Criminal evidence

In Aaron's home, the police failed to find any valuable clues.

Shen Changyan didn't go in either, he just stood in front of the door in a daze for a long while before opening his mouth again.

"Let someone come over tomorrow to do a blood stain reaction."

If there is a murder, it must be a corpse that needs to be disposed of, so it is impossible for the older person to disappear quietly like this.

When Lu Qinghe followed Shen Changyan downstairs, he could clearly feel the heavy breath emanating from the other person's body.

One case has not been found out yet, the good guy followed the clues and found out the other two.

There are still a lot of people on standby downstairs, and the scene has been cordoned off, and there are some people watching the excitement around, muttering something in their mouths.

"Let's withdraw first." Shen Changyan opened the cordon and said, "Remove the ones below, and keep the ones above."

After speaking, everyone disbanded on the spot.

On the way home, I was still riding a bicycle alone.

But this time, Lu Qinghe didn't go with Shen Changyan, he just followed behind this guy slowly, staring at his figure in a daze.

There are almost no street lights in the small streets and alleys. With the help of the faint light and moonlight from the windows of the surrounding residents, we slowly walk through the road.

The tires rolled over the concrete floor and made a "cuckoo" sound.

When Lu Qinghe was distracted, he suddenly let out an exclamation, and hastily pulled on the brakes, not forgetting to step out and step on the ground.

"Damn you."

He scolded Shen Changyan who stopped the car suddenly. The distance between the front and rear tires of the two sides was less than a finger, and there was almost a "car accident".

Lu Qinghe had lingering fears in his heart. There was a dirty and smelly ditch beside the road, and it would be a disaster if it fell down.

Shen Changyan looked back at him and asked, "What time is it?"

Lu Qinghe subconsciously looked down at his wrist.

"You are sick, I don't have a watch."

Shen Changyan looked down at his own, he said, "It's almost ten o'clock."

After speaking, he didn't intend to continue riding.

Lu Qinghe stood with him for a while, probably knowing why this person was suddenly talking like this, so he spoke up to persuade him.

"Then what, don't be too stressed, this case can't be solved, and it's not your problem alone."

Shen Changyan lowered his head, his eyelashes covered some of his sight, his fingers were long and slender, and when he took out a cigarette from his pocket, he even talked to Lu Qinghe.

"Sorry, it's the last one."

Lu Qinghe pouted, and said, "I don't smoke."

After he paused for a while, he said, "Smoking is harmful to your health, you'd better smoke less."

The lighters were all lit, but after hearing Lu Qinghe's words, Shen Changyan put away the cigarettes again.

Lu Qinghe said, "I know you're feeling uncomfortable, but I can't blame you for this. There are many conditions and restrictions in investigating cases now, and the skills in all aspects are not yet comprehensive. As for the veteran criminal policeman with the longest experience in our bureau, then I dare not say that my detection rate can reach 80.00%.”

Shen Changyan smiled helplessly, and he pushed his bicycle along the road.

"Thank you."

Lu Qinghe also hurriedly pushed the car to catch up with him, "Thank you so much."

"Thank you for comforting me."

"Who comforted you?" Lu Qinghe said, "You really can't blame you for this matter. We all worked hard, no one was passive and sabotage, we were all doing our best, but there are some things that you just don't want to change and work hard. It can be done."

Under the weak light, the figures of the two people were stretched long for a while, shortened for a while, staggered and merged for a while.

Seeing that Shen Changyan didn't answer, Lu Qinghe spoke again.

"Do you think there will be such a statistical database in the future, which will archive the fingerprints and DNA of people all over the country, so that after we get the corpse and extract the remains of the body, we will put it in the statistical database for comparison. The system can automatically help us find the perpetrator."

Lu Qinghe was very interested in mentioning these knowledge and technologies that did not exist yet.

"The identity information is all available, the name, gender, date of birth, and home address are all clear. We no longer have to go around day and night to visit, investigate, jump into cesspit pits and climb house beams, and submit samples directly to technicians. The criminal police are only responsible for arresting people."

The more he spoke, the more refreshing he became, as if he had already achieved such a technical achievement.

Shen Changyan rarely gave Lu Qinghe some reaction.

"The things you said will definitely exist in the future."

Lu Qinghe lowered his head and smiled, "Before you came, the old captain of our criminal investigation team said that I am imaginative and always think about these unrealistic things. I said I can't even think about it?"

"It's really not possible." Shen Changyan poured him a basin of cold water and said, "This is something that other scientific researchers and computer software technicians should consider."

"Why don't you say that you are rigid, do you know that there is a market if there is demand, and any skilled worker is free to consider whether your police need these things. You have to mention it first, and express your ideas and needs. , There must be a docking person to think about whether this thing is realistic or not, and whether it can be made."

Shen Changyan thought about Lu Qinghe's words, and he suddenly nodded.

"You're right. I'll ask Board Director about it later."

"That's right." Lu Qinghe suddenly raised his hand and put it on Shen Changyan's shoulder, he hooked the person to his side, and said, "Even if we don't wait for this thing to be popularized and listed in the future, it will benefit future generations." It’s not bad, at least you have an idea, you don’t want people in the future to investigate the case and wander around like headless chickens like the two of you.”

Shen Changyan was stunned for a moment when their bodies were pressed together suddenly.

Because it is summer, when the weather is the hottest, the materials of the clothes are relatively light and thin.

There are two young and middle-aged men again, and it is inevitable that their bodies will feel a little hot and dry spontaneously.

Shen Changyan and Lu Qinghe knew each other when they were wearing crotch pants earlier, and there was a period of time before when they had no awareness of distance.

But since the first day he knew the gender distinction between boys and girls and realized "sex", he has consciously kept a certain physical distance from everyone.

