A 17-year-old boy was arrested on Wednesday after he allegedly stabbed his 14-year-old sister to death at their home in Kurashiki, Okayama Prefecture.
According to police, emergency services personnel found the girl bleeding on the floor at her home after responding to a call at around 3:30 p.m. The girl's brother confessed to having stabbed her. The girl died a short time later in hospital and her brother was charged with murder. The boy, who cannot be named because he is a minor, was quoted by police as saying: "I did it because she was always making fun of me."
Police said the boy told them he attacked his sister with a kitchen knife while she was in the bathroom. The siblings' parents were both at work when the attack took place.
In a statement, the principal of the girl's junior high school said that she had attended school that day until 3 p.m. "She was a quiet and hardworking girl. I never received any reports of trouble at home," he said.
A neighbor said, "I'd never heard any rumors that the kids didn't get on. I thought they were a normal family."© Compiled from news reports
