I'm a delivery man, it's reasonable for me to be at the crime scene

Jiang Chen picked the nail on the window of the second room.

With a "pop", it fell down.

Can you get it down so easily?

At the other end of the port, it was quickly loosened and the plank was easily removed.

Is this what the victim nailed?

Did the murderer go out of the door openly?

"Is there any breakthrough?" Wang An asked.

Jiang Chen bit the small flashlight, carefully checked the plank, and said, "The technique is different." "

Wang An frowned: "What do you mean?"

Jiang Chen said: "This plank was not nailed by the victim, but by the murderer. "

"When the murderer finished killing, he went out through the main entrance. "

"For two hours of death, around 9 to 10 o'clock, this is in the countryside, and people in the countryside go to sleep when they arrive. "

"Of course, it is not excluded that there are some people who have not slept. "

"In short, the killer was a level-headed and paranoid personality. "

Wang An listened to his analysis and couldn't help but exclaim.

Jiang Chen speculated in his heart that the murderer wanted to trap the victim, and this room could obviously escape.

But it had to be nailed with wooden boards, including balconies, for fear that it would be improvised.

He stared at every plank.

There's a white plastic thing coming into view.

"Bring me a pair of tweezers. Jiang Chen shouted.

Wang An saw that there was no one here, and just left a trace inspector.

"Oh no, Team Wang, please bring me some tweezers. "Jiang Chen understands the sophistication of human feelings.

I'm afraid that the next second even the auxiliary police will not have to do it.

Wang An smiled: "You kid, what do you have to ask for, I'm afraid I'll eat you?"

I'm afraid, my subordinates order my boss, I'm afraid I'm not looking for a dead rhythm?

Wang An took a pair of tweezers and scotch tape from outside.

Jiang Chen stared at the piece of plastic and fell into deep thought.

"Is it the suspect's stuff?".

"I guess it's got caught in a sharp plank thorn. "

"Something like a glove. "

"It's still two floors. Jiang Chen picked up the plastic.

Wang An asked, "You mean the murderer wore two layers of gloves?"

"Well, I'm not sure which finger it is, but there should be fingerprints on it. Jiang Chen speculated.

The murderer is so cautious, if he wants to kill someone, he should be deployed early.

Wang An said: "First bring all the evidence back to the police station and immediately launch an investigation." "

Jiang Chen asked, "What kind of person is the victim Chang Youwei? Did you find anything in the neighbor investigation?"

At this time, Xiao Luo walked over with the investigation record.

"I have investigated the reputation of the deceased, who was of poor character, often sold fakes to his neighbors, and even had conflicts with business partners. "

He took out another piece of information and said, "This is a common record of going to the police station for getting into trouble with business partners." "

Jiang Chen said: "Immediately check if there are people around him who are in conflict." "

He added slowly: "Does Chang Youwei also have gout?"

Xiao Luo was surprised and asked, "How do you know?"

He took out an examination report, "This is what I found in the bedroom on the first floor where he lived, and the deceased had been suffering from gout for a year. "

Jiang Chen's face was calm.

Like the previous victim, he had gout.

From the moment you enter the door, you are often wearing a white vest and shorts, and the knee bones are clearly protruding.

The common denominator is gout, bloodletting, neat clothing, and a bad reputation.

"Now there may be another victim, and the investigation will start immediately. Wang An ordered to everyone present.

Jiang Chen walked down with the evidence and saw Fan Xiaorou playing with the corpse.

"Sister Xiaorou, is there anything wrong with the wound of the first victim?"

Fan Xiaoju said: "It is a knife inserted into it, slowly advancing, and the degree of the wound is from shallow to deep, straight to the intestines." "

Jiang Chen squatted down and asked, "What about this now?"

"It's a folding knife, about 7 centimeters long, and the specific injury needs to be moved back and dissected. "

Fan Xiaorou changed into a latex glove and continued to play with the corpse.

Jiang Chen saw that she was only wearing one glove.

Curious, he asked, "Is the forensic doctor not wearing two gloves?"

Fan Xiaorou raised her voice and said, "The two gloves will rub, and then they will be easy to break." "

"This is similar to some people who think that two small umbrella covers can be more effective, but in fact, the friction between the two layers can easily make it break. "

She gave the eyes of an old driver.

Jiang Chen was dumbfounded, this description is really okay.

Returning to the suspect, wearing two gloves is for safety.

But can fingerprints be detected with such a little bit of plastic?

The criminal police brigade in the middle of the night, brightly lit.

Jiang Chen sat in the conference room and looked at the clues on the whiteboard.

Wang An said: "The first suspect is uncertain, the second needle is very professional, it is suspected that it is a doctor or nurse, and the third victim has a bad reputation." "

To sum up, the murderer killed with a purpose, and the two victims had the same modus operandi. "

"Focus on the investigation from the victim's social circle, but anyone who has a conflict with the deceased should ask clearly, and no one can be let go. "

The investigators present were in good spirits.

Jiang Chen suddenly raised his hand and said, "There is not necessarily a conflict. "

"The murderer is a calm and indifferent person, and basically this kind of personality cannot clash with the victim. "

Wang An asked, "What is that?"

Jiang Chen pondered for a while and looked at the document.

"From the perspective of personality, this murderer has a sense of justice. "

He analyzed it from the position of a murderer.

Wang An frowned and said, "You analyze it." "

As soon as Jiang Chen stood up, there was a knock on the door outside.

"Come in. Wang An shouted.

Xiao Zhe hurriedly said: "The broken plastic has fingerprints. "

This sentence brought a glimmer of hope to everyone.
