The family of Karen Ristevski is preparing for Sarah Ristevski to break her silence after her father Borce killed her mother and then lied about it for years.

Sarah is estranged from her mother's side of the family and has had little contact with them after her father was charged with murder in 2017.

She has rarely spoken in public since the death, appearing only at court hearings that led to Borce being jailed for a maximum of 13 years for manslaughter.

But she has now broken her silence, telling the 60 Minutes program that she asked her father whether he was involved in her mother's death.
