The forensic wife is very nice to me

"The deceased was 170 centimeters tall and had no bruises under the skin. There were no other wounds on the back or abdomen, but there was a wound on the head, which should be a concussion. According to the degree of healing of the wound, it was about three days ago."

Qiu Lan checked the suspect's body step by step according to the procedure, but when the arm was checked, Zhou Peng suddenly kept covering his right arm and refused to let go.

"Officer, I've already said that I really didn't see Shu Qiming that night, why are you still checking up and down like this, it's a waste of police force." The suspect frowned tightly, and there was a hint of guilt in his hasty voice. .

"Mr. Zhou, did you see the deceased that night, or what did you do? We will find out. I hope you will cooperate with me now. I want to check your arm."

The more hidden the place, the more suspicious it is, Qiu Lan knows this well.

Seeing her tough attitude, the frowning suspect involuntarily lowered his eyes and dodged around.

"Mr. Zhou, please cooperate, otherwise, we will take coercive measures." Qiu Lan's eyes darkened, and she spoke indifferently, with a cold voice, "Also, the crime of intentional homicide is serious. If you really want to prove your Clear, let me check."

After hearing her words, the panic-stricken suspect sighed heavily, frowned and struggled for a moment, and finally stretched his arms in front of her.

"There are three new needle holes on the right arm, which should have been left not long ago, and there are some old needle holes." Qiu Lan frowned, carefully inspecting every inch of Zhou Peng's skin, and the expression on her face became more and more serious. more and more dignified.

With a sallow complexion, a thin body, and various needle holes on her arms, Qiu Lan finally came to a conclusion after combining all the test results.

She took out the needle tube, collected blood samples from the suspect's body, and then added two transparent and colorless chemicals.

Gently oscillating, the blood changed from red to black purple.

This phenomenon just confirmed Qiu Lan's conclusion.

"Officer Xu, this Mr. Zhou should be an addict. He has the habit of injecting drugs for a long time, and this habit should last for two years."

After the words were settled, a heavy sigh followed, and the panic-stricken suspect frowned, lowered his head, and was depressed.

"Yes, for two years, I have been refusing to say what I was doing that night because of this." He shook his head weakly, his voice trembling slightly.

"That night, I was going to pay back the money to Shu Qiming, but I didn't expect that when I was about to go out, I became a drug addict. It doesn't matter."

"Alone at home?" Xu Chengyan emphasized his tone, put his hands on the table, stared at the person in front of him with cold eyebrows, and asked sharply; "You are at home alone, so you don't have an alibi?"

"Yes." The suspect nodded tremblingly, frowning slightly uneasy, "But I really didn't leave the house that night, and I didn't see Shu Qiming, even he died because you found me today I just found out."

"Really, you believe me, really!" Zhou Peng leaned forward excitedly, staring firmly at the person in front of him, eager to clarify his suspicions.

After all, murder is the death penalty, but taking drugs will only send you to a drug rehabilitation center for forced drug rehabilitation. As long as you are a person with a brain, you will understand which is more important.

After hearing his words, Qiu Lan and Xu Chengyan, who were standing aside, looked at each other with meaningful eyes.

"But only you know if you go out or not, we don't know, what if you killed someone, or became addicted to drugs when you killed someone?" Xu Chengyan frowned, staring at the person in front of him seriously , Asked back.

"No, it's impossible. I really didn't, I didn't." The suspect shook his head hastily and strongly denied what he said.

Maybe it was because his head was shaking too much, which involved the wound on the back of his head. Zhou Peng subconsciously touched the location of the wound.

"How did you get the injury on the back of your head?" Qiu Lan glanced at him sharply, and said indifferently.

"Injury?" The suspect was stunned for a few seconds, his eyes flashed suddenly, "I remembered, this injury was that night, I injected drugs, maybe I was too excited, so I knocked down somewhere, and I was injured the next day. When I woke up, it was already like this."

Listening to his words, Qiu Lan suddenly thought of something, she lowered her eyes thoughtfully, and thought for a moment in silence.

"Officer Xu, I need to take him to the forensic department for a CT scan of his head. Also, I'm afraid I need to ask expert Cao to go to his home to confirm whether he was injured at home."

"Okay!" Xu Chengyan nodded firmly.

Twenty minutes later, in the laboratory of the forensic department, Qiu Lan was carefully observing the suspect's CT film, while Xiao Cong was on the sidelines conducting a chromatographic examination on the suspect's blood sample.

The wall clock on the wall was ticking, and the two people in the laboratory were staring at the things in their hands, not daring to lose their minds.

In the field of science, carelessness is the most taboo. After all, a difference of a few tenths of a millimeter may cause irreparable damage.

After another half an hour, Qiu Lan finally saw what she most wanted to see.

At the same time, she just received a call from Cao Fan, an expert in the forensics department, and learned about the situation at the suspect's home.

Everything is confirmed.

She connected the serious crime team and told them the final result, "Zhou Peng has never been to the scene of the crime, or in other words, he has no way to go to the scene."

This result made the members of the serious crime team feel a little surprised, and it was not until Qiu Lan stated all the reasoning once that they dispelled their doubts.

On the night of the incident, the suspect Zhou Peng did send a message to find the deceased, but before he had time to go out, he became addicted to drugs.

After injecting drugs, the back of his head hit the wooden chair handle due to excessive excitement, which happened to injure the lower body of his brain, causing him to faint directly.

After fainting, the human body will secrete an acid group, which will form different forms according to the change of time, and there are specific parameters in the scientific forum.

And Qiu Lan happened to find one of them in the chromatographic fluid separated by Xiao Cong, and according to the calculation of time, it was an hour before the death of the deceased.

That is to say, the suspect Zhou Peng had fainted an hour before the death of the deceased. If he had to wait for him to wake up, it would take at least eight hours, so he had no chance to kill the victim.

After the case got into trouble again.

All the people had to go back to the starting point of the whole case and rethink the original question.

If the man wearing the mask mentioned by the female wounded was not Zhou Peng, who would it be?

Could it be that this case was not a murder, but an emergency?
But there was no trace of a third party at the scene of the crime. If it was due to some unexpected situation, how could the murderer clean it up so cleanly?
