A defence witness in the murder trial of South African athlete Oscar Pistorius says the victim, Reeva Steenkamp, was shot four times in quick succession.
Forensics expert Roger Dixon claims Ms Steenkamp was standing at an angle to the toilet door and was hit by all four shots as she fell.
This challenges the state version that Reeva Steenkamp screamed out in the pause between the first and second shots.
Oscar Pistorius says he fired rapidly out of fear through the locked toilet door.
Prosecutor Gerrie Nel tried to discredit the qualifications and experience of Mr Dixon.
The witness made it clear throughout that he was not a ballistics expert, something the prosecution seized upon.
Dixon is a geologist and former head of material analysis at a police forensic laboratory in Pretoria where he worked for 18 years.
Oscar Pistorius says he shot his then girlfriend after mistaking her for an intruder.
