His voice trembling with emotion, Oscar Pistorius took the witness stand in his own defense Monday, saying the Valentine's Day shooting of his girlfriend last year had left him sleepless, terrified and plagued by nightmares.
The disabled South African track star, on trial for murder, apologized to the mother of model Reeva Steenkamp, saying he had fired four times through a toilet door at his luxurious Pretoria home in the belief he was defending her from an intruder.
Steenkamp, a law graduate and model, was hit by at least three rounds, one of which — to the head — killed her almost instantly, the court has heard.
