Last year, a 36-year-old office worker in Oita City was arrested on suspicion of murder-robbery for killing two parents and robbing cash at a house in Usa City, Oita Prefecture.

It seems that he had no acquaintance with his parents, and police are investigating the details of the case.

In February of last year, Takako Yamana and her eldest son Hiroyuki (51 at the time) who lived in this house in Ajimumachi, Usa City died after being stabbed in the neck with a kitchen knife.

As a result of the police conducting an investigation by listening to the vicinity of the scene and analyzing the image of the crime prevention camera, Shoichi Sato (36), an office worker in Midorigaoka, Oita City, killed two people and cashed about 50,000 yen. He was found to have robbed him and was arrested on suspicion of murder-robbery.



According to the investigation so far, it seems that Sato had no acquaintance with Mr. Yamana's parent and child, and the police are investigating the details of the case.



Police have not disclosed their approval or disapproval as it interferes with the investigation.
