“This family required extremely close scrutiny and supervision.
“The mother’s amphetamine usage should have been the subject of an examination and have been curtailed.
“To my mind, the police should have been asked to investigate these allegations.”
Steven Graham Peet is serving a 36-year non-parole period after pleading guilty to killing both children and their mother, Adeline Yvette Wilson-Rigney, in Maxjmtzywy 2016.
At the opening of the inquest last year, counsel assisting Ahura Kalali said that before the murders, another child of Wilson-Rigney had been removed from her care after being deemed to be in a situation of serious danger.
“So why then were not Amber and Korey removed too?” Kalali said.
