The girlfriend of Oscar Pistorius was shot in quick succession as she fell down, a forensics expert has told the South African athlete's murder trial.
This differs from a police ballistics witness who said there was short break between the first and second shots.
Mr Pistorius denies intentionally killing Ms Steenkamp in early hours of Valentine's Day last year.
He says he fired rapidly in fear through the toilet door after he mistook Ms Steenkamp for an intruder.
