As Li Ang had guessed, the final perpetrators of the case were indeed the father-in-law and mother-in-law who lived with the deceased.

While their son was away working, the father-in-law had been making unwanted advances towards the deceased, repeatedly coercing her.

The deceased sought help from the mother-in-law, but the latter, wanting to "keep the family scandal under wraps," remained tacitly complicit, even colluding with her husband to imprison their daughter-in-law.

During one instance of abuse, the deceased threatened to tell her husband, who was about to return from working, everything. Panicked, the father-in-law and mother-in-law strangled her to death and tried to escape responsibility by staging it as a suicide by hanging.

In the process, they dared not look directly at the corpse's unclosed eyes, and even specially used cloth to cover her face.

Watching the two elderly perpetrators on the TV program, their faces pixelated, tearfully confessing in prison, Li Ang couldn't help but sneer, "These people are so ridiculous."

"Hmm?"

Wang Fengnian cast a questioning glance.

Li Ang spread his hands. "I don't think their tears are a sincere repentance.

During the commission of the crime, they had countless opportunities to stop harming the victim.

Did they stop? No, they didn't.

The tears shed by criminals who actively harm the innocent, after putting on prison clothes, are only regret for being caught doing evil, and fear of the impending punishment.

Scum is always scum."

Wang Fengnian nodded noncommittally and asked, "Little Li, you have good reasoning skills. Shanshan said you used to read a lot of detective novels?"

Of course, Li Ang couldn't tell him that he had used the Xinhua Bookstore to read a lot of reasoning when he was in junior high school,

And began to use the Internet to learn a series of books such as "Criminal Science and Technology," "Criminal Investigation," "Trace Inspection," and "Investigative Jurisprudence" {online electronic versions, physical versions are also sold}

Immediately, he nodded with a smile, "Yes, my childhood dream was to become a nemesis of crime, maintain social order, and protect the lives and property of the people."

"Yes."

Wang Fengnian nodded, suddenly remembered something, and went back to the room to get a few documents.

These documents were all cases recently received by the Yin City official. In recent months, all kinds of strange things have happened one after another, making the grass-roots cadres overwhelmed.

An front-line cadre like Wang Fengnian hasn't been home for a long time and had a normal meal with his family.

He took out more than twenty photos from the file bag. "What do you think of these photos?"

Li Ang took the photos and found that the crime scene in the photos was located in an ordinary residential building.

In the two-bedroom and one-living room, the male and female owners were lying dead on the floor of the living room, with several deep knife wounds on their waists and abdomens, and a large pool of blood accumulated around the bodies.

All the cabinet doors in the room were opened, and some sundries were piled on the sofa. There were no bloody footprints or other blood stains on the ground.

The murder weapon was located in the narrow, lighted bathroom. It was a steel steak knife with a short handle and a smooth, curved blade, soaking in the sink.

Below the light switch box on the right side of the sink, there was a string of dripping blood stains.

Li Ang looked at the photos and asked without raising his head, "Burglary?"

"Yes."

Wang Fengnian nodded, "A fire escape ladder was erected outside the window. The murderer sneaked into the house at night and murdered the homeowner during the robbery. The entrance and exit were just located in the monitoring blind spot, and his appearance was not captured."

"Hmm..."

Li Ang tapped the photo lightly with his finger and said, "How long has this case been?"

"Two days ago."

Li Ang put the photo on the table and said, "I can't be sure, but I suggest going to the nearby hospitals and clinics in the area where the incident occurred to check the recent admission records,

Check if there are any patients with a deep wound on the palm of their right hand."

"Oh?"

Wang Fengnian frowned, "Why?"

Li Ang spread the photos on the glass coffee table with fruits and tea, and pointed to several photos,

He said, "The toilet in this house is quite narrow and dark, especially the light switch box, which is located on the right side of the sink near the wall.

The only bloodstain here is below the light box, and the blood dripping trajectory is vertical.

This shape of bloodstain is obviously dripped on the ground when the suspect pressed the switch.

The light switch box is located on the right side of the sink, which determines that it is difficult for normal people to put their left hand in to press the switch, and can only use the right hand, indicating that the blood comes from the suspect's right hand palm."

He glanced at Wang Fengnian and smiled, "So, does this blood stain come from the suspect himself? Or from the victim?

I'm more inclined to think it's the suspect's own blood.

If it is the blood stain that the murderer got from the victim, then the trace of blood dripping should be from top to bottom, from thick to light;

And the concentration of these blood stains on the scene is the same up and down, it can only be caused by the suspect's own hand injury.

According to the shape of the steak knife, I guess that when the murderer committed the crime, because the handle of the steak knife was short and the blade was long,

When holding the handle tightly and stabbing forward, due to excessive force, the blade countered the palm and cut the suspect's right hand.

As for the fact that there are no blood stains at the crime scene, and all the sundries are piled on the sofa...

I guess the murderer went to the bathroom to deal with his hand urgently, then returned to the living room to wipe the blood stains on the ground, and then fled the crime scene.

Finally, according to the amount of blood under the light switch box,

I guess his hand injury is quite serious and he must go to a professional institution, that is, a hospital or clinic for sutures.

As long as you check whether there are any patients with cut marks on their right palms recently, it will be easy to screen them out."

After speaking, Li Ang looked at Wang Fengnian's calm face and smiled: "Uncle Wang, you must have found out through the test that the blood belongs to the third party in the room, that is, the suspect himself.

As long as there is a dna sample, it is only a matter of time to arrest the criminal suspect."

Li Ang also hid a sentence that he did not say, that is, he speculated that strange events had occurred on a large scale in Yin City recently—

This burglary and murder case is actually quite simple.

Even if you don't follow Li Ang's speculation to go to hospitals and clinics to investigate, or search according to dna samples, the official can also find the murderer by relying on a large amount of manpower by checking the monitoring data on a large scale.

Generally speaking, murder cases must be solved. This case has passed for two days, which is enough to prove that the official manpower in Yin City is likely to be stretched.

Is this situation caused by the extraordinary factors randomly generated by the killing game,

Or is there another reason?

Li Ang still maintained a calm smile on his face, and thoughts kept pouring into his mind.
