"Hello Miss Huang, there is no progress in the case for the time being, and we are here today to ask some questions related to the scene of the crime. Xu Chengyan walked up to her and nodded in response.

Xiao Tiao, who followed him, took out a notebook and prepared to start recording his confession, while Qiu Lan stood silently beside him, quietly observing the words and deeds of the female wounded.

"Officer Xu, just ask if there is anything, and I will definitely cooperate with you. The female injured Huang Lishan hung her head with a sad face, and sighed weakly, "Qiming's death is unknown, and I also want to find the murderer behind it." ”

"Okay, in that case, let's get started. Xu Chengyan frowned, and the expression on his face was slightly serious.

According to the process of questioning, he carefully re-questioned all the circumstances at the scene of the crime.

The same male deceased received a text message in the middle of the meal and left, and the female injured saw that the male deceased had not returned, so she went out.

By the time the dead man was hit, he had fallen in a dimly lit alley, surrounded by a pool of blood, followed by a man wearing a hat and a mask who rushed out of nowhere and gave her a knife.

She fainted in pain, and when she woke up, she only glanced at Qiu Lan and lost her strength.

She didn't see what the man looked like from beginning to end, and she didn't know where he had left.

The process of questioning was very smooth, and although the female injured person was very sad, she always answered Xu Chengyan's questions very cooperatively, and her answers were exactly the same as before.

However, this is the same answer, and there is a fluent rhetoric, which attracted Qiu Lan's attention.

Half an hour later, in the corridor outside the ward, Xu Chengyan, Xiao Tiao, and Qiu Lan stood at the corner window.

"Doctor Qiu, how is it? Did you notice anything unusual?"

"Hmm. Qiu Lan pursed her red lips and nodded firmly, "Officer Xu, when we observe a person, we usually pay extra attention to the micro-expressions of the human body, as well as the muscle groups on the face and body. Among them, the part of our forehead is called the reliable muscle, and the part of the corner of the brow is called the difficult muscle. ”

"Reliable muscles are difficult for someone to deliberately control, and it usually appears inadvertently when people are sad and uncomfortable, but I found that female injured people do not have such muscle twitches, but are the difficult muscle parts."

In order to allow Xu Chengyan and Xiao Tiao to better understand the information of this part, she deliberately pointed out the part she emphasized.

"When you inquired just now, I noticed that the corners of her eyebrows kept pressing, which is a sign of difficult muscle twitching, indicating that the female injured person is in a difficult situation, most likely making up lies, and still trying to say what to say before you can believe it. ”

The voice settled, Qiu Lan paused, her brows moved slightly, and the topic shifted to another doubtful point.

"Also, when it comes to trying a case, there is another important point. Just now, when you asked about the female injured person, she always looked very sad, so she kept her head down and didn't look at you. ”

She furrowed her brows, and the expression on her face became a little heavier, "There is a proper term in the relevant course of interrogation, called fixation time, and under normal circumstances, it is divided by fixation time accounting for one-third to two-thirds of the interrogation time. ”

"If it is higher than this percentage, it means that the suspect is very interested in the current topic and has a small chance of lying, but if it is lower, it means that she is in a state of fear and hostility, and it is very likely that she is lying. ”

"And if you had paid attention just now, you should have noticed that the female victim had only glanced at you a few times at most. ”

After listening to her words, Xu Chengyan and Xiao Tiao both nodded in agreement.

"Dr. Qiu, you're right, she really didn't look at me just now, and her eyes were a little weird, always staring at the one on the far left. Xu Chengyan lowered his eyes thoughtfully, and the more he thought about it, the more strange he felt, "It seems that the female injured person is indeed hiding something from us." ”

"Yes, boss, didn't you ask her about her relationship with the deceased just now? She only said that the relationship was very good, and she didn't say a word about the deceased Shu Qiming having an affair. Xiao Tiao furrowed his brows and tapped his chin lightly with his hand, pretending to be deep, "The more you hide it, the more problematic it is." ”

The last sentence was a common phrase on Qiu Lan's lips when analyzing the case, but she didn't expect to be preempted by Xiao Tiao, she chuckled lightly twice, and jokingly said: "Xiao Tiao is good, this time it's faster than I said." ”

"What. Xiao Tiao scratched his head in embarrassment, and the corners of his mouth raised slightly, "This is what I usually learned from watching Dr. Qiu and the head solve the case, or Dr. Qiu is amazing, standing next to it and looking at it a few times, I found out that she was lying." ”

"Yes, boy, I'll have to learn from Dr. Qiu in the future. Xu Chengyan patted him on the shoulder with deep meaning, with a smile on the corner of his mouth, but his eyes were full of admiration and admiration for Qiu Lan.

In his eyes, Qiu Lan is a goddess with both appearance and wisdom.

After a few brief analyses, they left the hospital, ready to go to the police station to look at the evidence they had gathered again.

The first two days their direction and attention were on the mysterious third party, but this time it was back to the female wounded.

If you look at the evidence again, you may find something new.

The police car was driving straight on the main road of City A, a cool breeze was whistling outside the window, and Qiu Lan, who was sitting in the car, silently checked the information in her hand.

She knows the content of the information by heart, but every time she looks at it, she will have a different opinion, so she will still scan it again and again with keen insight.

Suddenly, her gaze was fixed on one of the images.

This is a chat log, a message sent by a woman with a note of Xinlin to the deceased, and the message is very simple, just a few words.

"Yes? I miss you. ”

However, the timing of these words is a big question.

Qiu Lan, who had a serious face, flipped to the previous information, and compared them one by one, the time of this news was very close to the time when the male deceased was killed.

According to the restaurant's surveillance records at the time, the message should have been sent three minutes after the male deceased left the restaurant.

Suddenly, Qiu Lan thought of Li Shanghan's two words again, "love killing".

She suddenly guessed the motive of the female wounded man.

It's not murder, it's a murder in a fit of rage.

"Officer Xu, do you still have the surveillance video of the restaurant at that time?" Qiu Lan put down the things in her hand and asked eagerly.

"Yes, what's wrong?" Xu Chengyan glanced at her slightly, a little unclear.

"Let's go see it again, I want to see if the male deceased left with his phone when he left the restaurant?" Qiu Lan furrowed her brows, her eyes deep.

If the male deceased had left with his mobile phone, the female victim would not have been able to see the message, and her reasoning would not have been valid, but if the male deceased had not brought it, the female victim would have seen the woman's message.

There's nothing a woman can't do when she's angry, so it's likely to be a homicide that is emotionally provoked.
