The 16-year-old Japanese school girl accused of beheading her friend allegedly told police she invited Aiwa Matsuo, 15, to her apartment intending to kill her—because, according to police, she wanted to dissect someone and had been practicing on cats, the Japan Times reports. After allegedly killing Matsuo in her Sasebo apartment Saturday night, the suspect allegedly cut off the victim's left hand and head, and now police say the victim’s belly was also cut open. The suspect told police she bought tools, including hammers and a saw, and "wanted to kill someone," the Guardian reports. The tools were found near Matsuo's body.
Police are continuing their investigation and say so far there is no evidence of a grudge between the girls, who’d been friends since middle school; in fact, the suspect says they went shopping together before the murder. This isn't the suspect's first brush with the gruesome: Sky News reports she previously got in trouble for putting bleach in food belonging to two of her classmates. (Also this month, a New York landlord allegedly decapitated her tenant—over unpaid rent.)
