PRETORIA, South Africa (AP) — The seventh witness in the Oscar Pistorius murder trial provided emotive and at times gruesome testimony Thursday on the double-amputee runner’s distraught actions and the fatal injuries of his girlfriend immediately after she had been shot three times — once in the head — on Valentine’s Day last year.

Johan Stipp, a doctor, neighbor and one of the first responders on the scene, said he found Pistorius desperately trying to help Reeva Steenkamp after carrying her downstairs from the bathroom where he shot her. The star athlete claims the shooting was a mistake. Stipp said “it was obvious that she was mortally wounded.”
