Pistorius lawyer queries evidence

The chief defence lawyer at Oscar Pistorius’ murder trial has pointed out alleged missteps by police and questioned their treatment of evidence during the investigation into the athlete’s killing of his girlfriend.
Lawyer Barry Roux cross-examined a police forensics expert for a second day, challenging his analysis of a bullet-marked toilet door that was removed from the bathroom at Pistorius’ home, where the double-amputee athlete fatally shot Reeva Steenkamp before dawn on February 14, 2013.
