And with the trial of his suspected murderers in its fourth day, not one of the witnesses has identified the people involved. A motive behind the killing has also not been divulged.
Bozwana was at the time of his death embroiled in legal proceedings with the North West province regarding alleged tender irregularities.
His lover, Mpho Baloyi, who was driving the car on the day of the shooting, and who was severely injured by the bullets, has testified that she had no idea who fired the shots or exactly where they came from.
She told the Gauteng High Court, Pretoria, that she simply saw the door open of a luxury BMW sports car, which stopped behind them at a red traffic light at the off-ramp.
However, she did not see if anyone got out of the vehicle or who fired the shots that killed Bozwana.
Another witness, who worked in the vicinity of the off-ramp, testified that he heard shots and saw someone from a distance shooting, but he, too, could not identify the gunman.
Taxi owner Mmiselani Dlamini took the stand on Thursday and testified that he knew three of the accused - Sipho Patrick Hudla, 34, Matamela Robert Mutapa, 40 and Bonginkosi Paul Khumalo, 36. All of them were members of the Alexandra Taxi Association.
However, he did not know accused Vusi Reginald Mathibela, 30, the man the State claimed pointed Bozwana out to the other accused at Sandton City shortly before the incident.
Dlamini testified that he and the three accused he knew were at the office of the taxi association on the morning before the incident.
Dlamini said he owned a car, but could not drive. He usually asked a friend to drive him around in his own car.
On that morning, Khumalo asked him to drive with him - in Dlamini’s car - to Sandton City. According to Dlamini, Hudla and Mutapa drove behind them in a double cab vehicle.
He and Dlamini parked in the basement of the mall, but he did not see the other two at that stage.
He testified that Khumalo asked him to wait for him in the basement. Dlamini waited for about two and a half hours, when Khumalo phoned him to tell him he was already back at the office of the association.
Khumalo then sent a queue marshal to fetch Dlamini and his car at the mall.
When they got back to the office Mutapa gave him R2000 to “thank him for his patience in waiting for Khumalo”, the court was told.
Dlamini said he was at first also arrested alongside the other accused for the incident, but he was freed after two days when he could not be linked to the incident.
The State claimed that the accused followed Bozwana and Baloyi while they were shopping at Sandton City and later had lunch at McDonald’s in Grayston Drive.
It is also claimed that the couple were followed when they took the N1 to Pretoria.
CCTV footage, which had been placed in dispute by the defence, allegedly depict the accused and other unknown men on these scenes.
