It really is a puzzler and has been one of the main mysteries for me in this case. For why the person may have not continued to keep shooting I have thought of a few possible reasons. *They may have been standing too far from her to be able to be accurate and maybe after they took careful aim and fired and saw she did not react, then they may have realized there is no way they would ever be able to hit her, so they just ran out of there *They may have took careful aim and thought they did hit her and just took off running being too overly confident that they hit her. *The gun may have jammed. If it was a semi-automatic handgun used, then some of those guns can jam. Especially when trying to fire too rapidly. So I guess its posssible they did try to fire more at her but maybe the gun jammed.
