JAKARTA - What do the Japanese Police have in their investigation of the Setagaya Family Murder? There are many. The police already have more than 16,000 pieces of information from the public. But who did it, has not been caught yet.

One family was murdered viciously at Setagaya Ward Tokyo in 2000. This means that his age is more than 280,000 officers and is still involved in the investigation that is still being carried out to this day.

Mikio Miyazawa (44 years old); wife Yasuko (41 years); his daughter Niina (8 years old) and his son Rei (6 years old) were found dead on the morning of December 31, 2000. Rei was strangled to death. The other three were stabbed to death.

Various analyzes related to this case continue to emerge. But the most widely accepted version, he entered Miyazawa's house through a small window in the second-floor bathroom.

The perpetrator's first target was Rei's bedroom which was located right next to the bathroom. The perpetrator found Miyazawa's youngest child sleeping and strangled him. Rei was the only victim to be killed by strangulation and the only one who did not have stab wounds or bloodstains on his body. It was in this bedroom that the police found the most footprints.

Reporting from Japan Today, Saturday, December 11, the police concluded that the clothes, including sweaters, and knives left by the perpetrators at the scene had been purchased in Kanagawa Prefecture. Three types of powdered fluorescent dye were found in shoes and bags left at the scene.

In the pocket of the sweater, which had only been sold two months before the murder, were found traces of a fallen bird, a Japanese zelkova tree, and a willow leaf.

DNA analysis has revealed that traces of blood (type A) found at the scene not belonging to the family suggest that the killer had a mother of European ancestry, possibly from a country near the Mediterranean or the Adriatic Sea.

Y-chromosome analysis has revealed that the killer's father is of Asian descent, with DNA appearing in 1 in 4 or 5 Koreans, 1 in 10 Chinese, and 1 in 13 Japanese. He is believed to be around 170 cm tall and thin.
