Where are you getting that information? That is not in any of the links you provided. How about just pasting a direct quote from the military leader who made this statement? Thanks!!
It is here in MS Word .doc and Adobe .pdf:

Short version...Pfc. Lynch was riding in a HMMWV and got into a serious accident and was captured.
It seems she was confused and praised over the true hero of that ambush:
Mom says killed son mistaken for Lynch in Iraq (Sgt. Walters was the true hero)
Pvt. Lynch deserves her Purple Heart and her POW medal but she does not deserve at all the Bronze Star.
