Teen accused of killing mom with hammer, knife on New Year's Eve

Tokyo - When investigators arrived, the woman was lying bleeding in the living room

A 16-year-old boy in Japan was arrested Saturday after he confessed to killing his mother by repeatedly striking her head with a hammer and stabbing her several times, police said.
The high school student, whose name was withheld because he is a minor, called police around 1:40 am (1640 GMT Friday) to report he had killed his mother at their home in Kurashiki, Okayama prefecture in western Japan, a local police official told AFP.
When investigators arrived, the woman was lying bleeding in the living room, local media said.
She "had suffered wounds to her head and torso and was transported to a hospital in the city. She was pronounced dead at 2:48 am, and police plan to launch a murder investigation," the police official said, without elaborating further.
Police originally arrested the boy on charges of attempted murder.
Violent crime is still relatively rare in Japan, but several high-profile cases involving young people have heightened public concern.
