The Kofu District Court has sentenced a 19-year-old man to between 10 and 15 years in prison for killing his grandparents in the town of Fujikawaguchiko, Yamanashi Prefecture in September 2015.
The grandson, who cannot be named because he is a minor, was found guilty of killing his grandfather Masuo Mishiro, 83, and his grandmother Setsuko, 81, by stabbing them with a kitchen knife at their residence, Fuji TV reported. Police said their bodies were in separate rooms on the second floor of their home. They had multiple stab wounds to their bodies.
The court heard that the grandson planned the crime in advance by wearing a mask for disguise and preparing a change of clothes following the act. Furthermore, his motivation to inherit his grandparents' assets was ruled as “shortsighted and selfish,” the presiding judge ruled.© Japan Today
