A dug-addict former nurse who kicked, smothered and slapped a four-year-old girl in a campaign of brutal emotional and physical abuse has been jailed for three years after surviving a joint suicide attempt which killed her boyfriend.
Katherine Walker, 26, attacked the child while looking after her on a two-week holiday with her boyfriend in Western Australia.
She even threatened to kill the girl, telling her: 'Go to sleep before I come in here and pummel you until you die.'
Walker held a pillow over the girl's face and said 'I want to smother you until you die'. She tormented the girl by asking 'can you breathe, can you breathe?' and called her a 'stupid c***.'
Walker also lifted the girl up by the hair and dropped her on a tiled bathroom floor after taunting that she failed to wash properly. While the girl was crying on the floor, Walker kicked her into the wall.
Walker then took the girl into a bedroom where she rolled her off a mattress and kicked her in the back repeatedly.
The former nurse also poked the girl, squeezed her nose, and poured chilli sauce into her mouth while grabbing her hair.
Walker's lawyer claimed she could not recall the five separate assaults because she was high on oxycodone, aka hillbilly heroin, at the time.
She was prescribed it for endometriosis before becoming addicted, he said.
Walker's boyfriend tried to film some of the assaults on his mobile phone in a failed attempt to stop her.
After she was charged, Walker and her boyfriend made a suicide pact to take an overdose of drugs.
But, after the overdose which killed her boyfriend, she was caught on CCTV stumbling out of the apartment they were staying in,
ABC reported.
