“Ｍerry Ｃhristmas！ ~~~" "Merry Christmas!"

The largest square in S City was brightly lit, and groups of young people were chasing each other and spraying canned compressed strips of color and snow on each other's heads, while screaming and blessing happily.

The air is filled with the sweet and sour smell of spray, and the sound of colorful stripes and mist is everywhere under the reflection of various lights.

Everyone's face was filled with smiles, and everyone's head and body were sprayed with colored stripes of various colors.

Bursts of laughter, screams, and blessings came from all corners, originally small groups were playing with each other, and finally the "flames of war" extended to everyone, and people who didn't know each other were blessing each other and spraying.

Suddenly, the big bell in the square rang loudly, and after twelve rings, the mood of the crowd reached a boiling point, and the colored bars and flying snow covered the space overhead.

Everyone is happily celebrating this festival from the West, time seems to freeze, and only happy emotions are spreading.

In the remote southwest corner of the square, a man seemed to be tired of playing, sitting alone on a bench, looking out of place with the carnival atmosphere around him.

His head was tilted slightly to his shoulders, one hand was on his lap, and a black scarf was wrapped around his wrist as if it were cold, and in the darkness it seemed to be dripping with liquid.

The noisy young people chased after him in twos and threes, and the occasional person who passed by him did not give him a second look.

The night was over, and the excited people slowly dispersed, and only he sat alone, like a cold statue.

At this time, if a careful person passes by, he will find that under the chair where the person is sitting, a large pile of dark red marks has appeared.

The "Ding ~~~~~~" phone rang suddenly, and Yang Zi, who was lying on the table and pretending to sleep, jumped up suddenly, and quickly grabbed the receiver: "Hello, criminal police team."

At the same time, he habitually looked at the clock on the wall, half past five in the morning.

The anxious voice of Director Li of the Square Police Station came from the phone: "Team Yang, a male corpse was found in the square."

When the comrades of the serious case team arrived at the scene, the scene had been protected by colleagues from the police station.

The body was found by a cleaner who was cleaning up, and because he was frightened and a little out of control, he couldn't say anything.

Yang Zi asked the comrades from the police station to bring the cleaner to his car to comfort him first, and Xiaopang and Crow, who had been urgently notified to come back, had already begun to investigate the scene.

The location where the body was found was on a bench in the remote southwest corner of the square, in front of a passageway, and there was a pile of garbage on the road, in which a bloody scalpel was found, which had been collected as evidence.

Because there were so many people here that day, there were footprints everywhere on the road.

Behind the bench is a flower bed, planted with only a few branches due to the winter, but it is still relatively dense and has not left any traces of being trampled.

There was a pool of half-coagulated blood underneath the bench, with marks of being scratched by a broomstick.

The deceased was seated on the right side of the bench, wearing a dark grey down jacket without a hat or gloves.

His left hand rested on his left knee and his right hand hung naturally at his side, and he found no ID card on him, no belongings such as wallets, cell phones and keys, and only a few bits and pieces of money in his pocket.

Yang Zi put on gloves and gently pulled open the scarf wrapped around the corpse's left wrist, and saw a wound on his wrist, which happened to cut the artery, causing excessive blood loss and death.

Judging from the scene, it looked like a suicide, he checked it carefully, and found no more clues, so he took out his mobile phone, dialed Lin Shanshan's phone, and told her that she needed to rush back to the bureau to check the body immediately.

While putting the body in the plastic bag of the shrouded body with the crow, Xiaopang complained in a low voice: "I said that you are a dead crow, and that you crow are really like a crow, good things are not good and bad things are spiritual." That day, Haizi said that he wanted to go on a blind date, you want to talk more, look, you have to be busy again now. ”

"Cut~~. Dead fatty, you don't see this as suicide. Go back and wait for Dr. Lin to examine it, and write a closing report. The crow said disapprovingly.

The two stuffed the body into the car, and Yang Zi waved his hand to let them pull the body back to the bureau first, and asked Lin Shanshan to examine it.

