The crackdown on organized crime began with the arrest of the mother-in-law.

After seeing Zhou Xuexi off, Qin Chuan re-entered the scene.

This time, Qin Chuan surveyed the courtyard from outside, inch by inch, until he reached inside.

Criminal investigation scene examination is a skill that every criminal police officer must master.

All clues to solving a case come from the crime scene.

Qin Chuan had heard about this massacre of an entire family in his previous life.

The newlyweds were murdered in their home on the second day of their marriage and subjected to all kinds of humiliation. Such cases are impossible to keep quiet about.

There were many versions of the rumors back then, and Qin Chuan still remembers a few of them to this day.

However, no matter which version Qin Chuan remembered, it was not even one-tenth as cruel as the scene.

The living room was where the victim was ultimately killed, but that doesn't mean it was the only place where the murderer committed violence.

Traces of these things can be found in the bedroom, kitchen, and even under the jujube tree in the yard.

However, the case was not solved back then.

At least when Qin Chuan was imprisoned, no criminal suspects were apprehended.

Qin Chuan completed the on-site investigation at around 9 p.m.

It was completely dark, but there were still quite a few people watching.

Qin Chuan used the Eye of Evil today to exclude the villagers who were watching.

No major discoveries were made.

Although there were a few petty thieves, none of them were involved in this case.

"Captain Qin, what should we do now?"

In the conference room, Lu Zhiguo, Sun Haomin, and Dong Houde were present, along with some key personnel from the three squadrons and a forensic doctor.

A case analysis meeting is currently being held. All of the people involved have been to the scene and are shocked by the brutality of the murderer. They all look quite grim.

Before Song Hui was arrested, the criminal investigation team had investigated murder cases, some successfully and some unsuccessfully.

The lesson learned is that you should do whatever the team leader tells you to do.

Qin Chuan sat at the head of the table. After a day of investigation, he had actually found quite a few clues at the scene.

On the contrary, there are many more.

There was much more than Qin Chuan had imagined.

"Let's analyze the situation on site first."

After a moment's thought, Qin Chuan began to review what he had learned from today's site survey.

"First, the number of murderers."

"Judging from the situation at the scene, there should be four people."

"Captain Qin, is it based on the number of footprints?"

Sun Haomin raised a question.

Qin Chuan shook his head: "When we arrived, quite a few people had already gone inside."

"According to the person who reported the case, who is also the mother of the male victim, she discovered that her son and daughter-in-law had been murdered when she went to deliver chicken soup to them at noon."

"Afterwards, the person who reported the incident fainted due to extreme shock."

"After I woke up, I called the police and also called my husband at home."

"After receiving the call, the male victim brought four or five people from the village with him to the scene."

"So, by the time we arrived, the footprints at the scene had been almost completely destroyed."

"My judgment that the four people committed the crime is based on the bruises on the male victim's eyelids."

Qin Chuan possesses criminal investigation skills that are rewarded by the system, allowing him to reconstruct the crime scene to a certain extent by examining factors such as injuries on the body and the surrounding environment.

"The male victim had multiple bruises on his eyelids and signs of being beaten."

"This shows that the murderer had forced the male victims to watch their wives being humiliated."

"The scars on the eyelids are from people who didn't want to look at the eyes but were forced to."

"And the female victim's wrists, both wrists had bruises of varying degrees."

"The footprints in the pools of blood on both sides of the coffee table indicate that two people controlled the female victim during the assault."

"To facilitate the perpetrator's assault."

"One person committed the assault, two others restrained the female victim, and one person restrained the male victim who was tied to a chair..."

There are at least four perpetrators!

Qin Chuan explained it in great detail, and described every single detail very clearly.

This left Lu Zhiguo and the others somewhat bewildered.

How did you manage to see so many details from just a few bruises?

Were we fake police officers?

"Furthermore," Qin Chuan frowned, reviewing every detail found at the scene, "the murderer and the victim likely knew each other."

Ok?

"Captain Qin, you said they...know each other?"

Lu Zhiguo was determined to follow Qin Chuan to the end, but he really couldn't understand why Qin Chuan said that the murderer and the victim knew each other.

How could a human being be so ruthless?

Qin Chuan, however, had his own judgment.

"Two reasons."

"First, the victim's house was newly built, and the courtyard wall was very high, which ordinary people could not climb over. Moreover, did you notice that the courtyard wall was filled with broken glass or wine bottles to prevent people from climbing over it?"

“Hmm,” Dong Houde was meticulous. After arriving at the scene, he walked around the house. “I walked around the wall, and the fragments on the wall were all intact and undamaged. The other party did not climb over the wall to get in.”

In rural areas, there's a custom of putting glass shards on courtyard walls to prevent thieves from climbing over them.

To get in, you'd have to lay down a blanket or something, but that would leave marks.

"Secondly, there were no signs that the door lock had been knocked on."

Qin Chuan had just drawn the lock-picking skill from the system, so he could tell at a glance whether a lock had been opened abnormally.

Lu Zhiguo suddenly realized that he had seen Qin Chuan peering through the door for a long time that afternoon; it turned out he wanted to see this.

Sun Haomin also figured out why Qin Chuan made this judgment.

“The incident happened at night, so the victim’s family would definitely have locked the gate.”

"The other party did not climb over the wall or pick the lock, so the only way to explain it is that the victim opened the door from the inside."

"The victim opened the door in the middle of the night, so they must know the other person."

Qin Chuan nodded: "Therefore, our investigation should start with the people the deceased knew."

"Village?"

Qin Chuan didn't have much hope for Lu Zhiguo's suggestion.

There are two reasons. First, he had seen through the lens of evil that there were no suspects among the villagers who were watching the commotion today.

Generally speaking, if the crime is committed by villagers, the perpetrators are very likely to come and watch when the police arrive.

They wanted to see if the police would find anything.

However, there were no suspects among the onlookers.

Secondly, there were four murderers.

In one village, four people committed the crime...

The risks involved are far too great.

However, the villagers had no choice but to investigate.

"In that case, the First Squadron will focus on investigating the village."

"Does the victim or his parents have any enemies in the village, or people with whom they have had recent conflicts?"

"The other team, the Second Squadron, will check the victim's phone call records, bank transfer information, etc."

At the crime scene, there were signs that the victim's home had been ransacked, so it's possible the perpetrator was after money.
