Man arrested over murder of Hiroshima woman in 2001

Unlike Hollywood there is no master database with everyone's DNA, for a match the DNA must be in the system somehow. Perhaps the suspects data was not in the system until only recently. Many cold cases in America for example aren't solved until decades later because the suspects DNA was never in the system, not until they commit some other crime or a relatives dna shows a close match is when someone is caught. Other could be the technology to capture in more detail did not exist until later, there are plenty of plausible reasons why it took so long, real life police work is not a 60minute drama.

If the man has no memory of doing this, it is unlikely that he committed this crime.

More than likely he did do this. You may forget certain things as you age, like what you had for dinner last Tuesday or what you wore to work on Feb 6, 2001, but committing a murder is probably something you would remember. If he says he didn't do it I would be more skeptical, but saying he doesn't recall whether he killed someone or not is ridiculous.

May she “Rest in Peace”. -

- “DNA in bloodstains at the crime scene, matched Takemori's, They said he may have become acquainted with her when he did some landscaping work at her house just before her murder.

Finally, ‘justice’ for her and some solace for her family:

Yet, 20 years have passed and *still?*:

*- “Police are [still?] investigating the connection between Takemori and the victim.*[?]

Obviously, Japanese police now need him behind bars to ‘help’ him to ‘recall’ the events.

*- “Police said Takemori has denied the charge and quoted him as saying he has no recollection of the incident.“ -*

“Almost 20 years have elapsed since the crime, causing the bereaved family to wait for justice to be served.”

Almost 20 years?

According to police, Kozo Takemori is accused of killing the woman on Feb 6, 2001, 

Its October 2021. Its well over 20 years ago. Almost 21 years ago.

Takemori was arrested on Monday morning. DNA in bloodstains at the crime scene, which were not the victim's, matched Takemori's DNA, police said. A blood-stained knife, which was the murder weapon, was left at the scene.

Did they keep blood evidence for 20 years, and if they had blood evidence, did they not think about testing it before? Something does not add up here.

If the man has no memory of doing this, it is unlikely that he committed this crime.

In a largely homogenous society such as Japan , many people in a locality would have similar DNA , and after 20 years one person's DNA looks much like anyone else's.

Now, if they have found his fingerprints on the murder weapon, that would be enough for a conviction.
