The three boys died in the crash

A 71-year-old Wellington great-grandmother has been found guilty on three charges of premeditated murder after admitting to deliberately driving a vehicle carrying her three great-grandchildren off Bainskloof Pass, resulting in their deaths.

The case stems from a tragic incident on November 20, 2021, when Susana "Sarie" De Villiers drove through roadwork barriers near the top of Bainskloof Pass before plunging approximately 80 metres down the mountainside.

Killed in the crash were two-year-old Joshua Booysen, five-year-old Gradwell Booysen and eight-year-old Caleb Booysen. De Villiers survived the incident.

The Worcester Regional Court previously heard that the three boys had been living in foster care for about six months before their deaths after concerns relating to their parents' substance abuse led to their removal from the family home.
