The girl, named as Luda and described by local media as smart and spirited, was hammered to death at her home in the city of Taraz, northern Kazakhstan.
She was found with a broken skull and died from horrific injuries before paramedics arrived at the scene.
According to the neighbours, the tragedy occurred after Luda and her brother Aleksey, 15, had a row in the courtyard near their house.
A neighbour who witnessed the incident said:
He then reportedly carried her body and dump it in the street near his neighbours’ fence.
After dumping the body, Aleksey allegedly changed his clothes and alarmed his parents by telling them that ‘his sister disappeared’, according to local media.
The family rushed to search for the girl and Aleksey, who ‘actively helped’, led them to the body, before his parents called authorities.
Law enforcement launched a criminal case for murder against Aleksey who confessed to the crime. He faces up to 15 years in prison if found guilty.
