Oscar Pistorius' defence team calls up ballistics expert
A ballistics expert is testifying for the defence at the murder trial of Oscar Pistorius, who killed his girlfriend in his home last year.
Wollie Wolmarans, a former police officer, said that his analysis of the scene where the Olympic athlete shot Reeva Steenkamp differs in some ways from the reconstruction of the shooting by police investigators.
The study of the sequence and trajectory of bullets that struck Ms Steenkamp through a closed toilet door is at the centre of testimony over her body position at the time of the shooting, and also relates to the defence's contention that police investigators made mistakes.
Pistorius says he shot Ms Steenkamp by mistake, fearing there was an intruder in his house. The prosecution says the double-amputee runner killed her after an argument.
