Captain Lu was aloof again today.

Chapter 61 Profile
Bai Rushuang opened her mouth, but couldn't utter a single word. She felt as if a wad of cotton was stuck in her chest, making her feel suffocated.

She remained silent, her eyelids lowered.

She thought she could now understand why Lu Jingming was so infatuated with Wei Qingsong; it wasn't just because of her captivating beauty, but also because of her calmness and wisdom.

Despite her pride, she had to admit that she was inferior to Wei Qingsong in every respect.

The car had already left the city, and dusk was falling. The trees on both sides of the road were lush and leafy, their branches and leaves swaying wildly in the darkness.

Wei Qingsong withdrew his gaze, paused for a moment, and said calmly, "Regarding this case, I currently have four findings."

"First, the murderer is a local, around 30 years old, single, very familiar with the roads and traffic, and has his own means of transportation. I initially speculate that his occupation is most likely a driver, courier, food deliveryman, or someone who knows the road environment of Quyang County like the back of his hand."

"Secondly, the murderer's feelings toward women were very complex, including both hatred and sexual desire. He must have suffered severe emotional trauma in the past two years. When we found him, we were sure to find a large number of pornographic magazines in his home."

"Third, all four victims were wearing black pencil skirts when they were murdered. This was a symbol and a sign to the killer. He had a strange fascination with women who wore black pencil skirts. There must have been a woman in the killer's love life who liked to wear black pencil skirts and had a very special meaning to him."

"Fourth, on August 22, the day the third victim, Jiang Keying, died, the murderer experienced a great setback. I personally believe that his sense of frustration stemmed from his work."

Bai Rushuang was stunned for a moment before she reacted and asked in confusion, "I can understand the first three points, but how did you arrive at the fourth point, 'profile'?"

The four victims were found in sparsely populated suburban roads, far apart from each other, more than ten kilometers away from the central urban area of ​​Quyang County. Therefore, it is reasonable to assume that the murderer had a means of transportation and was very familiar with Quyang County.

But why would they say he suffered a setback on August 22nd? Bai Rushuang couldn't understand.

“The most distinctive feature of a serial killer is that they are ‘fixed’ – they have fixed targets. All four of our victims were wearing black bodycon skirts and were single, unmarried women around 30 years old.”

"The killings occurred at a fixed time; all four victims were injured between 9 and 11 p.m.

“There is also a fixed method of killing. Apart from Jiang Keying, the other three victims all died from strangulation. All four victims were violated after death.”

“The only exception is Jiang Keying, who died from blunt force trauma to the head.” Wei Qingsong picked out Jiang Keying’s autopsy report and held it up in his hand. “Moreover, it was caused by multiple blows. What does that represent? It represents anger.”

"Then, could it be that Jiang Keying said something that angered the murderer, which led to the murderer assaulting her?" Bai Rushuang cautiously raised another possibility.

Lu Jingming curled his fingers and tapped the back of the chair lightly: "Turn six pages back on the computer and start reading from the third line."

Bai Rushuang was stunned for a moment, then subconsciously did as instructed.

Scroll back six pages and the mouse cursor hovers over a line of black text.

"...According to our investigation, the deceased, Jiang Keying, was 30 years old, a music teacher. She was gentle, kind, rarely argued with anyone, and had harmonious relationships with her neighbors and colleagues." Bai Rushuang read aloud, then suddenly realized something and stopped speaking abruptly.

Why would someone who is generally considered to have a good temper say something that would provoke the murderer?
Wei Qingsong raised an eyebrow at Lu Jingming and continued, "So, on this day, the murderer must have encountered something very unpleasant. He was full of anger and eager to vent his resentment. Therefore, his method of killing changed only when he murdered the victim Jiang Keying, because he was venting his anger."

"Then, on August 27, he committed his fourth crime. This close timing suggests that the source of his anger had a significant impact on him. Therefore, I believe that his anger stemmed from his work, most likely from unemployment, wage deductions, demotions, or being scolded by his boss and clients."

Bai Rushuang suddenly understood: "So that's how it is, Miss Wei, you're really amazing."

But soon, she sighed with a bitter face: "But, according to what you said, this range is too broad. Around 30 years old, single, working as a driver, courier or food deliveryman, womanizing... Looking at the whole Quyang County, there are countless people like that. How are we supposed to find them?"

Wei Qingsong pondered for a moment, then pulled out another sheet of paper from the pile of documents in his hand and carefully looked through it: "During your investigation of the first victim, Yu Fangfang, did you make any special discoveries?"

Bai Rushuang frowned, deep in thought.

Lu Jingming tapped the back of the chair again, his voice deep and powerful: "The data on the computer, turn back twelve pages, to the seventh line."

Before Bai Rushuang could make a move, 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 a delivery. According to his statement, he was sleeping at home that night. There was no one to testify, so he did not have a clear alibi. Why didn't the Quyang police continue to investigate him?"

Bai Rushuang hurriedly flipped the document to the page Lu Jingming had mentioned. Starting from the seventh line, it clearly contained the details of the police investigation into Zhang Ming.

She was speechless. For some reason, she felt that Lu Jingming and Wei Qingsong were a match made in heaven.

One has a photographic memory for case files, possesses extremely keen judgment, and is exceptionally skilled, while the other excels at deducing the killer's psychological state from minute details and creating accurate profiles.

What a wonderful and perfectly matched combination!

It took Bai Rushuang a long time to come back to her senses. She said with a sour tone, "We did investigate Zhang Ming back then. Although he didn't have an alibi, he didn't have the means to dispose of the body because he only had a delivery tricycle with very conspicuous markings on the vehicle."

"The security guards in Zhang Ming's residential community can testify that the delivery truck was parked at the entrance of the community that night and did not leave."

Wei Qingsong pondered for a moment, then asked, "What about his immediate family members? Do they have cars?"

“Uh…” Bai Rushuang hesitated for a moment, then stammered, “Zhang Ming’s father does have a car, but he insists that he did not lend the car to Zhang Ming that day.”

Upon hearing this, Lu Jingming's gaze darkened slightly, and he said coldly, "Where is the evidence? The testimony of relatives alone is not enough."
