The 16-year-old schoolgirl in Sasebo, Nagasaki Prefecture, who has reportedly confessed to killing and dismembering a classmate kept a severed cat head in her refrigerator, according to a media report.
The teen was arrested last week on suspicion of murdering Aiwa Matsuo, 15, after police discovered her body on a bed in the suspect’s condo.
The girl has reportedly told investigators that she “wanted to dissect someone.”
The grisly case has attracted major media attention in a country with one of the world’s lowest crime rates, as commentators search for answers to explain the teenager’s pattern of increasingly violent behavior.
Some reports have suggested the parents of the girl — who has not been named because she is a minor — desperately sought to have her hospitalized but were rebuffed.
On Tuesday, the Mainichi Shimbun said investigators found a severed cat head in a refrigerator and about ¥1 million in cash in the condo where the girl lived alone.
She had reportedly been living there since April on the advice of psychiatrists after she struck her father with a baseball bat.
The father has been quoted as saying that “my daughter’s act can never be forgiven.”
The man — who remarried about three months ago after the girl’s mother died of cancer last year — is believed to have given the cash to his daughter.
Also Tuesday, it was reported that the suspect told her stepmother that she planned to murder a person after growing bored with killing animals.
A day before the incident, her parents consulted with a psychiatrist and tried to get the girl hospitalized, but the request was turned down due to lack of space at the facility, according to the father.
He said he then called a local child welfare office, but a security guard told him to telephone back after the weekend.
