PRETORIA, South Africa (AP) — Standing with his arms straight out in front of him and gripping an imaginary pistol in court, a South African police ballistics expert showed Tuesday how he estimated the trajectory of the four bullets Oscar Pistorius fired through a toilet door while standing on his stumps to kill his girlfriend.

Capt. Christiaan Mangena said Pistorius shot at a slightly downward angle into the cubicle where Reeva Steenkamp was, with the bullet holes around a meter (3 feet) high in the wood door. Pistorius was about 2.2 meters (7 feet) away from the door when he shot, Mangena said.
