Captain Lu was aloof again today.

Chapter 23 Heartbroken
It was already past midnight, and the cool sunlight pierced through the dark clouds, leaving hazy dappled patterns on the long conference table.

Wei Qingsong laughed: "Sometimes a person's obsession will accompany them for a lifetime. If it is not resolved, they will only sink deeper and deeper."

"Li Yundong's personality is extremely paranoid. He hates his parents but is unable to take revenge. He can only transfer his hatred elsewhere. Even so, the root of his hatred is still his parents. Whether it is taking Yang Yan to a guesthouse that is only a hundred meters away from his parents' residence, or after killing Yang Yan, he throws the murder weapon and head into the community where his parents live, it gives him a sense of revenge."

“I don’t know if you noticed, but when he was so certain that we couldn’t find any evidence, the confident smile on his face was genuine and heartfelt. It was the first time Li Yundong had smiled so brightly during the entire interrogation. At that time, he was about to face 24 hours of summons and detention. So, when I think back to that smile, I feel that there might be a deeper meaning behind it.”

After listening to her analysis, Chen Jin exclaimed in astonishment, "Sister Wei, you are truly amazing!"

Back when Wei Qingsong left without saying goodbye, she was a beautiful and youthful college student at Tangzhou Normal College. Her daily life consisted of either thinking about where to go shopping for new clothes or where to eat and get her nails done.

After six years apart, she had become such a seasoned criminal psychology expert.

Life is truly full of surprises; no one knows what will happen next.

After saying that, he realized something and quickly shut up, secretly glancing at Lu Jingming.

Faced with such meticulous psychological analysis, Lu Jingming remained expressionless. His eyes seemed shrouded in mist, and no one could penetrate the fog to discern his thoughts.

He looked at Wei Qingsong with a meaningful gaze.

While studying criminal investigation at the Public Security University, he also took a course on criminal psychology, learning some of the dry theories superficially, which actually had little effect on solving cases.

Unlike his superficial, theoretical learning, Wei Qingsong is clearly an excellent criminal psychologist. Such analysis and judgment cannot be accomplished simply through data and theory, but requires real practice and experience.

In the files within the municipal bureau system, Wei Qingsong's resume is actually very simple and clean, only two pages long. She studied psychology and criminal psychology at a well-known university in Y country, and her teacher was an internationally renowned veteran criminal psychology expert.

During her studies, she attended many seminars on criminal psychology and participated in several FBI case profiling sessions as a teaching assistant.

But she is, after all, just a 26-year-old young woman, and a newcomer to the field. Is her ability to make such insightful analyses due to her exceptional talent, or is it for some other reason?
He and Wei Qingsong met when they were ten years old. At least, during the ten years they knew each other, Wei Qingsong never showed the slightest interest in criminal investigation or crime.

On the contrary, she often complained about Lu Jingming, who came from a family of criminal police officers.

"You have to deal with criminals every day, it's so dangerous, do you really have to become a policeman? You absolutely can't let me become a widow."

When filling out his college application, Wei Qingsong struggled for three whole days before finally choosing the teachers' college next to the Public Security University.

"Forget it, my fragile heart can't bear those bloody and violent cases. I'll just apply to the teachers' college across from your school. The two schools aren't far apart, and I'll be checking up on you anytime. Don't even think about having any fun in college."

Wei Qingsong, who used to be terrified and avoid violent crimes, can now confront such cruel crimes and calmly analyze the psychology of the criminals.

What changed her during the six years he was absent?
Lu Jingming was somewhat afraid to think about it.

He felt a pang of heartache for her. Someone as wonderful as her shouldn't have been exposed to darkness; she should have lived in the sunlight, carefree and without worries.

……

After analysis and examination by forensic personnel, numerous biological reactions of Li Yundong were found on the recovered evidence.

Forensic examination confirmed that Yang Yan suffered a severe blow to the head, resulting in a fractured skull. This was the true cause of her death, and the murder weapon was the iron hammer.

The investigation revealed that the hammer was originally kept in the storeroom of the Red Star Guesthouse, and the owner was unaware that his belongings were missing.

This left the police speechless. If it weren't for the guesthouse owner's oversight, the case would probably have already yielded clues, so why go through such a roundabout way?

In accordance with the provisions of the Public Security Administration Law, the police gave the owner a stern verbal warning and ordered the Hongxing Guesthouse to suspend business for rectification. From now on, strict identity registration will be required, otherwise it will be shut down according to law.

The interrogation room door opened again.

This time, Li Yundong had nowhere to escape.

His demeanor remained remarkably calm, and even when recounting the process of his murder, his tone remained completely even.

"She's getting more and more crazy. She's actually forcing me to divorce my husband so we can be together. She's even threatening me that if I don't divorce him, she'll expose my cat abuse."

Chen Jin paused for a moment and asked him, "Does Yang Yan know you're abusing cats?"

Li Yundong did not answer, but instead gave a mocking sneer.

Wei Qingsong looked up at him and said calmly, "Yang Yan was deeply attracted to you because she witnessed you abusing cats, right?"

"She saw another side of you that no one else knew, and was attracted by your strong sense of mystery and contrast, even becoming infatuated. But she didn't know that to you, she was just a woman who came to your door. You only treated her as a plaything, and besides abusing cats, she had another kind of entertainment."

In short, it's about two morbid people meeting; they can't survive without going mad.

Yang Yan probably never imagined that she was suffering from a pathological mentality and wanted to find solace, but unfortunately Li Yundong was already terminally ill and incurable. Coldness, ruthlessness and tyranny had already seeped into his blood.

The cold handcuffs were locked on Li Yundong's wrists, and he would face legal punishment.

After working all night, everyone was exhausted. Director Wang greatly appreciated their speed in solving the case and generously gave them half a day off to rest.

Although half a day off seems too stingy, it's better than nothing.

After leaving the interrogation room, Wei Qingsong never saw Lu Jingming again. After searching in vain, she walked out feeling dejected.

At the main entrance of the Municipal Public Security Bureau, several young men were carrying a wheelchair up the steps.

A middle-aged woman sat in a wheelchair. She was thin and hunched over, with strands of silver in her dry, yellow hair. She looked to be about fifty years old, but her face was already covered with wrinkles.

Wei Qingsong kindly stepped forward and asked, "Do you need any help?"

A thin, dark-skinned young man replied, "Hello, comrade, we are Yang Yan's family members. We would like to ask how the investigation into her case is progressing?"

Wei Qingsong was slightly taken aback and subconsciously looked at the haggard middle-aged woman.

Is this Yang Yan's mother who suffered a stroke in Danzhou?

Yang's mother stretched out a trembling hand, her words slurred, tears streaming down her deeply lined face: "Yan... Yan, my daughter."

"I'm sorry, my aunt had a stroke and her speech isn't very clear. We were supposed to be the younger generation, just a few of us, to handle my cousin's funeral arrangements, but she insisted on coming along." The young man, his face slightly flushed, scratched his head and explained.

Wei Qingsong looked at Yang's mother, her feelings somewhat complicated.

As a mother, she was tormented by illness to the point of being unrecognizable, yet she still traveled a long distance from Danzhou to see her daughter.

However, as a mother, she did not give Yang Yan enough love when Yang Yan was young, which led to Yang Yan developing such a pathological mentality and indirectly caused Yang Yan's tragedy.

Yang's mother's love seemed to have come too late.

I updated two chapters today, so I'm confidently asking for your votes.

These two chapters have brought the first case to a close. The previous hints and foreshadowing regarding Songsong's past have been in place, and will gradually unfold in the next case.
