Please don't stick to Officer Qi [criminal investigation]

The house is completely enclosed, except for the trace of Qi Lin breaking into the door, there is no trace of fighting, nor any trace of rummaging. It seems that killing people for money should not be the case.

The floor was also clean, the marble slabs had been polished to a gleaming shine, and only a small patch of floor was stained by the blood that had flowed down.There was a knife next to the coffee table. After DNA comparison, this knife was the murder weapon.

"The murderer was very strict and didn't leave any fingerprint information. It seems that the crime was premeditated, and the murderer should be someone he knew." Qi Lin analyzed the information brought by Xiao Wang from the Criminal Investigation Department, "What is the time of death?"

"The time has not been analyzed yet, and further derivation is needed," Xiao Wang said. "A certain dose of embalming was applied to the body, which greatly interfered with the state of the body. timeline to deduce step by step."

"What type of embalming?"

"Probably food additives. This kind of antiseptic effect is not very great, and the interference is limited. It can be defined after further forensic examination. Based on the situation of the corpse spots, we can roughly infer that it should have been dead for more than ten hours."

Qi Lin looked at his watch, it was 08:30, which meant that the deceased died around ten o'clock last night.

"He died around ten o'clock, but the murderer left the room very late." Qi Lin's eyes fell on the roses on the porch.

It was a pale pink rose in an unknown mineral water bottle.The roses bloomed brightly, and there was still freshly picked dew on them.

"Maybe I watered it before I left." Xiao Wang replied, "We will continue to investigate and let you know when there is something."

Qi Lin responded, and then asked, "Shi Le hasn't come back yet?"

An hour ago, Qi Lin couldn't bear Shi Le's begging, so he agreed to let Shi Le look at the corpse, but after just one glance, Shi Le vomited out this morning's breakfast and yesterday's dinner.

Really not wanting him to spoil the scene, Qi Lin sent Shi Le downstairs to rest and let him take a good rest.It has been an hour now, and it seems that I have not recovered.

That's right, no one can bear to see such a bloody scene in the first case.

Xiao Wang didn't know, so Qi Lin went to the balcony to look down.When she lowered her head, Shi Le was sitting on a bench in the community park, her warm brown hair shining brightly in the sun.

"Shile!" Qi Lin shouted downstairs.Because it was too far away, Shi Le didn't hear it.

"I have his phone number, do you want to call him up?" Xiao Wang, who was searching for evidence, heard Qi Lin's yell and asked.

"Call it," Qi Lin said, but then he vetoed his own idea, "Forget it, I'll go down by myself."

Shi Le sat in a very conspicuous position, and Qi Lin saw him through the glass door as soon as he got out of the elevator.His expression was not very good-looking, the corners of his mouth were drooping down, and there seemed to be some fear in his eyes.

Qi Lin didn't rush over, but took out his mobile phone from his pocket first, and bought two bottles of instant coffee from the vending machine in the lobby on the first floor.One bottle was in his pocket, and the other bottle was pulled open and handed to Shi Le.

"Afraid?"

Shi Le raised his head, and his light blue pupils were covered with dark clouds.The boy was obviously afraid of talking but he was very stubborn, "No, this little scene can still be seen."

Qi Lin laughed twice, "It's good to see you, there will be worse cases waiting for you in the future."

"Really?" Shi Le's tone trembled obviously.

Qi Lin was finally amused by the boy.

"Haha, I'm kidding you." He took a sip of coffee, and the cold and bitter taste spread to the whole piece of taste, "This time you are unlucky, and you happened to encounter such a tragic case. If it is normal, it will not last for a long, long time." There will be a criminal case. You are still a newcomer, so you don't need to participate in this case, and I will send you back later."

The boy next to him didn't speak for a long time.After a while, he followed Qi Lin's example and took a sip of coffee, then frowned bitterly, "Senior, I won't leave, I want to participate in this case."

Teenagers are always stubborn.Qi Lin couldn't help but look at Shi Le a few more times.

"Senior! Believe me, I can do it." It was these few glances that made Shi Le feel a little edgy. He looked excited, eager to prove himself to Qi Lin.

Qi Lin shrugged, but he didn't trust the newcomer in his heart.

Doesn't look like a reliable partner by any means.

Even so, he nodded and took out the crumpled death report from his pocket, "Look."

Shi Le took the report, but didn't open it, just held it in his hand.

Little furry child.

Qi Lin raised the corner of his mouth, "Open it, there are no photos inside, don't be afraid."

Only then did Shi Le take a deep breath, as if making a major decision, gently pushed aside a corner of the report, and carefully read the text inside.

"Is this a vendetta?" After reading it, Shi Le pointed to a line of small characters and said: "If there is no trace of flipping, it means that he didn't die because he was looking for a specific item. And the deceased died directly from the wound on his chest, It shows that he was not prepared against the murderer, and was killed directly when facing the murderer head-on."

His analysis was perfect, almost the same as Qi Lin's own analysis.

