The forensic wife is very nice to me

The iron wire on the wall can suffocate a person, but it is absolutely impossible to strangle the neck of a human body to the extent of the dead. Punching and kicking can cause bruises all over the body, but it is impossible to cause marks on the chest.

In this case, there is one more important point.

The suspect Xiong Wei is just a person who has not graduated from junior high school. How could he know how to use a chemical substance that is not commonly seen in bill hydroxyacid.

Just the right concentration, knowing how to use the corrosiveness of this chemical substance to disturb the police's sight, this matter is definitely not something he can get out of, so who would it be?
Suddenly, Qiu Lan thought of someone.

He has been with the scar-faced man all the time, and when they were in the old factory building, the conversation between the two of them also confirmed that the man knew about the deceased.

"Officer Xu, have you checked out that man who is a little more handsome?" Qiu Lan raised her eyes and stared at the person in front of her solemnly, with a calm tone.

"Found it, Xiong Wei has just been interrogated, and he will be interrogated soon." Xu Chengyan nodded, pursing his lips lightly, "That person's name is Shen Chenhua, who has been with Xiong Wei for almost three years, and they are all drug dealers. "

With a serious face, Qiu Lan lowered her eyes, silently thinking about the whole thing.

Followed for three years?

After such a long time, the relationship between the two should be pretty good, and Xiong Wei should still trust him.

"Doctor Qiu, what are you thinking?" Seeing her pensive look, Xu Chengyan couldn't help moving his lips and asked softly.

"I was just thinking that the doubts in this case have not been resolved." Qiu Lan frowned, and glanced at Xu Chengyan thoughtfully, her eyes flickering.

She told him all the doubts in her heart. After listening, Xu Chengyan nodded in agreement, with a slightly cold expression on his face.

During the interrogation, that Xiong Wei was obviously a typical hooligan, superficial, irritable, impulsive and stupid, and that case, from the very beginning, they felt the pressure and concluded that the murderer was a well-thought-out high-IQ criminal By.

Xiong Wei, who was sitting in the interrogation room at this moment, really didn't seem like a well-planned person. Besides, during the entire interrogation process, he never mentioned the matter of chemical substances, nor did he mention the scar on his chest.

Could it be that he still has reservations?

But the two crimes of murder and drug trafficking are enough to sentence him to death. What else can he not say?

No, he might be covering someone up, or in other words, there is something hidden behind it, something he doesn't even know about.

The serious crime team checked Xiong Wei's information in the archives department. He has no father, no mother, no children, and no wife. He only occasionally goes to a certain street to do illegal activities, but he has no fixed concubine.

Then it can only be the second possibility, that is, there are other things that he doesn't know, and apart from a few younger brothers who have been with him for so many years, the only one who lives with him in the factory is inseparable Shen Chen Hua.

"Officer Xu, do you have that person's information? I want to see it." Qiu Lan lowered her eyes, pursed her red lips lightly, and her eyes were full of deep meaning.

In the monitoring room of the interrogation room, Qiu Lan got the information from the serious crime team, and Peipei and the others also brought another key person to the interrogation room.

Compared with Xiong Wei, Shen Chenhua is much calmer.

He pursed his thick lips lightly, his brows stretched, his eyes were calm, and the expression on his face was calm, as if nothing that happened before had anything to do with him.

"Shen Chenhua, do you know the reason why we brought you here today?" Xu Chengyan sat on the chair without changing his expression, leaning back, deliberately making a relaxed posture.

"I know, I, I helped Brother Wei today and did something bad, but this is not what I want." Shen Chenhua lowered his eyes, his eyes fluttered, "Actually, I was forced, if I don't If you help Wei Ge, he will beat me."

"Just, like that day."

"That day?" Xu Chengyan raised his brows, keeping his sharp eyes on him, "Are you talking about the day Xiong Wei beat Tan Yinsheng to death?"

After hearing his question, Shen Chenhua frowned, hesitated for a moment, then nodded resentfully, "Yes, it was that day."

The answering voice trembled, he seemed to be afraid of the scar-faced man.

Looking at his expression, Qiu Lan frowned, and a trace of doubt slipped through her deep black eyes.

When the factory was broken down, Shen Chenhua was not afraid of Xiong Wei, but the man with the scar on his face was always asking for his advice, and the relationship between the two was somewhat like brothers.

So here, how could he have such an expression, admitting that matter as soon as he came?

A huge question lingered in Qiu Lan's mind, but after she read Shen Chenhua's information, some things became clear quietly.

"Shen Chenhua, were you by the side when Xiong Wei killed the victim? A bystander? Or an accomplice?" Xu Chengyan stared coldly at the person in front of him, his tone cold.

But the white-faced boy didn't seem to be frightened by his attitude, the expression on his face was as calm as water, and he even said that this calmness was a bit unusual.

"No, officer, I wasn't there at the time. I saw it later. Brother Wei threatened me not to let me speak out. I dare not." Shen Chenhua twisted her thick eyebrows on her forehead, her eyes drooped, Helpless and cowardly.

"Officer, you believe me, Tan Yinsheng's death has nothing to do with me, I am innocent."

"Innocent? I don't think you are very innocent, right?" Xu Chengyan picked up the document in his hand and put it in front of him, "You have been under Xiong Wei's command for three years and have been involved in drug trafficking. You say you are innocent? "

Looking at the information on the table, Shen Chenhua opened his mouth in shock, "What, what is this? I don't know."

He pursed his lips, his eyes were blurred, and he looked dazed and ignorant, "Officer, this, I don't know about this, I don't know that Wei Ge is still doing these businesses, I really don't know."

"When I came here, I had no place to live and no job. Wei Ge took me in and found me a job. I'm still working as a chef at the Sunshine Restaurant. I really don't know. "

If Qiu Lan hadn't witnessed his words and deeds in front of Xiong Wei with her own eyes, she might have been deceived by his innocent performance in the interrogation room.

At this moment, the door of the monitoring room was gently pushed open, and Cao Fan from the forensics department came in with the materials they had identified overnight, and told them the results.

The truth is finally emerging.

However, the evidence is not enough to convict, and I am afraid that it will take a lot of thought to get the real murderer to plead guilty.

Qiu Lan took a deep breath, walked out of the monitoring room, stood in front of the interrogation room door and knocked lightly on the door.

"Come in."

She opened the door calmly, with a smile on her lips.

This smile is meaningful.

"Officer Xu, I have a few questions and I want to ask Shen Chenhua, can you give me a few minutes?"

"Yes." Xu Chengyan nodded, walked to the side silently, and gave her the seat.

Qiu Lan with a calm face put the materials in her hands on the table in the interrogation room, then walked to Shen Chenhua's side, and said calmly, "The winner of the special prize in the National Chemistry Competition, a graduate student in the Chemistry Department of Hengcheng University."

"I have to say that you have really accomplished a lot in the field of chemistry."
