Callum Ferris Davies was found guilty of sexually assaulting a seven-year-old girl

A man with autism spectrum disorder has been found guilty of a horrific sexual assault on a sleeping seven-year-old girl in the north-east Perth suburb of Ellenbrook.

Callum Ferris Davies, 28, claimed he suffered from an intellectual disability, but this was rejected by the judge.

Davies was caught on CCTV climbing over a backyard fence before attacking the helpless child.

It was just after midnight on December 27, 2021 when the Oakfield man broke into the home and the little girl’s bedroom.

When she woke up, she found her mouth “taped shut” and was told to be quiet before she was “smothered unconscious,” she told police.

She later woke up in a different pajama top than the one she had gone to bed in, and Davies turned himself in to police days later.

The now 28-year-old admitted committing the sexual assault but said he was in a state of psychosis and unable to control himself.

But after hearing all the evidence presented to the court, the judge refused.

Davies will serve his time – which will be decided at a court hearing in January – in prison rather than in a mental health facility.
