Oscar Pistorius trial, toilet door set up in court room
"We had been to the shooting range before and I knew he had a big love of weapons," said Darren Fresco in his testimony during the South African sprinter's trial for shooting dead his girlfriend.
He faces a fourth charge of illegal possession of unlicensed ammunition.
Fresco was with Pistorius when he fired a gun through the sunroof of a moving car in 2012. Pistorius shot at a traffic light after a row with traffic police. Fresco and Pistorius's then-girlfriend Samantha Taylor were also in the car.
Pistorius shot Steenkamp four times with a nine millimetre pistol on Valentine's Day last year in what prosecutors charge was premeditated murder and he says was an accident.
The 29-year-old model and aspiring actress was hit once in the top right of her head, once in the right elbow and once in the right hip. She was also struck in the webbing of her left hand.
