Interesting piece of the article TWDeac linked (which I finally just read):
Steenkamp was wearing her nightie at the time. When the police inspected Oscar’s bedroom, they found her overnight bag and iPad on the floor. A holster for a 9mm pistol was found on Oscar’s side of
the bed.
The bedclothes were crumpled. “It was clear that both of them had slept in the bed,” said a police source.
One cartridge was found in the bedroom and the police suspect Oscar may have “chased” her and fired the first shot before Steenkamp could lock herself inside the toilet.
“The suspicion is that the first shot, in the bedroom, hit her in the hip. She then ran and locked herself in the toilet. She was doubled over because of the pain. He fired three more shots. She probably covered her head, which is why the bullet also went through her hand,” said a source.
Steenkamp was shot in the head, hip, arm and hand.
In anticipation of a possible argument that he experienced “roid rage” – extremely aggressive behaviour associated with taking large doses of steroids – the police insisted that the athlete’s blood be tested for any foreign substances.
