Chapter 310 - 310 278 Capture

310: Chapter 278: Capture 310: Chapter 278: Capture The group of police officers in the small meeting room, reminiscent of nervous interviewees, naturally paired up, formed groups, and voluntarily elected a leader to start discussing the division of provinces.

Eventually, two groups unexpectedly merged, focusing solely on the data from their own province, while other groups no longer divided the work by province, but instead, a single group took responsibility for several provinces.

Throughout this time, Yu Wenshu simply observed, without the need to utter an extra word.

Wei Zhenguo and others from the county bureau watched on, feeling somewhat emotional.

This office-like way of working seemed to be something that only urban bureau levels like the provincial capitals could pull off; the detectives at lower levels still preferred traditional methods.

“I’ll write the criminal profiling,” said Liu Jinghui, who was quite familiar with the Changyang City Bureau; seeing them get into work mode, he turned around to attend to his own tasks.

With days spent not working, comfortably at home, and the wife and kids having run off to the grandparents’ house, one does start to yearn to return to the workplace, to regain that long-lost sense of achievement.

Jiang Yuan had someone retrieve all the physical evidence related to the case and began examining each item.

Now that it was confirmed to be the act of an ex-convict, if they could obtain a fingerprint from the murderer, the case would become much easier to solve.

Most cases are like this, especially those with more intense conflict, such as fights or rape.

Logically, the perpetrator ought to leave behind a swath of physical evidence.

For example, fingerprints, semen stains, hairs, or dandruff; or perhaps skin tissue, blood, etc., left behind due to the victim’s resistance.

But the murderer in this case was quite unique.

Perhaps due to his poor physical condition and lack of confidence in his self-control, his initial action was to stab with a dagger.

Jiang Yuan could tell from the bloodstains at the scene that the murderer approached the victim from behind and delivered several stabs to the back, causing the victim to fall to the ground.

Significant blood loss would incapacitate the victim, causing them to lapse into unconsciousness or a semi-conscious state.

It was only then that the perpetrator carried out the rape and abuse, and notably, he calmly wore gloves for the act.

Even after the deed was done, he even washed away the areas he had bitten, leaving only bite marks and no usable DNA.

This cool demeanor not only indicated experience from a former criminal but also suggested abnormal mental states—

Liu Jinghui’s bold assertion that the criminal was an ex-convict was a very daring judgment.

Reasonable, but extremely bold.

If Jiang Yuan was handling this case alone, he wouldn’t have initially suspected an ex-convict; he might have followed leads related to mental instability and height.

Moreover, Jiang Yuan felt that focusing on the detail of the slippers could also yield a breakthrough.

After all, cheap slippers are often made by small factories, whose products tend to have a limited distribution range.

On the other hand, the financial struggles of the murderer were another clue.

Living a life of crime is highly challenging and demanding, and most criminals can’t manage it.

This guy was likely looking for work and places to live near the crime scene.

As Jiang Yuan pondered how to filter out the murderer, the officers from the provincial group started cheering.

Everyone looked over, and someone asked, “Did you find someone?”

“We did!” The elected leader of the reorganized group, a sharp 30-year-old officer, responded before immediately adding, “It’s someone from our Shannan Province.”

Yu Wenshu and the others had been feeling emotional, but now they all gathered around.

A major clue in the case was indeed exhilarating, and Yu Wenshu and the others were also extremely pleased, yet this kind of happiness was markedly different from solving the case.

And he was very clear that the so-called “finding” in front of him truly had the potential to break the case.

Thinking of this, Yu Wenshu, the squad leader, couldn’t help but swallow.

An old hunter who’s been on many hunts will gulp when he sees an elk entering his range.

An old fisherman who’s caught many fish will gulp when he sees a net full of fish, shrimp, and crab.

An old criminal detective who’s worked on many cases will gulp when he sees another murderer about to enter the death penalty process.

The selected police officer, looking sharp and capable under everyone’s gaze, spoke steadily, “Based on large-scale data modeling, we reviewed the list of released prisoners from the previous year before the incident occurred and found a suspect from Shannan Province named Qiao Maishou with a major likelihood of committing the crime.”

He glanced at his notebook and said, “Qiao Maishou, a resident of Shannan Province, 27 years old, was 25 at the time of the crime, and stands 156 centimeters tall.

At the age of 13, Qiao Maishou was sentenced to three years in a reformatory for robbery and theft.

He received an additional one-year sentence for violating prison regulations.

After being released, he was again sentenced to 5 years for robbery.

He was 23 when released, then returned to his hometown.

He served six months of detention for participating in group gambling.

By the time of the incident, he had been free for eight months after completing his sentence.”

Liu Jinghui, who had been listening, already stood up, clapped his hand, and said, “Spent his teenage years in prison, lived in prolonged confinement, unable to interact normally with others…

Also, his violation of prison regulations shows he couldn’t adapt to living within prison.

With that, it’s very easy to lead to personality distortion and strange character traits.”

He was no longer just thinking about catching someone; he was even more hoping that his portrayal of criminal behavior would guess the killer right.

The officer who had narrowed the search to the killer was also invigorated, adding cooperatively, “Exactly, three months after being released, Qiao Maishou again got into a conflict with someone and was taken into the police station.

Afterwards, he returned to his hometown for a while.

Two weeks before the crime occurred, he took a high-speed train to Changyang City.

He spent most of his time in internet cafes near the scene of the crime, and on July 2 he checked into a small hotel near the train station for a week…

He returned home on July 10 and is currently serving a sentence in Yunchang City Prison for theft…”

With current criminal investigation methods, it’s incredibly simple to obtain someone’s trajectory.

Basically, knowing the identity card number is enough to know the transportation they took, the places they stayed.

Perhaps Qiao Maishou didn’t understand this, or he hadn’t paid much attention, leaving traces everywhere.

However, it’s not easy for a person to really be careful not to leave any traces.

The fact is, when there were no clues pointing to Qiao Maishou, these traces he left didn’t matter.

But once his existence was discovered, almost all the evidence pointed to him.

Yu Wenshu no longer had any doubts and laughed openly, “Great, we can even skip the arrest process.

Tang Jia, get the materials sorted out, and let’s proceed with the process quickly…”

Tang Jia immediately responded with affirmation.

Yu Wenshu then looked at Jiang Yuan and Liu Jinghui.

Truth be told, he was more familiar with Liu Jinghui, having often asked for his assistance in the past.

However, most of the time, his need for Liu Jinghui was advisory in nature – that is, to ask Liu Jinghui for suggestions and to guide the direction of case-solving.

Most of the provincial police chiefs also preferred this mode of cooperation; it was easier for them and easier for the local authorities.

Back then, Yu Wenshu only considered Liu Jinghui as an ordinary senior police chief.

But this time, the collaboration between Liu Jinghui and Jiang Yuan produced an effect that far exceeded Yu Wenshu’s expectations.

To put it bluntly, it exceeded everyone’s expectations.

“So, does this mean this case is settled?” Liu Jinghui pushed a stack of files.

Yu Wenshu gave an affirmative “hm” and laughed, “No wonder you two got high marks on this case, next…”

“I’m so hungry,” Liu Jinghui moaned, rubbing his stomach.

“Let’s eat first, let’s eat first,” Yu Wenshu warmly beckoned as if inviting a respected elder to join him for entertainment.