But for the purpose of testing newcomers, Qi Lin continued to ask; "Then what do you think the murderer has to do with the deceased?"

Shi Le dragged his chin with his hands and thought for a while, "Maybe it's a neighbor? Someone came to him because he was disturbing the people. If he didn't listen, the neighbor killed him."

Qi Lin was noncommittal.

Shi Le continued: "The neighbor knocked on his door. After he opened the door, the neighbor told him to turn off the music. But he didn't care. He turned his head and tried to turn up the music, but the neighbor sneaked into the room and yelled The dead man let out a sound. The dead man turned his head, and the gleaming knife pierced into his chest."

As he was talking, Shi Le stood up and began to perform his own little theater, playing the murderer for a while and the dead for a while, turning around and enjoying himself.

Qi Lin pulled Shi Le back to sit on the bench by pulling his sleeves.

"How about some breakfast first?" he asked.Qi Lin came in a hurry and hadn't been able to have breakfast yet. He just drank a cup of coffee on an empty stomach and his stomach ached.He felt like he was going to be overwhelmed with breakfast.

Shi Le, who performed the small theater, has eased from the shock and terror, and she is much more cheerful.He clapped his hands: "Okay, I vomited up my breakfast, and I'm so hungry now, hurry up and find a family."

So, Qi Lin drove Shi Le to a fish sausage noodle shop located downstairs from the police station.

The boss's movements were swift, and it didn't take long for two servings of noodles overflowing with soup.The white fish meat and brown large intestine lie quietly on the surface, steaming, giving people a warm feeling.

"Look at this intestine, it looks like the one at the scene of the crime, it's really scary." Shi Le stared at the noodles in the bowl without eating.

"Damn," Qi Lin, who had sucked in half a bowl of noodles at the speed of light, bit off the noodles, and tapped Shile's bowl with his chopsticks, "It's time to eat, why are you talking about such things?"

"Isn't this about the case? I thought my seniors would praise me."

"Get out." Qi Lin said angrily.

"But senior, do you think my inference is possible?"

"It's possible, but it's probably not the truth." Qi Lin poured soy sauce on his face, "Are you completely defenseless against your neighbors?"

Shi Le shook her head, "No, but everyone's situation is different, maybe the deceased really didn't have any defense at all."

"But if it's a neighbor, why do you want to slit all the stomach?" Qi Lin pulled out a pair of clean chopsticks from the side and held them in his hands like daggers. "If it was me, I would choose to insert into his stomach, but It’s not all broken from top to bottom.”

Qi Lin gestured in the air.It's strange, according to this theory, it's not just that the neighbors are wrong, no matter who the murderer is, there should be no motive.

Why make such a big wound?

Qi Lin has no clue for now.

The desktop vibrated.He picked up his phone, it was a message from Xiao Wang.

——The monitoring has been called out, and it will be sent to you now.

Followed by several G video files.

The monitoring obtained is the monitoring of the elevator room next to the crime scene. From this angle, both the elevator room and the stairway can be seen.

He pressed the multiplier button, and the video fast forwarded in multiples of sixteen.Finally, the video went black, fell into a brief blank, and then returned to normal.

"This paragraph..." Shi Le also looked at the phone next to Qi Lin.He fiddled with the progress bar twice, returned to the time when the video was not black, and watched this paragraph again.

This time Qi Lin finally saw clearly that it was a black balloon, and someone with ulterior motives somehow used the balloon to block the camera tightly.

The darkness didn't last long, and the balloon was pulled away in just 5 minutes from ten o'clock to ten o'clock five minutes later.

"This should be the time when the crime happened, exactly ten hours from now." Qi Lin continued to fast forward until he watched the entire surveillance.

The surveillance was blacked out three times throughout the night, from 11:30 to [-]:[-], from [-]:[-] to [-]:[-], and from [-]:[-] to [-]:[-] the next morning.

According to Qi Lin's deduction, the first black screen should be the time when the murderer entered the room, and the second black screen should be the time when the murderer left.But in this way, the third black screen is a bit redundant.

"Did the murderer return to the scene once?" Shi Le focused on the murderer's behavior, but Qi Lin focused on how the balloon should be moved to the camera.

After a while, he dialed Xiao Wang's phone.

"Don't check the people around him, the main thing is to check the deceased." Qi Lin said, "The first balloon was moved by the deceased himself."

"What do you mean?" Shi Le looked at Qi Lin.

"I don't know the reason why the deceased did this, but he must have his reasons for doing so." Qi Lin carefully considered his point of view, "The first time the balloon is moved, the deceased should have some other purpose, the purpose is to let others avoid it." Turn on the camera and come to his house."

"Look here." Qi Lin rewound the video to before the first black screen, and a blurry human figure was reflected on the tile opposite the elevator.The man held the remote control of the toy car and controlled the remote control car with a balloon to cover the camera.

Although the picture is very blurry, Shi Le can vaguely tell that this man is the deceased.
