A man has been found guilty of murdering his wife of 50 years by strangling her with an extension cord in their Melbourne home.
A Supreme Court of Victoria jury on Tuesday returned a guilty verdict for Anastasios Karatzas, who killed his 68-year-old wife Georgia on November 20, 2017.
In the days before he killed her, the 70-year-old murderer told his wife he felt "lifeless", prosecutors said during Karatzas' trial.
Mrs Karatzas' elderly mother, who lived with the couple, found her daughter dead and facedown in the laundry, dressed in her nightie, with an extension cord protruding from beneath her body.
Mrs Karatzas died from compression to the neck and also received blunt-force trauma to the head.
After the murder, Karatzas - who suffered depression - left the house he shared with his wife and mother-in-law and was reported missing by family.
He was arrested when he turned up at his sister's home the next day.
Karatzas' barrister Patrick Tehan QC asked the jury to find the killer guilty of manslaughter rather than murder, arguing the septuagenarian loved his wife deeply.
But the jury rejected that alternative charge.
Karatzas is due to return to court on July 24 for a pre-sentence plea hearing.
