South Africa is gearing up for the Oscar Pistorius murder trial, which is set to begin on Monday.

Pistorius is charged with premeditated murder in the shooting death of his model girlfriend, Reeva Steenkamp.

The double-amputee track star maintains that he accidentally shot Steenkamp in the early hours of Feb. 14 last year because he thought she was an intruder.

Prosecutors say the victim’s clothing will help them secure a conviction. They say she was found dead in shorts and a top, which they say she wouldn’t sleep in. They say she was trying to get away from Pistorius.

Defense attorneys David Schwartz and Jonna Spilbor discussed the case today on “America’s News Headquarters.”

Responding to the prosecutors’ clothing argument, Schwartz said, “I don’t think that’s the greatest piece of evidence but certainly a piece of evidence in this whole story.”

The two lawyers also discussed witnesses who say they heard the couple arguing that night. Spilbor said that those witnesses were 600 yards away, which is too far to hear an argument.
