The business partner and lover of North West billionaire Wandile Bozwana told the North Gauteng High Court in Pretoria that she heard several shots being fired at them as they stopped their car at the Garsfontein off-ramp, east of Pretoria, in October 2015 but she could not see where the shots came from or who fired them.
Mpho Baloyi was severely injured when about 12 shots were fired at her and Bozwana. She, however, recovered in hospital from her injuries.
Bozwana, who was in the passenger seat of the car driven by Baloyi, died a few hours after the shooting in the Unitas Hospital.
He tried to shield Baloyi from the bullets by leaning over to her side and covering his body with his.
The four men accused of the murder and attempted murder this week pleaded not guilty to the charges. They said they knew nothing about the incident.
