Teen Admits Killing 6-Year-Old Sister After Getting 'Tired Of Taking Care' Of Her

A 17-year-old boy in Japan reportedly admitted in court to killing his 6-year-old sister before dumping her body in a children's playground and claiming she fell off a jungle gym.

The girl had several broken ribs and more than 100 bruises on her body when she was found dead on Aug. 1 in a playground in the city of Otsu in Shiga Prefecture, Yahoo News reported.

The trial of the child's brother, who is accused of beating the 6-year-old to death, started on Aug. 25. Both siblings' identities were not disclosed.

On the morning of Aug. 1, the teen rushed to a private house near the Otsu park for help, saying, "My sister fell from a jungle gym," Japanese news outlet Mainichi Shimbun reported.

An unnamed resident who saw the girl collapsed in the playground told the publication that he heard the boy muttering to himself, "Can they save her? Will I be blamed?"

Police were called to the scene and facilitated the transfer of the young girl to a hospital. She was declared dead shortly after her arrival.

After an autopsy found that the child had over 100 bruises and that several of her ribs were broken, her brother was arrested on suspicions of inflicting bodily injury resulting in death. Authorities alleged that the 6-year-old had been brutally beaten on her stomach and back.

The boy allegedly later told police, "I was tired of taking care of my sister," Mainichi Shimbun reported, citing investigators.

The case was forwarded to the Otsu District Public Prosecutors Office, which referred the case to a family court.

The two minors are said to have come from a neglected family. Their mother allegedly failed to take care of the siblings, leaving them to beg on the streets just to buy food.

The girl was previously questioned by police on July 20 after she pestered strangers in a shop by asking for spare change.

The 6-year-old was escorted by police back to her home, but they discovered that her mother was not around. They left the girl with her brother, unaware that he too was underage.

The teen had just started to live with his mother and sister in April, according to the prefectural government's child consultation center.

Due to financial difficulties, the boy had been living at an orphanage in Kyoto Prefecture since he was in elementary school. Meanwhile, his sister had been entrusted to a facility in Osaka Prefecture a year after she was born.

The teen's trial is ongoing.
