Oscar Pistorius trial details Reeva's last horrifying moments: Video

It was a long day of complicated ballistics evidence and testimony in the Oscar Pistorius trial where the accused stands trial for the killing of his girlfriend Reeva Steenkamp. Testimony today centered around the defense team's trump card, a ballistics expert that has earned the respect and a reputation in South Africa that is almost unprecedented, according to CNN. CNN reports that defense witness Tom Wolmarans, former police office and accomplished ballistics expert, refuted what the prosecution has tried to establish thus far in terms of Reeva's last horrifying moments.

Precisely how Reeva died and what happened in those last fatal moments remains unclear, even after testimony today. CTV Toronto reports the ballistics evidence presented today directly contradicts what the state has attempted to establish thus far, and might just be enough for the judge to play the reasonable doubt card.

The prosecution has tried to establish the theory that Reeva had her hands over her head in a defensive position when she died, which would support the theory of premeditation.

Ballistics expert Tom Wolmarans asserted in testimony today that this just was not possible. "The left hand cannot have been against her head" he testified, according to CNN. He further testified that the lack of evidence against Reeva's hand, blood and tissue, was not consistent with her having her hand against her head when she died.

It's important testimony to the defense, as if her hand had been near her head when she died, prosecution is alleging that would mean she was in a defensive position trying to fend off a premeditated murder. With her hand not near her head, the defense is working to suggest that these shots took her by surprise, supporting the intruder theory the defense has offered thus far.
