Okay, if you haven't figured it out it's actually this woman on the right here
even the Wiegman film shows her already down on the ground, so what Paschall tells us is that after going to ground she got up again for some reason and during the filmed clip goes back down to the grass.
I think she may have reacted to Hargis running toward her and became scared and or confused again.
Watch the Paschall clip again and see it happen, seconds before this clip starts Hargis ran across the street directly toward her, Wiegman and to some degree the Hesters, they all react.
