Evil Parents Lock Their Daughter in a Room for Over 15 Years Leaving Her to Freeze to Death

A Japanese couple have been arrested after allegedly imprisoning their daughter for more than 15 years before she froze to death aged 33 this month, report says.

According to information by a local media on Wednesday, Osaka residents Yasutaka Kakimoto, 55, and his wife Yukari, 53, admitted to locking their daughter Airi in a small room from the age of around 16 or 17, Kyodo News said.

An autopsy showed Airi had frozen to death and was extremely malnourished, weighing about 19 kilogrammes (42 pounds).

The parents told police they confined their daughter because she was mentally ill and acted violently, national broadcaster NHK said, adding that the room had an intercom that the family used to communicate.

They reportedly fed their daughter about once a day. They also used more than 10 surveillance cameras to monitor her movement around their house in a possible attempt to hide their secret, according to newspaper the Yomiuri Shimbun.

After reporting her death to police, the couple were initially charged with illegally disposing of a body but police were also considering other charges including confinement, Kyodo said.

Osaka police did not immediately respond to requests for comment Wednesday evening.
