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

Chapter 764 Overall Control, Detailed Analysis

Chen Jianguo took a cigarette from the cigarette pack on the table, lit it, and continued his analysis.

"Another point is that the victims, especially the female victims, had been assaulted before their deaths, and the male victims had been tortured before their deaths. From this perspective, if the perpetrator was only after money, was there any need to torture the male homeowner? Was it to force him to reveal his bank card PIN? I think that's unlikely. The victim's phone was at the crime scene and there were no records of any transfers. We also found the perpetrator's bank card in the closet. If the perpetrator was really after money, would they have left the bank card after forcing the male homeowner to reveal his PIN?"

"Therefore, I think we need to expand on the suspect's motive. I think it's highly likely that the other party took the jewelry to cover up their true criminal purpose."

"I personally think we should start from two aspects. The first is to investigate the male homeowner's interpersonal relationships, including his work, social relationships, family finances, and so on. The second is to investigate the female homeowner's interpersonal relationships. She had signs of being assaulted before she was murdered, and she had only been married for three months. We should investigate her romantic relationships, whether she had any ex-boyfriends or other people with whom she had emotional ties. This aspect should be the focus of our investigation."

Chen Jianguo's meaning was clear. Although the circumstances at the crime scene suggested murder for financial gain, it was highly likely that the suspect had deliberately left clues to evade police capture, or to mislead the police investigation.

Everyone nodded in agreement with Chen Jianguo's suggestions. Qin Chuan, in particular, strongly agreed with the latter two points Chen Jianguo made.

The criminal investigation team pays too much attention to detail when solving cases. Of course, this doesn't mean that details shouldn't be considered when solving cases. On the contrary, many cases are solved by starting with details. Some inconspicuous clues, such as a loose thread or even a paperclip, can become highly indicative clues that can guide the police to quickly find the suspect and solve the case.

However, in this case, the criminal investigation team focused too much on the details and overlooked some of the overall characteristics of the case. This is because frontline technical personnel, case investigators, and leaders have different perspectives, so what they see, what they discover, and the direction they take will also differ.

The information that Chen Kai and his team provided to Qin Chuan in advance actually showed that the Criminal Investigation Detachment had done a lot of work since last night. Almost no one in the Criminal Investigation Detachment had rested; they had been working on this case all night.

However, this doesn't mean that simply doing all the hard work will guarantee the desired results. For example, one question Chen Jianguo just raised is: why did the suspect choose to commit the crime during dinner time yesterday afternoon?

If the suspect was truly after money, wouldn't it be safer to get the valuables without causing death? But the suspect chose to act during dinner time, when everyone in the family is present. With so many people around, going in to rob and kill might not only result in the loss of a large amount of property, but could also lead to the suspect being killed instead.

So although some jewelry was missing from the master bedroom and it has not been further confirmed whether other financial matters were stolen, this does not mean that the case was murder for money.

In a typical crime investigation, if it's a murder for money, the perpetrator likely intended to steal first, and then the family member's unexpected appearance at a time when they weren't supposed to cause the suspect to commit the murder in a moment of desperation. In other words, the suspect only killed during the robbery under duress.

But the scene was clearly not like that.
