I asked you to write a book, but I didn’t ask you to reveal your criminal record!

"Why are you looking at me like this?"

Lin Chuan noticed the subtle looks in Shen Qianqian and Hu Daqiang's eyes, frowned slightly, and asked.

Shen Qianqian frowned slightly and looked at Lin Chuan intently: "Lin Chuan, I'm a little curious, how do you know this?"

Lin Chuan's face darkened, and he said quibly: "I found out what I learned from the information in order to write a novel. Do you believe it?"

"Believe..."

Shen Qianqian opened her small mouth, with an uncertain look on her face.

It would be strange to believe this answer.

Too abstract!

Lin Chuan sighed slightly, I helped you investigate the case, but you always doubted that my knowledge came from the right source.

Ahem, although it does come from a wrong place.

But that is a virtual world. In the real world, I am still a good and law-abiding citizen.

That’s all.

For the sake of 'all true fans', let's continue investigating the case.

"Do we still need to continue the investigation here?"

Hu Daqiang looked at Lin Chuan, and his current tone was obviously asking for Lin Chuan's opinion.

"Let's go to the second floor." Lin Chuan smiled.

Lin Chuan already knew the scene on the fourth floor.

In his eyes, the murderer's method of forging the scene was a bit clumsy.

2nd floor, Hengli Gym.

The three men, also wearing shoe covers and gloves, crossed the cordon.

In the gym, all kinds of fitness equipment are neatly arranged, but it is a bit stuffy because there are no windows.

Among them, there are not many traces of the scene.

Shen Qianqian took out more than ten photos, which were the blood stain reactions detected by the luminol reagent.

Lin Chuan took the photos and compared them one by one with the scene.

After a while.

Lin Chuan came to the conclusion: "This is indeed not the first scene of the murder."

Shen Qianqian and Hu Daqiang's pupils suddenly trembled.

Hu Daqiang, in particular, frowned with a look of confusion on his face: "Comrade Lin Chuan, after judging that the fourth floor was not the first scene, we immediately launched a search, and the DNA of the deceased was extracted here. This is not the first scene either. ?”

Fortunately for Shen Qianqian, she had heard this speculation from Lin Chuan's mouth, but seeing Lin Chuan's determination, she couldn't help but ask: "How do you determine that this is not the first scene?"

Lin Chuan smiled.

Then, he took out a photo, which was a top-down shot. It captured the blood stain reaction of the luminol reagent on the entire scene, which was full of blue-green fluorescence.

Lin Chuan pointed at the photo and said, "Look at this photo, what shape is the blood stain reaction distributed in?"

Shen Qianqian tilted her head, leaning slightly towards Lin Chuan, and looked at the photo seriously: "The blood stains are distributed in an irregular oval shape."

"Is there any problem with this?" Hu Daqiang also asked with a frown.

Lin Chuan smiled: "Friends who love others all know that blood will still flow after it flows out of the human body. If it is on a flat ground, it will overflow in all directions and form a pool of blood."

Hu Daqiang nodded.

Years of experience as a criminal police officer, it is true that as Lin Chuan said, the blood flowing out of the human body will form a pool of blood on the flat ground.

However, this is consistent with the irregular oval blood stain response map in the gym.

Why did Lin Chuan say this was not the first scene?

Shen Qianqian also looked at Lin Chuan doubtfully.

Lin Chuan pondered for a moment and explained: "Look here, this piece of ground has a slight slope. You can't tell it if you don't feel it carefully. In other words, if the deceased really died here, her blood would pass through this When the blood hits the ground, it will flow in a linear pattern, instead of remaining in an irregular oval-shaped pool of blood like the flat ground. "

Shen Qianqian knelt down, gently touched the ground through her gloves, and brushed it gently.

really.

There is a slight tilt!

Shen Qianqian was still a young detective. She was looking at Lin Chuan with doubts and a bit of surprise in her eyes.

