A 17-year-old boy who was arrested in December for murdering his grandparents in Kimitsu, Chiba Prefecture, will undergo a three-month psychiatric examination, the Chiba District Public Prosecutors Office said.
According to people familiar with the matter, the boy has admitted to the charge but has given various motives during questioning, Fuji TV reported. The examination began on Tuesday.
The boy, who lived with his mother, turned himself at a police station on Dec 26 and said that he had killed his grandfather, 67, and grandmother, 64, at their house three days earlier, at around 6 a.m. while they slept.
Police quoted the boy as saying he was stressed out by problems at school and initially wanted to kill a passerby. Then he told police it would be easier to kill his grandparents because he often visited them alone and had a key to their house. He also said that he had no particular problem with his grandparents.
The boy said he used a knife, hammer and pick-ax to kill his grandparents.© Japan Today
