APTOPIX South Africa Pistorius Shooting

Oscar Pistorius' defense is trying to poke holes in the murder case against the Olympic track star in South Africa.

FOX News Radio's Jeff Monosso reports:

Investigators in the South African court today say that witnesses heard nonstop shouting shortly before Reeva Steenkamp was shot dead and that containers of testosterone and needles were found at the scene.

But the defense points out that one of those witnesses lives hundreds of yards away and that the containers were filled with herbs.

But police also say that the shots appear to have been fired in a top-to-bottom trajectory, suggesting Pistorius was wearing hisĀ prostheticĀ legs when he pulled the trigger, and countering his story.
