Bai Rushuang opened her mouth, unable to say a word, but she felt like a ball of cotton was blocked in her chest, and she was so depressed.

She remained silent and lowered her eyelids.

She thought that she could now understand why Lu Jingming fell in love with Wei Qingsong, not only because of her heart-wrenching beauty, but also because of her calmness and wisdom.

Despite her pride, she must admit that she is not as good as Wei Qingsong, from all levels.

The car had already left the city. It was getting late, and the trees on both sides of the road were lush and covered with leaves, swaying in the darkness.

Wei Qingsong withdrew his gaze, silent for a moment, and said lightly: "I have four discoveries about this case at present."

"First, the murderer is a local, about 30 years old, single, very familiar with road traffic, and has his own transportation tools. I preliminarily speculate that his profession is most likely to be a driver, courier, takeaway, and so on, and someone who knows the road environment of Quyang County well."

"Secondly, the murderer's relationship with women is very complicated, with both hatred and sexual desire. In the past two years, he should have suffered very serious emotional trauma. When we find him, a large number of pornographic magazines will definitely be found in his home."

"Third, when the four deceased were killed, they all wore black hip-covered skirts. This is a symbol and a symbol for the murderer. He has an alternative fascination for women wearing black hip-covered skirts. In the murderer's emotional life, there must be such a woman who likes to wear black hip-covered skirts, which has a very special significance to him."

"Fourth, on August 22, the day when the third deceased, Jiang Keying, died, the murderer experienced a great setback. I personally prefer that his frustration comes from his work."

Bai Rushuang couldn't help but be stunned. After a long time of reaction, she asked in confusion: "I can understand the first three points, but how do I get the profile of the fourth point?"

The four deceased were found in sparsely populated suburban highways, and they were far apart, and were more than ten kilometers away from the central urban area of ​​Quyang County. Therefore, the murderer had transportation and knew Quyang County very well, so he had a reasonable understanding of these.

But why did he say that he suffered setbacks on August 22? Bai Rushuang couldn't figure it out.

"The biggest feature of serial killers is that they are 'fixed', fixed targets of killing. All of our four dead are wearing black hip skirts, and they are all single unmarried women around 30 years old."

"A fixed killing time, all four dead people were injured in the range of 9 to 11 p.m.."

"There are also fixed ways to kill people. Except for Jiang Keying, the other three dead were all injured and suffocated. The four dead were all violated after death."

"The only one who died of the deceased Jiang Keying was hit by a blunt weapon in her head." Wei Qingsong picked out Jiang Keying's autopsy report and held it in his hand. "And, it was hit by multiple blows to death. What does this mean? It represents anger."

"Then, could it be that Jiang Keying said something that angered the murderer, which would cause the murderer to abuse her?" Bai Rushuang rigorously raised another possibility.

Lu Jingming bent his finger and tapped the back of the lower chair: "Follow six pages of information on the computer to read from the third line."

Bai Rushuang was stunned for a moment and subconsciously did as she did.

Turn the information six pages forward, and the mouse cursor stays on a row of black characters.

"...According to the visit, the deceased Jiang Keying, 30 years old, is a music teacher. He is gentle and kind. He rarely has disputes with others and has a good relationship with his neighbors and colleagues." Bai Rushuang said lightly, suddenly realized something, and his words stopped abruptly.

How could a person who is recognized as having a good temper tantrums to stimulate the murderer?

Wei Qingsong raised his eyebrows at Lu Jingming and continued, "So, on this day, the murderer must have encountered something very unpleasant. He was full of anger and desperately wanted to vent his resentment. So, only when he killed the deceased Jiang Keying, his way of killing changed because he was venting his anger."

"Immediately afterwards, he committed the fourth crime on August 27, which was quite intensive, which shows that the source of his anger and had a great impact on him. So, I think his anger comes from his job, which is very likely to be unemployment, deduct wages, demotion, or being scolded by his boss and clients."

Bai Rushuang suddenly realized: "So that's the case, Miss Wei, you are so awesome."

But soon, she sighed with a bitter face again: "But, as you said, this range is too large. She is about 30 years old, single, and has a job as a driver, courier or takeawayman, and is lustful... Looking at the entire Quyang County, similar people are like crucian carp, how should I find them?"

Wei Qingsong thought for a moment, took out another piece of paper from the pile of information in his hand, and looked through it carefully: "When you investigated the first deceased Yu Fangfang, have you any special discoveries?"

Bai Rushuang frowned and thought hard.

Lu Jingming knocked on the back of the chair again, his voice low and powerful: "Follow the twelve pages further, the seventh line."

Before Bai Rushuang could make any moves, Lu Jingming said in a deep voice: "During the first round of investigation, there was a courier named Zhang Ming. On February 6, he and Yu Fangfang had an argument over the express delivery problem. According to his confession, he slept at home that night and no one testified. Therefore, he did not have a clear absent proof. Why did the Quyang police continue to investigate him?"

Bai Rushuang rushed to the page Lu Jingming said. From the seventh line, it was the details of the police's investigation into Zhang Ming.

She was speechless. For some reason, she actually felt that Lu Jingming and Wei Qingsong should be a natural couple.

One is always remembered by the case files, has extremely keen judgment skills, and is very skilled, while the other is good at inferring the murderer's psychological state from the details and making accurate profiles.

What a wonderful and perfect combination?

Bai Rushuang came back to her senses for a long time and said slowly: "We did investigate Zhang Ming at that time. Although he did not prove that he was absent, he did not have the conditions to throw the body, because he only had a three-wheeled vehicle for express delivery, and the body of the car had a very conspicuous sign."

"The security guard in the community where Zhang Ming lives can testify that the express car had been parked at the entrance of the community that night and had never left."

Wei Qingsong pondered for a moment and asked, "What about his immediate family? Is there a car?"

"Uh..." Bai Rushuang hesitated for a moment and said hesitantly, "Zhang Ming's father has a car, but his father insisted that he did not lend the car to Zhang Ming that day."

When Lu Jingming heard this, his eyes were slightly darker and he said coldly: "What about the evidence? Just relying on the testimony of his relatives is not effective enough."
