I pulled up the case file of this accident and put it on a white screen on the wall of the office of the Crime Unit.

"Rose, bathing center, marketing director. This case is indeed somewhat similar to the serial murders we are experiencing now. Lin Zifan said seriously.

"This is a case that happened five years ago, and it wasn't that long ago. The criminal investigation technology is also very advanced, not much different from what we have now. The important thing is that they didn't find any suspicious points at that time, so are we sure we want to overturn the case? Jiang Tingbai rubbed his head and felt a little embarrassed.

Overturning the case is the last thing we like to do as a criminal policeman.

Because this means that the previous cases are doubtful cases, unsolved cases, and cases with wrong conclusions.

This completely negates the criminal police who were responsible for the investigation and investigation of the case at that time, negates all the results of their investigation day and night, and at the same time, it also loses our authority as criminal police.

I shook my head slowly and explained seriously: "It's not that there are doubts, there are doubts, but it's not enough to change the nature of the case." We don't have to doubt the professionalism of the criminal police who solved this case at that time, we are also criminal police, we know that we need to pay attention to evidence in handling cases, and the chain of evidence is closed, and there is no doubt about the crime. ”

"There is no doubt about the guilt......" Xue Hang muttered.

"The file shows that the time of the crime was half past nine in the evening and the location was on a suburban road in Ningzhou City.

It was the birthday of the deceased Li Xuezhen, and she held a birthday party at home, inviting her friends and better colleagues.

The birthday party was at Li Xuezhen's home, and there were twelve people attending the birthday party, all of whom were very good friends with Li Xuezhen, in other words, they were all Li Xuezhen's most trusted people.

At the birthday party, everyone did not drink alcohol, and the autopsy results also showed that no alcohol, hallucinogens, toxic substances and other ingredients were found in Li Xuezhen's body. According to the police investigation, everyone who attended the birthday party that day could prove that Li Xuezhen did not drink alcohol, and everyone ate what she ate.

In addition, everyone proved that Li Xuezhen received a phone call at the birthday party, and the call was from a colleague from Li Xuezhen's company, saying that there was an important impromptu meeting that Li Xuezhen needed to attend.

So Li Xuezhen left the birthday party early, and when she left, she said that she would come back in an hour, so that everyone should not leave, and wait for her to come back to continue.

Then Li Xuezhen drove away alone, and there was a car accident on the road.

At that time, the company had an important project, and Li Xuezhen was indeed busy for a long time, and there was indeed a lack of sleep, which also provided key evidence for the conclusion of fatigue driving.

The person who called Li Xuezhen was the deputy general manager of the company, named Pu Licheng, and after police investigation, he and the deceased Li Xuezhen had a competitive relationship in the workplace.

They both held shares in the company, and a month after Li Xuezhen's death, Pu Licheng bought all of Li Xuezhen's shares.

However, this is all after the case is closed, and his acquisition of shares is also a reasonable and legal business operation.

Pu Licheng and Li Xuezhen have a competitive relationship, and colleagues in the company all say that the two of them are at odds with each other and secretly compete with each other.

But Li Xuezhen's home, as well as the place where she had the car accident, are all forty kilometers away from Pu Licheng's location, and Pu Licheng has an alibi.

Although Pu Licheng was suspicious, he did not have the time to commit the crime, nor did he have the means to commit the crime.

After investigation, the reason why Pu Licheng called Li Xuezhen that night was because a partner of the company had some questions about the contract and was going to hold an impromptu meeting to discuss it, so Li Xuezhen hurriedly drove away.

And this partner is the company where Song Simeng works, but at that time, Song Simeng was just an ordinary employee who had just come to the marketing department, not a marketing director, so this matter had nothing to do with her.

As for the complete bouquet of roses, it becomes a permanent doubt. It's just this suspicion, and it doesn't mean anything.

At least no one can prove whether there was this bouquet of roses in the car when Li Xuezhen left.

Even if everyone's habitual thinking will think that such a serious car accident will definitely damage the roses, but no one can be sure that the roses will be damaged in this kind of sudden event.

Even though it was once thought to be a homicide disguised as an accidental car accident, Rose was placed in the car by the killer after the accident.

But the police conducted three on-site investigations and found no firm evidence of the existence of this so-called 'murderer'.

Unless, it's a perfect crime. ”

I would like to tell you about the accident that happened five years ago, and the file contains all the clues of the case, including the on-site investigation records, investigation and visit records, incident records, and the process of solving the case. Everything is very professional, that is, it is to be done by our serious crime team, which is nothing more than this result.

"It's just that the time of the case was five years ago. And we are five years from now, and from the perspective of future generations, combined with the cases we are currently investigating, there is a big difference. Li Meng said in a deep voice.

"Yes, there are a lot of things that have to do with this case that happened five years ago and the case that we're investigating five years later. The first is the presence of roses, the second is the position of marketing director, and finally the company of the deceased. The deceased's company was a chain of bathing centers, which coincided with our previous judgment of "puppies, ducks". The most important thing is that the deceased's company has a cooperative relationship with Song Simeng's company. I nodded, and then Li Meng's words were seriously analyzed.

"Is it really a perfect crime? Was it a perfect crime at least five years ago? Lin Zifan frowned, revealing a meaningful expression.

"Whether it's a perfect crime or not, as long as it's done by a person, it will definitely leave a clue. I think this bouquet of roses is the key piece of evidence. Jiang Tingbai nested on the office chair, crossed his hands behind his head, and said a little lazily.

"It seems that the murderer is still an obsessive-compulsive patient, if this bouquet of roses was really put in by the murderer after the car accident. Then it is also in line with the situation of this serial homicide case we are investigating, which is a professional habit that cannot be changed. Xue Hang looked at the dossier on the white screen seriously and said coldly.

"Moreover, the murderer thought that his methods were not discovered by the police five years ago, which gave him great confidence, so today, five years later, the murderer killed two people in a row, left roses at the scene of the crime, and took the initiative to call the police." Li Meng said quietly.