It was also for this reason that he became estranged from Lu Qinghe inexplicably.

This guy Lu Qinghe didn't like to be clean since he was a child. He rolled all over in mud, hugged a rubber ball, and rubbed on anyone he saw.

Shen Changyan annoyed him a lot later on, after all, as soon as this guy stretched out his hand, a black paw print would be left on his clothes.

But it's much better when I grow up, although the room I live in is still like a doghouse.

The two locked the car downstairs, and the old man in the reception room yelled out another routine when they entered the door.

"Has the case been solved today?"

Lu Qinghe waved his hand and said, "It's not broken, it's so easy to break."

The old man was wearing reading glasses. He looked away from the newspaper and said, "Then you have to hold on tight. Keep working hard tomorrow."

Lu Qinghe was speechless, "This old man."

They went upstairs, greeted each other, and took out their keys to open the door.

Shen Changyan just turned the lock, but after a "click", he suddenly heard Lu Qinghe say again.

"Oh, my quilt hasn't been confiscated yet. Shen Changyan, wait for me. I'll send you the quilt cover in a while. The cotton wool is already folded on my bed. You can get it yourself."

Following a black shadow rushing towards him, Shen Changyan reached out to take it, and the small iron piece in his hand, which was warm, turned out to be the key to Lu Qinghe's room.

When he raised his head again, the person had already run away and disappeared.

Lu Qinghe went upstairs in a hurry, and then went downstairs holding the quilt that had been washed and dried.

Originally, he thought that Shen Changyan would wait in his room, but he didn't expect both doors to be closed tightly.

Lu Qinghe paused and slowed down his pace. He walked slowly, but saw a piece of white paper under the door of his room. On the white paper was an iron key and a sentence.

It says "Give it to you, keep it for use."

Then, with two light strokes, the word "send you" was crossed out.

This series of childish operations was indeed very long-term. After Lu Qinghe collected his things, he didn't bother others anymore. He only met him in the public bathroom early the next morning, so he took the time to ask him.

"Just give me something if you give it to me. Why are you so embarrassed?"

When he said this, Shen Changyan was brushing his teeth.

He glanced sideways at Lu Qinghe, then looked down at the watch on his wrist.

6:15 am.

The co-author specially got up early in the morning and ran to the toilet to "encounter" and then asked the meaning of that sentence.

In fact, it's not very interesting. It was indeed when I helped someone tidy up the closet that day, I really felt that it was too much to let people look down on it.

Shen Changyan spit out the foam in his mouth, and he said, "Have you ever seen someone give away old things?"

Lu Qinghe replied, "So because the bed sheet and quilt cover are old, if you give it to me, it's not considered a gift?"

Shen Changyan nodded, and he said, "Yes."

Lu Qinghe was a little speechless, "Your delivery standards are a little too strict."

Shen Changyan was expressionless. After brushing his teeth, he rolled up the cuffs of his white shirt and washed his face.

"You really want me to give you something?"

He wanted to find someone to make fun of, but after hearing this, Lu Qinghe suddenly became nervous. He retorted, "Who wants something from you, I can't afford it myself."

Shen Changyan said, "Then why are you so obsessed with chasing yesterday's note?"

"Who is confused?"

"The Municipal Bureau goes to work at 08:30. People who have never arrived at the office until 29:[-] will get up at this time today, just to block me in the toilet and ask me why I put the word "send you" Cross it out? "

Lu Qinghe was stunned, he seemed suddenly unable to remember why he was standing here.

Shen Changyan didn't notice the change in his mood, but turned around to leave after washing up.

Lu Qinghe's heart suddenly "thumped" twice, he shouldn't, but he still made a sound from his throat under impulse.

Lu Qinghe asked, "Shen Changyan, do you remember when I first entered junior high school, I invited my classmates to my house for dinner on my birthday?"

Shen Changyan stopped, he turned his head, "I remember."

"Then do you remember that you didn't come?"

"remember."

Lu Qinghe swallowed a mouthful of saliva, "But when I told you before, you promised to come."

There is nothing special about birthdays, just that I can eat a bowl of longevity noodles with poached eggs, and then my mother steamed white noodle steamed buns and fried cabbage with lard, and a large plate of various styles fished out of the jar and put together pickle.

At that time, everyone was very poor, and there was no habit of giving gifts, but...

But Lu Qinghe remembered that when he invited Shen Changyan back then, the other party personally said, "My father brought back a pen from the provincial capital on your birthday. First, when the time comes, he will give it to me, and I will give it to you."

Shen Changyan has always been the oldest, and that year was no exception, he should have received a gift from his father, but Lu Qinghe did not receive it from him.

Not only did he not receive the gift, but he also did not wait for Shen Changyan.

Only after another 13 years, in this place, I heard the other party's words.

"Sorry, forgot."

Answering as expected, Lu Qinghe stood on the spot with his back straight, as if someone had suddenly pulled him hard.

But after all, a 25-year-old man is not hypocritical for a birthday gift that he failed to receive when he was young.

Lu Qinghe stepped forward with a smile, he grabbed Shen Changyan's shoulder and walked out.

"Come on, can you forget? I knew you must be because you got the pen and were reluctant to give it to me, so you didn't come, right, look at you are stingy."

Lu Qinghe said.

"You said you too, can I remember a pen for you? Even if the gift is not available, someone should come."

What's more, I left you the biggest white flour steamed bun, but I didn't give it to Dad when I came home at night, and my mother beat me for nothing, and the steamed bun was also taken away, so you couldn't eat it.

Lu Qinghe said, smiling, eyes full of indifference, the brilliance of the morning fell on his face, and he also hid the last trace of imperceptible regret in his heart.

13 years ago, 13 years later, he still couldn't wait.
