The prosecution in Oscar Pistorius' murder trial on Thursday challenged the credibility of an expert witness for the defense, which was trying to show that the athlete killed his girlfriend by mistake.

Roger Dixon was called by the defense to give evidence to support Pistorius' story that he killed girlfriend Reeva Steenkamp by accident thinking she was an intruder behind the toilet door in his home and about to attack him.

In one, the prosecutor criticized Dixon, a geologist, for not using the exact height of double-amputee athlete Pistorius when standing on his stumps.

"It is something I omitted. I overlooked it at the time," Dixon replied when questioned why his measurements were around 20 centimeters (8 inches) off in a test to see if Pistorius' head and body would have been high enough to be seen by neighbors through a bathroom window. He said he was not trying to "mislead" the court.
