Lin Lei was able to know so much, mainly because the police later shared the case with the ICPO and some detectives and senior police officers at the level of detectives in the United States and Europe, hoping that they could help solve the case. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

So far, after everyone has read the facts of the case, no one has any thoughts about this case, and naturally no one has come to solve the case.

If there is, then Lin Lei is the first.

This case is too weird, and the clues are insufficient, people who are not high enough dare not come, and people who are high enough are unwilling to come to this muddy water, so as not to ruin their reputation.

After Lin Lei gave a general account of the first case, Qiao Yan was the first to ask a question.

"BOSS, the body of the deceased Kojima Katsu must have been autopsied, the time of death should be certain, right?

As a forensic doctor, it is natural to ask such a question, Lin Lei glanced at Qiao Yan, nodded slowly, and said, "Well, the time of death and the cause of death can be roughly determined." ”

"Probably?" Qiao Yan frowned, a puzzled look on her face.

With the degree of scientific and technological development at that time, and in a country with very advanced criminal investigation technology such as Yuben, the error in determining the time of death would never be more than 30 minutes.

Provided, of course, that it was discovered early.

And Kojima Katsu's body was found very early, and it was not a corpse that had been soaked in water for many days, nor was it a corpse buried in the soil. The time period of his death was just about ten hours after the rest of the work and the morning when Ichiro Takenkoichiro found the body.

In terms of the "freshness" of the crime scene, the error in judging the time of death must be very small.

However, Lin Lei said the word "probably", which made Qiao Yan feel very strange.

Lin Lei shook his head helplessly and began to explain the problem.

It turns out that the two most basic means of judging the time of death of the deceased are the stiffness of the corpse and the digestion of the stomach contents.

First of all, the mortis situation is not very helpful in this case, because of the presence of the fireplace.

The fireplace can change the ambient temperature, and the temperature has an extremely important influence on the process of the formation of mortis.

Katsu Kojima is a fat man, and he is usually more resistant to cold. In the office, the fireplace is always burning because I have to take care of other colleagues.

However, no one knows whether the fireplace continued to burn after the colleagues left.

From the later inspection of the combustible ash in the fireplace, it is clear that the fireplace must have been burning for some time, but definitely not all night.

This is tricky because no one knows when Katsu Kojima lit the fireplace, and no one knows when the fireplace went out.

In short, the police could not determine whether the indoor temperature was high or low after Katsu Kojima's death.

If the fireplace is burning when Katsu Kojima hangs himself, the problem is very tricky.

This is because the indoor temperature should be relatively high before the fireplace burns out, and after the fireplace burns out, the indoor temperature drops dramatically.

Temperature has a very large impact on the formation of mortis, and the situation at the scene makes it impossible for the police to judge the specific time of death from the zombie.

The second is to determine the time of death by the degree of digestion of stomach contents.

However, the road is not smooth.

Police were able to determine that Katsu Kojima died about five hours after the last meal.

The crux of the matter is that Katsu Kojima, the "last meal", was alone on the night shift, and no one knew when he had dinner.

The police can only speculate according to common sense that 18 to 20 o'clock is the meal time, so the time of death of Katsu Kojima is between 23 o'clock in the morning and 2 o'clock in the morning.

This time frame is too large, and it is also derived from "speculating on the time of eating......

The time of death is crucial information for a homicide, and it must be "stuck" accurately, otherwise it will be a thousand miles wrong.

The Hokkaido police used various technical means to help, and even brought in an anatomical expert from the University of Tokyo to assist, and finally confirmed that the time of death was roughly between 0:00 and 2:00, which could not be more precise......

When Lin Lei said this, Lu Yun suddenly blinked his eyes and asked thoughtfully: "Lin Lei, did it snowstorm on the night of the crime? What time did it start? What time did it stop?"

Lin Lei glanced at Lu Yun appreciatively, her question was very critical!

Lin Lei took out a piece of chewing gum, put it in his mouth and chewed it, and said in a deep voice as he chewed: "The blizzard that day started at about 23 o'clock the night before and lasted until 4 o'clock in the morning. After 4 o'clock, the snow gradually decreased, and by morning it almost stopped. ”

"BLIZZARD?SECRET ROOM?XING SUFFOCATION?" LU YUN SAID THREE WORDS IN ONE BREATH, AND THE MEANING BEHIND EACH WORD WAS WORTH "PLAYING".

"The secret room is not yet the secret room, the focus of this case is not the secret room. Lin Lei smiled and glanced at Lu Yun meaningfully.

Lu Yun nodded slightly, and did not answer.

There is more than one key to the courtyard gate and the door of the house, and in addition to Kojima Katsu, there are also these keys.

If......

Uh-

Lu Yun's brows furrowed even tighter, she rubbed her temples and didn't continue to think about it.

It is not impossible for the police to kill the police, but Lu Yun, who is also a policeman, is unwilling to think deeply about this line.

Anyway, the investigation has not yet begun, and there is no need to limit the scope of the murderer in advance.

"If XING is suffocated, the lower body of the deceased Kojima Katsu, has it been checked...... That ......" Qiao Yan's face turned red, although she was a little embarrassed in front of the man, she couldn't help but ask this "embarrassing" but crucial question.

Of course, Lin Lei knew which "that" was, he nodded, and said in a deep voice: "Yes." ”

However, soon Lin Lei changed his words, frowned and said: "The computer playback record that day shows that Kojima Katsu watched a 'small movie', and there are tissues in the paper basket. This illustrates...... Hmm, you all get it, right?"

Lin Lei didn't continue, but Qiao Yan and Lu Yun definitely understood what Lin Lei meant.

Since Katsu Kojima has watched "small movies" and has "that", it is normal for him to have "that" in his lower body.

Maybe it's left over from "after that", maybe it's suffocated by XING, who knows?

This is very troublesome, and even the police can't even determine whether Katsu Kojima died by accident or not.

If it is a homicide, there seems to be no more evidence to support it.

"What happened later? How did the case go after that? After all, it was a case from five years ago. Lu Yun thought for a long time and asked.

Lin Lei's eyes flashed, and he quickly squinted his eyes slightly, and said lightly: "Although the Hokkaido police mobilized a large number of police to investigate, no clues were found, and the case has been shelved without any progress. Until—"

Lu Yun and Qiao Yan's hearts suddenly hung up, and they asked in unison, "Until what?!"

Lin Lei's eyes deepened, and he replied slowly: "Until a year later, Koichiro Takekoichiro was found dead in the duty room by his colleagues!"

"Koichiro Take, the first discoverer at the scene of the crime?"

"Yes. ”

"How did you die?"

Lin Lei was silent, and after a long time, he said word by word: "XING is suffocating." Exactly the same way to die!"
