Did “roid rage” — a state of heightened anger and aggression linked in popular culture to anabolic steroid use — play a part in Paralympic track star Oscar Pistorius allegedly killing his girlfriend on Valentine’s Day?
If so, could it help in his legal defense?
According to media reports, police found anabolic steroids and other PEDs while searching the Pretoria, South Africa home of Mr. Pistorius, 26, charged with premeditated murder in the shooting death of 29-year-old model and law school graduate Reeva Steenkamp.
Mr. Pistorius, one of the world’s best-known athletes, appeared in a packed Pretoria courtroom Tuesday and denied he intended to harm Ms. Steenkamp when he reportedly fired four bullets, three of which struck her, through a closed bathroom door at his home. He said he heard a noise from the bathroom in the middle of the night and opened fire out of fear.
Prosecutors, by contrast, contend that the killing was intentional.
