I realized that Shen Tangzhi's emphasis was hinting at something to me—it might not be accurate, because Shen Tangzhi didn't know the truth, and what she had should be an intuition that she thought was worth conveying to me.

It's often the case for me myself: I have a flash of inspiration, but I can't get the point right for a while.

It's like a speeding car speeding past you, and you'll be horrified, but for a moment you won't be able to read the license plate number, and only at some point (maybe even until the truth is known) will the vague license plate number suddenly clear from the fog.

With this question, I said as if talking to myself: "Three dead people, all dead in front of the computer in the boot state?" But don't have a hard drive in your computer? No, unless there is some special reason, it is impossible for them to sit in front of a computer without a hard disk for more than three hours, which is simply not logical. Or, the hard drive that Ji Lan said really exists, but it was taken away. ”

Shen Tangzhi nodded and said: "If there is really important evidence in the hard drive, then the criminal is quite knowledgeable about electronic technology, and under the circumstances at that time, it is the best way to deal with it by taking the hard disk directly, because it is not easy to completely destroy the data in the hard drive." ”

Shen Tangzhi is right.

Whether it's flash memory, SSD, or optical disc, the safest way to destroy data is physical destruction.

It is said that the FBI can recover data written 19 times, and this is for optical media, if it is an SSD or flash drive, even if the data is overwritten 35 times by repeated reads and writes, it can still recover 4% of the data from the SSD and more than 70% of the data from the flash drive.

Shen Tangzhi continued to ask me: "So, you think it's murder?" ”

I shook my head: "No, it should still be suicide, but not ordinary suicide." ”

Shen Tangzhi's eyebrows were slightly raised: "What do you mean by this?" ”

"There are two scenarios. The first, similar to "**", is where these suicides think they are committing suicide, but are actually being booby-trapped; Second, similar to cults, they don't consider themselves suicidal, and we misinterpret their actions because they have accepted a distorted notion of death. Third, other forms of assisted suicide. ”

I paused and continued, "I think, at the very least, assisted suicide, no matter which of the above situations, the aided offender must exist. So, our first step is to find an assistant! ”

Li Yi was dumbfounded as he listened, this guy didn't seem to understand our analysis at all, and he was probably stunned by my series of various "suicides".

Shen Tangzhi only thought about it for a while, and then stretched his brows: "The direction is correct, but how can we narrow down the scope of investigation?" ”

"I found that these suicides have one thing in common, although they are all middle-aged, they are all computer savvy, and they are basically related to the electronics industry, so I also set my target for this kind of people: middle-aged IT workers who live alone." I said.

Shen Tangzhi still has doubts: "In the entire Jinguan City, there are probably no less than 100,000 employees in the IT industry, among whom there are still a lot of 'middle-aged' and 'living alone' conditions, right?" ”

"Well, what about the conditions of the living quarters?"

As I spoke, I turned on the desktop computer in the southeast corner of the office, along with the projector hanging from the ceiling.

Soon, on the white wall above the sofa where Shen Tangzhi was sitting, a complete map of Jinguan City was projected.

I sat down at my computer desk and did a bit of work, and a couple of red dots appeared on the big map, followed by a circle, and the red dots happened to be circled in it.

Shen Tangzhi immediately understood: "The red dots represent the locations of the three places of death that have been discovered now, and you want to narrow down the monitoring scope to the area where this circle is located?" ”

Given the very limited resources we have, there is no way to do it, and even if we do it in vain, we can expand the scope of surveillance according to this method when similar cases happen again, and I will continue to look for other breakthroughs.

Shen Tangzhi had no objection, she said that after returning to the police station, she would send me the addresses of eligible target persons within the scope of my circle.

Specific to monitoring, I can't handle this matter alone, the old knife is not there, and the police bureau will not send someone to cooperate with me, so I can only ask Li Yi for help.

This guy naturally didn't do it, but with the pressure of Shen Tangzhi, a big creditor, Li Yi had no choice but to accept the unequal treaty in humiliation - including him, including himself, his little brothers were all pulled by me, and as soon as it got dark, he was sent to the vicinity of the target's residence to monitor all night.

For a while, the security of several nearby streets was greatly improved, Li Yi and his little ruffians were choked enough by me, living like bats, sleepless all night, and then sleeping peacefully in their own homes during the day, all of them were lacking yang and sluggish, how could they have the spare energy to cause trouble?

Where can the little gangsters stand this, and within a few days, they scolded their mothers and complained.

Li Yi ran to Shen Tangzhi's side to complain, Shen Tangzhi waved his little hand, threw a check directly in his cousin's face, and domineeringly gave each of his subordinates 5,000 yuan of hardship fees, and said that there would be 5,000 bonuses after solving the case.

As soon as they got the money, the gangsters immediately refreshed themselves, and when it was time to go to work at night, their eyes lit up one by one, and they told me that they must catch the murderer as soon as possible.

As soon as I heard the "gang rules", I immediately couldn't help it: "When the hell did you set up a gang?" You who are not breaking the law are secretly playing by yourself, and you are so arrogant on the surface, do you really think that the police station is opened by your family? Isn't it good to live well? ”

Li Yi sighed for a long time, with a look of lovelessness: "Those bastards under my hands, Lao Tzu has been eager to use a dime for their livelihood all these years, and he also gave Brother Dao a double-sided undercover agent, don't mention how hard and tired it is, I didn't expect these white-eyed wolves to be mothers with milk!" Brother Ji, they call me big brother now, call me cousin Galeries Lafayette...... Look at ......."

Li Yi has more than 20 junior brothers, that is to say, Shen Tangzhi casually spent more than 100,000 at once, and if the case is solved later, he will have to throw out so much.

It's rich. I feel it.

Li Yi told me that Shen Tangzhi and he are distant cousins, their grandparents are brothers, and in their generation, they are actually more estranged, that is, they still met occasionally when they were children, and they no longer contact each other when they grow up.

The other Li Yi didn't continue.

I know this guy's family background, I can't say how poor he is, ordinary people, but judging from Shen Tangzhi's style, a typical rich lady, as for why Li Yi didn't say it carefully, it was people's privacy, he was not happy to say, and I was not interested in asking.

With friends, I like to make some space and feel more comfortable with each other.