Lin Chuan's survey experience is a bit scary.

Or is it true that he often stalks people and has special research on the blood flow of the deceased?

If this is the case, how many people will he love?

Perverted lover?

Shen Qianqian shook her head and quickly gave up this terrible idea.

Hu Daqiang also swallowed.

The waves behind the Yangtze River push the waves ahead. Lin Chuan's inference almost made him, an old detective, face red.

The case that lasted thirteen years was in vain!

On the other hand, look at Lin Chuan.

He is so meticulous that even a piece of ground has a slight inclination, and he has a thorough understanding of the blood flow.

Hu Daqiang completely put away his contempt and asked for advice seriously: "Comrade Xiaolin, your inference is very reasonable. Since this is not the first scene, then where will the first scene be?"

The first scene is crucial to solving the case.

He never thought that the murderer would be so cunning, fabricating two scenes in succession to confuse the police and mislead the direction of the investigation.

Lin Chuan smiled: "I believe you have already guessed that the deceased was 165cm tall and weighed about 60kg. The murderer moved the deceased to the fake scene, not too far from the original scene."

Shen Qianqian nodded: "Yes."

"But since he had time to fake two scenes in succession, it means that he had enough time to destroy the first scene." Lin Chuan said.

Shen and Hu's expressions suddenly became serious.

Hu Daqiang frowned: "In other words, the clue has been broken again?"

Lin Chuan shook his head and said with a smile: "If we can't find any evidence from these two scenes, we can investigate in another direction, right?"

"What direction?"

Hu Daqiang's thoughts have begun to follow Lin Chuan's.

"Suppose you are the murderer. Imagine that you are a murderer who needs to fake two scenes and clean up the first scene. What would you need?" Lin Chuan said with a smile.

Hu Daqiang was indeed a seasoned detective. He immediately understood Lin Chuan's thoughts and his eyes lit up: "You mean, a tool?"

To clean up the scene, you must have tools.

Especially to clean blood stains, disinfectant, luminol reagent, or bleach may be used.

These are not enough.

You also need towels to absorb blood, buckets with water, mops for wiping the floor, etc.

"right."

Lin Chuan nodded, said seriously, and turned into a detective, "Based on the existing clues, I infer that his method of forging the scene was not professional. Let's assume the identity of the murderer."

"In the first step, after the murderer killed the deceased with a dumbbell, he began to clean up her traces, carried or carried her to Hengli Company on the fourth floor, and then faked the first scene in Hengli Company."

"The second step is to return to the scene, collect blood, enter the Hengli Gym with the murder weapon dumbbells, and fake a second scene."

"The third step is to start cleaning up the original crime scene."

"This is also the most critical step. It is best to use towels and paper towels to absorb the blood first, because if washed with water, the blood will spread over a large area, and the blood stains cannot be completely removed, and the reaction of the luminol reagent cannot be avoided."

"Then, start using disinfectant or..."

"The last step is to deal with the cleaning tools."

"If he were stupid, he would take all the tools away."

"But there are high-definition cameras monitoring the elevators, underground parking lots, and outside the streets. It is easy to be spotted with tools. So, if he is smarter, he will hide these tools in the Hengli Building, in a place he thinks is safe. Location."

"And this location should be on the fifth floor."

"Because the fourth and second floors are fake sites. The purpose is to let the police focus on the fourth floor and below."

"The real crime scene is most likely the warehouse on the fifth floor."

hiss!

After hearing this, Shen Qianqian took a deep breath and looked at Lin Chuan intently.

This step is so clear!

"Officer Shen, I'm just stepping into the perspective of the suspect. Don't look at me like that. Novel authors write books about a sense of substitution, and the same goes for reasoning."

Lin Chuan noticed Shen Qianqian's eyes and immediately explained.

For fear of being afraid, Shen Qianqian took out the silver handcuffs and put them on her hands with a snap.

Take away!
