Old Bai has been in the police force for over thirty years and has seen all kinds of bizarre cases in that time.

But a father-in-law killing his daughter-in-law and his son taking the blame for it was something he had truly never seen.

"Why?"

Old Bai asked the question everyone would ask.

Liu Guodong worked late with Lu Chuan yesterday and hadn't rested well, so he let out a long yawn.

"Why else, just the usual family squabbles."

This morning, Wang Yishan called Liu Guodong and explained the case in detail.

In all these years, it was also the first time Wang Yishan had encountered such a case.

"Wang Hui's parents were kicked out by their daughter-in-law five years ago and now rent a place to live."

"But the old couple's retirement pension cards are held tightly by the daughter-in-law, leaving them without a source of income, so every now and then they go to Wang Hui for living expenses."

"Wait a second!"

Listening intently, Yang Sen stood up and interrupted Liu Guodong: "Why is the old couple's retirement pension card with the daughter-in-law?"

"What's there to question, Wang Hui is soft-hearted and tightly controlled by his wife, who threatened the old couple that if they didn't give her the pension card, she'd divorce Wang Hui."

"Then let her divorce?"

"It's not as simple as you say. Wang Hui has been married for seven years and still has no children. It's said he can't have children, and his wife is using this against him."

"Moreover, when Wang Hui got married, the bride price was over three hundred thousand yuan. If they divorced, you know his feisty wife wouldn't return the bride price."

"I heard from Captain Wang that Wang Hui's family often gets into fights. If they can fight, doesn't it mean Wang Hui isn't as meek as he seems?"

Lu Chuan was at the scene yesterday and learned some basic information.

"Not at all. The fights were all started by Wang Hui's wife, and sometimes it wasn't just Wang Hui who got hit; his wife also often hit Wang Hui's parents several times."

"The night before last, Wang Hui's father went to Wang Hui for money, but Wang Hui wasn't home. The old man wanted the pension card and got into a conflict with Wang Hui's wife."

"Wang Hui's wife grabbed a kitchen knife, threatening to cut Wang Hui's father. In the struggle, Wang Hui's father got desperate, grabbed the knife, and chased Wang Hui's wife for more than half an hour."

"Later, when Wang Hui came back, he told his father to leave and said he'd handle things, then called the police to say he killed his wife."

Old Bai let out a deep sigh.

Such things aren't common, but they're not rare either.

Two years ago, there was a disappearance case in the High-tech Zone.

The husband reported it; the wife was missing.

A police officer from the police station searched for a week without finding any clues.

Moreover, their neighborhood was a gated community, and the surveillance camera at the exit didn't capture any video of the wife leaving.

In such a limited area, a living person just disappeared.

Later, the water supply to the reporter's home was suddenly cut off, but the pipelines were fine. When the property management came to check, they found out that the family had bought water only half a month ago and thought the water meter was broken.

During repairs, they found the water meter was fine, and this fact was noticed by the police officer conducting the interviews at the time.

It was later discovered that the wife had not gone missing at all but was killed by her husband at home.

When he committed the murder, their child was sleeping in the next room.

More unbelievably, the husband completely dismembered the body, even grinding it into small pieces with a meat grinder and flushing it down the drain.

This was why their water usage had increased significantly.

Later, the detectives handling the case dug up the entire drainage system and the septic tank within the neighborhood.

In several tons of waste, human tissue was detected.

Only then was the murder confirmed.

This event led to a significant drop in house prices in that neighborhood, especially in that building.

Initially, the apartments could sell for twenty to thirty thousand yuan per square meter, but later, even three thousand yuan per square meter found no buyers.

Who would dare? Just the thought that the sewers were filled with... ground up remains is enough.

Today, we encounter another case of a father-in-law killing his daughter-in-law.

Ultimately, all triggered by family disputes.

The suspect confessed, and the specifics of the case were mostly figured out, but Lu Chuan's work needed to continue.

The evidence collected by the crime scene investigation needed further analysis.

Because no one could be sure that what Wang Hui's father said was the absolute truth.

Evidence has proven time and again to be more credible than words.

Lab.

"Master... the blood types don't match."

There were two types of blood collected from the scene.

The first type was O blood, belonging to the victim.

The second was A blood, theoretically belonging to the culprit.

Wang Hui was excluded from suspicion because his blood type was AB, which didn't match the blood type found at the scene.

However, Wang Hui's father's blood type also wasn't A; it was B!

"Also, the footprints don't match either."

The two sets of footprints collected by Lu Chuan next to the blood pool in the bedroom, after preliminary analysis, were from a woman, not a man.

As for the deceased, she had already been chopped to death on the bed and couldn't possibly step into her blood pool.

So, whose footprints were they?

Whose blood type was A?

The answer was clear!

Wang Hui's blood type is AB, his father's is B. Given the hereditary nature of A-type blood, in the absence of a rare genetic mutation, where did Wang Hui get his A-type blood genetics from?

"The killer... is Wang Hui's mother?!"

The latest developments from the crime scene investigation were immediately communicated to the Water District Criminal Investigation Team.

Wang Yishan looked at the blood type and footprint analysis report sent by Liu Guodong and suddenly felt the world was not very friendly to him.

Think what you may, but evidence doesn't lie.

"Task Force One, head out to Hengyuan Community!"

Hengyuan Community is a self-built housing area, mainly inhabited by migrant workers doing odd jobs in Haizhou City.

The living conditions are average, but the rent is cheap; a single room only costs three hundred yuan a month.

When Wang Hui's parents were kicked out, he rented a small single room there with his own private savings.

In a small room of less than twenty square meters, there isn't even a window.

When Wang Yishan arrived, Wang Hui's mother was on the floor packing cardboard boxes.

This was the main source of income for the old couple, as their son didn't have spare money every month.

They couldn't get the living expenses from the daughter-in-law every month either.

Watching the old woman on the floor tying up the cardboard with effort, Wang Yishan's feelings were extremely complicated.

"Take her away!"

The detectives following Wang Yishan exchanged looks, a bit at a loss.

They hadn't encountered such a scene before.

"I'm the one who killed her, but can you wait a bit? I just have a little more cardboard to pack, only three more minutes."

Wang Hui's mother spoke very calmly as if she had no idea what awaited her.

She also forgot that with her daughter-in-law dead, she could take back her retirement pension.

She wouldn't even need to collect cardboard anymore.

The subsequent interrogation went very smoothly.

Most of what Wang Hui's father said was true; only the perpetrator was Wang Hui's mother.

On the day of the incident, Wang Hui's mother went to the East Garden District first, followed by Wang Hui's father.

When he arrived, he happened to see his wife killing their daughter-in-law.

With that, the case was settled.

Lu Chuan didn't know how this case would be judged.

Whether Wang Hui's mother would receive the death penalty or not was uncertain.

But no matter the outcome, it was a sad story.

Or rather, a tragedy.

Wang Hui and his father concealed the true details of the case, not just once but twice, and according to the law, they would also bear the corresponding responsibility.
