The grandfather of two young SA children murdered with their mother yelled at their killer after he was sentenced to a minimum of 30 years in prison.
Steven Graham Peet appeared in the Supreme Court on Friday after earlier pleading guilty to killing Adeline Yvette Wilson-Rigney and her children, Amber, six, and five-year-old Korey at a property north of Adelaide in May, 2016.
Justice Malcolm Blue said the murder of the children was a ‘senseless and incomprehensible act’ in sentencing him to the mandatory life term.

He said he would have sentenced him to 33 years non-parole had it not been for Peet’s eventual guilty pleas to all three murders.
After the sentence was handed down, Steven Egbert, the children’s grandfather, yelled ‘we’ll be here when you get out you weak little f****’ before being removed from the court by security.
Another yelled out ‘animal’ as Peet was led away.
The bodies of Ms Wilson-Rigney and the children were all found with cable ties around their necks and hidden under clothes and bedding and, in the case of the boy, under a child’s play tent.
The young girl had adhesive tape wrapped around her head and a sock had been stuffed in her mouth.
Her arms had been tied behind her back.
The young boy had parts of his body wrapped in tape and his hands and feet were secured behind his back in a hog-tied fashion.
Peet and Ms Wilson-Rigney had been dating since February 2016, the Supreme Court heard.
After the attack, Peet confessed the crime to a relative.
‘I killed my lady and her two kids,’ he later told police on the phone, according to ABC.
