I finally confirmed that Li Yi, this kid, did have some tricks pinched, I thought it was Ji Lan before, and when Shen Tangzhi appeared, the answer was 100% correct.

Li Yi helped me light the fire, I took a deep breath, and then said: "If I remember correctly, your cousin doesn't smoke, I advise you to be more restrained in front of creditors." ”

Li Yizheng's hand stopped to light, and under Shen Tangzhi's gaze, he smiled and took off the cigarette in his mouth.

And I just pretended, without waiting for Shen Tangzhi to stare at me, I snuffed out the cigarette in the ashtray.

"I'm a little curious, what did you get into your cousin's hands?" I asked Li Yi.

Li Yi glanced at Shen Tang again, and the latter smiled at me: "It's nothing, I just borrowed some money from him." ”

"How much?"

Li Yi was a little embarrassed: "One hundred, one million." ”

My eyebrows jumped and I looked at Shen Tangzhi: "You don't wear gold or silver, but you are still a rich woman?" It's so hidden that it's completely unrecognizable. In other words, if you borrow a million, you won't be afraid that the meat bun will hit the dog and never go back? ”

For my ridicule, Shen Tang laughed at it.

Li Yi said aggrievedly on the side: "Brother Ji, what you are talking about, am I Li Yi that kind of person?" ”

"Speaking of which, didn't you kid go to send Ji Lan? I'm counting on you to get me some clues. ”

Li Yi said with a bitter face: "People are only willing to let me send it to the bus station, and then take a taxi by myself." ”

"Rotten wood cannot be carved...... Your kid's taste has always been inseparable from the big gold chain and flower shirt, these hands will also deal with the little sister on the street, serious women don't eat your set, please watch more romance dramas, okay? "Send Li Yi to the side to rest, I clasped my fingers together, put it on the table, and said to Shen Tang, "Anyway, since Section Chief Shen is both bold and golden, it will be easy to handle, you say, how much should I charge you for this case?" ”

"I want the lion to open his mouth, don't dream." Shen Tangzhi clasped his hands in front of his chest, and his face seemed to be smiling, "In this way, depending on the complexity of the case, I will give you 5 to 100,000 yuan, and in addition, if you write the case record into a case file and hand it over to me afterwards, I will add an additional 30,000 yuan." ”

I suddenly remembered that I was forced to write a file to her in the case of "Chain of Crimes": "What, are you still addicted?" ”

Shen Tangzhi raised his eyebrows and only issued a series of tone auxiliaries to me: "Uh-huh." ”

The reality is that the money in my pocket was almost at the bottom a month ago, because I had been out of business for months, and I couldn't help but be on my usual extravagance with the little money from the grocery store, and it was like drinking the northwest wind for more than a month.

Therefore, I asked for an advance of 20,000 yuan.

After Shen Tangzhi asked me the truth that I was about to uncover the pot, he couldn't help but smile and agreed.

Then there is nothing to hesitate, I decisively folded my waist for five buckets of rice, and it is difficult to drink the northwest wind!

It's not charity, we also have to pay our own labor, right?

Real money was credited to my account, and my enthusiasm for work suddenly increased.

I asked Li Yi and Shen Tangzhi to sit down for a while, and I began to study the three bags of case files on the desk again - the old knife is not here, and I can't go to Cheng Cheng for help without a breakthrough, it just so happens that Shen Tangzhi, an internal member of the police bureau, is present, so I naturally have to be good at using it.

The police characterized the three deaths as suicides, mainly because a series of on-site investigations, including subsequent autopsies, could not directly prove homicide.

In the process of solving any case, the most important elements are four elements:

One, the murderer.

Second, motivation.

Three, the technique.

Fourth, evidence.

The absence of any one or more of the four elements will be a huge challenge for the conviction of the offender, and it is impossible for the defense lawyer to miss any opportunity to exonerate his own representative in court.

And these four elements are not independent of each other, but are stuck together like a spider's web.

In the field of criminal investigation cases, it can be explained that every incident has a cause that leads to its occurrence.

It is impossible for a person (even if he is mentally ill) to kill (or commit suicide) for no reason.

To put it simply, if a person wants to kill another person (or commit suicide), he must first have the idea of killing, followed by the idea of a specific method of killing, and finally the actual implementation of the plan, and in the whole process, there will be more or less some evidence left, which is necessary to support the correctness of the detective reasoning.

As an additional mention, since there is no need for a motive to kill due to accidental death, many criminals will disguise the scene of the murder as an accidental death in order to get away with it or confuse their eyes.

Specific to me, I am not a police officer or a detective in the general sense, the four elements of solving the case are not an iron law for me, a spirit detective, in fact, it is not an iron law, I have experienced many strange events, there are not a few events that completely break this law, but every time I am in the process of exploring the truth, the four elements of solving the case are also very helpful, and it is also an extremely important tool in my hands.

Therefore, in the case in front of me, I also used the four elements of solving the case to separate and analyze the puzzle.

First of all, I do not agree with the official identification of the suicide, I firmly believe that the murderer is someone else, but he is still hiding behind the scenes, and has not yet revealed his tail.

Secondly, in terms of motivation, I temporarily think that it is the hard drive, although this is a hard drive that only exists in Ji Lan's description, and no one can confirm whether it really exists except Ji Lan - but this hard drive represents the motive of the whole incident in my reasoning.

Moreover, there is no reasonable explanation for the strange deaths of the three deceased. But in other words, if we can crack the modus operandi, we may be able to lift the veil that veils the truth.

Finally, there is the evidence. This is the most troublesome point for me, and my assumptions about "murderer", "motive", and "modus operandi" are not supported by any evidence at all.

After a while, the files and documents were all over my office desktop, so that Shen Tangzhi had to take her teacup and move with Li Yi to the northeast side of the room, where there was a set of sectional sofas and coffee tables.

When I was in a painful thought, these two guys turned on the tea party mode over there, and my strong protest was in vain under Shen Tangzhi's obscenity - they are now my clients and financiers, and after several times, I can only accept the cruel reality.

After thinking about it for a long time, I first thought of an entry point: fingerprints on the scene.

All of these suicides have lived alone for many years, but fortunately, the police still collected some footprints and fingerprints in their houses that are not their own, but although these people live alone, they also have jobs, and people are social animals, how can they not have any social activities?

According to the confessions of nearby residents, no one witnessed the suspicious strangers appearing nearby at the time of the crime, and the footprints and fingerprints collected by the police at the scene were basically those of these neighbors.

A small number of unidentified fingerprints were entered into the police fingerprint database for search, but there was no result, which confirmed that these fingerprints were not owned by habitual offenders with criminal records.

In addition, the police have also matched the owner's fingerprints collected from various suicide scenes, but have not found any fingerprints that have ever appeared in the two cases.

I looked up from the pile of documents and asked Shen Tangzhi, "Have you been to the scene?" Are there any particularly clean places? ”

Shen Tangzhi is a forensic doctor, so she naturally understands what I mean: "I haven't been to the scene yet." However, according to the on-site investigation records, no traces of deliberate destruction of the scene were found, including doorknobs, various cabinet doorknobs in the room, tabletops, cups and other places that are easy to leave fingerprints, all of which are normal and have not been erased. In addition, I emphasize again, all the corpses, there is no trace of moving. ”
