The Setagaya Family Murder Case: The Bereaved Family’s Wish and the “Wall of Law” that Prevents the Truth from Being Revealed

Setagaya-ku, Tokyo Occurred on December 30, ’00

A quiet residential area in Setagaya Ward, Tokyo. It has been 21 years since someone murdered Mikio Miyazawa, then 44, and four other members of his family here.

It’s a good idea to have a good idea of what’s going on in your life.
It is believed to be one of many interviews.

In the past, the police have deployed a total of more than 280,000 investigators. So far, the police have deployed a total of more than 280,000 investigators and have collected and examined a total of 59 million fingerprints and 1.3 million pieces of DNA information. A source close to the investigation reveals the inner workings of the current investigation.

In addition to improving the accuracy of DNA analysis, we are putting more effort into interviewing and collecting DNA. We are conducting interviews and asking those who cooperate to provide us with their genetic information so that we can match it to the crime scene one by one.

As time has passed since the incident, the number of investigators is limited, but the steady investigation is still going on. However, there is a “legal barrier” standing in the way.

In the U.S., there have been more than two dozen cases in which highly reproducible portraits have been created from genetic information collected, leading to the arrest of criminals. However, in Japan, genetic information is considered to be the ultimate personal information and is not used in DNA investigations. Japan should adopt the use of genetic information,” said Takeshi Tsuchida, former chief of the Seijo Police Station of the Tokyo Metropolitan Police Department.

On December 18, 2009, a meeting of the “Sora no Kai” was held near the crime scene, and Setsuko, 90, mother of Mikio, appealed for the promotion of legislation to realize a wide range of DNA investigation.

Unsolved cases with no statute of limitations. The struggle between the police and the bereaved families continues.
