This accident occurred in 2008 & yet hasn't come to a conclusion... guess their laws don't promote a speedy trial.
Since he wasn't under the influence, seems accidental would be the verdict.
in part:
Carl Pistorius is charged with culpable homicide in the death of a motorcyclist in 2008;
"Blood tests conducted by the police at the time proved that he had not been under the influence of alcohol, confirming that it was a tragic road accident after the deceased collided with Carl's car."
