About a year ago, the body of the female victim was found in some mountains near Hitoyoshi:
“The Kumamoto Prefectural Police have set up a team to look into the case, suspecting it is that of Mayuko Arakawa, 17, who was reportedly killed and whose body was abandoned in the mountains, they said Sunday.”
According to this article, the murderer was given a sentence of 18 years for the crime:
“Akaishi received an 18-year prison sentence for murdering a third-year high school [student].”
Personally, I’m not in favor of the death penalty but 18 years strikes me as light punishment for the murder of a young person with a lifetime ahead of her.
