Oscar Pistorius' trial: Michelle Burger correctly heard Pistorius' pause after firing the first of four shots.

Crime investigators had labelled the four bullet holes in the bedroom door as A,B,C and D starting from the left to right. A close scrutiny of the trajectories taken by the bullets through the door indicate that the farther right bullet, D, has a trajectory different from the rest of the three. This tells us that D is the first bullet to have been fired by Pistorius. This was not meant to be a warning shot given to an intended victim but meant to receive finer inputs of the exact location of Reeva behind the door. After receiving the input [screams of Reeva] he discharged the other three bullets [C,B and A] from a right to left direction, intending not to kill, but to 'amputate' Reeva's legs. Had his intention been to kill and not maim Reeva, he would have pointed the muzzle upwards and not downwards.
