Criminal Investigation Notes

Huadu, after nine o'clock in the evening, it was a calm and ordinary night, and the whole world was quiet.

The street lamps next to the street are lit one by one, and the colorful neon on the street outlines a beautiful night view of the city.

Autumn in Huadu is very short, and it seems that it will not be long before winter begins.

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 quarrel and unhappiness disappeared.

The car was very empty all of a sudden. Not to mention that everyone had a seat, there were still 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: "Ah? Whose is this bag?"

He found the bag under the seat next to him. The bag was black. In the dark night, if you didn't look carefully, you couldn't find it at all. The middle-aged man picked up the bag and felt a little heavy.

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

The middle-aged man walked forward with a bag strangely, and said to the driver, "Master, someone left the bag on the car."

The driver was still driving and shouted for help, "Whose bag is it?"

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 here."

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

No one responded, and the 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? Give him the main station?"

"How can I forget such a big bag? It's not intentional to put it here!"

"Is there anything missing in this car? The driver is not surprised."

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

The car suddenly fell silent, and everyone fell silent.

Sure enough, a strange sound came from the bag, it was a soft beep, like the sound of an electronic alarm clock.

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

Hearing this sentence, the face of the person in the car changed, and the middle-aged man opened the zipper of the bag with a cluck.

Inside the bag is 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 the dream was so real, as if it had actually happened.

Su Hui was a little unclear for a while, 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 has dreams, and after he wakes up, he can't remember many details of the dreams.

"...I see, Mom, I'll go back on the weekend, ah, I said I've made friends, so you don't have to give me a blind date."

"What? Take it home for you to see? It's a bit too fast, you have to consider the other party's feelings, right?"

There was her mother's voice on the other end of the phone, and she asked cautiously, "Then... how does she look? Does she have a good temper?"

In the dream, Su Hui responded casually, and then said, "Mom, you have to believe in your son's vision. He is good-looking, virtuous, and very gentle. Well, there's nothing wrong with Dink's not wanting to have children..."

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

Su Hui advised her: "In fact, if you want to experience the pleasure of developing, isn't it better to have a cat?"

Mom snorted: "Well, if I had a cat back then, I wouldn't be so eloquent at me."

Su Hui hurriedly went to coax her: "Mom, I bought a tea set made of purple sand for you recently. I'm going to bring it back next time."

Hearing this, my old mother immediately smiled and said to let him take a picture to see it.

Su Hui asked sourly, "Can cats do it?"

Mom shook hands and said: "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, the rest will be placed in the back. My dad and I are not afraid that you are too much in peacetime. Too lazy, are you afraid that you will not be able to take care of yourself? You can find another similar cat, and the family will starve each other? "

Over there, my mother nagged something again. Su Hui hung up the phone and walked down the corridor of Building 3. When he came to the corner, he saw a man in overalls squatting in front of the generally unmanned vending machine.

Su Hui: "..."

Worker:"……"

Su Hui asked the worker, "Did you see anything else inside?"

The worker was stunned for a moment: "You mean this..." As he spoke, he handed over a lunch box, "I also said that this machine is almost full of beverages, but there was a lunch box at the outlet. I just now Still thinking, our vending machine is so smart."

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

He went upstairs, put the bento box in the 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 into a star and placed it beside the lunch box.

The phone beeps: "I brought you chicken soup today, have you received it?"

The corners of Su Hui's mouth rose unconsciously: "If I'm five minutes later, I'll probably be taken away by the vending machine repairer."

After a while, the other party replied, "I'm sorry, I'll pay attention next time."

"I don't blame you, did you get 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: "This time the stars will be given to you together with the next lunch box."

"I already have ninety-nine stars. If you add this one, you can make up the whole thing."

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

Immediately, the other party replied: "Okay!"

Su Hui turned on the computer, entered the password to log in to the system, and popped up a document to be checked.

fine sand again...

He opened the file, which contained the latest explosion. Two people were killed and two people were injured. This was the eighth victim of the fine sand explosion.

For several months in a row, more than a dozen crimes have been committed, and this mysterious fine sand is simply haunted.

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

Originally, the name "fine sand" originated from some sand particles found at the scene of the explosion. This explosive was self-made and isolated with a sand layer. When it exploded, some colored fine sand particles were left on the scene. 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 do everything possible to the police, making it impossible to guess the logic of his behavior.

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

Except for the eighth one that was successfully dismantled, the others all exploded, and some 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 later it was placed in front of the school...

The police were very passive. They ran around with 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 goals and no complete logical chain. He is like an unpredictable variable, like a bug in the city.

Where is the problem?

