It seems impossible but stories of children who kill other children are a painful reality for the people of Australia.
It was only in 2006 when two young Perth girls decided to kill their friend Eliza Jane Davis just because they’d woken up with the idea.
The story of Davis gripped the nation as they mourned for the 15-year-old victim of such a devastating crime.
Davis had been flipping through a school yearbook when she was approached by her two friends.
In a series of brutal movements, the girls grabbed her, shoved a chemically soaked rag into her mouth mouth, wrapped her neck in a speaker wire and pulled until she choked to her death.
It seems impossible to think they dragged her body beneath the house, buried it in a shallow grave and then helped the family look for her when she went missing.
It seems impossible but it’s all too real.
The original reportage by Sydney Morning Herald reveals the chilling explanations the killers gave in their police interviews.
“Sunday morning me and (her) woke up, and we were just talking, and for some reason we just decided to kill her,” one said.
“We just did it because we felt like it, it is hard to explain,” the other girl said.
“We knew it was wrong, but it didn’t feel wrong at all, it just felt right.”
The two unnamed girls were given sentences of 15 years to life and are currently serving in Bandyup Women’s Prison in north-eastern Perth.
The story of Davis may sound horrific but it is not unique. There are over 40 cases where children have killed other children and seven of those are Australian.
