Pretoria, South Africa (CNN) - Sounds of arguing for an hour before the shooting. Blood stains on a cell phone and cricket bat. Boxes of testosterone and needles. Angles of gunfire.
The shape of prosecutors' case against Oscar Pistorius began to come into focus Wednesday as they argued the Olympian charged with killing his girlfriend is a flight risk who should be denied bail.
Police investigator Hilton Botha told the court there's no way Pistorius was acting in self-defense when he shot through the door of a toilet room in the bathroom of his home and killed Reeva Steenkamp.
Pistorius has said he thought he was shooting at an intruder in the early hours of Valentine's Day, but Botha said he believes Pistorius knew Steenkamp was on the other side of the door.
Prosecutors tried to poke holes in Pistorius' story, and defense lawyers fired back: The witness who heard sounds of arguing lives 600 meters (more than 650 yards) away, Botha testified under cross-examination. Pistorius had a legal herbal medicine, not testosterone, defense attorney Barry Roux said. Steenkamp locked the toilet room door when she heard Pistorius screaming for help, Roux said.
With all these new details, how will Pistorius shape his defense? This morning on "Early Start," legal contributor Paul Callan weighs in on the case.
