PRETORIA, South Africa (AP) ― Prosecutors in the Oscar Pistorius murder trial on Thursday displayed a sequence of photos showing the blood stains and blood spatter found on the floors, walls, stairs and chairs in the athlete’s house after he fatally shot his girlfriend.

In one photograph displayed on TV monitors in the courtroom, spots of blood were seen right next to some of the double-amputee Olympian and multiple Paralympic champion’s golden trophies. The TV screen next to Pistorius, who at times held his head in his hands, was switched off during the display.

The images were described by G.S. van Rensburg, a former police colonel who testified at the trial as one of the two officers first on the scene after Pistorius killed Reeva Steenkamp on Valentine’s Day last year by shooting her through a closed toilet door in his home.

Pistorius, 27, has said he shot 29-year-old Steenkamp by mistake, fearing there was a dangerous intruder in the house. The prosecution says he intentionally killed her after an argument.

Van Rensburg described how, on arriving at Pistorius’ house, he saw Steenkamp’s body covered in towels and plastic bags that the daughter of the estate administrator said she had used, with assistance from Pistorius, to try and stop the bleeding. A tearful Pistorius was pacing in the kitchen, van Rensburg said. The policeman said he asked the athlete what had happened, but he didn’t answer.
