At one o'clock in the morning, the starry night was lonely, and the whole city had fallen into a deep sleep, but the interrogation room of the police station was brightly lit.

The suspect Huang Weisheng was sitting in the interrogation room, his lips pursed, his expression was calm, and the expression on his face did not have a trace of waves, let alone the fear and guilt of being arrested.

Xu Chengyan and Xiao Tiao of the Serious Crime Unit were sitting across from him, looking through the autopsy report and the information collected by the forensic department at his home and workplace.

After resting for a while in the pantry of the police station, Qiu Lan, who escaped from danger, went to the forensic department to get the tools for collecting live evidence and rushed to the interrogation room.

"Pei Pei, how is the situation now?" Qiu Lan strode to Pei Pei outside the interrogation room, her eyebrows moved slightly, and she asked in a low voice.

"Doctor Qiu, are you here?" Pei Pei pursed his lips, looked at the small window of the interrogation room with a serious face, and shook his head slightly, "It's been half an hour, and the head hasn't asked anything, this person hasn't spoken, and he is silent when he asks anything." ”

Qiu Lan was not surprised by her answer.

When she was in the private room of the bar, she could already see his tough heart in the eyes of the suspect. Moreover, if he didn't have such psychological quality, it would be impossible for him to kill people and abandon corpses so calmly, let alone calmly remove all traces of the scene.

"Okay, I see, I'll go in first to do a live forensic on him. Qiu Lan's eyes sank, and the expression on her face became a little colder, "He doesn't speak, it doesn't mean his body and he doesn't express it." ”

As she spoke, she knocked on the door and pushed it in.

Huang Weisheng in the room was just like Pei Pei said, his eyes were closed indifferently, his lips were pursed into a straight line, his five fingers were slightly bent into a relaxed state, and the muscles of his face were relaxed, without a trace of tightness.

He was indifferent, as if nothing had happened before, or rather, it had nothing to do with him.

"Huang Weisheng! I'll say it again, you'd better tell me everything you know honestly, don't think that if you don't say it, I won't know anything!" Xu Chengyan frowned, stared at the person in front of him angrily, and slammed his fists on the table a few times.

However, Huang Weisheng, who was sitting opposite him, had no waves in his heart when facing all this, as if he was in a realm outside the sky, and his ears did not hear what was going on outside the window.

It's useless like this, no matter how Xu Chengyan threatens, he won't say it.

"Officer Xu, let's talk about the interrogation, I'll do live evidence for him first. Qiu Lan put the box in her hand on the table and spoke slowly, her tone calm.

She indifferently fiddled with the utensils in the box, and put everything in front of the suspect Huang Weisheng one by one.

"Mr. Huang, it's okay if you don't speak, but I'm going to do a living forensic for you now, and I hope you will cooperate. Qiu Lan glanced at him indifferently, her gaze cold.

Suddenly, after hearing this voice, the man raised his eyes, glanced at the person in front of him with deep meaning, his eyebrows moved slightly, and a touch of fierceness slipped under his eyes, "It's you?"

The sound was so small that it was almost inaudible, but Qiu Lan still took it in her ears.

"I am Qiu Lan, the forensic doctor in charge of this case, not an addict, nor a rich second generation. She paused, looked him up and down, and said coldly, "Please take off your shirt and shorts, and now I'm going to do a live testimony for you." ”

The suspect gritted his back molars, the corners of his mouth were slightly raised, his eyes were closed indifferently, and he did not move, and he had no intention of cooperating at all.

Qiu Lan had expected this trick a long time ago, she pursed her red lips, picked up the scissors on the table and walked in front of the man, and without saying a word, she cut open his clothes.

"What are you doing, why are you cutting my clothes!" Huang Weisheng instantly became furious, impulsively waving his handcuffed hands, his face full of violence.

"Officer Xu asks you something, you can not answer, it is your right to be silent, but I want to do live evidence for you, and it is also your obligation to cooperate, if you do not refuse to cooperate, it is also my right to take measures. Qiu Lan moved her lips coldly, and the movements in her hands were still carried out neatly.

In three or two clicks, the suspect Huang Weisheng only had a pair of shorts left on his body to cover his shame.

"Next, you can also say nothing, because your body will answer for you. Qiu Lan put the broken fabric on the table, picked up the cotton swab and flashlight, and slowly looked back at the two police officers behind her, "Excuse me, help me pull his mouth away." ”

The two police officers standing in the back hesitated for a moment after hearing her words, but after seeing Xu Chengyan nodding, they walked to the suspect's side without hesitation and opened his mouth according to Qiu Lan's instructions.

Qiu Lan, who was expressionless, took out some oral sample tissue from his mouth and put it into the sample bottle, and said to himself as if unintentionally, "There are so many ulcers in the mouth, it seems that you are not very angry, you should be angry with those rich second-generation addicts." ”

When he heard this, Huang Weisheng's expression still did not change at all, but a strange light obviously flashed in his eyes.

There was no doubt that Qiu Lan's words touched the darkest place in his heart.

"By the way, when I looked through the past case materials before, I found that the deceased in one case was named Huang Weiming, your name is so similar, are you brothers?" Qiu Lan picked up the flashlight, checking the wounds on the suspect's body little by little, but muttered something else in her mouth.

"601, Block B, Shingfu Gardens. Qiu Lan paused her voice, pursed her red lips, and pretended to be puzzled, "I remember, the household registration place on your ID card is the same as his, you are really brothers, what is the cause of death in that case?"

"Drugs, it seems to be related to drugs. She frowned, stopped what she was doing, and stared meaningfully at the person in front of her, "This can't be your motive for killing, right?"

After the words settled, Qiu Lan picked up the scale next to her and measured Huang Weisheng's fingertip distance in detail, "Xiao Cong, make a record, the distance between the tips of your right fingers is twenty-three centimeters, and your left hand is twenty-two centimeters, go back and compare it with the traces on the deceased's body." ”

The cold voice suddenly echoed in the low-pressure interrogation room, and Zhigao, who was sitting on the side, frowned, and looked at the person in front of him blankly, and couldn't help but have some doubts in his heart.

These words, they have already said to the suspect, but it has no effect, so what's the point of her mentioning it again?

Although Zhigao didn't know in his heart, Xu Chengyan's eyes were full of trust.

He knew that Qiu Lan had a reason for everything she did, and he only needed to believe in her unconditionally, not only because he admired her, but also because the previous case had made him look at her with admiration for a long time.

She's not your average forensic doctor.

At this moment, Qiu Lan stopped what she was doing, and her eyes were fixed on several blood marks on the suspect's hands, "Xiao Cong, take pictures, there are four blood marks on the suspect's left upper arm, according to the degree of healing, it should have been scratched four or five days ago, which is consistent with the time of death of the third deceased." ”
