The double amputee, deliberately or accidentally shot to death his girlfriend, model Reeva Steenkamp, during the night on Valentine's Day 2013. It's a case that is drawing comparisons to the O.J. Simpson double-murder trial in the U.S. in 1995 and it certainly will rival that for media attention worldwide. The trial will be televised, although testimony by Pistorius or witnesses who do not consent will not, and it will be riveting.
Pistorius faces one charge of premeditated murder and a firearms charge in addition to gun charges from previous incidents. A conviction on the murder charge in South Africa would carry a mandatory life sentence.
This much seems certain: Steenkamp was in the toilet closet in the bathroom of Pistorius's home in the middle of the night and died after Pistorius shot her through the door. He does not claim self-defense.
The trial is scheduled to last 3 weeks, but chances are that it will last longer than that.
