I think June passed out/collpased after walking round for half a dozen or seconds after being shot. The subsequent shots were probably overkill.
June had a number of wounds upon her legs. Curved cuts, quite pronounced. It is also possible that her head was thrust backwards (for example by a hand / fingernails / thumbnail). She had a nasty gash to her chin and marks across her throat: where blood collected and the skin was broken in places. As is already known, June also had a black eye which (rightly or wrongly) was not attributed to a fight.
