A 13-year-old girl who allegedly stabbed her mother to death at their home in Shizuoka Prefecture, central Japan, has reportedly told police she quarreled with her mother over her use of a smartphone.
Police responding to call from a home in Makinohara City shortly before midnight on Monday found the mother, in her 40s, lying bleeding in a second-floor bedroom. She was pronounced dead at a hospital.
The daughter was at the house when police arrived. During questioning, she admitted to stabbing her mother.
Police notified a child consultation center about the girl, who had a smartphone when they found her.
The mother had multiple wounds to her neck, and a blood-stained knife was found in the home.
Police believe the girl may have attacked her mother while she was asleep.