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

There must be some rules, and he must find the logic in these intricate materials, so that the next disaster can be prevented.

He was watching when the computer suddenly beeped.

Su Hui looked up 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.

"poet."

The other party typed his name directly.

Su Hui frowned and replied "?"

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

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

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

Cold sweat ran down his forehead, and trembling swept his body.

He struggled in pain, trying to issue an early warning, but his throat seemed to be strangled, and he could only murmur in pain.

"Su Hui, Su Hui!" A familiar voice sounded in his ears, "Have you had a nightmare?"

Su Hui finally struggled out of that dream. He sat up and pulled off the blindfold. It was like a suffocated person who was suddenly able to breathe freely.

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, making it impossible for him to carefully pursue its logic.

Then he remembered that it was the last call he made to his mother, and since then, he never had a chance to see her again, and he failed to give away the set of purple clay pots.

He suddenly felt a pain in his chest, and his fingers clung to the bedding in front of him.

Su Hui had been indifferent to everything around him for a long time, but as he was pulled back to the world bit by bit recently, the emotions that had been wrapped up suddenly poured out.

For a moment he felt himself overwhelmed by the grief, shaking uncontrollably from the tips of his fingers to his body.

Lu Junchi sat beside his bed and gently stroked his back. When he gradually recovered from the panic, he wiped 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 took two sips. After sitting for a while, he felt better and asked in a hoarse voice, "What time is it?"

Lu Jun turned over his phone late: "Seven o'clock." This is a little earlier than the usual time for Su Hui to get up.

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

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

Lu Jun ran over to buy it in the morning.

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

Lu Junchi asked aside, "Do you like it?"

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

The mayonnaise with egg yolk has the fresh aroma and delicate taste. It tastes full of the taste in memory. After moving to Huajing, the nearby convenience stores are far away. It seems that he has not eaten this for a long time. .

The delicious food soothed the effects of the nightmare, and he gradually felt a lot better.

Lu Junchi still remembered that this was the breakfast that the poet used to like very much.

He deliberately bought this today, just to prove it.

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

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

Su Hui's face was as white as a fine jade. He lowered his head and ate a salad egg yolk bun. His long eyelashes drooped down. There was a sense of fragility in his appearance, like china that would shatter when touched, but There is 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 seemingly sick body, dragged down by the mortal world.

He's seen how radiant and mesmerizing he was when he gave his all, and all the problems seemed to be solved in front of him.

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

There was no clue from the change in his 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 inadvertently asked Su Hui: "I was at Dr. Huang's side before, and he asked about your old injury. When did it happen?"

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

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

Su Hui's actions stopped, and it seemed that he didn't want to mention it. He said lightly: "It's all in the past anyway."

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

Hemingway seemed to smell it and jumped up on the table boldly, meowing.

Su Hui ducked for a while and reasoned with it seriously: "Kitty can't eat this."

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

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

The topic quickly drifted away, and the first cautious trial did not get 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."

There is no time to disassemble it now, it seems to have to turn around and open it again.

Lu Junchi asked casually, "This box doesn't look very big." Recently, he has become accustomed to Su Hui occasionally buying some complicated puzzles from overseas, but this box of puzzles looks too small.

Su Hui said: "This is JigsawPuzzle29, there are only 29 pieces in total, and the difficulty level is ten."

Lu Junchi: "How difficult is the puzzle?"

"Level 10." 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 regularity and meticulousness and patience. The small puzzles mainly test the problem-solving ideas."

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

The old director drank the wolfberry water in the thermos cup and listened to the reports of each group.

Lu Junchi didn't know if it was his own delusion. He felt that there seemed to be a dark cloud in Bureau Tan's eyebrows.

Sure enough, after the meeting, Bureau Tan said: "Yesterday, the Fourth Bureau received an alarm. Someone placed a time bomb on the bus. Fortunately, it was found in time. If the bomb detonated, many people in the car could be in danger."

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

Huadu has not had a bomber for nearly two years, and I don't know who will fall on this errand.

There aren't many bombings in the city, but they do happen every few years.

Most of the bombs are simple, ordinary, or even earthy, some are materials taken from the fireworks field, and some are chemical effluents.

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

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

Relevant cases are not like ordinary criminal cases. There are many clues to investigate. There are few fingerprints in explosion cases, and traces are left behind. The scene after the explosion is 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.

If nothing else, the Xisha case two years ago was a nightmare for the Huadu police.

This year, this thing came out again. Everyone was sweating, and some people kept their heads down. It seemed that they were afraid of receiving this case.

Lu Junchi heard this and looked up at Bureau Tan.

If this case is related to the Xisha case, he wants to take the initiative to follow up.

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

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