Two shots at the same instant?Some witnesses reported a ba-bam sound at the last shot.Down & forward then back and to the left
The shot was from the front and exited in the rear as shown in this animated GIF (large file may take a moment to load).https://drive.google.com/file/d/0B7Hr9Lrku-Cxdm9ZalJTSWU3cms/view?usp=sharingIf you look at the above, you can see what appears to be a puncture in the scalp and it lines up very well with beveled hole in the skull. The entrance of this shot was most probably the temple, thus, causing the backward motion of the body.
