Japan Still Cannot Identify Family's Killer 25 Years On, Who Ate and Napped at the Scene
In Japan, every member of a household was killed inside their home. The killer has still not been found, even though 25 years have passed and thousands of pieces of evidence were collected.

A particularly chilling murder case in Japan has remained unsolved for a quarter of a century. An unknown person broke into a family's home and killed everyone who lived there.
The crime stands out not only for the number of victims but also for the offender's behaviour. After the killings, he ate in the house, dozed off and used the toilet. This means he stayed at the scene for an extended period and left several traces behind.
Plenty of evidence, no answers
Investigators have thousands of pieces of evidence at their disposal. Even so, after 25 years none of it has helped establish who the perpetrator is, and the case remains unresolved.
It is this contrast that raises the question of why such a wide body of evidence has so far produced no result. The source material stresses that the search for the killer continues and that his identity is still unknown.
Further details about the investigation, the victims and the evidence are not set out in the original short publication.
