A Perth man has been found guilty of raping a 76-year-old woman while his son was getting his leg amputated in surgery related to cancer treatment.
Mugahed Adam Eldouma, 39, got into the victim's Armadale house on a June afternoon last year through a window, leaving behind fingerprints, then snatched her mobile phone before punching and sexually assaulting her.
Eldouma, who initially claimed he was the victim's carer and she was "like my mum", was convicted of four offences by a West Australian District Court jury on Friday after they deliberated for less than one hour.
He kept his head down as the verdicts were delivered but otherwise showed no emotion, news.com.au reports.
On Friday, the court heard the victim's screaming through the airing of an emergency call from the attack.
