Hayden sat in a chair at the police station, his right leg constantly upside down. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info His right hand was clutching a soccer ball, and there was still dirt on it.

Hayden was called back by his mother during training, and when he left the training ground, they drove to the police station, and then his mother went to take notes.

The police station was busy, and Hayden looked up and saw all the busy figures.

Hayden was a little bored and a little nervous, he didn't know why he came to the police station, but, looking at his mother's emotions, it was obviously not a trivial matter.

This reminded Hayden of the last time he came to the police station, it was ten years ago, when his father encountered a burglary at home, and after a fight, he was stabbed to death by a kitchen knife, and the family had to take a police car to the police station on a cold winter day.

Hayden suddenly remembered that that time, he seemed to be playing football and was called out.

He couldn't remember if he was holding the soccer ball at the time, but the connection between the soccer ball and the police department still made Hayden hate it.

As if his hands had been burned, Hayden suddenly threw the football out.

"Hey, don't play football in the office. The policeman, who was busy behind his desk, looked up and shouted, he was too busy to educate teenagers, stretched out his foot and pulled the football under his desk, and continued to work.

Hayden didn't want the soccer ball anymore, so he stood up and looked blankly at both sides, and he didn't dare to leave, so he stood on the balcony to blow the wind.

There were already a few policemen smoking on the balcony, and they saw that Hayden was not from any background, and each took out his own cigarette and lit it without saying a word.

This is the culture of the Swedes, where smokers smoke together, but they don't have to talk, and they always smoke their own cigarettes, rarely handing them over, not even lending lighters, and not lighting cigarettes for others.

Hayden stood in the cold wind with his arms crossed to cool his emotions.

I don't know how long it took, the balcony door opened and closed, and suddenly a voice came out: "Hayden...... Hayden!"

"Mom?" Hayden stepped out of the balcony to see his agitated mother.

"Hayden, come here. "There were some signs of makeup on my mother's cheeks that had been diluted, and it was obvious that she had cried.

Hayden was startled, hurriedly ran over, and asked, "Is something wrong?"

"Your father's killer has been found. The mother grabbed her son's shoulder and began to cry.

The surrounding policemen heard the voice, and they just glanced back and didn't say anything, in the past two days, they have seen a lot of similar situations.

Hayden froze, his lips were so dry, and his throat tightened, "Who is it?"

"I'll let the officer tell you. The mother shook her head and walked forward with her son in her arms.

Hayden was 17 years old, and his broad-shouldered mother couldn't hold him at all, but his steps were stumbling and almost falling.

"Officer Fox, this is my son. The mother sat down with her son and said, "Please tell him about his father's situation." ”

"Of course. Fox looked down at the file and said, "Hayden, can I call you Hayden?"

"Yes. Hayden looked at the dignified officer, who had no spirit.

Fox nodded and said, "Hayden, our Stockholm Police Department currently has a new technology called PCR, I don't know if you've heard of it?"

Hayden shook his head.

"He spends most of his time playing football," his mother said. ”

Fox nodded and said, "PCR is a means to identify DNA, DNA is a genetic factor that everyone has in their body, in short, if we can get a cell, we can determine whether this cell belongs to you or not." In addition, the current technology is able to examine cells that have been in existence for a long time......"

Hayden was a clever boy, and he immediately came to his senses and shouted, "My father's ring, his ring, Mommy...... Dad had beaten the murderer, and his ring had the murderer's blood stains. ”

"I know, I know. The mother hurriedly reassured her son and said, "I already handed over the ring to the police a few days ago. When I was watching the news on TV before, I saw the Malle case and thought about it. ”

When the burglary happened that year, my father resisted as much as he could, and he hit the other party with his right hand with the ring, and probably broke the other party's face, perhaps because of the hurry, or because the murderer did not see the value of the graduation ring, and did not take it away.

The mother then put the ring away and did not wash it, giving the police an opportunity to collect DNA evidence on it.

The mother explained, but there was no relaxed expression on her face.

Hayden didn't pay much attention, then turned to the police and said, "You found the murderer, didn't you?

"Hayden, you listen to the officer first. His mother stopped him and handed him a glass of water.

The police officer waited for Hayden's mood to calm down a bit, and said, "Hayden, according to your mother's request, I want to give you a detailed explanation of our case-handling process." ”

"Good...... Good. Hayden was stunned by the officer's solemnity.

The officer coughed, looked down at the file again, and said, "Hayden, I'm going to tell you a little bit about PCR technology first." The first point is that PCR can't directly find the murderer, he can only compare whether the two DNA are consistent or related, just like fingerprints, we can compare the fingerprints left at the scene, and the fingerprints of the suspect, if they are consistent, we know that we have caught someone, if it is inconsistent, we know that we have caught the wrong person, but we don't know who is right. ”

"Didn't you catch the murderer?" Hayden didn't understand.

"Listen to me in detail. The officer looked up into Hayden's eyes and said, "Hayden, we don't have a lot of DNA information that we can use for comparison at the moment, so in the first comparison, we didn't find a clear suspect." ”

Hayden's face was suspicious.

"But we did find something. The officer coughed and said, "Do you remember what I just said? PCR can be used to compare whether two DNA pieces are the same or related?"

"Yes. ”

"After comparing the blood stains on the ring, we did find a situation...... Well, we found that the DNA on the ring bears some resemblance to the DNA on the bloody garment left behind by your father. ”

The police officer had said that the mother was watching her son closely.

"What does that mean?" Hayden instinctively felt that this was not good news.

The officer sighed and said, "The DNA on the ring belongs to your father's half-brother." ”

"Uncle Nelson?" exclaimed. His father had only one brother, and only one half-brother, who was taken by his grandfather's wife who married after the divorce, and the two families still corresponded with each other and moved around quite frequently.

"It's not determined yet, our colleagues are investigating. Someone has already gone to ask Mr. Nelson to come to the police station. The officer replied in a low voice.

For him, such a case is not surprising, and the two brothers have a dirty affair, so that one dies and the other fakes it as a burglary, which seems easier to understand in the era of better law and order.

The only thing that is not easy to understand is that PCR can determine the brotherhood between the murderer and the deceased. It took a while for the police officer to reluctantly accept this fact, and as for the principle or something, he didn't know very well.

Hayden's mother and son hugged each other and wept bitterly. The emotions hidden in the chest, once vented, are like a lake blocked by a dam, and it is difficult to stop.

The policeman stood up slightly, did not speak, and simply left the two men in the inner room.

He has more work to do today.

The police throughout Stockholm have a lot to do today.