Then he walked to Director Li of the police station, and said as he walked: "Li Tou, you have worked hard. There's nothing going on here, so you can go back with your brothers. I took the cleaner back and asked. I will keep you informed of any situation. ”

At eight o'clock in the morning, at the S City Public Security Bureau, a panicked woman in a cleaner's uniform was sitting in the interrogation room.

Yang Zi first poured her a cup of hot water and put it in front of her, and then opened the inquiry record: "Auntie, don't be afraid, tell me how you found it."

In order not to cause a strong emotional change in the cleaner, Yang Zi did not say the word corpse, but used a "it" to refer to it.

"Me, I'm usually in charge of cleaning the square. It's horrible, I, I've never seen this before. Scared the hell out of me. The cleaner said incoherently.

Yang Zi gently pushed the glass of water in front of her: "Auntie, drink some hot water to warm up your body first." ”

The cleaner's hands were trembling, and then he slowly stretched out and gently held the cup, and after taking a sip, his mood calmed down a little, and then he began to tell the frightened scene just now.

"Usually, I don't start cleaning until half past five. Today, because of Christmas, many people will go to the square to play, and it will get dirty, so I came at half past four. ”

"I came too early, and Aunt Wang, who was in the group with me, hadn't arrived yet, so I started sweeping up first."

"The ground was full of the kind of streamers sprinkled by young people, and I kept sweeping it with my head buried, trying to clean it up quickly."

"Aunt Wang's waist and legs are not good, I think I can sweep more, she can save a little. Sweep all the way to that place. As he spoke, the cleaner suddenly shuddered, and his hands unconsciously clenched the cup in his hand.

"There are sometimes homeless people in the square who spend the night there, but it's always when it's hot."

"So when I saw that person, I thought it was either a homeless man or a drunken man, so I left him alone."

"Just continuing to sweep my floor, I didn't expect him, he, he ...... There's a lot of blood there. ”

Yang Zi recorded in the notebook that when he heard that the cleaner was starting to get nervous again, he raised his head to look at her, comforted her with his eyes, and signaled that she didn't need to be nervous.

The cleaner seemed to feel Yang Zi's comfort, calmed down and continued: "I saw him sitting on the chair, I didn't look closely, and I wanted to sweep him off and walked away. ”

"As I was sweeping, I saw something glowing on the ground, and I swept it over without paying attention."

"Then I saw a dark stain on the ground, and I habitually stretched out my broom and swept it twice, and I felt that something was wrong."

"When I put my head over and looked closely, I felt that it was blood, and when I looked at the person sitting there, I felt that it was a dead man."

"I was so scared that I screamed, maybe it was a little past five o'clock, and there was no one on the street."

"I looked at the shiny thing I had just swept, and it turned out to be a knife that looked like a doctor's use."

"I thought I must have seen a dead man, and I didn't know what to do at the time, but luckily I remembered that I usually said that I would call 110 if there was a situation, so I ran to the phone and called 110. And then they came. ”

After the cleaner finished speaking, Yang Zi looked at the record in his hand and asked her, "Auntie, are you sure you arrived at half past four?" And then until the police came, no one showed up or passed by? ”

"yes, because I'm watching the time go, I must have been there at half past four. Then when it was sweeping the floor, no one came out and no one passed through there. ”

"Well, auntie, thank you for providing us with so much information. Wait a minute, I'll arrange for a comrade to send you back. I will contact you again if necessary. With that, Yang Zi asked Xiaopang to take the cleaner out and arrange a female policeman to send her home.

Yang Zi returned to the office, took out his criminal investigation diary, turned a page, and wrote: Christmas Eve corpse. Male. Murder weapon: scalpel.

Then, Yang Zi wrote two big words under the notebook: "He killed", and also drew a question mark on the side.

After doing all this, he leaned back in his chair, his eyes closed, his fingers tapping unconsciously on the table, and his mind kept thinking about how to start this murder.
