Police have confirmed that the 35-year-old George mother, Heidi Scheepers and her two-year-old son, Hugo drowned.
Hugo's body was recovered from the sea near Herolds Bay late last week and Heidi's over the weekend after parts of the wreckage of Scheepers' VW Caravelle were found partially submerged in the ocean at the bottom of a 100-meter high cliff at Voëlklip.
Police spokesperson Captain Malcolm Pojie says the search for 6-year-old Cuzette Scheepers continues.
He says teams are currently working in very rough sea conditions.
Heidi and her kids were reported missing last week when they never returned home from an outing to the beach.
