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

"On the deceased's left arm, there is a needle, the needle is very new, it should have been made in the past two days. "

Fan Xiaorou opened the file and pointed to the photo, with bruises on her arms.

She continued: "But the amount of blood on the victim's body is still 525ml. "

Jiang Chen hummed and said, "Check Ding Wei's physical condition, there is a problem with one of his organs, and his urine is alkaline, which means that it is abnormal." "

"Xiao Luo, you check the people around him and the neighbors for me. "

"Xiao Zhe, you come back with me to the scene of the crime, I need to confirm something. "

"Xiaorou, you are helping me check Ding Wei's wound and needle mouth, and put it on my desk tonight. "

Jiang Chen said to them.

The three of them said yes in unison.

Huh? Something's wrong, what's the matter with blurting out?

Wang An narrowed his eyes and looked at him incredulously.

Fan Xiaorou patted Jiang Chen's head: "You kid, I think you're the top." "

Jiang Chen said helplessly: "Sooner or later, I will sit in this position." "

He looked at Wang An meaningfully.

Master Fan Xiaorou left without remembering the villain.

The others also listened to Jiang Chen's orders and worked.

It seems that Wang An's sense of existence is low.

He sneered

, "This Officer Jiang, have you forgotten me?"

Jiang Chen raised his head blankly and smiled: "You sit back and wait to receive the merit." "

Of course, Wang An is 100% convinced of him.

The odds of solving the case are 100%.

According to the cases he solved in the past, there are first-class and third-class merits.

It's just that he gave it all to the collective, that is, everyone got the credit.

"Chen, how do you feel about becoming a full-fledged police officer tomorrow?" asked Wang An.

Jiang Chen gave him a smile.

If it weren't for the fact that there was a memorable one of the detective skills, I'm afraid it would be really sad.

When you become a police officer, you can't be a delivery person.

It's a pity that I can't find my grandfather.

"If you think about it, that is, to crack this case first, and catch the murderer, one less criminal, Jiangzhou City will be stable. "

After Jiang Chen finished sighing, he picked up the cigarette on the table and put it in his mouth.

Xiao Zhe, as a trace inspector, took his equipment and tools and came to Jiang Chen.

"Go, everything is ready, let's go. "

Jiang Chen responded: "Okay." "

Wang An followed the two to the scene of the crime.

Five hours have passed since the homicide.

The

cordon was raised, and the smell of rust dissipated.

People in the hallway discussed.

"Damn it, this kind of person lends money maliciously. "

"Evil is rewarded for evil, God has eyes, and the bad guy is finally dead. "

"It is said that people were forced to jump off the building. "

Jiang Chen recorded these words.

It seems that the victim's reputation is very bad, and I wish he was dead.

As soon as he walked into the second floor, Jiang Chen ran into Tong Dahai, holding a pile of garbage and passing by several people with expressionless faces.

"Wait. Jiang Chen turned his head and called out to him.

Tong Dahai looked back at him, as if staring at his prey.

"Is there something wrong? officer. "

Wang An glanced at him, then at Jiang Chen, his eyebrows flashing in surprise.

He saw that Jiang Chen's eyes had become deep, and he had a feeling of great insight.

It's like looking at Tong Dahai.

Jiang Chen asked, "You take out the garbage, be careful." "

Tong Dahai frowned slightly, and he was concentrating for a few seconds, and he shouldn't have turned his head and left.

Wang An watched the people leave and asked Jiang Chen, "Do you suspect that he is the murderer?"

Jiang Chen shook his head: "I'm not sure, but he has a psychological disorder, and he can only be judged by calling on the testimony of his neighbors." "

"As long as there is a suspicion, go to arrest and interrogate. Wang An said.

Jiang Chen lowered his eyes, even if he was arrested and interrogated, there was no monitoring here, and the search was more difficult.

It can only be found from the victim's personal circle.

"Lao Wang...... How's your mental profile?".

Psychological profiling, that is, the result of speculation based on the characteristics and personality of the suspect, as well as the case itself.

If the guess is wrong, the overall direction of the investigation is wrong.

The effort and time spent are not conducive to solving the case.

Wang An said: "I speculate that the other party is a person who can give injections. "

Jiang Chen raised his head: "Okay, I'll keep you this key point first." "

Coincidentally, Tong Dahai came back with something, Jiang Chen glanced at it, and his pupils couldn't help but dilate.

It is a disposable syringe.

Coincidentally, the eyes of the two collided again.

An opponent Jiang Chen has ever encountered.

Look at him directly, like a man looking at him.

Tong Dahai passed Jiang Chen, showing disdain for them.

"Tong Dahai, I have something to ask you. Jiang Chen stopped him and said.

"Officer, what's wrong? I didn't kill anyone. Tong Dahai said expressionlessly.

"What are you buying this syringe for?" Jiang Chen asked.

Tong Dahai stared at him in the eyes and said, "Use it to draw some blood." "

Jiang Chen felt that he was too calm.

Whatever he says is expressionless.

The calmer the person, the better the psychological quality.

But are there really no flaws?

Wang An heard movement outside, saw Tong Dahai, showed his police ID, and said, "There are some things, I want to ask you to go back to the police station to investigate." "

Tong Dahai looked at Wang An and said calmly: "Okay." "

The more Jiang Chen looked at him, the more strange it became.

It's like it's targeting a certain profession.

Especially like a policeman, with disdain in his eyes.

"Jiang Chen, you investigate here first. Wang An said.

Just as Tonghai wanted to go to the house, Wang An took his hand and asked seriously: "Don't put down your things, go back to the police station together, I have a lot to ask you." "

Tong Dahai's eyes showed hatred at this time.

"Stop staring, go back to the bureau and have a cup of tea. Wang An said.

Jiang Chen watched him being taken away, and looked at Jiang Chen from time to time, and that look was saying that you wronged me.

Why was he arrested? It is estimated that Wang An's psychological speculation and seeing Tong Dahai's disposable needle.

Xiao Zhe behind him said: "Brother Chen, there is a discovery." "
