau Tan held a regular meeting with several captains of the criminal investigation team.

The old bureau chief drank the wolfberry water in the thermos and finished listening to the reports of each group.

Lu Junchi didn't know if it was his own illusion, he felt that there seemed to be a dark cloud in Tan Ju's brow.

Sure enough, after the meeting, Director Tan said: "Yesterday, the Fourth Sub-bureau received an alarm. Someone placed a time bomb on the bus. Fortunately, it was discovered in time. The special police sent people to participate in the EOD. According to the equivalent calculation, If the bomb detonates, there may be accidents for many people in the car."

The criminal investigation team has not received a detailed report on this matter. When they heard about it at this time, they all looked at each other in blank dismay.

There has been no bomber in Huadu for nearly two years. I don't know whose head this job will fall on.

There are not many bombings in the city, but they happen every few years.

Most of the bombs are simple, common, even earthy, some are materials taken from fireworks fields, and some are just chemical spills.

This type of case is relatively routine and relatively easy to handle.

And this kind of timing... high-end means that the murderer has certain professional skills and will consciously evade and hide his identity.

The related cases are not like ordinary criminal cases. There are many clues to investigate. In the bombing case, there are very few fingerprints and traces left behind. The scene after the explosion was even more chaotic.

This kind of case is uncontrollable, and the casualties will be more serious than ordinary cases.

Sometimes it even threatens the lives of police officers.

Among other things, the fine sand case two years ago was a nightmare for the police in Huadu.

This thing came out again this year, and everyone was sweating, and some kept their heads down, as if they were afraid of receiving this case.

When Lu Junchi heard this, he looked up at Ju Tan.

If this case is related to the Xisha case, he would like to take the initiative.

But Director Tan avoided his gaze, raised his head and said, "Xing Yunhai, you should set up a task force based on the fifth team. This time, you must pay attention to safety and cooperate with the special police EOD team."

Xing Yunhai bowed his head and said, "Okay."
