The time line is important in terms of the screams yes, but more specifically, the defence wants it to be in a single rapid burst to show it was more of a panic...
With Mangena we had Bang...BangBangBang, with Wollie and defence BangBangBangBang. Neither of these explain the differences in position of the deceased...
Now to give you my personal description based on what was heard in testimony so far.
1. First shot hits A on door and hits Reeva's hip (height matches) cannot wish it away. Fixed.
2. Reeva does not collapse as suggested (remember she can have most of her weight on the left leg) and moves to the left, far enough for the second bullet, through B to miss her and strike E. The bullet passes however close enough to her forearm for wood splinters to cause the marks there. As she is still close to the door, between the toilet itself and the door. The bullet ricochets of E, strikes F then hits her back with much less energy to only cause a bruise and falls into the toilet.
3. She then starts to fall backwards, as she tries to place some weight onto the right leg, but it buckles and number three hits her arm.
4. Still going down number four is the head shot.
Therefore... Bang...(slight delay and screaming)... Bang... (More screaming as she goes down)... BangBang (rather quick succession while falling to strike the arm and the head). C and D is also quite close together on the door, similar to a double-tap...
