The trial of a man facing culpable homicide charges after former president Nelson Mandela’s granddaughter was killed in an accident where he was driving, continues in the Johannesburg Magistrate’s Court on Friday.

Sizwe Mankazana, 25, also faces charges of reckless or negligent driving.

He was driving Zenani Mandela home from a World Cup concert when the car hit a steel barrier, which pierced the vehicle. Zenani died. Mankazana and another passenger were slightly injured.

That passenger, Mankazana’s cousin Stacey-Lee Louters, testified in Thursday that Mankazana had only one drink the night of the accident.

“To my knowledge, I remember him having one drink after refusing everything else I was offering him.”

She and Mankazana had tried to find someone else to take Zenani home from the concert, she told the court.

“But no one else was going in that direction and Zenani wanted us to take her,” she said. Winnie Madikizela-Mandela had also asked Mankazana to take Zenani home.

The three left the stadium in Mankazana’s father’s car and got lost on their way out of Soweto. Their GPS had led them into the city.

“We re-entered our home address and off-ramped. Then the accident happened on the off-ramp,” said Louters.
