TOKYO - A Japanese schoolgirl has confessed to decapitating a classmate, police said yesterday, as she reportedly told investigators that she "wanted to dissect" someone.
The 16-year-old teenager, whose name was not released as she is a minor, was arrested on Sunday on suspicion of murdering her 15-year-old female classmate, after police discovered the dismembered body on a bed in the suspect's home.
The accused has admitted that she strangled the victim before severing her head and left hand, "using tools... and something like a cord", a police investigator said.
"The victim was found decapitated, with her left wrist chopped off," the investigator said, adding that the murder likely took place on Saturday evening.
The two girls attended the same high school in Sasebo, a city in south-western Japan, the police said.
The police discovered tools, including hammers and a saw, at the suspect's apartment, the top-selling Yomiuri newspaper reported.
The girl lived on her own after her mother died of cancer last year, but her father and stepmother live in the same city, reports said.
"I wanted to kill someone. I bought tools by myself," the Yomiuri quoted the girl as telling police.
The popular Sports Nippon newspaper said the alleged killer told police she "wanted to dissect" a body, adding that the victim's belly was cut open.
The police official declined to confirm the reports, saying "we are investigating her motive for the crime, and we're not going to disclose other information".
Sasebo had already made headlines in 2004 when a primary school girl stabbed her classmate to death.
