Seeing this, Lin Lei couldn't help but gasp.

If the footprints are isolated evidence, then the footprints cannot be used as evidence for conviction.

In terms of probative power, footprints are not unique, and they cannot be compared with fingerprints and DNA.

Fingerprints and DNA are the ultimate physical evidence, while footprints are clearly not.

But this case is different from the others.

The place of the crime is a relatively closed apartment building.

After the incident, the police investigated the scene in detail, whether it was inside or outside the house, or even around the scene of the crime, all the evidence showed that no outsiders had been to this apartment building at the time of the crime.

In other words, the murderer could only be one of the five occupants in the apartment - or two or three, and it is almost impossible for an outsider to trespass anyway.

If someone's footprints appear at the scene of the crime in a relatively confined space, then his suspicion is infinite.

The reason why footprints can't be definitive evidence like fingerprints and DNA is mainly because there are so many people in the world, and there are not too many people who wear the same style and the same shoe size, so it's so unusual?

However, the scope of the crowd is limited, and among the five people, someone's shoe prints appeared at the scene of the crime, which is indefensible.

In addition, through investigation, the police determined that Zhao Yi belonged to the category of "idle", that is, there was no so-called formal job, and he also deceived his parents, obviously of inferior character.

This is not to say that people with poor character are necessarily criminals, but Zhao Yi left a very poor image to the police and belonged to "unstable elements".

If Zhao Yi is an international student with excellent character and learning, then the police will be more cautious if they identify him as a murderer.

At present, the police did not say that Zhao Yi must be the murderer, but only arrested him as the first suspect.

Whether the suspect is prosecuted or not has nothing to do with the police.

In any country, this is the work of a "prosecutor".

After the case materials were transferred to the Tokyo District Prosecutor's Office, the prosecutor decided to prosecute Zhao Yi after the case was unable to say that the evidence in the case was particularly sufficient, but it could not be said that there was no evidence.

Since the main evidence is shoe prints, no one knows how the judge will hear and pronounce the verdict.

Typically, there are several possibilities for such a case.

First, the suspect is convicted on the basis of the available evidence alone.

Second, the evidence was insufficient, and the suspect was released in court.

Third, although the evidence is insufficient, it cannot be ruled out that the suspect was convicted and the charges and sentences were appropriately reduced.

At present, the first possibility can be basically ruled out, because the evidence of "shoe prints" in this case cannot support the complete crime.

The second possibility is a high probability event, and if it is a citizen, the judge will be very careful in the trial.

The key is that Zhao Yi is not a Japanese national, so the third possibility has skyrocketed.

For example, if the crime of homicide should be sentenced to 20 years in prison, it is reasonable to sentence Zhao Yi to 10 years.

You can't say it's reasonable?

So can you explain why shoe prints appeared at the scene of the crime?

And the police can already conclude that the murderers are several people in the apartment.

It is also possible to convict suspects through the chain of evidence, but the "probative force" is slightly worse, and the general sentence is slightly shorter.

Regarding the two aspects of conviction in criminal cases, "ironclad evidence" and "chain of evidence" do not need to be repeated, everyone understands them.

For this case, in a relatively confined space and limited scope of suspects, the "shoe prints" that appeared at the scene are a very critical link in the evidence chain, which is enough to prove a lot of things.

Of course, this is not conclusive evidence, but Zhao Yi himself can't explain the shoe prints.

Although the evidence of shoe prints in this case is not sufficient, the issue of "shoe prints" cannot be ignored under the circumstance of limiting the scope.

In fact, there are many ready-made cases where the verdict is pronounced in this way.

For example, in many homicide cases, because the evidence is not conclusive evidence, but it cannot be completely ruled out, the final sentence of the suspect is life imprisonment or more than 10 years imprisonment.

In short, the judicial environment is much better than before, and as long as it is not ironclad, the suspect will never be sentenced to death.

Even so, Zhao Yi is facing a sentence of more than ten years, which can be regarded as a heavy sentence.

That's the general case.

The most critical part of this case is the shoe prints that appeared at the scene of the crime.

From beginning to end, from beginning to end, the Japanese police and the local prosecutor's department did not say that Zhao Yi must be the murderer, but his suspicion is very large, and judging from various circumstances, Zhao Yi is far more likely to kill than others.

After reading the file, everyone did not speak, and each thought about the various possibilities of the case.

After a long time, Qiao Yan spoke: "BOSS, I think there is a drama in this case." It is too far-fetched for the police to rely on the evidence of shoe prints to prove that Zhao Yi is the murderer. As long as we can find the shoe prints that do not necessarily belong to Zhao Yi, we can clear his suspicions. ”

Qiao Yan is right.

There were only a few people at the scene of the crime, and now because the scope of suspects is limited, it is said that the party decided to arrest Zhao Yi. If this circumstance is not true, then shoe prints do not prove anything.

It seems a bit of a twist, but to explain it in one sentence, that is-

It is precisely because the murderer is limited to five people in the apartment that Zhao Yi's shoe prints can become a key piece of evidence.

Lin Lei nodded, and said in a deep voice: "Let's go to the scene first to take a look, why did the local police limit the murderer to the people in the apartment?"

After a pause, Lin Lei continued: "If there is a possibility that a foreign criminal committed the crime, then the shoe prints cannot prove anything at all. ”

Lu Yun bowed slightly and agreed: "Well, the specific situation still has to go to the scene to take a look." ”

Detective Fujimoto straightened his throat and said with a smiling face: "Detective Lin is right, I think there must be something strange about this case, and we must carefully investigate the scene of the crime." ”

Without further ado, Lin Lei quickly led everyone to the scene of the crime - the apartment building in Luqi Town.

When he arrived at the scene, Lin Lei immediately understood why the local police thought that this case could not be committed by a foreign murderer!

Because the apartment is a detached yard, there are all monitors in the southeast, northwest and four directions.

In this way, because the surveillance cannot lie, and the surveillance just covers all the entrances and exits of the crime scene, the police can conclude that the murderer is not an outsider through the surveillance.

Lin Lei walked around the apartment again, and finally came to a conclusion: it is absolutely impossible for anyone to avoid surveillance to enter and exit the apartment.
